Naruto: Starting as a Root trainee in a White Room Program( Rewriting)

"Your plan was really good but did you forget that other people with stealthy skills exist?"

Now, this abducted Nara might have been brainwashed with all his memories removed, but the memories of shadow possession jutsu weren't removed for obvious reasons.

"Well, anyway, I guess, that is it for you, I would have loved to leave you alive, but I fear that you might take revenge and come after me, I don't really want to know how I will fare against you, so let's end this meeting."

Just as he was going to put the Kunai, he got bashed in by somebody behind him.

Then, he looked behind, he could see the same guy waving his hand behind him, "Indeed, I know that I am not the guy in this exam with the best stealth skills" He heard which was the last thing after which everything blacked out.

The real No.13 completed the action of putting his plaques in his seal while giving a thumbs to his lookalike which merged seamlessly with the earth. Earth Clone Jutsu was cheaper than Shadow Clone Jutsu chakra-wise.

No.13 left the scene and in a random location entered the earth to stay there to recover his chakra as he was down by less than half, so after creating another earth clone, he decided to take a nap to recover his chakra as it was the second best way to recover chakra after active meditation but the latter causes mental fatigue which is only optimal during training but not on field as delay of just one second on battlefield can cause one's death.

Also, the problem of air was easily solved by storing air in the storage seals previously.

He woke up at night, and after eating something, he left the underground and reached the surface. Now, some people would rather rest at night, but for him, the night is for the hunt and seeing the sound of explosions and jutsus going out, he could see that others agreed with him, so he made a beeline towards the nearest fight he speculated was happening.

"Wind Style: Cresent Moon Slash"

"Water Style: Tidal Waves of Fury"

A Clash of Jutsus could be seen by Green and blue-haired individuals, A normal ninja might need to do a double take as these people were clearly Chunin level and looked around 10 years old.

No.13 watched as these idiots used their chakra like there was no tomorrow, he sometimes wondered if Idiocracy was hereditary or not, communicable or not.

He remembered a saying he heard in his previous life, "Fools don't have horns on their heads, they are people among us."

Well, he doesn't mind taking the plaques from them, they are gonna lose it anyway, so with that in mind, he retrieved his prize but it seems that somebody else had similar plans as they shot a kunai with explosive tags at him.

However, he plays with those tags, how can he get hurt by such an immature way of catching others off guard, they didn't even have the decency to use genjutsu.

He quickly body flickered while putting his prize away. After some misdirections and whatnot just to lose the trail behind him, he finally found out who was following him, it was an earth user just like him.

Just as he was in his hiding spot, the other Earth user who was not in the ground currently said "I know you are there, Are you coming out or Do you want me to drag your sorry ass out" He said while brandishing a brand new kunai.

However, unlike what the other person demanded, No.13 didn't give away his spot and waited for the other party to make their first move.

"Well, fine, let's do it this way," He said while tensing his muscles of the hand, which made No.13 alert, He threw the Kunai which wheezed the air and went out of view very quickly due to night time.

That guy missed speculatively, even No.13 could feel the second-hand embarrassment from that incident, yet this guy didn't even blink.

This level of bluff was really dumb or genius if it worked.

This guy crouched down put one hand on the ground and closed his eyes, seemingly dropping his guard but No.13 saw through what he was trying to do.

No, he wasn't trying to make him lure him into attacking him... or maybe he was but that wasn't the primary intention.

He was using 'B rank: Earth Sensing Jutsu' to find out his location, but unlucky for him, No.13 was on a branch not on the ground.

At least that was what No.13 thought he was trying to do as he did this action without performing any hand seals, so he had no way to confirm it.

That guy, looked around a bit and then went into the earth seemingly escaping from the scene.

However, how can he leave after attacking No.13? He has to face the consequences of his actions!

On that note, No.13 jumped off the branch and just as he was landing on the ground, he used a chakra burst to reduce all that momentum, making him land softly on the ground such that vibrations were very minimal just as his bare feet touched the ground.

To use the sensing jutsu that the guy used before, one needs to have contact with the ground where they can use their chakra properly and No.13 seems to have similar equipment on his feet( kind of like bracers), that he has on his hands on which Seals are imprinted, which could be used to store away his footwear instantaneously.

When he landed, he noticed that there was no vibration in the ground within 100 meters, so he assumed that the guy was still camping, 'Talk about paranoid'

'Should I kill him? Things would be so much easier, I could just put my hand on the ground and an earth spear would kill him...' Just as he had that thought, he squished that thought away, Killing children is not something he wants to do this early, plus all of them seems to have potential, so it would feel like a waste if they died by his hands.

Now, some may argue that most of the kids here are aiming to kill him, but that doesn't necessarily mean that he had to reciprocate that feeling, In the beginning of the match, He actually was not going to set off the explosion tags aimed at the ice guy but seeing that he can do a very destructive move, he wanted to test the guy, so he did that. 

Even if that guy would have failed to put a defensive jutsu, at worst he might have suffered Major Burns which could have been cured by the No.13 himself, should he feel like that?

If things are under his control, then he won't mind stopping an unnecessary kill as he really is not a kill maniac and appreciates life. He knows that killing one person is the same as ending all their dreams and aspirations, ending their journey since day one which in itself is sad and he would rather not see such fate happen to him or anybody, but also, if killing means his survival, then he would do it as he won't let anybody snuff out his dreams or end his journey.

Plus, we are dealing with kids who have learned things from adults, these are the kids who didn't make faces during their first kill or something as this is just their norm of normalcy, so it's not like they are going out of their way to do something, obviously, things will change if his opponent is an adult.

Just as he was pondering what to do next, No.13 jumped from the ground and did his version of substitution mid-air to land on a branch.
