The next day, the Tang army began to attack Qingtang City.

Compared with the weak siege battle of Tubo, the Tang army's siege seemed grand.

In the open space under Qingtang City, 20,000 cavalry stood in a row, and in front of them were divided into ten siege formations of five thousand people. In each siege formation, there were one hundred catapults, one hundred ladders, and one hundred crossbows. Among the five thousand people, only these three hundred siege equipment used two infantry, and the remaining three thousand infantry were the real siege vanguards.

Du Junchuo stood in the position of the central army and began to slowly command and mobilize. He was surrounded by General Su Dingfang and Deputy General Cheng Mingzhen.

Because, when the task of siege was handed over to Du Junchuo, Su Dingfang chose to remain silent and acted as a spectator. When Du Junchuo held the flag, the big drum of "dong dong dong..." sounded, and the sound of the drum shook the sky.

The Tang army began its first siege.

In the first group of siege, Du Junchuo sent a square formation of 5,000 people to order the big ones. Five thousand Tang soldiers began to push the ladder and the crossbow slowly to Qingtang City, and the catapult cart behind them began to throw the big stones to Qingtang City. When the siege infantry reached an eight hundred steps away from the corner of the city wall, the crossbow soldiers stopped. They began to choose effective locations and aimed the crossbow at the tower of Qingtang City.

Because Tubo has been in Qingtang City for many years, the city is tall and sturdy, easy to defend but difficult to attack.

However, the ladders and catapults were made by Lu Dongzan, who captured Han craftsmen under the city of Liangzhou. When Lu Dongzan's army retreated, these engineering equipment had been burned up by Li Ke. Therefore, even in the tall Qingtang City, there were neither catapults nor crossbows on the city tower, and there were only tens of thousands of Tubo defenders.

Therefore, in the face of such defense, the Tang army's catapult cart and crossbowmen simply regarded Qingtang City as a training ground and Tubo soldiers as targets for their activities.

Every big stone fell onto the city wall and killed many Tubo soldiers guarding the city.

The bed crossbows are even more fierce. They have very high accuracy. They often shoot two and three Tubo defenders with one long arrow. The Tang army's bed crossbows were powerful and saw a two-meter-long arrow breaking out of the air and roaring at a Tubo centurion on the city tower. Before the Tubo centurion came to his senses, he found that he was pushed by a force, and then his chest hurt and found that he had been nailed to the pillar behind him.

He kept screaming and calling, but none of his companions were willing to help him.

Because the Tang army's long arrows and stone casting cars were powerful, and the Tubo defenders on the city wall were in chaos. They just wanted to avoid the long arrows and big stones, so they had time to rescue their companions.

When the centurion, who was nailed to the pillar, was screaming with weakness, he could see a stone as big as a mill fan hitting his head.

Zhuo Qing, who was watching the battle from a distance, had no expression on his face, and he wanted to look at the Tang army infantry under Qingtang City, storming towards Qingtang City like a stone statue.

Two hundred steps!

...

Eighty steps!

Fifty steps!

When it was fifty steps away, the Tubo defenders recovered from the chaos just now and began to resist effectively.

Their archers showed their might and shot feather arrows at the Tang army infantry.

The Tang army infantry was shot over by a rain of arrows, and the pace of siege was curbed.

However, just as the rain of arrows from the Tubo defenders ended, they heard a scream from the city tower, "Ah--" A Tubo archer fell off the city wall.

Because the Tang army's crossbow soldiers began to show their power, they turned their eyes to the archers on Qingtang City.

A two-meter-long arrow broke through the air with a "swoosh" sound, shooting towards Qingtang City, nailing the Tubo archers to the wooden pillars of the city tower behind him.

With the power of the crossbow, the Tubo archers were suppressed, and the Tang army's infantry began to advance to the city, and the cloud ladders were constantly moving towards Qingtang City.

In just a few breaths, the Tang army had already reached the city of Qingtang.

The Tubo people's archers could not get the advantage, so they began to throw the big stones down the city and smashed them at the Tang army's infantry siege.

"Ah——" Screams continued, including Tubo soldiers who were nailed to death by long arrows, and Tang army infantry who were killed by big stones.

The scene is very tragic!

However, after all, there were very few crossbow soldiers in the Tang army and there was no way to completely suppress the archers in Tubo.

Therefore, the Tang army's siege infantry also threw down hundreds of corpses halfway through the way when they captured Qingtang City.

At this time, the ladder slowly moved to the bottom of Qingtang City.

The Tang army began a large-scale battle to climb the city!

"Kill--" Zhuo Qing yelled, "Kill them down the city wall!"

"Arrowman, hurry up, aim at the ladder!" Zhuo Qing said angrily.

Under his command, the Tubo defenders began to slowly counterattack the Tang army, and soon used their advantage of admitting defeat to suppress the Tang army's crazy arrogance.

However, it curbed the arrogance of the Tang army infantry.

Without the construction tools such as crossbows and catapults, the Tubo people could not stop the Tang army's ladders. Then hundreds of ladders slowly leaned towards Qingtang City. The highest wooden box on the ladder opened, and dozens of Tang army infantry rushed out from inside, and they rushed towards Qingtang City.

"Kill--" Tang army infantry rushed out of the wooden box and rushed towards the Tubo defenders on Qingtang City, creating opportunities for their companions under the city wall around them.

Although there were not many Tang army infantry in the cloud ladder, there were enough people rushing out of the 100 cloud ladders, reaching more than a thousand. This force rushed towards Qingtang City, occupying a southeastern position in Qingtang City, creating an opportunity for the companions under the city to climb the city.

"Quickly - go and stop them!" Zhuo Qing saw that Tang Jun controlled the southeast of Qingtang City, and shouted to the guards beside him.

"No——" The personal guards around Zhuo Qing received the order and saw more than 3,000 Tubo soldiers guarding the city storming towards the southeast of Qingtang City.

"Kill--" Both sides met, and they were all enemies, and their eyes were red.

So, as soon as you come into contact, the swords intersect, blood flows and flesh and blood flows.

However, these three thousand Tubo defenders did not stop the large number of Tang troops from rushing to the city. Because their companions on the city created opportunities, the siege infantry under the city continued to kill towards the city.

"Follow me!" Zhuo Qing roared, and he personally led his two thousand personal guards to the southeast of Qingtang City.

Zhuo Qing joined the battle group and effectively curbed the attack of the Tang army. In addition, due to Zhuo Qing, the Tubo defenders were fiercely convinced. The Tubo defenders were blocked in front of the Tang army like a wall. When one Tubo defender fell, another Tubo defender was on the top of the position of his companion.

Such continuous fighting has consumed many Tang army infantry on the wall. Tang army infantry is constantly decreasing, while Tubo defenders are constantly increasing. Gradually, the Tang army loses its advantage on the southeastern city.

"You can withdraw your troops!" Du Junchuo said to himself.

Immediately, he issued an order to retreat.

Singing the gold and withdraw the troops!

Hearing the signal of withdrawal from his formation, the Tang army siege retreated like a tide.

In fact, Du Junchuo's siege this time was just a test, and he wanted to find out the city defense power and deployment of the Tubo people.

Now, after experiencing such a siege battle, he has already understood the advantages and disadvantages of the Tubo defenders, so naturally there is no need to continue siegeing the city and consume the lives of his soldiers.

The Tang army withdrew, and the Tubo defenders on the top of Qingtang City breathed a sigh of relief.

However, Zhuo Qing, the guardian of Qingtang City, looked even more ugly.

Because he knew very well that today's siege was just a tentative attack by the Tang army.

However, with just such a tentative attack, the Qingtang City he guarded was almost broken. If the Tang army attacked the city on a large scale, how should he defend the city? He himself knew very well that the Tubo people were not good at defending the city and were suitable for night battles. However, he had to face more than 100,000 elite cavalry, or 30,000 heavy cavalry soldiers, what would be the way to fight such night battles and death?

Therefore, Zhuo Qing hoped that reinforcements would arrive early at this time.

Because, with such a desperate defense, he knew very well that sooner or later the Tang army would be captured by Qingtang City.

He heard about the Southern Front Battle and said that the Tang army attacked the cities and slaughtered the cities and slaughtered prisoners along the way. So he didn't dare to think about what would happen if the Tang army really captured Qingtang City, and the 100,000 defenders and 500,000 Tubo civilians in Qingtang City? Will it really be killed by the Tang army?

The afterglow of the sunset shone on the city tower of Qingtang City, warm and comfortable. But Zhuo Qing couldn't feel it at all. Instead, a wing of two hit his heart, making him unable to walk away for a long time.
