20 Ultimate Training

Early in the morning, at day break, a very foul smell stirred Kakashi up from his sleep. Still wanting to sleep more, he began to have this inner debate in his mind if he was having a nightmare of Naruto's outburst.

He turned to face the other side of his bed, trying to steer away from the smell but the foul smell increased in intensity.

"Wait, smell?" A nasty thought occurred to him…What if?

No way.

He instantly jumped up, and came face to face with Naruto's embarrassed face, who didn't expect to see his sensei particularly stark naked in his upper half.

I totally forgot to lock his room door!!! Kakashi said in his mind.

"What do you want, Naruto?" Kakashi asked as he reached to the side. He had kept Sakura in his room last night and she was still snuggled under the blanket next to him. 

"I'm so sorry sensei!" Naruto screamed, holding his behind and releasing soft pops of foul air. 

Kakashi squeezed his face, and coughed. He wanted this future fat kid to go away. 

"Why did you barge into my room?" He asked, holding his breath. 

 "I needed medicine, Kakashi-sensei! My stomach, it hurts real bad! I was out in the bathroom all night… Who would've thought that your delicious food is so powerful? This even makes me a little fearful of eating your food everyday." Naruto replied, still now realizing that there might be someone else in bed with his sensei. 

"You could've gone to Tsunami! What made you think that I had medicine with me?!"

"I thought you would, since you carry all those stuff with you, Kakashi-sensei!"

Suddenly, the door opened, and Tsunami slightly entered the room, wondering what was going on. It was then that she spotted a bump under the covers next to Kakashi. She instantly knew what was going on because… she found Sakura's clothes in Sasuke's room, and Sakura didn't come to sleep in her room… 

She connected the dots and sighed before leaving quietly. 

"You little…." Kakashi muttered under his breath, before scrolling through his System Storage and buying some modern stomach pain pills. He handed it to Naruto and gestured for the brat to leave. He just wanted the stink bomb to disappear. 

"Thanks, Kakashi sensei!" Naruto smiled brightly before taking the meds and ran to the kitchen to get some water. 

"I think I should just increase the calorie and decrease the quantity and quantity of the food," Kakashi muttered as he purchased some air purifying spray to spray the room. 

"Thank god you have those things…" Sakura muttered from underneath the blanket. 

* * * *

Later that morning, Kakashi and Sakura came down to the dining area and everyone was seated, except Old man Tazuna, Inari, and Sasuke. Sakura had found her clothes in Tsunami's room, and she knew that the milf found out her secret. 

On the table, Naruto was having seafood ramen for breakfast, and Kakashi couldn't help but want to pass on the food again. 

"Good morning, Kakashi-sensei…" Said Naruto, grinning. "Your medicine really helps–" 

"Shut it. Just don't come near me if you want to pop. Next time, I'll just stab you with a kunai." Kakashi squinted at Naruto before going to sip some water. 

Naruto froze, and dug into his ramen. Though, he felt slightly guilty that he approached Kakashi. 

When he thought about the whole scene again, though, he felt that something was amiss… So what was it? Maybe it was because Kakashi's body bulged a bit more under the covers…? Hmmm? 

… 

An hour later, they arrived at the training ground: Kakashi, Sakura, Naruto, and even Sasuke. 

Sasuke had woken up while feeling pained, but he was elated when he figured out that Kakashi had helped him awaken his two tomoe Sharingan! It was at this moment that Sasuke realized why Kakashi had treated him so badly… and he thought that Kakashi must've known a secret of the Sharingan and just didn't want to explain his good deeds… 

But fuck though, Kakashi really is a psycho. Particularly because Kakashi even dared stomp on his most valuable asset, his Uchiha dick and balls. 

Overall, this is Sasuke's evolution of Kakashi – he is a good psycho. 

So instead of sticking with Kakashi and his two teammates, he opted to go train by himself with his Sharingan and he left the group. 

Naruto and Sakura sat on the ground, their legs locked together. 

"Alright you two, we won't be learning Ninjutsu today."

"Huh?" Naruto and Sakura chorused, giving each other weird glances.

"How else are we supposed to get stronger?" asked Naruto, folding his arms.

"The main aim of this training is to make both of you strong enough to defeat Zabuza by yourselves. Our training is based on that, and I've come up with the best solution to boost your powers," he replied and pointed at the sack on the ground. 

"We can't beat Zabuza without at least learning a jutsu," Sakura tried to argue. She wasn't comfortable with the idea. However, she has some expectations from Kakashi… she did all that stuff for him after all. 

Kakashi grinned and summoned his sack of guns and ammo. 

Naruto and Sakura watched in awe as he pulled out two long carton boxes and handed each one to them. They gave him a confused look.

"Go on, open them," He said and folded his arms, watching them intently and grinning.

They opened their boxes, and what they saw made their jaws drop in surprise. They looked up at him.

"What is this?" Naruto asked.

"It's a weapon. A special kind of weapon," said Kakashi, still grinning.

Naruto laid his eyes on the weapon in the box at his feet. It had an angular design that conveyed a sense of lethal precision. It was black, seeming to absorb the sunlight that shone on it.

He traced the contours of the weapon with his fingertips, before carrying it carefully out of the box. It felt cold and metallic beneath his palms. His hands started shaking.

Kakashi's grin got wider as he bought a pistol from the System Shop, making it appear on his hand. Naruto's expression was his reaction when he had to hold and see a gun for the first time.

Sakura looked on at Naruto, surprised at how carefully he was handling it. He was always so goofy and carefree. Now his face looked solemn. She gulped in air and laid her eyes on hers.

It was black, just like Naruto's. The only difference was that it had some rather intricate designs, which created an aura of power within her, as she carried it from the box carefully. She smiled instinctively and stood up with the gun striking a badass pose.

Kakashi released a chuckle as he watched the two. 

"What are these?" asked Naruto, keeping his own weapon back in the box. Sakura gazed at him.

"A new scummy weapon used in wars."

"A new weapon?" asked Sakura, her eyes widening.

"No, I'm sure there's some similar but underdeveloped weapons of this type somewhere right now. However, these are highly developed ones currently available only to me." Kakashi explained as he popped out the mag from his pistol and checked the bullets. 

"Why do we even need this new weapon?" Naruto asked, scratching his head as he stared at Kakashi. He couldn't understand why they can't just keep using kunais and shurikens. 

"Because it's stronger and uses minimal effort," Kakashi clipped the mag back into his pistol and pointed at a nearby tree since it was full. 

*BANG!* 

A loud shot off and a bullet flew to the trunk of a nearby tree. It was rather destructive and bore a hole into the wood. 

"?!?!" 

Naruto and Sakura were both shocked by the loud noise and the damage on the tree. Their kunais and shurikens can also pierce, but they had to put in some effort… However, Kakashi seemed to have done it effortlessly. 

"This weapon is called a gun, and it can deal the same amount of damage within seconds." 

*BANG!* *BANG!* *BANG!*

Kakashi said as he shot the pistol again and again like a gangster. 

Naruto and Sakura's jaws dropped lower and lower, looking at their own guns and comparing them to Kakashi's. His was small, and it could already do this much… What about theirs? They wondered. 

"As you can see, my gun is small and shoots slowly." Kakashi said as he threw the gun into his System storage. 

"That's slow?" Naruto asked, baffled. 

"Yes, your gun is called a submachine gun. It can shoot 12 shots within one second or around 750 shots per minute." 

"WHAT!?" Naruto and Sakura both exclaimed in shock. They couldn't believe what Kakashi was saying. 

"Yeah, dattebayo, Naruto." Kakashi sneered at Naruto as he picked the kid's gun up and shot the tree. 

It went… 

*DUDUDUDUDU* 

And the tree became semi mutilated within seconds. 

Kakashi then continued to explain. "This is harder to control and aim, but Naruto…" 

Kakashi gave Naruto a deep look and continued: "Imagine if you make 1,000 clones and all of your clones shoot at your target all at once. No matter how shit you are at shooting, your enemy will not be able to escape." 

:O 

Naruto was shocked when he heard this. If he did exactly what Kakashi says… doesn't this mean that he will become an invincible Shinobi as long as he has Kakashi's weapon!?!?!?!? 

"YEAHHHHH!!! I LOVE YOU, KAKASHI!!! GIVE ME THE GUN!!! I WANT TO GO TRY IT OUT!!" Naruto screamed and rushed up to grab his gun from Kakashi's hand. 

Kakashi let the boy have the gun and told him about the safety lock before allowing Naruto to do whatever he wants. 

The fastest way for this brat to learn is to let him run free in the wild after all.

Sakura was also excited about her weapon after seeing Kakashi's demonstration and felt like it was good that she let Kakashi do all those things to her. 

He wouldn't treat her badly, right? 

Kakashi saw her expectations and explained to her that although she won't have the same deadly output as Naruto, Sakura could still deal a lot of damage, especially to people who try to get close to her. 

Narutally, he explained about the recoil and how Sakura could use her strong chakra control to stop it and spam the gun as much as she wants in semi-auto mode. 

Of course, the explanation of magazines also ensued…
