Similar to trebuchet, trebuchets are weapons of war that use the principle of levers to throw heavy objects out and cause great damage to enemy personnel or cities.

However, trebuchets are different from trebuchets, and those who have played Age of Empires 2 know that there is a kind of castle soldier called a giant trebuchet, which is a car when packed, and when it needs to be attacked, it will be dismantled and assembled into a tall trebuchet, its range and power are far greater than that of heavy trebuchets, but it takes more time to assemble.

The one that Lu Shuang harvested in the transport force is a giant trebuchet similar to "Age of Empires 2", which can cause huge damage to the city wall, and even the second-level city wall can't withstand the damage of the trebuchet. Although the catapult can move and shoot quickly compared to the trebuchet, the damage caused is far from the same, for example, the range of a small catapult or a medium catapult is 400 meters and 600 meters respectively, and a certain number of catapults need to bombard the city wall in turn to destroy the city wall, even if it is a first-class city wall, it takes a lot of time.

The trebuchet, on the other hand, is designed to maximize the rate at which it destroys walls, as it is to be reassembled, so there is no need to consider the effect of movement on the projection in the packed state. When it is assembled, it will have a range greater than that of a giant catapult, and it can throw multiple items at once, and the weight of the items allowed to be thrown is several times that of a small catapult.

At the same time, the height of the assembled trebuchet is as high as more than ten meters, and the thrown items and stones can generate a huge force under the acceleration of gravity, which can cause heavy damage to the city wall at once, and it is an absolute siege weapon in the era of cold weapons.

The county seat of Jiuyuan is the county seat of Wuyuan County, and it is a heavy city, that is, it can build a second-level city wall. Because it is a border city, the stone used in the city wall is not ordinary stone, generally seven or eight grade stone, but this is not something that ordinary catapults can destroy casually.

The Xianbei forces are mainly cavalry, the total number is small and not good at attacking fortified positions, if you follow the normal method, I don't know how many people have to die in battle to capture a heavy city, and the ratio of attack and defense to death is at least 1:3 or even 1:5. If you use siege vehicles, not to mention that people have a moat, Wang Zhi will definitely not be less of rocks and rocks, and it may not be able to effectively break through the city gate. And with trebuchets, the range is more than one thousand meters, and the defenders of the city cannot make an effective counterattack even according to the second-level city wall, so they can only send men and horses out of the city to destroy the trebuchet, which is what the Xianbei forces want to see the most, and it is better to fight in the field than in a tough battle.

Lu Shuang guessed that the Xianbei forces wanted to weaken Wang Zhi's power by constantly looting and harassing, and then use trebuchets to break through Jiuyuan County in one fell swoop. If Jiuyuan County is not breached, there is a heavy city here as a thorn in the flesh, and the Xianbei forces want to go deeper south, even if they can eliminate a part of the living force, they must spend a lot of troops on Jiuyuan County. And with trebuchets, the city wall of Jiuyuan County is no longer a moat, so this is one of the reasons why the Xianbei forces are reluctant to attack early, and the secret weapon has not yet arrived safely.

Lu Shuang sent a number of people, there are a total of five trebuchets here, and the rest are grain, which is of little value. Just as he was about to ask his subordinates to destroy these trebuchets, Lu Shuang suddenly remembered that he also had a space ring, which was usually to store some food and weapons, which was of little use. These trebuchets could not be removed without a special carpenter in their packed state, and their weight was so terrifying that it was impossible to transport them safely, and at this rate they would definitely be overtaken by reinforcements. But now it's different, with the space ring, as long as the space is enough, multiple items of any size can be stored with one click, without worrying about transportation.

It's just that Lu Shuang regretted a little, why didn't he buy his space ring when he traded with Hu at the beginning, the capacity of one thousand cubic meters is twice that of the space ring on his hand, and the current situation is that Lu Shuang can only install four trebuchets at most, and can't install a fifth. Although four is better than nothing, such an item is hard to come by, and it gives him the impression that he has one less trebuchet.

Trebuchet: Platinum-level prop, with a maximum range of 1500 meters, it has the terrifying power to destroy the city wall, under the third-level city wall, it greatly reduces the durability of the city wall, and the repair speed of the city wall after being hit by a boulder is reduced by 50%. When the boulder falls, it inflicts a massive impact on units within a radius of 10 meters outside the boulder, and has the power to kill a saint-level martial artist when hit head-on. The assembly and disassembly speed is slow, and it cannot be moved during the assembly process and after the assembly is completed.

Conditions of use: 1 king-level controller, 4 king-level carpenters, and no less than 100 fifth-order soldiers.

In the conditions of use, the system gives some explanations, the king-level carpenter is responsible for the assembly and disassembly of the trebuchet, and people who are not good at it may not assemble it well, and special talents are needed to do it. And the king-level controller is responsible for controlling the launch, otherwise even if the trebuchet is assembled, it will not hit people or the city wall within the effective range, which is a very embarrassing thing. As for the number of no less than 100 fifth-order soldiers, it means that a lot of manpower is required to work from assembly to launch, and it can be replaced by fewer high-level soldiers.

"The rest of the trebuchet will be destroyed for me, and it must not be left to the Xianbei people." Since there is a trebuchet that cannot be carried, the best thing to do is not to let the enemy get it.

Under the violence of the Eighth Order, not only the trebuchet was destroyed, but a large amount of grain was burned, but because the transport force was too long, half of the grain escaped.

The task was completed, Lu Shuang hurriedly left the battlefield with his subordinates, and Cheng Hui had already begun to suffer a lot of casualties in order to drag down the Xianbei cavalry. After the retreat signal was launched, under the cover of Cheng Hui and many special generals, the heavy cavalry left the battlefield in an orderly manner.

The general didn't know the situation on Lu Shuang's side, but he only knew that if he didn't give an order again, maybe all his ace troops would be left behind, because the five hundred heavy cavalry led by Lu Shuang were already on the way to converge, and the casualties would be even greater if they continued to fight. The general guessed that the trebuchet had been destroyed, and that the top priority was to preserve the strength of the ace troops so that the losses were minimized.

"Withdraw." The general ordered with a gloomy face.

Cheng Hui knew that Lu Shuang had succeeded, and the Xianbei general waved a few shots and turned around and left, he did not stop him, and ordered the soldiers to clean up the battlefield as quickly as possible, and then went to the designated meeting place.

This battle was the largest loss since the establishment of the heavy cavalry, and more than 100 people were killed, which made Lu Shuang, who knew the results of the battle, distressed for a while. The number of casualties of the Xianbei cavalry was even higher, five times that of the heavy cavalry, which also benefited from the leadership of the heavy cavalry troops in all aspects, but the combat experience was still lacking.

Lu Shuang ordered the soldiers to return with the bodies of the fallen soldiers, first, they had made sacrifices for the lord, and they died in a foreign land, and they should be buried in the land of the territory. Lu Shuang came up with the idea of imitating a monument to the people's heroes to commemorate these fallen soldiers. Second, Lu Shuang didn't want to be obtained by the Xianbei forces, after all, he didn't have the idea of wanting to make the alien race strong, although more than a hundred sets of equipment could not change the situation of the battle, but everyone understood the truth that a little bit added up.

That night, the troops who acted separately returned to the place where they rested last night, Lu Shuang learned in their report that the most casualties in this operation were still heavy cavalry, first three thousand heavy cavalry against 20,000 sixth-order cavalry, although they had the confidence to annihilate the other party in a dead battle, but they would also lose a lot of money, but fortunately, it was Lu Shuang's bodyguard who led the three thousand heavy cavalry, and he was also pretending to charge but delaying, buying time for Lu Shuang in the rear. Needless to say, Cheng Hui, who fought head-on, was the most killed, but he also gained a lot, and more than 500 sets of light armor used by the Xianbei cavalry were not bad for forming light cavalry in the future.

As for the 1,000 light cavalry that was seduced for the first time, it was a one-sided slaughter when they encountered 2,000 sixth-order cavalry, and it was not too easy for the eighth-order cavalry to beat the sixth-order cavalry, and they also went over to assist the 3,000 heavy cavalry. In addition, a group of light cavalry was sent to harass the reinforcements, but because the general Feige was late in passing the book, they retreated without encountering reinforcements, and they were the most idle.

As the supreme leader of Flying Sky City, Lu Shuang knew that every time he used troops, there would definitely be sacrifices, and in the future, after the Yellow Turban Rebellion, the sacrifices might be even greater. But if their sacrifice can be exchanged for the security and prosperity of the territory, it will be worth it. It's just that these data have become vivid life in the game, and in Lu Shuang's eyes, they have become a string of numbers, and he himself doesn't want to do this.

So in general, this gamble is right, how many Xianbei ace troops are killed, and the most important thing is to get four trebuchets, which is equivalent to a killer move, and whoever dares to drag it in front of Lu Shuang on the city wall in the future must think about this. And platinum-level items, at least only a saint-level carpenter can be manufactured, like catapults and other ordinary siege weapons, you need a king-level carpenter, in terms of quality directly a few levels higher, the requirements for talent will be heavenly.

But Lu Shuang didn't think that the Xianbei forces had the ability to make trebuchets, and the chances of getting it through other means would be greater, after all, there were probably only two people in the entire Eastern Han Dynasty who could make this siege weapon, and Xianbei was even more impossible.

Now that the Xianbei forces have lost all their catapults, they can guess with their toes that their leader is so angry that he grits his teeth at Lu Shuang, and wants to destroy him first and then quickly, so after returning home, Lu Shuang plans to repair for a few days, temporarily avoid the limelight, and let Wang Zhi deal with them. In the past few days of continuous combat, not only the soldiers and horses can't bear it, but even the durability of weapons and equipment has decreased a lot.
