Chapter 5: Paving The Road to Hell

Entering the Uchiha Clan Head's dwelling invoked a lot of good and familiar memories for Obito. Every week, Obito loved to stop by whenever he had some free time to teach Itachi a new trick he learned in the Ninja Academy. While Obito wasn't a good teacher by any stretch of the imagination, Itachi was intelligent enough to fill in the missing gaps in order to understand what Obito was trying to teach him. Everything from shurikenjutsu to using chakra to augment taijutsu was taught to the young heir. This allowed Itachi to reach the level of genin at the age of four before he was allowed into the academy for two more years - during wartime standards.

Unknowingly, Obito cemented himself as a wise teacher and an inspiring person that Itachi wanted to also be. Itachi would tell his immediate family about Obito's passionate dream of becoming Hokage, who would then spread the knowledge to the rest of the clan. By doing so, the whole Uchiha clan knew about Obito's dream and was willing to support Obito when the time was right for him to become Hokage.

They reasoned that if Obito could teach Itachi how to do a successful Katon: Gokakyu no Jutsu (FIre Release: Great Fireball Technique) to pass the Uchiha Rite of Passage at such at the unprecedented age of four, then Obito had the potential to lead Konoha into greater prosperity with the Uchiha at the helm. While many believed that Obito was not a prodigy, he had the potential to be at least an A-rank shinobi considering the amount of passion and drive he had. Coupled with his massive creativity, as seen through his many pranks at the Hyuga that the Uchiha secretly approved, Obito had the clear markings of a jutsu creator.

Thus, when Kakashi received Obito's Sharingan in the original timeline, many were outraged over the death and desecration of a well-known and loved individual in the Uchiha community.

But Obito, and now Naruto, didn't know any of this. Naruto only knew that he was warmly welcomed into the clan head family since he did a fantastic job teaching the future clan head. That is why Naruto wasn't surprised when he found himself greeting by a familiar calm face that subtly expressed happiness, Kagami Uchiha.

Noted as the grandfather of Sasuke, Kagami was best remembered in history as the Teikoku Hinoarashi (Imperial Fire Storm) of Konoha during the First Shinobi World War. Ranked as an A-class shinobi, his impressive fire release techniques including the awe-inspiring Katon: Goka Mekkyaku (Fire Release: Majestic Destroyer Flame) which allowed him to annihilate swaths of shinobis and played a crucial role in destroying key enemy formations. He was also remarked as one of the few Uchiha's who was the closest to reaching the level of the Madara Uchiha before he was forced to retire early at the age of fifteen due to a leg injury.

"Kagami-sama." Naruto bowed to the Uchiha as his voice took on a warm inflection at the sight of Obito's surrogate father figure.

"Obito, I'm glad you're back. Many missed your… bolstering presence." Kagami replied with a tint of mirth. "Some more than others."

"Indeed Kagami-sama. The little ones were a little more excited than usual." Naruto agreed, as he remembered being swarmed by many Uchiha kids who were just as happy that their older brother figure survived the clutches of death. Naruto was really surprised by how much the Uchiha loved Obito considering Kakashi-sensei told him during the war that Obito was isolated from the rest of the clan. Which begs the question, a divergence in the world or Kakashi's inaccurate observations?

"Oh? I was refering to my daughter. Word of your death saddened her greatly until you came back." Kagami said friendly before it slowly turned wrathful. "Which begs the question. Why haven't you visited her earlier? You were here for two whole weeks and I have not seen one hair of you since. Would you care to explain? Hmm?" By the end, Kagami's tone turned arctic as his activated Sharingan drilled holes into Naruto.

Naruto let out a gulp as he was quickly trying to find an excuse not to piss off the Uchiha. Obito's memories involving Kagami's wrath never ended well for Obito at all while Naruto was really freaked out by how vengeful the man could be to his enemies which made his childhood pranks look like harmless parties. "Um...I-I...uh...was…doing..."

"Was doing…?" Kagami repeated mockingly as he folded his arms as the crimson dojutsu continued to stare at the trembling figure at the entrance of the house. "Tell me Obito…" the man said as his eyebrow was visibly twitching "was that civilian at your house occupying so much of that useless space in your head you called a brain? Do you have any decency to act like a mature Uchiha shinobi when you have guests?"

"I…" Naruto was flabbergasted by how Sasuke's grandfather came to a far-fetched conclusion that involved him and Tsunami. But before he could answer, someone else did.

"Father, could you please stop being mean to Obito-kun? I'm sure he was just busy." A female voice cheerfully broke through the tension between the two males.

Naruto, thankful for the save, turned to see a female Uchiha striding confidently towards them. Mikoto Uchiha. Dressed in a simple navy blue shirt and shorts, the female cut out an imposing yet beautiful figure that highlighted all the right curves to Naruto's secret delight. If Tsunami was the cute yet voluptuous farmer, Mikoto was the elegant female kunoichi with a hint of aristocratic maturity. Armed with firm a pair of C-cup breasts and slender long legs, her glowing coal-black eyes bore into any male who was lucky enough to receive her attention. Wow. She's a ten alright, maybe an eleven or a twelve or a freakin thirteen! I can't wait until she gets older...

When that thought passed through the time-traveler's mind, Naruto mentally banged his head on the wall repeatedly for checking out Sasuke's married mom. Oh god, Ero-sennin will not live me through this one. Thank Kami that he is in heaven right now. At least, back at home he is...

"Nee-san!" Naruto reflexively replied as memories of Sasuke's mother acted as a surrogate older sister for Obito.

Mikoto Uchiha walked up to Naruto and gave him a tight hug. Doing his best to hide his embarrassed blush when he felt her assets on his chest, Naruto reciprocated the hug while mentally noting that he was taller than her by a couple more inches.

She must have noticed that as well when an appraising look crossed her face. "You got taller Obito! Have you been drinking your milk recently? I thought you would never sprout up like a tree." She said mischievously as she brought her hand up to her head to compare how tall Obito was to her.

Naruto grumbled about how mean she was. Stepping back from the hug, Naruto smiled at Itachi's mother. "It's good to see you again nee-san. How's Itachi now these days?"

"He is doing great. He was recently thinking of picking up kenjutsu after seeing you wave a sword around two months ago."

"I was not waving a sword around! I was practicing my katas!" Naruto pouted. He mentally laughed that Obito was trying and failing miserably at trying to act "cool" like Kakashi. At least, I did a better job wooing Sakura! At least I think...

"Really?" Mikoto said incredulity. "It looked like you were trying to chop your arm off."

"Moh! I was practicing a new form that I learned! It wasn't my fault that I turned your bushes red." Naruto winced at how weak that argument was. Why the hell am I acting so childish? Does Obito have that much of an influence on me? This bears investigation...

"Indeed, it's the sword's fault. I'm sorry for not realizing it sooner!" She said sarcastically. Before Obito's personality was able to dig Naruto into a bigger hole, his "disciple" saved him.

"Kaa-san! The food looks like it's on fire!" Itachi yelled out from inside the house. Realizing that food was still cooking on the stove, Mikoto immediately dashed into the house as she tried to save her food for lunch.

She yelled back at Naruto. "Sorry Obito-kun! I'll talk to you later. I'm just glad you're safe."

"Bye nee-san. I'll be stopping by to teach Itachi in a couple of days." Naruto waved at the disappearing female.

Kagami let out a small snicker at the drama between the two Uchihas. Letting out a loud grunt to attract the attention of Obito, he said, "Anyway, I called you here Obito because the elders wish to discuss what you have recently gained." His eyes flashed red quickly before turning back to coal-black.

Naruto, understanding the topic, nodded his head. "Now?"

"No." Kagami said as he handed him a scroll. "This has all the instructions for the location of the meeting tomorrow at midday. Make sure to dispose of it."

"Understood Kagami-sama." Naruto said as he pocketed the scroll in his kimono.

"Will you join us for lunch?" The A-rank shinobi questioned.

"I apologize, but I have other things to attend to." Naruto said earnestly.

"Acceptable. Have a great day Obito-kun." Kagami smiled before he slowly walked into the house. Then he turned his neck back to stare at Obito. "I trust you will tell no one of this. Correct?"

"Huh? I'm sorry, did we say something Kagami-sama?" Naruto replied innocently as he quoted from his sensei that was currently not his sensei.

Kagami just shaked his head in amusement and continued to head to the kitchen for his burnt lunch based off the smell he was smelling.

Leaving the house, Naruto looked at the sky and noted that he had a couple more hours before dinner. Mentally, he drooled at the delicious stew Tsunami was going to make. He was very happy at the warm feeling of coming home with someone making dinner for him everyday. I think I should take Tsunami out for dinner soon. It shouldn't be healthy staying in my house all day and I really need to thank her for all the good food she made for me. But where should I take her? Hmm… Ooooh! I haven't had some ramen in a long time! Maybe I should take her out for Ramen Ichiraku.

Mentally envisioning the delicious ramen that he was going to fill up his stomach with, Naruto let out a true relaxing smile. Man, it feels great to be home. Instead of walking back home, Naruto went into the opposite direction where the Uchiha Market District was to find a particular shop based off Obito's memories and grabbed a quick dango snack along the way.

Finding the simple shop, Naruto opened the door to see racks upon racks of various weapons from the simple kunai to exotic weapons like the hook swords. Looking around, he found the individual he was looking for.

The old man grunted as he walked out from the back with a box full of shuriken. Putting the box down onto the counter, he looked up to see a familiar face. "Obito!" The old man said jovially as he walked to Naruto. "Its great to see you again. Thank you for helping my wife out yesterday with the groceries."

"It's no problem Koharu-jiji. Anyway, can I use the forge in the back? I have a project I want to complete and I already have all the materials ready to go."

"It's all yours boy." The elderly Uchiha patted Naruto on the shoulder kindly. "You helped us so much over the years so it's the least I can do. But make sure to holler if you need anything."

"Thanks Jiji." Naruto bowed in thanks before he headed off to the back of the shop where he can start building his favorite weapon that he was missing.

An Uchiha forge was a unique forge that could not be found anywhere else in the Elemental Nations. Built to withstand high temperatures, this forge allowed Uchihas to utilize their strong fire nature to build weapons out of tough chakra metal. Furthermore, the use of the Sharingan allowed them to accurately pinpoint the minor flaws in a weapon effortlessly. This caused Uchiha-made weapons be always of high quality and very expensive. These weapons are so expensive that 34% of the income the Uchiha clan makes comes from supplying basic weapons although that number has recently risen to 72% with the war going on. That is why every Uchiha must learn how to use the Uchiha forge when they reach chunin.

Obito, and now Naruto, was no different. Already understanding all the various tools in this very heated workplace, Naruto used Kamui (Authority of the Gods) to bring out all the supplies he needed from his own personal dimension: 5 pounds of sensitive grade A chakra metal, 5 gallons of extracted blood, and a paint brush.

Wiping the blood that was leaking from his right eye, Naruto used a kunai machine cutter to start cutting the chakra metal into the right amounts. Then, he spent hours to flatten the pieces with the hammer as he lightly infused Lightning chakra into the metal.

Once Naruto was satisfied with the pieces of metal pounded, he poured out the gallons of his blood into a huge metal bucket to cool down the metal. His own blood was used as a medium to allow Naruto to easily direct as much senjutsu chakra as possible to the boiling blood and imprint his own chakra signature onto the weapon quickly.

Naruto ignored the little part of his mind that he was going to bring back a weapon that would be the cause of thousands upon thousands of deaths. Considering how easy it was for someone to use this weapon with little training, Naruto felt like he was going to condemn this world to the ugly and destructive warfare seen in the Fifth Shinobi World. Taking a deep breath, Naruto would stand resolute in his decision. Pulling the metals drenched in blood, he used his Sharingan to inspect it for any possible fractures.

Its for the sake of Konoha. Naruto reasoned to himself. So they will not have to suffer again. Grabbing the hammer, he pounded onto the metal. Yes...it's all for the greater good.

Unlike the basic manufactured chakra rifles in Naruto's home dimension that shot spheres of chakra, Naruto was making his personal rifle that he built himself.

Griefed with the death of Sasuke, Naruto successfully pleaded to Kakashi to teach him the Chidori (Lightning Release: One Thousand Birds). Despite all that effort, Naruto could not utilize the S-rank jutsu in battle effectively since he never had a Sharingan to use it with. Then, he tried to recreate all of the other Chidori variants Sasuke created since they didn't require a Sharingan - Chidori Nagashi (Lightning Release: One Thousand Birds Current), Chidori Senbon (Lightning Release: One Thousand Birds Senbon), and Chidori Eiso (Lightning Release: One Thousand Birds Sharp Spear) - but failed considering he didn't have the needed chakra control in relation to his chakra reserves.

However, Naruto was still very determined to remind himself of Sasuke's sacrifice by implementing some type of Chidori into his fighting style. Then he had an idea: if he couldn't do chakra control, make someone else do it for him. Using the similar ideology of using Kage Bushin no Jutsu (Shadow Clone Technique) to create the Rasengan (Spiralling Sphere) and their subsequent variants, Naruto used the shape barrel of chakra rifles as a way to achieve a higher level of chakra control.

After much trial and error, Naruto could proudly say that he found a unique way to mimic the Chidori Eiso (Lightning Release: One Thousand Birds Sharp Spear). But also, he increased its killing potential triple fold by magnifying how far he could use the weapon to pierce an enemy and its piercing power. Kakashi remarked to him that he made Chidori Eiso, an A-rank technique, become Chidori Reza (Lightning Release: One Thousand Birds Laser), a S-rank technique, and that Sasuke would be proud of Naruto for greatly improving one of his own jutsu creations.

"Welcome back to the world…" Naruto mumbled to the completed weapon laying on the table, "Mikazuchi…"

Wiping off the sweat that was accumulating on his forehead from working nonstop for five hours, Naruto looked his newest masterpiece with proudness and a hint of nostalgia. Standing at 125.7 centimeters in length, 10.1 centimeters in width and 32 centimeters in height, Mikazuchi weighed in at 13.2 kilograms. She featured an angular geometric design and metallic casing that included a stock, a firing grip, a stabilizing firing grip, a scope with a 4x zoom magnification, and a channel matrix barrel (Halo Light Rifle).

Marveling at the elegance and beauty of the deadly killing machine he had created, Naruto infused a sealless Chidori in his right hand when he gripped the handle. The absorption of pure senjutsu chakra during her construction process allowed his Chidori lightning to effortlessly flow through the weapon's chakra channels seamlessly and lighted up the channel matrix barrel with a bright red glow of electricity.

Naruto let out a chuckle that progressed into laughter when he considered how quick and easy it is to make a weapon that would change the face of the Elemental Nations permanently within the next decade or so.

"Obito-kun, are you alright in there? I heard some loud noises that sounded like birds chirping. Do you need help in there?" Koharu asked.

"No Koharu-jiji." Naruto replied back as he gazed at the weapon foundly that felt so comfortable, so right, in his hands which spoke volumes about how much he used his chakra rifle. "I don't need any help…"

"Alright then. Make sure you show me what you made in there when you're done. I can already tell it's going to be something great considering that I can hear how happy you are in there from outside the shop."

"Indeed Jiji. She is something great. Indeed she is." The Uzu-Uchiha replied with a tint of sadness. She's gonna to make the whole world be dyed in blood. He thought guiltily. And I'm going to make her even stronger than her last iteration. Powering down the rifle and grabbing the paint brush, he dipped its tip into the pool of blood before writing tiny characters on the weapon. Hmm...maybe I should add a camo design on her later… She seems kinda bland at the moment. Orange perhaps?

A/N:

Thank you so much for all the heartwarming reviews. Your support is driving me to continue writing chapters quickly!

Anyway, I am surprised by how many of you want an older girl harem. So I decided to tease you guys on our next (obvious) harem member. However, you guys won't see much instant romance develop between Naruto and Mikoto since I am trying to not fall under the harem cliche of: girl A sees male and immediately falls in love for X reason. My goal is to slowly develop the romance aspect between Naruto and various girls over a longer period of time. So, I'm sorry if this isn't the type of harem story you were looking for.

Another thing that many of you brought up that I am trying not to do is make Naruto/Obito too overpowered. My plan was to establish him as a mid-rank S class shinobi who could easily kill 98% of all shinobi but he won't be able curb stomp everyone. At the present moment, he would be able to somewhat fight Madara equally in his prime in the right circumstances but he has no hope of winning against Madara's Jinchuriki Form. Adding the chakra rifle in the mix may make him seem way too strong, but it is a precision weapon used only for long range engagements. Shinobi currently fight in close quarters combat 99% of the time so Naruto won't be using the rifle all the time.
