"The function of the medicine room, as the name suggests, is the place where gunpowder is placed,"

Wang Kang continued: "The medicine room is a very important link. The medicine room is bulging in a lantern-covered manner, and the inner and outer diameters must be larger than the inner and outer diameters of the gun chamber."

"And the inner wall must be smooth, which is conducive to cleaning up gunpowder residues and takes less time..."

After listening to Wang Kang's explanation, several craftsmen fell into deep thought.

After a moment, Yue Shan spoke solemnly: "Young Master Kang, this thing looks simple, but it is very difficult to succeed!"

Another person echoed: "Yes, look at your drawings to indicate that this musket itself has to bear the pressure of gunpowder, and the material requirements are very high."

"The steel we have smelted and forged at present can meet the requirements, but this musket is not a straight barrel, but a shape that gradually increases when the mouth of the barrel goes to the medicine room..."

Wang Kang nodded. These craftsmen had already mentioned the point, which was indeed a relatively difficult point.

It is not difficult to make such a barrel with a mold, but it is difficult to meet the requirements and size.

After thinking about it, Wang Kang said again: "I know this is difficult. Now your focus is on this. How to overcome this difficulty!"

"Yes!" The few people responded.

"Okay, you guys are busy," Wang Kang ordered and prepared to leave.

"Young Master Kang," Yueshan spoke at this time.

"What's wrong, what else?"

Yue Shan said: "How can you have the opportunity? Can you invite a few craftsmen from Lu?"

"Craftsmen in Lu?"

"right,"

Yue Shan nodded and said, "The craftsman in Lu State is very skilled. You are all new products and exquisitely constructed. If you have famous craftsmen in Lu State, you should achieve twice the result with half the effort."

"Okay, I'll write it down."

Wang Kang said with a smile, and then left. It was rumored by the craftsmen in Lu State, so he naturally had heard of it.

Lu is a small country in the southeast of the mainland, with a relatively small population regardless of region.

However, the craftsmen in Lu are superb, and some combat equipment, such as siege cars and ladders, were invented by craftsmen in Lu...

If you have the chance, you should really invite a few people, which may bring you surprises.

Wang Kang kept this in mind, and then returned to Xinfeng County with Li Qingman...

When the city was built, there were many things that he needed to participate in and approve. When Wang Kang returned, he went into the study and started to deal with them.

After a while, a knock sounded outside the door.

"Squeak,"

The door opened, and a slender figure came in. She was slender and slender, with exquisite light makeup. Her long hair was tied up, and she looked very capable overall.

She is Tang Qingyi.

Tang Qingyi can be said to be Wang Kang's earliest team. He has followed Wang Kang since he acquired Feng Yage.

Later, she presided over the construction of the Heaven and Earth, Xiangge Lila, etc.

Now she is also managing all Wang Kang's business outside.

Wang Kang was still lowering his head and stroking something about the desk. Tang Qingyi didn't bother him and just waited like this.

She was also excited. It has been more than a month since Wang Kang left Yangzhou City and went to Xinfeng County. Although she often wrote letters, this is the first time she has seen her...

"Ah, you're here."

Wang Kang finally finished writing and raised his head.

"Young Master Kang," Tang Qingyi shouted with a little excitement.

After not seeing you for more than a month, Young Master Kang seemed to have become a little different, Tang Qingyi looked at him.

What's the difference?

It seems to be more majestic and more steady than before, but it seems to be a little dark and a little thinner...

Wang Kang smiled and said, "This outfit is indeed suitable for you."

Tang Qingyi was wearing the suit he designed before, the outfit of a white-collar beauty in his previous life.

"only……"

"Just what?" Tang Qingyi bit her lip.

"It's just that the skirt is a bit long..."

"I knew Young Master Kang, you would say that," Tang Qingyi's face turned slightly red.

The young master has indeed changed elsewhere, but the hooligan's appearance has not changed.

"Okay, sit down," Wang Kang said again.

Tang Qingyi sat down on the chair opposite Wang Kang and said, "The changes in Xinfeng County are so great. You are really amazing, Master."

"Have you been to Xinfeng County before?" Wang Kang asked curiously.

“I’ve been there once,”

Tang Qingyi smiled and said, "Although you haven't returned to Yangzhou City for a long time, your fame has not diminished at all, but it has become more and more popular."

"Everyone said I'm a prodigal son!"

Wang Kang didn't have to think about it, because he invested so much in Xinfeng County that those uninformed urban people had long been spreading.

"Not only this, I have given you a new title..." Tang Qingyi smiled and said, "Say you are a friend of women."

Wang Kang knew that this title was obtained because he sold women's products one after another.

"What do they say," Wang Kang shook his head. He had been used to it for so long.

After pausing, he asked again, "Is my mother okay?"

"Madam is very good, I just think about you tightly,"

Wang Kang nodded. His mother had already sent him a message to him, but Wang Kang never gave in.

Xinfeng County is still under construction, but it is messy everywhere. He is about to wait for the construction.

At least we have to wait for the new castle to be built and let our parents come over and give them a surprise.

"Where is Su Zhe? How about it?" Wang Kang asked again.

In the competition for fiefdom, his cousin Su Zhe was assassinated by Yang Xiuwen and pushed down the cliff. Later, Wang Kang performed acupuncture and was treated.

But at that time, he had to come to Xinfeng County, so he asked the imperial doctor Hua, the imperial doctor, to take care of him.

Tang Qingyi said, "Su Zhe knows that Young Master Kang, you are here, and he also said he wants to come and help you. I'm afraid he will come in a few days."

"I really need his help."

Wang Kang had planned to run a school in Xinfeng County and strengthen education. His cousin Su Zhe was well-read in poetry and books.

The most important thing is that he is not just reading a dead end, but his thoughts are lively, but he is the best person to be responsible for this matter.

The two chatted for a few more times and then returned to the main business. Wang Kang asked, "How is our business now?"

“Business is good!”

Tang Qingyi nodded and said, "Heaven and earth are important for money, and they have a wide reputation. Many nobles and princes from other states come here to see them."

"There are also the new products you promote, perfumes, lipsticks, etc., which are even hot-selling, and the supply is in short supply... Especially for glass mirrors, we have set sky-high prices, but there are still people who are willing to pay!"

Wang Kang also understood after hearing this. These things were all things that were not available in this era.

It is normal to cause a sensation.

Looking at Tang Qingyi and Wang Kang, he said again: "The reason why I asked you to come is that there is a very important thing to leave it to you."

"Your order." Tang Qingyi said seriously. She knew that Young Master Kang asked her to kiss her, so there must be something important.

"Before this, you can take a look at this."

Wang Kang said, putting a piece of paper in front of her.
