A\N: Not Gonna lie, I expected a few of you to jump at the opportunity of challenges and go crazy. But hey every reading is a win in my book, Got myself a nice start right? So I let you all with one more chapter. I think you guys will like the challenge theme, it goes well with the reward.

After experiencing firsthand what Melvin was capable of and facing some of the challenges given to him. Yamcha still didn't know much about the guy, but every bit of info was another piece of the puzzle, his power to teleport great distances, having some sort of white void pocket where he seems to create stuff from scratch? Was he able to do everything at any time? Or was there more to it?

He did remember that he told something about having to recharge power, but the former bandit prefers to not ask too many questions, for now, maybe once they get to know each other more. It sure was fun to have that book, new techniques to spend your time learning instead of doing the same training over and over, maybe this would help him find something more about said skills and make his version? Perhaps.

"...Great Power...minimum strength"

And right now Yamcha was in front of a boulder the size of a truck, concentrating on breaking it to fine dust using minimum strength yet great power as the book basics told him. Yamcha didn't tell about Melvin yet to his good old friend Puar who lived with him, first, he was trying to come up with a good explanation for it without looking crazy. Next time he would probably have it ready.

"Looks like you're having fun" Melvin said, showing up behind him in a flash.

"You really enjoy showing up like that huh?" He said not even looking back.

"Glad to see you didn't gasp in surprise again, that's that"

"I do have to concentrate in this training more than normal, also I can sense your ki signature''

"At least the normal kind'' He whispered.

"You said something?"

"Yeah! I wanted to see some new moves, when are you gonna start showing off?" Melvin grins.

"First of all, they are not ready ok? I want to get this right to the minimum detail, and more! ...Even though I would indeed enjoy showing off a new move right now it's not the right time" Yamcha pouts a little.

"So! Did you tell your blue friend about our deal?"

"Not yet, I'm still figuring out a better way to say it"

"C'mon you don't need to act all weird, it's not like the shapeshifting talking cat won't understand the situation" Melvin said like their whole interaction was to be expected.

"Living through weird things doesn't make that much easier to speak about it" Yamcha tried to be logical.

"Yeah it does, you just need to do it with style"

"Ok let's get to the point, do you have something for me?" He said turning around.

"Of course, every time I show up is either for the next challenge for the training or to mess around. Sometimes both hihi"

"Ahn...Ok? Well, can I say no so to focus more on what I already have?"

"Of course you can but...this one is gonna be real fun, and if you say no we are gonna have to wait two more weeks, c'mon man pleaseeee" Melvin said trying to make his eyes cute, anime style.

"O-OK just stop looking at me like that, it's creepy" Yamcha cringed.

"Oh, Noice! Shall we go?"

"Fine, just try to not hide too much from me in this one ok?"

"As you wish. But before would you care to take a deep breath?"

Yamcha tilts his head wondering why he would ask that specifically "Why? Are you gonna test how much I can hold my breath?" He smirked at the idea of such a simple thing.

"Yeah...sure" Melvin said, his eyes looking away for a moment.

Shrugging that off, Yamcha calmy starts sucking in the air, filling his lungs from the diaphragm up, with no need for rushing, slowly letting the oxygen fill the guy's lungs until he can feel it closer to his sternum. This reminds him of when he used to swim laps on laps around Master Roshi place, the very top of his lungs were now full causing his chest and shoulders to rise.

"That sounds good enough. Good Luck, show me what your training has made of you, and try not to die" Melvin said with a neutral look on his face.

'Ok then im just go- wait What?' That took him off guard.

The former bandit was left startled as all kinds of events unfolded before his eyes. First of all, he wasn't able to see anything, everywhere went dark as far as the eye can reach, his arms and legs felt heavy like something had wrapped itself around it. And last but not least, he felt immersed in what he could only come to terms with as being water. The chilling and cold temperature as the sensation of pressure in an all-encompassing amount at all sides being the hints.

'W-What just happened? Is this underwater? And...this pressure' He thought, confused about that turn of events.

The former bandit had to keep his cool for the moment if he wanted to know what was going on, wanting to see his surroundings the guy makes a ki ball on his right hand to illuminate the area, however, he was soon surprised by a sudden voice that called to him.

"Welcome to the depth!" It said cheerfully. A glowing orb of green luster shows up by his side.

'Hmhn?'

"If this wasn't obvious enough, you're underwater! And your limbs have been chained down...by chains" The voice of Melvin said.

'Underwater? Oh man, I wonder how deep this is' Yamcha pondered about it.

"Those chains you are currently 'using' are made of Titanium gold alloy, possessing a high yield and tensile strength, four times harder than Titanium. But that's not your biggest problem now" Melvin said with a devilish tone.

'Huh? What do you mean by that?'

"If your so interested in the details then allow me to enlighten you. You're currently 10,984 meters deep in the water where the pressure is 15,750 psi! That is more than 1,071 times the standard atmospheric pressure at sea level Lol! The density of water is also increased by 4.96%. and the temperature is 1 to 4 °C Wow!" The orb said joyfully "Deep, Heavy and cold"

'Yikes, that sounds like a big deal. I never dived that deep before, looks like you made this interesting' He thought, surprised at the piece of information.

"Better start swimming Mister, the dark deep sea is a heck of a spooky place" Melvin then turns off from his orb-like lantern, leaving the man to fend for himself.

'If you think this is enough to make me lose my willpower, then I show you how to escape this water-filled obstacle'

First things first, he has to break free from his restraints and start to get a move on. Every square inch from his body felt the pressure, wrapped around his arms, legs, back, and pretty much everything, it was harder than King kai Planet and reminded him of the gravity chamber as well.

But even though it looked like things were not looking up to him, thanks to years of martial arts training and pushing his body to the limit, it made him strong. As the aura surrounded his body while powering up, Yamcha used pure brute strength to start and tear through the chains with full force, first from his arms with a yank until it finally broke, and then gripping the other ones from his legs like a vice.

'No time to mess around, I need to escape and make sure to hold my breath with no distractions'

The chains were strong, but he was way too ahead in the game to be stopped by something like that. Now free from the restraints he remakes the ki ball to illuminate his path and starts to swim upwards pretty against such struggle but quite fast.

'Ughhn...It feels like I am swimming on wet concrete that is slowly hardening up by the second and it's also hacking cold!'

Even though Yamcha was not the strongest human on earth (That belongs to Krillin) He was no pushover, the pressure, and density of the water was an obstacle, but he would push through, just like his training in high altitude on kami lookout and the gravity on King kai. This made him remember the embarrassing failure that was when he tried using the same gravity Vegeta did once only to almost die. Would that happen here too? No, he couldn't let that scene repeat itself.

'Let's see what you got around here to step it up to me'

Or so he thought, there are always things lurking around in the dark and this was no exception. Yamcha could sense the life force of something, it was small but they were plenty.

'Hmmm? I should look around. Something tells me I am not alone'

"Hope you don't hate slimy things" Came the voice for a moment "It would be a shocker hehe"

'Wait What!?'

Not understanding what that meant, Yamcha is taken by surprise, as his limbs are suddenly enveloped by some humid and snake-like sea creatures. The moment that happened he didn't even have the time to respond, electricity started being sent to his body.

'Guahh!' He screamed, feeling the pain through his body.

Eletricity was dangerous, humans have died at just 42 volts, but is not just the Voltage that can kill humans, the current plays a major factor. A current of 0.1 ampere for a mere 2 seconds can be fatal since th nerves are tissue that offers very little resistance to the passage of an electric current. When nerves are affected by an electric shock, the consequences include pain, tingling, numbness, weakness or difficulty moving a limb or in worst cases, respiratory arrest.

However, that is for a normal human, Yamcha had learned ki control and had been training upon it for a very long time already, this would not be enough to stop him for too long, with a Kiai he pushed those things away from his body.

"Hey good job, those were special Eels capable of sending 50,000 Volts, guess it was not enough to push you down huh?" Melvin laughed as it 'complimented' him.

'What the fuck!? That stung god damn it! My body is shaking, it feels awful' He complained, shaking the feeling off.

"Well Duh, the highest voltage an Eel could do was 860 of voltage normally, what waste right? I mean if it was at least 20,000. No need to cry though, I bet it wasn't even deadly" Melvin said shrugging it off, or what seemed to be it in that form.

'That was dirty, but I will be damn if I let this slow me down, Roga fufu Ken!'

After getting into his favorite stance, with swift and sharp movements as if he was on the surface, the fighter beats down the swarm of Eels that managed to survive in that environment with his favorite combo, each one getting a strike and getting pummeled.

'That's what you get for messing with me, Off I go'

Powering up more of his ki through the body it then starts to give off a surge of energy that covers his frame like a thin layer. After that Yamcha goes back to swimming, much faster than before like he was a living torpedo fighting against what pushed him down, the surprise took some of his time and control but he didn't lose time thinking about that.

'At this pace, I make to be up there in no time'

The further he went from his former prison, the pressure would diminish with every ten meters, however, more obstacles would make sure to stand in his way. What made him stop on the tracks was when suddenly, a giant fish-like humanoid creature appeared in front of the scar-faced fighter.

"GrowKa!" It lets out a weird snarl.

'What in the name of kami!?' He took a good look at that ugly thing.

Most of its body was green in color but the underbelly was white, as well as having numerous small spikes all over its body. It has two blackfish eyes, a mouth with sharp teeth showing its prominent underbite. Its fins and tails were green too. The water creature then clasps both hands together like it's praying, but one second later it's then shown to make the water around him flow through his hands, forming what could be seen as mini water tornadoes on both limbs It then throws his attack towards Yamcha as a sign that it wanted to fight, blocking his path.

'Oh shoot!'

The guy manages to dash away from the attacks before it can hit him, but they were being positioned in different areas after stopping, creating then water torrents that are either pushing him away or sucking him back, it was weird.

'Damn it! It's going to be harder than I thought!'

With this Yamcha tenses himself and lets out a powerful Kiai from his fist, hoping to stop the wave of small tornadoes. Somehow he manages to get rid of them by punching right through it, using more power than the enemy output. That fish thing was getting on his nerves, he had to keep control of his breath and not waste time with him.

'If you want to do this then I put you away for good!'

Charging up energy from his palm, Yamcha blasts off the sea creature, a yellow Ki-blast that came off his arm like a laser, enveloping his foe before it could do anything else. It soon turned to ashes with one big boom later and it was no more.

'I might have gone a bit overboard? Nah if I keep taking my time not only will it give a chance for anything else here to attack but my breath won't last long either'

Yamcha could feel his body, wanting to breathe again and take off the amount of CO2 from his lungs, but he had to summon his willpower to not let that happen. Now, what was the best way to take off great lengths underwater and get up on the surface? Swimming was an option but being so deep and having things attacking would be troublesome, he needed something to propel him off.

'Oh! I got an idea! Hope this works'

The martial artists start to charge a blue azure like the energy that he had done so many times, but this time, instead of being on his arms like it's supposed to be, it's instead of being channeled on his feet.

'Ka...Me...Ha...Me...HA!'

And just like that the energy from the Kame style signature move propels him up at great speeds, the natural light from the attack illuminating his way, Yamcha didn't know how far he was right now, he just kept pumping more ki for the ride, but the darkness started to become less and less as bioluminescent mushrooms started showing up and the blue color of the crystalline ocean could be seen, signs of marine life springing to the surrounds, becoming sparkling and beautiful. That had to mean he had got away quickly and didn't even notice.

'Awesome! Now this is more like it'

Stopping his blast so he won't be wasting too much energy, Yamcha proceeds to go back and swim at full throttle.

'Hell yeah I'm almost there...just a little more and I can get to the surface'

Unfortunately for him, something else decided to get between his win once more. It showed up so quickly, thanks to a slight moment of his guard being lowered, the guy didn't see it coming and it ALMOST ended up getting his torso bitten off.

'W-WHAT THE HECK!?' He took a look and gasped in the process.

What tried to attack him you ask? Nothing much, just a BIG and MEAN-looking sea creature who is known to be dangerous, it was a shark! But not your average White shark, it was hulking eighteen meters long in length, possessing a maw of sharp eighteen centimeters set of teeth that only the mighty apex predator could have.

'Ngh…'

The entire ride was all about holding his breath while resisting under harsh water environments with high pressure and cold temperatures. He had to fight and now lost some of the air by the surprise of a big fish-like animal that the former bandit didn't see coming.

'Yowza! How the heck is a shark this size here?!' He said surprised at how big and dangerous it looked ' And it even looks intimidating too, but It's just a big fish, it won't cause that much turmoil'

Yamcha didn't know at first but he was pushing through his lungs capacity, it hit a point where as an emergency response from his spleen, fifteen percent of oxygen-rich blood which was held in storage for emergencies was released into his bloodstream giving a sensation of energy. Pushing aside his surprise, the man uses a Kiai once more to push the beast away, it worked so many times already it would work again, right? The shark takes the invisible push but is only momentarily disoriented, showing that this guy was not normal.

'What? Man, did I underestimate it?' He dodges another rush of that thing trying to kill him 'Tch, you damn annoying overgrown sardine!'

Yamcha starts to prepare himself and then... 'CHOU SOUKIDAN!'

When the Megalodon opened its maw showing all of its big and sharp row set of teeth, swimming at full thrust wanting to eat his prey, it ends up instead swallowing Yamcha's signature ki move, but the man ended up adding more power than needed because of its rush to end it, which made a big...

*BOOM!*

The big predator of the sea bit more than he could swallow, which makes him go back to extinction as its body blows up like fireworks, leaving a trail of blood and organs all over the water like a pinata.

'Oh...Oh Geez' He realizes what happened and tries not to puke feeling grossed out 'I need a shower...anywhere but here'

Feeling extremely nauseated, the now covered in shark blood warrior swims the last meters frantically to escape that place before the entrails bring up more sharks, his breath was at the limit after all that, more because of all the shocking, blood over his body, cold water, and pressure it really took a lot from him.

'Ugh! I'm fed up with this now'

The surface was getting closer the more he pushed his body towards it, before Yamcha could notice, the warrior's face was covered by some white blinding light when it touched the glistening water from above. His surroundings took an abrupt new spin as he had finally reached his goal.

Gasps for air frantically "...D-Did I reach the end?"

He was laying down on the white floor of the even whiter void from before, his clothes now completely dry and clean from any liquid or gore, almost like it was all just a dream the fighter was having a few minutes ago. But he could still feel in his body, all the effort that was used not too long.

"You sure did bucko, congratulations! I had a blast watching your performance" Melvin said in amusement while clapping to him.

Still breathing heavily from the experience "Did you enjoy this all along?"

"Did I enjoy seeing you go through the deep sea like a boss? Yes, did I tell you I was going to be watching? Yes!" He said like it was obvious "Don't be dizzy on me now, you accepted this"

"I thought that you would be a little more sympathetic to me...Oh well! At least I got through your little obstacle course!" Yamcha said getting up and stretching.

"Oh I'm sorry, did you want me to be your crutch? I thought you wanted to do this the hard way and train as hard as possible, tell me I'm wrong, tell me you didn't like to go through that deep-sea adventure like a damn pro scuba diver" He said with a smug expression after teasing him.

"W-Well...I guess I did like the high stakes of it all. Made everything wilder'' The scar-faced dude said rubbing the back of his head.

"There you go, isn't it fun when you do something dangerous and amazing but still having half the chance to win or die? Now come here it's time I give you what you deserve " Melvin waves up to him in getting closer.

"Oooh! What is it?" He asked curiously.

"Didn't I tell you what it was?"

"No...you told me close to naught what it was all about before throwing me at the bottom of the sea" Yamcha said bluntly.

"Oh sorry, by all means" The entity then proceeds to put his staff at Yamcha's forehead and says "OVERDRIVE!"

"Whoahhhhhhh!"

Yamcha starts to feel something flowing inside of him, his eyes white-out for a moment as knowledge and skill of a technique unknown to him is imprinted to his brain like magic.

"There we go, oh! I also said that word just for fun I don't say it all the time"

Wow...What was that? I feel...different'' The man looked at his hands, a feeling of vitality to his very being.

"Is that so? How exactly are you feeling?" Melvin asked with amusement.

"I feel energy surging through me but...it feels a bit different, and I somehow feel younger? Does that make sense?"

"Only one way to find out, come on and try powering up, think about that feeling, and slowly reach towards it"

With a nod, Yamcha gets in a stance, slowly taking a few breaths before imagining what was inside his very being...and then starts powering up letting his ki out. His usual milky-like aura that all humans had enveloped the body, but for some reason, Yamcha's energy now had a yellow glow to it that sparkled like electricity. Not as intense as super Saiyan but was still quite astonishing to look at.

"Wow...so this is what I was feeling? It feels great" He said with a smile.

"What you have there is called Hamon!"

"Ha...Mon? What is it?"

"Well, you already know about ki right? But there are all different types of energy out there, what's important is also the frequency and spirit, think of it as your inner energy being shown a new path to follow while bringing along what you already know" Melvin explained.

Yamcha pays attention to what he is saying, there were indeed different types of ki such as the Saiyans transformation or amalgamations of ki into one like Cell.

"Through self-controlled respiration, this technique can produce energy manifesting as ripples throughout the body, which propagates through the bloodstream and rest of the body. It can also affect non-living things. An object charged with Ripple energy will have one or several attributes enhanced by the energy, making it a more effective tool, or weapon, but liquids are the best conduct for it. It can show itself as electricity-like sparks the energy it's said to resemble the sun"

"Eh?! The energy of the Sun? But how can I even wield a power such as this?" The martial artist was feeling surprised more than before.

"Don't get your hopes up kid, this is not some mighty cheat code. Is only similar, due to its identical nature to the positive energy of the Sun, hamon's primary uses are to heal various wounds or ailments, and combat creatures that are weak to sunlight

"I see. So it can be used to heal allies, thats interesting, but who would be weak to sunlight? Vampires? That sounds kinda cool when I think about it though" Yamcha said even though their friends didn't meet that many enemies with the undead characteristic.

"Now! If you were just a normal over the hill guy who just learned this, then by trying to use it on a normal human, it would end up making said person experience a feeling of pins and needles before fainting. Similar in nature to symptoms experienced after prolonged exposure to the sun's rays" Melvin explained in great detail.

"Understood. So it's useless against normal people" Yamcha bluntly said

"Eh? I wouldn't call it useless, after all, your ki control training made you have superhuman characteristics, so think of this as a small bit of a powerup or support skill that will sting your enemies with each blow like a hornet, its cooler like that" He said almost like it was offended that this move was being looked down.

"Hmm. if you put it that way, maybe I can use this as a way to turn the tables around, you never know" Yamcha thought about it.

"Yeah man, only focusing on strength is boring. This is how the real fun starts" Melvin went back to his happy beat.

"But it basically just powers up my moves. This technique is reliant on strength" Yamcha kept going.

"No...it doesn't. Your power level it's still the same, it didn't get you anything like a TEN TIMES boost of ki or anything, some may think that Hamon is pointless when not used against its main type of enemy, but it has some real kicks to it"

"Oh really? Like what exactly?"

"Well for starters, all lifeforms in the world need sunlight to survive, this may not allow you to beat a Super Saiyan but the constant pratice of it, will allow you to slow down the aging process, not completely but you will feel the body brimming with life force"

"No way! For real? I wonder if Master Roshi knows this, he has been around for quite some time already by what I know back in the day.It would be better to grasp this new power as much as possible first" Yamcha said, feeling eager.

"I gave you the power, now it's up to you to use it at its full potential. Because You and I are going to have a lot of fun together, this is just the beginning hahaha!" Melvin laughed like a madman.

"Eh? And what is that supposed to mean exactly?" Yamcha had to ask.

"More challenges, more Powah for you! And More everything! Think of the possibilities, Oh I get so excited thinking about it" He said while flying around him in a spin.

"Oh, man! That sounds like it will be too wild, but hey I'm already on top of this ride! I'm in, all the way now" Yamcha said giving a thumbs up.

"No takes back kid!"

"Yes Sir!"
