Yu Yi smiled, thinking too much about himself, the ancient people may not have that concept.

Re-entering the armory shop, it was a different scene, the weapons that were put out for sale were all collected, replaced by a table, and 3 stools, Lei Chunze and his sister-in-law sat on one side, and Yuyi sat on the other side.

Or the weapon spectrum has not come to outsiders to eat for a long time, my sister-in-law has made a very hearty meal, and her cooking skills are very good, after Yuyi tried the chicken, she couldn't stop. Yuyi's appetite was greatly aroused, and he was afraid of losing his manners, so he said while eating: "Lei Chunze, you are really blessed, you are so enviable to find such a good wife." ”

After hearing Yuyi's praise, the sister-in-law blushed a little, but Lei Chunze had a manly spirit, and said: "These things should be done by women, do you want me to be a big man?" ”

After speaking, Lei Chunze asked his sister-in-law to go into the house to eat, and his masculinity was undoubtedly revealed.

Lei Chunze's behavior made the originally cheerful atmosphere drop to freezing point in an instant, and Yu Yi looked very embarrassed, if his words were placed in modern times, there would be no problem, but it was in the feudal period when women had no status.

Lei Chunze saw Yu Yi's embarrassment, and said with a smile: "You don't care about her, let's continue to talk about improving the bow and arrow, what other suggestions do you have?" ”

"Lei Chunze, at least my sister-in-law made such a table of good dishes, this has no credit and hard work, you embarrassed her in public, I can't look at it."

Yuyi and Lei Chunze have always had a good relationship, and they knew how important it was, so they expressed their dissatisfaction.

Lei Chunze smiled helplessly, and realized his problem, so he asked his sister-in-law to come out of the inner room, and then continued to talk to Yuyi.

Yuyi glanced at her sister-in-law and found that her face was full of tears, obviously wronged, she looked average, and Lei Chunze was a good match.

Yuyi knew that Lei Chunze's family affairs were not suitable to talk about anymore, so he changed the topic and answered Lei Chunze's question, saying; "I think your bow is indeed a lot better than the regular bow and arrow, but there is still a lot of room for improvement, such as the improved bow tension and the material of the arrow I mentioned earlier."

In the process of Yuyi's explanation, Lei Chunze actually put down the dishes and chopsticks in his hand, and some people who didn't understand actually moved the stool to the vicinity of Yuyi and listened carefully.

Lei Chunze's behavior made Yu Yi feel that he had gone crazy with this research, thinking of the pistol in modern society, Yu Yi thought that the bow and arrow should also achieve such automation, so he promised Lei Chunze to draw the figure after dinner.

In order not to affect Lei Chunze's eating, Yu Yi never spoke again after saying this, because he knew that as long as he was explaining, Lei Chunze would listen attentively.

Finally, Yuyi felt full, on the other hand, Lei Chunze, he was always waiting for Yuyi.

"What are you doing, these studies can't be done overnight, you can do it slowly, but if you don't eat for a long time, you won't be healthy, how can you do research when the time comes."

Yuyi criticized Lei Chunze's behavior.

Lei Chunze was about to argue, but Yu Yi interrupted directly and said, "If you don't go to eat, then I don't think there is any need to stay in the armory shop." ”

Yu Yi made a killer move, Lei Chunze had no choice but to eat as requested, after Yu Yi observed him finish eating, he came to the inner room, took out a pen and paper, and drew his ideas on paper.

Lei Chunze observed the content of Yu Yi's paintings and felt a little strange, because the content of Yu Yi's paintings was very different from the existing bows and arrows, and there were neither bows nor arrows.

Yu Yi drew a crossbow, he picked up the painting and pointed to the back of the crossbow, explaining: "This should be regarded as an improvement of the bow and arrow, replacing the bow with a mechanism." ”

Then Yuyi pointed to the middle part of the crossbow and explained: "This hole is for crossbow arrows, when you need to use it, pass the crossbow arrow through the hole, and then pull this mechanism, the crossbow will be loaded, release this mechanism, and the crossbow arrow will be launched." ”

After Yu Yi's explanation, Lei Chunze suddenly realized, he picked up the painting, patted Yu Yi's shoulder, and kept talking to himself, "This thing is good, I must make it!" ”

"The two difficulties of this crossbow, one is the configuration of the mechanism, and the other is the selection of the material of the crossbow arrow."

Yuyi added.

For Yu Yi, that is, when he was a child, he played with this kind of toy, and at that time there were children in the village, and he also asked his parents to buy one, which was particularly effective in fighting birds, and later came out with a toy gun, and the plastic bullets replaced this toy, but he still had an impression, so he could draw it completely.

After getting a new research object, Lei Chunze was overjoyed, so he took Yuyi's painting and prepared to enter the blacksmithing room to start his own research, but was stopped by Yuyi.

Yu Yi took out a knife from his body and handed it to Lei Chunze, then took another piece of paper, drew a new knife with a pen, and said, "You can help me solve the problem of this knife." ”

"The material of this knife is very special, it's a good knife, what's the problem?"

Lei Chunze took the knife and looked at it again, and then took the knife and shaved the iron sheet at hand, although the iron sheet was not cut, but there were also deep cracks, especially if it was a good knife.

So Yu Yi explained, mainly the weight and shape of the knife, the head of the knife is very light, and the handle is very heavy, which will seriously affect the hit rate of the knife as a hidden weapon, as for the material, Yu Yi doesn't understand, but he hopes to be sharper.

As a half-weapon expert, Lei Chunze naturally didn't have a problem, even if he put the knife in the iron furnace and calcined. Yuyi knew that Lei Chunze wanted to study the material of the knife in this way, so he didn't bother Lei Chunze anymore and gently retreated from the iron-striking room.

When I got to the door, I met my sister-in-law again, she should have done housework before coming out, only to see that she took out all the weapons she had put in before and put them on again.

The sister-in-law also met Yuyi and cast a grateful look, Yuyi smiled back, and then walked out of the armory shop.

Lei Chunze's marriage really surprised Yu Yi enough, thinking that he should be the first to get married among his classmates, and the other person who has the conditions to start a family should be Wu Chenggong, but this guy is now rich and rich, and ordinary women are estimated to be unable to enter the eyes of the law.

As for her sister-in-law, she gave Yu Yi the feeling that she was the image of a good girl, judging from this unpleasant eating experience, the sister-in-law is estimated to be an angry little daughter-in-law at home, without any status, but in the feudal period, such a family situation should also be very common, remembering the indignant state of the sister-in-law at that time, Yu Yi secretly laughed, the so-called following the customs, some things can not be used to, but you must keep it in your heart, you can't show it, otherwise it will look out of place.
