Feeling the strangeness in his eyes, Chen Zhi was stunned for a moment, and then suddenly came back to his senses and realized what this change represented.

"The phantom in my eyes usually appears when I encounter strange luck, but except for the sand table in my room, this kind of reaction has not appeared on dead objects in the past, and it can only be seen in living people."

The thought in his heart was fleeting, but Chen Zhi did not delve into it, but stepped forward and carefully looked at the common blade that had shaped a rough prototype.

It is said that it is a sword, but it is actually very crude, because this is not the shape of a long sword intended for mass production, and this is not an arsenal that really builds weapons, but a laboratory specially planned by Chen Zhi for new iron smelting, alchemy, and forging processes.

Because it is an experimental nature, the first step is not to solve the problem of "whether it is good or not", but "whether it is or not", so the pursuit of the objects that appear at the moment is not practical, but to make sure that it can be made, and then after estimating the cost and output, the process and mass production can be further discussed.

The sword embryo presented in front of Chen Zhi at this moment was like this, and Chen Zhi looked up and down.

Perhaps because of the lack of preparation, there are still many roughness on this blade, and the whole is relatively dark, but it has a cold glow, which makes people feel dangerous when they look at it.

When Chen Zhi observed the sword embryo, Li Wei next to him couldn't help but get nervous, like a child waiting for the test results, always paying attention to Chen Zhi's expression, after all, this trial workshop was handed over to him by Chen Zhi to manage, although there were many achievements before, but most of them were under Chen Zhi's guidance to reproduce the techniques of other places in Xinhan.

To put it simply, in the past few months, the achievement of this trial workshop is to make the originally backward iron smelting level of Daijun catch up with the average level of this era, such as the weapons made by the current Daijun workshop, that is, the carburizing method and the steel frying method each account for a part.

Chen Zhi raised his head at this time, noticed Li Wei's expression, and immediately knew what he was thinking, and couldn't help laughing: "Don't do this, what is the quality of this steel, in fact, I can't tell it, after all, there is a specialization in the art industry, and I want to learn from you in this part." ”

Li Wei was startled, waved his hand again and again, and said that he didn't dare.

Chen Zhi didn't say much, just said: "You just have to let go and do it, ask for money and people, or if there is any need for objects, repair it, I know that this thing can not be done at a time, there must be a lasting investment, in fact, you did it well before, and now these attempts are my few words of guidance, this is just the direction, whether it can be achieved depends on the luck, before the mastery of these plastic steel methods, it is very rare, with these methods, we can rely on our own manpower, iron ore, to build weapons out, Invisibly, a lot of money has been saved, and autonomy has been obtained, and there is no need to be subject to Youzhou. ”

After Chen Zhi's words, Li Wei put his mind at ease, but still introduced the characteristics of this newly acquired steel, and the little scholar Chen Wu, together with many guards, retreated very knowingly to the side to prevent it from entering his ears-

Sometimes, it's not a good thing to know too much, even if you're not afraid of being remembered, if there is a mistake, you will become a suspect in the first place.

After a few people retreated, Li Wei also let go of his scruples, and said directly: "This new steel is according to what the Lord mentioned, with the idea of 'miscellaneous refining and raw steel', and it has failed more than 100 times before and after, but under your reminder, I went to consult a few Taoist leaders, and got their reminders in alchemy and alchemy, mainly to fill the steel method, control the ratio of pig iron and iron, melt the pig iron, pour it into the wrought iron, and then supplement it with the beating of the hundred refining method to discharge the impurities, so as to become this method, the finished material is strong and sharp, and it is more good willful, which can be described as the top grade!" When he said that, he was all excited.

Chen Zhi nodded slightly, he can understand the approximately, after all, this steel filling method is what he pointed out, but according to the original historical development, this set of technology will mature in the Northern and Southern Dynasties, but then the Tang, Song, Yuan, Ming and other periods, but also on the basis of the original to further improve, it can be said to be a basic skill, once mastered, the development potential is great.

However, the road still has to be taken step by step, in order to establish a solid foundation, as well as build a complete supporting system and ecosystem, Chen Zhi still let Li Wei slowly try to build a forging system from scratch.

After all, in Chen Zhi's view, Yidaijun has been prepared at the moment, and there is no need to deliberately pursue the lead in the material of the weapon, because this steel filling method, at the beginning, the advantage is not obvious, and its supporting production facilities, without half a year and a year, can not be erected, it is simply not in time, it is better to use it as a technical reserve, not large-scale promotion, continue to improve the technical level, after all, the academic definition of the Northern and Southern Dynasties, according to historical inertia, in the original history will also start a hundred years later, Chen Zhi can afford to wait.

On the other side, Li Wei obviously opened the chatterbox, and said over there: "If this method of filling steel is properly operated, it can discharge the carbon ash and impurities in it together. ”

When Chen Zhi heard this, his heart moved, and he suddenly remembered that the last advantage of coal and coke couldn't help but encourage a few words, because this was not Chen Zhi's direct idea, but just pointed out a general direction, and at the moment Li Wei was groping for himself.

After saying this, Chen Zhi suddenly asked about something: "Since the new steel has been completed, I don't know if you have ever tried it, can you withstand the high temperature and then make it into a cylinder shape?" ”

Li Wei shook his head and said: "I haven't tried this yet, but judging from the current situation, it is not optimistic." ”

Chen Zhi nodded, and said, "This matter is not reluctant, let's take it step by step." Then he met with the other craftsmen in the workshop, greeted them one by one, and when he saw that the time was almost up, he walked out.

Chen Wuru, who had been waiting for a long time and was a little stuffy and uncomfortable, rushed out as soon as he was amnesty, and then ripped open his clothes and panted.

When Chen Zhi came out, he found that he was soaked all over his body, so he sighed, he had worked so hard this time, Li Wei and the others were here every day, it was really hard.

I just wanted to encourage here, but suddenly there were footsteps rushing over, but it was Tong Hai, who gave the order, and directly brought a message.

"Did the Huns move troops and horses at the border?"

After Chen Zhi learned the information, his brows furrowed slightly, feeling that things were not simple, and he was even more solemn when he contacted the news about the Xiongnu in recent days.

"It seems that the second captive should almost be put back."

Saying this, his heart suddenly moved, and there was a feeling of blood gushing up, as if something had happened, but it quickly dissipated, and he temporarily pressed down his doubts and confirmed some details of information with Tong Hai.

But while he was talking, there were footsteps hurrying over, but the person who came over this time was Chen Duo.

The manager of the Chen family in Dai County, who was sweating profusely at this time, when he saw Chen Zhi, he sped up a few steps, came to him, and couldn't take a break, so he said breathlessly: "Lord, madam...... Madame she ......"
