Although Dian Wei was a strong general, he was not a reckless general. He followed Huangfu Chaobo for several years and experienced ten battles. He was very sensitive to changes in the battlefield. When Jiang Pei ordered the soldiers to retreat, Dian Wei had noticed the reaction of the soldiers.

Seeing this, Dian Wei immediately led the soldiers of Tiebi camp to fight into the soldiers of Hedong. As a result, the soldiers who had already given up soon became more timid. In the face of the bloodbath caused by the leader of Dianwei, Hedong sergeant who was responsible for stopping Dianwei was defeated in less than a quarter of an hour.

Then, soon, in Dian Wei's relentless pursuit, the defeat of the Hedong army became a rout. With more and more officers and soldiers in the city, the defense line of Hedong army has become more and more fragile. Then, with Jiang Jian's retreat order, the resistance on the whole wall collapsed.

At this time, the follow-up army of Sizhou army had approached the wall, and soon a steady stream of soldiers boarded the wall and killed them in Hedong under the leadership of the general.

It wasn't long before the soldiers of Hedong at the head of the city were basically eliminated. Then, the east gate of Jiguan was opened. Zhao Yun, who had been ready for a long time, led Baima Yi to quickly enter the pass and controlled all parts of the pass.

And Chen Jing's Iron Eagle sharp also followed, into the pass. However, they did not ride a horse, and they passed through the pass directly, following the rout of the Hedong army. In addition to Chen Jing, Su Zhi and Yang Feng led 10000 soldiers and soldiers respectively. Their purpose was to prevent tieyingrui soldiers from going deep alone, and their way was cut off by Hedong army. Secondly, it is also to take over the city pass occupied by tieyingruishi along the way.

As Pang Tong had expected, the generals in Hedong never thought that Sizhou army would pursue him. Jiang Jian was also experienced in war, but Naihe's spirit had been lost. Although he and other generals tried hard to stabilize, they were also unable to return to heaven. In addition, Jiang Jian has led the early retreat of the barracks, which makes Jiang Jian's department even less military minded.

Fortunately, although Jiang Jian was defeated, it also blocked Huangfu's Chaobo army for nearly half a day. So when Jiang Jian led 5000 or 6000 defeated soldiers to flee, the 8000 elite led by Jiang Jian had already left for half a day.

Chiguan path is one of the eight Taihang paths. Although it is not a flying fox path, the well path is also tortuous and difficult. Fortunately, the iron Eagles under Chen Jing's command were light soldiers. Five thousand soldiers, with five days of dry food, pursued the Jiangdong army. Along the way, it was often just when the Hedong army arrived at a village and town and was preparing to have a rest, the Iron Eagle Ruishi had already appeared in the line of sight.

As a last resort, the soldiers of Hedong started to run again. Then Chen Jing left hundreds of people to defend the territory he had just captured, and continued to lead the army in pursuit. After the follow-up soldiers and horses took over, these defensive soldiers immediately went forward to catch up with the troops and horses in front. At the next place, Chen Jing left hundreds of other people behind. After this, tieyingruishi got a rest.

All the way to catch up, Chen Jing led the army to follow Hedong army to capture shaoting, Puzhang, Gucheng, Wangmao, Changzhi and Huqiu. Two days later, the army had followed Hedong army to Dongyuan County. At this time, in addition to the 8000 soldiers under Jiang Jian's command, the rest of the 30000 troops in Hedong army were left with less than 1000 soldiers.

At this time, in addition to more than a dozen soldiers who fell down because of chasing too fast, all the other soldiers were safe, and Su Zhi Yang Feng's 20000 troops also arrived at Dongyuan city half a day behind.

Seeing that the Hedong army had retreated into the fortified city, Chen Jing did not immediately attack the city, but set up a camp five miles outside the city and waited for the army to arrive. However, Chen Jing's army did not just wait. On the one hand, he arranged for soldiers to camp, and on the other hand, he made a detailed inquiry about the situation around the city. At the same time, he sent some soldiers to try to bypass the city and prepare to go around the back of the city to encircle all Hanoi's troops in Dongyuan.

There were five thousand soldiers in Dongyuan City, and there were about ten thousand soldiers in Hedong who retreated back to the city. Now there are fifteen thousand soldiers in total. However, more than a thousand soldiers who finally withdrew from the city had been frightened by the Sizhou army, so it had a great impact on the morale of the garrison in the city.

In addition, Jiang Jian and other generals did not have much confidence in guarding the city, so after gathering the generals for discussion, Jiang Jian decided to lead the army to retreat at night. Anyway, all of her people were local people in Hedong, especially the garrison in Dongyuan city were basically local soldiers who knew the terrain well. I believe the Sizhou army could not easily pursue them at night.

As Jiang Jian expected, after the night, the army retreated smoothly, and the Sizhou army did not pursue. In fact, it's not that Chen Jing didn't notice the move of the Hedong army. It's because after all, the Hakka army, coupled with several days of fierce pursuit, exhausted Chen Jing's troops. Therefore, after repeated deliberation, several generals decided to wait until dawn before marching.

Early the next morning, Yang Feng sent three thousand soldiers to take over Dongyuan County. After he was ready to take over the army, the other soldiers took Chen Jingbu as the vanguard and went along the chijing path towards Hedong.

A few days later, that is, on October 20, a total of 20000 troops of Chen Jing and Su Zhi Yang Feng finally passed through chijing and arrived at a place called LENGKOU town at the west exit of chijing. After the army arrived, they quickly attacked LENGKOU, guarded the passage of the army into Hedong, and then sent people to inquire about the information of cities in Hedong to prepare for the army's arrival in Hedong.It was not until the 25th that the Sizhou army successfully arrived at LENGKOU. LENGKOU town was a middle town under Wen Xi's rule. It was just located at the west entrance of chijing, a few miles northwest of which was Wushui. Wenxi County is located just over 50 miles down the river. However, the county is located on the North Bank of the river. Wenxi then went southeast along the Sushui River, and within 50 miles was Anyi, the county city of Hedong.

Three days later, all the troops of Huangfu Chaobo passed through the chijing and reached LENGKOU. After the army arrived, it did not send troops immediately, but took a rest here for two days. After all, at this time, the harvest of autumn crops had been basically finished. After nearly a month's March, although there was no war, the soldiers needed to rest.

On November 1, the army set out again. Along the way from Jiguan to LENGKOU, soldiers were needed to be stationed in every pass city. Therefore, at this time, the number of troops really set out was only 110000.
