Chisong Dezan's arrangements for the soldiers who siege the city were quite meticulous, and he would never exhaust the soldiers who siege the city. Basically, they would be replaced in more than two hours.

After experiencing a siege, it will be almost the next day when it is my turn, and the soldiers are still very relaxed.

The reason why he chose to do this was because Chi Song Dezan knew that Li Ren would not be foolishly waiting for him to break Yaozhou. He would definitely fight him to the death before he could not defend himself. Only by preserving his strength and waiting for that battle can he have a result.

However, what Chi Song Dezan didn't expect was that just when he was lying down, the group of people who were currently sieging the city were about to change their guards, and there was a movement at the north gate of Yaozhou City, which was the farthest from his location.

No matter which Tubo soldiers attacked the city, they would never have imagined that the door that had been tightly closed since they arrived would suddenly open itself in this dark night.

A Tubo soldier who was about to climb up the ladder was the first to discover this. At the beginning, he thought he was dazzled, but after rubbing his eyes, he found that he was not dazzled, nor was he dreaming, but actually saw that the north gate of Yaozhou City was opening.

"The city gate is open! The city gate is open! The city gate..."

When he shouted the third time, a sharp arrow suddenly shot out from the city gate, which penetrated his throat directly, but his shout was also heard by the Tubo soldiers next to him.

However, when several soldiers came around, suddenly, a whirlwind seemed to float out of the city gate, and cavalrymen rushed out, and wherever they passed were Tubo soldiers who were killed without any time to react.

This was an adventure, but Li Qing and Chen Zhibao bet correctly. The enemy did not expect that they would dare to open the city gate at this time, and they only opened the city gate for a small half. After that, Chen Zhibao took the lead and rushed out with his 20,000 troops. There were not many enemy troops attacking the city at this north gate.

When they came to their senses and sent some people to the tent to repay Chisong Dezan, Chen Zhibao had already run away with his men and disappeared into the darkness.

"What, a cavalry with a total of 10,000 or 20,000 people rushed out?"

When Chisong Dezan got the news, the cavalry had obviously rushed out. When he sent 20,000 troops to see, the north gate had been closed by the Tang army again.

The Tubo soldiers who were sieging the city obviously tried hard, but the cavalry had killed many of them in this rush, and the Tang army inside immediately began to close the city gate after the cavalry rushed out.

Although there were a hundred and dozens of Tubo people entering the city, they were quickly surrounded and killed, and the city gate was still closed.

After Chisong Dezan received the news, his brows frowned at that time.

He kept thinking in his heart, what was the dark and lantern, and what was the Tang Dynasty's sudden release of 20,000 cavalrymen to do?

Indeed, compared to the 300,000 army he brought out, these 20,000 troops were a drop in the bucket, but Li Neng would not do anything without reason. Chi Song Dezan was almost certain of this, so he understood that the real battle might be about to begin.

In fact, Chisong Dezan still didn't know Li Yan enough. His instinctive idea at this time was that most of the cavalry team had gone to the north to bring reinforcements.

After all, this place is not far from Quzhou, and the boundary he had drawn with Ge Luofeng before was in Quzhou. He had reason to believe that Li Ling might have set up a team of troops in Quzhou. This time, he wanted these cavalrymen to take those troops and then cooperate inside and outside.

After all, it is quite difficult to rely solely on these 20,000 cavalrymen to play a role, so Chisong Dezan did not think about these cavalrymen being able to sneak attack him.

Moreover, in their eyes, even if these cavalry attacked, they would definitely be attacking him, Chisong Dezan himself. In fact, he was looking forward to these people coming to attack him, because he had already made various arrangements in front of him.

However, what Chisong Dezan never expected was that Chen Zhibao, who had disappeared into the dark night almost as soon as he left the city, rushed directly to the camp of the 10,000 cavalrymen like a ghost in this dark night.

As Tubo cavalry, they are actually much stronger than the initial siege. At least they rarely need to go on the field in this siege. They only need to do their own work well, and in this process, they are almost immortal.

So in their camp, they just need to change their guards regularly and pass on messages back and forth. Then they waited silently for the city to be captured by their companions, and then went into the city to enjoy everything they had never enjoyed in Tubo.

That night, a soldier sleeping in the tent on the edge was suddenly awakened by a faint sound of horse hooves. As a qualified cavalry, they were still quite sensitive to the sound of horse hooves.

At the beginning, he thought it was his companion who had come back to change the duty station, but the closer the sound was, the more he felt wrong, because hundreds of people would not have such a vibration.

"Hurry up! There are cavalry approaching and the enemy attacks!"

The Tubo cavalry still had some tactical qualities, so they called their partners around them as soon as possible, and then they put on their clothes while running towards their war horses with weapons.

Cavalry, war horses are their lifeblood, and they are more important than weapons. If the weapons are gone, as long as they are on the horse's back, there is still a possibility of escaping. However, if the war horses are gone, they will basically disappear.

Their reaction was indeed a little beyond Chen Zhibao's expectations, but when Chen Zhibao led his army to arrive, only a small number of them arrived just now.

The cavalry that combines Suiyang cavalry and Yuyang cavalry has been baptized by the previous battle with the Uighur cavalry. The combat effectiveness is naturally extraordinary. At least, it has an absolute advantage in the number of people and is not comparable to this cavalry in the case of raids.

According to Chen Zhibao's request, although it was Heitian, no cavalry in this camp could run out. In order to achieve this goal, he only used 12,000 troops to attack, and the remaining 8,000 people were all used to search for fish that missed the net.
