Yes, as early as after Li Chun obtained the body tissue of Sasuke Uchiha, Li Chun's body had already been teleported back to his home, and what was left was just a shadow clone.

After dealing with the vignette about Sasuke Uchiha, Li Chun started the clinical trial on animals with Shizun after a day of rest.

After all, the composition of the original enterovirus has been analyzed, and the next step is naturally to need non-stop clinical trials to obtain data.

In the former underground laboratory of the roots, Li Chun and Shizun stood in front of an operating table.

This is where Li Chun and Tsunade Ji specially applied, after all, the equipment that Tuanzang has equipped the laboratory with is very complete.

In addition, the test on the original intestinal virus was not suitable for Konoha Hospital, so Li Chun made the idea here.

After Tsunade-hime agreed, Li Chun and Shizune occupied the laboratory in the root research area.

Anyway, it is impossible for the dark department to move the base here, after all, this place has been thoroughly explored by Li Chun.

So instead of putting it away, it is better to use it and let Silent and Li Chun use it.

"The first in vivo trial began, and the injection was a fusion gene solution of the original enterovirus and the blood of the writing wheel." After speaking, Li Chun injected the produced gene liquid into the anesthetized mice.

As the gene fluid was pushed into the body of the mouse by Li Chun through the syringe, the mouse began to quickly thin down in the eyes of Li Chun and Shizun.

"The degree of integration is 20%... 27%... Subject died... Survival time is 56 seconds, now dissection begins. Li Chun stared at the mouse and said.

The mute on the side is responsible for recording the data, after all, the identification skills she obtained through the panel cannot see the exact data yet, and there is only one mouse in the message box that has been eroded and infected by the genetic fluid mixed with the original intestinal virus, which is a simple identification result.

Only after her appraisal has become an appraisal that Li Chun does not have to dictate the process.

After the silent recording was completed, the guinea pig, which was almost equivalent to a dried corpse, was dissected by Li Chun.

"The cause of death was organ failure... It is suspected that the vitality was drained during the fusion process... There was no abnormality in the brain, and the degree of erosion was 27%... The first trial ended. After carefully dissecting the body of the mouse, Li Chun put down the dried corpse in his hand and sealed it into a scroll.

When it comes to the original intestinal virus, all test subjects must be destroyed, otherwise the Hokage World is estimated to have a cataclysm.

Of course, there are supernatural powers, and the end may not come.

However, there is a possibility that ninja beasts will overtake humans, so each test subject must be carefully disposed of and retrieved.

"Chun-kun, what do you think is the reason for the failure of this experiment?" Mute asked as he recorded.

"It's probably because it takes a lot of energy to transform ordinary genes into extraordinary genes." After thinking about the situation of people infected by the original intestinal virus in the dark world, Li Chun came up with this conjecture.

After all, in the dark world, infected people don't have this kind of physical failure.

That is to say, after ordinary mice are injected with transcendent genes, along with the erosion and proliferation of transcendent genes, the vitality of the mice is consumed.

"In other words, do you need to prepare a large amount of nutrient solution in advance for the next test?" couldn't help but ask.

"It may not be too late, you have also seen that ordinary mice are eroded too quickly in the face of extraordinary genes, and I am afraid that I will not be able to complete the experiment with the nutrient solution alone." Li Chun couldn't help but touch his chin and said.

"Is that to use the technique to inject immortal power?" Mute continued to ask.

"Let's test it with a separate nutrient solution first, and don't be in a hurry to inject fairy power. In fact, it is best to find a ninja beast with chakra to experiment, so that the data obtained is more accurate. Li Chun shook his head and said.

"Chun-kun, Lord Slug may not be willing to cooperate with us." Mute shook his head at Li Chun.

"I know, that's why I didn't let you channel the clone of the slug immortals." Of course, Li Chun knew that the slugs in the Wet Bone Forest were not easy to get along with.

Don't look at the soft-spoken, but if you want to do something with it, people may not be willing.

After all, the doppelganger who has done the experiment must not be able to reintegrate into the body, that is to say, each experiment means that the slug will lose part of its body, and it is good to say once, there are many times, do you really think that the immortals are vegetarians?

The ninja beast that Li Chun really likes is actually the psychic beast ape of the Ape Fei family, after all, the genes of apes are the closest to humans.

And he can also speak, and say everything he feels physically.

Of course, even if Li Chun didn't make a suggestion to suppress the Ape Fei clan, it would be impossible for them to hand over the psychic contract.

Not to mention handing it over, after one or two apes disappear, people can also not respond to psychic calls.

Therefore, any ninja beast with a little wisdom can only be thought about by Li Chun.

Of course, Li Chun doesn't necessarily need such a high-profile test subject, in fact, after the first experiment, Li Chun will be able to know what problems he will face.

After having the exact data, Li Chun will be able to take countermeasures in advance according to the data during human trials, so as to better reduce the probability of death of the experimental subjects.

After completing the animal experiments, Li Chun can start the live experiments of ordinary people, and only then will it be the turn of the ninja.

Then after the blood inheritance limit transplantation technology matures, it will be the turn of Shizun and Li Chun to transplant their blood.

In other words, Li Chun's blood inheritance limit transplant project is divided into four steps, the first step is ordinary animals, then ordinary humans, then ninjas with chakra, and finally Shizun and himself.

As for where ordinary living people come from, you must know that the most important thing in the Hokage world is thieves.

In the ninja area, Li Chun thinks that Caoyin Village, which is rich in garbage, is a very good supply place.

Three months later, in the laboratory where the root was still located, Li Chun was standing with Mute at both ends of a special medical sealing array this time.

And in the center of the sealing array, a person whose body was firmly fixed to the center of the rune by iron chains was lying quietly.

Then, in each of the two arms and two thighs of the person, a stout injection needle is inserted, and the hose of the needle is connected to four large jars filled with nutrient solution in the distance.

"Are you ready?" Li Chun asked at Mute.

"Alright." Sitting at the end of the rune sealing array, he nodded silently and said.

"So let's get started, the first ninja experiment... The injection is the gene fluid that fuses the blood of the Thousand Hands with the Uchiha. Prepare to open the valves of all the nutrient solution and adjust the delivery volume to the maximum, then observe and record the physical characteristics of the test subject, inject the gene solution, and the experiment begins! ”
