"Put!" With the order of the head of the city, the trebuchets gathered from the four city walls also bounced off immediately, and one by one the stone bullets roared out, smashing into the Tang army in front of the city with the momentum of ten thousand jun, although the formation of the Tang army was very scattered, but there were always a few unlucky eggs who would be touched, and the result was either death or injury.

However, compared with the huge number of Tang troops, the role of those trebuchets at the head of Anshi City is too limited, and the Tang Army is not to be outdone, and also transported a lot of trebuchets, and the Tang Army is not ordinary stone bullets, but oil bombs and gunpowder bombs, and also specializes in attacking the trebuchets of Anshi City, so it is often the trebuchets of Anshi City who just threw out a few stone bullets, and were hit by the Tang Army's oil bombs or gunpowder bombs and finally burned into a pile of torches.

The trebuchet is not a too complicated instrument for the Tang Dynasty, and even the craftsmen in the army can build it with local materials, but Goguryeo is a semi-nomadic people, and the domestic technical level is low, so the trebuchet is not easy for them to manufacture, and the range and accuracy are not as good as the Tang Dynasty, and there is a lack of wood and craftsmen in the city of Anshi, so the trebuchet on the head of the city is also one less than one destroyed.

But even so, Yang Wanchun did not waver in the slightest, even if the trebuchet was burned out, he had to try his best to stop the Tang army's strategy of building a mountain, otherwise when the earth mountain was built, it would be the day when their city was broken, and it would be useless to keep more trebuchets at that time, so he transferred all the available trebuchets in the city, and there were also a large number of arrows, in the past two days, they were almost crazy and desperately attacked downward, and the arrows on the ground were densely lined up, looking like crops.

When it was almost dark, Yang Wanchun thought that the Tang army would build a mountain like yesterday, but he didn't expect the Tang army outside the city to retreat slowly, leaving a mound that had been piled up several zhang, although there was still some distance from the city wall, but as long as the Tang army unswervingly moved forward to fill the soil, sooner or later it would come into contact with the city wall, and then the Tang cavalry would come straight to it, and the city head would definitely be lost.

After two days of mountain building in the two prefectures, the Tang army actually retreated, and it seemed that the Tang army also had to rest, which also made Yang Wanchun breathe a sigh of relief, but when he saw the earth mountain outside the city that was almost level with the city wall, he couldn't help frowning, even if the Tang army had retreated, but there was still a Tang army stationed on the earth mountain, it seemed that it was to prevent them from occupying the earth mountain, in fact, Yang Wanchun really had this idea, but he thought that he had to send troops out of the city to occupy the earth mountain, and he immediately dispelled this idea, after all, now he sent troops out of the city can only find death.

Thinking about the progress of the Tang army's mountain construction in the past two days, it is estimated that it will take another five or six days to make the earth mountain and the city wall come into contact with each other, which makes Yang Wanchun's brows wrinkle even tighter, but in the face of this situation, he has no choice but to shake his head and order people to clean the city, and let people replace the defenders of the city, in fact, because of the high-intensity combat during this time, the defenders on the city head have to be rotated almost every few hours, otherwise they will not be able to hold on at all.

"Father, it's been two whole days, the Tang army has been building dirt mountains outside the city continuously, and we have been constantly obstructing, but the material consumption in the city is really amazing, especially the trebuchet has been destroyed by half, and the arrows have also consumed three or four percent, if it goes on like this, I'm afraid we won't even be able to shoot an arrow in a few days." As soon as Yang Wanchun got out of the city, his son Yang Pet stepped forward with an anxious face and spoke.

"No matter how big the consumption is, we must hold on, otherwise we can't watch the Tang Army fill in the earth mountain on our city wall!" Yang Wanchun sighed at this time and said, the Tang army is a yang strategy, and he crushes himself with dignified strength, after all, whether it is in terms of manpower, material resources or financial resources, the Tang army is far superior to his side, it can be said that if he has no accidents, he has no chance of winning at all.

Yang Pet didn't know his father's hardships, especially when he saw his father's frowning appearance, he felt even more uncomfortable, but he still had more important things to report, so he could only cheer up again and said: "The consumption of materials is not enough, the key is that the soldiers who defend the city are already exhausted after two days of rotation, although the soldiers respect their father, but if they continue to work so hard, I am afraid that sooner or later there will be complaints in the army, and then the army will be unstable, and the situation will be even worse!" ”

Hearing his son's words, Yang Wanchun couldn't help but show a solemn expression, in order to prevent the Tang army from building mountains in the past few days, he had ordered the defenders of the city to take turns, but because the intensity of the battle was too great, the soldiers were also very tired, which was indeed a problem, and it might even lead to the soldiers being tired of war, and it would be even worse.

"Tomorrow, let the soldiers at the head of the city have a good rest, and deploy the reserves in the city to the head of the city to rotate!" Yang Wanchun thought about it for a while, and finally spoke.

Yang Wanchun is good at defending the city, and every time he defends the city, he is used to preparing a team in the city, mainly to prevent any accidents from occurring, and then this team can achieve the purpose of remediation, in fact, his reserves are the elite of the city, and the reason why Cheng Yanjin failed to take down Anshi City before, his reserve team played a key role.

"This ...... Is it really necessary to use the army of reserves? Yang Pet couldn't help but hesitate a little when he heard this, the number of reserves in the city is also quite large, reaching about 10,000 people, and all of them are elites, and they will generally only be used when the life and death of Anshi City are at stake.

"Now is the moment of our life and death, I expect that the Tang army will definitely continue to build mountains tomorrow, although our obstruction effect is limited, but at least it will also bring some casualties to the Tang army, if the Tang army's casualties are too large, I think the Tang emperor should reconsider the method of attacking the city!" Yang Wanchun immediately spoke again.

However, when talking about the above, Yang Wanchun did not have any confidence in his heart, because he knew that His Majesty the Emperor of the Tang Dynasty was not an ordinary person, and he was also a battle-hardened commander when he was young, such a person may not care about temporary casualties at all, after all, as long as he conquers his own Anshi City, he can quickly raid Pyongyang City, and if Pyongyang City is lost, then the entire Goguryeo will be over.

Yang Pet heard his father's words, and could only nod helplessly, and then helped his father home, in fact, Yang Wanchun has been staying in the city for the past two days, eating and living with the soldiers, but he has too many things to worry about, so he didn't sleep much at all, and now the whole person looks extremely haggard, and his cheeks are sunken, which makes him worry about whether his father's body can hold on?

Yang Wanchun is indeed extremely tired, back home just a few mouthfuls of food, already sitting on the chair asleep, and finally Yang Pet personally helped him to the bed to rest, this night Yang Wanchun also slept very deeply, but the next day before dawn, he was awakened by the sound of war drums outside the city again, immediately jumped up and put on armor and ran to the city, sure enough, found that the Tang army began to build mountains again.

After resting for a night, the Tang army's offensive became more ferocious, and Yang Wanchun found that the Tang army on the opposite side seemed to have changed a batch, and the generals who commanded the Tang army before had also changed, but the quality of this Tang army was no worse than the previous Tang army, and there was a great degree of law between advance and retreat, which made him sigh secretly, even if it was the most elite army in his hands, I am afraid it could not be compared with the Tang army on the opposite side, which is why he wanted to fight to keep the city wall.

However, although the Tang army is fierce, Yang Wanchun has also been prepared, especially today, the defenders of the city have been replaced by the army prepared in the city, and the morale is also very high, so when the Tang army attacked, the rain of arrows also brought some casualties to the Tang army, especially with the forward filling of the earth mountain, the Tang army is getting closer and closer to them, and it is easier for them to exert the power of bows and arrows.

It lasted until noon, and the Tang army outside the city also changed a few rounds, and Yang Wanchun on the head of the city also replaced a batch, after all, they spent much less effort to defend the city, but the Tang army outside the city carried the soil and mud, and they had to be careful of the arrows and boulders above their heads, they were much more tired than them, but the number of Tang troops was large, and they would change a batch when they were tired, and they were not afraid that no one was available.

"Father, lunch has been prepared, and the soldiers who have taken turns have already begun to eat, so go eat some too!" Yang Pet came to the city wall at this time, and then persuaded his father that he knew that his father had no time to eat when he was busy, and it was not a way to go on like this.

"No, you can just get me some dry food!" Yang Wanchun was standing at the battlement of the fortress and staring at the Tang army outside the city motionless, although the main task of the Tang army was to build a mountain, but at the same time it was also suppressing the bows and arrows at the head of the city, so the crossbows and trebuchets outside the city did not stop, so he had to hide in the fortress at the head of the city.

Hearing his father say this, Yang Pet had no choice, so he had to go down and let people get some dry food, and there was also a bowl of rice soup, Yang Wanchun was indeed hungry at this time, so he took the dry food and stuffed it into his mouth, and then poured the rice soup into his mouth and swallowed the dry food, saying that it was eating, but in fact it was swallowing, and it was estimated that eating was only a requirement for him to fill his stomach.

However, just as Yang Wanchun was about to swallow his lunch, he suddenly saw a soldier running over in a panic and shouting loudly: "Qiqi City Lord, there is a Tang army that 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 people are there on the other side, and how is the offensive?" ”

"There are about 20,000 people, the offensive is very fierce, and there are not many people in Nancheng, and now it is a little impossible to resist, and I ask the city lord to send reinforcements quickly!" The person who came to report the news also replied very anxiously, Nancheng is the main gate of Anshi City, and the last time Cheng Biting Jin blew up the city gate, there were originally the most defenders there, but because the Tang Army began to build mountains in the southeast corner in the past two days, the defenders on the south side of the city also transferred a lot.

"Boom~" As soon as the voice of the person reporting the news fell, he suddenly heard a huge roar from the direction of the south of the city, and Yang Wanchun's face was also pale with surprise when he heard this voice, because he had already heard this kind of sound last time.
