The Sui army was able to siege the city through many battles and was very well-organized. The first thing was to use long-range weapons to suppress the opponent. Using heavy trenchers is a method. Building a trench mountain that exceeds the city wall and occupying a height is also a method. Compared with the two solutions, the use of heavy trench machines is convenient and fast, and it is not restricted by the site. It can be launched at the same time. Building a trench mountain is not only time-consuming and laborious, but also only a few trench machines can be placed on the top of the mountain, which has poor strike effect.

But building a earthen mountain has a huge advantage, that is, it can bring a heavy blow to the enemy's morale. Every day, looking up at the huge rocks flying from the top of the mountain, the huge pressure can destroy the enemy's fighting will.

Zhang Xuan once beat Meng Dangui to the point of being beaten in Donghai County and Dongping County. He knew Meng Dangui very well. After several months of comprehensive observation, he found that Meng Dangui's fierce and cruel side was as timid as a mouse. His psychological endurance was probably not as good as an ordinary soldier. So Zhang Xuan decided to work in both ways and use huge pressure to destroy Meng Dangui's resistance.

That night, a five hundred-step wooden wall stood along the north side of the moat. The wooden wall was two meters high and very wide. It was covered with a layer of soil, enough to withstand the attacks of bows and rockets on the top of the city. Just behind the wooden wall, 50,000 troops acted together, carrying trucks of soil with shoulders, transporting trucks and baskets of soil next to the wooden wall. The foundation of the dirt mountain was formed the next day.

The thief army on the city wall was afraid all night and they could not see the situation opposite. The long wooden walls covered the Sui army's actions. On the north side of the Sui army camp, a circle of torches around shone a large area of ​​open space as daytime. Hundreds of craftsmen were busy building heavy trench machines. All the heavy trench parts were transported by large ships, and they could be put into battle as long as they were simple assembled.

Zhang Xuan was inspecting the assembly of the catapult under the escort of dozens of personal soldiers, accompanied by a craftsman's manager next to him. "How many catapults are there in total?" Zhang Xuan asked.

"Report to your Highness, a total of fifty catapults were transported this time, and all of them can be installed tonight!"

Zhang Xuan nodded and then came to a trencher that had been installed. He looked up at the trencher that was almost as tall as the city wall, standing in front of him like a giant.

"How powerful is this trencher?" Zhang Xuan asked, patting the thick wood.

The manager walked up and smiled and said, "Shooting upward from the city can throw a huge rock weighing 100 kilograms away from two hundred and fifty steps. If installed on the city, the range can reach 350 steps, and with a winch to be used, it only takes fifty people to control it."

"Can a wooden wheel be installed below?" Zhang Xuan found that there was no wooden wheel beneath.

"If there is a wooden wheel, it will be installed immediately. You need to use a ox to pull it to the battlefield."

At this time, Zhang Xuan turned around to Luo Shixin who accompanied him to inspect: "Don't wait for the earth to be piled up, and fifty catapults will take action tomorrow."

"Abide by the orders!"

When it was just dawn, you could see the situation behind the wooden wall from the city wall. The foundation of a 100-acre earth mountain covering an area of ​​100 acres and reaching 100 meters high was tamped with huge bluestone around it, which shocked the defenders.

Not long after, Meng Dangui also rushed over when he heard the news. He was stunned by the scene in front of him. He saw countless Sui soldiers flowing through the flow and piled up a cart of mud onto the dirt mountain. He immediately understood the intention of the Sui army, and was suddenly panicked and confused, but he didn't know what to do. They were originally condescending, but now they have become condescending. How can this city be guarded?

"General, what should we do?" asked a deputy general next to him.

"There is no need to be afraid of this, the Sui army is just bluffing."

Meng Dangui turned around and said to all the soldiers: "Do you understand? Bluff."

As soon as he finished speaking, he heard a loud bang, and soldiers from the direction of Xicheng shouted, followed by a huge sound.

Meng Dangui was shocked and shouted: "What's going on?"

The generals looked at each other, and no one knew what happened? At this time, a soldier rushed over and shouted in fear: "General, the Sui army's catapult has launched an attack on the city!"

Meng Dangui's heart trembled. He walked quickly towards the west city without saying a word. He was extremely nervous. He followed a large group of generals, and his face was full of uneasiness.

When everyone was less than twenty steps away from the battlement wall of the west city, the soldiers in front suddenly shouted and all lying on the ground. A huge rock weighing more than 100 pounds hit the battlement. The gravel flew upwards, and the huge rock bounced upwards, and roared past Meng Dangui's head, and just hit the crowd of generals behind him. Only a scream was heard. Seven or eight generals were hit by the rolling rocks, and two generals were smashed into meat pie and fell into the city with the huge rocks. The other five generals were either dead or injured, and fell to the ground and groaned in pain.

Everyone's face was pale and they rolled and crawled under the city wall with Meng Dangui. After a while, they slowly raised their heads and looked down at the city from the battlement. They saw fifty or sixty heavy catapults lined up in a row more than two hundred steps away, just like fifty giant gods standing on the field, being controlled by Sui soldiers, shot with a long pole, and constantly smashing the huge rocks towards the city. All the soldiers were suppressed so that they could not raise their heads. Hundreds of soldiers had died tragically under the blow of the huge rocks.

Meng Dangui was frightened and trembled. He didn't want to come to defend Wuxi City at first, but was forced by his elder brother Meng Haigong. Faced with such a powerful Sui army, his confidence began to collapse little by little.

Fifty thousand troops accumulated day and night. In just five days, a mountain of earth as high as eight feet tall stood under Wuxi City, nearly three times higher than the city wall, which made the soldiers on the city frightened. But what really caused the Wuxi city defense to suffer a severe blow was the Sui army's fifty stone-cattering aircraft bombarded for five consecutive days. The west city wall was almost collapsed, and the city was no longer alone. Most of the Xicheng defenders had retreated to the city, and the morale of the bandits was extremely depressed.

At this time, two thousand Sui army crossbowmen on the Tushan began to shoot arrows to the north city. The dense rain of arrows suppressed the bandit soldiers on the top of the city. The defenders suffered heavy casualties and even their shields could not stop the sharp and heavy arrows shot from their heads. The soldiers rushed to the city one after another.

The conditions for attacking Wuxi County finally ripe. At noon, Zhang Xuan issued an order to attack Wuxi City. The routine of attacking Wuxi City was exactly the same as attacking Hefei City. More than a dozen thousand-stone warships sailed into the moat and moored in the north city and the west city walls respectively. Sui soldiers quickly built a floating bridge. 20,000 Sui soldiers rushed to the floating bridge and rushed to the top of the city with the help of a large ship. At this time, the Sui army's catapults and bows stopped attacking. There were no defenders on the top of the city in Xicheng and Beicheng. 20,000 Sui soldiers rushed to the top of the city without any obstacles and rushed into the city.

At this moment, the only southern city gate that could escape opened, and countless thieves rushed out of the city frantically, threw away their armor, and ran into the wilderness without any chance. But they didn't know that just one mile away, ten thousand cavalry and twenty thousand infantry had already set up a net of heaven and earth in the wilderness.

At this time, the master general Zhang Xuan issued a killing order, "No mercy to kill!"

Zhang Xuan wanted to use the heads of Meng Haigong's soldiers to completely buy the hearts of the people in Jiangnan. The horses galloped and the swords flashed. Ten thousand cavalry came like a tide, killing every bandit soldier ruthlessly. No matter how they knelt down and begged for mercy, they still could not escape death. The wilderness was full of corpses, and the blood stained the land red. Just as soldiers escaped the pursuit of cavalry, they could not escape the killing of the peripheral infantry. This was a massacre without any suspense. Almost all the nearly 50,000 Meng Haigong's soldiers were massacred.

At this time, a group of soldiers took a man in women's clothing to Zhang Xuan, "Master, this person is Meng Dangui. He was wearing women's clothing and wanted to get into the city, but was reported by them!"

Meng Dangui knelt down on the ground, kowtowed desperately and begged for mercy. Zhang Xuan looked at him coldly, "I think it's dirty to kill you, I strip him naked and leave it to the people in the city to deal with!"

Meng Dangui was so scared that he was incontinent and fainted. An hour later, Meng Dangui was bitten by tens of thousands of extremely angry people, and even his bones were trampled into pieces by the angry crowd.
