Unlike the previous life, the body and soul are inseparable. In the ninja world, with the tool of chakra as an extension of the will, the soul can also get rid of the shackles of a single body to a great extent. In this world where the basic rules are not very stable, it is not surprising that a collection of human negative wills like tailed beasts is born.

Mizuki, who no longer paid attention to the sign at the door, led Sakura into the store.

"Are you going to work here for a while?"

"Work?"

"No, it's learning~" Mizuki really wanted to give himself a big mouth and almost leaked.

Sakura nodded and said nothing.

"Do you feel any difference here?" Mizuki asked.

"To say the difference, it seems that the quietness in the store is a little abnormal." Xiao Sakura looked at the people coming and going on the street outside the door, but the sound that reached the store was very low.

Mizuki nodded and said; "Your attention and perception are very sharp, which may be related to your excellent chakra control. This is a speciality that will be very beneficial to you in the future."

Without explaining more, Mizuki led Sakura to the back of the counter, revealing a small bookcase that was very delicately hidden. Shuimu pointed to the books and various scrolls inside and said, "Don't touch the ones with red labels. I can read the yellow ones when I'm present. Read the rest. You can read as much as you can in three days." I handed out a pamphlet to Sakura, "This is a comparison table and various records I made, most of the things in it have been verified, but it can't be guaranteed to be absolutely correct. If you don't understand, you can refer to it and read it. I'll give you time for questions in three days."

"Shui Mu, is this all right?" Xiao Chun felt a little uneasy, "Kakashi, let the students be handed over to you, and you just let her learn by herself?"

"I'm not watching, don't worry." Shuimu said, "Smart students don't need teachers to worry too much."

"Then I'll leave, and I'll bring you food at noon." Xiao Chun was about to go to work.

"Well, don't forget to bring a copy for Sakura."

With the passage of time, after the morning rush hour, the flow of people in the store gradually decreased. Mizuki glanced at Sakura, who was working hard, with a focused attitude, worthy of being a genius of learning.

Taking advantage of the time, Mizuki also took out the reward that Kakashi gave him, which was the ninja psychic beast contract inherited from the Hatake family.

In exchange for teaching Sakura, Mizuki took this opportunity to take a closer look at what a real psychic contract scroll looks like.

Touching the cover of the scroll, Mizuki exuded chakra slightly, sensing the possible problems inside.

"It's not ordinary paper, it seems to be the skin of some kind of creature. 』

Spread out the long scroll, revealing a series of names and fingerprints. The first thing I saw was Hatake Kakashi. The further I looked up, a long list of people mostly from the Hatake family spread out to the very end, and a psychic formation talisman appeared in front of me.

After studying this psychic contract for a long time, Shuimu didn't find anything special in it.

"Should it be said that it is a psychic beast inherited from the ninja family, it is indeed much more advanced than the ordinary goods. 』

The optimization effect of various rune collocations, spatial perception and connection methods are much more reliable. Correspondingly, the user's chakra requirements are also more stringent. Different chakra amounts and output methods may correspond to different individuals. However, Mizuki still found nothing of value.

"Is there really no problem? The contract is very fair. The consumption of chakra to provide psychic summoning is a little high, but it can be regarded as a reward. From this point of view, it is a model contract of mutual benefit. The surrounding decorative patterns and inscriptions also did not find any traps. It's all normal stuff. Is it really just that he is over-hearted? 』

The unwilling Mizuki slowly stroked the surface of the scroll while thinking. Suddenly, Mizuki's hand froze, and the hand that touched the scroll carefully felt it.

"what is this? 』

There seemed to be some special lines, and Shuimu hurriedly observed it carefully. As his fingers gradually rubbed, some traces of the same color as the original were found.

"This is actually the natural seal rune that comes with the raw material itself. No wonder I can't find it. However, this shape seems to be familiar. 』

After thinking for a while, Mizuki put down the things in his hand, walked out of the store, looked at the signboard of the Four Seasons Flower Shop, and recalled every bit of his own making at this time.

"That's what it is, no wonder. 』Finally, Mizuki clears his eyes a little.

Turning around and walking into the store, Mizuki picked up the scroll again, thought about it, and copied the natural pattern. Then, after checking several times to confirm that there is no missing information, I put it away.

"Although I was unfounded, I was surprised to find out. 』

In this psychic contract, there is actually a rune that is very similar to the function of the collective consciousness group that Mizuki has researched. In other words, according to this contract, the psychic beast has the ability to collect the contractor's thinking fluctuations or spiritual radiation all the time. In theory, this is not harmful to humans. As a person thinks, he will constantly emit some information, which will gradually dissipate in the air even without any treatment. Just like the sun emits light and heat, no matter whether you use it or not, it is there anyway. And the psychic beast seems to be collecting these useless things. In the eyes of ordinary people, this is more useless waste than collecting chakra.

"If they hadn't planned otherwise, then they must have mastered a way to turn waste into treasure. Generally, there are psychic beasts, either controlled by a military organization as powerful as Konoha, or secret skills passed down by major ninja families for hundreds of years. 』

Shui Mu, who was dizzy at the thought, stopped; "The water in here is very deep. It is clear that the things written in the contract can be written in an open and honest way, but they have to be hidden. After a while, we should study carefully what is hidden in this area. Such a treasure."

"Mr. Shuimu, for you?" Suddenly a glass of water was handed over.

"It's Sakura, thank you." Mizuki took it and drank it, feeling more energetic.

"You're welcome, I didn't expect the teacher to be like this." Xiao Ying said with a smile.

"Oh? Then what do you think a teacher should be? Yelling like Iruka?"

"No, I just think that Teacher Mizuki is more knowledgeable than I imagined," Xiao Ying said quickly, "After reading the things that Teacher has studied, I can only memorize many of them first, but I don't understand most of them."

"That means you can still understand a small part of it?" Mizuki comforted, "It's much better than I imagined. Every ninja's private research has its own characteristics. Without the accumulation of pre-knowledge, you can know what you are learning. Anything is fine."
