Lu Su shouted loudly: "Let them in and use the Wengcheng to fight the enemy!"
As a result, the Jinling Army gave up its peripheral defense and allowed Liu Xun's soldiers to attack the Xicheng gate vigorously.
Not long after, the ground below the West City seemed to shake suddenly, and many soldiers almost felt like they were about to fall to the ground.
Immediately afterwards, a sound like a roaring mountain and a tsunami was heard: "The city is broken! The city is broken!"
But Cao Jun had already rushed into the city crazily, and the outer city of Qufu City's west gate was finally knocked open.
"Kill!" Cao Jun braved the fire he had just set in front of the city gate and rushed into the urn city.
"No matter how many people come, they will die!" Lu Su said coldly.
Countless Cao troops took the opportunity to rush into the Wengcheng.
"Fire arrows, fire arrows! Shoot them to death!" The Jinling troops were all shouting.
"Hold on! Hold on! Capture the inner city gate and they will be finished!"
The ice storm was controlled by people and shuttled back and forth in Wengcheng, harvesting people's lives crazily. But at this time, no one paid attention to it.
For both parties, now that the barbican city has been destroyed, there is no room for change in the war.
Either life or death.
But compared to Liu Xun and others, Lu Su took far higher risks than them.
Because his ambush on the inner city tower at the moment is not that large and sufficient, and when the Jinling soldiers he can command will completely gain the advantage at the top of the city, the inner gate may have been occupied by Liu Xu.
The soldiers and horses crashed away.
Once the gate of the inner city is broken, there is no doubt that the potter's rear will fall into the deepest crisis.
As the fighting in Wengcheng became more and more intense, a loud bang was heard suddenly, and the gate of the inner city was opened by Cao soldiers.
"The city is broken!"
Cao Jun's soldiers rushed into the city like crazy.
Faintly, it seems that Liu Xun can still be heard laughing: "It's just an urn city, what can I do! There is no city that Liu wants to break that cannot be broken!"
"The city gate has been lost! Qufu has been destroyed! The Tao thief will die quickly!"
Cao Jun's soldiers were shouting, their voices beating in the air like ignited oil, burning people's hearts.
Lu Su was not in a hurry, he just looked quietly at the crazy Cao Jun soldiers in Wengcheng, and suddenly said: "Send orders to Zhang Xiu and Zhang Xun to seize the city gate and release the Thousand Jin Gate!"
In the distance, the potter responsible for commanding the main battlefield seemed to have heard something was wrong at the west city gate.
He sighed and said helplessly: "Finally, are you going to release my thousand catty gate? Unfortunately, I originally hoped to catch a big fish with this thing."
Jinling City began to study the design of Qianjin Gate a few years ago based on a proposal from a pottery merchant.
However, the design of the Thousand Jin Gate has many physical and mechanical principles, and the production cost is high, requiring a large amount of iron tools. Even Jinling City, which owns the Jinling Iron Mine, does not dare to promote it on a large scale.
Key cities are used for construction.
As for Qufu's inner and outer gates, the gates are made of iron-clad solid wood and are covered with iron nails for reinforcement. The gates are 6 meters wide, 6.5 meters high, and 9 centimeters thick. The mass is calculated to be more than 1,000 kilograms. When the gate is opened,
, the gate rises to the gate slot in the city platform above the door opening; when the gate is closed, the gate falls smoothly from the gate slot, forming an "unbreakable" barrier.
As long as this thing is used properly once, it can trap all the unprepared Cao soldiers in the Wengcheng.
"Let go!" Lu Su shouted loudly.
The technical requirements for driving a thousand-jin gate are relatively complex, which is why Jinling City put the thousand-jin gate into practical use after years of research and adjustment.
The jack brake is controlled by a winch column. Each winch column has two winch jacks about 1 meter upward from the first floor, which are the cross winch axes.
The top of the gate slot is located 2.8 meters due south of the two winches, and the gate slot is 6.2 meters long. There is a support stone directly south of the two winches leading to the gate slot, and there is a pulley fixing groove at the front end of the support stone.
There are positioning plate fixing grooves and rope sliding control structure fixing grooves on the supporting stone. This pair of grooves mainly controls the rope of the jack gate, which is lifted from the gate groove to the pulley at the front end of the "supporting stone", and then passes through the pulley on the "supporting stone".
The positioning plate "notch" and other devices are connected to the winch column, and the winch is manually rotated to generate force to raise and lower the jack gate.
Contrary to what the potter originally thought, the Qianjin gate did not fall down immediately.
Because although this kind of thing is heavy, it is most afraid of being misplaced. As long as it is slightly misplaced, it will get stuck and cannot go up or down, which is very troublesome.
Therefore, in order to buy time, Lu Su asked Tao Ji to set up a formation in Wengcheng, and at the same time sent two generals, Zhang Xiu and Zhang Xun, who had been arranged in advance, to defend at the gates of the outer city and the inner city to occupy a favorable position.
, so that the Qianjin Gate can slowly descend.
At the gate of the inner city, Zhang Xiu personally led an army on foot to guard the gate. He kept poking at the gate with his long spear and held on with all his strength to prevent the opponent from overstepping the mark.
The outer city is more troublesome, because there are no soldiers who can go down to fight on foot, so they can only defend themselves with arrows on the top of the city. Use bows and crossbows to shoot the soldiers outside the city to prevent them from entering the city in large numbers, while Cao's soldiers inside the city
He focused on the inner gate and paid little attention to the outer city gate. This, to a certain extent, relieved a certain amount of pressure.
Although the Thousand-jin Gate fell little by little, it was not too slow. After a while, two loud noises of "boom, boom, boom" were heard, and the Thousand-jin Gate finally slowly fell to the ground.
The soldiers of Cao Cao in Wengcheng went crazy.
"What is this?"
"Open it! Open the door!"
"No! It won't move at all, it's too heavy!"
"What the hell is this?"
At this moment, Liu Xun followed the soldiers and rushed into the city. He looked around and saw that both the front and rear doors were blocked, and he couldn't help but feel a chill in his heart.
"What's going on? Rewind, rewind!"
Just when Liu Xun was roaring loudly, a voice suddenly came from the tower behind: "Liu Xun, dog thief, I never thought you would be here today?"
Liu Xun hurriedly looked up and saw that the person speaking was Zhang Xun, the general of the Jinling Army and his former colleague.
"You, is it you?" Liu Xun's face turned pale instantly.
Zhang Xun sneered and said: "That's right, it's me. You didn't expect it, did you? Liu Xun, the dog thief, back then you betrayed the lord and colluded with Cao Cao's thief, causing the general and his son to die with hatred. However, you went to your old friends to seek wealth. Now you deserve
Follow the report!"
Liu Xun looked around at the city that was like an iron barrel, and fear suddenly arose in his heart.
"Zhang, Mr. Zhang! For the sake of our colleagues who have been together for many years, please let me live! I will repay this great kindness to you a hundred times or a thousand times in the future! When I surrendered to Cao Sikong, it was also
I have no choice but to do so!”
"We have no choice?" Zhang Xun sneered and said, "Even if what you say is true, I am not the only one here who wants your life! Can you persuade them all?"
