The door creaked open, and the stone in Wang Ruoyan's heart fell to the ground. The stone in Liu Sisi's heart also fell to the ground, but one was happy and the other was worried.

Jiang Ning lifted Wang Ruoyan's hijab and sat next to Wang Ruoyan.

Wang Ruoyan snuggled on Jiang Ning's shoulder, not as enthusiastically as a newlywed couple, but as an old couple. After a long time, Wang Ruoyan pushed Jiang Ning away: "You go to my sister, we have been married for two years, she is a big girl.

The first time you walked in the sedan chair, you gave her a cold shoulder. In the future, word will spread that the family is short-tempered and will treat her badly."

Jiang Ning frowned: "But you are my real wife, what if I'm not here to accompany you?"

Wang Ruoyan smiled and kissed Jiang Ning's forehead gently: "If you have this heart, come in first. I am already satisfied. Now you are the head of the family. You have married two wives, how can you pamper only one person? Let's go quickly.

Go quickly..."

With that said, he pushed Jiang Ning away.

Jiang Ning also knew what Wang Ruoyan was thinking. It was only the tenth day after the miscarriage. How could he leave her? He immediately hugged Wang Ruoyan and said, "I'll stay here with you..."

Wang Ruoyan sighed in Jiang Ning's arms and said: "Hey, sir, our days are still long. You have already given me your wedding night. You must go to your sister today. Are you trying to make me angry?"

These words were very serious. Jiang Ning was pushed out of the room by Wang Ruoyan and turned around to close it. Although she was reluctant to let go, Jiang Ning was already the husband of two people. How could she be so selfish?

Jiang Ning wandered in the courtyard for a long time, and then walked to Liu Sisi's door and gently opened the door. Liu Sisi was still sitting by the bed, with the hijab still covering her head.

Liu Sisi's hands were cold. Listening to Jiang Ning's footsteps, her heart was beating fast. She held the sheets tightly with her hands, feeling extremely nervous.

The whole day here, she was thinking about what she would do if Jiang Ning didn't come tonight. But she also thought about it, being able to be carried in by Jiang Ning in an eight-carriage sedan was an unexpected blessing. Wang Ruoyan had a miscarriage until today.

On the 10th, how could he expect Jiang Ning to come here to accompany him tonight?

But when the door next door was opened, the nervousness in her heart disappeared. She tried hard to tell herself that Jiang Ning did the right thing.

But she still ran away with tears in dissatisfaction. After all, this was her first time getting married. Although her status was inferior, her feelings for Jiang Ning were not bad at all. But after thinking about it, she decided to forget it.

After all, she is married, will Jiang Ning treat her badly in the future? Or maybe Wang Ruoyan was going to drag her in before making plans, maybe she was a little anxious, and made rash judgments because she didn't know Wang Ruoyan well enough.

Suddenly, I felt like I had fallen into a wolf's den and would have no choice but to be slaughtered by others.

At this moment, her door suddenly opened, and she was so frightened that she exclaimed: "Who?" and lifted the red hijab on her head.

When he saw Jiang Ning, the tears that had not yet dried began to fall again, and he hurriedly pulled down the hijab.

Jiang Ning closed the door, stepped forward and opened his hijab, and carefully looked at Liu Sisi, who was like a fairy.

"Why are you crying? Why are you crying on your wedding day?" Jiang Ning asked deliberately.

Liu Sisi wiped her tears, but pushed Jiang Ning: "If you don't go to accompany your sister, what are you doing here?"

Jiang Ning held Liu Sisi's hand, squatted in front of him and said with a smile: "Of course I'm here to accompany you. Isn't it also your wedding today?"

Liu Sisi said: "That's different. You were the one to get married before, but now you are the one to marry. My sister has just had a miscarriage. If you don't go, you can't explain it..."

Jiang Ning frowned: "Hey, one asked me to come here and the other asked me to go there. I'm like a ball, kicking it back and forth."

"No, you can come here. Sisi is already satisfied. If I let you stay here today, I would be sorry for my sister. The days will be long and there will be plenty of opportunities." Liu Sisi said, "Since I have married you,

Why not wait a day?”

Jiang Ning's ability to come over, whether Wang Ruoyan asked Jiang Ning to come or Jiang Ning persuaded Wang Ruoyan to come, has proven her status in Jiang Ning's mind. There is no doubt about this. This is enough.

After Jiang Ning was kissed by Liu Sisi again, he pushed him out of the door.

Under the moonlight, Jiang Ning walked back and forth in front of the two houses. It was a good thing that the two understood each other, but it couldn't be like this. He married two people and now he was locked out. How could he pay back if the news got out?

have to?

But neither of these two people agreed to let him in.

"That's all, I'd better study gunpowder..." Jiang Ning said secretly.

He went to the warehouse and looked at the black powder. Sure enough, the gunpowder used in the army was much stronger than the local gunpowder. Jiang Ning moved a box in the yard and started tinkering with it. He gave Lu Yutong a handful of the musket and the remaining pellets.

Not much more. Black powder can not only increase the explosive power of the musket, but also improve the accuracy and range. In this way, you can start studying the aiming.

In this era, the sight was still called Wangshan. It used the scale as a ruler and could be mastered after repeated practice. However, the study of wind speed could only rely on personal experience, and Wangshan was only used on bows and crossbows.

, its application in firearms has not yet appeared.

Another situation is the problem of continuous firing. Simply put, the trigger rod pushes the hammer backward. When the hammer moves backward, it will compress a metal spring in the butt (gun handle). At the same time, the brake attached to the trigger

The rotating rod will push the ratchet to rotate the rotating chamber, which can turn the next breech chamber to the front of the barrel. Another rotating rod is embedded in a small depression on the rotating chamber, which will

Stop the rotating chamber in a specific position so that it is perfectly aligned with the barrel. When the trigger lever is pushed all the way back, it releases the hammer and the compressed spring pops the hammer forward.

The firing pin penetrates the entire gun body and can hit the thunder cap. When the thunder cap explodes, it will ignite the propellant. After the propellant burns, it will release a large amount of gas, and the air pressure will drive the warhead to fly out of the barrel.

The problem now is how to ensure that the rotating rod of the cartridge stops at a specific position after the first round is fired. The requirements for the equipment are very strict, and if the craftsmen here can build a burst gun, they must also be able to build it.

To produce such an instrument, the next step is to have more such talents.

Sure enough, craftsman talents are the main factor in promoting scientific and technological progress. For example, Watt, Edison, Tesla and others are almost epoch-making in the progress of science and technology.

After having talents, how to retain talents and how to establish assembly lines are all things that need to be considered. An immature idea appeared in Jiang Ning's mind. Since Liu Ji is going to open a branch, there is a profitable place like hot pot.

The best way is to arrange these talents in the store. Behind the yard is the assembly line, where things are transported and circulated through goods, and the basic necessities of food, clothing, housing and transportation are guaranteed. In this way, all problems will be solved.

Jiang Ning tinkered for half the night, and finally upgraded the brand-new burst gun fired with black powder. Although it only had two bursts, the accuracy and range were greatly increased.

Unknowingly, the east became whiter, Yue Ya and Xing'er rubbed their eyes and came out with their coats on, but they were stunned there.

I saw Jiang Ning still wearing the clothes from last night and boxing...

"Uncle... you get up so early..."

"Well, I was too busy last night, so I just didn't sleep. What are you doing standing around? Why don't you go prepare breakfast quickly?" Jiang Ning spoke righteously.
