The next morning, someone reported to Gao Yuan that the Mo family's younger brothers had arrived at the camp with chariots and equipment.

When Gao Yuan heard this, he was also very happy, and immediately took Yun Yao and others out of the camp to greet the Mo family's younger brothers, and came to the camp gate, led by Zhai Jin and Mo Cheng. Gao Yuan smiled: "You guys are coming so fast." ”

Seeing that Gao Yuan personally came out of the camp to greet him, Mo Cheng stepped forward to salute and said: "Wu Anjun, the military situation is urgent, and there is no room for delay, so we don't dare to delay, and we have brought all the weapons in the village, I don't know if there is a mistaken war." ”

Gao Yuan smiled: "It's too late, it's too late, the Hun army hasn't come yet!" Let's talk about it in the advanced battalion, you have worked hard all the way, take a good rest. As he spoke, he invited the Mo family brothers into the camp, asked the soldiers to arrange camp rest for them, and pulled the vehicles brought by the Mo family brothers into the camp to park. At the same time, he invited Zhai Jin and Mo Cheng to sit in the big tent.

After everyone sat down in the big tent, Mo Chengcai explained to Gao Yuan in detail that this time he had brought a total of 150 Mo family disciples, including four lightning strike cars, six arrow killing cars, eight thunderbolt cars, three crash cars, four Ruyi cars, five bed crossbows, and fifty large crossbows, one hundred small crossbows, five hundred crossbow guns, and a total of 2,000 crossbow arrows. Although this batch of vehicles did not play a decisive role, it could still strengthen the defense of the camp, so having these tanks was still very helpful to the camp. So Gao Yuan immediately ordered Zhongsun Qi to immediately come up with a plan for arranging these chariot weapons.

At this time, Mo Cheng said: "Wu Anjun was in the village yesterday to see the power of the lightning strike car, but because he had to rush back to the camp, he didn't see it, and now it's time, I don't know if Wu Anjun still wants to take a look." ”

When Gao Yuan heard this, he immediately became interested and said, "Okay, there is nothing to do now, you can assemble a lightning truck in front of the camp and project it to see." ”

Mo Cheng said with a smile: "I respect Wu Anjun's life, but there is one more thing in the future, I want to ask Wu Anjun for help." ”

Gao Yuan said: "What's the matter." ”

Mo Cheng said: "Please Wu Anjun arrange people to find some stones." ”

After hearing this, Gao Yuan couldn't help but laugh and said, "This matter is easy, I will immediately order someone to find a few hundred-pound stones." ”

Mo Chengdao: "No, it's not a few stones, we need at least two thousand catties of stones, and it would be better if we could have three thousand catties." ”

Gao Yuan was a little strange and said, "We only need to try to throw a few pieces for ourselves, what do we need so many stones for?" ”

Mo Cheng said: "Back to Wu Anjun, these stones are very important, if there are no two or three thousand catties of stones, then the lightning strike car will not be able to project stones." ”

Although Gao Yuan still didn't understand what these stones were used for, after listening to Mo Cheng's words, he thought about it, anyway, a lot of stones would be needed in the camp in the future, so he didn't refuse, and immediately ordered Ling Feng to do it. Of course, there is no shortage of stones in the mountains, and there is no shortage of animal power in the army, and it is not difficult to get to 3,000 catties of stones.

Seeing that the plateau arranged for someone to find stones, Mo Cheng was not idle, and immediately called more than 20 Mo brothers, pushed a lightning car, and came to the edge of the defense line of the camp. The generals of the plateau and the Dai army, as well as the people of the Bailing clan, also gathered around Long to watch.

Although more than 20 people did it together, they obviously went through many trainings, each with its own responsibility, not chaotic at all, after the whole cart was dismantled, first refused to put the four wheels flat on the ground, lined up into a square, and a few people carried four long strips of square wood over, fixed on the four wheels, and then others started one after another, and the other parts were fixed one by one, successively ranked, and the action was very skillful.

About half an hour later, a large trebuchet was also roughly assembled, this trebuchet was similar to other trebuchets, all of which were made of thick wood to form a door beam, and then a rough wood was used as a lever to project stones, but the height of the door beam reached two feet and five feet, and the lever was more than three feet long, so it was much larger than the ordinary trebuchet. And there is a slip on the ground that is more than two feet long, through the door beam, I don't know what it is used for.

Theoretically speaking, to be like throwing a stone far away, it is natural to enlarge the trebuchet, but after the trebuchet is enlarged, one is inconvenient to move, and the other is to need a more powerful projection power, the trebuchet is generally to use the tendon or hemp rope of the animal as the projection power, but after the trebuchet is enlarged, the torque naturally needs to be increased, but the torque is increased, and it is difficult to reset after the guide is projected, so these two problems limit the infinite scale of the trebuchet.

The Mo family's method of disassembling and assembling has solved the first problem, but I don't know how the Mo family solves the second problem?

However, after the trebuchet assembly was basically completed, Gao Yuan also saw a little bit of the doorway, and at the same time understood why Mocheng needed so many stones, and it turned out that the projection power of this trebuchet did not rely on torque, but on gravity. I saw that at one end of the projection lever, a large basket was hung, and a large winch was connected, and two or three thousand heavy stones could be loaded in the big basket, twisted with a winch, lifted from the ground, fixed with a bolt, and when projecting, the bolt was dialed out, and the large basket containing the stones fell by gravity, and the projection lever was driven to project the stones, so the more stones loaded into the large basket, the greater the gravity generated, and the farther the distance of the projection was naturally also.

And at the other end of the projection lever, there is also a rope that is nearly two zhang long, and a net-like catapult net is hung, and when the projection lever is driven by the heavy force of the big basket to do the rotation movement, it also drives the catapult net to move together and throws the stones.

The projection lever is more than three zhang long, plus the catapult net, the total length can exceed five zhang, and the sinking gravity plus such a long force arm, the projection distance is naturally greatly increased.

It took about half an hour for a trebuchet to be assembled, and now it is waiting for the stones to arrive, and the generals are looking around the assembled trebuchet, although they don't know what the performance of this trebuchet is, but seeing that it can be disassembled and assembled by a cart, it is simply the oldest deformed gold and steel, from this point of view, it is also amazing. Since they are Luo Huan and Jiang Mingxia, they are the age full of curiosity, and others are at most just around to take a look, and the two of them come to the front, feel around, and see what is going on.

After a while, I saw Ling Feng come back with five or six horses, each of which carried two large baskets, full of stones, which amounted to five or six thousand catties. Although Gao Yuan only asked Ling Feng to find more than 3,000 catties of stones to come back, Ling Feng thought that there was always a need for stones in the camp, and it was a trip anyway, so Yu Crisp would bring a little more.

Seeing that the stones were back, the disciples of the Mo family worked together again, filled the big basket with stones, then hung ropes, connected the winch, and two people on each side of the trebuchet worked together, twisted the winch, and hoisted the big basket until the highest end of the door beam, and then fixed the winch with a bolt.

At this time, Mo Cheng said: "Please Wu Anjun choose a stone to try." ”

Gao Yuan nodded, there were still a lot of stones left, Gao Yuan chose a stone with about one hundred to one hundred and twenty catties from it, and said with a smile: "That's it." ”

Two disciples of the Mo family came over, picked up the stones, and put them in the stone throwing net. and placed in the slippery sliding. Mo Cheng said: "Wu Anjun, please stay back a little bit to avoid accidental injury." ”

When everyone heard this, they all took a few steps back, and Mo Cheng said in a deep voice: "Projection." ”

A Mo family disciple immediately pulled out the latch, and the large basket full of stones immediately fell, driving the projection pole to "woo", with the door beam as the center, and rotated. After the projection pole is raised, the driven catapult also moves, and it rotates along with the projection pole.

After the big basket fell, the projection pole was also completely erected, driving the catapult to the highest point, and the stone was detached from the catapult, flying forward from the diagonal top, getting smaller and smaller, drawing a large arc, falling from the air to the ground. Judging from the visual inspection alone, the distance is not much worse, if not five hundred steps.

All the generals also looked at each other, and then immediately burst out into a burst of cheers, it seems that the Mo family really did not brag, this trebuchet is really powerful. Only Shui Xinyue's eyes showed a solemn look.

Gao Yuan said: "Go quickly, find the landing point of the stone, measure how far you have thrown, and then change it to a heavier stone to see how far you can throw it." ”

As soon as he finished speaking, Jiang Mingxia said, "Let's go, let's go find the landing point of the stone." Saying that, together with Luo Huan, he casually found two war horses, jumped on the horses, and ran in the direction where the stones landed. Ling Feng called a few soldiers with a large bundle of ropes to follow behind the two of them.

After measuring, this stone was thrown 436 kilometers away, about 600 meters away, and after the stone landed, it smashed a pit more than three feet deep in the ground, and popped forward two or three feet away, which shows that the power of this projection is indeed very amazing.

More than a dozen projections were made with stones of different weights, and the result of this trebuchet projection was that a stone weighing more than 200 catties was thrown at a distance of 385 steps, and a stone weighing about 50 or 60 catties was thrown at a distance of 507 steps. The stones weighing between 100 and 150 catties are basically stable between 400 and 450 steps. Overall, the range is more than double that of a typical trebuchet, and about a hundred paces longer than a bed crossbow.

And Gao Yuan estimated, the time required for each projection is about two to three minutes, although it is slower than the general trebuchet, but it is also completely acceptable, so whether it is the range or the frequency of projection, Gao Yuan is very satisfied, if this kind of lightning truck can be produced in large quantities, large quantities of centralized use, it can indeed play a big role on the battlefield. At the very least, the strike distance of the representative army can be greatly improved.
