"Let it go!" With the order from the city, the catapult gathered from the four walls immediately bounced away, and stone bullets roared out, and smashed hard into the Tang army that was building up in front of the city with a tremendous force. Although the formations of the Tang army were very scattered, there were always a few unlucky guys who would be touched, and they would either die or be injured.

However, compared with the large number of Tang troops, the functions of the stone catapults at the city entrance of Anshi were too limited, and the Tang army was not to be outdone, and they also transported many stone catapults. Moreover, the Tang army did not use ordinary stone bombs, but turbulent bombs and gunpowder bombs, and they also specifically attacked the stone catapults in Anshicheng. Therefore, it is often that the stone catapults in Anshicheng just threw out a few stone bombs, and were hit by the Tang army's turbulent bombs or gunpowder bombs and were finally burned into a pile of torches.

For the Tang Dynasty, the trencher was not a very complicated equipment. Even the craftsmen in the army could be built locally from materials. However, Goguryeo was a semi-nomadic people and the domestic technical level was low, so the trencher was very difficult to make for them, and the range and accuracy were not as good as the trencher. There was a lack of wood and craftsmen in Anshi City, so the trencher on the top of the city was also destroyed and one less was lost.

But even so, Yang Wanchun was not shaken at all. Even if the catapult was burned out, he had to try his best to stop the Tang army from building the mountain. Otherwise, when the earthen mountain was built, it would be useless to keep more catapults at that time. So he transferred all the catapults that could be used in the city, and there were also a large number of arrows. In the past two days, they were almost crazy and attacking downwards. The arrows on the ground were lined up densely, looking like crops.

When it was almost dark, Yang Wanchun thought that the Tang army would build mountains in the mansion like yesterday, but he did not expect that the Tang army outside the city would retreat slowly, leaving behind a pile of soil that had been piled up several meters. Although it was still a distance from the city wall, as long as the Tang army unswervingly moved forward to fill the soil, it would sooner or later come into contact with the city wall. At that time, the Tang army cavalry rushed straight to the front of the city, and the city would definitely be lost.

After two days of building mountains in two mansions, the Tang army retreated. It seemed that the Tang army was going to rest for a while, which also made Yang Wanchun breathe a sigh of relief. However, when he saw the Tushan Mountain outside the city, which was almost level with the city wall, he couldn't help but frown. Even though the Tang army had retreated, there was still a Tang army stationed on the Tushan Mountain. It seemed to be to prevent them from occupying Tushan Mountain. In fact, Yang Wanchun really had this idea, but when he thought that he had to send troops out of the city to occupy Tushan Mountain, he immediately gave up this idea. After all, now he could only seek death.

Thinking about the progress of the Tang army building the mountain in the past two days, it is estimated that the earthen mountains and the city walls will be brought into contact with each other in five or six days. This made Yang Wanchun's brows even tighter. However, in the face of this situation, he had no choice but to shake his head and ask someone to clean the city and replace the defenders at the city. In fact, due to high-intensity combat during this period, the defenders on the city would have to take turns every few hours, otherwise they would not be able to hold on.

"Father, it's been two days since the Tang army has been building soil mountains outside the city. We have been constantly obstructing it, but the consumption of materials in the city is really amazing, especially since most of the catapults were destroyed, and the arrows were consumed 30 to 40%. If this continues, we may not even shoot an arrow in a few days." As soon as Yang Wanchun hit the top of the city, his son Yang Chong walked forward with anxiety and spoke.

After resting for a night, the Tang army's offensive became even more fierce. Yang Wanchun found that the Tang army opposite seemed to have changed a group, and the generals who had commanded the Tang army before also changed. However, the quality of this Tang army was no worse than that of the previous Tang army. There was great rules between advancing and retreating, which made him sigh inwardly. Even the most elite army in his hands might not be able to compare with the Tang army opposite. This is also the reason why he fought to the death and wanted to protect the city wall.

However, although the Tang army was fierce, Yang Wanchun was prepared, especially today, the defenders of the city were replaced by the prepared army in the city, and their morale was also very high. Therefore, when the Tang army attacked, the rainy arrowheads also brought some casualties to the Tang army, especially as the earth mountain moved forward, the Tang army became closer and closer to them, making it easier for them to exert the power of bows and arrows.

It lasted until noon. The Tang army outside the city also changed several rounds, and Yang Wanchun on the top of the city also replaced a group. After all, they spent much less effort to defend the city. On the contrary, the Tang army outside the city carried mud and had to be careful of the arrows and huge rocks above their heads. They were much tired than them. However, the Tang army was more numerous, so they changed a group when they were tired, and they were not afraid that no one could use it.

"Father, the lunch has been prepared. The soldiers who have been replacing have started eating. You can go and have some too!" Yang Chong came to the city wall at this time and persuaded his father. He knew that his father had no time to eat when he was busy. This was not a solution.

"No, just get me some dry food!" Yang Wanchun stood at the fortress and stared at the Tang army outside the city motionless. Although the main task of the Tang army was to build mountains, it was also suppressing the bows and arrows on the top of the city, so the crossbows and catapults outside the city never stopped. For this reason, he had to hide in the fortress on the top of the city.

Hearing his father say this, Yang Chong had no choice but to go down and get some dry food, and there was also a bowl of rice soup. Yang Wanchun was indeed hungry at this time. He immediately put the dry food into his mouth, and then poured the rice soup into his mouth and swallowed it with the dry food. He said that it was eating, but in fact it was swallowing. It was probably only the requirement for him to eat to fill his stomach.

But just as Yang Wanchun was about to swallow his lunch, he suddenly saw a soldier running over in panic and shouting: "Report to the city lord, a Tang army has begun to attack Nancheng!"

"What?" Yang Wanchun couldn't help but show a shocked expression when he heard the news, and then asked, "How many troops does the other party have and what's the offensive?"

"There are about 20,000 people, and the offensive is very fierce. Moreover, there are not many people in Nancheng, so I can't resist it now. Please send reinforcements as soon as possible!" The person who came to report the news also replied anxiously. Nancheng is the main gate of Anshi City. Last time Cheng Yaojin blew up the city gate. Originally, there were the most defenders there, but because the Tang army began to build mountains in the southeast corner in the past two days, many defenders on the southeast side of Nancheng were also transferred.
