Overnight, the Liang army set up three large camps to the west, north and south of Yuzhang City, forming a three-sided encirclement.

In the morning, the Liang army cut wood to build siege equipment, preparing to start the siege in the afternoon.

Zhang Shan'an was worried that the south was close to the hinterland of the Sui army and was vulnerable to the Sui army's attack, so he only left 1,000 troops outside the southern city, while he led 2,000 troops to garrison the large camp in the north.

Zhang Shan'an's feint army is just for show, and relying on his army to capture a wall of Yuzhang City is simply wishful thinking!

Therefore, when the 1,000 troops in the south and the 2,000 troops outside the northern city approached the range of the Sui army's bow and arrow fire in Yuzhang City, they stopped. Zhang Shan'an's army retreated after a nois, and then organized another attack.

This repetition just gave the Sui army in Yuzhang City an impression that I was besieging the city.

At the beginning, Gong Chen, the general of the defenders on the north wall of Yuzhang City, and Dong Ren, the general of the defenders on the south city wall, did not understand whether the enemy was testing or what conspiracy was behind them?

But Zhang Shan'an repeated it so repeatedly that the Sui army on the city wall suddenly realized in his heart, Nima, this is a disguise!

In this way, the guards of the northern and southern walls were much easier.

Looking at the western city wall, it is different, Suhuer is very cunning, and the first formation sent 3,000 troops to participate in the attack.

The 3,000 troops braved the rain of arrows to force the attack, and after hundreds of casualties finally reached the city wall, set up a ladder and began to attack the city. The Sui army on the city wall did not show weakness, and the rolling wood and stones smashed down, causing heavy casualties to the soldiers of the Liang army besieging the city.

Just when the Sui army was busy dealing with the siege Liang army, Su Huer's second echelon suddenly appeared, taking advantage of the Sui army's unpreparedness, quickly approaching the city wall to reinforce the first echelon.

At this time, the Liang army that participated in the siege of the city became a little thick, and the siege battle became more and more intense.

The problem is that this is not the end, the second echelon of Suhuer has just joined the siege ranks, and the third echelon has set off immediately after it, quickly advancing forward.

Xin Wen, who was guarding the western city, did not expect this to happen, and they were concentrating on dealing with the besieging Liang army, causing the second and third waves of Liang troops to pass through the bow and arrow firing area and enter the city wall.

Nearly 10,000 Liang troops participated in the siege, so that the 2,000 Sui troops guarding the west city were in a hurry, and soon a dangerous situation appeared.

However, the general who defended the city, Xin Wen, soon gained insight into Suhu'er's conspiracy.

Xin Wen fought with Lu Chang, not to mention anything else, he learned a lot of intrigues and tricks, and Su Hu'er couldn't hide this trick from him.

Xicheng is the main direction of attack of the Liang army, and the other city walls are all feints!

Xin Wen immediately made a decision to transfer 2,000 reserve troops to the city wall to strengthen the garrison and replace the tired Sui soldiers at any time, so the 4,000 accompanying army and the more than 9,000 Liang troops started a big battle on the west city wall.

At the same time, the garrison of Yuzhang City was not idle, they organized the people in the city to carry war materials and provide logistical support for the soldiers defending the city.

The offensive and defensive battle of Xicheng entered a white heat, and the 9,000 troops of the Liang army set up cloud ladders to storm the city fiercely, taking advantage of the advantage of a large number of people to brave the rain of arrows to attack. The Sui army did not show weakness, and the bows and arrows continued to shoot the Liang soldiers who were besieging the city, and smashed the Liang army who were climbing the city wall with rolling wood and thunder stones, causing heavy casualties to the Liang army. The entire western city wall was full of killings, and the battle was fierce.

What's more, hot oil was poured down, and even a wooden ladder was lit with fire.

The Liang army continued to fall off the city wall, and at the same time, new ladders were erected to allow the Liang army to join the siege.

Of course, many Liang troops climbed over the city wall and engaged in hand-to-hand combat with the Sui soldiers defending the city.

However, there were too few Liang troops who could attack the city wall, and they were quickly killed by the Sui army in the city.

The Sui army general Xin Wen Xin Jingbo held a pair of bright silver hammers, where the danger appeared, the dancing bright silver hammer touched the weapon, the weapon flew, and the head was smashed when it hit the head, and it was fierce and abnormal.

"Kill! Kill, kill, kill! ”

"Kill! Kill, kill, kill! ”

Xin Wen shouted while fighting, and the Sui soldiers behind him also shouted, and suddenly the sound of killing on the city wall resounded throughout Yuzhang City.

The attack and defense of Yuzhang City lasted for nearly an hour, although the Liang army attacked fiercely and once stood on the city wall, but in the end it was in vain.

The fighting was quite fierce at this hour, and the 9,000 troops of the Liang army almost lost nearly 1,000 soldiers, which shows that the battle was fierce.

Although the Sui army had the advantage of occupying the city wall, the casualties were not small, and almost hundreds of people lost their combat effectiveness.

The soldiers of the Liang army were tired, and Su Hu'er, who was watching the battle in the rear, knew that he could not take Yuzhang City for a while, and this group of troops needed to withdraw and rest.

Su Hu'er didn't expect to take Yuzhang City in the first siege, this was just the beginning. Moreover, Su Hu'er is planning to use this attack to once again test how many troops there are in Yuzhang City, and now, it should be said that he knows it in his heart.

Now that we have figured out the details of the Sui army, we can report the situation in Yuzhang City to Xiao Mo today. Since Yuzhang City has this little bit of soldiers and horses, Su Huer is confident that he will take this city.

Looking at the time, Suhuer felt like she could attack again.

In this attack, Suhuer still attacked in three echelons, but the details changed a little.

The first echelon was still 3,000 people, braving the rain of arrows, the first echelon attacked under the city wall, erected a cloud ladder and climbed the city to attack.

Immediately after that, the second echelon began to dispatch, but this echelon was 4,000 people, and Su Huer secretly increased his troops with calculations.

When the second echelon arrived at the foot of Yuzhang City, the third echelon set off. Moreover, the third echelon dispatched five thousand people at once.

Nima, although still three echelons, has increased its strength to 12,000 people.

This time, there was a huge disparity in the strength between the attack and defense, and the Sui army in Xicheng in Yuzhang City was only 2,000 people, and even if the reserve army was added, it was less than 4,000 people, and the strength ratio was three to one.

Another point is that because Su Hu'er is secretly increasing his troops, it is easy for Xin Wen, who is guarding Yuzhang City, to mistakenly think that it is still an army of 9,000 people.

I have to say that Suhuer is still very cunning.

12,000 people attacked a city wall, and the troops were still very concentrated, which made the pressure on the defending Sui army suddenly tense.

The soldiers of the Sui army were constantly injured and could not participate in the battle, and the reserve army was constantly replaced. Moreover, these reserve forces also have to take on the task of replacing soldiers who are too tired, and they have to take turns to fight, otherwise they will not be able to sustain such a high-intensity battle.

Xin Wen was sweating a little, Nima, Suhu'er is dying, paralyzed, this is to take the city on the first day?

Although the Liang army attacked the city fiercely, it was not so simple to take Xicheng. Although the Sui army has a small number of troops, it can occupy the city wall, even if some soldiers climb the city wall, it is indeed very difficult to occupy the city wall.

Of course, if the Sui army is tired after a long battle, it may really be able to break through a city wall and pose a huge threat to the Sui army.

Just when the attack and defense of the West City were at its most intense, Zhang Qiang, the general guarding the East City, sent a thousand troops to support.
