"Roar up!" As a general shouted, rows of soldiers carrying the ladder rushed under the city wall, then erected the ladder by the wall and began to climb up desperately. The Goguryeo soldiers on the top kept pushing the ladder from the city wall with a special long rod. However, because there were too many ladders, even if one was missing, there would be a lot of soldiers from the city wall.

What's even more terrifying is that Cheng Yaojin used almost all the useful siege cars this time. Trees were standing beside the city walls. These siege cars were tall and heavy and could not be pushed away at all. Even if they were shot with crossbows or smashed with stones, it would be difficult to destroy these sturdy siege cars. The only way was to burn them with fire. However, the siege cars were almost used up before, and the siege cars were poured water in advance, and there was no sieve oil at all. As a result, the soldiers of the Tang army kept climbing to the top of the city and had already opened up sections of battlefields on the top of the city.

"It seems that Zhijie did not brag. Maybe we can go to Anshi City to have dinner tonight!" Li Shimin, who was watching the battle from a distance, also said with a smile. He did not expect the attack to be so smooth. When Cheng Yaojin pushed all his troops up, the Goguryeo people on the city of Anshi City gradually became dissatisfied, and now they have shown a defeat.

"There are no reinforcements outside and no supplies inside, I'm afraid anyone wouldn't be able to hold on!" Li Ji nodded in agreement at this time. He had been carefully observing the situation on the city from the telescope since he had just passed the telescope. Now he felt that Cheng Yaojin was almost sure to win, and Anshicheng was almost in their hands.

Li Xiu frowned when he heard this. Although on the surface, the Tang army did have an advantage. It can even be said that Anshicheng is facing the danger of the city being destroyed, but he always feels something is wrong. After all, Anshicheng can block Li Shimin's tens of thousands of troops in history. No matter how the Tang army attacks, it cannot be defeated. How could it be so easily broken?

Just when Li Xiu was confused, he suddenly heard a hustle and bustle on the top of Anshi City. Li Shimin and Li Ji, who were observing the top of the city, also exclaimed, which made Li Xiu hurriedly raise his telescope to watch. As a result, a group of Goguryeo elite soldiers rushed from somewhere on the top of Anshi City. They were holding tinder tanks in their hands, constantly igniting them and threw them on the siege car. In the blink of an eye, the siege car was burned into a large torch, and the soldiers attacking the city immediately turned into rootless water, and they couldn't escape even if they wanted to.

"I've been trapped!" Li Ji couldn't help but exclaim when he saw this. He didn't expect that Anshicheng opposite deliberately set up a trap, making them think that the turbid oil in the city had been used up. As a result, at the most critical moment, he took out the turbid oil, not only burned the siege car, but also trapped the soldiers who were attacking the city at the top of the city.

Li Shimin's face was gloomy when he saw this, especially when he saw that the soldiers who had already attacked the city were wiped out bit by bit, and then the body was thrown off the city, his face became worse. Li Xiu, Li Ji and others also kept silent at this time. After all, there was no need to touch Li Shimin's bad luck at this time.

As the soldiers attacking the city were about to be destroyed by the Goguryeo people, they suddenly heard a loud "rumbling" sound from the city gate. As a result, there was a cloud of smoke and dust at the city gate. I couldn't see clearly what was going on there. I could only hear the screams of countless Goguryeo people coming from the smoke and dust.

"That's great, General Cheng has finally used gunpowder!" Li Daozong was young after all, and he finally couldn't help but scream. The explosion at the city gate was caused by gunpowder, and it was a very rarely used siege tube. The so-called siege tube was actually a huge tube containing hundreds of kilograms of gunpowder. It was usually only used to blow up the other party's city wall or city gate, and its power was amazing.

"Zhijie is really calm and he has not used it until now!" Li Shimin saw the changes on the battlefield again, and it was beneficial to his side. His face became much better now. He even found that the Goguryeo soldiers on the top of the city were already scared. This gave the Tang army soldiers trapped at the top of the city time to gather together and then rushed to the explosion place desperately, because they knew that the brothers below would definitely not miss this opportunity to rush up the top of the city, and then they would have reinforcements.

As a gust of south wind blew, the smoke and dust caused by the explosion slowly dissipated. At this time, Li Xiu and the others discovered that the gate of Anshi City had disappeared, and replaced by a collapsed city wall. It seemed that Cheng Yaojin must have used more than one siege tube, otherwise such great damage would not have been caused.

The city gates were all blown up, which made the Tang army, whose morale declined due to the burning of the siege cars, ignited hope again. At that moment, countless Tang army soldiers rushed towards the collapsed city wall, and the Tang army soldiers trapped at the top of the city also fought to death and began to clear the road for the brothers below.

Generally, when the city wall collapses, even the city is strong, it cannot be defended. Moreover, Cheng Yaojin commanded the Tang army to kill the gap at the city gate like a tide. He was about to rush into the city, and the army on Li Shimin's side was also prepared. As long as he could defend this gap, the reinforcements behind would attack in large numbers, thus capturing the Anshi City in one fell swoop.

However, just as the Tang army rushed to the gap, a wave of Goguryeo soldiers suddenly emerged from the city. These Goguryeo people also knew that life and death were in this way, so they were even more heroic than usual. Even if they died with the Tang army, they would not take a step back. At this time, Goguryeo soldiers from other places also reacted and rushed along the city wall. For a moment, the two sides started a cruel battle on the ruins of the city gate.

The gap in the city gate that was blown up was not very big. It looked about twenty or thirty steps wide, and too many troops could not be expanded at all, so it became a battleground for elite soldiers. Often, the Tang army finally killed all the Goguryeo people gushing out of the city, thinking that they could occupy the gap, but then a lifeless Goguryeo people gushed out of the city, pushing the Tang army out again. The two sides were fighting in this narrow area, with dead bodies stacking up one layer on one, and finally hitting until it was almost dark, and the gap could not be taken down, and the corpses on the ground were about to block the gap.
