It was cloudy tonight, heavy dark clouds obscured the sky, and it was dark inside and outside the city, and Jeruna also stood on a large rock, coldly watching the thousands of troops slowly ascend along the mountain road.

The mountain road is about a mile long, less than two zhang wide, the slope is about forty-five degrees, and there are cliffs on both sides, if there are rolling logs and rocks falling on it, there is almost no way to escape, of course, if the body is close to the cliff, you may be able to escape.

There are about 3,000 soldiers of the Liao army in the night attack, this is the experience summed up after the two failed attacks of the Liao army, there are too many people, it is inconvenient to advance and retreat, it is simply slaughtered by the Song army, the number is too small, the attack will be powerless, 3,000 people is the most suitable number, since the number of attackers can be guaranteed, half of the space can be left below.

The soldiers held their shields and carefully walked upward, trying not to make any noise to avoid being heard by the defenders at the gates.

Just when they were still three hundred paces away from the city, several soldiers suddenly let out screams at the same time.

"Ahh

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

"There's thistle thorns on the ground!"

Then another soldier screamed, and several other soldiers stepped on the thistle thorn, and the long spike pierced the soles of their feet, and the pain was so intense that they couldn't bear it.

At this time, there were Song soldiers shouting at the head of the city, and the main general of the Liao army saw that he could not hide it, and waved his sword, "Kill me!" ”

"Kill!" Three thousand Liao soldiers jumped up and rushed towards the city pass.

'Boom! Boom! Boom! The drums beat loudly at the top of the city, and the resting soldiers at the head of the city got up one after another, and shot their bows and arrows into the darkness, and the rolling logs and stones rained down.

'Boom! Bang! The sound of the impact was mixed with a scream.

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

Yao Sheng turned back to a few soldiers and said, "Launch an iron fire mine!" ”

The ballista had already been wound, and two soldiers were holding a sixty-pound iron fire mine on the trough rack, everyone dodged, and one pulled out his thunder hat and lit the fire rope inside.

The fire rope sneered and burned, gradually burning to the mouth of the bottle, and the iron fire thunder had to burn for a while, but as long as it was guaranteed that it would not be extinguished by impact, it could be launched.

"Launch!" The brigade commander next to him gave an order, and the soldier pulled the hanging knife below.

'Bang! With a muffled sound, the iron fire thunder was projected.

In the darkness, the iron fire and thunder fell, and the bones rolled down the mountain, and all the soldiers at the head of the city covered their ears and squatted.

However, the Liao army took advantage of the Song army's brief opportunity to stop shooting and rushed up, less than 100 steps away from Guancheng.

At this time, a large round ball with white smoke and swarthy black smashed into the crowd, and several soldiers were not in a hurry to dodge and fell to the ground.

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

The powerful air wave lifted dozens of soldiers into the air, and more than a dozen soldiers were blown to pieces when they were close to the iron fire mine, and the shock wave shook the soldiers farther away to death, countless soldiers were injured by the flying iron pieces and nails, and more people were deaf in both ears and lying on the ground in pain.

The soldiers on the mountain road were too dense to dodge, and an iron fire thunder killed and injured more than 500 people, and the soldiers behind were so frightened that they turned around and fled down the mountain.

The smoke gradually cleared, and the air was filled with a pungent smell of blood, and even the city head a hundred paces away could smell this disgusting smell.

At the foot of the mountain, Yelu Na was also stunned as the Liao soldiers retreated, he couldn't help but sigh, turned back to the soldiers, and said: "Pass my order to General Yelu Xinfeng, first, don't feed the war horses with black beans; second, to send five thousand men into the valley in search of everything that could be eaten; Thirdly, horses killed in battle can be used for food. ”

He had to think about the most serious food problem.

In the chessboard deployed by Fanning, in addition to the three big chess moves of Donghai, Xicheng and Taiyuan City, there are also many small chess games, such as the capture of Lou Fu Pass, such as the capture of Juehua Island, the beginning of the construction of Ningyuan City, and the arrival of dozens of large ships of 10,000 stones off the coast of Pingzhou, there are signs of preparing to land in Pingzhou.

Xiao Susa, who stayed in Nanjing, knew that 80,000 troops were buried in the Bohai Sea, and his first consideration was to protect the passage of the northern retreat, lest the Song army cut off the connection between Youzhou and Liao, and urgently transferred the 80,000 troops in Nanjing Province to defend Pinglu to the line from Youzhou.

Just when Nanjing Road contracted the defensive line and the garrisons from all walks of life were transferred to Youzhou and Pinglu, another move began to quietly come out.

An army of 10,000 men, under the leadership of Wang Qigong, the commander of the capital, crossed Baigou and was secretly marching west along Yishui.

Fanning's goal in the first stage is to recover Youyan, and in order to achieve this goal, he must drive a stake in Youzhou in advance, which is also a springboard.

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 Fanyang County, the southern gate of Youzhou, at any time, the third reason is that the Liao army does not have many garrisons in Yi County, most of the troops went to attack Yanmen Pass, and after the defensive crisis on the eastern front, Xiao Susa, who stayed in Nanjing, transferred the 10,000 Liao troops who attacked Yanmen Pass to Pingzhou.

And there are only 1,000 defenders left in Yi County, and with this 1,000 people, they can't hold Yi County, not to mention that when the Song army evacuated Yi County, it had deliberately left a loophole for the next attack on Yi County.

10,000 soldiers hid in a hidden valley in Yizhou for eight days, just when they were running out of food and had to return to Hebei, that afternoon, the main general Wang Qigong got the news that the 10,000 Liao troops besieging Yanmen Pass retreated eastward from Yixian.

This news made Wang Qigong very excited, and he smashed his fist on the stone wall, and he was in a desperate situation! The strategy of coercion on the Eastern Front succeeded.

Wang Qigong immediately ordered: "The whole army set off and go to Yi County!" ”

10,000 troops, carrying the last two days of dry rations, marched quickly to Yi County, fifty miles away, and as soon as it was dark, the team arrived at Yi County.

A few miles away, Wang Qigong looked at Yi County, which was halfway up the mountain in the distance, and he unfolded a drawing, which could be vaguely seen in the moonlight.

The water source of Yi County is the mountain spring water that flows down from the heights, and a stream runs through the whole city, flowing from the north of the city, flowing out from the south of the city, and finally flowing into the Yi water.

The stream is about a zhang wide and not very deep, about three feet, and flows out from under the southern city.

Like all cities, the river in Yi County was built with a waterway under the north and south walls, and then a thick iron fence was installed, and 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 defending the city did not know that after Yang Wenguang occupied Yi County, in order to capture Yi County next time, he did something in the waterway, he ordered the soldiers to dig the waterway in the north city four feet deeper, paved with stone slabs, sprinkled with gravel, it looked no different from before, but as long as the stone slabs were removed, the soldiers could dive directly into the city from the waterway.

Yang Wenguangzhi chose to be in Beicheng, because outside the Beicheng is a pile of rocks, dozens of steps away is a mountain cliff, the ground is bumpy, which is very unfavorable for attacking the city, and more importantly, the military camp in Yi County is in the south, so even if it is discovered by the Liao army, it is difficult to come to support in time.

A hundred elite soldiers were exactly ready, and they stood close to the city, but there were a few defenders patrolling back and forth at the head of the city, but they seemed very lax, more like a routine patrol.

At the bend of the city wall, the commander Chen Hua led three thousand soldiers to assemble here, but at this time, Chen Hua had a new idea.

The secret passage left by Yang Dutong was only used in extreme cases, that is, when the city head was heavily defended, leaving them with nothing to do.

But now Chen Hua found that there were almost no soldiers patrolling the head of the eastern city, and they could directly climb the city, so why bother to take the waterway again?

Chen Hua had the right to dispose of the situation on the spot, he immediately stopped the hundred soldiers who were preparing to dive, and quickly hung up more than a dozen rope ladders, and thousands of soldiers quickly climbed along the rope ladders to the top of the city.

The city was quiet, only two city gates were patrolled by soldiers, the Song soldiers swarmed up, and were immediately spotted by the patrol soldiers, the defenders shouted and shouted, and the city immediately sounded the alarm bell.

The soldiers who heard the alarm bell in the barracks rushed out of the barracks in a panic, but they were faced with a dense rain of arrows, and the Liao soldiers fell down with screams, and the remaining soldiers retreated to the barracks, using the barracks' walls and other fortifications to shoot at the Song army.

At this time, an extremely strong man appeared outside the barracks wall under the cover of more than a dozen soldiers, and he threw himself into the barracks with a forty-pound iron fire thunder, only for a moment, there was an earth-shattering explosion in the barracks, and the smoke was thick, and the counterattack of the Liao army disappeared instantly, and thousands of soldiers rushed in and killed into the barracks........
