Shan Xiongxin nodded and took five trebuchets and pushed five carts forward.

Sui is approaching the distance, the trebuchet of the Goguryeo people is powerful, the stone bullet the size of a human head falls from the sky, Yuwen Chengdu can no longer care about the feather arrows above his head, and with a shout, the shield soldiers in the front row will erect the tower shield, and after the three crane beak hoes are deeply rooted in the ground, they quickly retreat a step back, so as not to hit the giant shield and then shock the shield soldiers, Shan Xiongxin took two hundred people to line up in a horizontal row, closely following the back of the guards of the five thousand emperors.

The boulder smashed on the giant shield with a bang, and the giant shield suddenly sank down a large piece, some boulders crossed the giant shield and fell into the scattered guards of the Son of Heaven's army, smashed on the dry and hard ground and then shattered, the flying stones clanged on the thick armor of the foot soldiers, as for the guards of the Son of Heaven who were directly hit by the boulder, there was only a pool of blood on the ground, and as for the corpse, the boulders with strong passive energy were smashed alive and fell all over the ground.

Fortunately, the guards of the Son of Heaven's army are the most elite soldiers selected from the twelve guards, and each soldier can be called the king of soldiers in the original army, and the first wave of the guards of the Son of Heaven's army are wearing heavy armor, and they are used to fighting the king of soldiers, although they are frightened, no one retreats a step back.

The Sui army who followed behind did not have the slightest timidity, he roared angrily, and the shield soldiers tried their best to pierce the deformed tower shield into the ground, and the spears of the pikemen soon poked out of the muzzle of the tower shield, and the entire army formation was like a huge hedgehog.

The Eight Bull Crossbow also changed its strategy, no longer firing strong crossbows at the city wall, and shooting at the city gate under the order of Yuwen Chengdu.

Huge crossbows. The gun roared past the two hundred operators led by Shan Xiongxin, like a crazy hornet swarm, making their scalps tingle.

Then they saw the most terrifying scene in the world, countless Goguryeo cavalry were flying in the air, their bodies being crossbowed. The spear pierced through the belt, and then shook wildly and was nailed to the city wall.

No matter how many people are crossbowed. The guns were taken away, and the huge city gate was like an exit from hell, and there was still a steady stream of cavalry being spit out of the exit, and soon joined the war.

Obviously, Yuan Taizuo may have realized that the secret weapon that Wang Junlin used in Annan County has appeared here.

"Can you project a powder pack at this distance?" Shan Xiongxin asked in a low voice the 100-person commander who was responsible for directing and measuring the projectile explosives package around him.

The hundred-man chief said calmly: "It's better to be closer, in that case, it's safer." ”

The Goguryeo cavalry roared and interspersed left and right on the battlefield, it could be seen that this was the elite of the Goguryeo cavalry, they were very fast The ordinary infantry of the Great Sui in front of them was divided into countless small squares, as long as they saw that the infantry formation was defective, they immediately threw short spears and battle axes into it, as long as a gap was opened, the infantry without unified command could only accept the slaughter of the cavalry.

More cavalry crossed the infantry formation, brandished their weapons, and howled and charged towards Shan Xiongxin and his party, who were protected by the army of the Five Thousand Heavenly Sons.

The trebuchets at the head of the city had stopped throwing stones, and Shan believed that if the Goguryeo cavalry was defeated, more stones would recover the area.

With Yuwen Chengdu shouting loudly, rumbling footsteps sounded, and he crossed the shield array with half of the heavily armored guards of the Son of Heaven's army, and pounced on the surging cavalry with spears and battle axes.

Under the cover of the Eight Ox Crossbows, 2,500 guards of the Son of Heaven's army in heavy armor first responded to the enemy with strong crossbows in their hands, and their hands were very accurate, as long as they raised their hands, a Goguryeo cavalry would fall under the horse.

The foot soldiers of the Great Sui are already invincible in the world, let alone the king of soldiers among these soldiers.

It's just that in this world where cavalry is heavy, even if the foot soldiers defeat the enemy, they can only watch the enemy flee on horseback, and they can't get a happy annihilation battle, so the brilliance of the Great Sui foot soldiers always seems so weak.

In this world, only the heavy armored infantry can fight the cavalry head-on, a set of more than 60 pounds of heavy armor, so that they also have the strength to fight in the face of the heavy cavalry, so Yang Guangcai sent the 5,000 Tianzi pro-army guards over according to Wang Junlin's request.

In a short period of time, Yuwen Chengdu led 2,500 guards of the Son of Heaven's army in heavy armor to form a thin defensive line in front of the shield array, holding long-handled battle axes and war knives, pulling down armor and waiting for the arrival of Goguryeo's lightly armed cavalry.

At this time, the battlefield had become a pot of porridge, and the Sui army and Goguryeo people were fighting together everywhere.
