Under the city south of the Liao Tunnel.

Gongsun Xiu looked up at the Wei army flags at the head of the Liao Tunnel, and showed a malicious sneer on his face, and said to Yang Zuo: "Send iron-headed soldiers to charge with the engineers!"

Yang Zuo shouted: "Yes."

Immediately, he beat the drum himself. Eighty hundred iron-headed soldiers of the Yan army held two shields, and another eight hundred Yan army engineers each held short shovels and shovels, and a total of 1,600 people rushed towards the foot of the city with their stray arrows.

Hu Zun was shocked and suspicious: "What is the way to siege the city?"

The Wei army raised the rolling wood, threw the stones down, and the archers kept shooting arrows down. The Yan army's iron-headed army paired in pairs, the iron-headed soldiers resisted the enemy's wandering arrows, while the engineers frantically used short shovels to dig the soil at the foot of Liao Tun City. Eight hundred shovels flew over, all of which showed the spirit of Yugong moving mountains.

Yan army crossbowmen lined up on the city and shot towards the top of the city with a breaking sky, covering the Yan army dug at the foot of the city.

The two sides fought fiercely, and the iron-headed soldiers were covered by shields. The Wei army allowed the firing arrows to shoot down, and also blocked them.

Hu Zun was furious: "Does the dog thief in Yan army want to dig tunnels and enter the city? He is simply delusional, and he actually uses such a stupid method."

He looked at the rolling stones beside him, each weighing more than 200 pounds. He immediately picked up the rolling stones with both hands and smashed them down the city.

With a "collapse", the rolling stone hit the iron-headed soldier's shield, making a huge sound. The rolling stone weighing more than 200 kilograms and the drop of more than ten feet above and below the city were even more shocking.

The iron-headed soldier was smashed to pieces on the spot and fell to the ground. The engineer who was burying his head was exposed to the target without any protection and was shot and killed by the Wei army in the city.

Gongsun Xiu's expression was slightly moved, and he frowned and said, "This person seems to be born with divine power."

Yang Zun fought with Hu Zun for seven or eight rounds, nodded and said, "He is Hu Zun, one of Sima Yi's generals. The big knife is really splashing water. It's quite difficult for Bei Zhi to fight him for several rounds."

"The divine power is useless, and two fists cannot beat four hands."

Gongsun Xiu immediately ordered people to use bed crossbow to attack the city, suppress the firepower above the city, and solve the urgent problem for the engineers who were digging corners at the foot of the city.

Five days ago, the Wei army attacked the city and the Yan army defended the city.

Five days later, the offensive and defensive momentum changed again, and the fight was still invincible.

Hu Zun picked up another huge rock and was about to throw it down. Yang Zuo braved his rifle and fucked the sky, aiming it at him and shot it.

Hu Zun saw an arrow shot in his chest, blocking the huge rock in front of him. The arrow was flying away by the thick bullet of the huge rock. He was also hit by this force and was unstable. He took a few steps back. The huge rock could not hold it and fell to his feet, almost smashing his feet into a bloody and bloody state.

"Damn it, if I go down to the city, I will kill you with my own hands!"

His face turned pale, but his heart was frightened and he never dared to raise a stone again, so as not to become a living target again. He ordered the soldiers of the Wei army to step up their defensive offensive.

In his opinion, it was a dream for Yan Jun to dig out a tunnel.

Sima Yi couldn't see Gongsun Xiu's use of troops, and thought to himself: "Isn't this stupid person fighting like this? The soldiers have become living targets for our army. They compete on the battlefield and dig tunnels. Such behaviors are like killing soldiers."

Hundreds of Yan soldiers were killed or injured in the city. Gongsun Xiu sent a group of brave soldiers to pounce on them, pick up shields or shovels, and complete the unfinished military orders.

Soon, the Yan army engineers cleared out seven or eight feet of soil on the surface, and the shovel fell and knocked hard things. Everyone was overjoyed, and another round of excavation was heard, and a row of thick top wood supported under the foundation of the city wall leaked out.

The engineers pulled out the wine bags around their waists, which were covered with dark tincture oil, poured them all on the top wood, and then raised the torch to light them.

The flames immediately exclaimed, and a row of flames burned at the foot of the city for more than ten feet. The engineers added fuel to the fire again, and the fire spread rapidly, igniting all the top wood.

After doing all this, the Yan army's iron-headed soldiers and engineers raised their shields and retreated backwards.

Hu Zun was shocked and didn't understand why, "Why did you run away after setting the fire? What's the reason?"

Sima Yi took a look and immediately understood the trick. His face changed color: "I've been killed, run away! The south city is about to collapse!"

He ran downstairs without saying a word.

Hu Zun was clueless by these inexplicable words. Seeing Sima Yi, who was nearly 60 years old, running down the stairs as fast as a young man, he did not dare to stay and ran down the stone steps quickly.

The rammed earth under the foundation of the southern wall of the Liao Tunnel had already been sent to hollow out the soil before Gongsun Xiu evacuated it, and it had become a hollow area.

In order to prevent collapse during excavation, every time a place is hollowed out, the top wood is used as a jack to support the city wall. The foundation that is more than ten meters long is supported by the top wood.

The Yan army engineer dug out the buried loose soil, exposed the top wood, and immediately added oil and ignited the fire, burning the only support on the wall foundation.

The flames became more and more vigorous, and soon the wooden stakes were burned to pieces, and as the wooden stakes supporting the wall were cut off, the Wei army on the southern city tower felt the earth shaking for a moment, and couldn't help but sit down to the ground.

Immediately afterwards, dust flew with a "boom", the extremely thick southern wall of the Liao Tunnel collapsed, and all the Wei troops, who were unable to escape, were buried alive.

A huge gap collapsed on the south wall, which was more than ten meters wide. The collapsed wall pieces were piled up between the dilapidated walls that had not yet collapsed and could be pulled, making it a small slope of the earthen mountain that could be easily climbed.

Yang Zuo was stunned and said, "This - this is too amazing, right? Your Highness, you, you have a little trick and you will destroy the wall!"

Not only him, but also all the Yan army and Wei army were shocked to fall.

Sima Yi ran more than ten feet away without looking back. The city wall behind him collapsed immediately, the earth was shaking, and the heavy waves of air pushed dozens of feet away, lifting him to the ground.

Fortunately, he fought all year round. Although he was nearly 60 years old, he was still agile. He got up tremblingly and turned around and the city wall had collapsed.

Hu Zun, whose face was covered with dust, looked at the collapsed city wall with lingering fear, his mouth twitched, and said tremblingly: "This - what's going on? What magic did he use?"

"Not a witch."

Sima Yi patted the dust on his shoulder and frowned and said, "It was the firewood under the cauldron. I fell into this kid's plan. I deliberately threw down a Liao Tunnel City and occupied it for me to occupy it. In fact, I had already hollowed out the base of the wall base. The top wood supporting the wall base was burned off, and the wall would naturally collapse."

The dust slowly dissipated. Gongsun Xiu saw that the city wall finally collapsed, and immediately ordered: "Be the first to climb the earth slope and take up the place for me!"

Yang Zuo took the lead, and five thousand Yan troops behind him advanced in unison, and the crossbowmen shot feather arrows into the city at a rapid speed.

Hu Zun scolded the Wei army to block the Yan army's attack on the city. He knew that although the wall had collapsed, the earth slopes that were several meter high were a commanding height. Only by taking the lead could we grasp the situation, and we also followed the horse to climb the earth slope.

The two met on the spot. In order to avenge the previous revenge, Yang Zuo swept across the horse's spear and shot: "A traitor, take me first!"

Hu Zun dodged one after another and also fought back with a spear.

The two of them fought equally, and they rode their horses back and forth on the earth slope.

The twelve-meter-wide slope is quite narrow, and there are not many people standing at all. One hundred people on both sides will be blocked.

The Wei army was brave and good at fighting, and had been practicing combat for decades. However, the Liao Tunnel was broken through the city wall, and the morale of the army was deteriorated for a while. The Yan army was as powerful as a rainbow, and had already lined up in front of them, and was very willing to look down on death.

In the first round of charge, both sides suffered damage, and then one after another, all fighting for the dirt slope.

Yang Zuo took advantage of the chaos and stabbed Hu Zun in the left arm. He suddenly pulled out the spear. The spear head was covered with blood. Hu Zun could not stop it, so he had to remove the earth slope.

The Yan army was very powerful and rushed into the city. The Wei army was shocked and could not line up for a while.

Sima Yi sent out the supervision team and lined up three hundred steps away from the earth slope. Those who dared to retreat from the earth slope were killed. He knew very well that if the Yan army was allowed to attack the city from the earth slope, the threat would be obvious.
