The war drums were beating inside and outside Shanhaiguan, and artillery roared from the Weiyuan City. After a day of preparation, Sun Chuanting finally launched an attack.

The Yongsheng Dynasty army had a fixed pattern of siege in the city, which was to use artillery to open the city gate or sweep the arrow battlements and women's walls, and then rushed forward.

Sun Chuanting was no exception. At the beginning, he also used artillery to open the way.

However, the situation this time was a bit special, because Weiyuan City was located on the top of the mountain, which offset the range advantage of cannons. The defenders in the city could also fire their cannons against them, and the soldiers who controlled cannons were still in danger.

It can be said that this is the first time that the Crazy King Army has encountered artillery attacks.

Although they do not have high-precision telescopes, they cannot lock their specific positions at all. Moreover, the red-clothed cannon is extremely accurate and it is difficult to hit the cannon array that spreads into an arc, but there are also quite a few cannons. After one round, it is possible that they can hit the target for a few shots.

To this end, Sun Chuanting specially equipped each cannon with a siege car, and ordered people to transform the siege car, take down the wooden rafts blocking the front, and add it to the roof.

In this way, as long as the cannon siege under the cannon siege, there will be no danger for the soldiers who control the cannon. No matter how powerful the red cannon is, it is unlikely to blow away the wooden raft made of two layers of thigh-thick logs in one shot.

Sure enough, after several rounds of local runs and bombings, the artillery under the siege car was not damaged. Occasionally, a few shells hit the siege car, and basically they rubbed off a large piece of wood chips and then bounced away.

However, after Sun Chuanting carefully observed the banging effect with a telescope, his brows were no longer stretched. Due to the height, the effect of the pig iron solid bombing and the female wall was not very ideal. Generally, the shells would burst into a pit as big as a bowl and bounce it open.

This is obviously not possible. Although as long as the shells are enough, the battlements and female walls of the city wall south of Weiyuan City will be swept away sooner or later. The problem is that there is not enough time. The emperor is waiting for him to take down Shanhaiguan to meet. How long will it take to bombard like this?

He thought for a while and then ordered: "Tell me, change the shells, first bombard four rounds with armor-piercing shells, then bombard one round with explosion shells, then bombard one round with pig iron solid shells, and then bombard one round with explosion shells. This cycle goes on and on, rest for a quarter of an hour for every five rounds of bombardment, cool the barrels, and prepare the shells."

In this way, the effect is different. First of all, the armor-piercing bomb will not bounce. Although the armor-piercing bomb is not as big as the solid cast iron bomb, it is better than the drilling depth. After the armor-piercing bomb drills out of several deep pits, the solid cast iron bomb will smash it again, and the effect is not ordinary.

The subsequent round of explosive bombs is the finishing touch, because the targets of armor-piercing bombs and solid pig iron bombs are arrows and women's walls, even if they are smashed, they will basically not be injured. Because the defenders on the walls will lie down to avoid the shells, and the explosion bombs will be different, and it is useless to avoid them. Leaning down can only ensure that the front is not injured, and the back will also be filled with broken iron pieces.

Of course, if there is a shield, you can still resist it. As long as you use a shield to block the front of your body in the corner of the nest, you will not be sputtered by broken iron.

Therefore, only the first round of explosion bombs had the best effect, and the defenders on the city wall behind also reacted. Every time the roar of artillery sounded, they would quickly drill into the corner and block in front of them with shields.

However, even so, they were tortured. You should know that it is troublesome to load the red cannon. They also have to be wary of the enemy from time to time to prevent them from suddenly sending a round of explosive bombs. If they are accidentally stabbed, they will have broken iron pieces on their backs. How can they fight back?

The roar of cannons on the city wall was getting less and less. At the back, only a few cannons were still holding on, and the others were almost gone.

However, after one day, there were not many arrows cut off on the walls south of Weiyuan City, and there were not many gaps blasted out on the female wall.

The power of the shells was indeed greatly reduced by five or six miles away. It would take at least three days to flatten the battlements and female walls of the south wall of Weiyuan City.

Sun Chuanting raised his telescope to look at the situation on the city wall, looked up at the sky, and then ordered decisively: "Telection, the artillery keeps the formation, take turns to rest, and fire a round of explosive bombs every half hour. The First Legion, Second Legion and Third Legion of the Huguang Army took turns to arrange for warning to protect the artillery, and each legion is on duty for two hours."

This means you have to continue doing it at night!

The defenders in Weiyuan City didn't know that the Crazy King Army was going to work with them all night. They couldn't see the situation opposite in broad daylight. When it was dark, they couldn't see anything clearly. They thought they were like them and started to take turns to rest.

Unexpectedly, half an hour later, a roar of cannons suddenly rang below.

This scared the defenders on the city wall. They tried their best to hide under the female wall. Unfortunately, the broken iron pieces of the explosion bombs were sputtered everywhere, and it didn't do much to hide under the female wall. This round of artillery fire alone injured most of the defenders on the city wall.

To be honest, they have no way to do this.

This black paint is so dark, what can they do?

Fire a fire and fight back?

Just kidding, they can't see anything, so where can they bang!

As for rushing out of the city and counterattacking at night, there is no need to think about it. Originally, there were only 100,000 defenders in Shanhaiguan. After Wu Sangui brought 50,000 elite troops, there were only 50,000 new soldiers left here. The army of Crazy King attacked on both sides was 250,000, and there were 150,000 on the south side alone. They rushed out to attack sneakily, which was simply seeking death.

That night, the defenders on the city walls were even worse than during the day. The roar of cannons from time to time was like a death urging, which made them frightened and panicked all day long. After the shells fell, they were even more deadly. Unless they quickly shrank in the corner and blocked them with shields, they would be injured by the splashing iron pieces.

Who always holds a shield when you have nothing to do!

Is that heavy thing good?

If you take a look at it all night, people will be exhausted. In the middle of the night, the defenders on the city wall will hide under the city wall.

They had no choice. It was better during the day, and the artillery bombardment of the Crazy King Army was still very regular. After four rounds of solid bombs, it was definitely a round of explosive bombs. They were still better off guard.

At night, the army of Crazy King was like a lunatic. They would come to shoot from time to time, holding a shield, exhausted people. If they didn't hold a shield, once the roar of artillery sounded, it would be too late for them to lift it. Who would have to endure this trouble?

The next day, there were still artillery roaring outside Weiyuan City, and the Crazy King Army didn't know where so many shells came from. They had been bombarded for a day and a night, and they were still endless.

The red-clothed cannons on the city wall have long been gone. Even if they still have ammunition, they dare not reload them, because the arrow piles have almost been flattened, and there are gaps everywhere in the women's wall. Not to mention loading ammunition, it would be good not to be killed by dense shells.

The day passed like this. At night, the Crazy King army was still like a lunatic. From time to time, burst bombs came. The defenders on the city wall were tortured and ran down the city wall early.

They thought the army of Crazy King was just like yesterday, harassed them for a while and prevented them from resting.

Don’t you know that at midnight, after a round of artillery bombardment, the 100,000 Huguang troops rushed towards Weiyuan City like ants. Half an hour later, another round of artillery bombardment, and the 100,000 Huguang troops had already rushed under the city wall.

The Weiyuan City is built on the top of the mountain. The city wall is extremely difficult to build, so it is naturally not much taller. Basically, as long as the two of them work together to get out with their own ladder, the others can easily climb up the city wall.

Tens of thousands of Huguang troops climbed up the city wall silently. After they issued the signal, the roar of artillery below stopped, and the defenders hid under the city wall until an hour later found out that they were abnormal.

Why has the roar of the cannon not sounded for so long?
