It turned out that the second trench was much shallower than the first, and it was no wonder that they filled it so quickly. What is even more infuriating is that the north side of the trench is also a gentle slope, not straight up and down like the first trench, and they can rush through it without filling in the earth at all.

It is impossible to extend the depth of the defense to twenty li in such a short period of time if they were dug as shallower than to dig a gentle slope than to dig a cliff.

The Wuheng cavalry screamed and rushed forward directly, and there was a loud "boom" sound in the distance, countless stones fell from the sky, and the Wuheng cavalry in the gallop fell off their horses one after another, but the casualties were much smaller than the first time, and they were not completely wiped out like the last time.

Further on, the situation is almost exactly the same as before. The nails on the ground made them turn on their backs, followed by a dense rain of arrows, and then three thousand infantry armed with long knives and axes rushed out to fight them, and after finally finishing these infantry, they were faced with a wide trench.

Forced to madness by a trench on the left and a trench on the right of the Han army, he ordered the whole army to rush and kill without even thinking about it. However, this time he miscalculated again. The third trench was dug as deep as the first, and there was also a "cliff" to the north, and the more than 6,000 Wuheng cavalry who rushed to the front were once again smashed to pieces by the stone rain.

The Han art of war was originally a virtual reality, a real reality, a virtual reality, how could a barbarian like Badun understand it? Schemes are inevitable.

The Wuheng cavalry finally passed through the third trench, and there were only more than 50,000 people left in the 100,000-strong army. That is, they are not afraid of death, otherwise they may have collapsed long ago if they had changed to other armies. Even so, everyone was terrified.

Nanqiao and Khan Lu came to Badun's side together, and said: "King, the Han people are too cunning, and they can't see the enemy clearly in the dark, so it's better to withdraw for the time being, and then make a comeback after dawn, and hope that the king will think twice!" ”

Bun Dun was also hesitant, and then saw the tired faces of the soldiers around him, so he nodded and said, "Just according to your words, I will withdraw for the time being." It's okay to retreat, but tonight, these three ditches must be filled in for me! ”

In order to attack as soon as possible, these three trenches were only half filled, although they could barely ensure that the war horses could jump over, but the speed of the war horses could not be fast. Bunton asked his subordinates to continue filling in the earth, also in preparation for the attack after dawn.

The Wuheng people suspended the attack, and Shi Jian and Wang Wei were also very relieved, and immediately ordered the fourth trench to be dug. In fact, with their manpower, in such a short period of time, they also had time to dig three trenches. Otherwise, they would not have come up with a way to dig the second trench like that.

Not only was there no cover of the trenches in the future, only the hastily dug potholed fields, and even the infantry who could fight to the death with the Wuheng cavalry with long knives and axes were gone. Although a long sword and a bold axe can effectively restrain cavalry, it is not something that anyone can wield freely, and that requires a lot of strength. There were only 9,000 eligible soldiers under Shi Jian and Wang Wei, who were selected from the entire First Legion, and all of them had sacrificed their lives for the country in just half of the night. Together with the other soldiers who died in the battle, they now had only 35,000 men left, and they were mainly archers and crossbowmen, as well as a certain number of slingers. There were only 5,000 shieldmen and pikemen in the team who could fight the Wuheng cavalry for a while. If the Wuheng people rushed up at this time, it would be difficult for them to hold on.

The hesitation of the Han army gave the Han army a chance to breathe, everyone knew what the trench that was about to be dug meant to them, although there had been no rest for a day and a night, and they had just experienced a fierce battle, but no one complained, everyone sweated like rain, even Shi Jian and Wang Wei took off their clothes and armor and jumped into the trench in person.

No one thought that the three trenches they carefully set up were broken through by these fierce Wuheng cavalry in the middle of the night, and it was impossible to dig a fifth trench, this fourth trench was very important, and whether it could block the footsteps of the Wuheng cavalry depends on it.

Baskets of dirt were transported out and piled up into small mounds of different sizes at the back of the trenches, transforming the originally flat terrain into unevenness, which could have a certain impact on the actions of the Wuheng cavalry.

The east gradually turned white, the fourth trench was finally completed, Shi Jian threw away the "engineering shovel" in his hand, and fell asleep. This kind of "engineering shovel" is carefully made by the research institute according to Ma Yun's description, which is not only very convenient for excavating fortifications, but also very suitable for hand-to-hand combat, and is the standard equipment of the engineering corps. This time, these 50,000 people undertook the most important task of blocking the attack, and Xu Huang specially transferred 20,000 "engineering shovels" from the engineering corps to them, just to speed up the construction of defensive positions.

As the commander of this important battle, Shi Jian was also under tremendous psychological pressure, and he had to seize the time to rest in order to recover his energy and physical strength as soon as possible. Many of the young soldiers also lay down, they were so tired that if they didn't sleep for a while, they would not even be able to draw their bows.

Wang Wei temporarily took over the command, he grabbed the clairvoyant mirror and watched nervously the movements of the Wuheng cavalry on the opposite side. The sky was getting brighter, and the unkempt yellow hair of those Wuheng cavalrymen could already be clearly seen. Wang Wei lifted the clairvoyant mirror slightly, looked farther away, and suddenly found that a large cloud of dust had risen over there.

Seeing this scene, Wang Wei was slightly excited, estimating that it should be the arrival of the Han army's ambush, he gently poked Shi Lian, who was snoring, and suddenly the expression on his face froze, and a trace of cold sweat oozed from his forehead.

In the clairvoyant mirror, a red flag fluttered in the wind, and a big "Yan" character on the flag told Wang Wei that this was not an ambush of the Han army, but a cavalry of the Yuan army, and Yan Liang personally led the troops.

Shi Jian didn't sleep dead, he was stabbed by Wang Wei, and immediately jumped up from the ground and asked loudly, "General Wang, what's the situation?" ”

Wang Wei handed over the clairplane in his hand, and said worriedly: "General Shi, please look, Yan Liang's army has arrived." ”

Yan Liang and Wen Chou are also known as the two famous generals in Hebei, and their prestige has already spread to Jingzhou, and Shi Jian and Wang Wei have heard of it. Hearing that Yan Liang had arrived in person, Shi Lian couldn't help but feel spirited. The so-called fame is better than meeting, Shi Jian followed Xu Huang and others very early, Liu Xin's six righteous brothers, which one did not have the courage of Wanfu, he didn't believe that Yan Liang could be so powerful, if he could kill Yan Liang in one battle, he would be famous all over the world.

Taking over the clairvoyant mirror in Wang Wei's hand, Shi Jian really saw a commotion in the Wuheng cavalry, and a few horses rushed south, the cloud of smoke and dust in the south came very quickly, and there was no doubt that he was a cavalry. Although Shi Jian was ambitious, he didn't dare to forget his mission, and with a wave of his hand, his own soldiers released a signal, and ten yellow fireworks exploded in midair.

It was Yan Liang and the 100,000 Yuan cavalry under his command who came, which was a force that the Yuan army was proud of, and in the battle with Cao Cao, it was the cavalry led by Yan Liang and Wen Chou who repeatedly turned the tide.

After Badun led the Wuheng cavalry to leave Liyang, it took another two hours for Yan Liang's cavalry to assemble. The cavalry of the Yuan army were not as able to endure hardships as the Wuheng cavalry, and marching overnight was too demanding for them. However, worried about the safety of Yecheng, Yan Liang still kept urging the team, and it was not until midnight that he found an open area to camp and rest, and called the soldiers again before dawn, so that he successfully joined forces with the Wuheng cavalry before sunrise.

Hearing that the Wuheng cavalry fought all night and lost half of the men and horses, Yan Liang was also surprised. However, Yan Liang has always had the best face, and he was even more reluctant to show the slightest hesitation in front of the three of Badun, Nanqiao, and Khanlu, so he couldn't help sneering, waved his hand, and said: "King Badun, you have fought all night and worked hard. Please watch the enemy for Yan on the side, and see how Yan breaks the enemy! ”

He originally wanted to explain the tactics of the Han army to Yan Liang, telling Yan Liang that the Han army had a "demon method" that could make war horses and horses stumble, a bow and crossbow with a range of up to 400 paces, and a giant axe that could split cavalry companies and horses in half. But seeing Yan Liang's arrogant face, the words that came to his mouth shrank back.

You must know that even if Yuan Shao is humble and polite when he sees Badun, you Yan Liang is just a brave man under Yuan Shao, why do you put on a prestige in front of my Badun. What's more, in the battle last night, Wu Heng suffered heavy losses, and he didn't feel any problems when he fought fiercely, and as soon as he stopped to rest, his morale was obviously much lower. Not only Badun, but even Nanqiao, Hanlu and other Wuheng cavalrymen, after listening to Yan Liang's words, their hearts were all unhappy.

Yan Liang didn't pay attention to the expressions of Bang Dun and the others at all, waved his horsewhip lightly, and swept past them with his own men and horses, choking the faces of Bang Dun and the others with dust.

However, they had already made themselves look like mud monkeys when they had taken off their clothes three times last night to hold the soil, and they didn't care about a little more dust.

Yan Liang took the lead, came to the front of the two armies, put his hands on the pergola and looked into the distance, the battle last night left the remains of many soldiers on both sides, and now they have been buried by the order of the two armies, and there are not many traces to be seen. The Han army on the opposite side was hidden under the trench, quietly, and there was no one in sight. Yan Liang couldn't help but smile contemptuously, pointed at the big knife in his hand to the opposite side, and shouted in a deep voice: "Kill!" ”

The cavalry attack of the Yuan army was not like Wu Heng rushing forward, but was divided into attack waves of varying numbers according to the number of troops. Yan Liang led a full 100,000 cavalry today, and with more troops, there were more options to choose from. The first wave of attack he sent out was five thousand light horsemen, which was also a tentative attack.
