He sat down quietly and browsed Yuan Rang's manuals and notes page by page, but his mind flew to Hu Fu: "Hu Fashun supports both the combustion pump and the Fa Gong, what is his purpose?"

"He likes new technologies? No, if that's the case, why doesn't he study together in this basement? He wants to give His Majesty credit and take the results for himself? No, if so, he can't fool ** and Tang Wanyuan. ”

"What should I do if I think about this matter with the method of cutting?" After understanding the method of cutting, his thinking became much more active, and the things that had happened around him in the past few days were suddenly connected by him, and a bold idea appeared in his mind.

"Whether it is a magic gun or a combustion pump, it requires a large amount of iron, sulfur, saltpeter and other materials, which are all restricted by the imperial court. Hu Fashun wants to get the materials conveniently, and the best way is to directly grasp the ore, is he ......?"

Thinking of this, Shi Yuanji felt a chill behind his back, and he was not only moved by the practicality of the cutting method, but also shocked by Hu Fashun's boldness.

"I'm afraid I can't save Jiang Renyun, he likes to be inflammatory, I can't stop him at all. Ke Yuanrang Senior Brother is not this kind of person, I have to stop him. ”

"Yes, first give a formula for a powerful magic medicine, it is nothing more than a higher purity, and you can deal with it with Master's knowledge. As for steel, although I don't have the research ability of Senior Brother Yuanrang, I can reverse the weakened version of Qingpei Steel. ”

"Although they are all opportunistic methods, as long as Yuan let Senior Brother get rid of Hu Fashun, what can not be done? As long as you get rid of Hu Fashun and study new magic drugs and new steel, you can do it slowly. ”

With his train of thought set, he immersed himself in the manual, waiting for the night to come.

In the Taiwei Yuan, an old woman stood in the Taiji Fish Array, speaking to the Tai Students in the Yuan with full of energy, not at all like an old man with gray hair.

"You've all seen me and received it from me, so let me introduce myself. Old body Fang Yueying, I mainly tell you about gold and iron research, and I am also in charge of the needle and hat bureau. ”

"Today is the first lesson for you, and the other Masters should have talked to you about the truth. They talk about their subjects, and they all say that if they go down this path, they will get the appearance of the truth, or at least the tip of it. ”

"I would say the same thing, and I would do the same. But I want to tell you first, those students who majored in gold and iron science, your path of seeking truth is not easy, and the road of chasing fame and fortune is not easy to follow. So, no matter which path you choose, it's best to settle down and learn. ”

As soon as the words fell, the students who majored in Jin Tieke wailed, as if they regretted that they had majored in Jin Tieke.

"There's nothing really simple in this world, young people. Fang Yueying looked at the wailing Tai student, and a smile spread on her face. "Well, we don't need any advanced theories or complicated definitions for this subject, just facts. ”

As she spoke, she picked up a piece of wrought iron the size of a palm and held it in front of her: "I will teach you how to identify materials, and how to cast them, they are all facts." You just have to look for them and know them. ”

Fang Yueying condensed a stream of blue mana at her fingertips and shot into the wrought iron. The wrought iron floated in the air, trembling slightly, as if it was alive.

In the wrought iron, the blue mana flow slowly flowed out, breaking the thread with the wrought iron lotus root, condensing into an illusion. "See, this is the structure of wrought iron, iron, carbon, the two elements are densely combined together, and it becomes wrought iron. ”

The Tai Chi students outside the Tai Chi fish exclaimed in surprise, and they all looked at the wrought iron floating in the air, their eyes revealing curiosity.

"This is the method that you will study and study in the future, called the method of the shadow cone, which is a rudimentary method of probing the structure of matter. What you have to do is to explore the properties of matter and make better materials of gold and iron. ”

Some students have begun to imitate Fang Yueying's technique and probe the objects in their hands. Most of them failed, and only a few succeeded, including Princess Nayu beside Shi Yuanji, who successfully mapped the mana structure diagram of her sleeve.

"As your cultivation progresses, the more matter that can be detected by the method of the Shadow Cone will be, so don't worry if you fail. Later, I'll leave it to you for more complex methods. ”

"It's a very boring process, and there's no room for shortcuts. You may not be able to find a gold that meets your needs, and you may fail in your hopeful attempts, but this is our fate. ”

I'm afraid that the second senior brother has a deep understanding of this, Shi Yuanji said in his heart.

"Now, I'm going to teach you some ways to make gold and iron. Of course, there are some that you have seen, which is the blacksmith's method of striking iron. Others, which require mana support. ”

In the following time, Fang Yueying talked about some basic smelting skills. Shi Yuanji carefully took notes, corresponding to the assumptions in his mind one by one.

To tell the truth, these contents have been summarized by predecessors, and they are clearly organized but also boring. After a while, there were already a lot of students yawning, obviously unable to listen. Even Nayu peeked at Shi Yuanji from time to time, and she was a little bored.

Shi Yuanji was not bored with this knowledge.

His master is a doppelganger of Xihe, who is naturally powerful, and spells are his instincts, which are easy to come by. Therefore, he could not accurately describe a lot of knowledge, so he could only engrave dragon patterns for Shi Yuanji to memorize.

Now, with the systematic knowledge of Chengyun Pavilion, the originally incomprehensible dragon pattern is suddenly integrated. Various thoughts flashed in his mind, among which the speculation about Qing Pei Gang was even more clearly visible.

"Perhaps, I can really find an opportunistic way to keep the second senior brother away from the hidden danger of Hu Fashun. He muttered quietly.

"Brother Yuanji, what are you talking about?" Nayu looked at him curiously with watery eyes.

"I didn't ...... It's nothing. Shi Yuanji lowered his head in embarrassment and continued to write his notes.

Back in the Treasure Pavilion, Shi Yuanji couldn't wait to turn into the basement and dig out the white steel he was looking for from the pile of steel.

"Xiao Shi, don't be in such a hurry, it's the same for tomorrow's research. Yuan Rang put the key on the desk and said with a smile. "Are you in such a hurry, do you think of something?"

"I already have a bold idea, Second Senior Brother, you have to help me. He took out his notes and flipped to the plan to weaken Qing Peigang.

"White copper, red lead, wrought iron, colored stone, the basement has these materials, you want them now?"

"Yes, now. ”

Yuan Rang said patiently while looking for materials: "Xiao Shi, I know that after listening to Fang Servant's subject, you must have some ideas to verify. But I want to make it clear first that the failure rate of refining materials is very high. If you fail, you must not be discouraged. ”

"Why do you say that?" Shi Yuanji wondered a little, did he look like a fragile person?

Yuan Rang put all the materials on the desk and said solemnly: "I have seen many classmates of Jin Tieke, but they always can't refine the materials they want, and in the end they find a short-term view." I'm also reminding you, after all, you're majoring in law, so there's no need to be like them. ”

What do you think of me, he smiled bitterly in his heart.

"Don't worry, second senior brother, it won't. ”

"That's good, I've got the basement key here, and you should go back early. With that, Yuan Rang left the basement.

Shi Yuanji looked at the colorful ore and recalled the contents of the Divine Record.

"The God of War...... Its land is full of white copper, colored stones, and red lead...... Thunderstorms followed, lightning flashed and thundered, and Tai Sui also ...... All the swords forged by Qing Pei Gang are more than 100 zhang, and they are full of thunder and might......"

Judging from the materials given by Fang Fuji, white copper should be enough to increase toughness, about three percent should be enough, color stone is the least, one percent is about the same, and the carbon in wrought iron is still too little, so replace it with twice the proportion of white steel.

"Now, it's up to me to see if I can simulate the environment of the military gods. Shi Yuanji muttered, arranged a small exhaustion array in the basement, moved all the necessary materials into it, and let them float in the air.

"The steel suitable for combustion pumps has to be tough, hard, and resistant to high temperatures, which is really troublesome. Looking at the test standards and failure records left by Yuan Rang, he finally understood Yuan Rang's advice.

That's a foot-thick record of failure written on hemp paper!
