Rising from his seat, Natsuo went to take inventory of the medical supplies and noted what was missing before handing it over to the ninjas in charge of replenishing supplies, then retreated to his personal tent.
After several months here, Natsuo asked for permission to have a personal cabin and it was granted.
Having demonstrated his skills in healing and saving many in the camp, his request was not denied and he now lives in a personal tent.
Upon reaching his tent, Natsuo raised his hand and connected through his chakra to the barrier he had placed and opened it.
Closing the barrier after entering, she removed her clothes before taking soap and shampoo and going to a makeshift bathtub in the ground.
Making a hand seal, Natsuo's mouth expelled a large amount of water to fill the bathtub and the seal on his hand changed before he submerged his hands in the water and fire chakra surged.
Within a minute, the water began to steam, and shortly afterwards he submerged himself when the water was hot enough.
Lathering his body and hair with shampoo, Natsuo quickly washed himself in the hot water before forming another hand seal and summoning water into the air, cleaning his body before getting out of the bath.
Drying her body with a towel, she put on underwear and new clothes before lying down on her bed.
Closing his eyes, Natsuo meditated while feeling his chakra.
As his chakra circulated, the amount of chakra displayed grew to that of an elite Jonin.
The others at the camp would be surprised if they knew that Natsuo had the same amount of chakra as an elite Jonin when he was only a few months old.
Of course, Natsuo wasn't worried about anyone finding out because his tent had a barrier that hid what was happening inside.
Neither the sensors nor a Hyuga could see what was happening inside his tent.
While it was known that the Hyuga could see through walls, the Byakugan was not all-powerful, and no clan in the village could live peacefully without fear of their secrets being spied on.
Of course, a Hyuga could tell that his Byakugan couldn't see through a barrier and would realize that something was hidden and would give a warning if the barrier shouldn't be there.
As long as Natsuo suppressed his chakra and didn't enter the battle at full strength, no one in the camp could know his true chakra amount.
Inhale* Exhale*
Breathing at a slow pace, Natsuo smiled and was satisfied with his current amount of chakra.
Since chakra was a mixture of physical energy and spiritual energy, his physical training with more inner gates and the breathing method of the 7 heavens, along with his study and training with shadow clones, caused his chakra to skyrocket.
For someone who only had an average amount of chakra at age 4, his chakra charity equal to that of an elite Jonin proved that his training over all these years has been worthwhile.
And the best part of all?
Natsuo had 10 times the same amount of chakra at his disposal.
How did he do it?
Well, the answer was simple.
He had sealed a shadow clone in his body, copying the concept of a Jinchuriki.
His fuinjutsu studies had reached a bottleneck just before coming to the camp in the land of grass thanks to Mito's help, and for the past few months his shadow clones hadn't stopped practicing fuinjutsu to complete the job.
Since he could now form seals using only his chakra without the need for special ink, his shadow clones didn't require as many materials.
The only problem for his clones to practice without being interrupted or discovered was the lack of a hiding place, which was solved when Natsuo explored the area around the camp for a few moments and returned after creating a shadow clone and sending it to complete the task.
Would the shadow clone run out of energy before completing its task?
Normally yes, but the Senjutsu training has finally yielded its first results.
Although he still couldn't create Senjutsu chakra, he discovered that he could replenish his chakra with the natural energy around him.
This concept worked by taking a small amount of natural energy and circulating it throughout your chakra pathway system.
Although it was slow, it served its purpose.
This concept could also increase his chakra reserves, but it was an extremely slow and tedious process, so he only used it to allow himself or his shadow clone to recover spent chakra.
In this way, his shadow clone could recover the spent chakra and communicate with him when he finished his work.
He simply created a shadow clone, and it disappeared so that he could receive the news.
This underground shelter was several kilometers from the camp, in the land of grass and far from any area that would likely become a battlefield.
With the shelter built, Natsuo sent another shadow clone with new orders while he continued working as a doctor at the camp.
During his time at the camp in the land of grass, Natsuo also did not neglect his training.
He had brought weights in sealing jutsus and trained with them while going for runs around the camp in the mornings.
And upon returning to his tent, he would heal his body before opening 6 of the inner doors and heal his body again before going to the medical tent.
While he worked as a doctor, his two shadow clones followed his instructions and created more shadow clones after recovering lost chakra to fulfill their tasks.
One of them was the SECOND GENERATION JINCHURIKI PROJECT, and they finished it a month ago and notified him.
Since they had already tested it themselves, Natsuo was confident in the results and that same night created a shadow clone before sealing it in his body.
At first the shadow clone only had half of his chakra, but the seal was created with the feature of having access to his chakra pathway system and consuming his chakra to grow.
And in the same way, Natsuo could also access the chakra of the clone sealed in his body to increase his chakra or use it in battle.
And since the seal also allowed the sealed clone inside to have access to the outside, it could draw natural energy to grow or recover lost chakra, even though it was a slow process, since it had nothing else to do.
Another unexpected consequence was that, being connected to his mental space, his clone could help him escape from a Genjutsu, and he remembered that Gyuki could do the same for Killer Bee.
With his growth secured while working as a doctor at the camp, his clones continued with their experiments.
Finally, at this point, their problems of lack of test subjects were resolved.
During a war, it wasn't so strange that some people would disappear, and Natsuo took advantage of that.
Of course, he couldn't target ninjas since they always traveled in groups and he didn't want to attract attention if one of them escaped and alerted others to his presence in the area.
No, Natsuo did not target ninjas for his experiments.
He pointed to bandits.
During a war, bandits are numerous, and Natsuo had a group of clones specialized in traveling to distant areas to capture bandits. Thanks to one of the Jutsus he obtained from the Uchiha patriarch, he was able to bring them back to the refuge without attracting the attention of the two armies fighting in the land of grass.
This jutsu that allowed his clones to travel great distances without attracting attention was the Super Beast Image Imitation Jutsu.
This jutsu works by using chakra-infused ink to draw, and the drawings then jump off
the paper to act according to the user's will.
It is a somewhat weak jutsu for direct combat since almost all of its creations are destroyed with a light blow, but that does not mean it is useless since it is a perfect jutsu for reconnaissance, sealing or traveling great distances on ink birds.
With the bandits brought in by this group of clones, the clones in the shelter could experiment on them to make the process of enhancing bones, muscles, and tendons safe.
In addition, another group of clones took some bandits to do other kinds of experiments using the machines he was able to obtain from the leader of the Uchiha clan.
Satisfied with his current chakra capacity, Natsuo reviewed the information he had received during the day.
