Zhou Yu excitedly controlled the soul on the plane of the soul research pillar, Zhou Yu didn't expect that as a former scumbag, he also embarked on the road of scientific research, or a high-end subject like the soul, and sure enough, cultivation changed fate.

Zhou Yu has long been troubled that he has no method of cultivating the soul, and the improvement of the soul can only be increased by time, but if he only relies on the soul to grow by himself, and does not find other ways to speed it up, he is estimated to be left behind in this life, and the soul himself will not grow indefinitely, and his mortal body is estimated to be the soul will not grow after adulthood. The poison's invasive body directly needs to find the world to cultivate, so Xiao Zhi helped him apply for a body that returns to the original to the age of six, and the body goes back, but the soul and spiritual power do not go back, and they have undergone secondary development, because the level of the Hokage world is much higher than that of the earth, the secondary development has become a high-speed development.

How important is the soul, spiritual power is the most superficial manifestation of the soul, and how many aspects of spiritual power are affected, chakra refining requires spiritual energy, and one's own future magic learning needs spiritual power, and a strong body must also be equipped with a strong spiritual power control.

The secondary development of the soul made Zhou Yu not feel that his mental power was insufficient, but when he reached adulthood, his secondary development stopped, and if he didn't worry about it now, it would be too late to become an adult in the future.

Plundering other people's soul energy and increasing one's own soul energy was Zhou Yu's simplest and most brutal method.

Zhou Yu encountered difficulties in refining soul energy, and he didn't know anything about the soul how to refine the soul energy that greatly replenished himself.

"Ash, what good advice do you have?" Zhou Yu asked Xiao Zhidao.

"Nope."

"Oh well! It's still up to me. ", 'Smack', Zhou Yu casually smashed the soul on the plane of the soul research pillar, I don't know if I started with it, then smash it and slowly get it done.

Xiao Zhi saw Zhou Yu's bag storage behavior, and the corners of his mouth twitched obviously, that is the soul, isn't it your walnuts that can be eaten if they are broken.

Looking at the soul that was not completely broken, Zhou Yu manipulated the sealing technique and slapped it a few times, the soul of the lower ninja level was completely smashed by Zhou Yu, and the broken soul became a ball of flowing energy, the following is to be separated and purified, Zhou Yu doesn't think that the soul can be used directly if it is broken, if he dares to use it directly, I am afraid that it will not be long before he will become a madman!

Manipulating the soul sealing technique depicted on the plane of the soul research pillar, forming a very thin transparent thin line, one of the great achievements of Zhou Yu's soul sealing technique, and also one of Zhou Yu's reliance on the soul research, the soul cutting line, it sounds very **, and it is also one of Zhou Yu's killer features, the soul attack is much more high-end than the attack on the physical energy, and a wound in the soul is fatal.

The principle of the soul cutting line is very simple, as long as there is a super high and super high chakra control, the chakra is controlled to form a fixed line, and the special technique of the soul is formed by caring about the fixed line of chakra as the carrier, and the soul cutting line is further formed, and the soul cutting network is further on, of course, the immortal chakra is also OK, the soul cutting line and soul cutting network of the immortal chakra can be stronger, and the soul of the lower ninja level is enough to solve it with the chakra soul cutting line.

The transparent soul cutting net struck up and down the smashed soul a few times, and it was cut into small soul energy clusters, and thousands of tiny soul energy clusters floated on the plane of the soul research pillar.

Zhou Yu began to study the thousands of small soul energy groups, which ones are harmful to the soul, those can be used in purification and purification, I feel that if there is still a mixture, it will be cut up and down a few times, and some of the thousands of small soul energy groups have been cut by Zhou Yu several times, and after cutting, it is classified, Zhou Yu's soul energy is roughly divided into three types of gray soul energy groups, transparent soul energy groups, and black soul energy groups, of course, these three types of soul energy groups are not pure, they are all mixed with each other, The next step is the problem of purification, of course, before purification, it is necessary to test what each of the three souls can be? What's the use?

When he returned to the root lair, he asked the root people to find the link with Orochimaru, Yakushidou.

"Danzo-sama." Yakushidou soon reached the ground of the roots.

"Inform Orochimaru that I need the Reality Flying Thunder God's enchantment, and in exchange I will tell him the route of the next time that kid from the Uchiha family leaves the village." Danzo knew that he couldn't summon Orochimaru without paying a price, so he just used Orochimaru's hand to get rid of the last Uchiha Sasuke of the Uchiha clan.

"Yes, Danzo-sama." Hearing the light in the eyes of the Flying Thunder God Restriction Enchantment Dou, the spy genius Dou naturally knew the information of Zhou Yu, who was very close to Sasuke, and was an absolute genius-level person.

Half a day later, Dou's team took over the storage task.,Dou also left the team halfway.,Dou's teammates are all spies from the sound ninja village.,The instructor is also a member of the group.。

Two days later, Yakushidou came to Otoshinobi Village and found Orochimaru.

"Orochimaru-sama."

"Why are you here, what do you want to cooperate with in Tuanzang?" Without his own summoning, it can only be the message that the old man wants to deliver.

"Yes, Orochimaru-sama, Danzou wants Orochimaru-sama to research an enchantment that restricts the flying thunder god, and as a trader, Danzou will tell you about Uchiha Sasuke's whereabouts next time he goes out of the village."

"Flying Thor?" As Orochimaru, who aspires to learn all ninjutsu, Flying Thunder God has always been a pain in Orochimaru's heart, "Dou, do you know why?"

"It's for a person named Zhou Yu, this person can fly the Thunder God Technique, and Tuan Zang should want to capture this person." Dou explained.

"Konoha is a new genius? It's really nostalgic. ”

"Orochimaru-sama needs to pull this person into the pre-candidate as well?"

"No, no ninjutsu can compare to those eyes, what if you can fly Thor, it's not that you are defeated under those eyes." I have to say that Orochimaru's dedication to writing wheels has been a little enchanted, and Itachi's lesson to Orochimaru is too profound.

"Always pay attention to Sasuke Uchiha's movements, the day of harvest is not far off." Orochimaru is already preparing that plan, the Konoha collapse plan is not something that can be achieved by discussing it with Sand Hidden Village a little before the middle ninja exam, it takes a lot of preparation work before, it takes a long process to trust each other, and it also takes a long discussion time to divide interests after the war, of course, Orochimaru didn't think about any post-war benefits, and Orochimaru's purpose is not for this, but in order not to be suspected by Sand Hidden Village, Orochimaru can only pretend to discuss the distribution of benefits after the war with the people of Sand Hidden Village.
