Sima Wang sent troops, of course, now he has an army of nearly 150,000 under his command, and it is impossible for them all to be crowded together. For this battle, his troop arrangements are as follows:

On the north bank of the Wei River, about 20 miles away from the north gate of Yixian County, Sima Wang personally led 30,000 Luoyang Chinese troops (mainly recruits) to sit in the town. This is the base camp of the Chang'an Corps.

Five miles west of Yixian and Anguo City, 10,000 Di soldiers led by Li Mu and Li Te's father and son camped on both sides of the Wei River. Sima Wang did not expect too much from the combat effectiveness of the troops along the way. But on the whole, among the various alien races, the Di people are relatively trustworthy, and there are more troops this time. Therefore, Sima Wang asked Li Mu and his son to defend one side alone, and their main task was not to attack the city, but to close Guan Yi's information transmission channel.

To the north of the Wei River, five miles east of Yixian, is the 50,000 army led by Xun Kai and Li Fu, which is the main force of this siege. Its composition is mainly based on the former Guanzhong Corps and the Bingzhou reinforcements. The main target of the attack is, of course, Yixian, where Guan Yi is located.

As for Anguo City on the south bank of the Wei River, Sima Wang arranged for Zhan Qing to lead an army of 20,000 to besiege it. This is not the main point of attack for the time being.

After that, the 5,000 cavalry of the bald department, still deployed on the south bank of the Wei River, was tasked with cutting off the grain route between Hanzhong and Anguocheng.

Ju'an led 10,000 cavalry, together with 10,000 cavalry of the Southern Xiongnu, and was the mobile force of this operation. At this stage, the main task is to ensure the smooth flow of grain routes, and the second is to move around the battlefield, so that Guan Yi will completely lose contact with the outside world.

There are more than 13,000 people, led by Sima Yong and Du Pre, who are in Chang'an. The organization of the people's husbands to carry out the transportation of soldiers' food, the transport and treatment of wounded soldiers and other work were all completed by this army - Du Zhen may be the most powerful military strategist in the Western Jin Dynasty on the historical plane. But at least for now, his military talent has not been discovered: the big neck disease has limited his body, and in this era when the world has not completely eroded, military generals still have to ride horses in battle. And Du Pre, who was unable to ride a horse, was not recognized by Sima Wang and others at least at this time.

All of the above troops, with the exception of Sima Yongdu's pre-detachment, set out on 25 January, and then arrived at their respective positions on 30 January. Completed the encirclement of the two cities of Yixian.

If it is said that when the troops were dispatched, looking at the unprecedented grandeur of the army, Sima Wang was still a little complacent. So when he arrived at the city of Yixian and Anguo, and circled around the walls of the two cities, the little pride in his heart quickly came to naught.

Is this Yixian? Are we in the wrong place? With such a high city wall, even Chang'an doesn't have it!

I know that Guan Zifeng has a thing that can quickly build a wall, and the country Jinjuan Cao is desperately probing, and he only knows that this thing is called cement. After mixing with water, it can be shaped at will and dries quickly, and the hardness is extremely high after drying. But you, Guan Zifeng, are too scary, right? It's as if you're in infinite supply of something so good. In addition to hardening the walls of the two cities, all kinds of odd-shaped cement piles were scattered at a distance of 300 paces from the city walls, so that the advance of the besieging troops of this army was very difficult.

There was no way, so Sima Wang had to order the armies to suspend the siege and give them more time to build all kinds of siege equipment. At the same time, soldiers were sent to clean the cement piles outside the two cities.

This time defending the city, Guan Da Sima's lazy illness flared up again. At the current stage, he didn't have the intention of going to the city at all, and handed over all the defense of Yixian County to Shi Huozai, the commander of the army.

In this era, because it is extremely difficult to disseminate knowledge, many people's path to success is based on family learning. Unfortunately, the Huo family's specialty is defending the city.

……

On the first day of February, Sima Wang's entire army was in place. In the afternoon of the same day, Xun Kai sent a small force of more than 3,000 people to the east gate of Yixian County to deal with the cement piles outside the city gate.

A small number of officers of the Jin army were released by Guan Yi after surrendering in the Battle of Yang'an Pass. So it's not the first time these officers have seen cement piles, and they know what to do with these guys.

"Qi Huo Changshi, the enemy army is digging outside the east gate along the foundation of the barrier wall we built."

"Hehe, these thieves have also learned to be obedient. Well, let them dig and tell me when they're two hundred and fifty steps from the wall. ”

"Whoa!"

So, under Huo Zai's order, the Shu Han army at the head of the city quietly watched the Jin army under the city digging the wall foundation hard, and then smashed the entire cement pile with difficulty, moved it away, and then filled the big hole dug up.

There is no doubt that this is a big and laborious project. On the afternoon of the first day of February, Xun Kai's vanguard only cleared a small part of the outermost cement piles.

The next day, Xun Kaijia sent 2,000 men. On the one hand, there is an increase in manpower, and on the other hand, the soldiers are gradually becoming proficient in moving bricks. As a result, the progress of the project has been significantly accelerated. But Huo Zai still didn't say anything.

On the third day, one of the fastest advancing troops of the Jin army entered the range of 250 paces in front of the city wall.

After shaking his neck very comfortably after learning from Guan Yi's appearance, Huo Zai asked the soldiers beside him, "Are the trebuchets ready?" ”

"If you go back to the long history, the ten trebuchets on the entire east side of the city wall, and the fifty trebuchets under the city wall are all ready."

"Good, then give the order, all trebuchet troops, adjust the throwing distance to a distance of two hundred and seventy steps east of the city wall, and fire three rounds of volleys!"

"Whoa! Huo Changshi has an order. Two hundred and seventy steps, salvo! ”

"Yes! East No. 1 trebuchet, ready! ”

"East 35 and East 50 are ready!"

"East Wall Ten, ready!"

"It's all there, launch!"

With this "launch", countless clanging sounds sounded up and down the city wall. The hammers of sixty trebuchets fell hard, and the pouch on the other side of the counterweight bar was forcibly thrown into the air. The stone projectile in the pouch was quickly thrown due to the strong inertia.

Under the city, a Jin soldier was desperately beating hard cement piles with a sledgehammer. In the winter, he had already shed his heavy robes and armor. The lean upper body was completely exposed to the cold winter air of the Guanzhong Plain. Even so, his forehead was covered with beads of sweat the size of beans.

Wiped the sweat vigorously, shook his right hand, and was about to hold the sledgehammer again when he started work. He faintly heard a whistling sound in the air. He looked up suspiciously, trying to find the source of the sound, but suddenly felt that the previously bright sky suddenly turned black.

Then, he felt the ground shake heavily, and the bare upper body, for some reason, suddenly had a layer of slimy, very warm liquid. Then a huge black shadow bounced high from the ground and flew away quickly......

After a while, he saw a mass of red and white meat sauce in his sight. Inside the meat sauce, there are sometimes some iron and cloth stuff mixed in. This is?

Soon, he finally came to his senses. Isn't the location of this mass of meat sauce the same as the location of his comrade-in-arms who held the iron chisel for him just now to facilitate his sledgehammer work?

So what was that huge black shadow just now?

Without waiting for him to think too much, the soldiers of the Jin army who reacted faster than him had already begun to howl hoarsely: "Enemy attack!" Trebuchet! ”

The soldier finally reacted completely at this time, and then his body didn't need his brain to issue an order, and immediately instinctively began to run towards the east - although he still couldn't understand why the enemy's trebuchet could hit so far, but there was no doubt that the farther away from the opponent's wall was at this time, the better!

He hadn't even taken a few steps when he heard the most cruel voice in his life: "Reload!" Prepare for a second volley! ”

Although more power poured out of his body again, his speed increased again. But where are the feet of man like a stone bullet that goes straight through the air? Soon, he heard the terrifying whistling sound in the sky again. Then there was another earthquake in the earth.

This time, he saw with his own eyes that a comrade who was seven or eight paces away from him was crushed by a jumping stone projectile from his back, and the whole stone bullet first rolled to the heel of the comrade and tripped over it, and then rolled along his back. On the whole land, there is a puddle of meat sauce in the shape of a vertical shape.

Before Huo had yet to carry out the third round of strikes on his side, the entire Jin army had already collapsed.

Seeing that the Jin army under the city had all collapsed, and there was no longer a dense formation like just now, Huo Zai shook his hand in a relaxed manner: "Order, stop the third round of shooting." ”
