In the days that followed, Hinata Mitsuko spent the day practicing physical skills at the ninja school.

In order to get the body closer to the limit and adapt to the limit faster, he almost always maintained the state of opening the "door opening" and "retirement door" during exercise.

If Kai knew about his training, it would definitely make Kai dumbfounded.

Because even if the "open door" and "Xiaomen" are just the first two doors in the "Eight Gates Dunjia", the burden on the body is also very large. There is no problem to open it in a short time, but if it is maintained for a long time, it is not something that ordinary people can do. This is not a problem of not working hard, but the body of ordinary people cannot withstand such consumption.

Of course, Hinata Mitsuki, who has the eyes of reincarnation, is not an ordinary person, so although this exercise method is crazy, he can barely grit his teeth and persevere.

And this almost inhuman ascetic practice brings very obvious effects.

On the afternoon of the fifth day of asceticism, Hinata Mirror successfully opened the third door of the "Eight Gate Dunjia" located in the throat, which was a day and a half earlier than expected.

But when Xiang Jing found Kai and asked about the opening skills of the fourth door "injury door", Kai told him that Kakashi had also come to ask in the morning.

"It's actually half a day faster than me!"

After learning that Kakashi had also come to ask, Hinata was shocked.

In order to master the "Eight Gate Dunjia" as soon as possible, his cultivation these days has been "crazy", but even so, he was still behind Kakashi for half a day, which shows how hard Kakashi worked.

Kaize sighed: "It took me three years to open the 'life gate'. You two guys mastered it in less than a week. Compared to you, I am simply an idiot."

Hinata shook her head: "It can't be calculated that way. Your three years also included basic training. At that time, Kakashi and I were also training? If you have the current foundation and then begin to learn the "Eight Gate Dunjia" at this time, the door opening speed will not be much slower than us!"

Kai showed a row of white teeth and smiled, "You don't need to comfort me. Challenging you geniuses is a very interesting thing, and I enjoy it!"

Hinata also knew that Kai was a guy with a strong mind, so she didn't say anything more. After asking about the skills and precautions for opening the fourth door, she said goodbye.

When he returned home in the evening, Hinata Mitsuki came to the bedroom, closed the doors and windows, took out a roll of storage reel from his ninja bag, and then took out something out of the reel.

These things include the meridian diagram of the human body, the sealing information, and many unfinished manuscript papers.

Hinata Mitsuki's daytime belongs to the "Eight Gates Dunjia", and at night, when he returned home, he began to study the improvement of the "yin seal".

Finally, the Fire Escape Clan was also taken out from the storage scroll and placed it on the side. Hinata Mirror was studying the Fire Escape Clan while comparing the human meridian diagram, and revised it on the manuscript.

If he encounters a problem, he will use the "Soul Arrival Technique" of the reincarnation eye to let the spirit enter the Fire Escape clone, control the Fire Escape clone to personally feel the trajectory of the running of chakra in his body when he launches the "yin seal", compare the meridian diagram of the male in front of him, find out the differences in the subtleties, and then mark them one by one.

It is not easy to improve the very perfect secret technique of "yin seal".

Fortunately, Hinata Mitsuki has a fire escape clone that successfully mastered the "yin seal" as a reference. In addition, his requirements are not high, and he just wants men to practice the "yin seal" smoothly and obtain the magical effect of the "yin seal" accumulated chakra, so if you take the target, there is no clue to improving it.

After five or six days of meditation, Hinata had a preliminary plan in his mind.

According to the trajectory of the chakra when the Fire Escape clone activated the "yin seal" and after comparing it with the male meridian diagram one by one, he found that there were more than a dozen subtle differences between the two.

It is precisely these dozen subtle differences that have caused male ninjas to be unable to practice the "yin seal" smoothly.

According to normal improvement routines, Hinata Mirror needs to conduct a comprehensive analysis of these dozen subtle differences one by one, as well as various supporting verification tests for design.

However, the human meridians are not wonderful, and any small differences are enough to make people study repeatedly, so Hinata no longer has the energy and time to analyze the subtle differences in these dozens of places one by one.

If someone else is changed, you will be helpless at this time.

But Hinata Mitsuki is different. He has the most biological cloning technology in the ninja world, so he came up with a very simple solution, which is trial and error elimination method!

Simply put, it is to use more than a dozen clones to try and make mistakes one by one. Anyway, the clones are controlled, so there is no need to worry about the irreversible damage caused to the body's meridians after trial and error.

Through this method, we can find out which of these dozen subtle differences, or which differences are as fast as possible, which creates obstacles for men to practice the "yin seal".

As long as these obstacles are accurately identified and the sealing skills of Hinata Mirror can be solved one by one, it will be a matter of time.

In these days when Hinata Mirror practices hard day and night, there is no peace in the ninja world.

Just as Hyuga Mitsuki expected, the riots broke out in Yunxi Village soon spread throughout the ninja world, and their spreading speed was even beyond Hyuga Mitsuki's expectations.

As the turmoil in Yunyin Village spread, some real and fake news also spread in the ninja world.

One of the news attracted the attention of Hinata Mitsuki, that is, there was a rumor that there was a big problem with the hiding of the ritual. Although he successfully obtained a variety of "blood transcendence limits", the most critical spirit body had problems, and many souls appeared in his body that could compete with his deity for control of the body.

At first, Hinata thought the news was spread from Yunyin.

But if you think about it carefully, Yunyin will never easily leak such important information. You should know that Yunyin still blocks the truth about the riot in Yunyin Village and blocks the news that they have contact with Konoha Rebellious Ninja Group, so this information is unlikely to flow out of Yunyin.

"Is it Orochimaru?"

Now, besides Yun Yin and Hinata, there are only Orochimaru who were also present at the time. If it weren't Yun Yin, then eight out of ten would be Orochimaru.

"But Orochimaru doesn't have this motivation either! And if it weren't for Orochimaru, who would it be?"
