The sudden change began to be chaotic on the Yellow River, and more than 100 small boats fled to both sides of the Yellow River, but the Sui warships pursued mercilessly, and the arrows on the big ships were like rain, and the soldiers on the small boats could not resist, and they fell into the water with arrows, and the big boats immediately knocked over the small boats.

This was a massacre without suspense, 20 Sui warships rampage on the Yellow River, in just one hour, more than 100 boats crossing the river have been destroyed, more than 90% of the remaining dozen boats are desperately fleeing, not daring to stay on the Luxian River for a moment.

On the south bank of the Yellow River, Dou Jiande was stunned at everything that happened on the river, and his mind became blank, perhaps because of his long-term life in the north, Dou Jiande did not have any intuitive awareness of the warship.

Even if the ships on the Yongji Canal came and went, most of them were cargo ships, and there were no warships, let alone Wuya warships rampant on the Yangtze River.

But the situation in front of him made his heart seem to fall into a cold cave, Zhang Xuan didn't give him any chance at all, the so-called two days to consider, it only made him choose to return north, once he showed signs of going south, Zhang Xuan did not hesitate to send troops.

Dou Jiande finally deeply realized the strength of his opponent, and he also understood why Zhang Xuan was able to defeat Zhang Jin's 100,000 army with 6,000 troops.

He began to feel uneasy in his heart, he only had 25,000 troops now, could he defeat Zhang Xuan's 20,000 troops?

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

At this moment, a cavalry galloped 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 cavalry has just shot on the city wall, Zhang Xuan's letter to Dou Gong." ”

Dou Jiande hurriedly took the letter, only to see that the letter jacket read, 'Qinghe Tongshou and Hebei Envoy Zhang Xuan sent a letter to Dou Gong Jiande'.

He opened the letter and read it carefully, in which Zhang Xuan gave him an ultimatum, demanding that his army surrender within two days. All the troops can be sent north and let them return to their hometowns, otherwise 20,000 bandits will die on the south bank.

Dou Jiande was furious, tore the letter to shreds, pointed to the east and shouted: "Zhang Xuan'er, you deceive people too much!" ”

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

He led more than 1,000 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 stretched as far as the eye could see.

Zhang Xuan looked at the undulating wheat waves on both sides, and felt a kind of pressure on his shoulders, he must not let Dou Jiande ruin the summer harvest of Jibei County, and must wipe out the army on the south bank of Dou Jiande before the wheat is ripe.

Jae Hyun is still waiting for news from the scouts ahead. After a short time, several scout cavalry rushed back and reported to Zhang Xuanyu: "Commander Qiyu, the enemy army is defending the city, and there is no intention of going out of the city to greet him. ”

Zhang Xuan couldn't help sneering, and sure enough, he was expected by himself, Dou Jiande was strong on the outside and inside, and he didn't dare to really face the battle. Can you defend yourself by defending the city?

Jang Hyun turned around and ordered, "Keep going!" ”

The 20,000-strong army continued to march towards Lu County, and the city was getting closer and closer. The army finally stopped about a mile from the county seat, where there were no wheat fields, only a forest and some houses. The houses were razed to the ground, and tens of thousands of acres of wheat were all harvested, and there was not a single tree in the radius of several miles, and there was not a single tree in sight.

Not only outside the city, the walls are clear. The city gate was also replaced, and the old city gate was demolished and replaced with an iron-clad city gate, which was exceptionally strong.

The city is full of soldiers, stretching bows and arrows, waiting for the pillows, a big flag hunting and flying on the city tower, and a huge 'Dou' character is written on it.

At this time, Zhang Xuan ordered left and right: "Find County Lieutenant Liu!"

Liu Xin, the county lieutenant of Lu County, is a native of Lu County, and has been an official in Lu County, from a small official to a county lieutenant, and knows the situation of Lu County's city defense well.

Liu Xin, who was about forty years old and a very shrewd official, ran up to Shi Li and said, "See the big handsome!" ”

Zhang Xuan pointed at the city with a whip, "You said that this county has a great 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 it was about to collapse the year before last. ”

Zhang Xuan nodded, turned back to the herald behind him and said, "Prepare the trebuchet!" ”

The herald urged his horse to run behind, and heard him shout from afar: "Trebuchet ready!" ”

This time, Zhang Xuan brought three heavy trebuchets, the base and various huge parts were transported from Jishui in large ships, and more than a dozen craftsmen and hundreds of fortifications worked together, and in less than half an hour, three trebuchets like behemoth monsters stood on the field.

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

In the middle is the Phnom Penh Green Dragon Banner, which is the battle flag of the Blue Dragon Army.

In front of the military array, the trebuchet is as high as three zhang, and the long catapult is as long as five zhang, and it can be projected with an iron chain winch, which can throw a hundred-pound boulder to a distance of 300 steps, and it takes 50 people to pull it.

Zhang Xuan coldly ordered: "Enter the projection position!" ”

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

At this time, there was a commotion at the head of the city, the soldiers at the head of the city shouted in panic, and Dou Jiande, who was wearing armor, also ran to the side of the city wall, holding the battlements to check forward, and he couldn't help but gasp.

The city wall of Luxian County is two feet and five feet high, but the three towers on the opposite side are taller than the city wall, standing majestically in the distance three hundred steps away.

"Dou Gong, what should I do?" The soldiers asked worriedly.

Archery is impossible, the bed crossbow is still on the other side of the Yellow River, Dou Jiande has nothing to do, so he has to grit his teeth and say: "Try to dodge and see how arrogant it can be?" ”

On the field, a lieutenant reported to Zhang Xuan: "Boss Qiyu, the trebuchet is in place and can attack at any time!" ”

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

'Boom! Boom! Boom! The drums of the attack rang out.

The long throwing rod creaked and was pulled back, the winch was tightened, three thick ropes fixed the throwing rod on the falling iron post, and an eighty-pound boulder was placed in the iron pocket, and the soldiers quickly dodged to both sides.

At this time, the lieutenant shouted, "Launch!" ”

The knife cut the rope, 'Bang! With a loud bang, three boulders rose into the air and smashed towards the city wall in a zigzag shape in the air, and more than 100 soldiers at the head of the city in the southeast corner made a sound and fell behind the city wall.

The first two pieces hit the battlements respectively, 'Boom! With a loud bang, the battlements were smashed to pieces, and the two soldiers hiding behind the battlements were smashed into a blur of flesh and blood, and let out a scream, and the two boulders tumbled into the city.

But the third boulder hit the city wall, and with a loud bang, the city wall was smashed open with a large hole three feet wide, and the boulder fell into the wall, and it made a low muffled sound.

The defenders of the city looked at each other, and the inside of the wall was empty, and there was no earth or sand filled in, and everyone was afraid that if this continued, the wall would collapse.

At this time, the second round of three boulders rose into the air again, whistling towards the city wall, this time the trebuchet adjusted the angle, and the three boulders were accurately smashed on the city wall, and three large holes immediately appeared in the city wall, connected into one piece.

The head of the city began to shake, and the soldiers saw that the situation was not good, so they got up and fled, but some soldiers were still a step too late, only to hear a loud bang, and the head of the city, about a foot long, collapsed, and more than 20 soldiers screamed and fell into the black wall with the brick wall.

The dust cleared, and the city wall was torn apart and a big hole was opened, like a big mouth of a black hole, grinning towards the sky.

On the city wall, Dou Jiande took it to the ground and looked at the collapsed city wall, and he sighed in his heart, this city could not be defended at all.

Three boulders roared and smashed again, this time the problem was more serious, the boulders smashed more than a dozen pieces of wood on top of the city wall, the city wall was crumbling, boom, a section of more than 20 zhang long city wall collapsed, and the rotten dust filled the sky over the east city.

Dou Jiande couldn't calm down anymore, he shouted urgently: "Abandon the city, the whole army retreats west!" (To be continued.) )
