After Liu Yao captured Yiyu alive under Dali City and annexed the Void Army, he did not retreat despite Liu Jun's repeated suggestions.

The key is that although Liu Yao is still a Hu person in his bones, he has read and written classics since he was a child, and he has been deeply influenced by Chinese culture, and he instinctively feels that Feng Yi is fertile soil and Shangjun is wild. Although Feng Yi is broken now, as long as I continue to go south, break Chang'an, and move people over to reclaim the land, it will not take three years to be able to eat enough soldiers and be proud of the world; Shangjun is now half of Thailand grassland, and it has to be nomadic when it is defeated, and it is impossible to cultivate the land, and the nomads are easy to gather and disperse, so I am afraid that it will be difficult to compete with China in the future......

And if it were a day earlier, maybe Liu Yao would have rejected the opinions of the generals and listened to Liu Jun's advice after thinking about it repeatedly, weighing the pros and cons...... I'll ask the cheap brother-in-law if he has any good ideas.

So under the pretext of thinking carefully, he ordered the generals to retire temporarily. He turned his head, called Yang Yi, and entered the inner tent to see the sheep offering his face. Speaking of today's events, Yang Xianrong said: "The king is a hero of the world, and he cannot be compared with Sima Jianu. The concubine was born in Gaomen, and it is often said that all men in the world are as unbearable as their ex-husbands, but since the scarf, they have known that there are big husbands in the world - how can they see difficulties and think about retreating, abandon this Chinese land, and be willing to be a barbarian Tartar? ”

Liu Yao smiled and nodded, "Qingyan is yes." He turned around and asked Yang Yi: "Qing said that there is a way to break the city, are you willing to teach me?" Yang Yi was peeking at the beauty of his sister, and he listened to Liu Yao's question twice, and then he reacted, and quickly pulled out a piece of paper from his sleeve: "Chen Shicai thought of a sharp weapon, which can be used to save the moat, break the sheep and horse wall - there is a map of the cloud ladder on a different day." ”

Liu Yao took it and watched it carefully, and asked about the method of use, and couldn't help but be overjoyed: "Angel Uncle Rong helps me, and he will break Dali!" ”

——————————

Hu Yingzhong was silent for several days, which was expected—Liu Yao had to reorganize and try to digest those empty soldiers, which was by no means a matter of one or two days. Dali City did not dare to slack off, taking advantage of the Hu army did not come to attack, the Jin soldiers tried to tie the sieve basket with a long pole, and re-dredged the moat, although they failed to achieve full success, but at least the opponent's cavalry could not directly rush over.

During this period, Tao Kan also opened the secret door several times, sneaked out of the elite, and tried to sneak attack the Hu army camp. It's a pity that Liu Yao has been prepared, and Hu Yanshi in the east of the city and Liu Xian in the west of the city have learned from Liu Yue's past, and they are also very firmly defended, so that the Jin army has no gaps.

It wasn't until the seventh day that he heard the rumbling drums in Hu's camp, and Pei Gai hurriedly led the generals to the city to see, and took care of Tao Kan: "Liu Yao rests for a week...... Seven days, the first siege of the city, must be well prepared, the momentum must be overwhelming - the king must be careful, do not lose. Tao Kan bowed down to receive the order: "What Pei Gong said, Kan remembered it in his heart." ”

Immediately, I saw ten carts pushed out side by side in Hu Yingzhong, rumbling straight towards the moat. Pei Cai put his hand on the awning, watched intently, immediately turned his head, and asked Xu Yu who followed him with a smile: "What is the purpose of this car, is Ziyin likely to know?" Xu Yu also smiled: "I don't want to be in Huluzhong, there are also talents who know ordnance - this car is similar to the river crossing car I dedicated to Ming Gong the day before yesterday, so its use can be known regardless of it." ”

A few days ago, Xu Yu was inspired by Pei Gai's painting of the ladder, and drew a "Diagram of Crossing the Stream" and presented it to Pei Gai. This kind of car is seven feet wide and one zhang long, with six wheels under it, but the spokes are thick and small, that is to say, the car plate is very close to the ground - less than two feet - and there is another plate in front of the car, which is the same width as the car plate, but nearly two feet long, and is connected with the car plate with an iron ring. When usually traveling, the upper plate is turned up, and the car plate is at an acute angle of 45 degrees, can be used to shoot arrows, once encountered any deep stream, moat, you can turn the upper plate down, like a bridge on the stream.

At that time, Pei Gai saw this picture, and said with a smile: "When the army is marching, why should you use this car like a deep stream?" And there is a deep stream, the surrounding terrain must be narrow and bumpy, how to accompany this car? But...... It can be used to siege the city and seize the moat, but unfortunately it is the thieves who attack my city, not me who attack the thief city. ”

Xu Yu replied: "The function of this car is not only to cross streams and cross trenches, but also to implicate several ropes and use them as pontoons." ”

Pei Gai shook his head: "It is not easy to planing such a large plank, and because it is huge, it is difficult to transport even if it is disassembled, so it is better to find a boat to make a bridge." "It's too big a siege machine to be built temporarily, and it's impossible to take it away, so what's the chance, I spent so much time and couldn't find a ship, so I have to make you this thing?

Therefore, this picture has been put aside for the time being, who would have thought that what was seen before the battle today would be similar. As Xu Yu said: "Its use can be known without asking." "I'm here to cross our moats!

The ten carts pushed out by Hu Jun were wider than the "river crossing carts" designed by Xu Yu, and they were lined up in a line in the guards of the soldiers, but they were quite far apart from each other - probably for fear of being served by the artillery trucks. Moreover, the outside of the upper plate of this kind of car seems to be pasted with leather and hemp, which can not only shoot arrows, but even if the stone bullet is smashed head-on, there is a high chance that it will be bounced off and will not be damaged.

However, Xu Yu was a professional after all, and he quickly discovered the weakness of these vehicles: "The board is very wide and long, but it does not use four wheels, and it seems to be ordinary wheels, too thin and too high. If Hu Bing is greedy for comfort, or sits on the car to avoid arrows, he is afraid that if he applies a slight external force, the car plate or wheel axle will break...... Ming Gong can order the casting of throwing stones. ”

Pei Cai smiled and shook his head: "I have my own clever plan, just give it a try." ”

——————————

Yang Yi is not boasting out of thin air, he does have a preference for the way of machinery, and he has studied a little, so he can say after watching the defense of Dali City: It is very ingenious, but it is a pity that he can't stop me. On the same day, he presented Liu Yao with a pattern of the car crossing the trench, explained in detail, how to use it, Liu Yao was overjoyed, and immediately named it "Flying Beam Car" - the beam is the meaning of the bridge - and appointed Yang Yi as the director of the craftsman camp to supervise the construction.

It took seven days for Yang Yi to finally build ten of them - mainly because although there were many craftsmen in Huying, the level was uneven, and the management had always been negligent, so he was forced to rework several times. And according to Yang Yi's original design, the wheels had to be newly made, otherwise he was afraid that he would not be able to bear the weight of the beam car - he designed it to be able to sit on it - but he was devastated by Liu Yao, and he had no choice but to install the wheels of the grain truck.

Therefore, before the march, it was strictly ordered that except for the commander, no soldiers were allowed to board the car. But the problem is that the car is safe to look at, the arrow can't shoot, and the stone is difficult to hit - the upper plate is longer than the lower plate, and it is raised diagonally, just covering the entire body - there are still many Hu soldiers who find an opportunity to climb up. The speed of the flying beam car slowed down, and it squeaked and showed signs of falling apart......

Seeing that they were about to enter the farthest distance of the bow and arrow projectile in the city, several artillery carts in Dali City opened fire first, and the overwhelming stones of all sizes covered the Hu army's array. Most of the Hu pawns are no longer afraid of throwing stones, but they still inevitably raise their heads slowly, looking for opportunities to dodge, and the array is chaotic. Immediately, a stone the size of a pottery poppy happened to hit the upper board of a flying beam car, and the upper board shook for a while, but finally it was safe and sound, and Hu couldn't help but burst into cheers.

Liu Yao immediately twisted his beard after the battle, and smiled: "Pei Gai, let's see how you resist my 'flying beam'!" "He knows that where there is a way to siege the city, there must be a way to deal with it, but the problem is that you have to give enough time to think and prepare, my kind of car is not available in ancient books, the latest invention, unless there are spies in the camp and leak the map to Dali City in advance, otherwise for a moment or three, you can't shoot arrows or stones, and what good way can you come up with to destroy it?

Yang Yi next to him had a solemn face and reminded Liu Yao: "The king should urgently order the troops to get off, otherwise they will be destroyed before they reach the moat." "Liu Yao said yes, immediately sent an order to his cronies, saying that you should chase after you on horseback and drive the soldiers out of the car, and if you violate the order, you can kill them on the spot!

In fact, Yang Yi is not very worried, because whether Dali City can be broken or not, what does it matter to him? His main purpose was just to gain Liu Yao's appreciation, so that he could stay by his side forever - and be closer to Yang Xianrong. It's not so unlucky, the ten flying beam cars didn't get close to the moat and the board or axle broke, but as long as one of them can come in handy, Liu Yao can't blame himself - if you want to blame, blame you for not having enough qualified craftsmen in your camp.

But he knew that he had spoken too much before, so Liu Yao asked him to make equipment as soon as they met, and then urged him several times...... He also said that he wanted to design a ladder for Liu Yao, but he stayed in the craftsman camp for the past seven days, and he didn't sleep a single night, so how could he have time to paint? That's why I decided that this time I should pretend to be calm, so as to reserve enough way for myself to retreat.

Seeing that the flying beam car had passed the first round of artillery strikes, Yang Yi was secretly happy in his heart. He boasted that the flying beam car was absolutely not afraid of bows and arrows, but his strength was insufficient, and he was afraid of being smashed by a cannon. But as long as you can carry it one or two times without falling apart, that's enough, because according to Liu Yao's previous description, there are not many artillery trucks in the city - after all, in this era, that thing is too high-tech and cost--accurate is even more dangerous, how can it all be hit.

Before Liu Yao's personal troops arrived in front of the battle, he scolded Hu Bing to get out of the car, and the Feiliang car had already entered the range of the bow and crossbow in the city. I saw that dozens of arrows were shot down, only a few were nailed to the plank, and the rest all slipped off - skin, hemp, not only for stone, even for arrows have a certain defensive effect.

Seeing that the moat was in sight, Liu Yao and Yang Yi couldn't help but be happy, who would want to change the situation suddenly in an instant! A burst of fire suddenly flashed on the city, and then countless arrows with flames were projected down, and they all hit the upper board of the flying beam car - Yang Yi couldn't help but be stunned!

He just thought about repelling arrows and preventing stones, but he didn't think about fire prevention! The reason is also very simple, rockets are not commonly used in these days - because there is no suitable ignition material, so during the flight of the arrow, the flame attached to it is easily extinguished by the wind pressure - if you throw a torch, how far can you throw it? The flying beam car stopped before it reached the trench, and then turned down the upper board to build a bridge over the trench, and the inner side of the upper plate was burned to burn, and Yang Yi made fire prevention facilities on the inside - there was a water tank on the car, so that the soldiers often diverted water and splashed it wet - who would have thought that it would also be done on the outside?

Yang Yi couldn't help but say that on that day, the Wei general Hao Zhao rejected Kong Ming in Chencang, and used a rocket to break Kong Ming's ladder...... He never understood how to do it, and always felt that there must be moisture in the rumors. The ladder must be erected on the city wall, so if you throw a torch to burn it, why use rockets? If the ladder was burned with a rocket before approaching the city, what did Hao Zhao do? What exactly did he find to start a fire? Is it used in Dali City today because of Hao Zhao's secret inheritance?!
