In the entire ninja world, there are many ninjas who use blood to help perform ninjutsu, but there are very few ninjutsus that must use blood as a medium.

As a part of the body, blood is a very good material for chakra conduction. Generally, the rune materials for depicting seals, enchantments and formations contain more or less the blood of beasts and even humans. When Mizuki uses spiritism, because the IQ of jellyfish is too low, in order to strengthen control, he often uses his own blood to strengthen the connection.

Another typical one is the ninjutsu that stimulates the overdraft of the body, which squeezes blood or other parts of the body extremely seriously.

In addition to the above methods, there is another type of sacrifice, the most famous of which is the flying section of the Xiao organization. The death of the dead priest who sacrifices his own or other people's blood is a very strange and evil spell.

Regarding the principle of psychics, Mizuki doesn't know if there is any similarity with this type of sacrifice, but look at the worm manipulation of the oil girl family, which is to exchange its own chakra and use the body as a worm nest in exchange for the help of worms The Secret Art of Combat.

So in general, unless the psychic beasts are extremely weak like Mizuki, it is hard to say that there will be psychic beasts coming to help fight without any cost.

What's more, the advanced psychic beasts are all intelligent species, and the best among them, such as the toad fairy, the snake fairy and the slug body, are all creatures standing at the top of the power in this world. Without any demands, how could it be possible to intervene in the struggle between humans, even if Kaguya Otsutsuki is resurrected, enslaving all humans with infinite moon reading, and turning them all into Bai Jue, what does this have to do with them? Toads still eat worms, and snakes still eat frogs, so why bother to predict the child of destiny?

If it is said that which one needs to sacrifice what to use is the most famous, it must be the ghoul seal. Only by devoting the soul can the unidentified death **** be summoned to attack and seal the soul.

And spiritualism, as the name suggests, can be understood as a ninjutsu that communicates certain existences. Although it is not the same as the ghoul seal, the principle is somewhat reasonable. The only thing I don't understand is what the psychic beast got from humans? Or…

"Did you not get any benefit directly from humans at all, but indirectly benefit from this world? If this is the case, it is somewhat possible, but I can't say for sure without seeing the real contract scroll. 』

Thinking of this, Shuimu picked up the psychic data again and looked at it for a while, but found nothing.

"It seems that we still have to do some real investigation, so we can't draw conclusions easily. 』

…

The next morning, Shuimu looked at Zhuli, a copycat who was still recovering from his injuries. The situation was basically stable and there was no danger. In fact, for this escape, the violent version of space teleportation was tested, and it was also a last resort.

Before the copycat Zhuli was made, the psychic technique worked, but now it doesn't work. After careful inspection, it is easy to find the reason, because psychic is a ninjutsu between two individuals, but now the psychic contract recognizes Since he and the copycat Zhuli are the same person, general psychic techniques will not work, and at most, use some means to strengthen the perception connection between the two. If it weren't for this, Mizuki wouldn't have to rush to develop any space ninjutsu, but I really didn't expect the real space ninjutsu to be so difficult, completely beyond expectations, so I was very concerned about the ninjutsu that realizes space teleportation. . At this time, Mizuki really realized how powerful the technique of flying thunder god, which can develop space ninjutsu based on inverse psychic.

In Konoha Hospital, many injured candidates are receiving treatment inside. In fact, Shuimu, who has no task for the time being, has not been disturbed by many people. In the coming and going wards, there are occasionally people who are dead with their faces covered and carried. Going out, several of them were rescued by Mizuki himself.

When I came to the intensive care unit on the top floor, Kakashi was already waiting.

"What's wrong with calling me here? Kakashi?" Mizuki asked after entering. In the blink of an eye, I noticed that there were still a few Anbu on guard.

"As you can see, Sasuke is seriously injured," Kakashi motioned, "but I have to take the third Chunin exam in a month. I need to give Sasuke some special training, which is also a kind of protection. ."

"So what?" Shui Mu asked in confusion, "Aren't you here to show off your teacher-student relationship?"

"Listen to me," Kakashi explained patiently, "It has taken a long time to protect and train Sasuke alone, but all three of my students have entered the third exam."

"Oh, I almost forgot to congratulate you, Konoha technician, for your good teaching."

"Cough, let's not mention this for now." Kakashi said embarrassedly, in fact, apart from some basics, Kakashi really didn't teach too many things for newbies, "So my other two students have nothing for the time being. In the third exam, targeted improvement is necessary, so I asked Ebisu to make up for Naruto, who has the worst foundation."

"Oh," Mizuki understood after hearing this, "You want me to help you train Sakura, right?"

"Yes, please help."

"You must have made a mistake," Mizuki refused. "Ebisu is a special Jōnin with a teaching expertise. You can just ask him. What's the matter with me? It's not wrong to say that you are biased."

"Don't be too busy to refuse," Kakashi explained. "In the last preliminaries exam, Sakura guessed that it was the village test, so she asked me who the examiner was."

"So you betrayed me?"

"It's not a betrayal," Kakashi said. "Sakura herself asked you to guide me."

"Oh?" This is strange. "What's the use of looking for me? Her opponent is the strongest Yin Ninja. The gap is too big. Does she have any other ideas?"

"I don't understand the girl's mind, but I really can't find someone suitable to teach Sakura."

"So you pulled me to make up the numbers?"

"It doesn't count. With your strength, sealing techniques, enchantment techniques, illusion techniques, etc., Xiao Ying can't learn much advanced skills at present. There is not much difference between teaching you and me, and the others are not for the time being. Law quickly increases her strength."

"Sealing and illusion are barely the same. What's the use of learning enchantment, it's better to take more rest to save physical strength, the other party's sonic attack is too troublesome."

"I'll leave this to you anyway. Sakura can learn whatever she wants. You can decide."

"Since it's for this sake, it's okay, but~" It's okay to sell personal favors, but if you can pay it back right away, it's also a good choice.
