----------
The examination process was very comprehensive. It was not just to check Nawaki's height and weight, but a thorough physical examination of genes, cells, blood, Chakra volume, and even mastery of ninjutsu, so that Ishigami Hara could have a clear understanding.
In this way, Nawaki's data was clear at a glance.
It must be said that Nawaki can indeed be classified as a genius, and his talent is visible to the naked eye.
The physique inherited from Senju Hashirama makes him far superior to ordinary people in recovery ability, which even Tsunade cannot compare with.
Of course, this refers to Tsunade without the use of Strength of a Hundred Seal and Ninja Art: Mitotic Regeneration. In that case, Tsunade, let alone Nawaki, is not comparable to Senju Hashirama. That is the recovery ability that can regenerate even if the body is split in two.
According to Ishigami Hara's estimation, Nawaki's recovery ability is about the same as the effect of his [Training] skill level 3 rapid recovery of around 50%.
With the help of Chakra, a cut wound can be restored to its original state in about ten seconds.
This recovery ability is nothing compared to Ishigami Hara, but it is still first-class in the ninja world.
In addition, Nawaki's Chakra amount is also very good.
Although it has not reached the level of a human-tailed beast, it is at least about nine Kakashi's in the traditional measurement unit of the ninja world, which is nearly catching up with Ishigami Hara's current Chakra amount.
Of course, both Nawaki and Ishigami Hara are still in the development stage and are far from their own limits, and Ishigami Hara's Chakra increase will be faster than Nawaki's.
In terms of ninjutsu, Nawaki has five-attribute Chakra, and his ability to learn ninjutsu in this regard is far superior to that of ordinary people.
He is a genius in the traditional sense.
It is precisely based on this that Ishigami Hara has the confidence to let him master Wood Release in a short time.
After the examination, Ishigami Hara began his own testing.
What he had to do was find the genetic expression of Wood Release in Nawaki. Since the appearance of Wood Release was due to the sacred tree, Wood Release was different from traditional bloodlines. In order to awaken it, one must have the characteristics of the sacred tree.
In this regard, Nawaki was not superior because Ishigami Hara did not find this in him, but it was not difficult for Ishigami Hara because he could start from the Chakra aspect.
Don't forget that Ishigami Hara had gone through the entire process of mastering Wood Release.
In this regard, only Senju Hashirama's resurrection could compare with him in the ninja world.
After all, the Wood Release experience was passed on to Ishigami Hara by Senju Hashirama without reservation.
As for the characteristics of the sacred tree, they were naturally retained by Ishigami Hara's body after being stimulated by Senju Hashirama's Chakra. Therefore, Ishigami Hara only needed to use his own Chakra as a primer for the part that Nawaki was missing.
"Take this potion first."
Ishigami Hara handed the reagent bottle to Nawaki, who swallowed it without hesitation.
...
"Ugh!"
Nawaki's face twisted in discomfort, his expression contorting to the extreme. He was shaking all over and could barely speak.
"What is this? Ugh! The taste... it's like a dish that's been rotten for three days and then had a lot of spices added. It's so disgusting."
Although he said this, Nawaki still reluctantly drank the rest of the potion.
Ishigami Hara smiled but said nothing. This was a potion he had prepared according to Nawaki's physical condition. The effect was simple: to stimulate Nawaki's entire body cells.
As expected, Nawaki's skin began to turn red visibly, and sweat oozed from the surface of his body, accompanied by faint smoke rising. He looked like he had opened the Eight Gates.
"It's so uncomfortable."
Nawaki was trying to endure, and did not doubt Ishigami Hara despite the physical abnormality.
"Hold on, I'm going to use a technique on you now. Remember the feeling of this technique."
Ishigami Hara said, and began to make seals with both hands, not too fast, trying to ensure Nawaki remembered every seal.
"Ninjutsu: Sucking Technique!" (T/N: Sus)
A faint light flashed on his palm as Ishigami Hara placed his hand on Nawaki's chest. The latter immediately felt his Chakra gathering towards Ishigami Hara's palm, draining away bit by bit.
"Huh?"
Nawaki was surprised. Although the Chakra wasn't draining quickly and the amount was small, he could clearly feel the entire process, and even the flow of the technique was within his perception.
"What a wonderful feeling," Nawaki said, closing his eyes to carefully experience it.
What he didn't know was that this sensation wasn't solely due to the technique, but because Ishigami Hara deliberately magnified the feeling through Chakra. The process wasn't complicated—it was just a special application of Yin Release.
Of course, this was simple for Ishigami Hara, but not for others.
After a while, Ishigami Hara disconnected the technique and said, "It's your turn. Perform this technique on me. During the entire process, carefully feel the characteristics of my Chakra."
"Okay!"
Nawaki took a deep breath and, without hesitation, performed the technique just as Ishigami Hara had demonstrated.
The difficulty of the technique was only D-rank, and it was created by Ishigami Hara. The technique's effect was simple: to absorb the opponent's Chakra.
The reason why this technique is low-level is that it only has this basic effect. As for assimilating the absorbed Chakra, that's part of an upgraded version of the technique.
Now, Nawaki could clearly feel Ishigami Hara's Chakra entering his body, and then the cells in his hands began to stir, as if they wanted to devour it.
This wasn't an illusion. Nawaki's cells, stimulated by the special drug, were in a state of hunger. This state required special activity to appease, and Ishigami Hara's Chakra had just the right characteristics.
To put it simply, Nawaki's cells were absorbing the characteristics of the sacred tree that Ishigami Hara's Chakra possessed. Through this Chakra extraction process, Nawaki would now begin to develop the traits necessary for mastering Wood Release.
After a while, Ishigami Hara stepped back, disconnecting the flow of Chakra between them, and asked, "How is it? Do you feel the characteristics of my Chakra?"
Nawaki pondered for a moment and then nodded. "I feel it, such a strong vitality—it's amazing."
He frowned, looking a bit conflicted. "I feel like something's different, but I can't tell what it is."
"Come with me," Ishigami Hara said, leading the way out of the laboratory. Nawaki hurried to follow. Soon, they arrived at a training ground. Ishigami Hara pointed to a small sapling on the side of the field. "Try to use Wood Release to make that sapling grow."
"Can it work?" Nawaki asked, uncertain.
Ishigami Hara just nodded without saying more.
Nawaki's expression grew serious. He took a deep breath and began forming hand seals slowly.
Nawaki had memorized the Wood Release technique well. When all the seals were completed, he suddenly felt something special. His Chakra was being activated by the technique.
It's happening!
With this thought in his mind, Nawaki couldn't help but speak the name of the jutsu.
"Wood Release One Tree Technique!"
Crack, crack, crack!
A small sound was heard as the sapling began to grow at a speed visible to the naked eye. Within a few breaths, it had grown to four or five meters tall.
Nawaki, eyes wide in disbelief, stared at the growing tree, dumbfounded.
Ishigami Hara smiled and said, "Congratulations, you've successfully mastered the power of Wood Release."
