The original version of the eight-door dunjia temporarily gains powerful power by unlocking the chakra channel that binds the human body. Dozens of times the power above.

But the power of the eight-door dunjia depends on the caster himself, and the strength of the caster increases exponentially, so different people have different powers after opening the eight-door dunjia. After opening the eighth gate—the gate of death, one will also die due to the exhaustion of one's own vitality.

This is a move that releases the body's restriction on chakra and releases excess energy.

In the meridian system of chakra flow, the places that restrain and control the chakra in the body are the "eight gates" of opening door, shutting down door, living door, hurting door, du door, Jingmen, shocking door and dead door.

This eight gates will set a limit on the amount of chakra in the body, but this technique can force the chakra to exceed this limit, thereby drawing out its original strength that is dozens of times stronger.

However, while gaining power, the caster himself will suffer damage, so this technique is listed as one of the forbidden techniques.

Everyone's body has eight doors, anyone can open the eight doors as long as they exercise enough to bear the load of opening the eight doors.

As for who created the Bamen Dunjia, some people think it was the Second Hokage Senshoubojian, and some people think it was created by Matt Dai himself.

However, after Lufa got to know it, he felt that there was no need to over-mythologize the Second Hokage Senshou Feijian.

Because everyone has eight doors, powerful ninjas have enough understanding of the chakra acupuncture points of the meridian system.

Uchiha Madara's understanding of Hachimon Dunjia is taken for granted, and knowing Hachimon may be common sense in the ninja world.

Maybe Matt Dai really figured it out by himself?

After all, apart from the Maitdai family, I really can’t see anyone else who can do all kinds of armor. They can’t have ninja talents, and they don’t have Chakra. Only the Maitdai family, right?

Moreover, with Matt Dai's talent and status in the village, it is completely impossible for him to obtain the forbidden spell in the sealed book.

Therefore, it is very likely that it is a family secret technique of the Mait family, but it was passed to Xiao Li in Maitkai's generation, because Maitkai never found a wife.

The eight-door dungeon formed by Lufa was also created based on the eight-door ninja, and it is different from the eight-door dunjia that is usually closed and opened when needed.

If Lufa's eight-door Dunjia Formation is open, the door will always be open, allowing the body to withstand the output of this intensity.

There is basically no difficulty, and you may die if the next few doors are opened, because you can't make ends meet.

The range of the gates in the early stage is not too outrageous, even if they are opened all the time, they can bear it, and can make the body adapt to this level, and finally turn a person who was originally only a low-level ninja into a middle-level ninja or even a high-level ninja.

In other words, Lufa is a cultivation method that turns Bamen Dunjia into a breakthrough realm.

The first door: open the door: remove the restriction of the brain region, in order to achieve the purpose of exerting 100% of the physical ability, overload the body energy to increase the attack and speed.

The second door, Shuumen: removes the limitation of physical fatigue, overloads the body to restore physical strength, and offsets the fatigue caused by the energy consumption speed of opening the door.

Opening these two doors is equivalent to the level of body skills and chakra of ordinary people ~ ninja level, and because of the adjustment of the road method, it becomes similar to the breathing method, and can re-inhale the dissipated energy through breathing, although it is possible There is still loss, but it is acceptable.

After it is turned on, it may be weak for a long time, but after passing the weak period, the body is equivalent to being strengthened once, and the amount of chakra will also increase.

The third door: Shengmen: further increase the attack and speed, the body begins to congest and turn red, the last safe zone of the Bamen Dunjia, the body begins to emit green energy.

The fourth gate: Injury gate: further increase the attack and speed, the body begins to suffer damage, and enters the danger zone of the eight-door dunjia, and truly enters the state of the eight-door dunjia.

Similarly, because of Lufa's adjustment, the body will not emit green energy, and those energies will be locked up with the breath and the further breathing of the pores, and the loss is negligible. Lufa always feels that it is gushing out. Energy is the most wasted place of Bamen Dunjia, those energies can't be wasted, they are all useful.

Open the third door, and you will have a physical level and chakra level comparable to Chunin. Even if you don't know ninjutsu, you can exert amazing destructive power with a punch or a kick.

After these two doors are opened, there will also be a long period of weakness, which is longer than before, but after adapting, the strength will become stronger, and even become normal, so as to exert a higher level and strength, Go beyond your limits with ease.

Then these two gates are actually a watershed. If there is really no way to adapt, then the period of weakness will remain, and only half of the strength can be exerted, and because the four gates will never be closed after being opened, this kind of Weakness is like Hatake Kakashi's inability to close the kaleidoscope Sharingan, resulting in a very weak.

In the end, because of the injury, it is very likely that he will become sick from overwork and become short-lived.

According to Lufa's own deduction, the weak period of opening the door may be one month, the weak period of shutting down the door is about two months, the weak period of Shengmen is four months, and the weak period of hurting the door may be sixteen months , and possibly forever.

The Fifth Door·Dumen: The speed is enough to drive the air to shake the ground when moving.

The Sixth Door·Jingmen: You can let yourself enter the half-open buffer state, that is, maintain the green energy emitted after opening the door but the state of the body without any changes, so as to reduce your own consumption load and damage, and you can instantly fight when needed fully open.

Once these two gates are opened, or even just open the Du gate, they have the strength of the ninja level, but because of the seriousness of the partial science, it can only be regarded as a special ninja, and the real jnin or even the elite must open the Jingmen Jonin.

Dumen's weak period is 256 months, which is equivalent to a full 21 years, plus the previous weak period, it may take more than 22 years.

But if you say that twenty-two years can make a ninja who is impossible to become a top ninja, or even a ninja who will always be a low ninja or even a middle ninja, become a special top ninja, then it is estimated that 99% of people are willing to practice this forbidden technique.

It's even the kind of people queuing up to grab it, crying and yelling to post it upside down, for fear of missing it.

It can be said that the Bamen Dunjia created by Lufa can be called the gospel of a lot of useless ninjas.
