When Wang Yi saw this scene on the mountain, he was distressed and deeply regretted his mistakes and carelessness. He then saw the remaining halberd soldiers carrying the door panels, launched another attack, and finally saved all the Qin troops after losing a dozen more soldiers. The Zhao army also focused on extinguishing the fire at the city gates, and resigned itself to the rescue operations of the Qin army.

This time the offensive ended in complete failure. Wang Ji ordered Mingjin to collect his troops, and all the wounded were sent to Jianzicheng, and then to Shangdang and Gaodu.

Two battalions prepared for a rush and a water attack were also in action. They requisitioned the stone axes of the people of Yi to go up the mountain to cut wood, and they also requisitioned the large baskets of the people of Yi to hold stones. Since the water level is not high, it is possible to wade in vain, and with a few baskets of stones it may be possible to block the river and divert the water to the city.

In charge of guarding the pass was a young hundred-man general, Li Mu. The Li clan is a large clan of the Bai people, and the Bai people are the great city of the Zhao State after Handan, and they enjoy the privilege of coinage together with Handan. Grandpa Li Dui was once a powerful minister of Zhao State, and King Wuling of Zhao was trapped and starved to death by him, and was named Fengyang Jun. His grandfather, Li Tan, had participated in the battle of Vaqi, made meritorious achievements, and is now in charge of the Bai people. Li Mu had just come out of office and was sent to the leather prison to garrison. Although it is remote, there are not many things to do. But the world is unpredictable, and the skin prison, which has always been fine, has become an important front line because of the Battle of Changping! Li Mu, who was only a teenager, was caught in the war in this way, and what was worse was that he was still disabled: his right arm was born contracture, he couldn't draw a bow, and he couldn't hold a sword.

Therefore, when Lian Po personally led the army to the leather prison to set up defenses, he wanted to remove Li Mu and replace him with someone else. However, Li Mu introduced his tactical vision to Lian Po: in this narrow space, the brigade could not play a role, and could only rely on small forces to fight. And he has been in the pass for a long time, and he is very familiar with everything here, and he has tactics in every direction, ensuring that he can consume a large number of Qin troops before the pass.

Seeing that the boy was right, Lian Po left him behind, but he wanted to replenish his troops and send a man of five hundred men to come. Li Mu said: "The general believes in the pastor, but he can entrust the military to the pastor, and if he fails, he will be blamed for the crime of the pastor." If it is entrusted to others, the pastor can go. Lian Po didn't want this kid to be so tough, thinking that he was Li Tan's little grandson, it was normal to be a little arrogant. At present, there are few confident people who are confident and many who are not confident, if Li Mu is confident, he might as well let him try. Anyway, the leather prison is not too important, in case it doesn't work, if you lose it, you will lose it, just for children to play with. So he supplemented his troops and asked Li Mu to act as a general of 500 people.

When the Qin army arrived, Li Mu did not send all these five hundred people to the city. This pass was not big in the first place, and there was no need to send troops to guard the northeast and southeast sides, so he only sent a hundred people to the city to defend the two walls, and the others waited in the camp to listen to his drums to go up to the city to support. From the barracks to the walls in all directions, there were no more than a hundred paces, and reinforcements could arrive in an instant.

On the first day of the siege of the city, he ordered his soldiers to shoot several archers of the Qin army; When the archers of the Qin army concentrated their fire, Li Mu ordered all the soldiers to hide against the wall, and the casualties were very small. However, the Qin army set fire to the city gate to Li Mu's surprise, he could not prepare in advance, so he could only wait for the fire to start, transfer a hundred soldiers, and douse the fire with water on both sides of the city.

The next day, Li Mu learned to be obedient, and saw that the Qin army was crossing the river under the cover of the door panel, so he simply did not make special blockades, but withdrew the soldiers to the far end, and waited for the Qin soldiers to get close before shooting fiercely, causing huge casualties to the Qin army.

In the past two days, Lian Po also watched the battle on the opposite mountain. Li Mu's successful defensive operations in the past two days were very appreciated by Lian Po. Every night he sent troops to replenish the casualties of the day and rescue the wounded; Replenish food and water, replenish arrows, and encourage Li Mu to fight hard! After repelling the two attacks of the Qin army, the soldiers of the Zhao army also had high morale and had great confidence in Li Mu.

On the third day, the Qin army attacked again, still charging under the cover of the door panels, and then threw straw bundles into the city gate and set fire to the city. Li Mu also concocted the same method, but this time, the halberd soldier who threw the grass bundle covered with a door panel, which effectively reduced the power of Li Mu's concentrated shooting. Moreover, the Qin army did not rush to retreat after lighting the fire, but concentrated the fire above the lit city gate and ordered the Zhao army to extinguish the fire in the upper city suffered heavy casualties.

Li Mu ordered the archers on both sides to shoot arrows outward, and on the other hand, regardless of the casualties, he asked the soldiers to water the city and the ground. Because the arrows of the Qin army were very dense, many soldiers were a little afraid, and Li Mu personally carried a water urn to the city to water, while encouraging everyone to climb the city bravely. After two landings, the fire was finally extinguished.

But before the Zhao army could catch its breath, the Qin army rushed up again, threw a bundle of grass, and set fire to the city gate again. This time was different from the last time, the outside was dry grass, and the inside was wet bundles of grass, not only was there fire, but the wet grass was not burning enough, and the smoke was billowing out, so that Zhao Jun could not approach at all.

Li Mu ordered the soldiers to water the city gates under the city and delay as much as possible. The archers in the city retreated beyond the smoke and fought back, and from time to time someone fell from an arrow. Although the Qin archers suffered greater losses, they still stubbornly shot arrows into the city. After a period of smoke, it abates. The Qin army rushed up again, threw hay, and lit the fire again.

The continuous efforts finally bore fruit, and about noon the fire at the gate changed from smoldering to open flames, when suddenly a strong wind blew, and the open flames turned into deflagrations, and the flames rose at once; The Qin army threw hay into the fire again, making the flames even more violent, and finally the flames lit the gatehouse.

Seeing this scene, Lian Po was very helpless to order Mingjin. Li Mu opened the south gate, and a group of soldiers left in an orderly manner and entered the narrow valley, and the wounded were all taken away. Li Mu led the archers to evacuate last.

Wang Ji saw Li Mu withdraw his troops from the mountain, and he did not instruct his troops to pursue. Because of the fierce burning now, the flames of the city gate began to spread to all the combustibles in the city: barracks, food, straw, arrows, weapons, and sundries...... So much so that the other gate (there were only two gates in the pass, one facing south and one facing west), the whole city was ablaze.

Wang Di's troops were insufficient, and he did not dare to go to fight the fire, so he could only watch the city be completely burned down. He sent the wounded soldiers back again, and instructed the main force of Jian Zicheng to advance along the avenue to Pigao tomorrow. He commanded his soldiers to occupy the mountains on both sides of the narrow valley.

Through the narrow valley at the bottom of the mountain, Wang Yi could even vaguely see the Zhao army on the other side of the narrow valley. He sent out the sentinels, only to meet the opposing sentries in the narrow valley, and after a brief confrontation, each retreated. Wang Yi extended his troops along the mountain beam, and from time to time met with the other party's sentinels, Wang Yu did not know the truth and did not dare to put the troops too far, he arranged the main force inside and outside the city that had been burned down, put two battalions on the mountain, and stretched out three or five miles to set up camps, and must control the commanding heights on both sides.

After dawn, the morning fog dissipated, and the Zhao army under the mountain was also vividly remembered. After passing through the narrow valley, the water made a zigzag shape, and at the turning point was naturally a mountain peak, where the observation post and command center of the Zhao army were located. The Zhao army was divided into three parts, two on both sides of the river, and the other was placed on an open field further north, apparently to prevent the Qin army from going over the mountains without going through the valley. There should be a thousand men in each of the two camps. Wang estimated that there should be a corresponding army behind the mountain, and the total strength may be 5,000 people. Although there were many troops, the camp was not strong, and no city was built. This made Wang Yi put a little snack.

Both sides made several tentative attacks, all of which were fruitless.

The valley was not wide in the first place, and it was divided into two parts for the water, which made the use of troops very difficult: not even the width of the horizontal formation. If you advance in a horizontal formation, you can only move in a column with a maximum of ten men in a row, and it may be necessary to take advantage of the width of the water surface when fighting.

The Qin army in Jianzi City walked for two days before arriving, and when all the troops arrived, it was already dark. It was the middle of winter, and the cold wind was howling. The wind passing through the valley is especially thrilling. According to the convention, the Qin army should have arrived at the battle site at this time, stayed in the enemy's city, and ate the enemy's food. But this expedition was a long way, and there were few people along the way. So on the way, ten catties of fried millet were added from Duanshi and Gaodu.

It has been seven or eight days since the departure of the party, but even if we rush through the narrow valley in front of us, it is still not a densely populated place, and we still can't find food and shelter, so we must continue to move forward.

The valley is so small that 20,000 people can't fit it at all. The so-called rule of one camp and one mile can only be ignored. The soldiers camped in shelter from the wind and lit bonfires to keep warm, and the light of the fire reflected half of the sky.

The next day, two regular battalions crossed the valley from both sides of the water. The 5,000 light soldiers followed the ridge or halfway up the hill on the south bank of the river to the other side of the mountain.

The zigzag turn of the water was to the south and then to the east, and the only open land on the south bank was occupied by two battalions of the Zhao army, behind them was the water and then the lookout and command platform of the Zhao army. This semi-encircled water covered the flanks and rear of the Zhao army on the one hand, and isolated him on the other. Wang Di's intention was to use a battalion to contain the Zhao army on the north bank of the river and make every effort to take the south bank of the river.

Two regular battalions advancing along the valley came into contact with the Zhao army: the Zhao army on both sides of the river sent a team of a hundred men to meet them in the narrow valley. Separated by a small river no less than 100 paces wide, the two teams maintained a posture of advancing in unison, so that they could take care of each other. Due to the narrow roads, it stands to reason that there is not much difference between the combat effectiveness of 100 and 500 people. But as soon as the battle was fought, the Qin army in front of them discharged a standardized hedgehog formation to stop the advance of the Zhao army; The Qin army behind jumped into the river and rushed towards the Zhao army along the riverbed, and for a while the arrows were like flying locusts, attacking the Zhao army from the side, instantly disrupting the Zhao army's position, and the team that went out to engage in the battle had to drag the wounded back and retreat, and was still shot by the Qin army in the water from time to time. The Qin army pursued together to the valley mouth, and only stopped when they encountered the camp of the Zhao army.
