In the early morning, Yuan Gaisuwen inspected outside the East City. The biggest problem here was that the ground was uneven, but there were rocks and deep pits. It was difficult to siege the city. It could be seen that the Khitan did not attack from both sides. However, after entering about two hundred steps close to the moat, the ground became flat, and the problem of siege was not big. More importantly, Yuan Gaisuwen found that there were not many trenchers on both sides of the east and west, and it was far from as dense as the north and south city walls.

Although Yuan Gai Suwen was waiting for the siege weapons sent by Yancheng, he also wanted to know the defense capabilities of the Sui army to defend the city. He didn't have to siege a large-scale attack. It was necessary to test the attack once. It was necessary to touch the Sui army's background.

Thinking of this, Yuan Gaisu Wenling said: "Send the second order to stop preparing, and attack the city in half an hour!"

This time, the Goguryeo Western Expedition army mainly came from local troops, with a thousand people as one local battalion. Yuan Taizuo also organized a centralized organization, with five local battalions as one stop, with about five thousand people, which was equivalent to the army in the Sui army. The leader was called Duhou, and there were five battalions below, and each battalion was called Qianyong.

The Goguryeo army's weapons were mainly spears, including copper spears and iron spears. They were wearing leather armor and slats, and their combat power was very strong.

Half an hour later, drums were heard outside the East City, and five thousand soldiers gathered quickly, shouting and killing kept ringing from the army, with murderous intent. At the same time, a low trumpet sounded from the head of Liucheng City. The large group of Sui troops gathered from the East City from all directions, and the situation of the enemy attacking from the East City was already very obvious.

There are indeed not many catapults on the East City, only thirty, far less than the one hundred and twenty in the South City. This is because large siege weapons such as ladders cannot be driven outside the East City, and the enemy cannot organize large-scale attacks. Even the attack is a small-scale tentative attack, so there is no need to deploy too many defensive weapons.

The deployment of the Sui army was not wrong. Goguryeo had indeed not many attacking troops, only five or six thousand people. Yang Shankong immediately judged that this was just Goguryeo's tentative attack. Since it was a temptation, he certainly would not realistically realize his true strength.

Yang Shanhui immediately ordered: "Send three thousand Sui troops and three thousand militia soldiers to defend the East City, and the rest of the troops returned to guard the area and wait for my order to transfer."

Although Yang Shanhui was the prefect, he was undoubtedly a master who was very good at defending the city. He mixed regular soldiers and militia to defend the city, combining the virtual and the real, making the Goguryeo people unable to understand the true strength of the Sui army.

In addition, Yang Shanhui also wanted to try the ladder-breaking technique and fire attack technique that they had just successfully trained. These five thousand Goguryeo troops came just in time.

The defenders on the head of the Dongcheng City kept changing their formations. Thirty catapults had entered a state of preparation. Three thousand soldiers were fighting for bows and crossbows, ready to fight. Thousands of militia soldiers transported the rolling stones and haystacks to the East City Wall. Although everyone was sweating, their faces were full of faith in victory.

At the same time, the Goguryeo army under the city also entered the final stage of assembly. Compared with the Khitan army, the biggest feature of the Goguryeo army is that their team is neat. They are not fast in pace, but their marches are uniform and uniform, revealing a powerful combat power. The expressions of several Sui generals on the city wall are solemn. If they leave the city and fight with the Goguryeo army, they will probably fail, not the Goguryeo army.

"Prince, throw out the thorns!" General Lu Chifeng asked the prefect Yang Shanhui.

Yang Shanhui shook his head. Although they had 30,000 poisoned thorns in their hands, Yang Shanhui was worried that once the Goguryeo people collected these thorns, they might be unlucky Sui cavalry in the end. He could not just try to be happy for a while, but had to consider the overall situation. This is the difference between the prefect and the general. The prefect will consider the problem longer.

"Prepare the boulder!"

The Goguryeo army was walking in the uneven rocky land and was almost entering the attack range of the catapult.

On the top of the city, 30 Sui army's catapults began to squeak open, and huge rocks were placed in the iron net bag. After the first battle with the Khitans, Li Chun adjusted the arm distance of the new catapult and set up a clever lever to greatly increase the projection frequency of the catapult and become more solid.

The stones as big as millstones were put into the throwing bag. At the command of Lu Chifeng, thirty trenchers were fired at the same time. Thirty huge rocks were thrown high, rolling in the air, drawing an arc, and smashing them into the dense crowd.

"Boom!" There was a loud noise from the ground, and screams were everywhere. Several Goguryeo soldiers were unable to avoid it and were smashed into meat pie by huge rocks. The huge inertia caused the stones to roll in the crowd, extremely rapid, and rolled out more than twenty steps in a row. Goguryeo soldiers desperately dodged to both sides, but more than a dozen people died under the collision of the huge rocks, and more than twenty people were injured, with broken bones and broken tendons, and wailing sounded.

Immediately after the second and third rounds, the fourth round of the catapult was shot. Accompanied by the Sui army's crossbow, arrows on the top of the city were like rain, and heavy casualties were killed and injured. Every huge rock was hit, which would bring dozens of casualties. It was simply a machine to massacre people, bringing a catastrophe to the Goguryeo army.

The role of the catapult in defending the city and siege war was unparalleled. In the Three Kingdoms era, the catapult was an essential weapon for the army to siege and defend the city. In the Battle of Guandu, the Cao army used hundreds of powerful catapults to destroy tens of thousands of Yuan's army, laying the foundation for the final battle of Guandu.

The same is true in Goguryeo. The Sui army used the most advanced catapult in the world, causing huge damage to the attacking Goguryeo army. The battlefield was full of corpses, with flattened bodies everywhere, smashed heads, blood flowing into a river, and dyeing the smashed stones red.

But the Goguryeo army was not overwhelmed by the cruel blow of the catapult. After paying the price of nearly a thousand casualties, they finally rushed to the east city. Arrows were raining on the top of the city, and Goguryeo soldiers raised their shields to greet them, and people kept getting caught in arrows and falling.

As long wooden boards were built on the moat, siege ladders began to hang on the city walls, and all the eighty siege ladders carried by the Goguryeo army were put into battle.

Yuan Gaisuwen rode a horse and stood on a slope two miles away, watching his army attacking Liucheng. The Sui army's sharp catapult was as expected, and he didn't care about the casualties caused by the catapult. He was concerned about the defense level and specific defense methods of the Sui army.

The appearance of the catapult indicates that the Sui army had long-range defensive weapons, and the Sui army's catapult was able to throw five rounds in a short 200-step running distance, which was more than double the catapult they seized before. This made Yuan Gai Suwen secretly shocked, but at the same time it also aroused his curiosity. How powerful is the Sui army's defense?

As a qualified commander, knowing oneself and enemy is the most important part. To understand the opponent's background, you must pay a price. Yuan Gaisuwen is very clear about this. He is ready to sacrifice these five thousand soldiers to understand the defense details of the Sui army.

"Bang the drum to urge the battle!" Yuan Gaisuwen shouted loudly.

‘Dong!Dong!Dong!Dong!’

The huge and dense sound of war drums echoed on the battlefield, urging the siege of Goguryeo soldiers to launch a fierce attack on the front of the city.

The rolling wood and stones on the top of the city fell like hail. Teams of soldiers screamed and rolled down the ladder and fell into the trench covered with spikes. The trench was filled with corpses of tragic deaths, and many undead soldiers were stuck in the spikes and howled, which was a terrible sight.

At this time, the soldiers on the top of the city lit torches, and then dozens of large haystacks were thrown down to the city. The torches were thrown on the haystacks under the city. As a large number of grass groups and shrubs were thrown down by the soldiers, the bottoms of dozens of siege ladders began to burn. The Goguryeo soldiers on the siege ladder were frightened and climbed up desperately, but were ruthlessly pierced by the sharp spear of the Sui army soldiers and screamed and fell into the fire below.

Many soldiers could not stand the scorching fire, jumped off the siege ladder, and most of them fell into the trenches, facing another kind of death.

More and more haystacks were thrown down, and a sea of ​​fire gradually formed on the city walls. Countless people were ignited by the fire and became firemen. They opened their arms and ran back, wailing and running back. Without taking a few steps, they fell to the ground. The fire burned them to the point of curling up.

Before he could even use the combination of the fork claw ropes to break the ladder, the Goguryeo people's offensive was completely swallowed up by the fire. The Goguryeo soldiers watching the battle in the distance were so scared that their faces were pale and their legs were trembling. Even the main general Yoon Gassuwen was stunned. He had never seen such a tragic fire in the city defending.

Finally, he sighed a long time and shouted: "Get off!"

The bell of withdrawal rang, and more than 2,000 Goguryeo soldiers who were scared turned around and ran towards the camp.
Chapter completed!
