Tonight was cloudy, and heavy dark clouds covered the sky. It was dark inside and outside the city. Yeluna was also standing on a big rock, watching the thousands of troops slowly climbing up the mountain road.

The mountain road is about one mile long, less than two meters wide, with a slope of about forty-five degrees, and there are cliffs on both sides. If there are rolling wood and stones on it, there is almost no way to escape. Of course, if your body is close to the cliff, you may be able to escape.

There were about 3,000 Liao soldiers attacked at night. This was the experience summarized by the Liao army after the failure of two attacks. There were too many people and it was inconvenient to advance and retreat. It was simply massacred by the Song army. The number of people was too small, and the attack would be weak. Three thousand people were the most suitable number. Since the number of people could be guaranteed, half of the space could be left below.

The soldiers held their shields and moved up step by step carefully, trying not to make any sound to prevent them from being heard by the defenders on the city gate.

Just when there were three hundred steps away from the city, several soldiers suddenly screamed at the same time.

"Ah" The shrill screams shocked the quiet night.

"What's going on!" asked the Liao army commander angrily.

"There are thorns on the ground!"

Immediately afterwards, another soldier screamed, and several other soldiers also stepped on the thorns, and the long spikes pierced into the soles of their feet. The severe pain made them unbearable.

At this time, a Song army soldier shouted on the top of the city. Seeing that the Liao army could not hide, the general of the Liao army waved his sword and said, "Kill me!"

"Kill!" Three thousand Liao soldiers jumped up and ran towards Chengguan.

‘Dong!Dong!Dong!’ There was a loud drum sound on the top of the city. The soldiers resting on the top of the city stood up one after another, opened their bows and arrows to shoot into the darkness, and the rolling wood and stones also smashed down like raindrops.

The collision sound of ‘Boom! Boom!’ was mixed with a scream.

"Stop shooting!" Yao Sheng shouted, and all the soldiers stopped shooting.

Yao Sheng turned around and said to several soldiers: "Fire an iron fire thunder!"

The crossbow had already been in the strings, and two soldiers held a sixty-pound iron fire thunder and placed it on the trough rack. Everyone dodged away, and one of them pulled out the thunder hat and lit the fuse inside.

The fuse burned and gradually burned to the bottle mouth. The iron fire thunder had to burn for a while, but as long as it was guaranteed that it would not be extinguished due to impact, it could be fired.

"Start!" The brigade coach next to him gave the order, and the soldier pulled the hanging knife below.

With a muffled sound, the iron fire thunder was projected out.

In the darkness, the iron fire and thunder fell to the ground, rolling towards the mountain, and all the soldiers on the top of the city covered their ears and squatted down.

However, the Liao army took advantage of the short-term opportunity of the Song army to stop shooting and rushed up, less than a hundred steps away from Guancheng.

At this time, a large black ball with white smoke hit the crowd. Several soldiers dodged without rushing and were hit and fell to the ground.

Before the Liao army soldiers could respond, the iron fire thunder burst out with a bright red light, exploding in the dense crowd.

The powerful air waves lifted dozens of soldiers into the air. The nearest Iron Fire Thunder, more than a dozen soldiers were blown into pieces. The shock waves killed soldiers farther away. Countless soldiers were injured by splashed iron sheets and iron nails. More people were deaf in their ears and lay on the ground in pain.

The soldiers on the mountain road were too dense and it was difficult to dodge. A single iron fire thunder killed and injured more than 500 people. The soldiers behind were so scared that they turned around and fled down the mountain.

The smoke gradually dissipated, and the sky was filled with a pungent bloody smell. Even the city was a hundred steps away and could smell this disgusting smell.

At the foot of the mountain, Yeluna was also stunned as the Liao soldiers retreated. He couldn't help but sighed and turned to the soldiers and said, "Tell me my order to General Yelu Xinfeng. First, don't feed black beans to the war horses; second, send 5,000 people to the valley to search for everything that can be eaten; third, horses that died in battle can be eaten."

He had to consider the most serious food issues.

In the chessboard deployed by Fan Ning, in addition to the three-step big chess in the East China Sea, Xixing and Taiyuan City, there are many small chess games, such as capturing Loufan Pass, capturing Juehua Island, and starting to build Ningyuan City. For example, hundreds of 10,000-stone ships arrived outside Pingzhou, showing signs of landing in Pingzhou.

Xiao Susa, who was left behind in Nanjing, knew that 80,000 troops were buried in the Bohai Sea. He was extremely frightened. The first thing he considered was to protect the retreating channel, fearing that the Song army would cut off the ties between Youzhou and Liao Kingdom, and urgently transferred the 80,000 troops from Nanjing Road to defend Pinglu to Youzhou.

Just as Nanjing Road contracted its defense line and all garrisons were transferred to Youzhou Hepinglu, another move began to quietly walk out.

An army of 10,000 people, led by the commander Wang Qigong, crossed Baigou and was secretly advancing west along Yishui.

Fanning's goal in the first phase was to recover Youyan. In order to achieve this goal, he had to cut a stake in Youzhou in advance, which was also a springboard.

After thinking for a long time, Fan Ning still focused his attention on Yi County. On the one hand, Yi County's own defense conditions are relatively good, easy to defend and difficult to attack. On the other hand, Yi County is close to Zhuozhou and can take down Fanyang County, the southern gate of Youzhou at any time. The third reason is that the Liao army did not have many troops in Yi County, and most of the troops attacked Yanmen Pass. After a defensive crisis occurred on the eastern front, Xiao Susa, the left-behind Liao army in Nanjing, transferred the 10,000 Liao troops attacking Yanmen Pass to Pingzhou.

There were only one thousand defenders left in Yi County, and with these thousand people, they could not defend Yi County. What's more, when the Song army evacuated Yi County, they had deliberately left loopholes for the next attack on Yi County.

Ten thousand soldiers hid in a hidden valley in Yizhou and hid for eight days. Just when their food was about to end and they had to return to Hebei, that afternoon, the chief general Wang Qigong received news that the 10,000 Liao troops besieged Yanmen Pass retreated east from Yi County.

This news made Wang Qigong very excited. He punched the stone wall hard, and survived in a desperate situation! The Eastern Front's coercive strategy was successful.

Wang Qigong immediately ordered: "The whole army sets off and heads to Yi County!"

Ten thousand troops marched quickly to Yixian, fifty miles away with the last two days of dry food. As soon as the sky got dark, the team arrived in Yixian.

A few miles away, Wang Qigong looked at Yixian, located halfway up the mountain in the distance. He unfolded a drawing and could vaguely see it clearly under the moonlight.

The water source of Yi County is mountain spring water flowing from a high place, gathering a stream and river running through the whole city, flowing in from the north of the city, flowing out from the south of the city, and finally flowing into Yishui.

The stream is about one meter wide, not very deep, about three feet away, and flows out from the south city.

Like all cities, the streams and rivers in Yixian also opened a waterway below the north and south city walls, and then installed a thick iron fence. The end inserted into the water was extremely sharp, making it difficult for the Song army to enter the city by diving.

But the Liao army guarding the city did not know that after Yang Wenguang occupied Yi County, he tampered with the waterway in order to capture Yi County next time. He ordered the soldiers to dig the waterway in the North City four feet deeper, lay stone slabs on it, and sprinkled with gravel. It looked no different from before, but as long as the stone slabs were removed, the soldiers could sneak into the city directly from the waterway.

Yang Wenguangzhi chose all the way to the North City because there were piles of rocks outside the North City, and there were cliffs after walking dozens of steps. The ground was bumpy and uneven, which was very unfavorable for siege. More importantly, the military camp in Yi County was in the south, so even if it was discovered by the Liao army, it would be difficult to come and support in time.

One hundred elite soldiers were already accurate. They stood close to the city, and there were several soldiers guarding the city patrolling back and forth at the top of the city, but it seemed very slack, and it was more like a routine patrol.

Just at the corner of the city wall, the commander Chen Hua led 3,000 soldiers to gather here, but at this time, Chen Hua had a new idea.

The secret passage left by Yang Dutong was only used in extreme situations, that is, it was only used when the city wall was tightly defended so that they could do nothing.

But now Chen Hua found that there were almost no soldiers patrolling the east city. They could climb the city directly, so why bother going to the waterway?

Chen Hua had the right to deal with the situation beforehand, so he immediately stopped the hundred soldiers who were preparing to dive, and quickly hung up more than a dozen rope ladders. Thousands of soldiers quickly climbed up the city along the rope ladder.

There was quiet on the top of the city, and only two soldiers patrolled above the city gates. Song soldiers rushed forward and were immediately discovered by the patrol soldiers. The defenders shouted, and the alarm bell rang at the top of the city.

The soldiers who heard the alarm bell in the military camp rushed out of the military camp in panic, but the dense rain of arrows shot towards them. The Liao soldiers screamed and fell down. The remaining soldiers retreated back to the military camp and used the fortifications such as the walls of the military camp to shoot at the Song army.
