In the records of Sunagakure's poison research, there is a poison that can cause cell necrosis. If this poison's toxicity can be increased to a critical point, it may have the effect of suppressing the First Hokage's cells.
This is one of the ideas of Chao Yanqian. The use of poison to suppress Hashirama's cells was an idea proposed by Chao Yanqian long ago.
Now that he has the First Hokage's cells in his hands, Chao Yanqian can use this to formulate a poison whose toxicity can suppress Hashirama's cells without causing their necrosis.
However, if this poison is injected into the human body, while suppressing the First Hokage's cells, it will definitely kill the ordinary cells in the body. Therefore, Chao Yanqian eagerly hopes he can find a way to neutralize this toxicity.
Early the next morning, Chao Yanqian came to the archives of Konoha Hospital and retrieved the antidote formula that Tsunade had prepared.
However, the formula of the antidote was disappointing to Chao Yanqian because the antidote developed by Tsunade could only resolve the toxicity but could not revive necrotic cells.
If the poison and the antidote are injected into the body at the same time, the only effect achieved is that the two medicines cancel each other out that is, the antidote resolves the toxicity of the poison.
But if the survival of ordinary cells cannot be guaranteed, even if this poison can suppress the First Hokage's cells, it will be useless. If the person dies from poisoning, what use are the First Hokage's cells?
After thinking about it, he finally decided to first study the pharmacology of the antidote and see if he could formulate a vaccine to prevent the poison's effects based on the antidote.
If there is a drug that can grant immunity to this poison after being taken, it would be possible to fuse the First Hokage's cells and then use the poison to suppress them, thereby achieving a slow fusion effect.
To complete this idea, the first step is to formulate a poison that can suppress the First Hokage's cells without killing them, which Chao Yanqian calls "cytotoxicity."
The second step is to configure a vaccine that can grant immunity to the cytotoxic poison and inject it into the body.
The third step is to implant the First Hokage's cells into the body following the method developed by Orochimaru for primary cell fusion.
In fact, most of Orochimaru's sixty experimental subjects began to gradually fuse with the First Hokage's cells. However, the erosion capability of Hashirama's cells was too strong, and the subjects were too young, so only one out of sixty succeeded ,Yamato.
Nonetheless, it is undeniable that Orochimaru's experiment was successful.
Therefore, the method of fusing the First Hokage's cells is to use Orochimaru's technique, supplemented by medicine, to allow the fusion degree to reach Yamato's level.
As for the fourth step, it is to suppress the First Hokage's cells with cytotoxicity, preventing them from quickly overwhelming the host's original cells, thus achieving a slow and stable fusion.
If this plan succeeds, Chao Yanqian estimates he should be able to reach Yamato's level: perfectly integrating Hashirama's cells without attaining the overwhelming power of the First Hokage's Wood Release.
There is always a part of the human body's cells that continuously divide and differentiate. Normal levels of cell necrosis can be eliminated by improving blood supply and increasing cell metabolism.
Generally, almost all tissues can self-repair when damaged, except for nerve tissue.
In particular, the vitality contained in Hashirama's cells is extremely powerful even if separated from the body for decades, they can remain active. To suppress such cells, extremely strong toxicity is necessary.
After returning home, Chao Yanqian began his own experiments.
First, he increased the concentration of cytotoxicity, then tried adding some new poisons to see if the toxicity could be raised enough to suppress the First Hokage's cells.
Any experiment is tedious and lengthy. Chao Yanqian delayed his recovery time as much as possible, but after a month, his injuries were still recovering steadily. He could now carry out daily training and even participate in missions without any impact.
After recovering, Chao Yanqian naturally had no reason to remain idle. As team leader, Sarutobi Asuma and Yūhi Kurenai performed two missions to hunt down rogue ninja. Chao Yanqian was excluded from these missions, and all his time was spent studying cytotoxicity.
During the war, there are deserters from every village, but Chao Yanqian preferred to call them cowards.
Compared to dangerous missions, hunting deserters who feared death was obviously more time-efficient.
Konoha had been at war for too long, and most of its ninja were showing signs of war-weariness. Therefore, Chao Yanqian guessed that the village leaders might soon seek to end the war with Kumogakure and pull Konoha out of the quagmire.
Just a few days ago, Chao Yanqian had a meeting with Shimura Danzō. Danzō subtly implied to him that the Third Hokage was considering an alliance with sunagakure against Kumogakure.
To persuade Ōnoki to agree to the alliance, Konoha paid a high price.
Of course, Danzō's real goal was to sow distrust between Chao Yanqian and the Third Hokage.
After all, Konoha suffered heavy losses in the war against sunagakure, and Chao Yanqian also participated in that battle. The Third Hokage's actions could be seen as betraying those who shed blood for Konoha.
However, from a broader perspective, the Third Hokage was not wrong: ending the war sooner to minimize future losses was necessary.
After all, the dead cannot be resurrected, but the living must continue to survive.
Despite Danzō's manipulations, Chao Yanqian had no intention of getting involved in the power struggles between Shimura Danzō and the Third Hokage.
As time passed, the decisive battle between Konoha and Kumogakure drew closer. Before heading to the frontlines, Chao Yanqian needed to finalize his cytotoxic formulation and earn Orochimaru's trust.
Originally, Chao Yanqian planned to distance himself from Orochimaru to avoid being implicated when Orochimaru defected. But if Shimura Danzō promised him protection, Chao Yanqian was willing to cooperate temporarily with Orochimaru.
Although this approach was risky, after so many years, Chao Yanqian had grown accustomed to taking risks.
Sometimes it's worth taking a risk for the sake of potential gain.
Two more months passed, and the official order for Chao Yanqian to deploy to the frontlines was finally issued.
It seemed that Uchiha Obito had awakened from his deep slumber Kirigakure suddenly declared a truce with Kumogakure and turned their blades against Konoha.
This decision by Kirigakure puzzled everyone; no one understood what the Fourth Mizukage was thinking. However, there is no true justice in the ninja world's wars. Everything is for profit. Perhaps Kumogakure offered Kirigakure great benefits!
