Zhu Cixuan came out of the martial arts lecture hall, appeased the veterans, and rushed to the artillery factory without stopping.

To be precise, this is just a research department of the artillery factory, which is only responsible for research and trial production. The factory that is truly responsible for casting artillery is placed in Jiaozhou to facilitate the equipment of Xiao Tugeng's firearms department.

Johnson Chan waited early at the door and paced back and forth. Whenever he turned to the sunset, he would think of the days when he was abused with a cloth bag. When he turned around and was comforted by the afterglow of the sunset, he would think of the promises the crown prince gave him. As long as he could make contributions, he could promote the heavenly science and support missionary work in the Ming Dynasty... By then, the glory of God would shine on this land, and he would be able to return to the Lord's kingdom in heaven with peace of mind and enjoy eternal tranquility, holiness and glory.

In this expectation mixed with fear, he finally saw the crown prince and his guards. The dust raised high up, announcing that the crown prince had arrived. Without other ceremonial guards, he rushed over simply.

"My de Chau, please pay homage to the Crown Prince." De Chau hurriedly went up to him and held the bridle for Zhu Cilang.

Zhu Cixuan turned over and dismounted: "Why did Mr. Tang wait here? I heard that the artillery factory has made some small progress?"

"Your Highness!" Chau Wang trembled uncontrollably and shouted, "It's not just a small progress! This is the horn of another era! It is the gospel sown by the Lord on the Ming Dynasty!"

Zhu Cilang was stunned and threw the reins to the servant who came forward to greet him: "Go inside and say." He waved to Min Ziruo again and whispered: "Let Liu Ruoyu bring people here."

Min Ziruo was a little surprised and turned around and walked towards another guard. He whispered a few words. The guard turned his horse's head, whipped it up, and headed to the city again.

Zhu Cilang glanced at Tang Ruowang and read out his doubts. He just smiled and said, "Let's go in."

This village, which was shaped like a military fort, had already opened its middle gate, and welcomed Zhu Cixuan and his group into it.

The entire village is divided into workshop areas, residential areas, and research areas, just like a big cake divided into three pieces. Zhu Cilang followed Tang Ruowang into the main building of the research area, but did not enter the comfortable living room, but went straight into the underground hall.

This underground hall is more than ten feet deep underground and is brightly lit. It is a confidential room for artillery factories to store important items and prevent people from peeping and eavesdropping. Later generations thought that the Ming Dynasty people had no concept of technical patents, so they did not have the awareness of technical confidentiality. That was just a despise of the life wisdom of the ancients.

Literary and craftsmen know that confidentiality is more important than soldiers. Therefore, craftsmen will not easily reveal their skills. The firearm books compiled by literati will deliberately write Taixi's weight and measure units into the Ming Dynasty without converting data. They may also directly blur the words and only say the details. Therefore, relying on the Ming Dynasty's technical books to make cannons or make steel is no different from looking for fish in a tree.

"Please look at your highness." Johnson Chan said excitedly.

The underground hall is brightly lit, and a cannon is placed in the middle, which can be seen as a small-caliber red-clothed cannon.

Zhu Cixuan circled the cannon twice, reached out and touched the smooth cannon body, opened the tiger's mouth and compared the caliber of the cannon, and said in confusion: "What's special about this cannon?"

"Your Highness, although this cannon cannon cannon only fire four pounds of shells, it is a declaration of the arrival of a new era." Johnson Chan said excitedly: "Because it is not because of the cannon itself, but a new casting method! Your Highness, you may not believe it at all. It took only two months from the experiment to the production of this first cannon! Two months, Your Highness! And as long as there is enough materials, it can achieve the production speed of one cannon per Nissan!"

Zhu Cixuan's face was as calm as water, and he was not infected by the high-pitched and excited voice of Joey Wong. He touched the smooth cannon body again and said, "Who made it? Let him come to see me." If the cannon was tried for two months, then there must be someone else who started the experiment.

Zhu Cilang was obviously hit by Zhu Cilang's attitude. The raging fire in his heart was instantly extinguished, calming down the voice of the past, and saying in despair: "Abide by the order."

Zhu Cilang watched Tang Ruowang go upstairs and squatted down. The smell of iron and sulfur rushed into his nose. From the cannon, he could not see a stomata, a qualified cannon.

One Nissan per Fan... In this way, this mold can be reused... Iron Fan Cast Cannon?

Zhu Cixuan remembered a visit in his previous life. It seemed that a county magistrate invented the iron-casting cannon before the Opium War. He produced more than 100 artillery pieces in a month, leading the West for thirty or forty years. Because of this rare leading record, the iron-casting cannon method was artificially raised. In fact, the West took the forging route at that time and was about to start a high-tonnage water press soon, so naturally he would not return to the casting method.

However, when I went back to the time point of 1664, high-quality and high-yield iron mold casting cannons were definitely magical tools! Zhu Cixuan was excited and a little ashamed. He didn't expect such important and efficient technical means. Think about it, the materials science and casting technology before the Opium War were only weaker than now. As long as he was willing to invest, he would definitely be able to copy it.

"Min Ziruo." Zhu Cilang said softly.

"exist!"

"Send people to guard the village gate, and do not enter or exit. When Liu Ruoyu's people arrive, they will completely surround the place." Zhu Cixuan said: "Further, send someone to Pingdu to dispatch cavalry from two bureaus and let Zhou Yuji lead the team himself."

Although Min Ziruo was puzzled, he did not ask questions, but just turned around and executed.

When Tang Ruowang came down, he didn't know Min Ziruo's mission, and he was still wondering why the chief guard left alone. Behind Tang Ruowang was a young craftsman with a beard on his mouth, which was quite inconsistent with his tender baby face.

"Cao, grass, grass, grass people Xu Xie bowed to him, and greeted His Highness the Crown Prince." The craftsman knelt down and bowed, his body trembling.

"Get up and talk." Zhu Cixuan stretched out his hand and raised his palm, and smiled and said, "Did you think of this iron mold casting method?"

"Yes, oh! No! No...yes!" Xu Xie had a fight with his lips, and he had been wandering between yes and yes for a long time.

Zhu Cilang laughed and said, "Don't panic, just say a little bit."

Xu Xie remembered that the crown prince asked him to stand and talk, and quickly got up from the ground, opened his mouth slightly to stop his lips trembling, and swallowed, "Go back to your highness, Caomin is from Tieling, Liaodong, and his ancestors are craftsmen. During the Yongle period, he made great contributions to casting big bells, except for craftsmanship. However, he did not throw away his skills. Later, the Tartars broke through Tieling, and the younger family escaped into the pass and went to Shandong to join relatives. In the past few years, Shandong suffered disasters, and the craftsmen had no way to survive. Finally, Master Shen came to recruit craftsmen, and the younger one came to join. Thank Your Highness for giving a bowl of rice! Thank Your Highness for saving his life!"

Xu Xie said, and was about to kneel down again.

Zhu Cixuan raised his chin and asked the guard to support him, saying, "Did you think of this iron mold cast cannon?"

Xu Xie said: "When I go back to Your Highness, I have cast iron and bronze in my old age, and they are nothing more than gold, mud and wax. In the past, when we encountered bad iron, we often used copper and iron as molds to directly cast agricultural tools. After coming here, we saw that the mud pattern was prone to bubbles and had to clean the cannon chamber, so we thought about using the iron pattern to cast the cannon."

"Is it easy?" Zhu Cixuan was a little surprised: If there were traditional metal mold casting methods, the difficulty coefficient was not high, why have you been using mud style since the artillery? The advantages of iron style are completely irresistible!

"It's not easy," Xu Xie said: "One is that the steel used in the iron fan is good, but it didn't work at first, but later it was made by using Fan's steel. Then there are two layers of paint inside, which is used by grass and civilian..."

"Wait!" Zhu Cilang grabbed Xu Xie and said, "No need to explain this in detail, just write it into a booklet and send it to me directly."

"Your Highness..." Xu Xie looked puzzled: "The people who are not literate..."

"Lu Suyao." Zhu Cilang shouted immediately.

"I'm here." Lu Suyao hurried forward.

"I ordered the servant room to assign two secretaries to Xu Xie, and then find a talented and beautiful palace maid from the palace to be his wife." Zhu Cixuan looked at Xu Xie: "You haven't gotten married yet, are you?" Xu Xie rolled in with an Adam's apple, widening his eyes and never thought that the golden ingot that fell from the sky would hit him on the head.

Zhu Cixuan continued to instruct Lu Suyao: "Baron Xu Xieji was awarded the seventh rank of official position, and his father was named Xuanyilang and his mother was a gangster. He was rewarded with 500 taels of silver and 10 taels of gold."

Xu Xie's whole face twitched and he stood there.
