With his outstanding talent for disguise, it is too easy for Kabuto Yakushi to blend into a group of Genin. As a senior who has rich experience in the Chunin Exam, it is easy for him to properly guide the actions of several Genin. As a spy who observes closely, he can appropriately let Sasuke participate in the battle to test the effect of the curse seal. On the premise of ensuring that he passes the exam, he can also give some combat experience guidance.

With the strength of the seven-member team, without the interference of Orochimaru and the One-Tail Jinchuriki, they were already an extremely powerful force. Except for the little trouble caused by the illusion-type ninja in the end, they encountered much smoother results than in the original work, especially after Haruno Sakura and Uchiha Sasuke had experienced similar battles with Mizuki, they quickly found a way to deal with it with their excellent talents. The second Death Forest test was completed much earlier than in the original work.

Not long after, at the place where Sasuke and the Sound Trio had fought, Mizuki, who was cleaning the battlefield, secretly collected some inconspicuous, tattered and discarded rune scrolls and sealing talismans and other things, and completed the mission with satisfaction.

"I hope that this harvest can help me understand something, and it would be best if I could solve the hidden dangers of the curse."

After these days of understanding, Shuimu discovered that the curse was not as simple as he had originally imagined. Whenever he thought about having such a thing in his body that was out of his control, the vague worry could not be eliminated.

"That's the end of the mission. I'm leaving now. I'll do the reporting. You just need to take care of the injured."

After settling everything, Shuimu rushed home.

"We need to deal with these things quickly. If we delay for too long, the sealed chakra will change and it will be troublesome."

In the center of the Forest of Death, after the last batch of qualified candidates arrived, the second exam finally ended ahead of schedule. Without mentioning the hidden dark side, the Third Hokage was telling the candidates who passed the exam the reason and importance of holding the Chunin Exam, and then announced the holding of the third preliminary round, and the examiner and referee was none other than Gekko Hayate. As in the original work, Kabuto Yakushi withdrew from the exam after discovering that Orochimaru, disguised as a jonin, was also present.

The following changes are very minor. If Uzumaki Naruto's passing the exam was largely due to luck, then the rest are all stages for the strong, face-to-face duels without restrictions, and the weaker ones don't have much chance. The only change is the match between Haruno Sakura and Yamanaka Ino. In the original work, Yamanaka Ino let Sakura win, and ended up in a tie with Sakura, and both were disqualified.

The situation was different this time. Yamanaka Ino was accidentally injured in the Forest of Death and was in very poor physical condition. However, Haruno Sakura did not have a big fight with the Sound Ninjas like in the original work, and she was not injured herself. Her condition was much better than Ino. In the duel of wills between the two female ninjas, Yamanaka Ino was the first to collapse and was defeated.

In the end, the number of people participating in the third Chunin Exam was different from the original one. Since it was an even number, there was no need for anyone to fight an extra round. The original Doss was picked out to face Haruno Sakura who accidentally broke into the third exam. The winner will proceed to the next round of eliminations with the winner of Uzumaki Naruto and Hyuga Neji.

At night, Shuimu was very tired after a busy day, after all, his body had not recovered to its full state. After submitting the task report, Shuimu saved the chakra leaked by Uchiha Sasuke's curse seal, tidied the house, ate something casually, and went to bed hastily. Xiaochun was also very busy recently and had not come for the past two days, so Shuimu also lived a very simple life.

Lying on the bed, quietly reading the information on spiritualism for a while, Shuimu suddenly felt dizzy. Feeling a little tired, Shuimu threw down the scroll and thought slowly.

"Spiritualism, there are some problems here."

The summoning technique in the ninja world is more precisely a contract ninjutsu. The more famous ones include the toads, snakes and slugs of the three ninjas, and some less powerful summoning beasts such as the monkey demon of the third generation of Hokage and the ninja dog of Kakashi Hatake. Of course, there are also some summoning beasts that ninjas slowly cultivate from protozoa, but there are no Myoboku Mountain, Ryuchi Cave and Wet Bone Forest for these. There are also some temporary summoning beasts like the jellyfish that Mizuki often uses, which are used and discarded and have little value.

Generally, few people pay special attention to the group of psychic beasts, and only regard them as powerful fighting partners.

Of course, Shuimu does not rule out this idea. For example, Jiraiya is indeed talented, but not so amazing. When Jiraiya was not yet strong, the summoning beast Toad came to help Jiraiya through the most critical growth period and taught him fairy arts that even Orochimaru had not learned. The reason for this is unknown, but it is mentioned that it is related to the prophecy of the Toad Sage, asking him to find the child of destiny. The hidden story inside is not clear to myself as a time traveler, and I am sure that few people in the entire ninja world can understand these things.

However, even so, Shuimu still found something wrong. Apart from the various forms of the summoned beasts and the various unique secrets, there is actually one most important thing that no one has noticed, which is the key process of establishing a contract and summoning.

As for the contract, Shuimu had never seen it before. They were just some common temporary summoning beasts, so he didn't know about the contracts with those powerful summoning beast tribes. But from his memory, the contract should be an exchange agreement with the guarantee of world coercive force. Shuimu would know the gains and losses here only when he saw it himself.

The other one is even more magical. During the process of spiritual communication, the spiritual beast comes through the space and fights for the user. If it can defeat the user, it will fight. If it can't, it can run away. There are very few cases of injury or death.

The two methods of using teleportation and reverse teleportation are too convenient to travel back and forth in this unstable world. This is what makes Shuimu very confused. What worries Shuimu even more is the teleportation practitioner. In most teleportation processes, it involves biting a finger and using blood to teleport. This sentence is mentioned in most teleportation materials: "Use blood as a guide."

Before the rise of science in the past, many religions and philosophers believed that blood was the carrier of the soul. Of course, in the last few thousand years, no one had figured out what the soul was, and blood lost its mysterious veil. But whether this is a problem in the ninja world is worth discussing.
