[The second shift is delivered, and there is a third shift before twelve o'clock]

It was the first time that the defenders in the checkpoint had been baptized by rockets and explosives, and they had been beaten by the First Cavalry Division, and the defenders had been mixed together, and in the face of the charge of the First Cavalry Division, the defenders of the checkpoint could not control the situation even if they killed several people, and organized the defenders to resist the First Cavalry Division.

The 1st Cavalry Division was getting closer and closer to the checkpoint, and the 500 black cavalry armed with beaded guns kept firing at the checkpoint as they charged, making the checkpoint even more chaotic.

When the 1st Cavalry Division approached the checkpoint, the black cavalry drew their revolting guns one after another, and at this time, the defenders in the checkpoint had already entered the range of the black cavalry, and the sound of bursting beans sounded.

Bang! Bang! Bang! Bang! Bang! Bang!

The black cavalry emptied the six bullets in the revolver, quickly took out another reincarnator, and fired six more shots in a row.

Waves of bullets rained down towards the guards, who were mixed up in the checkpoint, and under the rain of bullets, the Tang soldiers were swept down in a pool of blood like cutting wheat.

Nearly half of the soldiers died on the spot, and many soldiers were injured by bullets, wailing incessantly, and the number of uninjured soldiers in the checkpoint is estimated to have dropped to less than 8,000.

Run!

Seeing that there was nothing to do, Tian Shang, the guard of the checkpoint, was the first to take the lead in escaping, then the guard's personal guards, and finally the other soldiers who could still move, they fled to the back of the pass, leaving the checkpoint full of wounded soldiers.

The 1st Cavalry Division, which had just rushed into the checkpoint with a cavalry sword, was littered with wounded soldiers and dead corpses.

In the next half an hour, the First Cavalry Division used all the explosives bags it carried with it in the three or four miles near the exit of the Zhengguan Road, and if the Tang Army wanted to dredge it in the future, it would at least take at least three months to mobilize a large amount of manpower.

After doing this, the First Cavalry Division quickly left the checkpoint, Yun Hao did not forget that there were still a large number of pursuers rushing towards the checkpoint, and if he didn't leave, the First Cavalry Division would be surrounded by these pursuers.

In the checkpoint, those wounded soldiers were still lying on the ground, Yun Hao did not choose to kill these wounded soldiers, leaving these wounded soldiers, but instead became a burden for the Tang army that entered the pass.

The task of destroying the passage has been completed, Yun Hao breathed a sigh of relief in his heart, in the next nearly half a month, Yun Hao led the First Cavalry Division to make trouble everywhere in the control area of Feng Ye's army, and also brought huge losses to Feng Ye's army.

On the third day after Zhengguan Road was destroyed by the exit, Feng Ye finally received the news, and after seeing the news, Feng Ye's heart suddenly felt cold.

"How is that possible? How can it be? Feng Ye kept muttering, obviously this news made Feng Ye difficult to accept.

Feng Ye had received a force of enemy cavalry into the area controlled by the Tang Dynasty army before, and then Feng Ye mobilized an army to encircle and suppress this cavalry.

Feng Ye felt in his heart that this cavalry was probably going to conquer the pass, but there were 20,000 defenders on the pass, and this cavalry alone should not be able to break through the checkpoint, and the cavalry would not be able to attack the city.

However, the black cavalry is different from all the cavalry in Feng Ye's impression, even if it is not this kind of wooden level but a city with tall walls, the black cavalry can attack, but the losses will be greater.

After a long time, Feng Ye regained his composure and fell into thought.

The Zhengguan Road was temporarily blocked, and it would take at least a few months to reopen the Zhengguan Road, and in these few months, Feng Ye's army had to fight alone.

Feng Ye has deeply realized that the Yun army, which has been holding on to the Tang army led by him for more than two months, is very strong, and is equipped with that kind of strange weapon with a long range and great power, most of the time, the Tang army is in a state of beating, constantly losing troops and losing generals, and the number of casualties of the Yun army is very small.

Whenever Feng Ye divided his troops and prepared to encircle the Yun army, the Yun army would quickly retreat and fight with the Tang army, and the Tang army could only converge again, if it did not converge, the number of its own casualties would only increase.

Feng Ye will no longer be able to get reinforcements in a short period of time, which means that Feng Ye's army will continue to be at a disadvantage in the confrontation with the Yun army, so how long will Feng Ye's army last.

In the end, Feng Ye decided to transfer all the Tang troops under the control of the Tang army in eastern Hengzhou back to Duqu County.

Duqu County is also the county where Zhending County is located, Feng Ye plans to withdraw all his troops, stick to Duqu County, and wait for the road to conquer the pass, and at the same time, Feng Ye wants to shrink himself as much as possible, so that the two major forces in the Guannei Yun Clan and the Wang Clan fight, so that the Tang Empire is more likely to conquer the Guannai.

With Feng Ye's order, the Tang troops stationed in various places in the eastern part of Hengzhou retreated to Duqu County, and Lin Zhe also sent cavalry troops to harass the Tang army.

In the middle of June, all the Tang troops had withdrawn to Duqu County, Feng Ye counted all the horses under his command, and there were only a little more than 180,000 left, and the most disappointing thing for Feng Ye was that the two elite troops that Feng Ye brought into the pass were the Xuanjia Army and the Flying Leopard Cavalry, the Xuanjia Army was almost wiped out, and the Flying Leopard Cavalry also suffered heavy losses.

The Tang army withdrew to Duqu County, and Lin Zhe's army also came outside Duqu County.

Lin Zhe summoned Yun Jing, Yun Hao, and Chang Jichun to discuss the next battle deployment, Lin Zhe personally led the Second Infantry Division and the Fourth Infantry Division to attack Duqu County from the front, Yun Hao led the First Cavalry Division to the south of Duqu County, Chang Jichun led the Second Cavalry Division to the north of Duqu County, the main task of the two cavalry divisions was not to attack the Tang army in Duqu County, but to prevent the Tang army from escaping from the south or north, so that Lin Zhe's army would have to work a lot to destroy the Tang army.

The tactics of Lin Zhe's army are the same, but this time the Tang army stationed in various cities did not escape, even if the city wall of the city was shattered by Lin Zhe's army, the defenders did not retreat, and continued to hold on, Feng Ye had to persist as much as possible until the Zhengguan Road was opened, and now the Tang army led by Feng Ye has not much way to retreat, unless it enters the other areas of the Jiuling Mountain Range, which are full of dangers and have not been explored.

For the elimination of the Tang army in Duqu County, Lin Zhe's army adopted the tactics of steady and steady fighting, and did not blindly capture the city, which would cause Lin Zhe's army to suffer heavy losses.

Just shelling, explosives bag bombing, at most three days, can take a city, the city wall has been completely destroyed, under the continuous bombardment, the morale of the Tang army has plummeted, has long lost the original want to conquer the high momentum of the pass.

Death is not terrible for the soldiers, some people already have the consciousness of death when they become soldiers, but such an aggrieved death makes it difficult for many Tang soldiers to accept.

When Lin Zhe's army attacked the city, there would even be a Tang army coming out of the city and launching a suicidal charge against Lin Zhe's army.
