chance world

In the evening, the family chatted for a while and then went back to their rooms.Ding Qiyu sat at the table holding his left arm and grinned for a long time, the pain finally subsided. After working so hard for a long time, it was hard for his left arm brother who hadn't healed yet.After the pain subsided, Ding Qiyu had the energy to calm down. Although the matter of moving to the city had been put on the agenda, after all, the horoscope had not yet been written off. It was uncertain whether Aunt He's family would really come to revenge on Ding Qiyu.It happened to happen that they bullied Lian Er today, what if they came to trouble Lian Er and A Niang again while they were away?Or what if they come to the house at night to wreak havoc?These have to be guarded against.

Ding Qiyu decided to get two more pocket-sized flying arrow crossbows. It doesn't matter if there are fewer flying arrows, they are mainly for A Niang and Lian Er's emergency self-defense.There must be precautionary measures at home... Ding Qiyu took a pen to write and draw on the paper, and a preliminary sketch of a simple anti-theft mechanism was presented on the drawing.Satisfied with his idea, Ding Qiyu turned off the light and lay down on the bed, secretly thinking about the plan to produce and sell Quyeli. First of all, he must promote Quyeli in Hejia Village. Master He helped with the production, and he was paid a part of every curved leaf plow, and at the same time, he could also earn a sum of money.The core data, especially the positions and key angles of several key points on the surface of the plowshare, are still kept in my own hands, although no one in this world can understand the blueprint I drew... As for the curved leaf plow Please discuss the price with Master He before deciding.After being popularized in Hejia Village, it can also be brought to the farmers under the General's Mansion for trial use. It is best to make it famous and let the farmers around Xingcheng know about Quyeli.And all of this must hurry up, before the reed potato is planted in late autumn, take advantage of this wave of reed potato planting to promote the curved leaf plow.

Ding Qiyu made up a plan in his heart, and then he hugged his left arm brother and fell asleep.On the second day, in his free time, Ding Qiyu hurriedly made two flying arrow crossbows with a single chamber and three arrows, and gave them to each of Auntie and Lian Er, and carefully trained them on the usage methods and precautions. , asked them to carry it with them wherever they went, and try not to go out alone.At night, Ding Qiyu calculated all the data needed for the anti-theft device he had conceived, and did not fall asleep until Yinshi, which was the first time she stayed up late after coming to another world, and it was time to wake up after not sleeping for a while. With a dazed head, he said with emotion, "It's really 'Su Su Xiao Zheng, Su Ye is in the public'!" He went to the city again with dark circles on duty.

After returning from the city, Ding Qiyu went to visit Master He.When he told him about his plan about Quyeli, Master He was overjoyed and immediately agreed to make Quyeli with his newly recruited apprentice and Ding Qiyu.Ding Qiyu told Master He about the structure and materials of the parts except the plowshare. They tried several times and found that the speed of cooperation was very fast. At this speed, more than a dozen curved leaves could be driven out in one day. plow.The three discussed the selling price, and took Qu Yeli to the village entrance to beat gongs and drums to publicize. Many villagers in Hejia Village had seen the benefits of Qu Yeli the day before yesterday, and they had long been yearning for it. Within an acceptable range, how convenient it would be to plow the land after buying a handful.Even those who have never met Qu Yeli that day can still try it on the spot today.Some of the surrounding villagers were worried about the service life of the Quye plow. Ding Qiyu immediately said that the Quye plow was made of high-quality materials, and it would not be damaged no matter how much it was beaten. The clang bangs are still intact.This made the villagers more determined to buy. Ding Qiyu and the others received orders on the spot and produced according to the order quantity without any deposit. After all, the first order of business is "demand first", and most people will not order or not buy.There are more than 60 households in Hejia Village, and more than [-] households immediately ordered Quyeli, which can be said to be a good start.

But Ding Qiyu’s life of staying up late to catch up with work began. She had to go to the city during the day, so her time to make curved leaf plows was limited to evening and night. Practice makes perfect. It took half a day to make one curved-leaf plowshare, but now it can make four in an hour.She engraved a small flying feather logo on the inner corner of each plowshare, using a very special engraving technique, which can only be identified if it is very detailed, which means "produced by Ding Qiyu". It cannot be imitated.This Curved Yeli also became her first step on the road of Mechanism Master.

The sold Quye plows were well received by the villagers, word of mouth spread, they received new orders, and even villagers from Liujia Village and Fuze Village made a special trip to try and buy Quye plows.Aunt He and Lian Er watched Ding Qiyu plunge into the pile of logs every day as soon as he came home, and they felt distressed.

Today, the aunt and the others really couldn't stand it any longer, so they tried hard and soft to make Ding Qiyu put down the work at hand and have a rest.Only then did Ding Qiyu remember that the anti-theft device he had made in his busy schedule had not yet been installed at home, so he readily agreed, and immediately left the pile of wood and ran into the room.Aunt He and Lian Er were a little surprised, why are they so obedient today?Seeing her come out with another pile of wood, both of them were speechless for a while.

Ding Qiyu put the pile of wood on the ground one by one, and said cheerfully: "Don't underestimate this pile of wood, you will know the magic after I install it in a while!"

The two watched Ding Qiyu walking around in the yard. She placed all the wooden mechanisms in her hands in inconspicuous corners of the yard. The mechanisms were connected by thin metal wires. Discover.Ding Qiyu worked hard for more than half an hour, and finally finished the installation.Ding Qiyu found a sweet potato that was about to rot from the stove house, let the aunt and Lian Er enter the house, closed the door of the house and inserted the door from the inside.When Auntie and Lian Er entered the room, they found that one end of the door latch had been connected to the mechanism by Ding Qiyu, and a metal wire went around the corner and extended to the outside of the house.

"Aniang, Lian'er, open the window so that you can see the power of the anti-theft mechanism I designed." Ding Qiyu's confident voice came from outside the door.

They opened the window in the front hall of the room, and saw Ding Qiyu smiling mysteriously at them with a rotten sweet potato in his hand: "Look at it." After saying that, he aimed the sweet potato at a filament on the courtyard layout and threw it out.

The moment the sweet potato touched the silk thread, there were "cracking" sounds from many places in the courtyard, and then, a few flying arrows were shot out from the place where the sound was made, and with a few swishing sounds, the poor sweet potato had been pierced by the strong force of the flying arrows. It was so rotten that it fell to the ground in an invisible mess.

Ding Qiyu was very satisfied with the result. He turned his head and looked at the two people who hadn't recovered their senses and said with a smile, "How is it? Isn't it great?"

When the two of them reacted, they were both amazed. Aunt He said happily: "My son is really a genius!" Her tone was full of pride.Lian Er once again thought of Ding Qiyu who said that night that she wanted to become a mechanism master, and she believed more and more that A Yu's dream would definitely come true.

Only Ding Qiyu knew that behind the "genius" that A Niang called was the precipitation and accumulation of her many years of hard work.

Ding Qiyu explained the use of this anti-theft device to the two.She put up two layers of "defense lines" around the courtyard. The defense lines are made of very thin metal wires that are not easy to break. Usually, the metal wires are loose and hang down on the ground. Because the wires are extremely thin, they will not affect normal activities. The door of the door will not be tightened until it is bolted from the inside, and the two ends of each piece of filament are connected to the modified flying arrow crossbow.This kind of flying arrow crossbow will make a loud "cracking" sound when firing the flying arrows, which acts as an alarm.If someone breaks into the yard, the possibility of not touching the filament is very small under the two layers of defense. As long as one part of the filament is bent by an external force, the flying arrows on both sides of the filament will be bent due to the bending of the filament. It is driven to turn a certain angle, aim at the curved position, and at the same time automatically launch the flying arrow.The turning angle of the flying arrow crossbow driven by the filaments was precisely calculated by Ding Qiyu. Looking at the fate of the rotten sweet potato just now, we know that her calculation is very accurate.

Originally, Ding Qiyu wanted to use a slingshot, but then he thought about it, the villagers of the He family are simple and honest, and robberies rarely happen. If someone really breaks into the yard at night, it may not be for the simple purpose of stealing.And if the slingshot is hit, it may not be able to catch the thief. If it is replaced with a flying arrow crossbow, it can ensure that the thief cannot escape quickly under the pain of several consecutive arrows.The positions of the flying arrow crossbow and the filaments are set relatively low. Although it can make the person who gets hit suffer a lot, it will not cause permanent damage.And this mechanism will only work when the door of the house is bolted from the inside. Ding Qiyu and his family will only lock the door of the house after they all return to the house at night. There is no need to worry that this mechanism will hurt their own family.

After finishing this set of mechanisms, Ding Qiyu was much more assured of the safety of his family. I hope that Aunt He's family is bullying and fearful. It is best to believe his threat and stop causing trouble.Seeing that Ding Qiyu said that he had rested well, and plunged into the original pile of wood again, Auntie and Lian'er couldn't do anything about her.

In just a few days, Qu Yeli made a name for himself in Hejia Village and several nearby villages. Ding Qiyu browsed through his inspection roster, and it was time to "walk around" the farmlands of the General's Mansion around Xingcheng. Ding Qiyu specially brought Qu Yeli into the city.Hejia Village is in the southern suburbs of Xingcheng, and most of the farmland in the General’s Mansion is located in the northeast of Xingcheng. Ding Qiyu searched a large area of ​​farmland and found that these farmers used cattle at a higher rate than Hejia Village. After questioning, he learned that the cattle belonged to General The government rewards farmers with outstanding harvests. Under the reward mechanism, farmers here are very enthusiastic about farming, but farmers who do not use cattle are still the mainstream.While thinking about how to improve and widen the curved leaf plow, Ding Qiyu turned it into an advanced version of the curved leaf plow that is suitable for oxen and can cultivate a wide field in one circle. At the same time, he called farmers' representatives and introduced the curved leaf plow to them. .
