After traveling to ancient times, I relied on my husband to win

Qin Yan explained to Jiang Zhi the purpose of Lin Yecheng's visit and his plan to make a crossbow.

Jiang Zhi had a point, but considering the unpredictable nature of the battlefield, she suggested that he find more helpers to speed up the production of bows and crossbows.

Qin Yan was very grateful for his wife's understanding, and without hesitation he called Carpenter Chen and several people from the Ministry of Works to come and study the production of bows and crossbows with him.

Because some historical documents and TV dramas that Qin Yan had seen in modern times all had the shapes of bows, crossbows and sleeve arrows, the general appearance could be determined, and the details and mechanisms still needed to be carefully polished.

He studied the appearance of the crossbow, asked Carpenter Chen and others to make the crossbow shape he drew, and asked the people from the Ministry of Works to make the steel needles.

Qin Yan only had a rough idea of ​​what a crossbow looked like, and it was very similar in shape to a bow and arrow. Qin Yan simply added a crossbow arm perpendicular to the bow in the middle part based on the bow and arrow.

The crossbow arm is made to look like the mechanism of a spear, and pulling the trigger can fire the steel needle on the crossbow arrow.

Qin Yan made many kinds of bows, large and small, and tried each one. The effects varied, but they were all more powerful than ordinary bows and arrows.

The bows and arrows were made into large feather arrows, and smaller ones were made into more powerful steel needles. These were used by the soldiers who rushed to the front to shoot and kill the Jin cavalry.

Thinking that the bows and crossbows had already been made, he drew a few blueprints of simple mechanisms.

One of them is the trebuchet. Even if it is made in the capital, it cannot be transported to the border. It is faster to draw a map and go to the border to get local materials.

The emperor was also very pleased to see the bows and crossbows that Lin Yecheng brought, and said bluntly, "God bless Dongwu!"

He ordered all the carpenters and blacksmiths in the city to provide full assistance in making bows and crossbows.

After a week of preparation day and night, the results are very good. Although not everyone has one, it is still very good.

Originally, the emperor decided to let Lin Yecheng be the quartermaster to deliver the bows, crossbows and gunpowder made this time to the border military camps, but when he saw the catapult presented by Qin Yan, in order to gain greater advantages on the battlefield, the emperor asked Qin Yan to accompany him.

Qin Yan thought that his wife was about to give birth in less than two months. The fastest round trip would take half a month. By the time they reached the border, they might have to wait for the soldiers to become proficient in using bows and crossbows, and also build catapults.

Thinking that the emperor's order could not be disobeyed and that this was a matter of state, he could not refuse. However, he could not be absent when his wife gave birth to a child, so he asked the emperor for mercy.

The emperor agreed and promised him that he could come back once the catapult was completed.

Qin Yan received the order and went home to prepare. In fact, he went back mainly to comfort his pregnant wife.

Knowing that Qin Yan was going to the border, Mrs. Qin, who was still very agile, came over quickly with the help of a cane to find out what was going on.

Qin Yan comforted himself, saying that he was going to the supply department, not the battlefield. No matter where he went to help deliver the things, he would probably need to stay there for half a month before coming back.

When Mrs. Qin saw Jiang Zhi, who was just looking at Qin Yan with grievance but not saying anything, her heart, which had just been half relieved, became heavier again.

"Hey, Brother Yan, Xiaozhi is about to give birth, can you, can you make it back in time?"

Qin Yan was startled when he heard this, and turned to look at Jiang Zhi who was holding his hand. He took Jiang Zhi's hand and held it tightly, and promised: "Yes, I will definitely come back to accompany my wife. How can I let my wife be afraid alone."

Jiang Zhi couldn't control her tears. She had been very dependent on Qin Yan since she became pregnant. Qin Yan was also very worried about her and had basically always been by her side. But this time they had to separate and go to the battlefield.

Jiang Zhi was afraid. She was afraid that Qin Yan would be accidentally injured, that Qin Yan would not be able to make it back for her to give birth, and that something unexpected would happen during her delivery and she would not be able to see Qin Yan.

All the bitterness surged into Jiang Zhi's heart and she cried even harder. Qin Yan knew that his wife was worried about him, so he hugged her in his arms to comfort her.

Old Lady Qin looked at the young couple hugging each other and knew that they must have something to talk about, so she stopped being an eyesore and gave them some space.

Qin Yan hugged Jiang Zhi for a long time to comfort her, and repeatedly assured her that he would definitely come back.

Jiang Zhi lay on Qin Yan's chest and listened quietly to his strong heartbeat. "Then you'd better come back soon. If the baby is born without seeing you, he will not recognize you as his father. I won't speak for you."

Qin Yan listened to these threatening yet cute words and smiled sweetly, "Is that so? If that's the case, I'll be really sad. So, in order for the baby to see me when he comes out, I'll come back early to accompany my wife, okay? If I accompany my wife, she won't have to be afraid."

"You said that, and I'll remember it. If you dare to lie to me, you're dead. From now on, I'll tell the baby that you're a bad daddy and you bully me."

Jiang Zhi hugged Qin Yan's waist, nestled in his arms and said threatening words.

"Okay~ We all listen to our wife."

Qin Yan simply increased the strength of his arms and held Jiang Zhi tightly in his arms.

The two hugged each other, and it was not until the evening that Qin Yan packed up the clothes he was going to take away.

Jiang Zhi gave him cakes to pack, then shoes, then banknotes...

Qin Yan looked at Jiang Zhi, who looked nervous as if she was lacking everything. When she was about to get something, he picked her up and put her on the bed.

"Be good, please. I'll clean it up. How can I let you work so hard for me? Just wait here for me to clean it up."

"Ok."

Jiang Zhi was rejected, so she just watched him pack up idly. She was still reluctant to see Qin Yan leave, as they had never been separated since they came here.

Qin Yan simply packed up a few pieces of clothes and stood up to check on his wife, only to see a sad-looking wife.

Qin Yan hurriedly went up to comfort him, "Be good~ I'll be back soon, don't be sad, okay. I heard there are a lot of nice furs at the border, my husband will buy you whatever you want, okay."

"Buy some white fur and make them into gloves. You won't feel cold in winter. If you have fox fur, I'll bring it back and make it into a scarf for you."

Qin Yan was afraid that he would not be able to appease her, so he had to change the subject. Sure enough, Jiang Zhi's attention was diverted.

"There are foxes? Then can I keep a fox?"

"Well, this..." Qin Yan was a little embarrassed. He had never raised one, so he didn't know. Moreover, he believed deep down that raising these protected animals was illegal. He didn't study this either, so he really didn't understand.

Jiang Zhi didn't get an answer and her eyes were filled with tears again. Qin Yan was afraid that Jiang Zhi would cry and her eyes would be swollen when she woke up tomorrow, so he quickly agreed.

"Okay, okay, I'll buy you one then, okay?"

"Hmm~ burp~" Jiang Zhi hiccupped as she nodded.

Qin Yan laughed for a while, and then comforted the person for a while before coaxing him to sleep.

Qin Yan held Jiang Zhi in his arms and stayed awake all night.
