After three days of rest, the drums of the Khitan camp sounded again, and another siege began. Because the northern city was covered with poisonous thorns and sanks, and the surfaces on the east and west sides were bumpy and siege ladders were difficult to support, the siege of the Khitan army was still concentrated in the south.

The Sui army had already concentrated all the catapults to the south, with more than 70 left to use, and there were also bed crossbows and stone cannons, but without nesting chariots and cloud ladders, the stone cannons were no longer effective. The Sui army simply abandoned them and concentrated their forces to use crossbows and arrows.

Looking at the Khitan army that began to gather quickly in the distance, Yang Shanhui said to Duan Xianda and Lu Chifeng: "The other party's ladder, trencher and nest car are gone, there are only siege ladders and siege rams. We are not afraid of siege rams. We mainly deal with siege ladders. The weapons given to everyone by Mr. Li, have you practiced in the past two days?"

The two bowed together and said, "We have set up a special team and can already use it skillfully."

"Okay! Whether we can defend the city is today's battle."

At this time, the vast Khitan army in the distance came to Nancheng. Despite the repeated painful lessons, the Khitans became smarter and thought of many ways to deal with the Sui army's thorns and foot pits. They cut down thousands of big trees and paved several roads with branches and wooden boards.

In addition, they placed the lush tree canopy on a large cart and let the cows pull it forward, thus forming a series of tree walls to resist the attacks of catapults and crossbows. The soldiers hid behind the tree walls. Although this running speed would slow down, the effect was released, weakening the attack power of the Sui army's catapults and crossbows.

The huge rocks roared and hit the ground, and the dust suddenly flew up, and the huge rocks rolled over. One of the huge rocks knocked over the ox cart. The huge tree canopy pressed the soldiers behind them underneath. The frightened ox broke free from the rope and ran on the battlefield like crazy.

Although the huge tree crown did effectively weaken the Sui army's casting effect, as it gradually approached the city wall, the tree crown and the ox cart would become an obstacle to the attack. Therefore, when the ox cart drove out of the attack range of the catapult, Khitan soldiers rushed out from behind the tree crown and ran towards the city wall.

At this time, a clapper sounded at the top of the city, and thousands of arrows on the city were fired at the same time. The dense arrows shot towards the Khitan soldiers rushing towards the rushing Khitan soldiers like a storm. The soldiers were caught and fell down, and thousands of Khitan soldiers also began to shoot arrows at the top of the city, and the arrows on both sides formed a dense net of arrows.

Siege ladders hit the city top, and the iron hook in front hooked the bricks on the wall at the city top. Khitan soldiers held their shields and climbed upwards. Wooden stones rolled down the city top, and siege soldiers kept screaming and falling from the ladder and falling into the trench below. However, Khitan soldiers' eyes were already red and they climbed up regardless of life and death.

At this time, two soldiers holding big axes rushed to the siege ladder and swung the axe to slash towards the ladder. This axe was made of the steel forging method of Modao. It was extremely sharp. It only took a few axes to cut the front end of the ladder. The iron hook and the ladder were separated. Several other militia soldiers hooked the siege ladder with iron chains and claws from the side and pulled the ladder hard. At the same time, several soldiers pushed out with steel forks. The siege ladder gradually tilted, and finally overturned. The twenty soldiers on the ladder made a series of screams, rolled to the ground, and most of them fell into the trenches.

This is the method Li Chun used to deal with the siege ladder. It is simple and practical. Three weapons: axe, fork and claw are used at the same time. In addition, the flying claws are controlled by iron chains, and the enemy soldiers cannot cut off even if they swing their swords. The key is cooperation. As long as the three groups of soldiers cooperate and understand tacitly, a siege ladder can be broken in just a moment.

As the siege ladders were easily broken by Sui soldiers, the attacking soldiers was extremely unfavorable. Gao Kaidao shouted anxiously: "Siege the ram!"

Five siege rams began to appear on the battlefield. This kind of siege ram is like moving flat-length pavilions, three zhang long, one zhang wide, and one zhang five feet high. It has wooden herringbone slanted tops on it, covered with raw cowhide, not afraid of fire, and four huge wheels below. The middle is made of iron chains. The siege ram is made of giant wood, about three zhang long, the bucket is thick, and the front end is sharpened and pig iron hits the head. The soldiers pull the siege ram to hit the city.

A giant siege ram has the power of ten thousand kilograms in one blow, but today this kind of siege ram is a large siege ram, not a giant type, and each blow has at least three thousand kilograms of impact.

In the early stage of the attacking ram, the ox was pulled forward by the bull, and when approaching the city wall, it was switched to using soldiers. Each attacking ram requires two hundred soldiers to control it, which can attack the city wall and the city gate.

In terms of using siege equipment, Gao Kaidao is more experienced than the Khitans. He had long seen that the Liucheng city gate was made of pig iron and could withstand heavy blows of ten thousand pounds. Their siege rams were ineffective, and the opponent's suspension bridge was pulled up high, like a protective plate blocking the city gate. The siege gate was obviously unrealistic.

Gao Kaidao gave up the city gate and instead considered attacking the city wall. If they could penetrate the city wall, perhaps they still had a chance.

When Yang Shanhui saw the siege rifle coming slowly, he had already entered the attack range of the catapult, and immediately ordered, "Use the catapult to destroy the siege rifle!"

Eighty catapults creaked away and shot out suddenly. Pigeons roared at the five siege rams. There were continuous huge rocks hitting the siege rams, stirring up rolling dust and terrifying. Several snatched cows were blindfolded and they didn't know the danger. However, the hundreds of soldiers next to the siege rams were all scared and their faces were pale and their legs were weak.

At this time, a huge rock hit one of the siege rams, and the roof was smashed to pieces. The siege rams rolled out, and the hammer was thrown out, smashing more than a dozen soldiers to death on the spot. Cheers suddenly sounded on the top of the city.

Another siege ram was hit, the shaft was broken, and it rolled twice, and suddenly fell to the ground to the sky, unable to move. Then the third siege ram was hit by a huge rock, the chain fell off, and the hammer body rolled out.

In the end, there were only two siege rams leaning against the city wall and being pushed forward by the soldiers. Yang Shanhui had already prepared. With his order, he threw hundreds of bundles of hay on the top of the city and buried the siege rams. Torches were thrown down. The hay was quickly ignited and the fire spread very quickly. In a blink of an eye, the rams surrounded the siege rams. Hundreds of Khitan soldiers were so scared that they turned around and fled. Arrows on the top of the city were scattered. Khitan soldiers were all shot into the ground and were engulfed by the fire together with the siege rams.

The five siege rams were wiped out, and most of the siege ladders were lost. The soldiers who siege were killed and injured. Seeing that there was no hope of siege, Su Zhi had to sigh and "Get off!"

‘Dang!Dang!Dang!’ The bell to withdraw the troops rang again, and the tormented soldiers turned around and ran towards the camp. The siege failed again, and cheers suddenly appeared above the city.

Su Zhi and Gao Kaidao came to Dahe Duluo to apologize. Before they could speak, Dahe Duluo pointed at Su Zhi and ordered, "Tie me!"

More than a dozen soldiers rushed forward and pressed Su Zhi down. Su Zhi shouted: "No sin!"

"Not guilty?"

Dahe Duluo said coldly: "You attacked the city twice before, but this time you didn't even touch the battlement. Do you think I'm blind and can't see it?"

"That's because the Sui army found a way to deal with the city ladder. Nearly half of the Beishi army were killed or injured. Am I still deliberately slacking off?"

Everyone pleaded for Suzhi, and Dahe Duluo's eldest son Dahe Mo came forward and whispered to his father: "Killing him will affect our relationship with the Xi people, and my father must be cautious."

Of course, Dahe Duluo knew that Su Zhi was the chief of the Xi people and could not be killed. He just deliberately made a gesture and pushed the blame for the defeat to Su Zhi. He snorted heavily, "Well, for the sake of the generals pleading for you, I will not punish you for now, and I will settle the accounts with you when I look back."

He waved his hand and said, "Get back to the camp!"

Tens of thousands of Khitan troops stopped and lined up to return to the camp. On the top of the city, Li Chun walked forward and said to Yang Shanhui with a smile: "Their siege weapons are almost exhausted. If they still have to attack the city, they can only cut trees to make simple ladders. I don't want to underestimate the Khitan craftsmen, but in the past few days, they used all the siege weapons left in Liaodong by the Great Sui Dynasty. This shows that their manufacturing level will not be very good. A good siege ladder will take at least one month to make. If it is completed in a hurry, it will be difficult to fit the wooden ladder firmly. This kind of ladder will collapse in one blow."

Yang Shanhui nodded and said, "Actually, I am no longer worried about the weapons of siege. From today's battle, it can be seen that they obviously do not have the fighting spirit and morale they had before. The Khitans themselves are not good at siege cities, but are good at cavalry fighting. I guess they can no longer hold on."

After a moment, Yang Shanhui said worriedly: "Actually, I am more worried about the Goguryeo people. The Khitan greatly weakened our defense. If the Goguryeo army comes again later, how can we resist it?"
