It takes three days for ordinary adults to transform into a lower-level ninja chakra, a week to transform a medium-level chakra, and a month to transform an upper-level chakra, and ordinary people's physical energy and spiritual energy are too small, even in the plundering way of chakra transformation spell marks, it takes a lot of time.

The increase in strength and speed of the three levels of chakra transformation spell marks Zhou Yu has not been measured, and the prisoners who have gained the power are no longer honestly cooperating, they have all been suppressed by Zhou Yu, but it doesn't matter if they are all for cannon fodder anyway, they don't need to be too fine, just know that they are useful.

The principle of equivalent exchange, through the chakra transformation spell seal to get the chakra for no reason, naturally has to pay a great price, and the body energy is extracted from there? Cells! Cells that have not been exercised, how can they withstand the savage plundering of the chakra transformation spell mark, the more times it is directly the loss of vitality, the spiritual energy is more troublesome, and the squeezing is even more powerful, and the upper ninja level chakra transformation spell mark ordinary adults will not use it a few times, I am afraid that the vitality will be squeezed out.

There is still a big difference between Zhou Yu's chakra transformation spell mark and the big snake pill's curse mark, the more advanced point of the big snake pill spell mark is to transform natural energy for his own use, Zhou Yu's is to cultivate cannon fodder, and it is enough to gain strength by squeezing himself.

Version 1.0 of the assembly line subordinate manufacturing officially appeared, and the 1.1 and 1.2 that were added to the soul storage spell mark in conjunction with the replenishment of the body.

In order to make the assembly line, Zhou Yu's subordinate spent seven months, and after some experiments, the six years were coming to an end in a blink of an eye, Zhou Yu was about to graduate, and he was about to leave after graduation, and suddenly Zhou Yu was still a little reluctant, after all, he had lived in Konoha for six years, and there was also a so-called bond.

Originally, Zhou Yu also wanted to leave something to commemorate Naruto and Sasuke, but he found that he seemed to have nothing to give, and the ninjutsu and sealing techniques created by his proudest research room, but Naruto and Sasuke couldn't use them at all, they all had their own paths, and Naruto and Sasuke didn't need to learn the sealing technique, and in the end, they would just be able to seal Kazuya with a ground-bursting star, and they couldn't hand over the Zhou Yu they needed.

Zhou Yu is indeed a little reluctant to leave the Hokage World, there is still a lot of room for development in the Hokage World, just like the Reincarnation Eye, of course, this is not for himself, Zhou Yu has always insisted on the purity of the bloodline, but it is used to refine things like magic weapons, and the magic weapons refined by the Reincarnation Eye should probably be very strong! However, Zhou Yu didn't have the courage to rob the long gate, first of all, he didn't mention the question of whether he could beat or not, how many people guarded the long gate, and the black absolute and bringing soil were enough for him to drink a pot.

"Naruto and Sasuke are graduating!" Zhou Yu, Naruto, and Sasuke gathered together to lie on the Hokage Rock and chat.

"Haha, Haha, we'll be ninjas soon, one step closer to the Hokage." Naruto is very excited about graduating to become a ninja.

Naruto, we're on a sad topic now, can we not laugh so happily, but Naruto didn't know that he was leaving, and Zhou Yu forgave Naruto.

Sasuke didn't join the discussion between the two, and he didn't know what to think when he was alone.

Looking at Sasuke, except for something related to Itachi, Zhou Yu couldn't think of anything else, alas! Zhou Yu can't do anything about these two brothers, but I'm afraid that Itachi's body won't be killed by Sasuke, and I'm afraid it won't last long.

In the future, Zhou Yu can't help much, but now Sasuke, Zhou Yu can still help, and gestured to Naruto, to deal with Sasuke who was depressed, Naruto is the best healing medicine, and sure enough, Naruto came out to fight one.

"Now the graduation exams begin." Early in the morning, Iruka announced, "The person who was called went to the next classroom, and this exam was a doppelganger." ”

"Doppelganger, haha, I'm the best at this." Naruto exclaimed excitedly.

"Nara Shikamaru." Shikamaru was the first to shout.

"Cut, the trouble is dead." No matter how to complain, Shikamaru still honestly went to the next door to take the exam.

Next, Naruto, Sasuke, and Sakura were all named in turn.

……

"Zhou Yu."

Oh, finally being himself, originally Zhou Yu could have left at this time, but Zhou Yu didn't want to leave regrets, it could be regarded as a souvenir, Konoha's forehead guard was a kind of memorial to the Hokage world!

"Iruka-sensei, Mizuki-sensei." Zhou Yu greeted politely, and Zhou Yu couldn't help but think that without Naruto, who would Mizuki choose? But who you choose doesn't have much to do with you.

"Yu, you can get started." Iruka said.

"Hmm." , Zhou Yu sealed, 'doppelganger technique. ', 'bang', 'bang', two sounds, Zhou Yu perfectly divided the two clones.

"Qualified." Iruka announced.

"Thank you, Mr. Iruka." Zhou Yu stepped forward to take the forehead guard.

"Haha, Yu you also passed."

"Stupid, Yu, how can you not get through."

"Oh, yes! Haha, but it's nothing, Yu, let's go celebrate!" Naruto suggested.

"Okay!" It's also a loose meal!

With Sasuke's place, two were naturally sent, and the celebration of the three became the celebration of ten people, and later Xiao Li and the three of them also came to congratulate Zhou Yu on his graduation, and they all joined in, this should be the first dinner party of the twelve Xiaoqiang!

The place for the dinner was chosen at a barbecue restaurant, and most of the barbecue meat was also in Dingji's mouth, and Naruto was still unconvinced and played with Dingji, but he was defeated.

After the celebration, Ning Ci had a fight with Naruto and Sasuke when they met for the first time, and proposed to have a competition, Xiao Li was also eager to challenge Zhou Yu, a senior brother, and Zhou Yu, who was originally going to watch the trouble, immediately refused on the grounds that he was too full to eat and not easy to fight.

The battle was not finished, the time was not early, and everyone went back.

"Zhou Yu, Lord Tuanzang, please" Zhou Yu was stopped on the way back.

"Oh! Is there a limit to flying the Thunder God enchantment?" Zhou Yu asked, the root people didn't answer, just looked at Zhou Yu, do you go or not, the root people were told by Tuan Zang not to use strong before they came out, Tuan Zang was afraid of using strong Zhou Yu and ran away.

After two years of waiting, Tuan Zang got Orochimaru's reply that 'it still takes time', seeing that Zhou Yu was about to graduate from the ninja school, and there was no chance if he didn't do it, Tuan Zang had no choice but to plan to control Zhou Yu with the kaleidoscope illusion of stopping water, and then add a spell mark.

Zhou Yu followed, originally just wanted to leave quietly, but since Tuan Zang sent it to the door, he accepted the 'gift' himself, Tuan Zang's right hand is also a good thing, ten three-hook jade writing wheel eyes, should be able to refine a lot of surprises! Anyway, if the group is moved, it won't have a big impact on the back, and the later plot doesn't need to be promoted by the group, and the Five Shadows Conference can go with or without hands.
