Pang Zhong also carefully observed the speed and frequency of the rebels' attacks, which was used to determine the speed and frequency of the sergeant's fire.

When the number of rebel attacks decreases, he asks the sergeants to slow down the firing speed, so that the soldiers' physical strength can be temporarily adjusted, and the rebels attack more numerous, which only increases the firing speed. The rebel attacks began in waves, tentative in nature, and the frequency of Pang Zhong's firing was adjusted with the ups and downs of the rebel attacks.

In this regard, he is more experienced than Li Fu, and the physical strength of his sergeants is better than Li Fude's.

Pang Zhong, who was standing on the ruined city gate tower and commanding the battle, and his personal guards were not idle, and they all opened their bows and arrows and shot into the array of rebels swarming under the city.

Pang Zhong is a tiger general who has experienced a lot of wars, and he followed Gao Xianguan to fight everywhere before guarding Tongguan, and his official position is the general of the right military guard, and his position as the general of the right military guard is piled up by his own military camp.

In the past, he was very defeated, so his official fortune was prosperous.

But he rarely lost after following Geshuhan out of Tongguan to fight, but suffered a heavy defeat, the 100,000 horses he led, not organized to fight well, was defeated by the ambushed rebels with fire, in the uncontrollable defeat, he could only be under the escort of his own guards, leading a group of men and horses to break out.

This is his great shame, and he will never forget it!

In the face of the frantic attack of the rebels under the city, he wanted to use the arrows in his hand to vent the anger in his heart and save a little face.

His shot can be said to be a good shot, each arrow will definitely hit a rebel sergeant, and the rebel sergeant who is shot by him will be seriously injured if not killed.

"General, you have shot ten rebels and wounded eighteen!" One of his guards whispered the results of the battle after Pang Zhong had shot two pots of arrows.

Pang Zhong's personal results were very brilliant, but this was only what he shot hard to vent the anger in his heart.

After shooting all the arrows in the quiver, he stopped shooting and watched the progress of the battle.

In the process of careful observation, he also discovered the pattern of rebel attacks, that is, each wave of attacks was carried out in the scale of hundreds of people, and it was very scattered, coming in waves. Pang Zhong immediately understood that the rebels wanted to use this attack to consume our army's arrows, deplete the strength of the soldiers at the head of the city, and pave the way for the final large-scale siege operation.

He also made other arrangements immediately!

Pang Zhong was very experienced, and in order to know that he could not win in the end without taking some extraordinary measures against the rebels who were superior in numbers!

When it comes to strategizing, he has more experience than Lee Ford!

There are many people who are more experienced than Li Fu, and Cui Qianyou, who commanded the siege, is one of them!

"Report to the deputy marshal, the arrows of the Tang army are very dense, and our army has suffered heavy casualties!"

According to a hillside about two miles from Hantong Pass, Cui Qianyou, who commanded the front army, was riding on a horse, observing the battle in front of Hantong Pass, when a sergeant who had been hit by an arrow in the arm and was bleeding profusely came on horseback and reported the situation to him.

Cui Qianyou didn't reply, just nodded slightly, he saw the situation of the first wave of impact just now, the impact team of more than 500 people in each direction is now less than 200 people, and the two directions are about the same, and the Tang army has only shot three rounds of arrows, that is to say, the Tang army has more than 5,000 arrows in three rounds, and it has taken the lives of almost more than 500 soldiers, and the lethality of the Tang army's arrows is not ordinary.

Of course, Cui Qianyou knew that this situation was inevitable, he knew that when attacking Tongguan City, he could only fill it with the life of the sergeant, and even hoped that the life of the sergeant would be exchanged for the defenders on the head of the city to shoot all the arrows and run out of strength, so that the sergeant who was besieging the city could effectively fight back and reach the city!

When the Tang army is always exhausted, there is always a time when the arrows are exhausted, and this is the time when they have a chance to fight back.

Therefore, he could only grit his teeth and give an order, let the follow-up sergeants continue to rush forward, and wait for the opportunity to fight back!

The order was passed down quickly by the sergeant, and Cui Qianyou continued to stand on the hillside to watch the battle, and he was also cursing the ghost place of Tongguan in his heart. If the terrain of Tongguan City was not so steep, he believed that the battle situation at this time was not like this at all, and many of the sergeants under his command must have climbed the ladder to the city. But now, there are only a handful of soldiers who can rush to the city wall, even if someone is lucky enough to rush under the city wall, they are immediately shot by the Tang army on the city wall, and the ladders brought by the soldiers are also thrown in front of Tongguan City, and none of them stand on the city wall.

He had tens of thousands of soldiers under his command, but now only a few thousand of them could attack the city from several directions. The rest were unable to rush up, the terrain was too narrow. Of course, this is also his helpless emotion, if he can deploy more troops under Tongguan City, there will not be nearly 100,000 troops who have been attacking for nearly six months in a row, and still sighing at Guanguan, maybe Chang'an has already been captured, let alone Tongguan.

After a few months of attacking Tongguan without success, An Qingxu, Cui Qianyou, Tian Sizhen and other generals worked out a way to attack the city when discussing the siege strategy, that is, to attack the city continuously with hundreds or thousands of men and horses, so as to consume the physical strength of the Tang army soldiers on the city, consume the arrows on the city, and find the opportunity to enter the city.

In the continuous siege operations before the Battle of Lingbao, Cui Qianyou, who commanded the front army, adopted this method, but it did not work. Because there are too many arrows stored in Tongguan City, and they are constantly transported from the direction of Chang'an, and the number of Tang Army sergeants defending in Tongguan City is very large, and they can be continuously replenished and rotated, and the final result is that the attack for six months is fruitless.

In the end, it was through the means of showing weakness that he successfully lured Ge Shuhan out of the city to fight, and severely damaged the Tang army in Lingbao.

After the victory of Lingbao, whether it was An Qingxu or Cui Qianyou or Tian Sizhen, they all thought that the defenders of Tongguan had no fighting spirit, as long as their army went to the city, the Tang army would flee in a swarm without opening the city gate to surrender, but they did not expect to encounter the same resistance as before.

However, Cui Qianyou's thoughts in his heart have been very different from before, he knows that the number of defenders in Tongguan City is definitely insufficient, very insufficient, and it cannot withstand consumption, as long as the Tang Army's reinforcements have not arrived, they have repeatedly attacked Tongguan, and the defenders at the head of the city cannot hold Tongguan City, and he can use the corpses of the sergeants to consume the physical strength of the Tang Army soldiers at the head of the Guancheng, and the corpses of his men and horses can be used as a ladder!

Therefore, Cui Qianyou also ordered to attack continuously regardless of casualties, and adopt the tactics of crowds.

Under Cui Qianyou's orders, the rebels rushed forward one after another!
