Sorry for the slow update everyone, I was thinking of the future plot of the crossover and had no time to update this yet.

So, let's go!

At the guild:

The trio on their original outfits are having breakfast. CE chose bread, eggs and milk, zombieman have black coffee and meat, while saitama had steak and some orange juice.

"So why did you declined sharing on how to make guns?" Saitama said, with a smile on his face since it's been some time when he had steak.

"It's dangerous, might fall into the wrong hands" CE replied, sometimes he was wondering if he's just acting dumb or if he's really dumb.

"Yeah, it's better not to share them. Besides, it should exists here in the first place" ZM followed, lighting up cigars in his mouth.

Saitama didn't even listen, thinking of being rich by having a gun business.

After a few minutes, GS and his party entered the guild.

CE and ZM walked up and greeted them.

"Good morning guys! How are you today?" CE happily asked.

"Good morning CE-san, we're doing good" Priestess also replied with a smile on her face.

"I heard you got roughed up from the water port incident" ZM said, while the rest of GS party nodded, it was really a tough quest.

"Let's talk about it on the second floor" As they ordered food for the upcoming feast.

"I'm also interested in GS-san, you're fairly knowledgeable in chemistry" CE said, clearly curious where or whom he learned those things from.

As they feast and put themselves on ease, the group started sharing information about their previous experience.

"So, whom or where have you learned chemistry?" CE repeated to GS.

"I learned it from a lot of things" he replied, his stoic voice still remaining.

"So where did you learned how to deal with goblins and why them exactly?" CE followed up.

"I learned from my previous master. As for why, because they're goblins and I have to" He followed up, he gave the last sentence an emphasis in a much higher tone.

ZM, CE and CB felt the tension in the air. They knew that feeling very well, when a man had an unpleasant past.

"Having a goal is good and all, but what about after?" Saitama questioned. Somehow GS reminds him of his student Genos, who had a great spirit of vengeance and hatred against the mad cyborg that destroyed his town, took his family's life away as well.

GS also had similar attitude to Genos, they doesn't care about anything that is not related to their goals, resulting in their very serious and awkward personality.

There is a few second of uncomfortable silence. GS couldn't say anything, even he himself doesn't know on what to do after the goblins had been obliterated.

"Ummm, it's fine if you don't want to answer goblinslayer-san" CE said, while giving saitama a sharp glance for him being blunt and not reading the atmosphere.

"That's right GS-san" Priestess tried to intervene as well, it seems like someone stepped on a landmine.

Meanwhile, HEA decided to ask saitama on why he had to ask that sensitive question. Even if he's working with them, they must have some sort of privacy too.

"Why do you have to ask that, saitama?" HEA asked, clearly annoyed at the situation.

'Well, it's going to exceed the 20-word limit but here I go' As saitama prepared his mind, he doesn't really want to see another Genos, due to him having real connection now with the cyborg.

"He reminds me of my disciple, vengeful and serious. I don't want him to become like him. " He replied, CE immediately knew what he's trying to do.

"You had a disciple? That's shocking" Mage dwarf said, lizard priest also nodded since Saitama's not the kind of person to have a disciple.

"Yeah. Anyways, he's very awkward and hard to socialize with. That's because he had an old enemy to defeat, a cyborg who destroyed his town and took his family's lives. Most of the time he's reckless and getting destroyed a lot because of his vengeful personality." Saitama replied.

"The feeling that you can't do anything since you're powerless, even I felt that a long time ago. You had a goal you must achieve no matter what, but that doesn't mean you will destroy yourself in the process." He followed up. Everyone felt that line, the thought is resonating in their hearts.

ZM and CE felt powerless against garou. GS felt powerless as his sister got raped and killed by goblins. Priestess also had the same experience with her first party. Saitama also felt that when he's being bullied as an outcast in his school life.

There's a few seconds of silence. The baldy's words are hitting their very soul. After some time, CE decided to change the topic, to make the atmosphere not awkward.

"So what happened to your journey at water town?" He asked hoping that it will lessen the tension in the air.

Thank goodness, the awkwardness is slithering away. GS's party told them what happened. Like how they encountered a goblin champion, nearly being defeated and how they triumphed in the end thanks to GS.

They also shared on how they dealt with the eyeball monster and the horde of goblins after that. They also told the trio on how amazing GS tactics is.

"Ooh, so you used flour to make an explosion? That's quite good. I made a similar tactics in the MA base." CE said.

"Yeah" GS replied, his voice is back on how it used to be, he tried to accept the baldy's words and it calmed him down.

"We also found a large mirror, it is being said that it is used as a teleportation gate in the past." HEA said, this earned ZM and CE's attention.

"Do you have it in your possession? Why didn't you inform us using your communicators?" CE questioned.

"Oh, that's because we're busy and tired so we kinda forgot about it" The priestess replied, with a cute goofy smile on her face.

"Nevermind, I'll check it later anyways." He replied, as he looked southside and saw Heavy warrior training 2 newbies.

"So what happened to the training courses idea?" Lizard priest asked.

"It is currently under review. They'll tell me of it's done though" he replied.

"Hey, how about we do some sparring match?" As he pointed one of his index finger outside, which shows heavy warrior training 2 newbies.

"Sure, it's a great workout and a way to digest food" ZM replied, he needed to make sure that his skills are not getting rusty.

After a few minutes, the group went outside the guild and joined HW and FK in their session.

"Yo, care for a little sparring?" ZM asked heavy warrior. ZM pulled out the 2 machetes that he had on his back.

"That sounds fun, care for a two on one?" Female knight said as he stood beside heavy warrior.

"It's my honor to fight an immortal, I can finally go all out." HW smiled as he and FK took their fighting stance.

"The win condition will be when a side got unarmed or when faced with inevitable defeat " CE followed up. The warriors nodded.

This gathered attention to the people inside the guild like spearman and his partner witch. GS and his party is also observing the incoming duel. As well as the other civilians and adventurer who's interestedin the fight.

Meanwhile, everyone started betting on their winning team. 2 silver ranked adventurer vs an immortal Gold ranked adventurer.

"This is going to be great! Want to take a bet on who's the victor?" Rookie warrior said to his partner which earned a sharp glance.

"That's our earnings for today. So don't?" She replied, the battle is interesting though.

The bets are even. Even if ZM is immortal, his two machetes can be disarmed by an experienced party of two. While the two silver ranked adventurers can be defeated by ZM's immortal body advantage and skills.

The battle started, ZM made the first move and dashed toward the couple. The couple was surprised at his speed but Female knight activated her [block] skill before the machete could strike HW's greatsword handle to disarm him.

Zombieman was surprised but kept his composure. Then he adapted a low stance to tackle FK on the ground to pin her down and remove her from the duel, only to be caught off guard by HW's swing and got his hand slashed. He quickly pulled down his head and bitten the machete's handle, then he stepped backward to make space and reset on what to do next.

"Ooh, they're trying to disarm ZM, since they couldn't defeat him by killing him. Good decision!" Spearman happily said, earning an agreement with GS's party as they seen him regenerate from a bloody corpse.

"Indeed, the duel can go either way. ZM has his regeneration and skill while the other two had their experience, compatibility and numbers" Dwarf mage said.

'So they decided to disarm me, this puts me in a disadvantage. However, I can turn that to my advantage' ZM thought as he lunged forward again.

The couple noticed the difference in speed ZM had, he was far slower than before, but they're not sure on what he's trying to do.

FK went to the front, guarding her partner from ZM's assault. ZM attacked her shield consecutively to no avail, FK is wondering what his plans are.

The audience also noticed this and kept questioning why ZM attacked FK's shield of all things to attack.

Heavy warrior didn't think about it through and slashed Zombieman's whole left arm, while FK chopped ZM's head off. The couple smiled, they disarmed one of ZM's machetes and removed his sight from the battlefield.

Or so they thought.

ZM kicked his falling hand upwards into the sky, which surprised the couple. Then zombieman tackled FM when she's still trying to process on what happened.

He then quickly placed his machete on the female's neck, which made her unable to continue on the duel.

HW made a 3 meters distance between him and ZM. Now, it's only 1vs1 between ZM and HW.

'The bastard lured us' Heavy warrior thought, as he glanced over to FK's defeated form on the ground.

"If what I noticed is correct, ZM made the couple lower their guard down by looking like a fool by as he attacked Female knight's shield. Then he kicked his severed arm unexpectedly to make them lose concentration and took advantage of it." Lizardman said, the others also agreed to the explanation.

Zombieman grabbed his severed arm that's falling in the air and threw it in a very fast manner to heavy warrior, however HW used his [Heavy Air slash] which pulverized ZM's severed arm and splited ZM himself in half.

Zombieman was now disarmed of one of his machetes as it touched the ground.

HW quickly dashed forward as fast as he could and tried to disarm zombieman, but it was intercepted by ZM's other machete.

Meanshile, zombieman's whole body had regenerated. The two tried to overpower each other, ZM using one hand on his remaining machete while HW was using two hands on his greatsword.

ZM disengaged his machete and let HW to fall due to the force that he's exerting and made him lose balance. Without further ado, ZM disarmed HW by kicking his greatsword off his hands when the latter was falling and won by placing his machete on his neck on the ground.

The greatsword flew towards child emperor. CE then catched the greatsword by his handle and placed it on the ground.

"Now that's a great battle. It is not everyday you can see something that intense." Spearman said, as he clapped his hands

The audience also did the same, it was quite a duel to see indeed.

"Here's your greatsword" As child emperor lifted up the greatsword and gave it to Heavy warrior.

The crowd is dumbfounded on this kid, he just lifted a greatsword that's bigger and heavier than his whole body with one hand!

"H-h-how can you lift this with one hand?" HW asked the kid, the kid only raised an eyebrow in response.

"You think I'm physically weak? I'm twice as strong as a 7 meter bear." CE replied.

"That's a good exercise, thank you." ZM said as he helped female knight and HW to stand up.

'That's an exercise to him? We gave it our all!' Female knight and Heavy warrior thought in unision as they sweat a little.

"Yeah, I'm holding back as much as I can. I don't want to injure you guys in this sparring practice" ZM followed up.

The crowd is also surprised that the gold ranked adventurer is still holding back on feats that he showed on the battle.

"So zombieman, I want to test some gadgets that I created using this world's materials. How about you test it with me?" CE said with a serious glance to ZM. He wanted to make sure that he's not falling behind.

"That's the look. I'll be serious this time" ZM responded while the others made space for them in the middle of the field.

"Ooh, an all out battle of gold ranked adventurers? I still have a long way to go!" Rookie warrior shouted, he was hyped up on becoming strong like those gold ranked adventurers.

"Yeah, no kidding. We still had a long way to go" Heavy warrior said, as female knight and Spearman nodded with the idea.

Well that's it guys! I'm not good at making action scenes, but I clearly remember how ZM fights for most of the time. Even thoigh he needs to hold back a lot, he still have A-class level stats just like child emperor.

Next up will be CE vs ZM.
