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

Wang Kang continued: "The medicine chamber is a very important part. The medicine chamber is raised like a lantern, and the inner and outer diameters are larger than the inner and outer diameters of the gun barrel."

"And the inner wall must be smooth, which will help clean up the residue and take less time..."

After listening to Wang Kang's explanation, several craftsmen were lost in thought.

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

Another person echoed: "Yes, look at your drawings, and the gun itself has to withstand a lot of pressure, and the material requirements are very high,"

"The fine steel we are currently smelting and forging can meet the requirements, but this gun is not straight, but has a shape that gradually increases from the barrel mouth to the chamber..."

Wang Kang nodded. These craftsmen have already got to the point. This is indeed a difficult point.

It is not difficult to make such a tube with a mold. What is difficult is how to meet the requirements and size.

After thinking for a while, Wang Kang said again: "I know this is difficult. Now your focus is on this, how to overcome this difficulty!"

"Yes!" Several people responded.

"Okay, you go get busy," Wang Kang ordered and prepared to leave.

"Master Kang," Yue Shan said at this time.

"What's wrong? Is there anything else?"

Yue Shandao: "If you have a chance, you can hire some Lu craftsmen!"

"Craftsmen of the State of Lu?"

"right,"

Yue Shan nodded and said: "There are many skilled craftsmen in the Lu State with superb skills. These things you have are all new products and have precise structures. If there are famous craftsmen from the Lu State, they should be able to get twice the result with half the effort."

"Okay, I've written it down."

Wang Kang said with a smile, and then left. There was a rumor about Lu craftsmen in the mainland, so he had naturally heard of it.

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

However, the craftsmen of the State of Lu are highly skilled, and some war equipment, such as siege engines, climbing ladders, etc., were invented by the craftsmen of the State of Lu...

If I have the chance, I really should invite a few of them, maybe they can bring me a surprise.

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 required his participation and approval. When Wang Kang returned, he got into his study and started to deal with them.

After a while, there was a knock on the door.

"Squeak,"

The door opened, and a slender figure walked in. She had a slender figure, delicate light makeup, her long hair was tied up, and she looked very capable overall.

She is none other than Tang Qingyi.

Tang Qingyi can be said to be Wang Kang's earliest teammate. She has followed Wang Kang since he acquired Fengya Pavilion.

After that, she presided over the construction of heaven and earth, Xiang Pavilion, Lila, etc.

Now she is taking care of all Wang Kang's business outside.

Wang Kang was still writing something with his head down, and Tang Qingyi didn't bother him, just waiting like this.

She was also excited in her heart. It had been more than a month since Wang Kang left Yangzhou City and arrived in Xinfeng County. Although they often exchanged letters, this was the first time they had seen...

"Ah, you're here."

Wang Kang finally finished writing and raised his head.

"Master Kang," Tang Qingyi shouted excitedly.

After not seeing each other for more than a month, Master Kang seemed to be a little different, Tang Qingyi looked at it.

What's the difference?

He seems to be more majestic and stable than before, but he seems a little darker and a little thinner...

Wang Kang smiled and said: "This dress really suits you."

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

"only……"

"Just what?" Tang Qingyi bit her lip.

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

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

The young master has indeed changed in other aspects, but his gangster appearance remains the same.

"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. Master, you are really amazing."

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

“Been here 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. On the contrary, it has become more and more famous."

"They say I'm a prodigal!"

Wang Kang didn't need to think about it to know that since he had invested so much in Xinfeng County, the news had long spread among the uninformed city residents.

"Not only that, I also gave you a new title..." Tang Qingyi said with a smile: "You are said to be a friend of women."

Wang Kang knew that this name came from his continuous sales of women's products.

"Let them say whatever they want," Wang Kang shook his head. He had already gotten used to it after such a long time.

After a pause, he asked again: "Is my mother okay?"

"Madam is very good, I just miss you very much,"

Wang Kang nodded. His mother had already sent him a message to come over, but Wang Kang never let her go.

Xinfeng County is still under construction, but everything is in a mess. He is ready to wait until the construction is almost done.

At least wait until the new castle is built, then let your parents come over and give them a surprise.

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

Cousin Su Zhe was assassinated by Yang Xiuwen and pushed off a cliff during the feudal competition. He was later treated by Wang Kang using acupuncture.

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

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

"I really need his help."

Wang Kang had previously planned to set up a school in Xinfeng County to strengthen education. His cousin Su Zhe read poetry and books.

The most important thing is that he is not a dead student, but a lively thinker. He is the best person to be responsible for this matter.

The two chatted for a while and then returned to business. Wang Kang asked: "How is our business now?"

"Business is good!"

Tang Qingyi nodded and said: "He has a lot of money in heaven and earth, and his reputation is very wide. Many nobles from other states come here because of his reputation."

"And the new products you promoted, such as perfumes and lipsticks, are selling like hotcakes and demand exceeds supply... Especially for glass mirrors, we have set a sky-high price, but there are still people willing to pay!"

After hearing this, Wang Kang understood clearly that these were all within his expectations, and these things were not available in this era.

It's normal to cause a sensation.

Looking at Tang Qingyi, Wang Kang said again: "The reason why I asked you to come is because I have a very important thing for you to do."

"Your orders." Tang Qingyi said calmly. She knew that Master Kang must have something important to do when he asked her to come in person.

"Before that, take a look at this."

Wang Kang said and put a piece of paper in front of her.
