The clues have been seen through the launch of Hongtao. This thing is a trebuchet, and the principle is to use counterweights to store power. It's just that Wang Shi's courage is too small, and he is not big enough, and of course the counterweight is not heavy enough, and the storage is insufficient. The way to improve is simple, zoom in!

"......" Wang Shi was still not confident and looked at Hong Tao timidly.

"Look at what, if you dare to shed tears at will in the future, I will marry Wang Erxu to you as a daughter-in-law and let you starve to death! Go find someone, tear down the beams and pillars of these houses, and the officials will teach you to make real cannons! ”

Hong Tao has a lot of killer tricks to scare children, he used to be Wang Da, but now he is Wang Er. This trick proved to be very useful, Wang Shi ran with long legs, and soon gathered his soldiers of the New Army to start demolishing the temple not far from the West Gate.

"A few of you go and tell Commander Wang and Lord Huang, and ask them to find someone to tear down the beams and pillars of the nearby houses, and come together to learn how to make a cannon with your captain!"

Not only did he teach Wang Shi to be a trebuchet, Hong Tao planned to make use of the resources of the whole city. Anyway, these broken temples and palaces are useless, and it's just right to use them to help defend the city.

As for the cannonballs of the trebuchet, there are too many, the people of the whole city are running and dying, and the only few hundred people left are still taken back to Mawei City by Miao Kui, and the houses here are basically built with stones, all of them are dismantled and thrown out of the trebuchet, and it is estimated that they will not be thrown away for a month.

Does it work? It had to work, a brick on the head, and even with a helmet you would be knocked unconscious. There are so many large and small stones, it is not comfortable to throw them on anyone's head, even if you can't hit people and hit horses, it's enough to choke, you can't smash them all, and you can scare and scare people.

The soldiers of the new army, who were originally idle, immediately became a demolition team under the call of Hong Tao, and it was okay if the saw was not enough, and they could be carpenters like knives and axes. The big steel nails that hold the siege crossbow in place also have a use, along with the accessories of the box car, such as axles and so on.

Especially the bearings, which are so easy to use, fix four on the side of the main shaft of the trebuchet, and the wooden spindle will have much less resistance when it rotates again.

There were also trebuchets in ancient China, which seem to have been recorded since the Three Kingdoms period. However, trebuchets at that time were dragged by human or animal power. The explosiveness is not enough, and the range is not far.

The trebuchet in Hongtao Lane is derived from the Mongol return cannon and is called a counterweight trebuchet. It uses the principle of laborious lever to increase the distance of movement at one end of the throwing arm, so that the farther away from the center of the circle, the faster the speed, a bit like playing baseball or badminton.

In addition to bearings, Hong Tao also uses the ratchet principle on the manual winch, so that there is no need for too many people to pull and do not have to worry about the counterweight falling suddenly, and four people can operate a trebuchet more than six meters high.

Hong Tao really doesn't think it's big at this size, if there are steel fittings, this thing can at least be bigger. The longer the delivery arm and the larger the counterweight, the farther it will be thrown. Relying only on the wooden structure, the counterweight can only be more than a ton of stone, and then the trebuchet itself will have to fall apart.

"Put! …… Crash...... Alas...... "The first test launch was very unsuccessful, and the leather rope pocket at one end of the delivery arm was opened a little early, and the bricks in the pocket were not far away, and they all fell on the city, causing laughter and sighs from many onlookers."

"Look at you, just a little frustration and pouting, how can you be like a woman, go unload the steel tips and smash a little bit." Hong Tao has a thick skin, and it is okay if there are ten times more people to coax him. But Wang Shi didn't seem to follow him at this point, and he was a little embarrassed, so he was naturally reprimanded.

"Put! …… Woo...... "The remodeled steel tip tip was installed, and the second test shot began.......

This time it seemed to have succeeded, and a large stone weighing more than ten pounds was smoothly accelerated to the top of the trebuchet by the throwing arm, and was continuously pulled forward by the leather rope pocket more than two meters long.

Then one end of the leather bag suddenly fell off the tip of the steel tip, and the stone disappeared over the city wall with the sound of the wind, and only the delivery arm was still shaking back and forth, pressing the wooden frame and groaning.

"Eldest sister, how far is it?" Wang Shi first covered his mouth and stared at the direction where the stone flew away, and after several glances, he realized that he did not have a clairvoyant eye, and shouted at the top of the city tower to the king who was in charge of observation.

“…… It's only three hundred steps, and it's not far ......away from the siege crossbow," Wang Da looked at the distance scale outlined with stone powder outside the city, pouted and gave the answer, with a strong sour taste in his tone. Originally, she took the lead in squeezing the stone cannon of Wang Shilong, but now she can throw it so far, and she can't hang her face.

"Oh...... Oh...... My stone cannon has succeeded! Official, is 300 steps considered far? "Not to mention being able to throw three hundred steps, as long as you throw the moat King Ten, you will be elated.

The new army fought from afar, with rockets, siege crossbows, and steel plate crossbows, and thunderbolts and fire oil bombs in close proximity, and this kind of bulky trebuchet seemed to be of little use.

But as a child who aspires to become a master craftsman, it is still the first work, whether it is useful or not, as long as it succeeds, it must be ecstatic. The happy ones even forgot about the help of the officials, and the credit was piled on their heads.

"Not yet, after returning to Huangzhou City, draw your stone cannon into drawings and show it to the big-headed grandfather, and learn more from him, it is estimated that this thing can play at least five hundred steps." It's a pity that it's too heavy, and it can only defend the city and can't be carried with the army. But it doesn't matter, when you and the big-headed grandfather transform it, we will bring the necessary steel accessories when we go out in the future, and after we get to the place, we will cut down trees and tear down houses to assemble on site, which should also be a good long-range weapon. ”

The range of 300 steps is indeed not far, and the range is even closer if you install some more stones, but Hong Tao still sees the value from this machine. At present, it is not very suitable to become the standard equipment of the new army, but it can be available in the future.

The main thing is that this long-range weapon is too cheap to use and is cheap to manufacture. There is already a solution to the bulky problem, which is still learned from the famous Ah Wu. When he attacked Mawei City, didn't he also use local materials to create crashes and ladders, and he might as well learn from the practices of the ancients.

With the first successful example, even if the other trebuchets had models, everyone's motivation was even higher, and even Wang Da couldn't help but take her team into the inner city.

This girl is a ruthless person, and she is ruthless in everything. She was going to tear down the main hall of the city lord's mansion in the inner city, where the wood was even thicker. Since she is the eldest sister, her trebuchet must be taller than her younger siblings to be like words.

Four days later, there was almost no wood thicker than a leg in the outer city, and from looking down to crazy robbery, Wang Shi's invention became a weapon that the defenders of the four sides of the city wall wanted to have more, and more than a dozen large and small planes stood along the inner side of the city wall.

And this city was completely hollowed out, not only the tall buildings were demolished, but also the private houses, and the stones and bricks that were demolished were grabbed by the new army to the side of their defense, piled up into more than N piles of rubble, and just waited for the Western Xia army to come and greet them on the head.

Wang Da's trebuchet is the most powerful, the pedestal is composed of environmentally friendly thick columns, and the counterweight simply hangs the stone Buddha statue in the Baoguo Temple. It was estimated to weigh three or four tons, and Hong Tao was very worried about whether it would be thrown out with the delivery arm when it was launched.

As a result, thanks to the blessing of the ancient craftsmen, the wood used to build the palace is carefully selected, and the quality is good, and it is impossible to distinguish whether it is a valuable tree produced on the Qinghai-Tibet Plateau, anyway, it is very strong, and it can completely resist the weight of the Buddha statue.

But before Wang Da could test the longest range of this giant trebuchet, an accident suddenly occurred that night. The originally quiet night sky was torn apart by the sound of alarm horns in an instant, and the Xia people launched a sneak attack, and the location was the northern city guarded by the wasps.

"Don't panic yet, everyone is in place, don't run around, light the lights!" When Hong Tao came out of his military tent, he was almost knocked down by a soldier who was running north with a hornet's nest, and he howled in anger. How can this black light blind fight, so many gas lamps are equipped in vain!

After the initial panic, as the gas lamps lit up from the city walls, the soldiers of the new army finally calmed down and returned to their respective camps under the constraints of the captains and vice-captains of each team. In fact, most of the chaos was the soldiers who were resting, and the soldiers who were really on duty on the city wall were more calm.
