"Teacher. ”

Seeing Zhao Yu coming, Cao Ang and the others saluted.

Zhao Yu smiled and said, "Seeing that you are asking energetically, it is probably not the right time for me to come." ”

The teacher was serious. ”

Zhao Yu was very strict when teaching them, but outside of class, he was very close to his disciples, and from time to time he made some innocuous jokes, and the disciples were no longer surprised.

Zhao Ji saw that her husband was coming, and gave him a blank look.

After chatting with Cao Ang for a while, the class was restarted, and the morning passed like this.

At the end of class, Zhao Yu said: "In the afternoon, martial arts practice, I went to the fire courtyard." From tomorrow, the liberal arts classes will be cut in half and two more courses will be introduced. ”

"Teacher, what's the extra class?"

Cao Pi's little hairy boy asked Zhao Yu.

Zhao Yu walked down the hall, touched his head and killed, looked at the disciples and said, "Introduction to the formation and introduction to the talisman." ”

He explained in detail: "Formations and talismans are both extremely esoteric components of the Immortal Dao, and what I want to pass on to you is the knowledge of formation talismans that is applicable to the level of the general public. In the future, the literature class will be reduced, but it does not mean that the literature class is not important, for you, the talisman and formation are just a skill, but they do not need to be necessary. And the war strategy, the way of governing the country, the piano, chess, calligraphy and painting, and dealing with the world are more important to you. ”

"The two additional courses were compulsory in the previous month. After you all understand some basic knowledge about talismans and formations, the more esoteric ones are elective, and you can study those you like, and you don't have to if you don't like them. ”

"The use of formations, such as the teacher's Taihe Courtyard, the five elements and the four elephants are arrays, which seem to be isolated from heaven and earth, which is too profound for you. And what I'm going to teach you is mainly about the application of formations on the battlefield. ”

"The application of the talisman, as you all know, Meng De used the teacher's soil talisman to treat the flood. The machine car in the courtyard is also the basic embodiment of the way of Fu Zheng. In the future, this aspect of things will become more and more popular, as the children of the Cao family and the Xiahou family, as well as the children who are closely related to the Cao family, you need to know something about this. ”

The addition of the Fu Formation class was not a whim of Zhao Yu.

In fact, it was planned.

When the Fu Gong chariot and ship are about to be popularized, and the Five Elements Battle Array in the army will also be realized, these Cao family and Xiahou family, as well as children like Dian Wei's son who are connected to the Cao family and Xiahou family, as the next generation of the regime under Cao Mengde, they must have a deep understanding of this.

At the very least, you have to know what's going on.

Therefore, it is the right time to open additional courses at this time.

From the second day, the fur of the talisman and the formation was unveiled by Zhao Yu and presented in front of the disciples one by one.

The Fu Gong Formation Course is not only open to disciples, but also the nursing homes in other courtyards, such as Guan Hai, Gao Shun, etc., if they are interested, Zhao Yu allows them to observe.

By the way, the day before, Zhao Yu asked Guan Hai to go to Puyang to get steel, and he came back that afternoon.

Zhao Yu asked for 20,000 catties, and Cao Mengde waved his hand and asked Guan Hai to transport back 50,000 catties.

In the next month, Zhao Yu not only taught his disciples, but also gradually perfected the manufacturing theory of the talisman chariot and ship, and also made considerable experiments in the application of the formation on the talisman chariot and ship, and finally selected the principle of the superposition of the talisman to be used.

Zhao Yu found that it was more difficult to form a formation with a talisman involving the Tao of Yuan Magnetism on a palm-sized mortal material than the superposition technique.

The problem, again, is in the material. If you don't do anything, there is no way to do it. And spiritual materials, which are naturally generated in nature, are almost rare. In this mortal universe, finding spiritual materials is no different from looking for a needle in a haystack, and there is no universality.

The Five Elements and Four Elephant Arrays in the other courtyard rely on this land, and to condense the formation on palm-sized materials, it is only a little bit worse than ascending to the sky.

While experimenting, Zhao Yu systematically recorded the perfected theories.

The first is the issue of materials.

How to integrate steel and jade, Zhao Yu gave a rough alloy refining method. With the function of the steelmaking mother furnace placed in Zhaozhuang, it can be refined. Of course, Zhao Yu did not say this in great detail. Although the steelmaking mother furnace can be refined, the output is not large after all. In the early stage, Zhao Yu planned to realize this step in the assembly-line-like magic weapon that he was about to refine. That is to say, when the magic weapon is refined, it is only necessary to put in the corresponding proportion of stainless steel and jade, and in the first process, this gold and jade material is synthesized.

Asking the question of materials is just a foreshadowing. According to Zhao Yu's records, when people's demand for talisman vehicles and ships increases in the future, this foreshadowing will remind people to study the method of synthesizing gold and jade.

The second is the inscription of the talisman pattern on the frame of the vehicle and ship.

The core module is the power, and after the power is activated, it also needs to be engraved on the mechanical pattern, and the heaven and earth Yuan Qi that is absorbed after the module is activated will do work.

This is a set of fixed talismans, whether it is on a vehicle or a flying machine, it is equally inscribed. It's just size-sensitive.

The truth of this set of talisman patterns lies in the urging of heaven and earth Yuan Qi. The module is activated, absorbing the Heaven and Earth Yuan Qi, and then flowing in the inscribed rune pattern on the mechanical framework, and urging through the rune pattern, so as to do work on the machine.

Therefore, it is a set of fixed rune patterns. As long as you learn it, as long as you don't make mistakes when inscribed, you can make the shell structure of the talisman car and ship in batches.

The third is the control of the talisman chariot and ship.

With the power core and the urging pattern, how to control the start, acceleration, docking, steering, etc. of the car and ship is just like the car in modern time and space, with a steering wheel, brakes, accelerator and so on. This is the operating system.

Zhao Yu fused it into one, and also realized it with the talisman pattern, and gave a drawing.

This is another set of fixed talismans.

When a talisman car is manufactured, the operating table on this drawing is installed, so that the engraved pattern on it is combined with the vehicle and ship, and the operation is realized in the form of a button. Which button to press to connect that rune pattern is activation. Press another button to connect another rune pattern, which is to accelerate. And so on.

On the core module, Zhao Yu didn't say much.

He hopes that the development of the talisman car and ship will reach a certain level, and people can study the truth by themselves.

As long as people understand that the activation module uses electricity, then they can make the most basic talisman chariot ship. Although there is no ability to counteract gravity.

After all, the suspension charm is an obstacle that is difficult for people to overcome.

But when the technology of the foreign civilizations has developed to a considerable level, perhaps they will be able to delve into the use of gravity from it.

In other words, the first-generation talisman chariot ship that Zhao Yu has researched now is actually a relatively advanced talisman chariot ship. It's a model for people. When the world changes, after Zhao Yu leaves this time and space, or something happens, the assembly line magic weapon he refined is sealed or lost, and people can only develop it themselves on the basis of the first-generation talisman chariot and ship.

This is what Zhao Yu is most willing to see.

Zhao Yu is also well-intentioned. Although the talisman chariot and ship he has researched now surpasses the technical level of the people of this era, what he has planted is a seed. He tried his best to reduce the threshold of the Immortal Dao Method, and that's it.
