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

{Killer Bee: "I am peeking at you. See you're not quite through, but in all your crew, your brain cells are few." - Killer Bee vs Sasuke Saga}

In the very early morning, various groups of children could be seen scattered around the entry of a different forest, this one was much bigger than the previous one, with Kids ranging from 7 years to 11-year-olds could be seen standing with ninja equipment.

A Familiar Trio containing No.13, S-chan and Delta could be seen standing with an instructor. Their Goal was to win this tournament and for that, they were prepared. They entered the forest just as the instructor signalled them to. 

Plaques varying from No.1 to 96 were distributed with secrecy so that nobody would blatantly gain meta knowledge for that.

This team was given No.68 and their goal was to hunt Down No.95 plaque.

"Remember the plan and we will win this" No.13 reminded and both nodded.

Their first target was acquiring the 95th Plaque. They were given information about plaques in a closed room, but He had asked S-chan before to camp in that room to gain information about the target formerly and she had done that job wonderfully.

Their Target team contains 3 10-year-olds, gaining information about anything else was hard as information about plaques was given in the dawn only.

They were heading towards the possible route those guys would take depending on the entry point they knew of these guys.

After stealthily going for an hour, they found those guys.

At least the corpses of those guys.

"It seems someone killed them by Mystic Palm, a combat Medic probably" No.13 shared his views.

"So, his chakra enhancement should also be taken into account when fighting such a guy or girl? also, was he alone or did he have a team but still fought alone?" Delta asked

"Better safe be sorry, but for now, let's leave the scene, we don't know if somebody will come here from the sounds of battle earlier," No.13 said but just as he completed that statement a barrier seemed to enclose the whole area.

"5-Point Barrier of Entrapment"

10 individuals enter the barrier and start throwing Kunai with Explosion tags, the outside view is replaced by darkness, it seems it puts a visual Genjutsu or blocks light itself from entering the enclosed area.

"Formation E" No.13 reacted quickly and got in the middle of Delta and S-chan, the latter both using Gale Jutsu to Repel the Explosives.

"It's a cubic structure, we can't escape underground." No.13 Informed

"You guys buy me some time," S-chan asked and both compiled.

The projectiles were soon replaced with Jutsus of all 5 elemental natures, Things like Fire Ball, Wind Slashes, Mud Projectiles, Lightning arrows and Water Bullets were indiscriminately thrown around.

No.13 created a small but Multi-layered Mud Wall for all three to take Cover. It was annoying that They were bombarded from all sides.

"S-chan, How much longer?" No.13 asked.

"I can't sneak up on them if we are bombarded from all sides."

"I won't last too long with my chakra reserves, I am gonna give you an opening, don't waste it," No.13 said while Taking out nearly a dozen Senbons.

"Throw these with Wind-coated chakra on one side only when I signal," He said while giving it to S-chan who just did that. Meanwhile, No.13 weaved some hand signs.

"Now"

Dozens of Wind Coated Senbon multiplied to Nearly 100, all with Wind Chakra Coated. This is one of the reasons Shrinken Shadow Clone Jutsu is considered A rank.

The Earth elemental tried to act quickly by putting up a mud wall, but halfway through the wall got penetrated quite easily. The interesting thing was that despite S-chan aiming for the vital parts, the senbons including both real and shadow clones of it didn't actually pierce any of the vital parts of their opponents, but it sure severed some of the arms and legs of some or pierced through various non-vital body parts such that they won't possess a threat.

Survival is difficult but not impossible if they apply immediate medical attention. Another surprising or unsurprising thing was that nobody who got their Appendages chopped or pierced screamed despite the pain that could be seen on their faces.

These kids are built differently, this was clear, however, just having one side free from assault eased the tension on No.13 who was holding the fort with his mud wall.

S-chan delivered what she promised, in less than half a minute, all assaulters had a kunai-sized hole in their head.

"Be Careful, I bet people who are outside or are maintaining the barrier can see what we are doing, We don't know how many are outside, so don't drop your guards" Just as He said that there were holes in the barrier and from those holes, Kunai was being thrown.

With explosive tags, of course as the topping.

'B rank 'Lightning style: Electromagnetic tussle'

This was the same jutsu one of the opponents in the previous round used to deter No.13's explosive streak. Now, No.13 didn't have a sharingan, and neither did the opponent use any hand signs for it unlike No.13 who used one sign, but it didn't stop No.13 from creating his own self-version of this in the last round itself.

His Earth Release Elemental Training of Crumbling the Leaf might not be completed unlike other people he had watched in Round One, but his theoretical knowledge and the fact that he knew all the D ranks of all elemental Nature was a fact that he only knew.

If he cannot copy, then he will create!

On that note, all the projectiles burst at the barrier itself, it also didn't help that at the same time, both of his teammates used the most destructive jutsu in terms of penetration on one part of the barrier together.

In that way, They used Body Flicker and escaped the Barrier. S-chan didn't find any plaques in those bodies that entered the barrier.

"So, Retreat or advance?" Ice-Guy asked

"S-chan?" No.13 looked at her.

"I can kill them" She confidently said, even a sensor only has a 40 per cent chance to survive if she wants to kill him and also this is the case if she is not super serious.

"Well, will distract them," He said Unfurling a scroll that sent hundreds of Kunai towards the enemy via air. It was honestly a beautiful sight to see... the explosion which followed. 

This attack was done from outside the encirclement of theirs, these guys had around 15 members still alive. Well, that status didn't last too long. 

Even without S-chan's help, half of them died by just getting hit by either the kunai or explosives. 

Either they were chakra drained or didn't really have learned any defensive jutsu. No.13 would bet on the former.

"I found a plaque, it seems they weren't the ones who killed our targets" S-chan informed the other two.

"Let's recover our projectiles and anything we can recover from these guys and quickly change our locations" No.13 said while internally praising why chakra threads would have been so convenient even in his previous life.

He tossed some explosive tags to S-chan, "Use these and throw some projectiles with your wind jutsu, don't throw it too high such that people from far away would notice, throw it in north to north-east, and people heading here will change their direction hopefully."

"Senpai, you are a genius, I haven't even seen such strategy in standard strategy books" 

"It seems that you haven't read the book then, have you?" 

"Te-he" S-chan winked in a non-apologetic manner

After everyone collected the projectiles, they headed towards the east with Shunshin or jutsu as that was the only cardinal direction that sounded peaceful unlike the other three.

After reaching half a kilometre they took a break, S-chan took a step forward and something unexpected happened.

A Fuinjutsu Seal could be seen on the ground which paralyzed the trio.

"See, it was easy" A feminine child-like voice could be heard.

"Well, it was" A black-haired child replied.

On a tree, a black and white duo could be seen weaving hand-signs, one noticeable thing was that they both seemed to have similar appearances despite the contrasting gender.

Both completed their jutsu at the same time. From the girl's mouth, a fireball was shot and from the boy's wind was shot.

Now the surprising thing was that both jutsus seamlessly combined to form a big fireball whose hotness could be felt from even a long distance.

It was a Combination Jutsu.

Combination Jutsu as the name implies is the combination of two complimentary jutsus and it requires skill and timing to perform it. Jutsus could either combine at the moment of impact or mid-process like what was happening now.

"S-chan"

The chakra that was building inside her from the time they got trapped was now released at the ground destroying their seal with wind. This helped them use Shunshin to disperse in three different directions.

The impact of that combination jutsu could be seen various meters away even.

A person's bones might not even be left if they got hit by such jutsu. Despite Two C ranks firing, their destructive power could rival Low A rank jutsus.

The area that hit was vaporized completely.

"Tch, it seems they do have some luck," The boy said

"Well, let's divide and conquer," The girl said and shot herself at No.13.

The boy followed the girl soon after.

The girl started her assault by harassing No.13 with Senbons Coated with some stuff that only she knows. No.13 dodged by using his substitution consecutively. Seeing that her approach was not working, she closed the distance, hoping to burn him alive by using jutsu at close range.

The boy on the other hand was standing on the branch and had his eyes closed. Suddenly, he threw a shrunken a random direction which actually was blocked by a kunai by S-chan who was not at that location.

"A Sensor eh? Well, more fun for me to break you"

"Hmm, you are using a projection genjutsu using wind to hide your traces... You really have a good affinity with the wind to create such a jutsu"

"Bingo, you are correct! Unfortunately for you, you aren't the first one to figure it out, so your reward will be your death" S-chan disappeared from view. 

The wind-boy who also was a sensor couldn't find her out if she was outside his range.

Back to the battle with the white-haired girl and No.13, it seems that No.13 didn't even sweat while dodging the former's fireballs, however, the White-haired girl seems to be slightly panting already.

Chakra is converted from the Stamina of a person!

There is a reason why one cannot recover it instantaneously after it has depleted. There are some exceptions to this rule, but back to the battle.

"Can't you stop for a second, let me burn you"

"Well, I don't like fire "

"I will make it quick, don't worry"

"That somehow doesn't reassure me"

"Tch, such a wimp"

"Such a sore loser, can't even hit a wimp at such close range, may as well give up being a ninja"

"I am considering," She said while now charging with a kunai in hand at the target who seemed to not get anywhere close to her.

Meanwhile, Ice-guy was not dilly-dallying.

No, He didn't run away from that psychotic murderous girl who calls herself a teammate, no matter how much he wanted to.

He was currently dodging for his life from a blade-wielding girl. Now, one may wonder, why he let her close the distance between them as he was a ranged fighter which is a thing that he definitely shouldn't do, no matter how confident or skilled he is.

Well, The answer to that question would be that he never let the girl close the distance. This girl was sending Flying slashes left and right. His ice attacks were cut like butter by her sword coated with normal chakra which oddly was glowing.

He had to use his ice attacks to propel himself away from his previous location just to dodge her attacks. She seems to Easily guess where he would be, making it more dangerous for him to use that jutsu.

He was not leading her towards his other teammate while dodging in hopes of switching their opponents. 

Back to the only male teammate of the opponent team, he had successfully employed his Fuinjutsu which enclosed him and now visible S-chan.

"Fuin: Equalizer"

"My chakra... It's too wild for me to control it and it is constantly getting sucked by this barrier."

"Don't-bother, this is an A rank Fuinjutsu I learned, Both of us now couldn't use chakra, it is now used to supply to this barrier, now let me show you the difference between our physical prowess" That guy brandished a Kunai and swung wildly at her. S-chan just parried it away with her kunai.

"How annoying"

Ice-guy or Delta was successful in reaching his other male teammate. "Hey, you seem to be having it easy, Switch with me" 

"Weren't you boasting about how you were going to dominate opposing teams alone, Now you can't even handle a chick?" No.13 landed a swift kick on the white-haired girl while in the next second substituting to dodge the fireball coming at him.

"I take it back, I don't wanna die" Ice-guy was on the verge of crying 'I just wanted to have some fun, when did this become a deathmatch'
