Naruto: The man is in the Senju, but the Sharingan

A few days later, Tobirama Senju and Hashirama Senju returned from their mission, and Kagamigawa Senju resumed his previous training.

Because in the previous battle with Uchiha, Senju Kagawa was easily deceived by the one-magatama Sharingan illusion, Senju Tobirama specially made a plan to deal with the illusion for Senju Kagawa.

The most important part of this plan is chakra.

Fortunately, after using "Please Don't Die", Senju Kagamikawa found that he could actually absorb chakra. Although the amount of chakra that could be absorbed was very small, at least Senju Kagamikawa now had the possibility of using ninjutsu.

As for why Senju Kagamikawa was unable to use chakra before, Senju Tobirama gave a reasonable explanation.

As a future "scientist" in reserve, Tobirama Senju's talent in research has already begun to take shape.

When Kagamikawa Senju was unable to absorb chakra, Tobirama Senju took some of Kagamikawa Senju's cells for experiments.

Now, Tobirama Senju has taken some of Kagamikawa's cells.

By comparing the two cells, Senju Tobirama finally discovered the problem -

Previously, the metabolism rate of Senju Kagamikawa's cells was too fast, and the cells were usually metabolized before they absorbed enough chakra. This cycle continued, and those cells containing chakra were either metabolized or blocked by cells that did not produce chakra.

Therefore, the chakra pathway of the Senju Kagami River is completely blocked.

The reason why Senju Kagamikawa is able to use chakra now is naturally because his cell metabolism rate has returned to normal.

When talking about research, Senju Tobirama's red eyes became sparkling and the corners of his mouth unconsciously curled up into a smile. It can be seen that Senju Tobirama likes scientific research very much.

"However, I have not yet figured out the reason for the change in your cell metabolic rate." Senju Tobirama sighed. He has been troubled by this matter for several days.

When Senju Jingchuan heard this, he couldn't help but think about the changes in himself before and after the injury.

Before being injured, Senju Kagawa's body would usually perform healing magic on its own, but after using "Please Don't Die", Senju Kagawa did not use healing magic on the existing wounds, and naturally stopped using healing magic on the entire body.

Senju Kagamikawa told Senju Tobirama this conjecture.

Both Tobirama Senju and Hashirama Senju knew that he had not been able to use chakra before, so the "medical ninjutsu" that Senju Kagawa used in the past could only be Senju Kagawa's unique talent - a skill that does not require chakra support.

However, Hashirama Senju and Tobirama Senju did not make the matter public. They believed in their younger brother and did not want their words to become a sharp blade that hurt him.

So, Senju Tobirama pondered for a moment and quickly accepted this explanation:

"In that case, it is very likely related to your healing skills."

"Your healing technique is different from the general palm magic. Most palm magic focuses on stopping bleeding and transferring lost vitality to the wound through chakra. Only a small part of it focuses on the same thing as your healing technique - stimulating cell division and regeneration."

"However, medical ninjas generally don't perform medical ninjutsu in their bodies all day long. Therefore, even those ninjas who focus on stimulating cell regeneration will not have their own cells metabolize too quickly..."

As soon as Senju Kagamikawa heard Tobirama's explanation, he understood that it was his own fault that he couldn't use chakra...

Senju Tobirama thought for a moment, then his face became serious. He asked Senju Kagawa:

"Kamigawa, do you know that too fast cell metabolism is not a good thing?"

Senju Kagawa nodded.

Then Senju Tobirama continued:

"Rapid cell metabolism can provide more physical energy, but the number of cell metabolisms in each person's body is limited, and each cell metabolism will consume your original vitality."

Senju Jingchuan was shocked when he heard this. It turned out that he had been using the healing technique purely for the sake of seeking death.

When Senju Tobirama saw Senju Kagawa's face turn pale, he knew that he had heard it. He slowed down his tone and continued:

"Although the vitality of the Senju clan is stronger than that of other ninja clans, but... too fast cell metabolism is not a long-term solution. Do you understand?"

Senju Jingchuan nodded hurriedly. He now realized how suicidal he had been in the past.

In this Warring States Period when the average life expectancy is 30 years, Senju Kagamikawa actually dares to create his own vitality in this way. Doesn't he think he has lived too long?

If Senju Jingchuan continued to destroy his vitality like this, he might not die on the battlefield, but die from his own healing skills.

Senshou Jingchuan's face is still pale, and he feels a little scared when he thinks that he almost killed himself.

It has to be Brother Tobirama. If it weren’t for him, I probably wouldn’t know the cause of death until I die.

So if Senju Jingchuan stops using healing magic, will the life span of the patch value conversion increase?

Senju Kagawa decided to give it a try.

Sure enough, just as Senju Tobirama said, after he stopped using healing techniques, his life conversion value did increase.

[As expected, everything is excessive or inadequate.] Senshou Jingchuan couldn't help but sigh.

After figuring out the chakra of Senju Kagawa, Senju Tobirama began to develop a chakra training plan for Senju Kagawa.

The first thing is to test the chakra properties of Senju Kagawa.

Senju Tobirama handed Senju Kagamikawa a piece of gray paper.

Senju Jingchuan had never seen such paper before. He asked in confusion:

"Brother Tobirama, what is this?"

Senju Tobirama explained:

"This is a chakra test paper. You input chakra into the paper and it will detect your chakra attributes."

As Senju Tobirama spoke, he took out another chakra test paper and injected chakra into it. Then, the chakra test paper became wet and water dripped down.

Senju Kagawa carefully transferred the chakra to his fingertips and then input it into the paper.

The next second, a corner of the paper was wet, but it was not as wet as Senju Tobirama's.

Senju Kagamikawa twisted the wet corner of the paper with his fingertips and asked in confusion:

"Why is only one corner of this chakra test paper wet... It's completely different from Tobirama-san's..."

Senju Tobirama smiled and stroked Kagamikawa's white-haired head, explaining:

"That's because you have too little chakra. If you had the same amount of chakra as I do, the chakra test paper would be soaked."

"But... you have the same water attribute as me... that makes it easier. From now on, leave your chakra training to me."

Senju Tobirama thought for a moment and said, "So, I still need to train your ability to break illusions first..."

When Senju Kagamikawa saw Senju Tobirama thinking seriously, he knew that his future chakra training would not be easy.

Qianshou Jingchuan wanted to cry but had no tears.
