In the second wave of attacks, the Zhao army sent two formations, one after the other. When the first formation was driven away from the battlefield due to the irregular formation, the second formation and the attacking Qin army were killed, and the Qin army was dispersed. But they were also unable to break through the barrier and took the initiative to retreat.

The third wave is still two formations, this time, the Qin army lying under the wall because of wearing too many winter clothes, poor heat discharge, body temperature rises, sweating a lot, there is a phenomenon of fainting and convulsions, unable to rush out, and the Qin army that rushed out is also tired and weak, and the Zhao army is about to collapse, and the Zhao army quickly approached the barrier. Beneath the rampart was a trench nearly a man high, which, although there was no water, was very difficult to pass. The halberd threw the dirt bag in his hand from behind, turned and retreated.

Wang Yi ordered that while the Zhao army was attacking, he quickly took the Qin army outside the wall back to the wall and treated them.

The Zhao army overcame the interference of the Qin army outside the wall, and the next step was to fill the trench. Wave after wave of Zhao troops came bravely, threw the dirt bag in their hands, and then withdrew. The Qin army also understood their intentions and treated each other with arrows all the way. The Zhao army started with a hundred paces and went all the way to twenty steps, and there were eighty paces away from the Qin army's arrows. Each time, quite a few people were injured and dragged back by their companions. But more than half of the trench was filled in with dirt bags again and again.

Perhaps due to the dust of the battlefield, by sunset, the sky was suddenly cloudy and an autumn rain had arrived. After the rain, the bowstrings were no longer useful due to the slackening of the bowstrings. The Qin army had no choice but to send spearmen out of the camp to block the Zhao army. The two sides fought in the rain for a while, and the rain became heavier and heavier, and even the drums could not be beaten, so both sides had to withdraw their troops.

In the following days, the autumn rain was intermittent, and there was no sunny day, the bowstring was damp all the time, and the drum was damp. Zhao Kuo continued to send small groups of Zhao troops out to fill in the earth, but the Qin army also sent troops to block it. Zhao Kuo wanted to use his strength advantage to consume the physical strength of the Qin army in a round battle, but the armies were really crowded, and it was very difficult to move the camp, which seemed to be more difficult than fighting. It seems more effective to keep the wounded soldiers out and to replenish the able-bodied soldiers from the nearby camp to maintain the combat effectiveness of the troops.

The autumn rain made Zhao Kuo worried. He was eager to know the movements of the Qin army, but since a few days ago, the spies in Hedong could not send back information, and the sentry sent to Hedong could not enter Hedong: Hedong cut off both the Yidao and Yuban Dao: the spies could only reach Yiguan from the south; If you go north, you have to make a detour to Taiyuan, and the information you get can only be the news from ten days ago.

The sudden tightening of control indicates that a major military operation is about to begin; With Bai Qi's character, being beaten passively is definitely not what he wants. Zhao Kuo was sure that Bai Qi must be plotting some plan, and he would definitely give himself a fatal blow. He didn't have the confidence to guess Bai Qi's plan,—— Lian Po couldn't do this, how could he Zhao Kuo? He could only rely on his strong troops, and gambled that he couldn't kill him with one blow. As long as he is still alive after receiving a blow, he is confident that he will definitely give Bai Qi a good look!

Since Wang Ji and Li Bing came to power, the Qin army immediately established a strict security system: the king of Qin was in Anyi, and as long as this news was revealed, countless heroes and heroes would come over like bloodthirsty jackals. In accordance with the law of Shiwu Lianzai, he strictly registered the household registration of all families in Hedong and strictly checked the foreign population; All immigrants are registered and handed over to Shiwu for detention; But those who run away will be beheaded and punished together! The fugitive is exonerated if the fugitive is reported or caught. If Shiwu thinks this person is unreliable and does not want to vouch for it, he will simply arrest him, shave his hair and beard, change into brown clothes, and go to work on the construction site! The road and Yusaka Road are only allowed to pass through those who hold special festival symbols, and other business travelers are not allowed to pass. The guards guarding the pass were led by swordsmen to serve as local soldiers, and for this purpose, the King of Qin specially mobilized a thousand swordsmen to Hedong.

The most difficult place is the Fenshang Prefecture, which is theoretically Korean land, but in fact there is no Korean army and is controlled by the Qin army; But the Qin law was not enforced there, and the main officials were all Koreans. After Pi Wan came back, he sternly warned Yang Chengjun that outsiders should never be allowed in the Korean land. Yang Chengjun naturally responded again and again, and then ignored it: I have the ability to take care of it myself, I want to take care of it, no way!

Despite leaving this backdoor, there were still problems with the intelligence transmission of Zhao's spies. The first is that the intelligence network has been disrupted or ceased to operate, and the source of the intelligence is problematic; Second, the intelligence officers themselves have to hide in Tibet, and they have no regard for supporting the search for intelligence. Therefore, when the intelligence personnel who leaked through the net finally passed the information to Zhao Kuo through Taiyuan, it was not only timeless, but also of low quality. And even if this kind of information is transmitted, it is difficult to send it consistently.

On the contrary, Chen Si's intelligence work remained effective, and the traffic between Shangdang and Hanoi was smooth. Chen Si personally sat in Yicheng, and his liaison officers jointly received the news of the Quartet informants, and then passed it on to Chen Si. Chen Si even knew that the merchants of Hanoi had a hidden path that led directly to the shops behind the mountain.

The ferocious attack of the Zhao army made Bai Qi also frown, he did not say a word, silently watched the confrontation between the two sides, thinking in his heart that he must not fight a decisive battle on the narrow battlefield like this; Meeting on a narrow road will undoubtedly give Zhao Jun a chance to risk his death. For example, in the battle in front of him, the Qin army fought very hard. If there was enough space, Qin Jun would not hesitate to stab Zhao Jun diagonally, but unfortunately not!

The heavy rain made a fool of himself. Zhao Jun should not launch a desperate attack, but he has the opportunity to build a road and attack the party. He immediately informed Sima Jin to start building the road immediately.

Sima Jin and the craftsmen surveyed the terrain a few days ago and decided on the project plan. As soon as it rains, work starts immediately. Taking advantage of the soft soil on rainy days, the roadblocks along the road were dug up and the slope was leveled. Because there is no need to ram, the amount of work is much smaller, and more than 20 miles can be leveled in a day. In just three days, the road to the Shangdang Valley was opened! Bai Qi immediately ordered all the troops who arrived at Duan, and after receiving the fried millet for that month, they immediately followed this road to Shangdang and hid in the valley.

The rain fell intermittently for five days, and all 20,000 prisoners from Guanzhong entered Shangdang. Due to the dampness of the bows and arrows, the archers all turned into spearmen.

20,000 prisoners from Shangjun were controlled in the valley behind the mountain, ready to support Shangdang and Changping. The 20,000 convicts from the Northland entered the capital and joined the convicts from the Southern County. Gaodu had a pro-battalion of Baiqi, and the public attendant of the pro-battalion temporarily commanded the 40,000 troops. After the road was built, Sima Jin returned to Gaodu with the migrant workers requisitioned from Nandu, and at the same time took over the command of Gaodu's army.

In the same five days, 20,000 Xianyang swordsmen also arrived at Anyi and completely took over the security work around Anyi.

On this day, the sky finally cleared. After the autumn rains, the weather is slightly cooler. Both sides seemed to be dissatisfied with the fact that the rain had not been able to fight these days, and as soon as the weather was clear, the various units sent out their troops. Since the bowstring is still unusable for the time being, this day is a simple impact and white-knuckle fighting.

Without the support of bows and arrows, white-knuckle combat also looked thin and weak, and although many people were injured, they were not very serious. But the loss of equipment is very serious, and the biggest loss is the shield. Under repeated impacts, many shields split into two pieces and could no longer be used.

Neither side of the war was surprised: there had never been a large number of shield shatters on the battlefield before, and the occasional individual fragmentation did not actually affect the battle. Also, how could there have been a battle for more than half a year in the past?

Zhao Kuo believed that this change would be beneficial to his side: if both sides lost their shields one to one, Zhao could eventually overwhelm the Qin army by virtue of the total number of shields. So, the next day he ordered to intensify the impact and try to smash a few more shields. He asked the rear army to concentrate all their shields in front for use in front-line combat. At the end of the day, there are always hundreds of shields that are out of action.

Zhao Kuo felt depressed, although he fought hard, he didn't seem to be able to find the weakness of the Qin army, and he could only rely on hard encounters and hard work with the other party every day. He decided to strengthen his forces in the south and try to open up the situation there. But the south was too small for the army to concentrate on. At most, two armies will be used.

Zhao Kuo thought of a way to expand the three formations of nine battalions for each sortie to four formations of twelve battalions. Frontal pressure was strengthened by increasing the number of regular soldiers of three battalions.

The Zhao army laid out twelve battalions and was immediately discovered by the Qin army, which cautiously stopped the attack and waited for the Zhao army to come.

The battle on this day was first attacked by the Zhao army. After half a day of fighting, the nine battalions of the Qin army were on par with the twelve battalions of the Zhao army. Zhao Kuo saw that the four formations could not succeed, so he once again ordered the surprise soldiers to attack. Those halberders who had received little training and had slightly weaker combat effectiveness rushed out to interfere with the Qin army's formation.

But this time, after the Zhao army's surprise soldiers were killed, drums also sounded in the Qin army camp, and another 5,000 people from the gong rode out of the camp. After resisting for two or three more battles with 5,000 men, the first one retreated. And the public attendants who lined up in formation led the army neatly pressed. Zhao Jun immediately panicked. Although the regular soldiers increased the speed of the formation, the formation was rarely tight, and it collapsed at the first touch. And those strange soldiers are even more vulnerable in front of the regular soldiers with strict formations! Their stabs were blocked by their shields, and the spears protruding from the middle of their shields knocked them over one by one. Not long after, Zhao Jun ignored the urging of the drums and ran back, and the attack turned into a big collapse.

Zhao Kuo had no choice but to send another 5,000 regular soldiers out of the city to set up a formation, and at the same time put the battle queue in front of the gatehouse, and anyone who entered the gatehouse would be beheaded. Each gate slashed several people, and finally stopped the retreat, and the routs began to form in front of the city.

The Zhao army, which hurriedly left the city, attacked first, stopped the pursuit of the Qin army, and gave the Zhao army a chance to rout the whole team. But this Zhao army was sent out temporarily, was poorly prepared, and was quickly dispersed. But the Zhao army, which had already formed a team, quickly made up for it and fought against the Qin army. With two strikes and one, he barely fought a draw with the Qin army.

Just when the battle in the south was inseparable, the defender on the northernmost Danzhu Ridge sent a military envoy to report that Qin troops appeared behind the mountain!
