"Your Majesty, the minister thinks that all the scholars are right!" Wen Tiren said with a smile on his face, "It's not very appropriate to put this copyright patent office in any yamen!" Therefore, the minister suggested ......"

Hearing this, the six Shangshu couldn't help but prick up their ears and stared at Wen Tiren's back, waiting to see what constructive results Shoufu had.

Emperor Chongzhen saw Wen Tiren's smile, obviously there was a proper solution, and he couldn't help but be a little curious, and nodded to signal Wen Tiren to finish.

"The minister suggests that this copyright and patent office should be directly under the cabinet!"

As soon as Wen Tiren said this, the six Shangshu understood that this matter was a competition between the snipe and the clam for the benefit of the fisherman.

When Emperor Chongzhen heard this, he thought about it and nodded: "That's okay, so let's do it, this copyright and patent office will be directly under the cabinet, and the celebrant will also send people to prepare this new yamen together." ”

"......" This time it was Wen Tiren's turn to be speechless, and the celebrant also intervened.

Emperor Chongzhen saw that this matter was almost a result, and he was still worried about other things, so he broke up the meeting early and set up a military battle.

This time, he didn't just see the eunuch of the Palm Seal of the Military War Bureau and told him to do things. Instead, in the lobby of the War Bureau, it was announced that all the leaders and experts of the craftsmen would be present.

After greeting him, Emperor Chongzhen said to everyone below: "The new army will soon use artillery, but the artillery cycle you cast is too slow, I can't wait." I asked you to figure out a way before, but now there is a solution? ”

All the craftsmen under the "......" were silent, and this thing could be imagined if they thought about it.

As soon as Emperor Chongzhen saw them like that, he knew that there was no result. At this time, he didn't make a fuss, so he ordered Li Junfeng, the craftsman in charge of artillery casting, and said: "Put the difficulties up, work together, and see if they can be solved!" ”

was pointed, Li Junfeng had no choice but to reply: "Today's casting cannon method is the West Yi of learning, and the outer fan and the shape core are combined and then cast molten iron. However, the exterior and core are made of clay and can only be used until they are dry. However, even after charcoal baking, it is often dry on the outside and wet on the inside, so it must be dried until the inside is also dry. In this way, it will take about two months for the weather to be right. As long as there is a little bit of dry in the mud mold, moisture is generated during casting, and the cast cannon often has honeycomb holes, which is defective. ”

As he spoke, Li Junfeng was also proficient in his specialty, so he consciously added: "There is also a lot of molten iron that often disturbs the core when it is poured into the mold, so that the cast gun chamber is not in the middle of the gun body." When the cannon is cast, the clay mold must be broken, so that only one cannon can be cast in a clay mold. In addition, it is necessary to repeat before. Currently, only one good gun is available for every 100 guns cast. ”

Emperor Chongzhen nodded when he heard this, these were the shortcomings of the clay mold cannon that he had known in advance, after Li Junfeng finished speaking, he looked at everyone and asked: "Who has to supplement the difficulty of casting cannons with such methods?" ”

Another craftsman, Liang Yulin, saw the emperor praising Li Junfeng, and after a little hesitation, he said: "Your Majesty, the clay needed for the clay mold needs to be made of very familiar clay, so it will take a lot of time and manpower!" ”

Emperor Chongzhen listened, nodded approvingly, saw that the others didn't say anything more, then looked at them and asked, "Then have you ever thought about it, since the clay mold casting method has so many shortcomings, why don't you use molds of other materials to cast?" ”

"Your Majesty, Xiyi uses this method to cast artillery!" The head craftsman Li Junfeng may have talked to the emperor a lot, and he also knows the emperor's temperament somewhat, so he has the courage to play.

When Emperor Chongzhen heard this, he immediately stared at him and said, "What's wrong with Xiyi's clay mold?" Does it mean that you can't use other materials as molds? For example, the iron mold casting method handed down by our ancestors, is it okay? ”

"Your Majesty, this one is different." Li Junfeng felt that his authority was being questioned, and hurriedly explained, "Iron mold casting is indeed available, and it is convenient and has many benefits, but it is only to cast some small utensils such as sickles and hoes, and it is not possible to cast small utensils such as artillery!" ”

"Is it okay to break up the cannon into smaller dots?" Emperor Chongzhen's thoughts would not be bound by the times, so he immediately asked.

Li Junfeng was stunned when he heard this, he had never thought about it. It's because when he learned the ability to cast cannons from Xiyi, he has been using clay molds!

In addition, the craftsman Liang Yulin was like an initiation, and his eyes lit up and said, "Your Majesty, maybe it's feasible!" ”

When Emperor Chongzhen heard this, he was very happy, so he said with a smile: "Yes, then go and try to do it." Don't be afraid to fail! I believe that technology is experimental! ”

At this time, Li Junfeng also came back to his senses, with his years of experience, after thinking about it a little, he was also very surprised, and hurriedly played: "Your Majesty, or maybe it's really feasible!" ”

Emperor Chongzhen laughed when he heard this, and he couldn't help much in terms of specific implementation. Since these experienced craftsmen said that it might be possible, then let them do it.

So, he smiled and said, "Whoever can find a new and better way to forge artillery will be rewarded with great reward." Does the mason Tang Binghong know? As long as you can make it, he is your tomorrow! ”

The invention of cement, Tang Binghong is only the specific implementer, but he has become a hot craftsman today, and his status has improved, not to mention money, just in terms of respect, these craftsmen are blushing. At this time, when I heard what the emperor said, I was suddenly full of energy, as if I had been beaten with chicken blood.

In the original history, the iron mold casting cannon method was invented by Gong Zhenlin, the county at that time, at the end of the Qing Dynasty. Now, under the guidance of Emperor Chongzhen, a traverser, although there are still some technical problems to be overcome by casting cannons from iron molds, these technologies are not a problem for the Chinese people.

For example, the positioning method adopted between the petals and sections of the iron mold can refer to the ancient pottery fan and the metal type mortise and tenon positioning process measures. Another example is the iron mold handle casting, the use of double-layer paint, etc., is also the conventional technique of traditional casting.

When Emperor Chongzhen left the military battle, he was of course happy in his heart. Contrary to his mood at this time, Zheng Zhilong, a coastal defense guerrilla in Fujian, can be said to be extremely depressed at this time.

Ding Ding, who rushed back from Jingshi, told him about the situation after his rival Li Kuiqi was escorted to Beijing, and Zheng Zhilong was so angry that he directly threw a set of beloved tea sets. Fighting for life and death, how many days and nights of planning, how many benefits were exchanged, and the result was like this!

He was depressed, and suddenly the holy decree arrived, telling him to go to Jingshi immediately. This made him suspicious, and before he could come up with a result, he heard a report from his subordinates: "Jinyi Wei Xiaoqi Liu Jinsheng is here!" ”
