Under the cover of shields, the Qin army pressed towards the Zhao army step by step, and extended its wings to both sides, extending into the mountains and rivers. At the same time, the second echelon of the Qin army also entered the valley and came with reinforcements. While stabilizing their own camp, the Zhao army drew troops from another battalion to harass the flank of the Qin army. The Qin army relied on the higher terrain and tried its best to maintain it.

When the two battalions of the Zhao army concentrated on attacking one battalion of the Qin army, the Qin army appeared all over the mountains on the top of the southern mountain, they held halberds in their hands, did not form a rank, and rushed down from the mountain with a shout.

In the mountains, the weakness of the phalanx's bulkiness is exposed, while the nimble skirmishers are able to exert a high level of agency. In particular, the Qin army sent as many as 5,000 strange soldiers, five times that of the Zhao army, and no matter how brave the battle was, it could not offset the numerical disadvantage. First, the Zhao army, which went up the mountain to attack the flank of the Qin army, was defeated, and then the Zhao army's formation, which confronted the Qin army's formation, was involved. After a period of resistance on the back of the barracks, the two battalions of the Zhao army on the south bank of the river were completely routed. Due to the relatively independent terrain on the south bank of the river, it was difficult for the reinforcements in the rear to cross the river, while the troops on the north bank were pinned down by the Qin army and could not move at all.

After defeating the Zhao army on the south bank of the river, the Qin army immediately followed the defeated army across the river. This side of the river is the command post of the Zhao army, 5,000 stragglers rushed up the mountain, there was indeed a reserve of 2,000 people behind the mountain, but 1,000 of them had been ordered to prepare to cross the river to reinforce the troops on the south bank of the river (but they didn't have time), and they were in motion, and the other team hurriedly climbed up the mountain, and before they could get in formation, they were surrounded by stragglers. After a rain of arrows, more than half of the Zhao troops on the hill were killed and wounded.

The battalion bought time for Lian Po to retreat down the hill and command the remnants of the troops on the north bank of the river to retreat in turn. Since the main force had not yet come up, and his assault group had suffered heavy losses, he did not pursue excessively, and only let a battalion be three or five miles away from the Zhao army, thinking that it was a warning; The rest of the divisions occupied defensive positions, firmly controlled the valley mouth, and covered the passage of large forces.

Out of the narrow valley mouth, there is a flare-shaped slope, and after the downhill is a large pastoral field, dotted with countless streams and lakes. Wang Di's heart was relieved, and he finally broke out.

Since he had never been to this place before, Wang Yu could not determine the deployment of the various units, so a battalion came over and asked them to occupy the nearby Yili and strengthen the vigilance. By the evening, thirty battalions had finally been arranged.

Immediately after the defeat of the Zhao army at Pigao, they retreated northward along the river, retreating for about thirty miles, crossing a river and entering a city. The Qin army that was tracking saw that this place was heavily guarded and did not dare to get too close, so they sent someone to report to Wang Di. Wang Di came over, and sure enough, he saw that there was a perfect defensive position along the river with the city as the center. Wang Ji had no choice but to withdraw the camp to ten miles and set up camp in a settlement.

The stragglers of the first ten battalions of assault rested in the camp left behind by the Zhao army, covering the wounded. In order to quickly break through the valley pass, this army rushed very fiercely, suffered heavy losses, almost a thousand people were wounded, and two or three hundred were seriously wounded. Wang Ji planned to let the 1,000 people return to the party tomorrow.

The next day, the whole army assembled, Wang Yi redesignated the defensive areas of each battalion, and led the front army to continue to advance. Due to the relatively flat fields and the proximity to the Zhao army's city, the front army led by Wang Yi consisted of a phalanx of 5,000 men. After advancing for more than ten miles, I saw that in many towns in front of me, the Zhao army withdrew one after another. Wang urged his troops to speed up, tracking the retreating Zhao army to the bottom of the city.

The scale of the city in front of me is not small, it is three miles square, tall and strong. A small stream flows through the south of the city, pouring into the water not far away. There is a camp outside the city, which echoes the city. Ten miles away, there was a tall city, similar in size to the one in front of him, and there was a camp outside the city.

Wang Di divided several battalions to clean up the settlements left by the Zhao army and occupy them. Strangle your own troops on the main road. At the same time, military envoys were sent to let the battalions requisition labor to build fortifications!

Building a fortress under Zhao Jun's nose was a very risky move. Moreover, the distance that Wang Yu asked to build the fortress was only a hundred steps away from the river, and it was only a mile away from the opponent's camp, which was equivalent to building the camp to the opponent's face.

Wang Ji controlled 5,000 elite troops by the river and personally covered the fortification. A large number of Yi people, driven by the soldiers of the Qin army, arrived with farm tools, and began to dig a trench at the foot of Wang Ji and them, and the excavated soil was piled on the edge of the ditch, and the other people rammed it layer by layer into a camp wall. There were a lot of people from all over the city, and the Zhao army did not come out to interfere, and the fortification work was completed very smoothly, and in just one hour, the camp about a thousand steps long between the two towns was built. Wang then transferred his forces and went to the next area to build a fortress.

For a whole day, under the supervision of Zhao Jun, the Qin army completed the construction of the entire area, and the total length of the barrier reached more than ten miles. These barriers are intermittent, defending only the weakest link, and if the Zhao army wants to attack, it can always infiltrate, but at some cost. Wang Yi was very satisfied with today's results, and he sent the people back to rest and continue tomorrow. After arranging the remaining troops, Wang Yi led the elite corps to live in several Yili arranged by the five doctors of the guard. One day was enough time for them to familiarize themselves with the area and arrange their troops.

So, in the tacit understanding between the two sides, Qin and Zhao confronted each other on this land. The Zhao army was content to confine the Qin army to a harmless area away from Handan, while the Qin army was content to have a place to spend the winter and eat, instead of sleeping in the open and eating fried millet in the middle of winter.

Both Wang and Lian Po reported to their respective capitals on the movements of the battlefield. Wang Yi's report was that the Qin army had occupied Wu'an Pigao. Lian Po's report was that the Qin army had been stopped under the city of the Five Clans.

As time passed, memories of the past gradually returned to Wang's mind. He remembered that this was the place where he had followed Hu Yang ten years earlier, but the difference was that at that time, their position was on the north side of this defensive line, roughly the same as the Zhao army's defensive line.

After reconnaissance, the Zhao army was about 10,000 people, roughly the same as the Qin army, but it was backed by two strong cities and close to Handan, so it could be reinforced at any time. And he is far away from the rear, even if Shangdang is three or five hundred miles away, and Shangdang is an empty city, in vain.

After a few days of inspections, Wang also had a general idea of where he was: in a triangular area formed by the flow of water from the southeast to the northeast. To the south is a half-high hill where Lian Po's command post used to be located. Turning over this mountainous area, there is a large gathering on the other side of the mountain, and there is not much food, mainly iron smelting! This made Wang Yi very excited.

Since the last time he followed Hu Yang to Wu'an, he witnessed a large number of iron-smelting workshops in Wu'an, and Wang Yi had the idea that it would be great if he could have inexhaustible iron farming tools! This time the fortification went very smoothly, in addition to the fact that the Zhao army did not come out to interfere, the iron farming tools owned by the people of Yi were also an important aspect. If you use a wooden rake, you need to water the ground first, and then dig it, which is time-consuming and laborious. It's different with a shovel, dig straight down, and the soil will be cut out like tofu!

He had a public attendant who was in charge of making and transporting iron, and told them that they could exchange it for salt!

A few days later, the bus passenger reported that he had inquired about the commercial route from here to Shangdang, which had been very busy in the past, but had been cut off for several years due to the war. Wang Yi immediately asked him to resume this trade route, and reported it to Xianyang, and at the same time informed Wang Ling and Pi Juan. So every few days, there was a car that went up the river to send the iron tools to Licheng; Wang Ling sent people to trade salt in Licheng, and then each returned.

On the road from Handan to Luoyang, the messengers came and went, and on the road from Luoyang to Xianyang, you can see the riders galloping from time to time. Wang Di's report passed through Shangdang and Hedong day by day, and was reported to Xianyang, and Pi Wandu led 10,000 prisoners to repair the roads from Anyi to Shangdang, Anyi to Yuancheng, and between Shangdang counties. Wang Ling led 10,000 soldiers to renovate the countryside and houses in the eldest son, Tunliu, Lucheng and Xiangyuan, reorganized according to the Qin system, dug ditches, and burned wasteland. The Shangdang, which had been cut off from the crowd, regained its vitality.

In the cities of Tongyun, Nishi, Licheng and Shaoshui, Wang Ling sent soldiers to collect taxes from them. Unlike the Qin State that celebrated the New Year in October, these places still celebrate the New Year in the first month; Since the Qin law had not yet been implemented in the royal tombs, the inhabitants of these cities were hardly aware of the change of regime, and still paid the taxes of that year as was customary in previous years.

Although there are more than a dozen cities that pay taxes, these cities have a small population, little arable land, and not much grain paid, which is about enough for 20,000 people to eat for half a year. Pi Wan on the one hand to build the road, on the other hand to send people to transport salt, salt is higher than the value of grain, a stone of salt can generally be exchanged for three stones of more grain, in the east of the river to salt for grain strategy, one stone of salt can also be exchanged for two stone of grain. Wang Ling ordered people to buy salt and grain from various cities, bought and sold fairly, and also purchased a lot of grain. Hedong sent another seed, and sowing will not be a problem this spring.

After several bargains, Zhao Hao finally completed the peace negotiation, Zhao offered six cities, and Qin withdrew his troops. It's just that the six cities offered are not the six inconsequential cities proposed by Su Li, but the cities located in Taiyuan and Wu'an. The Qin State wanted to use the peace treaty to fix the results of the war. As part of the peace treaty, the King of Qin sent a prince to Handan as a hostage, while the State of Zhao sent Pingyuan Jun to Xianyang to meet the alliance!

Since the king of Qin only had one son of the crown prince, it was decided that the son of the crown prince, Gongzi Yiren, would enter Handan as a hostage. In mid-December, Childe Yiren set out on the road to Handan......
