In fact, crafting a Sarah's golem is the quickest way to master the seal.

But Ryuuji doesn't just want a trustworthy seal key, it also has to be a key that can be passed on freely.

Not by blood, but by election.

Just like the Election Shadow, the person who holds the key must be someone who is approved by everyone in the village.

After all, the dragon vein is the energy source of the organ city, and if it goes wrong, the entire organ city will be paralyzed.

If it is passed down from generation to generation, over time, the village can easily be controlled by a certain family and become their private property, which is not conducive to the future development of Shayin.

On the premise of understanding the principle of sealing, it will not be long before the method can be deduced by reverse analysis with the observation instrument.

Ryuuji set up a dragon vein seal on the observator, and let the observator analyze and deduce it by itself.

And he himself focused his attention on Yamato's arm.

The arm was well preserved, as if it had just been cut off, the blood was still flowing, and the cells were full of life.

He put his arm under the scope to deduce and restore Yamato's body model...... It should be mentioned here that the observatory can set up multiple projects at the same time and work at the same time.

However, doing so would distract the observer's computing power, resulting in a reduction in the analytical deduction of several items, which he would not normally do.

However, it is also possible to make adjustments depending on the situation.

The analysis of the essence of chakra has been going on all along, and the dragon vein seal and the structure of Yamato's body model are deduced...... It's not a lot of work at all, and it can be done quickly, and it won't delay the chakra analysis project for long.

In particular, if you don't study the difference and principle of Yamato's body model from other bodies, it will be done in minutes.

……

Yamato's body model was soon deduced, and Ryuuji directly used a 3D printer to make a living body out.

However, no corresponding soul was made.

This is just to prevent the life vitality of the arm from passing, and the cell necrosis cannot be continued to study and make backup materials, not the wooden ninja.

If you are a ninja, you need to go to Konoha to find a suitable candidate first, and then make the appearance of that person to replace it.

Putting the living body into the preservation jar, Ryuuji continued his research.

He placed his arm under the sphere of the scope and illuminated it, projecting the structure of the body model to see how it differed from other people's bodies.

However, after some observation, no structural differences were noted.

But.

Although there is no difference in the structure of his body, his cells are very vigorous and full of vitality.

And, very domineering.

Ryuuji extracted a little Yamato's cells and fused them with other people's cells, trying to see if this kind of cell could be transplanted, but Yamato's cells instantly engulfed other people's cells.

"Is this the intercolumnar cell?"

Ryuuji fell into deep thought.

This kind of cell is very domineering and murderous, and if it is transplanted to the human body, it will instantly absorb the person's vitality as nutrients, so as to strengthen itself, this phenomenon is like ...... The same as the sacred tree.

"Speaking of which, when I visited the forum in my previous life, I also heard that the Mu Dun between the pillars was not a simple blood inheritance limit at all, but came from the power of the divine tree, and I didn't know if it was true or not. (Really, it says in the formula book)" Ryuuji folded his hands around his chest and bowed his head in deep thought.

This statement is not impossible.

After all, the sacred tree is the Ten Tails, and it is also Kaguya.

It is reasonable that Tsuruma will appear as a descendant of Kaguyahime, and the power of the Sacred Tree is exactly the same as that of the Sacred Tree, both of which are plant attacks and have the effect of suppressing and absorbing chakra.

If Mu Dun's power comes from the Divine Tree, then can I use it as a seed to research a new Divine Tree?

Ryuuji had a whim, and his heart was immediately moved.

If he can make a new Divine Tree, then he can completely bypass the research and directly reach the realm of the forest by devouring the chakra fruit, so as to directly understand and control everything about the chakra.

However, this is just a thought.

He hadn't even studied Mu Dun thoroughly now, let alone used Mu Dun as a seed to grow a divine tree.

No, even if you can do all this, you need to have a strong strength to ensure it.

The scourge of the Divine Tree to the planet is too great, and if the Divine Tree is planted on this planet, the Six Dao Immortals will 100% jump out of the coffin board and dry themselves.

So......

"Let's take our time, and study Mu Dun thoroughly first."

Ryuuji re-extracted a little bit of the inter-column cell, and then a little bit of Naruto's blood, allowing the two to fuse.

This time, instead of absorbing Naruto's cells as nutrients, the intercolumnar cells lived in them as if they were home—that is, they fused together perfectly and became new cells.

In this regard, Ryuuji is not surprised at all.

In the Hokage finale, Naruto took a right hand made of intercolumnar cells, indicating that his body does not reject intercolumnar cells.

After that, Ryuuji fused the cells of ordinary people with the new cells that fused.

The two were repulsed, but there was no engulfment.

"The new cells have become gentle, no longer have the instinct and ability to devour other lifeforms, but they have become stronger and larger in themselves, and if they can use this cell to form the structure of the body, then the vitality of this body will definitely be superb."

Ryuuji groaned slightly, and then used the observation instrument to analyze and deduce the cells, he wanted to know how strong the body was with the combination of this body cell.

The results of the deduction came out quickly.

Possess ten times more physical strength than ordinary people; Ten times more physical recovery than ordinary people; Ten times more than ordinary people's vitality, and ten times more life resilience than ordinary people...... And, as you exercise and the higher the physical intensity, these abilities grow exponentially.

Looking at the data given by the observer, a word popped up in Ryuuji's mind: immortal human body.

In the Hokage, the concept of the immortal human body is not explicitly given, which is the reader's physical name for the people who have super vitality and recovery ability among the descendants of Otsuki, which is used to benchmark the writing wheel eye of the immortal eye.

"It's easy to design a body made of these cells, but you have to think about rejection."

The study of the immortal human body naturally wants to be used on oneself.

However, the research just now has shown that the cells of the immortal human body will be repulsed from the cells of ordinary people, and it is not impossible to directly use the method of soul transfer, but the defect is too great.

It's not your own body, and the rejection of the soul is also great.

Even if you have a body with excellent compatibility, it can only be used for a few years at most, and if you are injured from outside, this time will be further shortened.

"We still have to find a way to fuse immortal cells with ordinary human cells, but before that, we can upgrade Silver's body."
