(ps: I found out that I'm quite evil, what chakra trees I talked about before, in fact, I casually talked nonsense!) As a result, looking back at the manga, in chapter 315, Kakashi taught Naruto to carry out chakra qualitative transformation, there really is such a tree! It is really used to make chakra test paper! Is this a crooked attack or an unintentional willow insertion...... ）

"Bloodstained Boundaries...... A new retreat created by the simultaneous change of the nature of two or more attribute chakras......"

In the forest of the Tea Country, on the crown of one of the tallest and thickest trees, Kanaten stood leisurely with his eyes closed, feeling the breeze blowing, his hair fluttering, and the hem of his clothes swaying, like a god standing in the clouds, as if he was about to turn into a fairy in the next moment. Pen ~ fun ~ pavilion www.biquge.info

"Chakra itself can't affect matter, but after it is changed, it can interfere with reality...... Kannaten whispered to himself, "If the essence of ninjutsu is a phenomenon of chakra interfering with reality, then what is the essence of chakra?"

For beginners, chakra has no form or nature, just a formless and insubstantial "qi", and at this stage, ninjas can only communicate with the outside world through ninjutsu. However, when the ninja changes the form or nature of the chakra, they can directly use the chakra to interfere with reality, such as condensing the chakra into a ball-shaped spiral pill to directly attack the human body, or using the wind to cut the leaves, and using the fire to make the paper burn, etc.

To take an inappropriate example, the change of form is like compressing the "qi" of chakra into a gas bomb, and the change of nature is to turn the "qi" into "fog", "water", and "ice", and the deeper the change in form or nature, its intensity will also increase, which is the essence of most ninjutsu.

The bloodstain boundary is to fuse the chakra of two or more attributes after the change of nature to form a special chakra, and to open up a new retreat, because the chakra is a collection of physical and mental energy, so the difficulty of fusing the bloodstain boundary is like a writer who is taking an exam, thinking about the solution of the problem on the one hand, but thinking about the content of the next creation on the other hand, and answering the question and creating at the same time, it is obvious that this kind of difficulty of single-mindedness and dual-use is unimaginable for ordinary people。 (Yes, the author, who just finished the exam, told everyone that it would be confusing just to get distracted, let alone write a novel during the exam...... ）

In fact, the bloodstain boundary is not a secret, many people in the ninja world know the principle, and there are many people who try to parse the mystery, but if you can't achieve "one heart and two uses" and "one body and two uses", then it will be in vain after all.

In Kannaten's view, the Bloodline Limit is a bit like a two-handed fight in martial arts, but it is much more difficult, because humans may be able to control their bodies through exercise, but it is difficult to control their minds.

At the beginning, Jiraiya taught Naruto the shape change of the spiral pill, and the first step of refining chakra is to let it condense the spirit, in a mysterious sentence, that is, to achieve "non-thinking, non-thinking", neither thinking about things, nor thinking about things, of course, we can also explain it with a simple sentence, that is, to empty the brain, between being in a daze and not being in a daze, and turning the matter of refining chakra into an instinct, just like eating and drinking.

It is impossible for human beings to think about two things at the same time in their minds, there must always be a sequence, so in order to develop the bloodstain boundary, it is necessary to "instinctively" change the chakra nature of one of the attributes! The other is actively controlled by human beings to complete, and then the two are integrated to be considered complete.

When humans eat and drink, they don't need to think about which muscle of the arm needs to be mobilized, and they don't need to direct how the electrical signals of the cranial nerves are transmitted to the arm, all of this is instinct, so human beings think about the problem while eating and drinking, and in the same way, only by turning the change in the nature of chakra into an instinct, can they complete the fusion of two or more attribute chakras at the same time, and create a bloodstained ninjutsu that goes beyond the scope of ordinary retreat techniques!

Anyway, Kannaten doesn't believe that someone can actively control the two chakras in his body to make qualitative changes at the same time, just like thinking about "left" and "right" at the same time when he takes a step, he will definitely fall.

Kannaiten spread out his hand, staring fixedly at the lines of his palm, and an inexplicable look appeared on his face.

A little surprised, a little ridiculous, a little unbelievable.

"In this way, Takamagahara is equivalent to an auxiliary organ, which can instinctively transform the deformation and qualitative transformation of chakra, so I only need to complete a qualitative transformation of chakra, and then with the help of Takamagahara's words, I can directly develop bloodstains?"

The attributes of Kannatian are water and earth, and there is more than one bloodstain boundary born after the fusion of these two attributes, but the most classic and exciting is definitely the unique bloodstain Mu Escape between the Thousand Hands Pillar!

Now that he thinks that he may develop Mu Dun, Kannaiten is really a little excited......

"Then, the secret of the bloodstain boundary that I once speculated should lie in this 'chakra nature change instinctual', through the mysterious power of inheritance in the bloodline, so that the bloodstain awakened person can control the nature change of multiple chakras without a lot of practice, it is like opening a hang......"

"With my knowledge, I can't explain the essence of chakra with the theory of ninjas, so I'll try to explain chakra with the scientific view of my previous life!"

Kannaten plucked a leaf with his hand, and his fingernails cut through the surface of the leaf, outlining a spherical shape on it, which is a model diagram of the molecule.

"Suppose that the chakra is made up of a particle called the 'chakra molecule', which is the smallest unit in the chakra that can exist independently and maintain the chakra properties, and is composed of the more tiny 'chakra atom' that has no attributes and no substance. The structure of the atom determines the properties of the molecule, which in turn determines the properties of the chakra. Compressing or stretching the spacing of this chakra molecule can lead to structural changes between molecules, thus affecting the morphology of the chakra, which is the so-called 'deformation', and different numbers of the same molecule, through different structural arrangements, can be combined into different states of chakra, just like two oxygen molecules make up oxygen and three oxygen molecules make up ozone, which is called 'qualitative change'......

"The chakra nature of human beings depends on which attributes of the chakra molecule in the body are the majority, just like the essential elements and trace elements of the human body, so in fact, everyone can use the five nature of the retreat, but his chakra attribute determines which one he is better at. ”

Smack! Kannaten clenched his fist suddenly, and then slowly opened it, and a small chakra ball condensed into the palm of his hand.

In other words, everyone can carry out five nature chakra changes, but the difficulty is different because of their own attributes, a ninja may only have one attribute of chakra when he is a teenager, but when he becomes a ninja, he can develop two or more. ”

In the original book, Kakashi's original words were: After reaching the upper ninja level, there will be more than two changes in general. This shows that the change in the nature of chakra is not absolute, but can be developed through cultivation, and even with the help of external objects, such as the reincarnation eye that can directly possess the changes in the nature of the five attributes.

"According to my theory, the deformation of the chakra is the spacing of the 'chakra molecule', causing it to expand, contract and even make more complex changes......"

The chakra ball in Kannaten's hand was first squeezed inward, and the red chakra was obviously darker, and then slowly expanded, and stretched little by little, forming an oval shape.

The chakra ball began to change in Kanaten's control, round, oval, cylindrical, flat, triangular, etc., and finally Kanaten's finger flicked, and the chakra ball flew up, stretched in mid-air, and changed towards the image of the dragon.

First the long, curved body, then the two antlers on the top of the head, and then, the eagle talons, bull ears, tiger paws and other limbs manifested one by one, but when Kannaten was ready to go one step further and sketch the scales on the body, it failed.

"I have the Tailed Beast Chakra, and the concentration of Chakra is much higher than that of ordinary people, so for me, the cultivation of Chakra Deformation is very simple, it is simply the difference between controlling gas and controlling solids! Kannaten sat cross-legged on the canopy, holding his chin and thinking silently, "And if the nature changes, water and soil only need to choose one, compared to the water attribute is better at changing the form, so I should choose soil......

The change in the nature of the soil attribute is to change the hardness, composition, mass, gravity, etc. of the object, and the phenomenon that appears on the chakra test paper is to make the paper crush, and the same is true during training, if you can make the object crush without the effect of ninjutsu, it means that the nature of the soil attribute changes are introduced.

"Fire plus wind is scorching, fire and water are boiling, fire and earth are melting, wind and earth are magnetic, wind and water are ice, thunder and earth are explosion, thunder and water are lan, earth and water are wood, fire, wind, and earth are combined into dust......" Shen Natian frowned, feeling a big headache, "In addition, the same two attributes, the degree of qualitative change of each is different, and the ratio of fusion is different, and they will fuse different escapes, such as the same water and earth, which can form wood escape, can also form dissolution, and can also form crystal escape." It's complicated, it's too complicated!"

Chakra has five basic attributes, and all the bloodstain boundaries in the world are completed on this basis, theoretically speaking, every person has five attributes of chakra in their body, as long as they practice, they can complete the changes of the five attributes of chakra, and then fuse with each other to get all the blood stains in the ninja world!

But this is only a theory that exists on paper, the five attributes of chakra can be fused in pairs, three or three, or even four or five, plus the degree of qualitative change and the size of the fusion ratio, it is impossible for a person to study it in a lifetime.

Thinking of this, Kannaten suddenly smiled.

"So, can Takamagahara still be used like this......

Ordinary ninjas, even if they get the corpse of the bloodstained person, it is difficult to crack the secret of the bloodstain, but Kannatian is different, he has a plug-in like Takamagahara, which can perfectly analyze the specific composition of the bloodstain, and only needs to complete the corresponding nature changes, he can master the ninjutsu of different bloodstain boundaries at the same time. For example, now that he has the bloodstains of the bones and veins, if he transplants other bloodstains, it is likely that there will be some kind of conflict, whether the bloodstain boundaries of the bloodline inheritance can coexist, no one knows, but one thing is for sure, you can't have two chakra eyes and white eyes at the same time. And Kannaten can avoid this, he can analyze the bloodstains through Takamagahara, and without transplanting the bloodstains, he can directly cast the bloodstain ninjutsu, just like the original Six Dao Immortals!

The Six Dao Immortals inherited the power of the Otsuki Kaguya, and were able to use all ninjutsu without sealing, note that this everything includes all the blood stains, such as the magnetic escape that changes the magnetic force, the boiling and dissolving escape that makes strong acid, and the Shinra Heavenly Expedition that changes the repulsion force, etc., all of this has no secret to the Six Dao Immortals, just the product of the pure chakra nature change.

On the one hand, by drawing a lottery to improve his ninjutsu reserves, and on the other hand, by analyzing the blood stains to decipher the blood stain ninjutsu, Kannatian's vision for the future is already very clear, and he wants to move towards the existence of the Six Dao Immortals!

As for the principle of bloodstained ninjutsu and the nature of bloodstained boundaries, these don't matter! Master more and stronger ninjutsu and gain more powerful power, this is the goal of Kannatian!

Placing the blade on his knee, Kannaten condensed his mind and condensed a little insignificant chakra on the blade, fantasizing about crushing it in his mind.

Under Kanaten's gaze, the leaves rolled up little by little, and then the surface of the leaves became charred and blackened, and then they naturally burned.

The small flame couldn't touch Kanaten's body or clothes at all, and it was extinguished by an electric current, because during this time, he kept in the state of starting the thunder armor all the time to sharpen his body, so to speak, even if Kannatian sat here and didn't move, he didn't control Chakra at all, and this layer of thunder and lightning on his body was enough for him to have a defense that could resist C-level ninjutsu.

"Hmm...... Is the concentration of chakra in the six tails too high?"

With one breath, the ashes on the knees slowly dispersed and drifted to the earth in the breeze.
