Zheng Haizhu's contact with firearms in his previous life was limited to military training and target shooting in college.

On that occasion, she hit the bullet in her gun very smoothly at the target of the classmate next door, ending her only experience as a high-level sniper with a score of zero.

However, the crews she worked with later were all filming costume dramas. In the local tyrant crew that burned funds, she learned some knowledge of guns and artillery in the Ming and Qing dynasties and contemporaries.

Coupled with the half-tone experience wholesale from Yan Siqi's ship, Zheng Haizhu does not seem too innocent in front of the old and young masters of the Ming Dynasty who love firearms.

It's just that she can accurately call out the "flintlock pistol" from the perspective of later generations, but after all, it is only on paper, and she doesn't know how to improve the arquebus into a flintlock pistol.

Lu Xiangsheng was very keen, and when he heard this principle, his eyes immediately lit up: "If the flint is faster than igniting the hemp rope, wouldn't the pill be able to be launched quickly?"

Zheng Haizhu nodded: "And in the same hour, there will be more firearms, right?" If the opponent is cavalry, a single gun can kill more enemies. However, it is not easy to change the mechanism, and it is even more difficult to match the gunpowder. Let's first make the combination gun and spindle cannon more brilliant, and the flintlock mechanism is also detailed, what does Xu Hanlin think?"

"That's exactly how it should be." Xu Guangqi said.

Just now, Zheng Haizhu had already pushed Zheng Zhilong and told Xu Guangqi about the situation of the Macau Franky Artillery Factory.

Xu Guangqi's surprise was expected by Zheng Haizhu. After all, in the real history, in a few years, after the Ming army suffered two fiascos in succession, it was Xu Guangqi who overrode public opinion and brought Hongyi cannons to Yuan Chonghuan, and the Ming Empire had a "Ningyuan victory".

What Zheng Haizhu is doing now is just to start the progress in advance, and ask Xu Hanlin to go to his old man's house and imagine a beautiful picture of "the cannon bombarding his mother".

"A few Master Ge, come, let's talk together."

Zheng Haizhu pulled Ge Hong and others out of the blacksmith shop, and sincerely praised the skills of these Zhenjiang craftsmen to Xu Guangqi.

Since Ge Hong came to the school, he has always felt the care of Zheng Haizhu, the female owner, and the respect of Lu Xiangsheng, a scholar, and his waist has gradually strengthened and his heart has become stronger.

At this time, Zheng Haizhu was led to a big man like Xu Guangqi, and after he was cramped for a while, he went through the technical difficulties such as whether the barrel needed inner iron and outer copper to prevent explosion.

Xu Guangqi was so wise and wise, after listening to it for a while, he muttered lightly, turned to Huang Zunsu and said, "Their rules are okay. However, this kind of cannon is much more complicated than the tiger squat cannon made by Qi Shaobao in the past, and it is not a good hand of cast iron and bronze that can take it down. If we can find the master craftsman who gave Frankie the artificial cannon from the Hao Realm, and take a closer look at it, we may be able to avoid many detours."

Huang Zunsu arched his hand: "Elder Xu. It's just that, in this way, the place has to be replaced with a more open place, and the cost of recruiting people, copper, iron, and gunpowder is more than 10,000 taels. Xia Guan thinks that this is a firearm for Daming, and the silver can't be paid by Songjiang Mansion, let alone Miss Zheng and they can't pay it themselves."

Xu Guangqi pursed his lips and thought about it, and said to Zheng Haizhu: "In another half a month, can you make a small section of copper on the outside and iron on the inside?"

Zheng Haizhu said, "Go back to Elder Xu, you can."

"Okay, the old man wrote a letter and asked Sun Yuanhua to come back and have a look. In addition, the old man is in Songjiang, so he will stay for a while and introduce you to a more important person."

……

The autumn weather is crisp, and there are more tourists boating on the Moon River.

Xu Dahua, Shaoqing of Taifu Temple, and Xu Bao, a domestic servant, were also on one of the small fairy boats.

"People are crowded, boats are crowded, and there is a greasy smell of flesh, which is very vulgar."

Xu Dahua whispered to Xu Bao in the Shaoxing dialect, but the boat boss couldn't understand it anyway.

Xu Bao is the son of the Xu Mansion, he served the young master Xu Dahua when he was a child, the young master studied hard for several years, and finally became the master in the Jinshi examination.

Seeing Xu Dahua roll his eyes, he hurriedly bowed down and echoed: "What the master said is true, the winding water is beautiful for thousands of years, the mountains are in the autumn of the year, how can a place like Shanghai be as pickled and rustic as our Lanting than elegant."

Xu Dahua made a "snort" in his nose, raised his chin, and squinted at the shadow on the boat in front of him.

Xu Bao weighed his master's thoughts, and said carefully, "What kind of self-combing girl surnamed Zheng did yesterday to make the master angry, right?"

Xu Dahua waved his hand generously: "How can you be angry with this kind of grass mustard. I just feel that since she has come out to do things, how can her temperament be so unpleasant, and she doesn't look like she has asked for her own officials."

Xu Bao nodded and said, "It's really ignorant, when I picked up the master today to see what of their firearms workshops, she went by boat, how could she take another boat by herself, she should serve the master on the boat, and make up for yesterday's mistakes."

Xu Dahua said with a smile: "Forget it, she is not singing in the Qinlou Chu Pavilion, and Xu Hanlin is not here today, she wants to come, she is afraid that lonely men and widows will be taboo in public."

Xu Bao hurriedly patted his ass: "That's her stupid. The old man has just been promoted to the official of the Taifu Temple, and even an old man like Xu Hanlin, who has nostrils facing the sky, wants to climb the family with you, this woman surnamed Zheng is smarter, she should be eager to tell the world, she has a friendship with Xu Siqing."

Half an hour later, the boat docked.

Zheng Haizhu jumped ashore first, and then reluctantly turned around to meet Xu Dahua's master and servant on the back boat.

This new Taifu Temple Shaoqing from Jingshi is the person Xu Guangqi wants her to get acquainted.

Taifu Temple, in the early Ming Dynasty, was an institution specifically responsible for horse administration.

Later, with the formation of the monetization trend of silver, local horse households and local governments began to pay silver to replace live horses.

For a time, the silver taels were piled up, and Taifu Temple had to set up a "Changying Warehouse" to store silver.

Changying Treasury had more and more silver, and by the late Ming Dynasty, it had become a central-level financial appropriation agency, just like the Hubu Tai Warehouse. Buying horses, paying soldiers, rewarding generals and foreign envoys, and even the weddings and funerals of royal vassal kings would all be paid from Chang Ying's treasury.

In the past few years, although Xu Guangqi was impeached for befriending foreigners and supporting the spread of Catholicism, he was still well-informed during the period of leisure in Beijing, and knew about the changes in the officials of various temples.

After seeing the firearms test workshop run by Zheng Haizhu and Lu Xiangsheng that day, Xu Guangqi thought of Xu Dahua, the new god of wealth.

"Miss Zheng, the official position of the Shaoqing of the Taifu Temple is now almost on the same level as that of the household servant. Xu Shaoqing and the old man are both from the south and have some contacts in Beijing. He got along well with the officials sent by the Holy Lord to the Taifu Temple."

Zheng Haizhu was originally very happy about Xu Guangqi's matchmaking and "confession", and in addition to supervising Lu Xiangsheng and the master of the Ge family to make iron and forge copper, he also asked Zheng Zhilong to prepare five hundred taels of silver tickets, ready to be given as a meeting gift.

However, after Xu Guangqi came to meet Xu Dahua yesterday, Zheng Haizhu was as disgusting as eating a fly.
