"Pocket, it will take time to recover from Tuanzang." Flying Thunder God Orochimaru not only studied, but also studied for a long time, and did not study it thoroughly for a long time, and then Orochimaru was fascinated by eternal life, so he gave up Flying Thunder God research.

Tuan Zang now wants him to study the restriction of the Flying Thunder God enchantment to the Great Snake Pill who will not fly the Thunder God is a very time-consuming thing, and even after a long time of research, there will be no results, the Great Snake Pill now attaches the most importance to immortality and writing wheel eyes, how can there be time to play with Tuan Zang, so Tuan Zang is doomed to tragedy, left and right and other Great Snake Pill's limited space ninjutsu enchantment, and the answer to the wait is only time, when the last Tuan Zang and so on lost the last bit of patience and prepared to design Zhou Yu again, Zhou Yu only left a place of dust for Tuan Zang, Drift away.

It's not the time when it's Konoha now, when research needs to be supported by Danzo, now? It's just that there is still use value, and Orochimaru perfunctory Tuanzang, Tuanzang only thought that if he pinched Sasuke's lifeline, Orochimaru would be obedient, but if Orochimaru was the kind of person who would be obedient and obedient, he would not do anything to experiment with ninjas in the same village under the education of three generations.

"Yes, Orochimaru-sama."

Of course, Yakushidou didn't leave there, Yakushidou stayed in Otoshinobi Village to assist Orochimaru to do a lot of research.

Looking at the three types of soul energy, Zhou Yu was thinking about whether to secretly go out of the village to study, the three groups of soul energy in black, gray, and transparent colors can only know the effects of the three soul energy if you find someone to experiment.

Zhou Yu went out of the village and was worried about meeting the Hyuga clan outside the village, although the attack power of the white eyes in the three major eyes was not high, it was absolutely accurate to recognize people, and it was useless to use the transformation technique to meet the white eyes, everyone Chakra has their own special color, and he and the Hyuga clan also had some causal entanglements, who knows if the Hyuga clan has seen themselves with white eyes, if they are found outside, I am afraid that they can really only admit it, and the trouble will be big, Zhou Yu is purely a thief without a thief's courage, he wants to gain and does not want to take risks, he hates himself.

But in the end, the desire to study overcame his fearful thoughts, and he went out of the village to experiment, of course, Zhou Yu would prefer those who did a lot of evil.

If you want to go out to experiment with a low-level ninja soul, it is obviously impossible to meet the needs of your experiment, and Zhou Yu separated a few more low-level souls.

Leaving a shadow clone to watch Zhou Yu used the Flying Thunder God to go out of the village, the best research material is, of course, a bandit, and there will be no burden to do evil as experimental material.

The moon is dark and the wind is high, of course Zhou Yu is not going to kill, Zhou Yu will not just take away a few bandits to find a place to start experiments, the soul experiment is a long-term life, and he can't exist every day to guard those thieves who are imprisoned and experimented by himself, and the shadow clone can't be sure of 100% insurance, the reason why the accident is unexpected is because it was very accidental, Zhou Yu chose a milder experiment, and quietly integrated the three groups of soul energy into each of these thieves when they slept, as long as they came to observe their condition every day.

Zhou Yu selected thirty bandits as a target, ten people from each type of soul energy group, and it is impossible for the bandits to refine their own soul energy, Zhou Yu can only integrate the three soul energies into the souls of the thirty bandits through the soul sealing technique, the three soul energies are not the end of a fusion, and the effect may not be seen if the amount is small, and the effect can be better if the three soul energies are often integrated into the bandits.

Zhou Yu also painted a portrait of the thirty bandits, and the daily changes must be recorded, all of which are important data for their own analysis in the future, and the soul research can not go a little wrong, otherwise it will be unlucky to be himself, Zhou Yu found two cottages respectively, and each cottage is also taken from the thirty thieves for research, and the three cottages are still very far away.

In the days to come, Zhou Yu would go to the three cottages every day to record the situation of the ninety bandits, and give them the fusion of different soul energies.

After Zhou Yu fused the ninety thieves with different soul energies day and night, the ninety bandits finally changed, the people who fused the black soul energy group became more and more murderous, and the killing became more and more serious, and the people who fused the gray soul energy group became more and more divided, and often appeared to think that it was another person, and the person who fused the transparent soul energy group was the most normal, at least more normal than the bandits who fused the other two soul energies.

In the end, the person who fused the black soul energy group completely became a killing machine, only knew how to kill, and there was no other consciousness at all, the person who fused the gray soul energy group was completely split and crazy, and the person who fused the transparent soul energy group was still normal after the other two kinds of thieves had problems.

The different fate of the three soul energy fusion people Zhou Yu also probably has some judgments, the black soul energy group should be the evil qi produced by too many people killed by those lower ninjas before their deaths, and the people in the Hokage world do not know how to eliminate the evil qi naturally gather more and more, Zhou Yu will recite the heart without distractions several times after each time, Buddhist and Taoist classics are sometimes read, sublimating and sublimating the soul, and also seeking self-comfort, the gray soul energy group should be the memory fragments of those lower ninja before their deaths, The transparent soul energy group should be the soul energy essence that you want to find that can absorb without any trouble.

After coming up with the transparent soul energy group that can be fused and absorbed, Zhou Yu did not rush to fuse, Zhou Yu still had to observe and observe, there is no trivial matter in the soul, and it is not too careful to be careful, otherwise he is now in a hurry to fuse, and the soul has been improved, but if something goes wrong, it will be a big problem, and it is no wonder that others, who called themselves too anxious at the time.

For a month, two months, Zhou Yu was there to observe the thirty bandits who fused the transparent soul energy group in the three cottages, and slowly those bandits who fused the transparent soul energy group also began to become irritable and often had nightmares at night.

Zhou Yu knew that the transparent soul energy group could not be fused directly, and it had to be purified, and the transparent soul energy group was still mixed with the black evil soul energy group and the gray memory fragment soul energy group, and it could even be said that the black evil soul energy group and the gray memory fragment soul energy group also contained transparent color fused soul energy group, and the soul cutting line was not completely separated, and it had to be purified with the help of other means.

Zhou Yu was also cautious and glad that he was not in a hurry, and the use of transparent colors could fuse soul energy clusters.

Of course, the experiment has not ended at this point, this is only the first stage to test the three soul energy characteristics, and there are more experiments that need to be done by yourself, I have been fusing transparent soul energy clusters for the bandits before, Zhou Yu needs to verify whether the thieves are causing problems because of the fusion of too many transparent soul energy clusters? Could it be that the fused transparent soul energy mass exceeded its own soul energy that caused the problem? Does the human soul have the ability to purify? Will a small amount of fused transparent soul energy clusters be absorbed by their own soul evolution? This is all what Zhou Yu needs to experiment.

Zhou Yu stretched out his magic grip to the bandits, and the three cottages in the first phase of the experiment were erased by Zhou Yu one by one, not because he was ruthless, but just for insurance.
