"teacher."

Seeing Zhao Yu coming, Cao Ang and others saluted.

Zhao Yu smiled and said, "Looking at your urge to ask, I probably didn't come at the right time."

"The teacher is so serious."

Zhao Yu was very strict when teaching them, but in addition to class, he was very close to his disciples and made harmless jokes from time to time, and the disciples were no longer surprised.

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

I chatted with Cao Ang and the others for a while, and the class started again, and the whole morning passed like this.

When the class was over, Zhao Yu said: "In the afternoon, you will go to the Fire Academy. From tomorrow, the literary class will be reduced by half and two additional courses will be added."

"Teacher, what class will be added?"

Cao Pi asked Zhao Yu.

Zhao Yu walked out of the hall, touched his head and looked at the disciples and said, "Introduction to formations and talismans."

He explained in detail: "Formation and talismans are extremely profound components of the immortal path. What I want to teach you is the knowledge of formations and talismans that are suitable for the public. The reduction of literary classes in the future does not mean that literary classes are not important. For you, talismans and formations are just a skill, but they do not need to be necessary. And military books, war strategies, the way to govern the country, piano, chess, calligraphy and painting, and dealing with people are more important to you."

"The two additional courses are compulsory courses one month ago. After you all understand some basic knowledge about talismans and formations, those that are more profound are electives. Those who like them can study them, and those who don't like them do not have to."

"The application of formations is like the teacher's Taihe Villa, where the five elements and four symbols are formed, and it seems to be isolated from the world. This is too profound for you. What I want to teach you is mainly about the application of formations on the battlefield."

"You all know that the application of talismans is used by Meng De to treat floods. The talismans in the courtyard are also the basic embodiment of the way of talismans. In the future, things in this area will become more and more popular. As children of the Cao family and Xiahou family, as well as children who are closely connected with the Cao family, you need to know something about this."

The addition of the talisman formation class was not Zhao Yu's sudden idea.

Actually, there was a plan.

When the talisman carriages and ships are about to become popular, the Five Elements Battle Formation in the army will also be realized. These children who are connected with the Cao family, Xiahou family, like Dian Wei's son, who are connected with the Cao family, as the next generation of the regime under Cao Mengde, must have a deep understanding of this.

The most time, you have to know what's going on.

Therefore, it is time to add courses at this time.

Starting from the next day, the fur of the talismans and formations was unveiled by Zhao Yu and presented them one by one to the disciples.

The talisman formation course is not only open to the disciples, but also the guards in other courtyards, such as Guan Hai, Gao Shun, etc., if you are interested, Zhao Yu allows them to listen.

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

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

In the next month, while teaching his disciples, Zhao Yu was gradually improving the manufacturing theory of talisman carriages and ships. At the same time, he also used the formation on the talisman carriages and ships for quite some experiments. In the end, he chose the best principles of talisman superposition.

Zhao Yu found that it is more difficult to form a formation on a mortal material the size of a palm-sized body to use talismans involving the path of Yuanmagnetics than superimpose the technique.

The problem still lies in the materials. No matter how much material is, it is impossible to do anything about it. However, spiritual materials are naturally generated in nature and are almost rare. In this mortal universe, it is no different from finding spiritual materials and finding needles in a haystack. It is not popular.

The Five Elements and Four Symbols Formation in the Villa relies on this land, and the formation needs to be concentrated on the palm-sized material, it is only a little worse than climbing the sky.

While experimenting, Zhao Yu recorded the improved theories systematically.

The first is the material issue.

Zhao Yu gave a rough alloy refining method for how to integrate steel and jade into one. It can be refined with the function of the steelmaking master furnace in Zhaozhuang. Of course, what Zhao Yu said in detail is not very detailed. Although the steelmaking master furnace can be refined, the output is not large after all. In the early stage, Zhao Yu planned to implement this step in the magic weapon he was about to refine like an assembly line. In other words, when the magic weapon is refined, only the corresponding proportion of steel and jade needs to be invested, and this kind of gold and jade material is synthesized in the first process.

Asking up materials is just a foreshadowing. According to Zhao Yu's records, when people's demand for talismans and ships becomes increasingly greater in the future, this foreshadowing will remind people to study the methods of synthesizing gold and jade.

The second is the inscribed talismans and Taoist patterns on the structure of the vehicle and ship.

The core module is power, and after the power is activated, the Tao pattern engraved on the mechanical side is also required to absorb the heaven and earth primordial qi after the module is activated.

This is a set of fixed talisman patterns, which are engraved on vehicles and ships, and are only different in sizes.

The fundamental reason for this set of talisman Taoist patterns is to activate the primordial qi of heaven and earth. The module is activated, absorbing the primordial qi of heaven and earth, and then flows in the engraved talisman Taoist patterns on the mechanical structure, and activates the talisman Taoist patterns, thereby doing work on the machinery.

Therefore, it is a set of fixed talisman patterns. As long as you learn it and do not make any mistakes when engraving it, you can create the shell structure of the talisman car and ship in batches.

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

With the power core and the activate road pattern, how to control the start, acceleration, stop, steering, etc. of the car and ship, just like modern time and space cars, there is a steering wheel, brake, accelerator, etc. This is the operating system.

Zhao Yu integrated it into one, and also realized it with talismans and Taoist patterns, and gave a drawing.

This is another set of fixed talismans and Taoist patterns.

When a talisman car is manufactured, the operating table on this drawing is installed so that the inscribed Taoist patterns on it are combined with the car and ship, and the operation is implemented in the form of a button. Which button is pressed to connect the Taoist patterns of the Taoist patterns of the Taoist patterns of the Taoist patterns of the Taoist patterns of the Taoist patterns of the Taoist patterns of the Taoist patterns of the Taoist patterns of the Taoist patterns of the Taoist patterns of the Taoist patterns of the Taoist patterns of the Taoist patterns of the Taoist patterns of the Taoist patterns of the Taoist patterns of the Taoist patterns of the Taoist patterns of the Taoist patterns of the Taoist patterns of the Taoist patterns of the Taoist patterns of the Taoist patterns of the Taoist patterns of the Taoist patterns of the Taoist patterns of the Taoist patterns of the Taoist patterns of the Taoist patterns of the Taoist patterns of the Taoist patterns of the Taoist patterns of the Taoist patterns of the Taoist patterns of the Taoist patterns of the Taoist patterns of the Taoist patterns of the Taoist patterns of the Taoist

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

He hopes that the talisman car and ship will develop to a certain level, so that people can figure out the truth on their own.

As long as people understand that the activation module uses electricity, they can create the most basic talisman car and ship, although they do not have the ability to offset gravity.

After all, the hanging symbol is an obstacle that people are difficult to overcome.

But when the technology of the heretic civilization develops to a considerable level, perhaps they can develop the technology of applying gravity from it.

In other words, the first generation of talisman car and ship developed by Zhao Yu now is actually a more advanced talisman car and ship. It is a model for people. When the world changes and Zhao Yu leaves this time and space, or if something unexpected happens, the assembly line magic weapon he refined is sealed or lost, and people can only develop it themselves based on the first generation of talisman car and ship.

This is what Zhao Yu is most happy to see.
