Ge Lu put down Fangzi, nodded and said, "Yes, this time I was digging the mine, I did find signs of sulfur ore. After all, this northern land was originally a dense place of sulfur ore veins, but it was not easy to mine. With the manpower given to me by the prefect now, I also have to teach many skills, and the speed was not guaranteed."

"These are all small things," Chen Zhi waved his hand, "the main thing is to focus on the future. Didn't I send all those Xianbei people to send? There is still a threat of war, so these people are still under the supervision of the barracks. After the war ends, they will be sent to serve as miners."

Ge Lu asked tentatively: "Listen to the prefect, I still have confidence in the attack of Duan's troops this time, and I have the confidence to win the battle?"

"It's not bad to say that, but you can't prepare for the route of escape in the face of defeat, right?" Chen Zhi laughed, but the main thing he had today was to hand over this prescription to Ge Lu.

Ge Lu understood the key points, and without saying much, he swears, saying that he would never reveal it, because it was obvious that Chen Zhi also grasped some of the key points of their inheritance and had a handle on each other.

However, Chen Zhi knew very well that only when Ge Lu knew the real power of the order in his hand, he would understand the weight. However, he was not worried, because if the things on this order really work, they had to rely on other components, and the proportions and weights inside were also very important.

So he said a few simple words to Ge Lu, and the latter wisely said that he was going back and preparing. Chen Zhi called Chen Ju to come over and asked him to invite Ma Shou and others.

Ma Shou and the others were still three, namely Ma Shou himself, as well as his son Ma Fu and nephew Ma Ji.

The three of them waited in the wing room for a while, constantly guessing the intention of Chen Zhi summoning them to come, and recalling the several objects they had recently started to develop and produce, and their hearts became increasingly unpredictable.

On the way to the back hall, Ma Ji couldn't help but say, "Uncle, what is the purpose of this Prefect Chen calling us and the Taoist Taoist from Tianshidao? Could it be that we both want to cooperate?"

"Ge Lu is not the descendant of the Heavenly Master Dao. It can be said that he has a self-construction system. However, he is also the descendant of the Five Doks of Mi. He cannot come to the forefront. We Mo people inherited the teachings of the nations and the righteous path of heaven, earth and earth. How can we be with him? I think the prefect also understands this. Since he is determined to recruit us, he should always worry about our thoughts, so there is no need to think about these."

As they were talking, the three of them came to the front of the back hall. The other two immediately whispered in a low voice, then stepped forward and asked someone to inform them, and soon met Chen Zhi in the room.

"Old Ma, are you still used to eating and clothing recently?"

"Everything is good, all is good."

Chen Zhi and Ma Shu exchanged greetings first, and after a while, they got to the point.

"I don't know what the finished product you have done?" Facing the Ma family who had just joined the army and were reluctant to act, Chen Zhike didn't have much politeness and just asked.

The horse heard the string song and knew the elegance of the spirit, so he said in a practical manner: "The prefect asked the castings to be mostly used for iron smelting. Because they had to withstand high temperatures and great strength, they had high requirements for the furnace body. My father and son, uncle and nephew also had experience in the past, but relying solely on this technology, the furnace can only be formed. How much fire temperature can it withstand depends on the quality of the material used for smelting. Fortunately, there are several key points and drawings that the prefect explained. This thing can be barely used, but over time, it will be damaged, and it is difficult to use water to blow the air. Because it is difficult to treat, there will be hidden dangers."

"You are an expert in this regard, so I naturally won't argue," Chen Zhi nodded, and suddenly changed his subject, "However, among the many square drawings I have given you, there are some ideas about long cone tubes. Has this part been realized?"

"This tube is used to test the fire temperature. After burning red, it can be used to test the molten iron. After using Taishou's method of stir-frying, pressurizing, and filling steel, it has an amazing bearing capacity, so it was cast first. Could it be this thing...and he also uses it?" Ma Shoudi is old. From Chen Zhi's scales and half claws in his words, he noticed the difference and asked tentatively.

Chen Zhi didn't say it clearly, but instead smiled and said, "That's fine. I will send someone to pick it up in a few days. You can hand over these iron cones to them, and then take out some small charcoal furnaces and coal furnaces I asked you to cast, and let them take them away together."

This was equivalent to confirming Ma Shu's guess, but he did not ask, but nodded and said yes. He couldn't help but mutter in his heart. He thought that Chen Zhi had given them a few drawings, those blast furnaces and furnaces were the key, and they had not been perfected until now. Unexpectedly, at the critical moment, what Chen Zhi needed was actually those seemingly inconspicuous scraps.

"Is this person worried about leaking the secrets, so the design of the so-called blast furnaces is to cover up the eyes and ears? Isn't this just buying a box and returning a bead, but it's actually for that box!"

Ma Shou and others were thinking, but Chen Zhi saw their concerns.

"Don't worry, you guys," Chen Zhi said bluntly: "Since I recruit a few people, I naturally doubt people. I don't doubt people. There is nothing shameful about them. These things can be used now, but they have to do it. It is a temporary new way. The real key is the good iron and good steel in the future. That is the fundamental point, so what you have done is a long way to go!"

"We will do our best!" Ma Shou did not care whether Chen Zhi was true or not, and he acted like he was going through fire and water for him, and his son and nephew followed suit.

"If you have a lot of work, you will be rewarded after the matter is done!" Chen Zhi stood up and bowed, sent the three of them politely out, and then sat back to his seat. After a while, Gongshuhua, Meng Li, the two Mo people who were the first to defect to, also came to the door.

"How many of the two things you did, the single-tab and car cannon?" Looking at these two people, Chen Zhi asked in a very cordial manner, with less alert and temptation in his words, because after this period, Chen Zhi could see that these two people were sincerely trying to rely on themselves. After all, they got benefits, improved treatment, and their families were complete.

Meng Li said: "Reporting to the prefect, the two objects are not complicated, they just need to withstand strength. Because there are ropes on it, it is often difficult for one person to pull up. It takes three or four strong men. Therefore, it is necessary to test it repeatedly and finally select the most solid one and list it as the best. If it can be used multiple times but not loose, it is as medium. If the objects fall after several times of use, it is as low as the rest. "

Gongshuhua said, "At present, there are ten top-grade units, nineteen medium-grade units, thirty-seven low-grade units, and seven top-grade units, seven middle-grade units, and forty-two low-grade units."
