I plant a field in the last days

Old man Chen finished smoking a cigarette, and he felt that his whole person felt like a god. Before, he looked like Lailaibaba's listlessness, but now his whole person is full of energy and spirit, so Lu Yuan and Lao Zhangren can see. Is dumbfounded.

"Ahem! Let me just say a few words! You are not good at this thing! The things on the drawings are the drawings of toys. To have lethality, it must have some stronger pushing devices, such as pneumatic valves, or more Stronger, hydraulic ejection device!" Old man Chen stroked his eyes and said.

As soon as Lu Yuan heard it, he knew why the old man said that all he had found was rubbish. It turned out that he had a better way, and it was simply hidden!

"Master Chen, keep talking!" Lu Yuan looked at Old Man Chen eagerly, waiting for his next words,

The other party thought for a while, then took out a piece of paper and pen and began to draw.

At the beginning, Lu Yuan felt that the other party was doing graffiti, but after watching for a while, he finally saw the doorway. The old man was originally a sketch of a crossbow.

The switches of the various devices and the whole quickly appeared on the paper. Lu Yuan only glanced at the doorway, and immediately stretched out his thumbs and praised him.

"Master Chen, I didn't see it, you are still a master of painting!" Lu Yuan couldn't help boasting.

Old Man Chen twitched his face and ignored him, and then said, "But if you want to build a qualified crossbow, you must require high craftsmanship. I will never allow defective products to come out of my hands. I will list one in a while. List, you go buy it, and when you find the materials, when will I start to make it for you!"

After speaking, I started to write a long list of various tools and materials on the paper.

Lu Yuan took it over and took a look, except for the high-temperature furnace, some electric sanding tools, and some pneumatic valve switches, all other Lu Yuan had them.

After the two left the old man's house, they heard the old man gnawing the watermelon before closing the door.

The furnace is easy to buy, and now there is no shortage of various tools. Many people choose to sell various things at low prices in order to buy water. The furnace that originally cost several thousand yuan, Lu Yuan only used a bottle of water. bought.

Then came steelmaking. Old man Chen’s craftsmanship had to say that there were indeed two tricks. Piles of waste steel were melted into iron in the furnace, and then poured into the mold. Then the old man put on a thick leather apron and began to strike iron.

Listening to the rhythmic sound of hammering hammers, Lu Yuan's family couldn't help but take a look.

"Xiao Yuan, what is this old man doing? Dangling, what kind of tool is this?" Dad Lu stood aside, his head stretched out and watched Old Man Chen beat a piece of iron rhythmically there.

"Hey, I won't tell you, you'll know after a while!" Lu Yuan didn't say what the old man Chen was doing, just to leave a suspense for his father.

"Smelly boy, mystery! Forget it, as long as you don't demolish the house!" After saying that, the old man also lost his interest in ironing, and turned away.

At that time, Lu Yuan didn't want to bring Old Man Chen to the house. After all, so many fruit trees in the house would be troublesome if they were exposed, but there was no more suitable place to strike iron. He could only bring him to the house.

But what Lu Yuan didn't expect was that Old Man Chen didn't feel any curiosity about his home scene, he went straight into the backyard with his glasses, and started to hit the iron when he moved out the tools. He kept mumbling about various proportions along the way. Problems, occasionally will come up with small calculations.

After a few hours of busy work, Old Man Chen finally completed the parts, and the next step was to assemble.

The assembly process was very fast, but when the first finished product came out, Old Man Chen didn't seem to be very satisfied with his work. After watching for a long time, he angrily finished the crossbow and threw it back into the stove. .

"Hey! Master Chen, what are you doing! You just finished this, why did you throw it away? I think it's pretty good!" Lu Yuan squatted on the side for a long time, his legs were numb, and he just wanted to take the crossbow. He took it to try it out, but before his hand stretched out, Old Man Chen threw the crossbow directly into the furnace. Lu Yuan was extremely annoyed.

"That's not good, it's a defective product, it doesn't meet my requirements, of course I have to recast it, you don't need to worry about me, what should I do, I will call you when I get it right!"

After talking about the old man Chen, who reinvested in the hard work of ironwork, Lu Yuan also shook his head.

Finally, a few hours later, Old Man Chen finally yelled at the front.

"Okay, things are done, you can experiment!"

Lu Yuan excitedly hugged half a watermelon and ran over, then handed the watermelon to Old Man Chen's hand and took the crossbow with joy.

The crossbow in his hand is very beautiful because it has no spray paint. The crossbow is not very big, about thirty centimeters long, twenty centimeters wide, and about ten centimeters high. The first hand can hold it.

Old man Chen also thoughtfully made more than 20 crossbow arrows. The crossbow arrows are small and exquisite, with a length of five centimeters, but the arrows are quite windy, and when they gently pull on the clothes, a hole appears in the clothes.

So Lu Yuan set up a crossbow and started aiming. The slot where the crossbow bolt was placed was quite smooth. Because Old Man Chen also specially installed a pneumatic device for the crossbow, this crossbow bolt could not only be fired with bowstrings, but also with pneumatic devices.

In order to test the accuracy and power of the crossbow, Lu Yuan specially found two cutting boards. Each cutting board was about five centimeters thick, and it was made of hardwood. There was no problem with the usual knife, axe and chop. .

So Lu Yuan placed the wooden board about 20 meters away, then took out a crossbow arrow and placed it in the arrow slot. For the first time, Lu Yuan chose to use a bowstring.

Pulling the trigger lightly, only a sound of "Bang" was heard, and the crossbow arrow flew out directly. Lu Yuan didn't even see the crossbow arrow clearly. He saw the cutting board in the distance falling to the ground. He picked up the cutting board and took a look. It hits the bullseye, and the five-centimeter-thick cutting board has been completely shot through, and the second cutting board also left a one-centimeter mark.

Lu Yuan couldn't help but confuse his tongue secretly, if it was shot on a person... I dare not imagine it!

So Lu Yuan used the pneumatic device again, followed by aiming and pulling the trigger. Lu Yuan only felt a slight recoil from the crossbow, and then saw two cutting boards stuck together in the distance and fell down.

After picking up the cutting board, he found that the two cutting boards were completely united. The crossbow arrow in the middle firmly nailed the two cutting boards together. It took Lu Yuan some strength to finally separate the cutting boards.
