To build this ice and snow wall, the Qi army also spent a lot of effort. Long before the Qi army entered the customs, Li Yuandan was ready to cut down most of the trees near Chang'an City, in order to prevent the Qi army from building siege equipment for the latest chapter.

The ice and snow wall is sloping on both sides, making it look like a causeway. The side of the ice embankment facing the direction of Chang'an City is relatively rough, while the other side is very elegant, with slides and steps. Although these steps are also made of ice, there are many straws left on the ice surface, and they are not slippery to step on and are easy to climb.

Only by building this ice and snow embankment, the Qi army collected all the snow and vegetation within a radius of five miles. Tens of thousands of troops worked again and again, and it took a lot of manpower to build this embankment. This embankment is more than 60 steps away from the city wall, and is within the range of the arrows of the Western Xia army.

In fact, during the construction process, Li Yuandan felt that something was wrong, not only did he shoot arrows, but he also used the huge trebuchet in the city to try to destroy the ice embankment. However, these stones became the materials for the construction of the snow embankment, and as for the arrows, the soldiers of the Great Qi Army dodged behind the ice embankment, and no matter how powerful their bows and arrows were, they could not shoot them. As a result, this embankment had another role, and the Qi army could easily gather behind the snow embankment, and the Xia army had no idea what the Qi army was doing.

The Western Xia army made a fuss, but sent a lot of arrows to the Qi army. This time, Li Yuandan died down, and he asked people to closely monitor to see what the Qi army wanted to do.

There you have the answer. Early in the morning of November 20, just after the dawn, the Xixia army on the gate of Chang'an suddenly found that there were suddenly rows of huge wooden frames on the ice embankment, and these wooden frames were secretly transported up by the slide behind the ice embankment last night. These days, every night, the Qi army beats gongs and drums on the ice embankment, and the noise is very happy. The Western Xia army was nervous for a while at first, but then it became numb, and let the Qi army toss, as long as the Qi army did not attack the city, it was easy to say anything.

The wooden frame on the ice bank consists of two kinds of instruments, one a trebuchet and the other an arrow stack, which stand next to each other. The Western Xia army had just given a warning, only to see a sharp arrow fly out from the arrow stack and go straight into the back of the Xia army's neck. Xin Yu, who had recovered, stood on the tall arrow stack, his face full of solemnity, letting the north wind blow his battle robe and rattle.

This arrow was like a military order, and in an instant, the archers on the various arrow stacks fired their bows at the opposite wall. The arrows shot out like flying locusts, so that the Western Xia army on the city wall couldn't raise their heads for a while.

At that moment, one after another trebuchets started to move, and instead of stones, they threw ice cubes the size of millstones. In this weather, it is too troublesome to dig the stones, and it is not convenient to transport. Xiao Dingguo asked people to chisel open the water and water, get out the big ice that was frozen two feet thick, and pull it to the snow embankment in one go.

This time, the two rivers in Baqiao Town, Bashui and Water, were used to the extreme. Large blocks of ice were used as ammunition for trebuchets, and small blocks of ice and river water were used to build snow banks.

Ice is much lighter than stone, and it can be thrown far, and the trebuchet is mounted on a solid snow bank that is almost as high as the city wall, and the range is increased by one point. Another key point is that these ice cubes are almost inexhaustible.

Where is this trebuchet, but a one-of-a-kind ice thrower.

World-large ice cubes and ice hockey balls flew into the city with a sharp cracking sound, destroying any standing buildings on the ground. Directly within a mile of the city wall, it became an unmanned belt. You must know that the Western Xia army is concentrated not far from the inner side of the city wall, and even if Daqi uses trebuchets, it can't reach them. Who knew that Daqi built such an ice embankment, and it was still ice cubes. This time, the Western Xia army suffered and was hit by the ice that fell from the sky, and it was still a mess.

Of course, if the ice falls from such a high place, it will break into many pieces when it hits the ground, unlike stones, which even if they crack, they will only break into three or five pieces. It is also because the ice is not as strong as the stone, so the broken Xiaoice pieces are splashed one by one, touching people's noses and swollen faces.

For a while, the screams in Chang'an City were endless. The ground in the entire range was covered with layers of ice, large or small. The Western Xia sergeants, who were hiding everywhere, were smashed to pieces. Although not many people died, the deterrent effect was enormous.

It was not only the city that was unlucky, but even the city walls were covered with ice, coupled with the suppression of the archers, the Western Xia army shrank behind the battlements on the city walls, and did not dare to show their heads in the latest chapter of the troubled times. As for the tall towers on the city walls, several large blocks of ice smashed into them, and they were still in ruins.

People rest, machines don't stop. On all sides of Chang'an City, the Baizuo Ice Thrower worked for a whole day, sending countless ice cubes to the city of Chang'an. In the inner city, near the four city gates, icebergs have been piled up.

The Western Xia army suffered heavy losses, and the Great Qi army was not easy. Although there are many ice blocks, it is not easy to dig and transport. All the Great Qi troops moved, and all the vehicles and horses were used to transport ice, and the soldiers of the Qi army were tired to death. The only good thing is that there are no casualties.

The next day, another day of ice attack. The ice cubes that were thrown into the city yesterday were removed by the Western Xia army overnight. Otherwise, once the Qi army attacked the city, with these ice blocks, the sergeants would not be able to go up to the city wall to support.

The ice cubes were thrown for three days in a row, beating the Western Xia army to a grievance. Later, the Western Xia army also thought of this method, and planned to use the other way to return the favor to the other. Ice thrown into the city was collected, watered, and melted into ice balls. It's just that these pucks aren't useful yet. Because the freezing time is too short, it will not be firm when it melts together. Unlike the ice carved out by the Qi army, it has been frozen for nearly a month since the beginning of winter.

On November 23, the ice thrower worked for a whole day until it was completely dark. At this time, a team of more than 60 people took advantage of the night and the sound of gongs and drums to sneak into the lower ice embankment and quietly touch the direction of the city gate.

The leader of this team is Zhang Bing. Dressed in thick cotton clothes and wrapped in cloth around their heads, they crawled slowly towards the city gates.

Maybe he was numb by the tossing of the Qi army, and he didn't even find this team. It took nearly half an hour for Zhang Bing to climb under the city gate. Soon, he untied four bamboo tubes from his body. Each bamboo tube is the thickness of an arm and more than two feet long. Then he took out a rope and tied the four bamboo tubes together. The rest of the soldiers also took out their bamboo tubes and ropes and passed them to Zhang Bing, who began to tie them up again. He was cautious for fear of making a noise.

After another half hour, all the bamboo tubes were tied together. A sergeant next to him handed over two more bamboo tubes, and Zhang Bing opened the stopper and poured two balls of liquid on them.

At this time, behind the ice embankment, a group of troops stood quietly, and the atmosphere was not breathing.

Xin Qijian climbed onto the ice embankment and looked at the direction of the city gate with a solemn expression. Half an hour later, when Zhang Bing led people back again, Xin Qiji said lightly to Xin Yu beside him, "Behind the order, raise the fire." ”

Soon, the Qi army lit up the torches. The skyrocketing fire behind the ice embankment immediately attracted the attention of the Western Xia defenders on the city gate, who loudly warned the sergeant. The Western Xia army, which had been tortured by the ice thrower for a day, barely bred up and prepared for a night battle with the Qi army.

However, before they could fully react, two flames suddenly appeared on the ice bank. Xin Qiji and Xin Yu, father and son, each holding a rocket, stood proudly on the ice embankment.

"Quick, quick, shoot those two guys!" The guards of the Western Xia army shouted loudly, and the abnormal behavior of the Qi army made the guards of the Western Xia feel a trace of bad breath.

At this moment, Xin Qiji immediately opened his bow and shot the bow and arrows with a bang. The rocket hit the city wall and began to fall, and the fire illuminated the direction of the city gate. Immediately afterwards, Xin Yu's arrow also shot out, and with the rocket shot by his father, he suddenly saw the bamboo mountain that was piled together by nearly 200 bamboo tubes.

With a snap, the rocket was stuck on the bamboo mountain, and the bamboo tubes drenched in fire oil burst into flames at once.

At this time, the arrows of the Western Xia defenders came out, and the Xin father and son turned over and slipped down the slide behind the slope, blocking their ears.

A moment later, I heard a violent loud bang, like several thunderbolts at the same time, setting off a loud bang. The ground beneath his feet shook violently, and even the solid ice wall made a clicking sound.

The Xin father and son were shaken by the shock, and the sergeants behind the ice embankment sat on the ground in unison, everyone trembling, dizzy, and their ears buzzing, as if they were about to faint.

The power of six or seven hundred catties of gunpowder is really extraordinary. These gunpowders were all the gunpowder in the Daqi military camp, and they were all packed into bamboo tubes and put at the city gate in one go. In fact, the ice embankments on the other three sides of Chang'an City were only confusing and deterring, in order to cover the blasting.

Thanks to the blocking of this ice embankment, otherwise, I don't know how many Qi troops would have been injured by this huge explosion.

With a whoosh, a piece of something fell from the sky and landed in front of Xin Yu, startling him. After seeing clearly that the thing turned out to be a green brick, Xin Yu was overjoyed, "The city is broken, brothers, hurry up." ”

As soon as he finished speaking, the huge drum behind the army was beaten, which was the signal to march. All the Qi troops immediately divided into three groups, two of which bypassed each side of the ice embankment, and the middle group climbed over the ice embankment and rushed towards the city gate.

Xin Qiji and Xin Yu climbed back onto the ice bank and looked ahead. The scene in front made the two of them staggered, and the entire city wall of more than ten zhang to the left and right of the city gate was all blown down, becoming a huge gap. Countless fire dragons poured towards the gap, and on the city walls on the left and right, the Western Xia army was directly shocked to death by the huge explosion, and more than a hundred soldiers were killed, and the others were still lying on the city wall wailing.

Inside the city wall, due to the merits of the ice throwers during the day, the Western Xia army that was hiding outside the range of the ice throwers did not have time to rush to the gap to block it.

Chang'an City is broken, just tonight!

"Father, if there were no explosives, how would you break this fortified city?" Xin Yu shook his head, which was still dizzy, and asked the question that had been hanging in his heart for a long time.

Xin Qiji smiled bitterly, "Then there is only one stupid way, and that is to pour the ice and snow forward, and push the ice embankment forward little by little until it is pushed under the city wall." It's just that it took more than two months to do that. Until the beginning of spring next year, whether it can be piled up under the city is still a question. And we, we can't wait that long. ”
