In fact, ninjas don't learn as many ninjutsu as possible. Just like Naruto Uzumaki, the protagonist of the original manga, he has always relied on the combination of [Multiple Shadow Clone Jutsu] and [Rasengan] to fight.
No matter what kind of enemy it is, it will be dealt with by one shot of [Rasengan]; if one can't do it, then two; if two can't do it, make a bigger one; and if that's still not enough, use an advanced version like the [Wind Release: Rasenshuriken].
So when thinking of learning attacking ninjutsu, Chao Yanqian had also thought about whether he, like other Jonin, should cultivate a chakra nature, especially a chakra nature with wind attributes.
After all, in the original manga, the practice of [Rasengan] is introduced the most, including the development of [Wind Release: Rasenshuriken]. The manga also introduces the practice process in detail.
But if you think about it carefully, if you just practice [Rasengan], you might as well continue to use [Guild Force Fist]. The [Rasenshuriken] is a combination of chakra's shape transformation and nature transformation. Unless you use the loophole of [Multiple Shadow Clone Jutsu] to practice, it would take several years.
Therefore, the route of [Rasengan] is not suitable for Chao Yanqian.
And in Earth Release ninjutsu, there are also some powerful techniques, but it is unknown whether Konoha's ninjutsu records contain some strong Earth Release ninjutsu.
The days without missions are actually not boring. After spending two months in Konoha, Chao Yanqian finally made new progress in the configuration of cytotoxicity.
Once this cytotoxicity is injected into the body, it will immediately kill the cells in the human body, and the toxicity is very violent. But when this toxin encounters the First Hokage's cells, it will form a stalemate with the vitality in those cells.
Cytotoxicity cannot kill the First Hokage's cells, but the First Hokage's cells can also halt the erosion of ordinary cells under the suppression of cytotoxicity.
As the research yielded results, Chao Yanqian immediately started the experiment.
As Tsunade's disciple, Chao Yanqian had access to the vast resources of the entire Konoha Hospital. Taking away some experimental equipment from Konoha Hospital under the pretext of research was just a matter of a sentence for Chao Yanqian.
Even during the treatment of the wounded, Chao Yanqian took ten different types of cells from the wounded.
Chao Yanqian separated a small piece from the First Hokage's cells, let the primary cells swallow the ordinary cells, and then injected cytotoxicity into it to observe the effects.
The First Hokage's cells eroded ordinary cells very violently. It would not take long for the primary cells to completely assimilate the ordinary cells. If control is insufficient, a small sapling could even grow out.
However, when cytotoxicity is applied, ordinary cells die immediately, but the First Hokage's cells can stubbornly resist the toxin, and the vitality within them gradually offsets the cytotoxicity.
When the cytotoxicity loses its effect, the primary cells continue to erode ordinary cells and revive the necrotic ones.
After ten consecutive experiments, Chao Yanqian discovered that even if a vaccine that can be immune to cytotoxicity is developed, to perfectly integrate the First Hokage's cells, one must inject cytotoxicity periodically until the primary cells are fully fused with the host's body.
The method of fusing the First Hokage's cells developed by Orochimaru required the experimental subjects to have a strong compatibility with them. Therefore, among so many experimental subjects, only one person, Yamato, survived.
However, Shimura Danzo's method of fusing the First Hokage's cells was very crude. Once the suppression by the Sharingan was lost, the primary cells would immediately spiral out of control.
Perhaps there was collusion between Orochimaru and Shimura Danzo, but it is undeniable that the fusion of the First Hokage's cells is dangerous.
The cytotoxicity developed by Chao Yanqian is actually similar to the suppression method of the Sharingan. It suppresses the primary cells and slows down the erosion of ordinary cells by the primary cells.
The most important thing for Chao Yanqian to fuse the primary cells is to obtain the research results of Orochimaru and use his method for fusion.
Although Chao Yanqian is confident that he has mastered part of Orochimaru's research, it is unknown whether Orochimaru concealed certain key points.
After staying in Konoha for two months, Chao Yanqian could not help but once again raise the idea of going to the front line to find Orochimaru.
Naruto Office.
"It's you, Chao Yanqian! Why are you here?" The Third Hokage greeted enthusiastically as soon as he saw Chao Yanqian.
In two months, the storm of the Three Tails incident had long since passed, and the benefits of this incident had finally been revealed. Although Kirigakure, whose village was devastated, couldn't wait to kill all Konoha ninjas, they were eager to rebuild and could not afford to continue foreign wars.
Although Kirigakure did not officially announce defeat, they also reduced harassment on the border of the Land of Fire, and Konoha's pressure was greatly reduced. In addition to necessary precautions, Konoha had shifted most of its forces to the confrontation with Kumogakure.
"Hokage-sama, now that the Three Tails storm has passed, I have applied to return to the battlefield!" Chao Yanqian said solemnly.
"Um... that's it." The Third Hokage thought for a while, then frowned: "There are some things that it's fine to tell you. Now we have formed an alliance with Iwagakure. The Third Tsuchikage, Onoki, has also agreed to send troops against Kumogakure, but he asked Konoha to bear the brunt of Kumogakure's main force."
"Onoki wants to gain benefits without suffering losses. It's truly a clever calculation," Chao Yanqian said.
"Furthermore, although Kirigakure was damaged this time, it didn't hurt their foundation. They still have the strength to fight, just choosing to hibernate temporarily," the Third Hokage continued.
"What does Hokage-sama mean?" Chao Yanqian asked in confusion.
Although the Third Hokage analyzed the situation of the Ninja World, he hadn't specified what to do.
"I hope you can stay in the village for the time being. When Iwagakure takes action, you will show up near the Land of Water..." said the Third Hokage.
Damn it—he really is an old fox.
Once Chao Yanqian appeared, the Mist ninja would definitely pursue and kill Chao Yanqian with all their might. At that time, Konoha could withdraw most of its troops from the confrontation with Kumogakure under the pretext of resisting Kirigakure.
But by then, Iwagakure would have already engaged Kumogakure, and it would be too late for them to retreat.
However, Konoha could use the excuse of guarding against Kirigakure to withdraw part of its troops from the Kumogakure front. While preserving its strength, it could sit and watch Iwagakure and Kumogakure fight.
"I see! I will continue to stay in the village, waiting for Hokage-sama's orders," Chao Yanqian said solemnly.
After walking out of the Hokage's office, Chao Yanqian was a little depressed but could only accept all of this.
As for Orochimaru's research results, it would have to be taken one step at a time. Perhaps he could also cooperate with Shimura Danzo to obtain Orochimaru's research.
It would be best to take advantage of an opportunity to sneak into Orochimaru's laboratory while he was not in Konoha...
