Cheng Yaojin had this idea, so the first few defeats did not shake his confidence at all. Although the Tang Dynasty was a long expedition, the materials were much more abundant than Anshicheng. Moreover, they had seized a large amount of materials before, which made him unscrupulous when siegeing the city. The siege equipment was burned, so the craftsmen seized the time to make a batch.

However, in this way, the siege battle became very boring. The Tang army almost repeated the attack, blocked, retreated and other steps. There was not much casualties in one day, but there was no progress. It was just to consume a large amount of supplies in Anshicheng. For example, on the second day, Li Xiu discovered that Anshicheng no longer used tincture oil as recklessly as the first day. Instead, it only used tincture oil to ignite fire at critical moments to burn the Tang army's siege equipment. This also shows that there is not much reserve of tincture oil in the city.

In fact, the materials in Anshi were still very sufficient, but no matter how sufficient the materials were, it could not withstand the repeated attacks of the Tang army, and it was also obvious that it would consume the materials in the city. This made Yang Wanchun have to order to save every piece of materials as much as possible. After all, it is only summer now, and it will take at least three or four months before Liaodong becomes cold. With the materials in the city, it may not last for so long. However, even so, he did not intend to give up. After all, defending the city is not just about competing for supplies. Persisting to the end, it is also about competing for the will and determination of both sides.

The continuous attacks have consumed a lot of materials in Anshicheng. No matter how much Yang Wanchun saves people, by the third day, the most important tincture oil has been consumed, and even not much wood-rolling stones are available. For this reason, Yang Wanchun has sent someone to demolish some useless buildings in the city, and transported the bricks and stones to the city for later use.

However, in comparison, tincture oil poses a greater threat to the Tang army. After all, the equipment for siege is made of wooden, so it is most afraid of fire. Now that the tincture oil is gone, the biggest threat to the Tang army is less. This also allows Cheng Yaojin to finally be assured and bold assault. Moreover, he had promised Li Shimin that he would capture Anshi City within three days, which is the last day today.

"Dongdongdongdongdongdongdongdong~" With the tight sound of war drums, another round of siege was about to begin. Li Shimin, Li Xiu and others also came to the battlefield to look at the battle again. After all, this is Cheng Yaojin's real siege battle, and whether Cheng Yaojin can fulfill his promise is here. However, Li Xiu was also very nervous at this time, because he always felt that Cheng Yaojin might suffer a big loss.
