So in the final analysis, the power level of the Demon Slayer World is too low, and the appearance of a foreign object like 'ghost' is already the embodiment of the strongest power in the Demon Slayer World, so no matter how hard Ryuhei Sanyashiki tries, he can't break through the power level of the Demon Slayer World against the sky.

In other words, Ryuhei Sanyashiki is already making a difficult breakthrough.

It's just that if you want to completely break through the shackles of the world's power level, it takes great effort and opportunity, and you have done all the bad things of Ryuhei in Sanyashiki, suffered retribution, and was targeted by the fearful overlord, so naturally there is no chance to continue to try to break through.

Da da da.

Shinji's fingertips tapped lightly on the desk, and his thoughts gradually diverged.

After sorting out the materials related to the 'breathing method' and 'ghosts', Shinji discovered that the essence of the two systems representing good and evil in the Demon Slayer World is a kind of development of the body!

The difference is that the 'breathing method' respects the structure of the body itself, and taps into the power hidden deep in the human body within the original framework of the human body.

The 'ghosts', on the other hand, completely abandon the original structure of the human body, abandon the balance of various organs performing their respective duties, and use flesh and blood as the foundation to strengthen themselves by plundering the flesh and blood of other lives.

The former is conservative and more skillful. The latter is radical and has no taboos.

In terms of the degree of development, the development of the 'breathing method' by generations of ghost slayer swordsmen is obviously far better than that of ghosts who need to fight against bloodthirsty instincts every day.

But the overall strength of the latter is undoubtedly better than the former.

From Shinji's point of view, this is because the 'breathing method' can only mobilize the power of the human body at the level of organs, while the 'oni' can mobilize the power of the human body at the level of cells.

All kinds of 'blood ghost techniques' are actually qualitative changes caused by the combination of cell-level power and spiritual power after reaching a certain resonance.

"'Ghosts' also have merits, and in the application of human cells at the cellular level, they are obviously stronger than 'breathing methods'."

Shinji's gaze slowly deepened.

In his opinion, the 'ghost' is too aggressive and rough in its development of the body.

This makes the 'ghost' become an inhuman being, and although it has gained great power, it has also been rooted in heavy restraints and embarked on a bloodthirsty road of no return.

If we can eliminate the negative effects of 'ghosts', such as bloodthirsty instincts, inability to shine sunlight, and so on, and only use their skills to extract the power of cells, then the power of 'ghosts' is not useless.

Shinji even came up with the idea of combining 'breathing' and 'oni' into one.

One can tap the power at the level of human organs, and the other can mobilize the power at the level of human cells, and when the two are combined, they can definitely produce the effect that one plus one is greater than two.

This is not a whim of Shinji, in fact, such as the oni Tanjiro of 'The Upper String of the One', the Black Death Mou of the 'Upper String', etc., all have the flesh and blood power of the 'breathing method' and the 'ghost', and they all easily become the 'Upper String Oni'.

Even a swordsman who is not very outstanding in the ghost killing team like Miaoyue, after becoming a ghost, has successfully entered the list of 'upper strings'.

In Shinji's view, once he became a ghost, the structure of the human body was severely damaged, and the power of the 'breathing method' was actually weakened.

Even so, the fusion of the two systems can greatly improve the strength, it can be seen that if the two systems can be perfectly integrated, the final effect must be worth looking forward to!

Da da da.

The tapping of his fingertips grew faster and faster, implying Shinji's pulsating thoughts.

"There's a lot to be done!"

He whispered.

In terms of the strength of the promotion to the 'Six Dao Ranks', the strength of the ninja is still reflected in the body and chakra.

Transplanting the first generation of cells is to improve one's own physique by obtaining the ultimate yang retreat chakra of the large barrel wood asura contained in the first generation of cells, which is the improvement of chakra!

The integration of the two systems of 'breathing' and 'ghost' is the development of the body and the improvement of the utilization rate of organs and cells.

The two are not in conflict.

And because chakra is the product of the fusion of physical power and spiritual power, if the physical power becomes stronger, it can also greatly improve the quantity and quality of chakra.

The two not only do not conflict, but complement each other!

Shinji even felt that if his physical strength was strong enough, it would be a big boost for the future impact of the 'Six Dao Level'! You must know that forcibly becoming a ten-tailed human pillar force is a very painful thing, and people like Obito almost fainted in pain, so without a strong physique as support, even if the ten tails are in front of you, it is a very risky thing to become a ten-tailed human pillar force.

Thoughts flickered frequently, and the vague thoughts in Shinji's mind gradually became concrete.

He took out his notebook and began his own ideas.

The whole process is divided into three steps.

The first step is to optimize the 'breathing'.

With the strength of the ninja's body, there is still a lot of room for optimization of the 'breathing method', and the types of 'breathing method' are too complex, so Shinji can completely take the strengths of all the families and use this optimization to create the strongest 'breathing method'.

The second step is to transform the 'ghost'.

The disadvantages of 'ghosts' are too great, and even if the vitality of some 'ghosts' is sacrificed, Shinji must completely eliminate those drawbacks.

At least Shinji must ensure the structure of the human body and the balance of various organs in the body, and must not sacrifice his roots and become a slave of flesh and blood like a ghost!

The third step is to combine the flesh and blood power of the 'breathing' and the 'ghost'.

If the first two steps go well, this third step is actually not too difficult, after all, Shinji has not only practiced the 'breathing method', but also learned medical ninjutsu, and knows all the organs and various physiological structures in the human body well, and many problems that are difficult for swordsmen or ghosts to overcome are not a problem in his eyes.

Shinji already had an idea for optimizing the 'breathing method', or rather, it was inspired by Ryuhei's notes at the delivery house.

Ryuhei Sanyashiki had actually considered optimizing the 'breathing method', because in his opinion, the wide variety of breathing methods would only distract the swordsmen. Only when everyone is dedicated to one breathing method can we continue to improve and perfect this breathing method.

But throughout his life, he was not able to create a perfect 'breathing method'.

This is not only the lack of vision and realm of Ryuhei in the delivery house, but also the existence of many objective factors, but here in Shinji, these problems do not exist.

The existence of Hitomi allows Shinji to easily see the flow of air inhaled from the mouth and nose, the changes in the human body, the flow of blood in the blood vessels, the force of muscle contraction, and so on.

And the existence of medical ninjutsu can allow him to use chakra to easily strengthen a certain organ in his body, a certain airway, and a certain blood vessel in his body.

None of this is something that a swordsman can do

The second is even more served! Ask for a recommended ticket, a monthly pass! Hands-on, please!
