"Your Majesty, I think all the ministers are right!" Wen Tiren said with a smile on his face, "It is not very appropriate to place this copyright and patent office in any yamen! Therefore, I suggest..."

Hearing this, the six ministers couldn't help but prick their ears, staring at Wen Tiren's back, waiting to see if the Prime Minister had any constructive results.

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

"I suggest that this copyright and patent office be directly affiliated with the cabinet!"

As soon as Wen Tiren said this, the six ministers understood that this was a fight between the snipe and the clam and the fisherman benefited.

When Emperor Chongzhen heard this, he thought about it and nodded and said, "That's fine, so that's it. The copyright and patent bureau will be directly under the cabinet, and the Silijian also sent someone to prepare the new yamen."

"..." This time it was Wen Tiren's turn to be speechless. As expected, Si Lijian also intervened.

Seeing that this matter had almost had a result, Emperor Chongzhen was still thinking about other things, so he left early and set up a military battle.

This time, he did not just see the eunuch in charge of the military commander and ordered him to do things. Instead, he sent an order to meet all the craftsmen and experts in the military commander's lobby.

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

"..." All the craftsmen below shut up, and this matter could be thought of just thinking about it.

When Emperor Chongzhen saw them like that, he knew there was no result. At this time, he did not make a fuss, so he lit up the head of the craftsman responsible for the casting of artillery and said, "Put the difficulties up, work together to see if they can be solved!"

After being fired, Li Junfeng had no choice but to answer: "Now, using the casting cannon method is to learn from Western barbarians, and then cast iron and water. However, the outer pattern and core are made of clay and must be dried until they are thoroughly dried. However, even after being baked by charcoal, it is often dry on the outside and wet on the inside, so it must be dried until it is thoroughly dried. In this way, the weather will take about two months. As long as there is a little bit of dry in the mud mold, moisture will be generated during casting, and the cast cannons often have honeycomb holes, which is a defective product."

As he was talking, Li Junfeng was also skilled in his professional matters and consciously added: "There is also the iron water often disturbs the core when pouring into the mold, so that the cast gun chamber is not in the middle of the gun body. When the casting gun is completed, the mud mold must be broken. In this way, one mud mold can only cast one gun. In addition, rebuilding must be repeated before. At present, about every hundred castings are available."

Emperor Chongzhen nodded when he heard this. These were the shortcomings of mud mold casting cannons he had learned in advance. After Li Junfeng finished speaking, he looked at everyone and asked, "Who cannons are more difficult to make such methods?"

Another craftsman, Liang Yulin, saw the emperor praise Li Junfeng, and after hesitating, he spoke: "Your Majesty, the clay required for clay molds requires extremely pounded clay, so it takes a lot of time and manpower!"

After hearing this, Emperor Chongzhen nodded in praise, and saw that the others did not say anything else, then looked at them and asked, "Have you ever thought that since the clay mold casting method has so many shortcomings, why not use molds of other materials to cast them?"

"Your Majesty, the Western Barbarians used this method to cast artillery!" Li Junfeng, the craftsman, may have a lot of conversation with the emperor and also knows the emperor's temperament, so he boldly makes the speech.

When Emperor Chongzhen heard this, he stared at him and said, "What's wrong with the Western Yi using clay molds? Do you mean that other materials must not be used as molds? For example, is the iron mold casting method passed down by our ancestors? "

"Your Majesty, this is different." Li Junfeng felt that the authority was questioned and quickly explained, "Iron mold casting is indeed available, and it is convenient and has many benefits, but it is just casting small objects such as sickles and hoes. It is not possible to use it as big as a cannon!"

"Can the cannon be broken into small dots?" Emperor Chongzhen's thoughts were not bound by the times, so he immediately asked.

Li Junfeng was stunned when he heard this. He had never thought about this. It was because he had always used clay molds when he learned how to cast artillery from the Western Yi side!

The other craftsman Liang Yulin was inspiring, and his eyes lit up: "Your Majesty, maybe it's feasible!"

When Emperor Chongzhen heard this, he was very happy and said with a smile: "No, then try it out. Don't be afraid of failure! I believe that the technology is all experimental!"

At this time, Li Junfeng also came to his senses. With his years of experience, he was also surprised after thinking about it for a moment and quickly replied: "Your Majesty, it may be really feasible!"

Emperor Chongzhen laughed when he heard this and said that he couldn't help with the specific implementation. Since these experienced craftsmen said it might be possible, let them let go.

So he smiled and said, "Whoever can find a new and better way to cast artillery, I will reward you very much. Does mason Tang Binghong know? As long as it can be done, he will be your tomorrow!"

Tang Binghong was just a concrete implementer of the invention of cement, but he became a popular craftsman today. His status increased suddenly. Needless to mention money, the respect of these craftsmen just made them jealous. When he heard what the emperor said, he suddenly became energetic, as if he was injected with chicken blood.

The iron mold casting cannon method was invented by the then county magistrate Gong Zhenlin in the original history. Now, under the guidance of Emperor Chongzhen, a time traveler, although there are still some technical problems to overcome with iron mold casting cannons, these technologies are not a problem for the Chinese people.

For example, the positioning method used between the petals and sections of the iron mold can be fully referenced to the mortise and tenon positioning technology measures of ancient ceramic models and metal models. For example, the iron mold handles are divided into casting and the use of double-layer paint, which are also conventional techniques of traditional casting.

When Emperor Chongzhen left the military battle, he was of course happy. The opposite of his mood at this time was that Zheng Zhilong, a guerrilla in the coastal defense far away in Fujian, was extremely depressed at this time.

Gang, a servant who rushed back from the capital, reported to him about the situation after his life-and-death rival Li Kuiqi was escorted to the capital. Zheng Zhilong was so angry that he threw down his beloved tea set. He beat him to death, planned for many days and nights and exchanged for many benefits, but the result was this!

He was depressed when suddenly the imperial edict arrived, asking him to go to the capital immediately. This made him wonder. Before he could come up with a result, he heard from his hands and report: "Liu Jinsheng, a small banner of the Jinyiwei, is here!"
