The sudden change began to chaotic on the Yellow River. More than a hundred small boats fled to both sides of the Yellow River. However, the Sui army warships chased after them without mercy. The arrows on the large boat were like rain. The soldiers on the small boat could not resist them. They were all caught in the water. The big boat then knocked over the small boat.

This was a massacre without any suspense. Twenty Sui army warships rushed around the Yellow River. In just one hour, more than 90% of the river-crossing boats had been destroyed, and more than a dozen small boats were left fled desperately, and they did not dare to stay on the Luxian River for a moment.

On the south bank of the Yellow River, Dou Jiande stared at everything that happened on the river surface in a daze, and his mind became blank. Perhaps because of his long-term living in the north, Dou Jiande had no intuitive consciousness about warships.

Even when the Yongji Canal comes and goes, most of them are freight ships, and there are no warships, nor are there five-tooth warships rampant on the Yangtze River.

But the situation in front of him made his heart feel like he fell into a cold cave. Zhang Xuan did not give him any chance at all. The so-called two days of consideration were just to let him choose to return north. Once he showed signs of going south, Zhang Xuan would send troops without hesitation.

Dou Jiande finally deeply understood the power of his opponent, and he also understood why Zhang Xuan could defeat Zhang Jin with an army of 6,000 and call him a 100,000 army.

He began to feel uneasy. He only has 25,000 troops now. Can he defeat Zhang Xuan's 20,000 troops?

He began to realize that he had made a strategic mistake.

At this moment, a cavalry rushed over and stopped in front of Dou Jiande. The cavalry turned over and dismounted, knelt down on one knee and presented a letter: "This is the letter that the Sui army cavalry had just shot up the city wall, and Zhang Xuan's letter to Dou Gong."

Dou Jiande hurriedly took the letter, but the letter said, "The Qinghe Pass and Hebei recruitment envoy Zhang Xuan led Dou Gong Jiande."

He opened the letter and read it carefully. In the letter, Zhang Xuan gave him an ultimatum, asking his army to surrender within two days. All surrendered soldiers could be sent north and returned home, otherwise 20,000 riot bandits would die on the south bank.

Dou Jiande was furious and tore the letter to pieces, pointing at Dongfang and shouting: "Chun Xuan, you are too bullying!"

Dou Jiande immediately shouted: "Go back to the city!"

He led more than a thousand soldiers to Lu County.

………

Two days later, Zhang Xuan led an army of 20,000 to the wilderness about ten miles east of Lu County. At this time, the wheat began to turn yellow and the sea of ​​wheat was endless. Although a locust plague broke out in Jibei County last autumn, the summer grain harvest this year was good.

Zhang Xuan looked at the undulating wheat waves on both sides and felt a pressure on his shoulders. He must not let Dou Jiande destroy the summer harvest in Jibei County. He must wipe out Dou Jiande's army on the south bank before the wheat matures.

Zhang Xuan was still waiting for news about the scouts ahead. Soon, several scout cavalry rushed back and reported to Zhang Xuan: "You reported to the commander, the enemy was defending the city, and there was no intention of going out to greet him."

Zhang Xuan couldn't help but sneer, and he was indeed caught by himself. Dou Jiande was so mean on the outside and dared not really fight. Can he defend himself by defending the city?

Zhang Xuan turned around and ordered: "Continue to move forward!"

The 20,000 troops continued to march towards Lu County, and the city was getting closer and closer. The army finally stopped about one mile from the county town. There were no wheat fields in this area, only a forest, and some private houses. Dou Jiande implemented the strategy of strengthening the walls and clearing the fields, cutting down all the forests. The private houses were razed to the ground, and tens of thousands of acres of wheat were all harvested. It was bare within a few miles, without a tree, and no wheat waves could be seen.

Not only were the walls and clear fields outside the city, but the city gates were also replaced, but the old city gates were demolished and replaced with iron-clad city gates, which were particularly strong.

The city was full of soldiers, with bows and arrows, waiting for a pillow, a big flag was flying on the city tower, with a huge word "Dou".

At this time, Zhang Xuan ordered his left and right and said, "Come Liu County Magistrate!

Liu Xin, a county magistrate of Lu County, is a local from Lu County. He has always been an official in Lu County. He has been a junior official to a county magistrate. He knows the city defense of Lu County well. This time, Zhang Xuan attacked Lu County and specially brought him by his side.

Liu Xin was about forty years old and was a very smart official. He ran forward and bowed: "Meet the general!"

Zhang Xuan pointed to the city with a horse whip, "You said that this county town has a huge weakness, where is it?"

Liu Xin pointed to the southeast corner of the city wall and said to Zhang Xuan: "It's in the southeast corner, where the city wall has decayed and was about to collapse the year before yesterday. At that time, the county had no money to repair it, so I had to find some wood to support it in the city wall. The bricks were actually vulnerable."

Zhang Xuan nodded and turned to the messenger behind and said, "Prepare for the trencher!"

The messenger urged the horse to run back and heard him shouting from afar: "Prepare for the catapult!"

This time, Zhang Xuan brought three heavy trenchers, with the base and various huge parts transported from the Ji River by large ships. More than a dozen craftsmen and hundreds of fortification soldiers started together. In less than half an hour, three trenchers, like giant monsters, stood on the field.

On both sides of these three behemoths, 20,000 Sui troops were neatly arranged in formation, with their battle helmets reflecting the sun, their spears are like forests, their swords are shining, and thousands of battle flags are flying in the wind.

There is a golden-edged blue dragon flag in the middle, which is the battle flag of the Qinglong Army.

In front of the military formation, the catapult was as high as three meters high and the long catapult bar was as long as five meters long. It was cast with a chain winch type, and could throw a huge stone weighing 100 kilograms to three hundred steps, requiring fifty people to pull it.

Zhang Xuan said coldly: "Enter the projection position!"

The one-man-high wooden wheel was pushed by the soldiers, and the huge throwing stone began to move forward slowly.

At this time, the city was in agitation, and the soldiers on the city were yelling in panic. Dou Jiande, wearing armor, also rushed to the city wall and supported the battlements to check forward. He couldn't help but take a breath of air conditioning.

The walls of Lu County are two feet high, but the three towers opposite are taller than the city wall, standing majestic in the distance three hundred steps away. Even though Dou Jiande had experienced countless battles, he was still shocked by these three huge catapults.

"Mr. Dou, what should I do?" the soldiers asked worriedly.

It is impossible to shoot an arrow, and the crossbow is still on the other side of the Yellow River. Dou Jiande had no choice but to grit his teeth and said, "Try to avoid it and see how arrogant it can be?"

On the field, a lieutenant reported to Zhang Xuan: "Report to the commander, the catapult is in place and can attack at any time!"

Zhang Xuan looked at the city wall in the southeast and said coldly: "Attack!"

‘Dong!Dong!Dong!’ The sound of the attacking war drum suddenly rang.

The long throwing rod was pulled back creaked, the winch turned tightly, and three thick ropes fixed the throwing rod to the iron pile of the sinker. A large stone weighing 80 kilograms was placed in the iron pocket, and the soldiers quickly dodged to both sides.

At this time, the captain shouted, "Start!"

The sword cut off the rope, and with a loud "bang!", three huge rocks rose into the air and smashed towards the city wall in a font shape in the air. More than a hundred soldiers on the city head at the southeast corner made a sound and fell behind the city wall.

The first two pieces hit the battlements respectively. With a loud bang, the battlements were smashed to pieces and rocks flew. Two soldiers hiding behind the battlements were hit and bloody and screamed. The two huge rocks immediately rolled into the city.

But the third huge rock hit the city wall, with a loud bang, and a big three-foot-wide hole was smashed into the wall. The huge rock fell into the wall and made a low and dull sound.

The defenders on the city looked at each other, and the wall was empty and there was no soil or sand. Everyone felt scared. If this continued, the wall would collapse.

At this time, the second round of three huge rocks rose into the air again and roared towards the city wall. This time the catapult adjusted the angle, and all the three huge rocks hit the city wall accurately. Three large holes immediately appeared on the city wall, forming a whole.

The city wall began to shake. When the soldiers saw that the situation was not good, they stood up and fled. However, some soldiers were still one step late. There was a loud bang, and the city wall, about ten feet long, collapsed. More than 20 soldiers screamed and fell into the dark wall with the brick wall.

The dust dissipated, and a large hole was torn apart between the walls, like a big black mouth, opening into the sky.

Dou Jiande brought it to the ground and looked at the collapsed city wall. He sighed in his heart, and the city could not be defended at all.

Three huge rocks roared and smashed again, and this time the problem became even more serious. The huge rocks broke more than a dozen woods on the city wall in a row. The city wall was shaking. With a bang, a piece of wall more than twenty feet long collapsed, and rotten dust filled the sky above the East City.
