The next morning, Hinata Jing arrived at the practice site she agreed with Kai. This was a remote wooded forest near the river. It would be neither disturbed nor far from the village.

Swish...

Before Hinata Mirror could enter the forest, a gust of wind broke out from the forest.

Immediately afterwards, two figures rushed out of the forest one after another, fighting fiercely together, the howling of the fist and the muffled sound of the fist and the intersecting sound of the fist and the foot are heard in an instant.

"Haha, these two guys are really too idle!"

After chuckling, Hinata Mitsuki jumped to a big tree and sat down leisurely.

It was not someone else who fought in the forest, but Kakashi and Kai. Perhaps they had arrived first, so they waited for Hinata Mitsuko while having a daily conversation.

Hinata on the tree took this opportunity to observe the two people in the competition.

Both of them have excellent physical skills and very fast speed. When they shuttled through the forest, they looked like two ghosts dragging long afterimages. If they were replaced by ordinary people, they would not be able to see the details of their fight, but this would not be difficult for Hinata Mirror, who had the reincarnation eye.

With one hand on his chin, Hinata Mitsuki observed and commented: "Kai's moves are getting more and more fierce!"

The steel fist flow ninja actually has no trick to improve their strength. They can only improve their speed and strength through hard training day after day.

Therefore, compared with ninjutsu ninjas, the strength of the steel fist flow ninjas is relatively slow to improve.

But this does not mean that Steel Fist has no future. On the contrary, as long as you can endure loneliness and withstand the hard work, the upper limit of Steel Fist flow ninja is far higher than that of ordinary ninjutsu ninjas.

Kai is a good example. In his contemporary students, except for a very small number of geniuses like Kakashi, the vast majority of people's strength improvement began to slow down significantly when they were in their twenties, and some even began to stand still.

But Kai is different. He was not very prominent when he was in the Ninja School and was left behind by many contemporary students. However, as time went by, his strength was neither too fast nor too slow, and he gradually improved steadily. Instead, he surpassed the previous contemporary students who were better than him. Unconsciously, he grew into a reassuring powerful sun.

He turned his attention to Kakashi again, and Hinata Mitsuki observed for a while, whispered: "Hey, why is Kakashi this guy..."

Halfway through his words, he suddenly became speechless because he found that he could not think of a word that accurately describes Kakashi's current state. Kakashi now gave him a very strange feeling, as if he was at a critical point, or in other words, in some critical transformation.

At this time, after realizing that Hinata Mirror had arrived, the two of them in the competition stopped at the same time.

Jumping down from the big tree, Hinata Mitsuki walked over and said hello: "Hey, you two are so early!"

Kai showed off his big white teeth and smiled, "Mirror, sweating in the rising sun is what youth should look like!"

Kakashi didn't say anything, but nodded ashihito to Mitsuki.

As he approached, Hinata Mitsuki felt more and more that Kakashi had a sharp edge on his body, and his whole body seemed to be like a sharp blade with a burst of cold light.

Hinata couldn't help asking: "Kakashi, are you okay?"

Kakashi shook his head: "I'm fine."

He actually knew what Hinaga Mitsuki was referring to, and he also understood that in order to gain stronger strength, he had changed a lot in both personality and temperament, but he had no regrets because he needed strength to correct his close friends who had gone astray.

Hinata smiled: "I'm really not used to your energetic look!"

Kai also echoed: "Yes, you were always late for dates before. I didn't expect that I came earlier than me today. It really scared me!"

Kakashi had no intention of joking, and saw that everyone had arrived, so he urged: "Let's start."

After the three of them arrived in the woods, Kai put away his smile and said with a serious expression: "'Eight Gates Dunjia' is not so much a forbidden technique or a skill, but rather a habit, a physical habit!"

Starting from the first door "open door" at the middle of the eyebrows, Kai pointed to the human acupoints corresponding to the eight gates in turn, and finally stopped his hand in the heart, which is the position of the eight gate "death gate", and said: "These eight gates are actually the eight hubs that protect the human meridians. Their meaning is to restrict the ninja from over-refining chakra to avoid causing irreversible damage to the body."

Hyuga asked: "The key to practicing the 'Eight Gates Dunjia' is not just to open the eight hubs in the meridians, but to make the body accustomed to opening the overload state of these hubs?"

Kakashi also asked: "The order of these eight gates should be arranged according to the difficulty of physical adaptation, right?"

Whether it is Hinata Mitsuki or Kakashi, they are excellent ninjas who are both theoretical and practical, so they both got a lot of information from Kai's introduction to "Eight Gate Dunjia".

Listening to the questions of the two people in front of him, Kai, who was planning to introduce the "Eight Gates Dunjia" in detail, was choked and opened his mouth, but he didn't know what to say for a long time.

Hinata asked, "What's wrong? We've misunderstood?"

"No..." Kai, who had recovered from his senses, shook his head and said, "You two understand it very well. The core of the 'Eight Gate Dunjia' is to make the body accustomed to opening these hubs. However, there are only the first seven gates that the body can adapt to, and the eighth gate, "Death Gate" located in the heart area, is a taboo gate that must never be opened easily!"

Kakashi asked, "What will happen if the 'Death Gate' is opened?"

Kai said with a solemn look on his face: "Once the 'Death Gate' is opened, the chakra will increase by ten times or even dozens of times in a short period of time. It can instantly allow an ordinary ninja to gain more than the Naruto's strength, but the consequence is death! Because no matter what, normal people cannot bear the huge burden after opening the 'Death Gate', so death is an inevitable result, which is why the eighth Gate is called the 'Tao Gate'!"

After learning about the effect and cost of opening the "Death Door", Kakashi did not feel palpitations like a normal person, but fell into deep thought, as if he was seriously considering on what occasion to open this "taboo door".

Hinata Mitsuki was also thinking.
