The low and powerful war drum sound was ringing, and ten thousand soldiers surrounded the huge cloud ladder and the nest cart slowly walked, but halfway through, the cloud ladder and the nest cart were difficult to continue. Below Yixian County is a slope. The center of gravity of the cloud ladder and the nest cart is too high, especially the nest cart, which is very easy to overturn when pushed on the slope.

Yelu Kunping said angrily: "Pull the cloud ladder and the nest cart up for me."

The Liao soldiers had no choice but to whip the cattle and drag the nest cart and the cloud ladder slowly tow.

On the top of the city, seven thousand Song troops were ready. Yang Wenguang looked coldly at the Liao soldiers who were rushing towards him faster. He turned around and ordered: "Get ready!"

The Song army prepared tens of thousands of thick and short pieces of wood, each of which weighed at least fifty or sixty kilograms. This was a trick that Yang Wenguang learned from the people of Xixia. He threw it down from a high place. Rolling the wood is definitely a big killer.

The Liao army shouted amid the fierce drums and rushed towards the city and entered the four hundred step line. Generally speaking, entering the four hundred step line means entering the strike area at the top of the city, and crossbows and other things will be launched at this time.

Just after thousands of people ran across the four hundred lines, some people kept screaming and falling, some people stepped on the thorns, some people stepped on the thorns, and some people stepped on the thorns. When they stepped on the thorns, they only pierced the skin, but they were seriously injured when they stepped on the thorns, and were directly pierced by bamboo sticks.

However, the thorns in Yi County cannot be compared with Ba County. Ba County has scattered 200,000 thorns, while Yi County has only scattered 30,000, but tens of thousands of them have been made in the trap.

Although it brought psychological shadows to the offensive soldiers, under the supervision of the offensive drum, the offensive soldiers did not stop and continued to run.

Yang Wenguang narrowed his eyes and looked at the nest car that was getting closer. He immediately ordered: "Throw the rolling wood!"

Two soldiers raised the rolling wood and threw it down hard. The rolling wood rolled down the slope. The soldiers in the front found that the rolling wood was hitting the sky, which scared them to the ground. The rolling wood flew over their heads. Many soldiers behind could not dodge and were hit by the rolling wood.

The rolling wood that did not hit the soldiers continued to roll down the slope. Hundreds of strong cows that were pulling the nest cart and the cloud ladder were immediately smashed to pieces and their tendons were broken. The pulling force was lost. Several nest carts shook and fell backwards. The soldiers shouted and fled in all directions, but some people still couldn't escape. At least dozens of soldiers were pressed under the overturned nest cart and the cloud ladder and died on the spot.

"Stop!" Yang Wenguang raised his hand and stopped the attack of the giant wood.

When the enemy lies down, the killing effect of the giant wood attack will be significantly weakened. If it can cooperate with the soldiers and arrows to defend the city, it will be a good auxiliary method.

"Prepare soldiers and arrows!" Yang Wenguang immediately ordered.

Thousands of archers stood in the rear and were ready. In fact, the Song army used caltrops and horse pits to target siege infantry, but archers and cavalry of the Liao Kingdom.

The archers and cavalry of the Liao Kingdom were powerful. They shot arrows at high speed and could completely suppress the Song army throwing rolling woods on the top of the city. Therefore, it was necessary to deploy thorns and horse pits within the attack range of the Liao army's cavalry.

As for the archers, they shot arrows into the air behind the city and inside the city, and the arrows of the Liao army's archers could not affect them.

The Liao soldiers ran like a tide, getting closer and closer. Some people kept stepping on the caltrops and falling into the trap, but the large group of Liao soldiers gradually approached the city and entered seventy steps.

Yang Wenguang immediately ordered: "Throw the rolling wood!"

More than a thousand soldiers raised the rolling wood, and the first batch of more than 500 rolling wood was thrown down the city. They rolled and smashed towards the Liao soldiers who were rushing. The Liao soldiers caught them off guard and the rolling wood fell into the dense crowd, which immediately smashed the Liao soldiers to their bones and their tendons and shattered the skulls, and hundreds of soldiers were smashed over. Then the second batch of rolling wood flew towards each other, and the soldiers who came to their senses were lying on the ground.

Yang Wenguang immediately ordered, "Shoot!"

With a crisp sound of clappers, five thousand soldiers on the city head fired arrows at the same time. The dense arrows quickly formed a black cloud, flew into the air, drew an arc, and fell into the enemy like raindrops, and screams suddenly rang out.

The probability of being shot by arrows on the ground was even greater. For a time, the Liao army suffered heavy casualties. Soon, the second and third rounds, the fourth round of the soldiers and arrows flew towards each other again. The arrows were like rain, causing extremely heavy casualties to the five thousand Liao soldiers who entered the range of the soldiers and arrows. Almost all were injured, with more than 2,000 casualties and three thousand injured.

The Liao army could not hold back and turned around and ran. The overwhelming rolling wood was chasing behind. Soldiers were constantly being knocked down by rolling wood. The soldiers rushed out hundreds of steps before they broke out of the rolling wood's attack range.

Yelu Kunping was frightened to see behind. The Song army was not injured, but they suffered four or five thousand casualties. In the final analysis, the Song army was condescending and had the most favorable terrain. How could Yi County be able to capture it?

Deputy General Yelu Feng whispered: "As far as I know, Yi County is built on the mountain, and it is all backed by a stream of spring water on the mountain. If this stream of spring water can be cut off or led away, within ten days, the Yi County defenders will have to surrender."

Yelu Kunping was overjoyed and immediately asked two generals familiar with Yi County. One general said: "There is indeed a stream of spring water flowing into the county town on the mountain. There is a cliff above it. It is unlikely to lead it away. If you walk to the top of the mountain and block the spring, it is a feasible plan."

Yelu Kunping immediately ordered Yelu Feng to lead 500 people up the mountain to block the spring. This was a ruthless move to remove firewood from the cauldron. In fact, it was also Yixian's biggest weakness. Its terrain was higher and the water flowed to a low place, so it was easy for the enemy to catch the water source.

Sure enough, that morning, a stream flowing from the mountain into the city suddenly disappeared, and the water source in Yi County was cut off. Although Yi County had some spare water and there were a lot of ice in the ice cellar, these could not maintain the drinking water problems of 15,000 soldiers and nearly 20,000 soldiers for a long time, and lasted for seven or eight days.

The first crisis in Yi County came unexpectedly.

............

At night, Yang Wenguang and more than a hundred people stood in front of the ditches in the north of the city. A stream in the back mountain entered the city gate through this ditches. Because the mountains outside the north of the city were steep and steep, the enemy could not come, so the Song army was not worried that the water source would be cut off.

But now the stream has disappeared, and there are no enemy troops in the north of the city, which means that the Liao army has found the water source and blocked the water source.

Yang Wenguang's expression was particularly serious. This time he was careless and forgot that Yi County had been occupied by the Liao army for a long time. The Liao army knew better than him about the weaknesses of this county. Yang Wenguang knew in his heart that once the water source was really cut off, they had to break through.

Ma Wei whispered: "Elder General, let's break through tonight while the enemy is not ready! As long as you pass Yishui, the enemy cavalry will not be able to pursue us. We can at least protect 80% of our troops."

Yishui is ten miles south of the city. Although the enemy is a cavalry, they can only run ten miles before being discovered by the enemy. It should be said that Ma Wei’s suggestions are good, and if they break through tonight, they will be successful.

But the problem is that they are willing to give up the Yizhou that they finally seized?

Yang Wenguang pondered for a while and asked the county magistrate next to him, "Mr. Kong, there is no other way, such as we can dig wells."

Kong Ran shook his head sadly, "Don't joke, the soil layer is good, but there are stones below. I have been the county magistrate for four years and have never heard of Yi County being able to dig wells and get water."

Yang Wenguang thought about it again and said to Ma Wei: "You gather the army first, and I will see if there is any other way."

Ma Wei took the order and Yang Wenguang sent dozens of soldiers to the city to inquire if there was any other way to obtain water.

Yang Wenguang couldn't fall asleep all night. The blow came too suddenly. They had the upper hand, but were knocked out by the enemy's firewood from the bottom of the pot and turned the tables.

Yang Wenguang stood at the top of the city and stared at the Liao army camp in the distance. The barracks were also brightly lit. It seemed that the Liao army was also waiting all night, waiting for him to lead his army to break through.

Ma Wei walked forward quickly and reminded Yang Wenguang: "The old general is already five o'clock in the morning, so it would be too late if he didn't break through."

Yang Wenguang glanced at the Liaoying in the distance and said, "The Liaoying was not sleeping all night, which means they are ready. Do you think there will be no ambush by the Yishui River?"

Ma Wei was stunned for a moment, and then said: "But no matter what, breaking through early is better than breaking late. Once the enemy army arrives, it is probably difficult for us to break through."

At this moment, a soldier rushed over and bowed and said, "Old General, an old man said that there is still water source elsewhere."

Yang Wenguang was immediately overjoyed and asked hurriedly: "Where is the old man now?"

"On the north city!"

Yang Wenguang and Ma Wei rushed over and saw more than a dozen soldiers following an old man looking for something?

"Is it him?" Yang Wenguang walked up to him and asked.

Dutou hurriedly said, "It's this father-in-law. He happened to meet us when he went out early in the morning. He said that the water source had been cut off before, but they dug a well to solve it."

Yang Wenguang was stunned. There were stones below. Can you dig a well?

He walked up and asked, "Old man, can you dig a well below?"

The old man nodded, "Nowhere else, but there is one place that can."

He stroked his beard and said, "Thirty years ago, the canal also broke through. We dug hundreds of wells in the city, but all failed. But when we successfully drilled the well in one place, the water came out. There was not only a small stream in the mountain, but also a dark river, which were all connected. If the spring was blocked, the water volume of the dark river would increase."

The old man pointed in the middle, "If I remember correctly, it's here. After digging, there should be a stone slab under it. The well we dug should be under the stone slab, which may be a bit blocked."

Yang Wenguang immediately asked someone to dig the road, and indeed a stone slab was found below. He lifted it up and a dark hole appeared.

Yang Wenguang was very happy and dispatched hundreds of soldiers to dig together. At noon the next day, he dug a large pit three meters wide and one meter deep, and dug several feet again, digging a stone cave, and a spring water gushed out of the stone cave.
