The black clouds are squeezing the city and are about to destroy it.

After two years of running-in training, the 160,000 troops stationed in He/Bei no longer have the distinction between the imperial army and the surrendered army. They only have one common name, that is, the Han army.

The black troops took neat steps from far to near. Every time they took a step, it seemed as if the heaven and earth were shaking. Further away, giant catapults up to five feet high were pushed towards Yecheng under the guidance of a large group of strong men, like a large group of monsters who chose people to eat.

In the future, there are also wells, city-breaking crossbows, and city-storming hammers. Whether veterans or new recruits, they probably saw such heavy weapons of this size for the first time in their lives. The siege weapons of the Han Dynasty in the past are like the difference between a child who has not yet grown up and a strong man.

However, his exaggerated body shape made the soldiers guarding the city feel inexplicably depressed.

The military formation stopped at 300 steps away from Yecheng. The Han soldiers divided into square formations and formed formations in front of Yecheng. This time, no one came to call the formation. After the Han army had arranged the formation, they began to push the siege weapons in the rear to the front line, dismantled the wooden wheel, fixed the brackets, and debugged the angle.

Yuan Shao stood at the highest point of the city tower surrounded by a group of civil and military personnel, looking down at the opponent's military formation and watching the siege weapons up close. He felt even more shocked. Under the huge siege weapons, humans were as small as ants. A group of generals wearing soft armor gathered in front of a catapult cart, pointing in the direction of the city wall, and holding various strange-shaped things in his hands to measure them.

"What are they doing?" Yuan Shao frowned slightly, looked at the left and right in confusion, and tried his best to drive everyone away from the attention of the giant catapult. Just look at it, it was almost level with the wall of Yecheng. You know, since Yuan Shao settled in Yecheng, this Yecheng has been expanded several times, but it was built at the level of the capital. If it were an ordinary city, facing such catapults, the city wall would probably not be as high as the catapults.

When Shen Pei and others heard this, they looked at each other in a daze and didn't quite understand.

"Cruff~" amid the sour wood friction, but a catapult suddenly made a muffled sound. The huge lever was removed with the rope and arched slightly in the air. With a low roar, as the huge rock fell in front of him, a stone bullet roared towards the city wall in everyone's astonishment eyes.

This catapult car can actually shoot a range of 300 steps!?

On the city wall, Yuan Shao and his generals watched incrediblely as the millstone-sized stone bullet smashed down with the momentum of destroying the world, and stomped on a city wall.

"Boom~"

The entire city wall seemed to be shaking. Yuan Shao held the female wall and looked at the smashed city wall in shock. A gap of more than one meter was smashed by a huge millstone. The gravel splashed out, which knocked more than a dozen soldiers around him overturned the horses. Many people died on the spot. Even those who survived by chance were seriously injured and fell to the ground and screamed.

Fear spread across the city wall like a plague. Although the damage caused by this stone bomb is not high, it is a terrifying blow to the already not-high morale.

Yuan Shao and a group of civil and military officials looked at this scene in horror. How could they fight this battle? The dozen or soccer casters placed a round of stone bullets at the city wall, and the entire city wall might not have even a complete female wall.

In the horrified eyes of everyone, the catapult seemed to have been calibrated, and the officers below were not satisfied. They ordered people to start pushing the winch and moving the catapult's position. More than a dozen Lis pulled the rope and pulled down the grooves that filled the stone bullets, adding another stone bullet.

"Cruff~Crack~"

This time, the imagined bombardment did not appear. In the astonishing eyes of the soldiers on both sides, with the boulder falling to the ground, the lever that maintained both ends broke directly from the middle, and one end of which was filled with the stone bullet roared down, smashing several strongmen who could not dodge into meat paste.

On the city wall, everyone, including Yuan Shao, breathed a sigh of relief when they saw this.

In the Han army formation, Liu Xie frowned and looked at the scene.

"Your Majesty, I deserve to die!" A master of the Ministry of Works brought more than a dozen new students to the Ministry of Works to Liu Xie and said to himself.

"Why is this happening?" Guo Jia frowned and looked at several students from the Ministry of Works. This catapult was created based on the precise calculations of these newly joined the Ministry of Works.

"Sir, this..." a student smiled bitterly: "By calculations, there should be no problem."

"Your Majesty." The master craftsman said with a wry smile: "It's not because you guys have calculated the wrong thing, but because this wood cannot support such a large amount of weight."

"Forget it." Liu Xie looked at the catapult cart that had become a pile of scrap wood, and shook his head and said, "Manpower is poor, and material resources are the same. It is not that you have calculated it wrong, but that you have never considered the strength of the wood, which is obviously not enough to support such a great force. I asked you to study in the Ministry of Works to hope that what you have learned in the academy can be applied. Don't look down on these masters of my life. They may not know much about you, but they have much more experience and knowledge than you."

"This..." A group of students thought about it carefully. As the master said, they had taken into consideration everything, but they had never considered the load-bearing ability of the wood.

"We are so proud of our superiority that we have broken the military opportunity. I hope Master Lu will forgive me." A group of students bowed to the master craftsman and said.

"No wonder you guys." Master Lu waved his hand quickly and said, "If the project was not too urgent and there was no time to test it, there wouldn't be such a thing."

This catapult was forged urgently and had not been tested.

Liu Xie nodded, looked at the direction of the city wall, and smiled and said, "Then try the city-breaking crossbow. Don't tell me that after studying in the Ministry of Works for so long, I can't even make a useful thing."

"Here!" After hearing this, several students bowed and quickly turned around and left.

"Your Majesty, I'm blunt, no one has ever thought of making this catapult cart before, but it has failed. The reason lies in the load-bearing ability of the wood." Master Lu bowed to Liu Xie with a wry smile.

Liu Xie nodded and glanced at the row of stone-catted lanes: "Removing these catapults first. Since they cannot be used, don't waste those materials. Also, the bodies of those strong men should be kept and buried."

In this purely human power era, industrial progress is sometimes made up for human lives. Even if Liu Xie has advanced knowledge, he can't do anything about this. In addition to some insights in mechanics, he may not be better than these students. From the human power era to the mechanical era, the road is still long. He also wants to see what kind of era will develop in if he continues to develop little by little according to ancient Chinese studies. It's a pity that he may not be able to live that day.

On the top of the city, Yuan Shao and a group of civil and military officials were glad to watch the catapults being returned, and they breathed a sigh of relief in their hearts. If the catapults were really bombarded like this, the court would not have to attack the city at all, and would have collapsed the city wall.

But the morale on the city wall did not improve. Although the Han army did not attack the city, the feeling of waiting, especially when in a weak situation, was like suffering, and gave people the feeling of waiting for death.

The catapult cart was pushed down, the Han army was in a row, and a group of strange-style frames were pulled in front of the formation by war horses.

carriage?

It doesn't look like it, without a carriage, two huge five-foot-high wheels rolling, and the thing in the middle looks a bit like a bed crossbow!

Thinking of the crossbow, Yuan Shao and many soldiers who participated in the battle at Hulao Pass couldn't help but think of the twenty crossbow machines that could shoot out huge crossbow arrows in Hulao Pass back then. That was not a pleasant memory. This thing was not a new crossbow machine developed by the court, right?

Thinking of this possibility, Yuan Shao and others felt a toothache. Yuan Shao really wanted to go to the court's Ministry of Works in person. In the eyes of everyone, it was just a place like a craftsman with concentrated craftsmen. The changes he has brought to the world over the years are really great, from military to people's livelihood, and even changed the previous form of war.

Those strange cars stopped when they were pulled to a distance of 200 steps from the city wall. It seemed that the range of this thing was not as terrifying as the previous catapult car, but the problem was... 200 steps and 300 steps were actually no difference for Yuan Jun. They could not even reach the bow and arrow, so they could only watch the opponent attack.

Amid the nervous eyes of everyone, the war horses were untied one by one and pulled into the back formation. Immediately, someone was manipulating things around, so that four people could control one. Someone set up a bracket in front and under the command of the person in front, he kept adjusting the position of the bracket. One person in the back row quickly pulled a winch.

The winch was placed on a car, and the distance was too far, so I couldn't see clearly what it was for. However, the sound of wood friction continued, which made the hearts of the Yuan army guarding the city sink down little by little.

Another person was standing next to him, holding a bundle of spears in his hand.

This time, it was not just a lift, but a total of thirty units were operating at the same time. After some operation, with the order of a general wearing soft armor in the front row, the soldiers holding spears quickly placed the spears side by side in grooves.

"put!"

As the front row commanded the order flags swayed down, thirty monster crossbows were activated at the same time. Even though they were two hundred steps away, the tremors of the bowstrings that sounded at the same time were still clearly heard.

At this time, Yuan Shao realized that the spears were giant arrows, giant arrows more than ten feet long!

With a buzzing sound, nearly two hundred giant arrows rose into the air, and with the sound of whistling that made the air chaotic, it had already reached the top of the city.
Chapter completed!
