Blood-resistance boundary is a technique that can only be inherited by blood ties through genes under normal circumstances. Usually, except for people with the same bloodline, others cannot learn it, and even if they use Sharingan, they cannot be copied. Here, the blood-resistance boundary that the world wants to practice is a kind of escape technique.

There are risks in practicing the blood-resistance boundary. This details the so-called risk in the Uchiha clan's art ritual room, which is blood-resistance disease. In other words, it is genetic collapse and a terminal illness of ninjas. In the Uchiha clan's research, the statement that chakra equals soul equals genes is officially established. Combining the changes in the two chakra attributes can give birth to new attributes. This new attribute chakra will cause a huge change in genes. If you can survive this gene change, then congratulations! You will have your own blood-resistance boundary, and this blood-resistance boundary can also be passed down with the inheritance of the bloodline. If you don't survive, then sorry! You will be destined to die in the blood-resistance disease.

The basis of the blood-resistance limit of escape techniques is the five attributes of wind, thunder, water, fire and earth.

The Uchiha clan divides all the blood-resistance boundaries of the Ninja Realm into two categories. The first category is called "extreme type" and the second category is called "compound type". Let's talk about the "extreme type" first. Because the last bloodline of the Baishui clan is killed by the world, the Uchiha clan does not have to worry about the revenge of the Baishui clan, so she just obtained the corpse of the Baishui tribe of the Three Ways and also got some secrets of the Miao escape. Although the Miao escape of the Baishui clan only involves a change in the chakra attribute, that is, the water attribute. However, the power it shows far exceeds the water escape itself. The world uses this single attribute to the extreme and far better than the original attribute, and calls it the "extreme" blood-resistance boundary. Although her blue fire escape is far higher than the original fire escape, it has no changes in essence, so the world does not classify the blue fire escape into the category of the blood-resistance boundary.

After finishing talking about the "extreme" blood succession limit, let's talk about the "compound" blood succession limit!

"Compound" blood-resistance limit refers to a new attribute chakra that combines two chakra attributes, thereby resulting in a new attribute chakra. If the chakra intensity of the five attributes is set to "1", then the chakra intensity of the "extreme" blood-resistance limit is "2-3", while the 'compound' blood-resistance limit is "4". At present, there are eight types of "compound" blood-resistance limit recorded by the Uchiha clan, namely the wood escape of the Thousand Hand clan of the Fire Country, the ice escape of the Water Wuyue clan, the melt escape of the Shinomi clan of the Shinomi clan, the boiling escape of the Shinomi clan of the Thunder Country, the Lan escape of the Night Moon clan of the Wind Country, the magnetic escape of the Wind Demon clan of the Red Demon clan, and the explosion of the Dida clan of the Earth Country

Escape. According to the world's statistics on the "compound" blood transit boundary law, each chakra attribute can be combined with the other four. Among them, Wood escape is the combination of water and earth, melt escape is the combination of fire and earth, ice escape is the combination of wind and water, boiling escape is the combination of fire and water, Lan escape is the combination of water and thunder, magnetic escape is the combination of wind and earth, burning escape is the combination of wind and fire, and explosion escape is the combination of thunder and earth. However, this is not all "compound" blood transit boundary. The attributes of each chakra can be combined with the other four. According to this theory, the number of "compound" blood transit boundary should be ten. Therefore, the ninja world has not yet opened the blood transit boundary of wind and thunder, and the blood transit boundary of fire and thunder.

Why is this?

There are two reasons for this: First, after Kaguya Otsutsuki came to Earth, he practiced for four thousand years. At that time, when she first came here, she could already get rid of gravity like the three generations of earth shadows. Therefore, there was almost no place that Kaguya could not reach. Kaguya understood that the power of wind, thunder, water, fire and earth was a skill created by the Otsutsuki clan to imitate natural phenomena. By ignoring gravity and omnipotent power, Kaguya left her own footprints in every corner of the world. I believe there is nothing, there is a better teacher than this world.

So, Kaguya has summarized the truth of all things in the world in the past four thousand years of practice. With the power of the fruit of the divine tree, she turned theory into practice and developed the power of bloodstains. However, as Kaguya was defeated by Yui and Yumura, Otsutsuki Hashi believes that the meaning of chakra is to connect the bonds between people, and to reproduce the miracle of the spiritual communication between people in ancient times, rather than power. Therefore, he destroyed all the practice methods written by Kaguya about blood limits, bloodstains elimination, bloodstains collapse and bloodstains. That's right! Destroyed!

If the world knew that the Six Path Immortals had done such a thing, she would probably smash the Unsuccessful Monument in minutes. I'm going, this is too much of a loser! It's probably her only thought. However, the information about Kaguya on the stone tablet has been modified by Hei Jue. In addition, the world is the Three Egoji Sharingan, so she still can't see the information that the Reincarnation Ange can only see.

First, the Six Paths of Immortals have cut off their inheritance, and second, it is limited by research conditions.

The soil attribute of chakra imitates the earth under our feet, the fire attribute imitates the flame, the water attribute imitates the river, the wind attribute imitates the strong wind, and the thunder attribute imitates the thunder and lightning in the sky. Compared with the other four things, thunder and lightning are in the sky. When ninjas have not mastered the means of flying, their power is difficult for ninjas to study. Among them, the explosion escape and the rami escape related to the thunder attribute were also the exploration of the blood limit when the ancestors saw thunder and lightning shattering rocks, and lightning killing creatures in the water.

Now, the blood-relay limit that the world wants to open is exactly the combination of thunder and fire attributes. It can be said that this is very difficult. After all, what she is going to take now is the path that her predecessors have failed. Doesn’t the world know the difficulty of combining these two attributes with blood-relay limits? Of course, she knows, but among the five attributes of wind, thunder, water, fire, earth, water and earth, water and earth are not mentioned for the time being, because the world’s chakra attributes are wind, fire, and thunder. Among the three attributes of wind, fire, and thunder, the world is the most proficient in mastering the two attributes of thunder and fire. Therefore, although the difficulty of opening the scorching escape is low, it requires the world to invest a lot of time in the wind attributes. Now the world lacks time. She wants to become stronger and stronger, so that she can protect everything she wants to protect. Then, it is natural to choose the blood-relay limits of thunder and fire.

Because there is no previous record of the form and nature of this chakra in the Uchiha clan, the world knows nothing about the blood transcendence boundary of the combination of thunder and fire. Therefore, her current state is to cross the river by feeling the stones and take one step at a time.
