The four generations took out a very ordinary small book, the dark brown cover did not have any graphics or text, and the traces of long-term use made it look a little old, but it was not broken, because the fourth generation of this person seems to be the kind of person who is very careful not to make this kind of thing tattered.

Took the book, Yuzang said thank you, and opened it for a meeting to read it carefully.

Seeing that Yuzang's motivation to study was not small, the four generations no longer bothered him and said: "I'll go back to the house to rest first, you'd better adjust your state, you can't do without your participation in the battle in the future."

Judging from the appearance, among the several people at this time, Yuzang's strength can be ranked second, Kakashi is too young, but Ding Za and Zhiwei are both worse than him. Although compared to the four generations, Yuzang will probably be the kind that is directly killed in seconds, but his ability to deal with large puppets is still better to use.

"yes, I know." Absentmindedly replied, Yuzang's thoughts were poured into the small book in his hand.

The four generations didn't say much, as for giving that thing to Yuzang so easily, first of all, this book didn't actually have much use for him, and the bigger reason was because he didn't care much. In the eyes of the four generations, since they are Konoha people, if they can really learn to fly the thunder god, it will also be of great benefit to the village. It doesn't seem like a person who will be bad for the village.

Just like the guards around the three and four generations of the Ignorant Fire Genma, they also received guidance from the four generations, but unfortunately they only learned half-baked, and they still need three people to use the Flying Thunder God together, and the speed is no different from a snail crawling.

What is recorded in the book is the process of four generations of practicing the Flying Thunder God, some thoughts in the middle, and so on.

As I said before, the most fundamental principle of Flying Thunder God comes from the spatial movement of spiritism.

If you want to explain it in detail, the first thing is to establish a coordinate. In the second generation of Flying Thor, this coordinate is built entirely on the ninja's own chakra and spiritual energy. For the second-generation Hokage Senju, the physique of Senju allows him to have a powerful chakra, and also a strong enough spiritual energy, so the coordinates can be quickly built within a certain range and applied in actual combat. However, ordinary people do not have this kind of coordinate construction speed and sufficient chakra, which is also the first difficulty that prevents ordinary people from mastering this technique.

And the fourth generation, this has been improved.

By attaching the coordinates of the technique to the entity of kunai, the requirements in actual combat are greatly reduced, and only the coordinates and procedures need to be set on the kunai in advance, and the kunai can be thrown in actual combat to move the coordinates to the corresponding position. Although this will also have certain limitations, it is also much faster and more convenient than the second generation.

Once the coordinates and procedures are complete, the next step is to move.

As a technique that really involves the spatial aspect, the movement of the Flying Thunder God is through the interconnection between itself and the coordinates, and then an enchantment is unfolded to wrap itself, shrinking to a certain extent and then attracted by the coordinates, so as to achieve the purpose of teleportation. As for how small is this shrinkage? Yuzo's guess may be to the extent of the atomic nucleus or something smaller in the microcosm...

The process is extremely fast, from wrapping itself to shrinking and moving, to restoring the disappearance of the enchantment, and the time it takes can be calculated in ten-thousandths or less. In fact, the caster himself has no means to control the process, and no one on this time scale can react, not even the fourth generation of people who have such a shocking fast reaction nerves. What really needs to be reacted to is the environment and the situation after the move is completed.

As for the enchantment that wraps itself, you can refer to the kind of enchantment that the fourth generation stopped the nine-tailed beast jade, which is a further application of the Flying Thunder God developed by the fourth generation.

And mastering the use of this enchantment is also the second difficulty of the Flying Thunder God, a difficulty that no one can cross except for the second and fourth generations. The difficulty lies in the difficulty of control. This kind of enchantment involves a problem of chakra's nature change, and if you want to use ninjutsu to release fire escape, chakra needs to change the nature of the fire attribute. In the same way, in order to use the splay enchantment, you need to change the chakra in a nature.

Let's call it the chakra nature of space-time attributes.

This is the most difficult point, countless people are stuck at this pass and have no way to master the Flying Thunder God, and the same is true for Yuzang, the difficulty of setting coordinates on Kunai is still there, but it's okay. But this chakra nature change, compared to the Yang Dun nature change that Jilai also taught him before, can be said to be a big deal.

In the notes of the four generations, there is a detailed record of this paragraph.

However, Yuzang finally put away the book and began to close his eyes and recuperate. No matter how much Flying Thunder God studied, it was impossible to learn it in the past few days, and the biggest problem at present was to kill Ma De as soon as possible and end the matter on Loulan's side. After that, there will be time to study it slowly.

About three hours later, the four generations woke up and fell asleep, and began to assign tasks to everyone, as well as remind them of the things that need to be paid attention to in the task.

"Kakashi, you work with Dingza and Shiwei to protect the queen and go to the dragon vein, and try to close the dragon vein as soon as possible. The three of you are tasked with keeping her safe, you know? As for me and Yuzang, it is complicated to block An Lushan's attack, as long as you successfully close the dragon vein, this battle will be won by us! The four generations summed it up briefly.

Naturally, Yuzo didn't have much of an opinion, but Kakashi acted like he was acting with the four generations. But after all, this was in the middle of the mission, and he knew that it was not the time, so he didn't say anything.

Since then, the mission to save Loulan has entered the final stage.

At this time, Loulan has become a very deserted place, and all the puppets who were still wandering around gathered in the center of Loulan, where the center of the dragon vein is located.

When it comes to the form of the dragon vein, no one has really confirmed what it is.

In the center of Loulan, dozens of meters underground, the dragon vein suddenly rose like an underground river or something, and then protruded this section and then sank deep into the ground. It looked like it had a faint blue glow, as if it were really a river, but it certainly wasn't.

In Loulan, the dragon vein is sacred.

Queen Loulan protects the city from natural disasters in the desert by controlling the dragon veins and protecting the people of the country. It's a pity that the queen of the previous generation listened to the rumors, the dragon vein was used by careerists, and the people here were also in dire straits.

"Meat Bullet Chariot!" Seeing the large puppets blocking the road, Ding Za got on without saying a word, and suddenly countless stump fragments flew into the air, and Zhiwei and Kakashi quickly rushed forward with Sara.

On the other hand, the four generations and the rain began to clean up these things.

Compared to the four generations who used extremely fast speed to flicker everywhere and use the wind attribute chakra blade to cut off a puppet, the line of rain hiding swept a large area, and the efficiency was very fast. The next four generations even stopped to rest and watched Yuzo get busy.
