The 200,000 rebel army led by Shang Rang quickly rushed under the city wall, and the formation spread out to the side, forming a semicircle, and surrounded the 20,000 Tang troops with their backs to the city gate.

On the tower of the city, the drums fell like raindrops, directing the Tang army under the city to attack. Two thousand crossbowmen fired in batches, and the rain of arrows continued incessantly, and the arrows beckoned to the rebel cavalry who rushed at the front.

Rebel cavalry were constantly hit by arrows and fell from their horses, and corpses continued to pile up on the ground, forming hills with the effect of hindering.

As a result, the offensive of the rebel army slowed down slightly, but under the command of Shang Rang, it quickly resumed its original pace, divided into two groups, and attacked the flank of the 20,000 Tang army.

On the city wall, Liu Yu smiled slightly when he saw this and handed down the military order. The rhythm of the drumsticks in the hands of the wrestlers changed sharply, and the two thousand crossbowmen of the Tang army left while fighting, and soon retreated into the shield array.

The rebel cavalry who had been flanked by them were immediately shut up, and they were dismounted by the spears that stretched out from the shield array.

"Here's the opportunity!" Liu Yu smiled slightly and pointed to the middle finger of the rebel army.

Yan Lie and the generals looked in the direction of his finger, only to see that the cavalry of the rebel army was in a hurry to attack, and threw off the infantry of their own formation hundreds of paces.

This is a very common phenomenon in war, but somehow it became an opportunity here in Liu Yu?

Liu Yu shook his hand, and the sound of war drums changed again.

The shield formation formed by the 20,000 defenders suddenly opened, and the 3,000 Tang cavalry hidden in the formation rushed out and went straight to the main position of the righteous army.

The foot soldiers in the rebel army's main formation were chasing their own cavalry, where did they have time to form a formation, and they were killed and scattered for a while.

Seeing this, the cavalry of the rebels, who had already rushed to the front of the Tang army, hurriedly returned to the rescue. But those Tang cavalry were as cunning as rabbits, and when they saw the enemy chasing after them, they quickly retreated back into their own shield array.

Those rebel cavalry were greatly annoyed by the Tang army's sneak attack, and chased after them, and were once again stabbed down by the spears stretched out from the Tang army's shield array.

Seeing that the situation was not good, the cavalry of the rebels retreated one after another. But the crossbowmen of the Tang army, who were hiding in the shield array, were unforgiving, and they launched arrows in pursuit, killing and wounding thousands of rebels.

Yan Lie and the generals did not expect that under the dispatch of Liu Yu, the 20,000 defenders could still fight the 200,000 righteous army without any temper, and they were greatly admired for a while.

But Shang Rang, the chief general of the righteous army, was not a mediocre person after all, he quickly stopped the chaotic situation of the righteous army, and reorganized the offensive formation, the speed was so fast that Yan Lie and the others were dumbfounded.

However, all the generals who have been fighting all the year round understand a truth, it is quite easy to pursue while the victory is won, but it is very difficult to be in danger.

This is still able to do this easily, and live up to the name of a famous general.

Even Liu Yu himself could see that although the 20,000 Tang troops under his command had killed and injured thousands of righteous soldiers, they had not shaken their fundamentals, and they could only be regarded as a drop in the bucket.

Shang Rang led the rebels to continue the attack, and the Tang army repeated the old tricks under the command of Liu Yu, constantly sending cavalry to harass the rebels' main formation, and then retreated into the shield array when the situation was unfavorable, relying on the spear defense formation to resist the pursuit of the rebel cavalry.

The 2,000 crossbowmen hiding in the shield array continued to shoot cold arrows, killing and wounding many rebel soldiers.

But Shang Rang was not an easy person, he quickly understood the characteristics of this formation of the Tang Army, constantly changed his own formation, launched an extremely tight defense in this formation, slowly advanced, and marched step by step.

Even if the cavalry of the Tang Army attacked again, it would be difficult to get any gains.

More than 190,000 horses slowly approached under the city wall, although the speed was not fast, but every inch of land advanced extremely solidly, which made Yan Lie and the others standing on the city wall feel a sudden pressure in their hearts.

On the battlefield, a storm is coming.

Liu Yu was not alarmed or impatient, he passed down one military order after another, and the 20,000 Tang troops under the city began to change rapidly under the mobilization of drums. The three thousand cavalry of the Tang Army actually put away their sabers, took off their cuirasses, replaced them with bows and crossbows, turned into rangers, and once again rushed out of the shield array.

Seeing this, the foot soldiers in the rebel army's main formation raised their spears one after another, preparing to stab at the attacking Tang cavalry. But they never expected that this time it was an arrow that attacked them. Caught off guard, one after another, people were hit by arrows and fell to the ground.

The 3,000 cavalry of the Tang Army relied on the advantage of speed and kept shooting around the main formation of the rebels, as if they were shooting a slow-moving live target.

As a result, the rebel army was in chaos, and people began to trample and collide with each other in a panic, and thousands of people died as a result.

Seeing this, the cavalry of the rebel army who had originally left their own formation to attack the shield formation of the Tang army had to turn their horses and return to defense, but the cavalry of the Tang army did not wait for them to approach, and then retreated into the shield formation again, as cunning as a crucian carp in water.

Countless spears flashed out from the Tang Army's shield array, once again beckoning to these poor rebel cavalry.

After going back and forth several times, Shang Rang's righteous army lost more than 10,000 horses, but he was never able to help this Tang army, which only had 20,000 people.

The rebels immediately retracted their formation and sent a large number of archers to the front of the formation, ready to meet the cunning and hateful Tang cavalry. But this time, the cavalry of the Tang Army did not move, but hid in the formation, waiting for the shield formation to attack from both flanks.

The five thousand Tang saber and shield men pulled up their shields on the ground, rushed towards the enemy formation, and soon engaged the rebel archers in one place. Each of them held shields to block the arrows fired from the rebels, and rushed forward and brandished long knives, and the rebel archers, who had no time to take the arrows again, cut them to the ground.

The situation on the battlefield was fierce, and although the Tang army was small in number, it was always in the position of taking the initiative to attack under the dispatch of Liu Yu.

This battle lasted until the evening, although the Tang army killed tens of thousands of heads, but it was never able to completely break through the formation of the rebels, and even was almost surrounded by the rebels several times, relying on the strength of the rebels, and almost became a turtle in the urn. Fortunately, thanks to Liu Yu's proper command, the Tang army was able to stabilize its position and resist the continuous and tidal impact of the rebel army.

As the sun sets, night falls.

Liu Yu ordered the Tang army to retreat into the city, but Shang Rang did not dare to pursue, and took the remaining rebel army to retreat in the direction of the main camp.

Yan Lie took the generals to the city to count the casualties of the Tang army, and found that there were more than 300 dead and more than 500 wounded.

Seeing this, Liu Yu couldn't help frowning, sighed deeply, and said to Yan Lie and the others: "This Shang Rang is really powerful, he only used ten times my troops, he can block my attack, and live up to his reputation as a famous general!"

Yan Lie and the generals hurriedly persuaded: "My lord is too himself, if we get such a result, I'm afraid it's too late to show off to others." ”

Liu Yu shook his head again and again, his face was solemn, "Although you have been defending the city for a long time, you don't know the pattern of today's war, if 20,000 can't defeat the 200,000 soldiers and horses led by Shang Rang, then the 90,000 Tang army will be difficult to repel the Huangchao million army, and at present, there is a shortage of materials and money and food, I am afraid that Chang'an City will not survive this winter." ”

At night, he stood on the city wall and looked into the distance, and he could vaguely see that there were countless rebel barracks on the banks of the moat. These barracks are scattered, and they are horns of each other, and they secretly cooperate with the principles of attack and defense. It can be inferred from this that most of the generals in the army should be well versed in the art of war.

Liu Yu sighed deeply, feeling that the upcoming battle would be very difficult.
