Chapter 19 Toys

Su Liang glanced at Yun Lang and smiled: "It's not bad, the horseshoe is a good thing, I heard that it came from you?" ”

Yun Lang saw that Su Liang didn't seem to have a good impression of him, and didn't understand how he offended him, so when he saw him asking, he had to hug his fists and say, "Carving insect Xiaojier." ”

"The horseshoe is not a small skill of carving insects, and the benefits in the middle do not need to be said to you, you all understand, why does a smart person who can make a horsefoot have to jump into this troubled water?"

Yun Lang smiled: "Come and see, there are not many opportunities like this." ”

"I'm afraid I'm here to reap the benefits of the fisherman, right? Go back, boys, no one here can receive the benefit of the fisherman, and even if there is such a benefit, it is not something you can reap.

A good young man, just train in Shanglinyuan, and after three or five years, it will be of great use, and it is a pity to lose it at this time. ”

After Su Liang finished speaking, he left, ignoring the matter of Yun Lang's war horse that was about to die, perhaps in his opinion, this matter did not have any meaning.

Yun Lang opened the steamer and ate a meat bun, although it was horse meat, because there was enough onions, garlic, peppercorns, star anise, the original heavy earthy smell of horse meat was covered at all.

Su Liang didn't help him, he still got those dead war horses, because after Hu Qi stabilized his advancing position, he used a long iron hook to drag back all the dead people and dead horses exposed in the open space. and discarded in the open field to be watered by the rain......

The war of the Great Han Kingdom was not as stupid as Yun Lang thought, those Hu cavalry also knew the truth of step by step, and for two days in a row, they were advancing in the rain, the kind of position built with ladders and shields, and approached the city wall step by step.

At this time, the cavalry should have been sent out of the city to destroy these advancing positions, and even if the cavalry did not come, they should have sent sword and shield men to relieve the crisis, and once these ladders were allowed to reach the camp, those ladders that did not look like ladders would in an instant become a large road to the top of the camp.

I can't understand what Lei was trying to do, he watched people being shot by feather arrows all day long, and he watched it for two days in a row, and it was very boring to watch too much, Yun Lang would rather stay in the camp and steam steamed buns.

Huo Quai, Cao Xiang, Li Dare came back from the front, Yun Lang grabbed three hot meat buns and threw them to them, Huo Quai, Li Dang ate very sweet, only Cao Xiang looked at the meat buns left and right, and retched for a while......

"What's wrong with him?"

"Today, Lei was dispatched with stone artillery, and those Hu cavalry were smashed so badly, and the positions that had been built up so hard were also smashed into a mess of stones.

Fortunately, we didn't dispatch, the sky was full of boulders flying around, and no number of troops were enough to smash them. ”

Huo Quzhi said while eating steamed buns, and from his eyes, Yun Lang could see deep fear.

Yun Lang tilted his head and looked at the gray sky, he remembered the trebuchet, the return cannon should have been brought into the Central Plains by the Mongols after the Southern Song Dynasty, why is there now?

Cao Xiang finally had no appetite to eat the meat buns, and regretfully put them aside and drank saliva: "There is actually a stone cannon in the hand of Lei Fu? ”

Hearing Cao Xiang say this, Yun Lang's eyes couldn't help but become weird when he looked at him.

"Judging from the scene of the sky full of rocks, Lei was actually a twelve-tip stone cannon in his hand, this time, our people have suffered hardship, everyone came to Crouching Tiger Land is basically lightly armed, and in a short period of time, no one can think of carrying a bulky stone cannon.

No wonder Lei was not sent out of the city to fight two days ago. ”

Yun Langyou ate a bun and asked casually, "What kind of stone cannon?" ”

Huo Quzhi knew that Yun Lang had never seen this thing, so he squatted down and drew a huge base on the ground, and then scribbled a lot of tree trunks on the base, there was a basket on the top of the trunk, and a lot of ropes were scribbled under the basket.

After the painting, he pointed to the thing and said: "The stone cannon is bulky, it is not easy to move, it is generally used to defend the city, once the enemy attacks, it will send a hundred and ten wrestlers to pull these ropes, and when the thick bamboo pole is bent to a certain extent, there will be a sergeant to put stones in the basket, and then loosen the rope together, the stones in the basket will fly out to kill the enemy, at most there are twelve thick bamboos on a stone cannon, once the stone is overwhelming, the end is powerful."

At that time, the Qin general Li Xinshuai 200,000 Qin troops attacked Chu, and when he crossed the river, he encountered the stone cannons of the Chu people, and most of the 200,000 troops were killed and wounded by the stones, and the Qin general Li Xin was nowhere to be found. ”

Huo Quzhi said very solemnly, Yun Lang picked up a piece of wood from the ground, held the bottom with one hand, and put a small stone on the top of the piece with the other hand, and bent the piece of wood hard, and then let go suddenly, and the stone flew out with a bang.

Then he threw away the wood chips and said, "That's it?" ”

Li Dang forgot to eat steamed buns in a daze, and Cao Xiang nodded again and again: "Just this thing, it's just countless times bigger." ”

Yun Lang smiled: "It seems that we have sold new things besides selling buns." ”

"It's not easy to talk about, there is no bamboo here, and even if there is, you can't find a suitable solid bamboo, although the willow tree can make do, but the stone cannon made of willow is not strong enough, and it can't shoot far."

Yun Lang said with a smile: "You can go and ask General Su Liang, can a stone cannon much better than the stone cannon in Lei Shu's hand be exchanged for ten war horses?" ”

Huo Quzhi knew Yun Lang best, and when he saw that the corners of his mouth couldn't help but turn up, he said happily: "How long can I get it?" ”

"It's no problem to make ten cannons a day, but the main thing is that we have to cut a lot of wood, which is more laborious."

Cao Xiang shook his head and said: "Don't tell General Su yet, let's talk about it after our own experiments, if we accidentally talk too much, with General Su's temperament, we won't be able to eat and have to go around." ”

Yun Lang saw that Li Kang and the others all looked disbelieving, so he smiled and stopped talking.

How did this group of young people who had never taken a handicraft class in elementary school know that Yun Lang had used Coke cans, rubber bands, and spoons to make an infinitely powerful trebuchet, although because the stones flew in the face accidentally, the trebuchet was confiscated by the teacher, and he was also beaten severely by Mama Yun, which still did not prevent him from missing that good time.

Yun Lang not only used Coke cans to make trebuchets, but also used a few wooden strips and ropes to make cantilever catapults, which is the kind of counterweight at one end, and then extend the cantilever arm, and then tie the rope to the top of the cantilever arm, and then make a leather pocket on the rope, as long as the cantilever is pressed, put the stone in the leather pocket, and finally let go suddenly, the counterweight will make the extension arm rise suddenly, and the extension arm will drive the rope again, so that the rope will make a big circle in the air, and when the pocket is raised to the highest point, the slipknot that binds the pocket will be torn apart by a thin rope that is fixed, the stone will naturally fly out.

In general, the longer the extension arm, the farther the stone is thrown out.

Now that Lei was even taking out the steel ruler slingshot, Yun Lang felt that it was time to show his true strength.

Relatively speaking, the cola can trebuchet needs to use rubber bands, given that there is no such thing here, the tendon elasticity of cattle and horses is not very good, and a lot of manpower is needed to pull the lever, Yun Lang still feels that the cantilever catapult is the most economical and convenient.

For a mechanical engineer to build such a catapult is simply a shame for engineers.

Although there are countless more elaborate catapults to choose from, Yun Lang still insists on making the roughest one, and throwing out the most advanced things at once is not only not good for the Great Han Kingdom, but also very disadvantageous.

The story of pulling out the seedlings to help them grow is a clear illustration of this truth.

This kind of catapult naturally needs to use iron axles, and there is no such thing in a hurry, so Yun Lang had to unload the iron axles on his own carriage, but fortunately, the middle of the iron axle is square, and the two ends are cast round, which is very suitable for use on the catapult.

In the course of an afternoon, a rough catapult that had not even been stripped of its bark was built.

Li Dang couldn't wait to place a stone weighing one hundred and fifty pounds in his leather pocket, and he wanted to see how far this trebuchet could throw this boulder.

The little trebuchet Yunlang is naturally not afraid, no matter how powerful the finger-egg-sized stone is, how powerful can it be?

This catapult is different, one hundred and fifty pounds of pebbles, no matter where it is smashed, it is a big accident.

When everyone was hidden, Yun Lang cut the hemp rope on the extension arm with a knife, only to hear a tooth-aching creak, the heavy counterweight stone quickly pressed the extension arm, and the extension arm also drove the rope, the rope rotated with the stones, the extension arm seemed to move very slowly, but the rope on the extension arm rotated very strongly, and after a circle of acceleration in mid-air, the leather pocket was torn open by the pre-set rope, and the one hundred and fifty pound pebble flew out.

Seeing that the stone flew out, Huo Quai, Li Kang, Cao Xiang and a cadre of soldiers ran out of hiding in unison, cheering loudly.

The stone was thrown far away, Yun Lang visually measured no less than three hundred meters, and the heavy stone finally fell into the woods, and a thigh-thick pine tree was smashed by the waist, and the momentum was amazing.
