While gradually completing the theory of talisman car and ship manufacturing, Zhao Yu was also preparing for the refining of the Five Elements Array Flag and the assembly line magic weapon.

The material of the Five Elements Array Flag, Zhao Yu took silk and spirit wood.

The silk is the high-grade silk sent by Cao Mengde, while the spirit wood can only be intercepted from the pear tree by the Yuanqi Pond in the small world of Chaos Beads.

To find the spirit wood in the outside world is tantamount to ascending to the sky, it is too difficult.

This set of array flags is not very demanding, Zhao Yu understood what Cao Mengde meant, in order to prevent the backlash of the army that has been refined into the Five Elements Battle Array, it is nothing more than using the power of the Five Elements Array Banner to slightly stir the Five Elements Yuan Qi and block the connection between the individuals in the battle array, so that the Five Elements Battle Array cannot be condensed.

Therefore, the material does not need to be too strict, and it is enough to have spiritual wood. Silk is just an auxiliary.

As for the assembly line magic weapon, after Zhao Yu pondered it, he decided to refine it into the form of a furnace tripod. Just like the steelmaking mother furnace in Zhaozhuang. This magic weapon is a little more profound than the Five Elements Array Flag. For the refining of the Five Elements Array Banner, three or five forbidden methods are more than enough, and the furnace Ding assembly line requires at least six to nine forbidden methods, which is close to the level of medium-grade magic weapons.

As for the materials, Zhao Yu planned to use the real gold and jade that had been quenched by mana as the furnace tire, and the outer shell was made of ordinary gold and jade refined by ordinary means.

Zhao Yu wrote and painted on a roll of brocade silk: "The furnace is one zhang two feet three inches high, and the circumference is one zhang nine feet nine inches... The furnace tires are nine feet nine inches high, and the circumference is one foot two feet three inches... 128,000 catties of steel and 99,000 catties of jade..."

Called Guan Hai and handed him the cloth that recorded the material demand data: "Go to Puyang and give this brocade to Meng De." Tell him I'm going to see the material in three days. ”

Guan Hai bowed: "Yes." ”

In this way, the refining of the two magic weapons was put on the agenda.

Before the materials for refining the furnace tripod arrived, Zhao Yu made the embryo of the Five Elements Array Banner. The silk is woven into a flag, and the spirit wood is combined into one. The production of the embryo is only the first step, and then it is necessary to enter at least three layers of forbidden methods into it, but before that, it is necessary to carry out a certain degree of cultivation of the embryo.

So Zhao Yu put the five flags into the eyes of the Five Elements Formation in the other courtyard, and used the abundant and rich Five Elements Yuan Qi in the eyes of the array to nourish them.

This process lasts about three months, that is, it will be officially started after the beginning of the year.

The materials needed for the furnace then arrived.

This time, Cao Mengde came over in person.

For Cao Mengde, no matter what Zhao Yu needs, he will not say half a word. With more than 100,000 catties of steel and tens of thousands of catties of jade, Cao Mengde didn't care at all. What he cared about was what Zhao Yu needed these materials for.

Naturally, Cao Mengde thought of the Fu Gong car and ship that Zhao Yu had mentioned at the beginning.

In addition, it has entered late autumn, and the autumn harvest has been completed in various places, and there is a little leisure in government affairs. What's more, the pill that Zhao Yu asked Xi Zhicai to bring back last time has bottomed out, and he has long planned to bother Zhao Yu to see if he can fight the autumn breeze.

Seeing that Guan Hai arrived in Puyang, he didn't say a word, explained the affairs at hand, took Dian Wei Xu Chu, followed the convoy transporting materials, and went straight to Taihe Courtyard.

"Sir!"

Cao Mengde's face was full of red light.

Zhao Yu smiled: "Meng De." ”

The two walked into the courtyard with their arms.

Cao Mengde said: "Mr. told me about the Fu Gong car and ship last time, oops, speaking of the machine car in Mr.'s courtyard, my eyes are extremely hot." ”

Zhao Yu smiled: "Meng De guessed?"

Cao Mengde nodded and said: "Mr. wants so many materials at once, I think about it, it's nothing more than this." ”

Zhao Yu said: "Go in and talk." ”

Once you enter the Taihe Courtyard, there can be no danger. Cao Mengde waved away Dian Wei Xu Chu and went all the way to the study with Zhao Yu.

In the study, Zhao Yu asked Cao Mengde to sit down, turned around and took down eighteen rolls of thigh-thick brocade silk on a bookshelf, and placed them on the desk one by one.

Then he said, "This is the result." ”

"Oh!"

Cao Mengde looked at the eighteen scrolls of brocade silk, couldn't help but show his eyes, couldn't wait to take a scroll, gently unfolded it, looked at the patterns and explanations on it, and his expression gradually became excited.

Zhao Yu said: "Among these eighteen volumes of brocade silk, it is about the manufacturing process of talisman cars and ships. I've perfected it. When you go back, take them with you, and then find someone you can trust and teach them. ”

"The first three volumes are theories, and you'd better hide them yourself. Volumes 4 to 6 are materials, volumes 7 to 15 are the patterns of the shell of the vehicle and the way to engrave them, and the last three volumes are operations. In addition to the core theory of the first three volumes, the last three parts, you separate them, do three different processes, independent of each other, and finally establish a combined process, so as to ensure that the secret is not leaked to the greatest extent. ”

Cao Mengde put down the brocade silk and couldn't help nodding again and again: "Mr. is thoughtful, I remember." ”

Zhao Yu sat down: "The most important thing in the Fu Gong car ship is the core power module. The power of the carriage is the horses, and the power of the building boat is the people. And the power of the Fu Gong car and ship is the Heaven and Earth Yuan Qi. I cut and cut, thought and thought, and came up with a way that I couldn't cut anymore, and I could make core modules in batches. But for the common people, it is still very difficult, and I am afraid that it is difficult for anyone to understand. However, this does not matter, when the society develops to a certain extent, there must be capable people who use their own methods to reinterpret and realize. ”

"I'll refine a magic artifact and use it to make the core module. The large amount of materials used to refine this artifact this time is the material used to refine this magic weapon. The magic weapon is too subtle to understand. But I can't help it, I really can't reduce the mysteries of the Immortal Dao. However, in the theory of the first three volumes, I pointed out that according to the reasoning, if you let the most trustworthy people study it, it may not be impossible to achieve your own manufacturing from generation to generation. ”

In the open-book theory, Zhao Yu pointed out the use of electricity. Although not detailed enough, there is a clear direction.

Cao Mengde also knew that since the immortal method was an immortal method, it must not be applicable to mortals, and he also knew that Zhao Yu had good intentions, and he didn't know how much effort he had spent on studying. For a while, the beard trembled.

"Sir... I really don't know how to thank you. ”

Zhao Yu shook his head: "It's not necessary. I'm having a lot of fun, too. ”

Zhao Yu said with a smile: "As for the Five Elements Array Flag, I have refined it into an embryo and am in the process of cultivation. At most, it will be in your hands in March next year. When the time comes, you have to go through a confession process. After recognizing the Lord, only you and your direct blood relatives can use it, and outsiders can't use it when they get it. ”

Cao Mengde didn't know what to say. Everything was conceived for him, and any loopholes and negligence were blocked. The heart is comfortable, grateful, needless to mention.
