Bloodline Inheritance Limit is a technique that can only be inherited by blood relations through genes under normal circumstances. Usually, except for those of the same bloodline, who can inherit it, no one else can learn it, and even if you use the Sharingan, you can't copy it. And here, the blood inheritance limit that the world wants to cultivate is a retreat technique.

There is a risk in cultivating the blood inheritance limit, which is recorded in detail from the Uchiha clan's magic room, what the so-called risk is, that is, blood inheritance disease. In other words, it's a genetic breakdown, a terminal illness of a ninja. In the research of the Uchiha clan, the statement that chakra equals soul equals genes is officially established. And combining the changes of the two chakra attributes into one can give rise to new attributes. And this new attribute of chakra, will cause huge changes in genes. If you can survive this genetic change, then congratulations! You will have your own bloodline limit, and this bloodline limit can be passed down through the bloodline. If you didn't make it, then sorry! You will be doomed to die in the disease of blood.

The foundation of the Escape Technique Blood Inheritance Limit is the five attributes of wind, thunder, water, fire, and earth.

The Uchiha clan divides all the current ninja realms into two categories, the first type is called the "Extreme Type", and the second type is called the "Compound Type". Let's talk about the "extreme type" first, because the last bloodline of the White Water Clan was killed by the world, so the Uchiha Clan did not have to worry about the retaliation of the White Water Clan, so they justifiably obtained the body of the White Water Santu, and also got some secrets of Miao Dun from it. The Miao Escape of the White Water Clan, although it only involves a change in the chakra attribute, that is, the water attribute. However, its power goes far beyond the water escape itself. The world exerts this single attribute to the extreme and is far superior to the original attribute of the retreat technique, which is called the "extreme" blood inheritance limit. And her Blue Fire Escape, although its power is much higher than the original Fire Escape, its essence has not changed much, so the world does not classify the Blue Fire Escape into the category of the Blood Inheritance Limit.

Now that the "extreme" blood inheritance limit is finished, let's talk about the "compound" blood inheritance limit!

The "compound" bloodline limit refers to the combination of two chakra attributes, resulting in a new attribute of chakra. If the chakra strength of the five attributes is set to "1", then the chakra strength of the "extreme" bloodline limit is "2-3", and the strength of the "compound" bloodline limit is "4". At present, there are a total of eight types of "compound" blood inheritance limits in the ninja world recorded by the Uchiha clan, namely the wood escape of the Thousand Hands clan of the Fire Country, the Ice Escape of the Water Country Mizuki Clan, the Melt Escape and Boiling Escape of the Terumi Clan, the Lan Escape of the Night Moon Clan of the Land of Thunder, the Magnetic Escape of the Wind Demon Clan, the Burning Escape of the Red Devil Clan, and the Explosion Escape of the Dida Clan of the Earth Country. According to the world's statistics on the law of "compound" bloodline limits, each chakra attribute can be combined with the other four. Among them, Mu Dun is the combination of water and earth, Melt is the combination of fire and earth, Ice Dun is the combination of wind and water, Boiling Dun is the combination of fire and water, Lan Dun is the combination of water and thunder, Magnetic Dun is the combination of wind and earth, Burning Dun is the combination of wind and fire, and Explosion Dun is the combination of thunder and earth. However, this is not the limit of all "compound" bloodlines. Each chakra's stat can be combined with the other four, and according to this theory, the number of "compound" bloodline limits should be ten. Therefore, at present, the ninja world has not yet developed the blood inheritance limit of wind and thunder, fire and thunder.

Why is that?

There are two reasons for this: First, after coming to Earth, Otsuki Kaguya has been practicing for 4,000 years. At that time, when she first came here, she could already escape gravity like the three generations of Tsuchikage. So, in the heavens and the earth, there is almost no place that Kaguya can't reach. Kaguya understands that the power of wind, thunder, water, fire, and earth is a technique created by the Otsuki clan to imitate natural phenomena. With the power to defy gravity and do everything, Kaguya has left its mark in every corner of the world. There must be nothing better than this world! As a result, in these 4,000 years of practice, Kaguya summed up the truth of all things in the world. And with the power of the fruit of the divine tree, she turned theory into practice and developed the power of the bloodstain snare. However, with Kaguya, he was defeated by Hagoromo and Hamura. Otsuki Yuroi believes that the significance of chakra is to connect people with each other, to reproduce the miracle of people's hearts and minds in ancient times, rather than power. Therefore, he destroyed all of Kaguya's cultivation methods on the Blood Inheritance Limit, Blood Inheritance Elimination, Blood Stain Collapse, and Blood Stain Snarring. That's right! Destroyed!

If the world knew that the Six Dao Immortals had done this kind of thing, it was estimated that she would be able to destroy the Zhizhi Monument in a few minutes. I'll go, it's too much of a loser! I guess it's her only voice. However, the information about Kaguya on the stone tablet has been modified by Black Jedi. In addition, the world is the three-hook jade writing wheel eye, so she can't see the information that the reincarnation eye can see.

First, the Six Dao Immortals cut off the inheritance, and second, it was limited by the research conditions.

Chakra's earth attribute mimics the earth beneath our feet, the fire attribute imitates flames, the water attribute imitates rivers, the wind attribute imitates strong winds, and the thunder attribute imitates thunder and lightning in the sky. Compared to the other four things, thunder and lightning inhabit the heavens. Before ninjas had mastered the means of flight, their power was difficult for ninjas to study. Among them, the explosion and Lan escape related to the thunder attribute were also triggered by the ancestors who saw the thunder and lightning shatter the rocks and the thunder and lightning kill the creatures in the water, which triggered the exploration of the blood inheritance limit.

And now, the blood inheritance limit that the world wants to develop happens to be a combination of thunder and fire attributes, which can be said to be very difficult, after all, what she has to take now is the path that her predecessors have failed. Doesn't the world know the difficulty of combining these two attributes to develop the Blood Inheritance Limit? Of course she knew, but among the five attributes of wind, thunder, water, fire, and earth, water and earth were not mentioned for the time being, because the chakra attributes of the world were wind, fire, and thunder. Among the three attributes of wind, fire, and thunder, the world is most proficient in mastering the two attributes of thunder and fire. Therefore, although the difficulty of developing Scorching Escape is low, it requires the world to invest a lot of time in the wind attribute. And now what the world lacks is time, and she wants to become stronger, to become stronger, so that she can protect everything she wants to protect. Then, it is a matter of course to choose the development of the blood inheritance limit of thunder and fire.

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