Yuzo looked at the entire book of seals carefully, and he was dazzled by all kinds of things in it. Not only are there all kinds of forbidden techniques that I saw when I watched anime, but there are also some unheard of or even incomprehensible terms.

For example, there is a thing called Spiritual Pollution Technique.,The description effect is to pollute the enemy's spirit and defeat the enemy.,Yuzang is incomprehensible.,Its precautions also say that this technique.,The risk.,That is, it's extremely easy to suffer backlash...

Polluting the spirit, does it mean spiritual energy? Let the enemy be infected with psychosis? Schizophrenia or depression? Should this be classified as an illusion type?

In short, it is impossible for Amazo to choose this.

In addition, there is a forbidden technique called the self-detonation technique.,Just look at the name to know what it will be.,It's just that Yuzo doesn't quite understand that self-detonation has appeared in the Hokage.,Is it a secret art? Detonating one's own chakra is actually not a hidden skill, and it has been taught in ninja schools...

The self-detonation technique of an ordinary ninja is at most like the power of the detonation charm, which cannot be said to be small, but it is definitely not big. A powerful self-detonation technique like Deidara is extremely rare, and I'm afraid it can be compared to the self-detonation ability of the tailed beast.

I don't know what's different about this self-detonation technique on the Book of Seals.

Anyway, Yuzang won't learn this kind of thing, so it's better to learn the Eight Gate Dunjia.

Next, there are some forbidden techniques such as blood escape techniques, shadow clone self-explosion techniques, and some forbidden techniques that can be known by looking at the name, and there are many in the Book of Seals.

Eventually, Amazo made a list of several goals to be selected.

In addition to the Flying Thunder God Technique and the Dark Walking Technique, Yuzang found a few techniques that looked good for consideration and screening.

The first is the atomization technique, which is a technique used by Kato Tsuna, which involves the essence of the soul and spiritual energy, similar to the effect of the soul out of the body, and the soul body is not affected by ordinary physical attacks, and the lethality is huge. Its disadvantage is very obvious, that is, after using it, it needs teammates to take care of the unconscious body like Ino's heart turn, and Yuzo will not have such teammates to help him in the next period of time. Therefore, the reason why he chose this technique was not to learn from him, but to understand the principle of this technique and try to develop a line escape for the soul.

The second is the famous Bamen Dunjia, the reputation of this technique comes from the achievements of the two fathers and sons, Maite Dai and Maitkai. One opened the door of death and overturned the seven knives, and the other almost proposed the finale with one kick. However, the shortcomings of this technique are also particularly obvious.,Needless to say.,Death Gate is a technique that sacrifices life.,After opening, Naruto, who didn't get the power of Yang Dun in the late stage, saved his life was a dead end.。 Of course, regardless of the problem of the death door, the first seven doors are very good, and the improvement is also very huge for the rain hiding who specializes in physical arts, so it is also included in the alternatives.

And the third and final technique is a forbidden technique that has not seen a name in the original book, Chakra Burning Technique.

This so-called chakra burning technique is very simple, and based on the name, you can understand what it does and make the chakra burn. Unlike the self-detonation technique mentioned above, which cannot be interrupted after the start and then burns all the chakras in an instant, it is a controllable and orderly chakra burning.

As for why this technique is included, we will talk about it later.

In fact, he had an idea, that is, to find Tsunade to ask for the cultivation method of the Wet Bone Forest Immortal Technique. According to logical thinking, it is possible that the immortal art of the original Hokage came from the mountain-like slug in the Wet Bone Forest, anyway, Tsunade in the original book did not show the immortal arts, probably because he did not learn the immortal arts of the Wet Bone Forest.

But after careful consideration, he gave up this idea, he was not familiar with Tsunade, and it was impossible to give him this kind of thing, even if he used the reason that Konoha promised to reward himself for forbidden arts, Tsunade had a greater chance of giving him a punch. Not to mention, the immortal art of the Wet Bone Forest was not written on the Book of Seals, although because the immortal cultivation was likely to turn into stone, it could be regarded as a dangerous forbidden art.

And these three options need to be considered.

First of all, the Eight Gates Dunjia was excluded by Yuzang, not because this technique was difficult to practice, nor because the death door was opened, but because of the reason why the death door was opened, the most important thing was the cultivation speed of this technique. Not to mention that Emperor Kai doesn't know how long it takes to practice to open the eight doors, how many doors can Xiao Li open when he learns this technique and faces the six spots?

Yuzang's memory is a little vague, but Xiao Li definitely didn't open the seven doors, and the six doors may not have any. This kind of cultivation speed can be said to be relatively slow, and Yuzang doesn't think that his physical talent is better than Xiao Li's, so he can only choose to give up.

At present, the top priority is to improve the strength.

And then what was ruled out was the atomization.,The shortcomings of this technique have been mentioned before.,And compared to the thread escape for the soul that may not be able to be developed by taking this technique into the hands.,Yuzang is more inclined to the third technique.。

Chakra Incendiary!

The controlled, orderly chakra burning described by this technique reminds Yuzo of one thing, and that is fuel! Fuel for machinery!

Rain has used its own wires to try to form some machinery, such as the small motors mentioned earlier. But the disadvantage of these composed machines is that they can only rely on Yuzang's control of the line to provide power, and how much power can he generate from his operation of the line? Obviously not strong.

And now this chakra burning technique has become a possible way to provide power. Yuzo only needs to combine the lines of the engine structure in his memory, and then burn it with chakra as fuel to create a real machine with powerful power, instead of the toy motor before.

He had been a mechanical fan in his previous life, and he also knew some of the principles of gunpowder weapons. Although he is not a professional talent, he just relies on his interest to do some understanding and research, but he can also understand a little. In the era of the information explosion, it is indeed very convenient to learn such knowledge, and if you keep trying according to the knowledge in your memory, you will definitely be able to imitate what four-cylinder engine and AK47 or something...

So he made up his mind, this is the thing!

With this forbidden technique, even if it is not used to make things like engines, it can be used to make a large killing weapon such as a thermal weapon and a firearm, and the bullet line fired by hand is far less powerful than the real bullet!

Naturally, the engine is not used to make useless things like cars, and although it must be fun to drive a car made of wires, it is more important to build some robots like Gundam.

Chakra is much more powerful than gasoline or something, and the energy produced after combustion is very different.

Imagine that one day when he makes a robot composed of lines that is several meters tall, fierce, powerful and capable of flying, and uses modern thermal weapons to destroy the enemy, the third-generation Wind Shadow puppet of the Scorpion is weak!

Perhaps the biggest difficulty is whether the current wire can have the ability to withstand high temperature and high pressure.

Even if it can't be for the time being, one day when the chakra is strong enough, this idea can be realized.
