There are gentlemen in the Three Kingdoms

This time, it was Cao Jun's horn that rang out.

The pottery merchant was on the top of the city, looking at the city not far away, the elite soldiers and generals of the two sides were fighting, the battle was very fierce, and there were ups and downs in his heart.

At this moment, Cao Jun's rear formation sounded horns in the distance, which immediately attracted the potter's attention.

He narrowed his eyes, pondered for a while, and said, "It seems that Cao Cao also has a backhand."

Lu Su stood behind the potter, and said: "Cao Cao is also a strong man in the world, and his behavior is absolutely extraordinary. It seems that he must have arranged other soldiers to be around Qufu. When the battle is stalemate, he will come to us. Unleash a thunderous blow for full success."

The potter nodded and thought about it: "Among the four gates at present, the west gate is the weakest. Although I specially arranged for Tao Ji to guard there, I'm afraid there will still be accidents, so please take it for me. "

"The prime minister has an order, Su Ding will do his best!"

After Lu Su finished speaking, he hurriedly went down the tower.

Sure enough, in the woods outside the west city, a Cao Jun who was waiting for the battle appeared. After receiving Cao Cao's military order, he immediately killed the general and went straight to the west gate of the city.

Liu Xun used to be Yuan Shu's general in the past, he was not good at fighting to the death, but he was the best at using strange things.

Most of his soldiers hiding in the forest had fire starters on them.

Dozens of rockets pierced the sky and shot at the city gate to the west of Qufu. With a bang, a fire was set off at the city gate, while Cao Jun, who had prepared fire igniters and hay, rode on At this moment, it seemed that he ran to the bottom of the city and threw those fire objects towards the city gate.

And Liu Xun's strange moves kept going. After setting the fire, he immediately ordered the soldiers to push a simple cart to attack the city gate.

"boom"

"boom"

The sound of rushing cars hitting the city gate was deafening.

Tao Ji looked at the situation below from the top of the city, and said loudly: "Smash their ram!"

He knew that the city gate would become vulnerable if it was attacked by fire, and now it was attacked by a car, even if the car was very simple, it must be broken.

On the top of the city, many elite soldiers from Danyang threw stones at the chariots. Although their chariots were forced back temporarily, anyone with a discerning eye knew that the gates of the west city might not last long.

Lu Su hadn't arrived at the west gate yet, but he had already heard the report from his scouts.

Hearing the situation of Ximen, Lu Su pondered for a while, and then immediately said: "Report to General Tao Ji quickly, let him abandon the outer city, and use the urn city of Xicheng to block Liu Xun's attack."

Chapter 825

Lu Su shouted loudly: "Let them in, use the urn city to fight against the enemy!"

As a result, the Jinling army gave up the outer defense and let Liu Xun's soldiers attack the gate of the west city vigorously.

After a while, the ground below the west city seemed to tremble suddenly, and many soldiers almost felt like they were about to fall to the ground.

Immediately afterwards, a voice like a mountain roar and a tsunami came: "The city is broken! The city is broken!"

And Cao Jun had rushed into the city frantically, and the outer city of the West Gate City of Qufu City was finally knocked open.

"Kill!" Cao Jun rushed into the Urn City braving the fire he had just set in front of the city gate.

"If you come here, you will die!" Lu Su said coldly.

Countless Cao Jun took the opportunity to rush into the Wengcheng.

"Shoot the arrows, let the arrows go! Shoot them to death!" the Jinling army shouted.

"Hold it! Hold it! Take down the gates of the inner city, and they will be finished!"

The storm of ice-cold devices shuttled back and forth in the Urn City controlled by people, frantically harvesting people's lives.But at this time, no one cares about it.

For the two parties, since the Urn City has been broken, there is no room for turning this war around.

Either life or death.

But compared to Liu Xun and the others, Lu Su took far higher risks than them.

Because his ambush on the inner city tower at the moment is not so much sufficient, and after the Jinling soldiers under his command have completely gained the upper hand at the top of the city, the inner gate may have been occupied by Liu Xu long ago. The soldiers and horses smashed 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 battle in the Wengcheng became more and more intense, a loud bang was suddenly heard, and the gate of the inner city was also knocked open by Cao Bing.

"The city is broken!"

Cao Jun's soldiers rushed into the city like crazy.

Faintly, I could still hear Liu Xun's laughter: "It's a mere urn, what can I do! There is no city that Liu wants to break, and there is no city that cannot be broken!"

"The city gate has been lost! Qufu has been broken! The Tao thief is quickly killed!"

Cao Jun's soldiers were shouting, their voices beating in the air like ignited kerosene, burning people's hearts hotly.

Lu Su was not in a hurry, he just quietly looked at the crazy Cao Jun soldiers in the urn city, and suddenly said: "Order Zhang Xiu and Zhang Xun to seize the city gate and release the Qianjin gate!"

In the distance, the pottery merchant in charge of commanding the main battlefield seemed to have heard something was wrong at the west gate.

He sighed, and said helplessly, "Finally, are you going to release my Qianjin gate? Unfortunately, I originally hoped to use this thing to catch a big fish."

The design of the Qianjin gate had been studied in Jinling City several years ago, based on the potter's proposal.

However, there are many physical and mechanical principles in the design of the Qianjin gate, and the production cost is relatively high, requiring a large amount of iron tools. Even Jinling City, which has Jinling Iron Mine, dare not promote it on a large scale. Key cities are used for construction.

Qufu's inner and outer Qianjin gates are made of iron-covered solid wood, covered with iron nails for reinforcement. The gates are 6 meters wide, 6.5 meters high, and 9 centimeters thick. The mass is about 1000 kilograms. , the gate rises to the gate groove in the city platform above the gate opening; when the gate is closed, the gate falls smoothly from the gate groove, forming an "unbreakable" barrier.

As long as this thing is used properly once, it can trap Cao Jun who was caught off guard in the Wengcheng.

"Let go!" Lu Su shouted loudly.

The technical requirements for driving the jack gate are relatively complicated, which is why Jinling City has used the jack gate for practical use after years of research and adjustments.

The jack gate is controlled by the winch column, and each winch column is about 1 meter above the first floor, and there will be two jacks for the winch, which are the axes of the cross winch.

The top of the gate slot is located 2.8 meters south of the two winches, and the gate slot is 6.2 meters long.There is a piece of supporting stone between the two winches leading to the gate groove in the south, and there is also a pulley fixing groove at the front end of the supporting stone.

There are positioning plate fixing grooves and twisted rope sliding control structure fixing grooves on the supporting stone. This pair of grooves mainly controls the rope of the jack gate, which rises and falls from the gate groove to the pulley at the front end of the "supporting stone", and passes through the "supporting stone". Devices such as the "notch" of the positioning plate are connected to the winch column, and the winch is manually turned to exert force to lift the jack gate.

Contrary to what the potters originally imagined, the Qianjin gate was not dropped all at once.

Because although this kind of thing is heavy, it is most afraid of putting it on the wrong side. As long as it is slightly off, it will get stuck, unable to go up and down, and it will be very troublesome.

Therefore, in order to buy time, Lu Su asked Tao Ji to set up an array in the Wengcheng, and at the same time dispatched two generals who had been arranged in advance, Zhang Xiu and Zhang Xun, to defend on the gates of the outer city and the inner city, occupying a favorable position. , so that the jack gate can be lowered slowly.

At the gate of the inner city, Zhang Xiu personally led an army on foot, guarding the gate, stabbing it with long spears, desperately resisting it, and preventing the opponent from boasting one step further.
