The door creaked open, the stone in Wang Ruoyan's heart fell to the ground, and the stone in Liu Sisi's heart also fell to the ground, but it was just a joy and a worry.

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

Wang Ruoyan snuggled on Jiang Ning's shoulder, not as warm as the newlyweds, but the snuggling of the old husband and wife, for a long time, Wang Ruoyan pushed Jiang Ning away: "Where do you go to my sister, we have been married for two years, she is the first time that the eldest girl has been on the sedan chair, you have snubbed others, and it will be spread out in the future, and the parents will be short, which is not good for her." ”

Jiang Ning frowned: "But you are my wife, why don't I pay it back if I don't accompany you here?" ”

Wang Ruoyan smiled and kissed Jiang Ning lightly on the forehead: "You have this heart, come in first, I am already satisfied, now that you are the head of the family, you have married a second wife, how can you spoil one person alone?" Walk fast, walk quickly......"

As he spoke, he pushed Jiang Ning out.

Jiang Ning also knew what Wang Ruoyan was thinking, after the miscarriage, it was only the tenth day, how could he leave her? Immediately hugged Wang Ruoyan and said, "I'm still here to accompany you......"

Wang Ruoyan sighed in Jiang Ning's arms and said: "Hey, Xianggong, our days are still long, you have already given me the wedding night, you must go to your sister today, is it possible to make me angry?" ”

Jiang Ning was pushed out of the door by Wang Ruoyan, turned around and closed, although she was reluctant in her heart, but Jiang Ning was already the husband of two people, how could she be so selfish?

Jiang Ning lingered in the courtyard for a long time, before he walked to Liu Sisi's door and gently pushed the door open, Liu Sisi was still sitting on the edge of the bed, and the hijab was still on his head.

Liu Sisi's hands were cold, listening to Jiang Ning's footsteps, his heart was pounding, and his hands were holding the sheets tightly, extremely nervous.

All day here, she was thinking, what would she do if Jiang Ning didn't come tonight? But think about it again, being able to be carried in by Jiang Ning in a sedan chair is already an unexpected blessing, Wang Ruoyan has only had a miscarriage for ten days today, how can he still expect Jiang Ning to come here to accompany him tonight?

But when the door next door was opened, the tension in her heart disappeared, and she tried hard to tell herself that Jiang Ning was doing the right thing.

But the tears still ran out by herself, after all, this is also her first time getting married, although her status is inferior, but her feelings for Jiang Ning are not bad at all, but if you think about it, forget it, after all, she has been married, will Jiang Ning treat her badly in the future? Or maybe Wang Ruoyan was going to pull her in and make plans again, maybe she was a little anxious and didn't know enough about Wang Ruoyan to make judgments.

Suddenly, there was a feeling of falling into a wolf's den, and I could only be slaughtered by others in the future.

At this moment, the door of her room suddenly opened, and she exclaimed, "Who? He lifted the red hijab off his head.

When he saw Jiang Ning, the tears that had not dried fell again, and he hurriedly pulled down the hijab again.

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

"Crying for what? Why are you still crying on your wedding day? Jiang Ning asked deliberately.

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

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

Liu Sisi said: "That's different, you were rich before, and now you are married, my sister has just had a miscarriage, if you don't go, you can't talk about it......"

Jiang Ning frowned: "Hey, one let me come here, and the other let me go there, I'm like a ball, kicking around." ”

"No, you can come over, Sisi is already satisfied, if you let you stay here today, I can't live with my sister, there will be a long time in the future, and there will be opportunities." Liu Sisi said: "Since I am already married to you, why not wait a day?" ”

Jiang Ning was able to come over, whether it was Wang Ruoyan who asked Jiang Ning to come over, or Jiang Ning persuaded Wang Ruoyan to come over, it has already proved her status in Jiang Ning's mind, there is no doubt about this, with this, it 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 doors of the two rooms, the two understood each other, which is a good thing, but it can't be like this, married two people, and now they are locked out of the door, can this be repaid?

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

"That's it, I'll study gunpowder...... Jiang Ning said secretly.

I went to the warehouse and looked at the black powder, and sure enough, the gunpowder used in the army was much stronger than the local one, so Jiang Ning moved a box in the yard and began to tinker with it, and gave Lu Yutong a brute gun, and there were not many projectiles left, black powder can not only improve the explosive power of the brute gun, but also improve the accuracy and range, so that you can start to study the matter of aiming.

In this era, the sight was still called Wangshan, with the scale as the ruler, and after repeated practice, you can master it proficiently, but for the study of wind speed, you can only rely on personal experience, and Wangshan is only used in the bow and crossbow, and the application in firearms has not appeared for the time being.

Another situation is the problem of continuous firing, simply put, the trigger lever pushes the striking iron backwards, and when the striking iron moves back, it compresses a metal spring in the butt (handle), and at the same time, the brake lever attached to the trigger will push the ratchet to drive the rotating chamber to rotate, which can turn the next breech chamber to the front of the barrel, and the other rotating rod is embedded in a small depression in the rotating chamber, which will stop the rotating chamber in a specific position so that it is completely lined up in a straight line with the barrel, when the trigger lever is pushed all the way back, It releases the striking iron, and the compressed spring pops the striking iron forward. The firing pin on the strike iron runs through the entire body of the gun and can hit the thundercap, which explodes, igniting the propellant, which releases a large amount of gas after burning, and the air pressure drives the warhead out of the barrel.

Now the question is how to ensure that after the first shot, how to stop the barrel lever in a specific position, the equipment requirements are very strict, and the craftsmen here can create the assault gun, then they must also be able to create such an instrument, the next step is to have more such talents.

Sure enough, craftsmen are the main factors driving scientific and technological progress, such as Watt, Edison, Tesla and others, for the progress of science and technology is almost epoch-making.

After having talents, how to retain talents, how to establish an assembly line, these things are to be considered, a not very mature idea appeared in Jiang Ning's mind, since Liu Ji wants to open a branch, and there is such a way to make money as hot pot, these talents can be arranged in the store, behind this yard is the assembly line, things are transported and circulated through goods, and there is a guarantee of food, clothing, housing and transportation, so that all the problems will be solved.

Jiang Ning tinkered for half the night, and finally upgraded the brand-new assault rifle fired with black powder, although it was only two consecutive shots, but the accuracy and range were greatly increased.

Unconsciously, the east is getting whiter, and the crescent moon and apricot rub their eyes and come out in their coats, but they are there.

I saw that Jiang Ning was still wearing last night's clothes and was boxing......

"Uncle...... Wake up so early......"

"Well, I was too busy last night, so I just didn't sleep, what are you doing in a daze? Why don't you get breakfast ready? Jiang Ning was righteous.

"O'...... Yes......" The two little girls blushed, and immediately knew what Jiang Ning meant, and ran away with a smile covering their mouths.
