To the north of Guandu, more than a dozen huge counterweight trebuchets, a fusion of Mongolian siege equipment from the Western Regions and siege monsters with Fang Guang's martial arts skills, stood in front of the two armies' formations and behind the complex tunnels.
Among the trebuchets, there is a short man with a huge head, wearing a red robe and a high crown, which is quite eye-catching.
Liu Ye, the young minister of the Han Dynasty, also wore the same clothes when he was in Yangzhou on the night when he killed the evil servant of the family on his mother's orders.
In front of the two armies, Liu Ye's body was trembling slightly. From beginning to end, Liu Ziyang, who followed Fang Guang's orders and built the equipment in front of him, was also the person in the world, other than Fang Guang, who knew the sharpest person in front of him the most.
On one side of the thick trebuchet lever, a counterweighted stone lock made by a stonemason stood high in the air, glowing dimly under the winter sunshine in Xuchang.
There are more than a dozen thunderbolt chariots, and each one is equipped with more than a dozen strong soldiers, as well as several piles of round stone bullets stacked together.
In order to grind out the ammunition used in these thunderbolt vehicles, Liu Ye mobilized thousands of people and worked day and night, collecting almost all the suitable stones near the small town of Guandu, and even split and disintegrated the stone lions in front of the government office.
Only then did I get these marbles.
Liu Ye swallowed hard when he thought of the power of the marbles that were like meteors, streaking across the sky of Guandu and hitting the walls of the hills during the first test firing.
It's a pity that this thing disintegrated and was too cumbersome to transport, and the stone marbles were not easy to polish. But Liu Ye thought, what kind of infantry and cavalry does the big man need?
As long as thousands of Thunderbolt Chariots line up in a row and can hit all the way from Guandu to Yanjin, then to Yecheng and Yijing, no one will be able to stop them.
About a hundred steps behind Liu Ye, Cao Cao, together with Cao Ying's civil and military forces, looked at the thunderbolt chariot, which was much taller than the ordinary trebuchet, and started talking one after another.
Cao Mengde even held Fang Guang's hand and kept asking about the details of the construction of this Thunderbolt car.
Hearing that if the strength is properly matched, this object can hit up to four hundred steps, and it is as heroic and majestic as Cao Cao, it can't help but take a breath.
Four hundred steps is equivalent to about 600 meters away. Ordinary people can't see clearly at such a distance, and the bow and arrow are far out of reach.
Although this thing is clumsy, if it is equipped in the army, it can be invincible whether it is a city siege or a field battle. It can also be fired from a distance to force the enemy to rush into the formation and destroy the vehicle. It is really a weapon that defies heaven.
Cao Cao looked up and down at the Pili Chariot, which looked like a hill with wooden wheels on its chassis, and swallowed lightly.
"Datong, can this thing really hit Yuan Jun's wooden building? Should we push it closer? I'm afraid it will be more lethal!"
"I think it's not difficult to break wood with rocks, but it's probably much more difficult to break through soil."
It was rare for Fang Guang to see the big boss's confused expression. The corners of his mouth turned up in a bright smile.
"Ming Gong, not to mention this rammed earth, even the stone city wall covered with glutinous rice juice cannot stop Zi Yang's thunderbolt chariot!"
"This thing has a lever and uses the potential energy of gravity to shoot it out. My lord, look at the stone bullets. Are they bigger than the stone bullets fired by ordinary siege equipment?"
"The weight of an object's potential energy is crucial. The heavier the weight, the faster the speed. The increased killing power can be calculated in multiples. A rammed earth wall? Even the city wall of Yecheng, if my thunderbolt car leans against it, it will be destroyed in an instant.
!”
"If you dare to rely on the strength of the city in front of Duke Ming, it will never happen again in the world!"
Fang Guang talked eloquently, which made Cao Cao very excited. Although the boss didn't understand what potential energy and gravity were, he just looked at Datong's tone and said that he was reliable.
Cao Cao was convinced by Fang Guang, but Xun Yu knew that science and engineering were his weaknesses and kept his clumsiness to himself. Yang Xiu was frivolous and dissatisfied, so he couldn't help but speak up and pour cold water on him.
"Lord, Datong, it's not that I don't believe in Datong. Let's ignore the thunderbolt chariot for the moment. The stone struck by this thing should not be more rugged and full of sharp corners, so the more lethal it is?"
"I read the book of Emperor Guangwu, the founding father of this dynasty. During the Battle of Kunyang, the warriors in Wang Mang's army were also equipped with this thing, specializing in finding strange rocks to attack the city!"
"The stone in Datong is round and smooth, even smoother than an egg. Isn't it a lot different?"
Yang Xiu, who had read the most miscellaneous books, spoke with solid evidence, which made Cao Ying Wenwu, who was originally convinced by Fang Guang, feel a trace of doubt in his heart.
Da Sinong turned around, glanced at Yang Xiu with a look that cared for the mentally retarded, and smiled disdainfully, not even bothering to explain. Yang Xiu suddenly heard Fang Guang's voice.
"The roundness of this stone is to increase the striking area and make it easier to control the flight trajectory. This is intentional!"
"There are several pages describing this matter in the Physics book of Cangting Academy, The Way of Strength. I have tried them one by one, and there is no mistake!"
Everyone looked at the sound and saw that Fang Guang was speaking with a calm expression and his long eyes under his thick eyebrows shone with the light of wisdom. Fang Guang was standing behind Sima Fang. It was Sima Bada, the smartest Sima Yi.
"So that's it. Since Datong uses the way of heaven and earth to turn into sharp weapons of attack, today will be the day when Hebei's soldiers and horses are defeated!"
"In a moment, Yuan Jun's wooden city will collapse and the stone walls will collapse. You should follow me to kill the enemy and destroy Yuan Shao today!"
"promise!"
"Just follow the Lord's orders!"
All the generals in Cao's camp drew their swords together and let out loud shouts. Fang Guang took a deep look at Sima Yi and narrowed his eyes.
Fang Guang personally came to the big drum a dozen steps in front of him, took the drumstick from the infantryman's hand, and struck the drum head hard.
Not far away, Liu Ye heard the sound of the attack and felt short of breath, almost bursting into tears.
With the word "Fa!" repeatedly, the strong soldier in the army suddenly pulled down the counterweight stone lock, and the low buzzing sound made Fang Guang's heart shrink.
The huge stone marbles flew towards the earthen wall of Yuan Jun's wooden city not far away with a high trajectory.
"Boom!"
The whole earth seemed to tremble. A dozen stone bullets were fired, one too close and two too far, hitting Yuan Jun's camp directly.
Most of the remaining projectiles hit the wooden city. How could a wooden building withstand such a strong force?
No matter where the stone projectiles hit, the wooden city would collapse as soon as it touched the slightest thing.
The stone marbles that smashed Mucheng continued to fall among Yuan Jun's soldiers, causing screams in an instant.
In Yuan Shao's camp, the leader of Hebei Province, who was still teasing and scornfully talking about Cao Jun's strange weapons, was alarmed by the loud noise, strode out of the tent, and looked towards the front village not far away.
The scene he saw at the first sight made Benchu, who had always been a man of aristocratic family and always be calm in everything, couldn't help but let out a soft cry, took a few steps back, and pressed his back against the wall.
A stone bullet hit the platform where the crossbowmen gathered in Mucheng. After breaking the beams of Mucheng, it passed through the screaming Yuan Jun crossbowmen.
Arms, thighs, and a few human heads flew into the air, and along with the scattered wood chips, they reflected in Yuan Benchu's eyes.
The falling projectile still had a fierce momentum and hit Yuan Shao just a few dozen steps in front of him. Hebei elites wearing heavy armor screamed again and either fell to death or covered their mutilated bodies in front of their lord.
