The Song army of Zhongjing Road calculated a lot of money. Is it a high cost to consume artillery to attack the city or send soldiers to attack? With the help of Su Shi, Peng Qi came to an amazing conclusion that the best way to deal with the strong city of Dading Prefecture is not to use soldiers to attack, but to consume ammunition to bombard the bombardment.

Zhao Zhen once calculated that it was more cost-effective to use soldiers to attack the city at that time. Gunpowder only made it easier for soldiers to open the city. But today, unlike in the past, the national strength and military strength of the Song Dynasty had already reduced the cost of gunpowder, and cast iron shells would not be so extravagant.

So Peng Qi decisively adopted Su Shi's strategy and mobilized all the artillery of the East and West Route Army. He is now the supreme commander of the Song army of Zhongjing Road. When Zhao Zhen changed the target to Zhongjing Road, he gave Peng Qi a new dispatch, the general manager of the Zhongjing Road marching.

Although the name of this delegation is not conspicuous, it has great power. He has the right to mobilize all the Great Song army and armor in Zhongjing Road, including materials, so it is not difficult to call cannons.

The ratio of artillery among the various armies of the Song Dynasty was different, but there were some. The only one without artillery was Yang Huaiyu's Beiwei Tabai Army, but they carried a considerable number of gunpowder bullets, which were tied together in large quantities and became amazingly powerful explosives.

In a sealed environment, the power generated by the explosion is much stronger than being thrown directly into the enemy. So in order to assist the army in destroying the Dadingfu wall, Yang Huaiyu selected hundreds of elite cavalrymen. They carried explosives and rushed towards the wall under the cover of the large army artillery, and placed explosives at the fastest speed for blasting missions.

Hundreds of artillery fired at the Dading Mansion's city walls at one go, and five firings were fired every half hour. This was the limit of the use of artillery in the Song Dynasty. In order to cool the cannon chamber, the craftsmen in the army thought of an extremely effective method, sew a cover with waterproof tarpaulin, put it on the cannon after filling it with water.

At the beginning, the water vapor in these water covers heated by artillery broke the tarpaulin, and the boiling water burned many people. However, afterwards, the craftsmen concluded that a frame should be set up in the tarpaulin and then holes should be opened at the top and bottom. The holes at the top are used to remove water vapor and inject water, and the holes at the bottom are used to release hot water.

This accelerates the firing speed of the artillery, but increases the installation time of the artillery, but one of them must be chosen. In the case of having the advantage, this kind of water-cooling is naturally adopted. After all, the cannon steel of the Song Dynasty did not reach the level that can be air-cooled.

The city wall of Dading Mansion is like a crumbling tower, with wall tiles falling constantly. This is based on the design of the Dasong city wall. The wall is built with rammed earth inside and wall tiles outside, which has a certain impact resistance. However, once the wall tiles outside fall and the rammed earth is exposed, it will become fragile under the powerful impact force.

Peng Qi knew that he had not had much time. The Kuaima who came from Beijing had already brought Zhao Zhen's "Eight Character True Words" to him. If he could win the Dading Prefecture within a period of time, it would increase bargaining chips for the negotiations between Song and Liao.

And he, Peng Qi, is a great hero, and can even be famous in history, not inferior to Di Qing! Who doesn’t want such a name?

So Peng Qi ordered the soldiers in the army to increase the number of gunners. Although the number of artillery could not be increased, the increase in the number of gunners could cause the Song army to bombard the city walls of Dading Mansion day and night.

In addition, the elite cavalry sent by Yang Huaiyu as the blaster, the city wall of Dading Mansion was shaking and finally collapsed on a large scale under the attack of one day and one night. This was not the collapse of the city walls that had appeared before, but the collapse of the entire city wall.

Dading Prefecture was built on the alluvial plain of Laoha River. It has Qijin Mountain in the north, overlooking Mayu Mountain in the west and Laoha River in the south. Decades ago, the climate here was mild, with abundant water and grass, which was suitable for farming and grazing. It was built when the Liao Dynasty was the most prosperous, and the city was magnificent.

Because it was built in the Tokyo Bianliang of the Song Dynasty, the outer city was 4,800 steps long from east to west and 3,500 steps wide from north to south; the inner city was 2,000 steps long from east to west and 1,500 steps wide from north to south, and the inner and outer cities were built in the shape of "hui".

The artillery bombarded the outer city, and the collapsed Zhuxiamen, the south gate, which suffered the strongest firepower. The urn city outside Zhuxiamen had disappeared and had no effect on its trapping of the enemy.

When the tall Zhuxia Gate collapsed, the great Song army sent a shocking cheer, and the soldiers raised their hands to celebrate and shouted loudly. However, the soldiers and civilians in Dading Mansion were shocked by the scene in front of them. The tall and majestic Zhuxia Gate collapsed. This was not a part of the collapse of the city gate, but a whole wall of thousands of steps collapsed.

The garrisons under the city flocked back, and huge smoke and dust floated in the air to cover the sky. It seemed like the earth-shaking end of the world was coming. Countless screams and horror sounded, and Yelu Pei smiled at the sky and said, "The sky destroyed my great Liao!"

The collapse of Zhuxiamen was a turning point in the battle between Zhongjing Road in Song and Liao, and also meant that the defenders of Zhongjing Road in Liao Dynasty completely lost a barrier.

The rumbling cannons of the Song Dynasty stopped, and then countless crossbows like iron guns shot into the city. The damn flyers rained again. This time the content was not just about persuading surrender, but about a naked threat.

When the Song Dynasty had an absolute advantage, Peng Qi felt that Su Shi's softer leaflets should have changed, first rituals and then soldiers, and it was time to threaten the military and civilians in the city with sharp words. In the face of the Song Dynasty, it was like a collapsed Zhu Xiamen, and it was gone!

Just when the soldiers and civilians in Dading Prefecture were frightened and hesitant, the sound of artillery sounded again, but this time it was no longer from the south, but from the east and west sides. Sima Wang He, a marching army in the four armies, suggested to Peng Qi to bombard the city walls on the east and west sides of Zhongjing Road again, but left the north side...

Because the city walls on the north have no need to attack, and they will become an obstacle to the evacuation of the Liao army!

Wang He and Wang Gui successfully persuaded the Han family to surrender on the eastern front, and asked Peng Qi to look at them differently. Now he has made suggestions and naturally adopts them. He also feels that this method is the best.

Yelu Pei in the city had already placed the army into the inner city, the imperial city. He had no choice. The turtle shell of Dading Prefecture in front of him had been broken by the Song people. Only the last layer of protection could protect them from the artillery fire of the Song army, but the people in the city had already begun to flee.

The number of people and the number of people made Yelu Pei unable to resist, and he did not dare to let the soldiers suppress him anymore, because such a conflict would be harmful to the army and would only make the Liao army more serious internal friction.

Because of the collapse of the Nancheng City, shells fell into the city from time to time, and once they were hit, they would be killed or injured.
