After combining his current physical examination data with the previous data of Xiang Phosphorus, Shinji pressed the urge to transplant the first generation of cells immediately.

Impacting the eye of reincarnation is such a thing, and if you want to hurry, you can't reach it!

And as long as all the links are properly prepared, the goal that can be achieved steadily, he really does not need to be greedy for merit.

Putting away his thoughts about the operation, he shifted his energy to sorting out the 'legacy' of the Demon Slayer World.

Through careful classification and combing, Shinji confirmed that he had collected a total of 30 breathing methods, including the 'Breath of the Sun', the origin breathing method of the breathing method, and various other branch breathing methods created by later generations.

In addition to the breathing method, there are a total of 742 volumes of cultivation techniques, experiences, and experiences related to the breathing method.

Among them, nine volumes involve the high-level realm of breathing methods such as 'markings' and 'permeable world', and two of the nine volumes are even written by Ryuhei Sanyashiki, which almost summarizes the understanding, research and outlook of the predecessors of the breathing method, and marks their own views, which is a very valuable reference material.

Not to mention that he has eaten all these materials thoroughly, but after a rough combing, Shinji himself has benefited a lot, and combined with the medical ninjutsu system he has mastered, he has a clearer route for optimizing the direction of breathing methods.

"The swordsman's development of the breathing method has not reached the extreme." After a pause, he continued to say secretly: "It's not their fault, it's that their bodies are not enough to support them to continue to develop the breathing method, after all, just turning on the 'markings' is enough to cause the genius among them to die young, and I am different"

Shinji is well aware of his strengths.

Chakra makes the ninja's vitality far surpass that of the swordsman, and the existence of medical ninjutsu gives the ninja the opportunity to challenge the limits of the human body.

Therefore, in his opinion, at least before the 'Six Dao Levels', optimizing the breathing method can bring him a great increase in combat power, which can help him maximize the use of his body's strength.

As for the 'Six Dao Levels', the body at that time had already begun to be chakraized, or the energy was digitized, such as the 'Eight Doors Dunjia' and the 'Breathing Method', which were based on the secret techniques of human flesh and blood organs, and their usefulness was greatly reduced.

It's like the big barrel wood Kaguya, she doesn't need to cultivate this kind of physical secret art, and the 'Eighty Divine Air Strike' she casts is stronger than the final mystical 'Night Kai' launched by Maitkai who opened the 'Door of Death'.

This is not to say that Kaguya's physical skills are better than Kai's, but as a 'blood following snare', Otsuki Kaguya no longer needs physical secret techniques to improve her utilization of her body, because her body has long been chakraized and has been detached from the level of flesh and blood.

This makes the clumsiness of physical fighting skills not prevent her from giving full play to her strength at will.

After sorting out the information related to the breathing method, Shinji began to sort out the information related to the 'ghost'.

This part is actually more appealing to Shinji than the 'breathing method', because immortality is an irresistible temptation for any living being.

However, after carefully sorting out the information related to 'ghosts', Shinji was faintly disappointed.

The potential of the ghost is actually not as great as Shinji imagined, and the strength of the ghost has increased, and to some extent, it is completely controlled by the ghost king.

Other words.

Once you become a ghost, you are almost equivalent to a slave of the ghost king.

At that time, Ryuhei was the first to capture the Onimai Tsuji, and after using a certain method to divide the power of the oni king of the oni dance, Tsujimu was a ghost by absorbing the power of the oni king, which allowed him to get rid of the control of the oni king.

If he became a ghost in some other way, then even if he was a 'lantern bearer', he would still be limited by the ghost king.

Ordinary ghosts, although they have a long life, but the improvement of their strength is limited to the ghost king, and the ghost king can almost kill him.

And the improvement of the Ghost King's strength is relatively unlimited.

But judging from Ryuhei's notes, after reaching a certain critical point, the strength of the Ghost King will actually come to a standstill. No matter how much you devour living beings and drink flesh and blood, the growth of strength will become extremely slow.

Ryuhei himself is a prime example.

He has slaughtered many civilizations, and the number of creatures he has killed is difficult to verify, but even so, his strength has not broken through the limit of the foreign object of 'ghost', no matter how brutally he plundered, he is still trapped by the power of flesh and blood, and his efforts are only very slow to enhance the use of flesh and blood.

Therefore, the Sanyashiki Ryuhei itself is the most intuitive example.

Even if you give up the dignity of the human body, the structure of the human body, and even the form, the ultimate limit of the power of the ghost king, it is just Ryuhei Shiki!

Compared with.

After the 'Six Dao Levels', he chakraized himself, and used his soul and body to back up his body with chakra, impacting a higher-level life form, which was obviously a whole grade higher than the power of the ghost king.

Therefore, in the ninja world where there is chakra, it is obviously a fool's behavior to give up the achievement of the 'Six Realms', or the stronger 'Blood Relay Snar', and instead destroy one's body and become a foreign object like a 'ghost'.

And according to Ryuhei Sanyashiki's research, oni cannot achieve immortality in the true sense.

A low-level ghost will slowly lose itself in a long life, lose its will as a human being, and eventually become a bloodthirsty beast.

For relatively high-level ghosts, the loss of self will be slower, but it will still not be contained.

Even the Ghost King himself has this problem.

Ryuhei Sanyashiki mentioned in a notebook that if it weren't for the 'lamp' reminding him at all times, he wouldn't even be aware that part of his will as a 'human' was being consumed little by little.

He analyzed that this is because of the alienation of the body, which has caused his senses to change, and his thinking patterns, pain perceptions, physiological reactions, etc. have also begun to be different from ordinary people, which makes him become a ghost not only physically, but also psychologically.

And the bloodthirsty instinct will destroy his original morals and values, slowly affect him, and eventually alienate him into a completely different person from his original self.

"Huh"

Looking at the analysis in Ryuhei's notebook, Shinji smiled.

As a Shinji medical ninja, it can naturally be seen that Ryuhei's analysis is not comprehensive, and the most critical factor in slowly losing one's will when you become a ghost is because the power of the demon's flesh and blood also exists in its own consciousness, and the bloodthirsty instinct is its external manifestation.

The stronger the power of flesh and blood, the stronger this will will be rooted in flesh and blood.

Under the influence of one another, the part of the will that is a human being will naturally be slowly suppressed, and finally completely consumed, and the whole person will be reduced to a monster driven by flesh and blood instinct
