To the north of Guandu, more than a dozen huge counterweight trebuchets, fused with the siege equipment of the Western Regions of Mongolia and the siege monsters of Fang Guang's mechanical attainments, stood in front of the two armies, behind the complex tunnels.

Among the trebuchets, a man of short stature and a huge head, dressed in a red robe and wearing a high crown, was quite eye-catching.

Liu Ye, the young man of the Han Dynasty, was also dressed when he was in Yangzhou on the night when he was ordered by his mother to kill the evil servants in the family.

In front of the two armies, Liu Ye's body trembled slightly, from beginning to end, Liu Ziyang, who followed Fang Guang's order and created the equipment in front of him, is also the person in the world, except for that Fang Guang, who knows the thunderbolt in front of him best.

On the side of the thick rubble lever, the counterweight stone lock made by the stonemason is high in the air, emitting a dull luster under the winter sun of Xuchang.

There were more than a dozen thunderbolts, each with more than a dozen sturdy soldiers, and several piles of round stone bullets stacked together.

In order to polish the ammunition used in these thunderbolts, Liu Ye mobilized thousands of people, worked day and night, and almost collected all the stones near the small city of Guandu, and even split and decomposed the stone lions in front of the government to make up these stone bullets.

Thinking of the power of the bullet that swept through the sky of Guandu and smashed on the wall of the small hill like a meteor like a meteor, Liu Ye swallowed heavily.

Unfortunately, this material is decomposed, it is too cumbersome to transport, and the stone marble is not easy to polish. Does Liu Ye think that the Han still needs any foot soldiers, cavalry?

As long as thousands of thunderbolt cars are lined up, they can be smashed from Guandu, all the way to Yanjin, and then to Yecheng and Yijing, and no one will be able to stop them.

About a hundred paces behind Liu Ye, Cao Cao, together with Cao Ying's civil and military forces, looked at the thunderbolt cart that was far taller than the ordinary stone thrower, and began to discuss.

Cao Mengde even took Fang Guang's hand and couldn't help but ask about the details of the construction of this thunderbolt.

Knowing that if the strength is suitable, this thing can strike up to 400 steps, and the heroic atmosphere is like Cao Cao, and he can't help but gasp.

Four hundred steps, which is equivalent to about six hundred meters away, is such a distance that ordinary people can't see clearly, and the bow and arrow are far beyond reach.

Although this thing is clumsy, if it is equipped in the army, whether it is invincible in siege, it is a field battle, and it can also be fired remotely, forcing the enemy to rush into battle and break the car, which is really a weapon against the sky.

Cao Cao looked up and down like a hill, and the thunderbolt with wooden wheels on the chassis swallowed lightly.

"Datong, can this thing really hit Yuan Jun's wooden building? Is it to push it closer, but I'm afraid that the killing power will be greater! ”

"I think, it's not difficult to break wood with stones, but I'm afraid it's much more difficult to break the ground."

Fang Guang rarely saw the big boss's shocked expression, the corners of his mouth curled up, revealing a bright smile.

"Ming Gong, don't talk about this rammed earth, even the stone city wall with glutinous rice juice can't stop Ziyang's thunderbolt!"

"This thing has a lever, using gravitational potential energy to hit, the lord looks at the stone bullet, is it a few points larger than the ordinary siege equipment?"

"The potential energy of the object, the weight is the most important point, the weight is large, the speed is faster, the increased killing power can be calculated in multiples, rammed earth wall? It is the city wall of Yecheng, which was stopped by my thunderbolt car, but I am afraid that it will be wiped out in an instant! ”

"Dare to rely on the city in front of Ming Gong to defend it strongly, there is no such thing in the world!"

Fang Guang talked eloquently, and Cao Cao's heart was full of joy, although the boss didn't understand what potential energy and gravity was, just looking at Datong's tone, it was reliable.

Cao Cao was convinced of Fang Guang, Xun Yu knew that science and technology was his weakness, and he was clumsy, Yang Xiu was frivolous and unconvinced, so he couldn't help but open his mouth and poured cold water.

"Lord, Datong, it's not that I don't believe in Datong, this thunderbolt car is left aside for the time being, it's just the stone hit by this thing, shouldn't it be more rugged, the more sharp and it is, the greater the killing power?"

"I read the book of Emperor Guangwu, the founder of this dynasty, in the battle of Kunyang, Wang Mang's army, the wrestlers were also equipped with this thing, specifically looking for strange stones to attack the city!"

"Datong's stone is round and smooth, smoother than an egg, isn't it much worse?"

Yang Xiu, who had read the most miscellaneous books, spoke with evidence, which made Cao Ying, who was originally convinced of Fang Guang, feel a trace of suspicion in his heart.

Da Si Nong turned around, glanced at Yang Xiu with caring and handicapped eyes, smiled disdainfully, and didn't even bother to explain, Yang Xiu's ears suddenly heard a Fang Guang's voice.

"This stone is rounded, but it is to increase the impact area, and it is easier to control the trajectory of the flight, deliberately!"

"Cangting School, a book of physics, in the way of force, there are several pages of information about this matter, I try it one by one, there is no fallacy!"

Everyone followed the sound and looked, Fang Guang who spoke, his expression was calm, his long eyes under the thick eyebrows flashed with wisdom, Fang Guang stood behind Sima Fang, it was Sima Bada, the most intelligent Sima Yi.

"I see, since Datong uses the way of heaven and earth to attack and destroy sharp weapons, today is the time when Hebei's soldiers and horses are defeated!"

"After a while, Yuan Jun's wooden city, the stone wall will collapse, you should follow me to kill the enemy and destroy Yuan Shao, just today!"

"No!"

"By the Lord's command!"

The generals of Cao Ying drew their swords together and let out an earth-shattering shout, Fang Guang glanced at Sima Yi deeply, and his eyes narrowed.

Fang Guang personally came to the big drum more than a dozen steps in front of him, took the drumstick in the hand of the foot soldier, and struck the drum surface heavily.

Not far away, Liu Ye heard the sound of attack, only to feel shortness of breath, and tears were almost bursting out.

With a heavy "Fat! The word, a soldier in the army, violently pulled down the counterweight stone lock, and the buzzing low voice made Fang Guang's heart shrink.

The huge stone projectile, with a high throwing trajectory, flew towards the Yuan Junmu City and the earthen wall not far away.

"Boom!"

The whole earth seemed to tremble, and more than a dozen stone bullets, one of which was too close, and two were too far, smashed directly into the Yuan army camp.

The rest of the projectiles, most of which hit the wooden city, wooden buildings, where can they resist such a force?

No matter where the stone projectile hits, as long as the wooden city touches the slightest thing, it will collapse with an uproar.

The stone bullets that smashed the wooden city continued to fall among the Yuan army armorers, and there was a scream in an instant.

In Yuan Shao's camp, the Hebei lord who was still jokingly and contemptuously talking about Cao Jun's strange weapons was alarmed by a loud sound, strode out of the tent, and looked towards the front village not far away.

The scene I saw at first glance made the original, who had always paid attention to the style of the family and everything calm, couldn't help but snort softly, took a few steps back, and put his back on the wall.

A stone projectile that smashed on the platform where the crossbowmen of the wooden city gathered, after breaking the beams and pillars of the wooden city, grazed the exclamation of the Yuan Jun's crossbowmen.

Arms, thighs, and a few human heads flew into the air, and with the scattered sawdust, they were reflected in Yuan Benchu's eyes.

The falling projectile, the momentum was still fierce, and it smashed into a place only a few dozen steps in front of Yuan Shao, and the Hebei elite wearing heavy armor screamed miserably, or fell to death, or in front of the lord, covering the mutilated body, rolling on the ground and howling.
