Reborn in that autumn

The two of them knocked very, very seriously.

Ye Qiu didn't knock, because Ao Shijie in the space was observing the wall.

"Found it, counting from the top, it's the 15th row; counting from the side of the wall, it's the 6789th brick," said Ao Shijie in the space.

Ye Qiu turned to Li Zichen and said, "Brother Zichen, come here, I found it."

The two stopped knocking on the wall, stood up, turned to Ye Qiu and said, "How did you find it? Where is it?"

"The 15th row from the top and the 6789th brick from the wall"

After hearing what Ye Qiu said, Li Zichen and Ye Ran counted them from the top, and I counted them from the side of the wall.

Found it, the 6789th brick.

The two of them were jointly responsible for knocking down the bricks on the wall. They took out the pliers and hammer, inserted them gently into the cracks of the bricks, took out the small hammer in the bag, and struck it bit by bit. After a while, the two of them worked together to dig out the bricks. Come down with a brick.

After taking them down together, the rest is easy to take.

The two worked together to dig out three rows of bricks, and saw inside. The wooden machine was covered with firing bows. There were rows of arrows at the back that automatically rotated to the bows, just like the current assembly line operation, and then from The hole in the brick launches out.

Ye Ran used his headlight to see the huge machines inside, lined up in rows until they were out of sight.

He said in a sighing tone: "How did this ancient man's head grow so powerfully? It's so ingenious, but what is this mechanism called? How to crack it?"

What Ye Qiu repeated was actually what Ao Shijie said in the space. Ye Qiu improved it and said: "Mechanism is a representative of ancient scientific and technological civilization. We can see it no matter in production, life or military, etc." figure. Using mechanical power to control things skillfully and achieve magical effects is the contribution of the ancients to the world. And this contribution comes from their profound observation and thinking about nature. That is why the art of mechanism is so profound and mysterious .”

"Dharma begins with magic, and mechanism comes from the heart. Among various mechanical devices, the mechanism is the most critical part. It is small and secretive, but it "moves the whole body with one move" and controls the overall movement trend. It is the most important part of human beings. The supreme expression of wisdom and creativity. Today, when we use a rational eye to look at the whimsical mechanisms in ancient people's lives, we are not only looking for the mechanism itself, but also the ancient people's thoughts behind the mechanism."

"As early as more than 2000 years ago, people began to set up some active defense facilities in tombs, which not only served the purpose of shooting tomb robbers, but also served as a warning to others who would try to rob the tomb."

The crossbow appeared in a very ancient period, and the crossbow machine that can control shooting is already a relatively dexterous mechanical device.The firing principle of the crossbow is the same as that of the bow, but it shoots farther than the bow and arrow, has stronger lethality, and overcomes the weakness of limited physical strength and inability to last long when pulling the bow.

"The lethality of crossbows is so powerful that ancient people used this device when building their own tombs to shoot people who tried to enter the tomb passages."

Some crossbows have a range of more than 800 meters and a tension of more than 700 pounds.It would be difficult for such a powerful crossbow to be pulled apart by human arm strength alone. It can only be effective by using "pull-tension", that is, using a foot pedal to launch the crossbow.

"It would be difficult for such a powerful crossbow to be pulled apart by human arm strength alone. It can only be effective by using a "pull-open" method, that is, using a foot pedal to launch the crossbow."
