Chapter 19 Toys
Su Liang looked at Yun Lang and said with a smile: "Not bad, horseshoe is a good thing, I heard that it was from your hand?"
Seeing that Su Liang didn't seem to like him, Yun Lang didn't understand how he offended him. When he asked him questions, he clenched his fists and said: "Diaoqi Xiaojier."
"Horseshoes aren't any kind of tricks and tricks, the benefits in the middle don't need me to say that you all understand, why do smart people who can make horseshoes jump into this muddy water?"
Yun Lang said with a smile: "Come and see, there are not many opportunities like this."
"I'm afraid you came here to take advantage of the fisherman? Boys, go back. No one here can receive the fisherman's profit. Even if there is such a benefit, you can't harvest it.
A good young man is good at training soldiers in Shanglinyuan, and it will be useful after three or five years. At this time, it is a pity to lose it. "
Su Liang left after finishing his speech, and did not pay attention to the matter of the war horse that Yun Lang was going to die. Perhaps in his view, this matter had no meaning.
Yun Lang opened the steamer and ate a meat bun. Although it was horse meat, because the green onion, garlic, pepper and star anise were put in enough, there was no leftover of the original thick earthy smell of horse meat.
Su Liang didn't help him, he still got those dead horses, because after Hu Qi stabilized his forward position, he used long iron hooks to drag the dead people exposed on the open ground, all the dead horses back. And randomly discarded in the open space and let the rain water ...
The war in the Great Han Dynasty was not as stupid as Yun Lang thought. Those Hu Qi also knew the reason of step by step. They were advancing in the rain for two consecutive days. The position constructed by ladders and shields stepped closer to the city wall. .
At this time, cavalry should be sent out of the city to destroy these advancing positions. Even if the cavalry does not come, they should send swords and shields to relieve the crisis. Once these ladders are allowed to reach the camp, those ladders that are not like ladders will become instantaneous. All roads leading to the top of Yingzhai.
I couldn't understand what Lei was trying to do. I watched people being shot by feather arrows all day long. After watching them for two days, it was boring to watch more. Yun Lang would rather stay in the camp and steam buns.
Huo went sick, Cao Xiang, Li Gan came back from the front, Yun Lang caught three hot steamed buns and threw them to them, Huo went sick, Li Gan ate very sweet, only Cao Xiang looked at the steamed buns, and he was sick ...
"What's up with him?"
"Today Lei was dispatched with a stone cannon, and it was so miserable to smash those Hu Qi. The hard-built position was also smashed by a mess of rocks.
Fortunately, we were not dispatched. The sky was full of flying boulders, and there were not enough troops to smash them. "
Huo went sick while eating steamed buns and said that from his eyes, Yun Lang could see deep fear.
Yun Lang tilted his head and glanced at the gray sky. He remembered the trebuchet. The return to the gun was supposed to be brought to the Central Plains by the Mongols after the Southern Song Dynasty. Why is it now?
Cao Xiang finally had no appetite to eat the meat buns, and regretted to put aside to drink the saliva: "Lei was actually a stone cannon in his hand?"
Hearing Cao Xiang say this, Yun Lang couldn't help but look strange.
"Looking at the scene where the sky is full of rocks, Lei was actually armed with twelve stone cannons. This time, our people have suffered a lot. Everyone who came to Crouching Tigers is basically light-hearted, In a short period of time, no one could think of carrying a heavy stone cannon.
No wonder Lei was not sent out to fight in the walled city two days ago. "
Yun Lang ate a bun casually and asked, "What kind of stone cannon?"
Huo went sick to know that Yun Lang had never seen this thing, so he squatted down, drew a huge base on the ground, and then doodled a lot of trunks on the base. There was a basket on the top of the trunk, and there were many ropes under the basket.
After finishing the painting, he pointed at the thing and said: "The stone cannon is heavy and difficult to move. It is usually used to defend the city. Once the enemy strikes, it will send one hundred and ten fighters to pull the ropes and wait for the thick bamboo pole to bend. To a certain extent, a sergeant will put stones into 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 rough bamboos on a stone cannon. The turmoil is overwhelming, and the end is terrible.
At that time, Qin general Li Xinshuai's 200,000 Qin army attacked Chu. When crossing the river, he encountered the stone cannons of the Chu people. Most of the 200,000 troops were killed and wounded by the rocks. Qin general Li Xin was also missing. "
Huo Gouyi said very seriously, Yun Lang picked up a piece of wood from the ground, held the bottom in one hand, and placed a small stone in the other hand on the top of the piece of wood, and pulled the piece of wood firmly, and then let go of the stone suddenly, the stone Hey flew away far away.
Then throw away the wood chip saying: "Just this thing?"
Li Gan dazedly forgot to eat steamed buns, Cao Xiang nodded again and again: "On this thing, it's just countless times bigger."
Yun Lang said with a smile: "It seems that we have sold new stuff in addition to selling buns."
"It's not easy to say, there is no bamboo here, and even if there is no suitable solid bamboo, although the willow can be made, but the stone cannon made of willow is not strong enough to shoot far."
Yun Lang said with a smile: "Despite asking General Su Liang, a stone cannon that is much better than Lei's stone cannon can replace his ten horses?"
Huo Qubing knows Yunlang the most, and when he can't help turning up his lips, he is happy to say: "How long will it take to get it out?"
"It's okay to get ten guns a day, mainly because we have to cut a lot of wood, which is more troublesome."
Cao Xiang shook his head and said: "Let's not tell General Su first. We will say it after our own experiments. If we accidentally say something big, with General Su's temperament, we can't eat and walk around."
Seeing that Li Gan and others were all unbelievable, Yun Lang smiled and stopped talking.
This group of young people who have not taken a hand-made lesson in elementary school knows how Yunlang once used cola cans, rubber bands, and spoons to make a powerful trebuchet, although the stones accidentally hit the teacher's face because of the flying stones. The trebuchet was confiscated, and Grandma Yun was beaten fiercely, which still did not prevent him from missing that good time.
Yunlang has not only made catapults with Coke cans, but also made cantilever catapults with a few wooden bars and wire ropes. It is the kind that is equipped with a weight on one end, then extends the cantilever, and then ties the rope to the top of the cantilever. Get another leather pocket, just press down the cantilever, put the stone in the leather pocket, and finally let go of the hand, the weight will make the extension arm swell up, and then the extension arm will drive the rope, so that the rope will be a lot in the air. In a large circle, when the pocket is raised to the highest point, the knot that binds the pocket will be pulled apart by a fixed string, and the stone will naturally fly out.
In general, the longer the extension arm, the farther the stone is thrown out.
Now that Lei is taking out even the steel ruler slingshot, Yun Lang feels it's time to show his true strength.
Relatively speaking, rubber bands are needed for cola cannon catapults. In view of the lack of this thing, the tendons of cattle and horses are not very flexible, and they require a lot of manpower to pull the lever. Yunlang still thinks that the cantilever catapult is the most economical and the most Convenience.
For a mechanical engineer, it is a shame for engineers to make such a catapult.
Although there are countless more elaborate catapults to choose from, Yunlang still insists on making the roughest one, throwing out the most advanced things at once, which is not only not good for the Han Dynasty, but also has great disadvantages.
This story is clearly illustrated by the story of pulling seedlings.
This kind of catapult naturally uses an iron shaft, and there is no such thing in a hurry. Yunlang had to unload the iron shaft on his carriage. Fortunately, the middle of the iron shaft is square, and the two ends are cast round. , Very suitable for use in catapults.
One afternoon, a rough catapult without peeling off the bark was built.
Li Gan couldn't wait to put a stone weighing 150 pounds into his leather pocket ~ EbookFREE.me ~ He wanted to see how far this trebuchet could throw this boulder.
Yunlang, a small catapult, is naturally not afraid of it. Where is the power of a finger-sized stone?
This catapult is different. One hundred and fifty kilograms of pebbles, no matter where they are dropped, is a major accident.
After everyone had hidden it, Yun Lang cut the twine on the extension arm with a knife, and after listening to a bitter creak, the heavy weight stones quickly pressed the extension arm up and extended The arm also drives the rope, and the rope rotates with stones. The extension arm seems to move slowly, but the rope on the extension arm rotates very powerfully. After an acceleration in mid-air, it is set in advance. The rope pulled away from the leather pocket, and the 150-pound pebble flew out.
Seeing the stone fly out, Huo went sick, Li Gan, Cao Xiang and a group of soldiers ran out of hiding place and cheered loudly.
The stone was thrown out into the distance, and Yunlang's sight was not less than 300 meters. The heavy stone finally fell into the woods. A pine tree with thick thighs was broken by the waist.
