After leaving the prefect's residence, Zhao Yu immediately rushed to the cavalry camp outside the city, because he didn't know how the current war situation in Chifeng City was. Zhao Yu decided not to wait for the troops of Luanping and Shuangluan cities, but directly led the two thousand cavalry of Chengde down to Bancheng. After meeting the five thousand troops of Xiabancheng, he immediately set out to Pingquan city.

In Meng Yi's plan, Pingquan is the last line of defense, while Xiaosigou town in the north is the first line of defense. Therefore, Zhao Yu decided to rush to Pingquan city as soon as possible. If he arrived one day earlier, he could make preparations one day earlier.

The two thousand cavalry left Chengde and headed for Xiabancheng in the East, just like the flood that burst the dike. The soldiers and horses of the other two cities would arrive at Pingquan by themselves and join Zhao Yu. As for the follow-up food, grass and supplies of the army, it was Yuan Si's business.

More than an hour later, more than 2000 cavalry arrived at Xiabancheng. At this time, there were 4000 soldiers and 1000 cavalry waiting outside the city. The leader was Hao Jian, the master of Xiabancheng.

After meeting five thousand soldiers and horses in Xiabancheng, Zhao Yu only ordered a short rest, and then led three thousand cavalry to set out first. Hao Jian also followed her out first, and four thousand soldiers were handed over to the deputy general.

Three thousand cavalry trotted all the way and finally arrived at the foot of Pingquan city before dark. At this time, the officials and generals in Pingquan city had become frightened birds. They closed the two gates of Pingquan city one hour before dark.

There is no way. The letter of help from Chifeng City was sent to Chengde from Pingquan. There are only a thousand soldiers in Pingquan city. Fortunately, Pingquan city is not big, and there are only two gates in the north and south. A thousand soldiers can basically fill the city. If Xianbei people attack, a thousand people will not be enough for others.

When the rumbling horse hooves sounded in the south of Pingquan, the defenders in the city were in doubt. They immediately sent someone to inform the county magistrate and county Wei who were on the north wall.

When the county magistrates hurried to the Nancheng tower, 3000 cavalry also arrived at the foot of the city. They stopped 200 steps away from the city wall. One of Zhao Yu's guard cavalry stepped out of the crowd, walked 100 steps away from the city wall and shouted to the city head, "who is on duty in the city? Zhao Yu, the governor of Yanbei county and guerrilla general, led his department to help. The principal officials in the city please come out and answer!"

In fact, at this time, the people in the city have basically determined that the cavalry under the city is their own reinforcements, but for the sake of safety, the county captain still stretched out his head and shouted to the outside of the city at the sign of the county magistrate: "Pingquan County respects here, general under the city, please show your seal!"

Zhao Yu listened to the shouting above the city wall and nodded gently. Yes, it seems that the county magistrate and county captain are sober and know to confirm their identity first. Thinking in his heart, his right hand took out his seal from his body and handed it to another guard. He came forward, put the seal in the hanging basket put down at the head of the city, and pulled it up to the officials at the head of the city for verification.

Soon, after careful checking, the people at the head of the city immediately ordered to open the gate and welcome Zhao Yu and his cavalry into the city.

Under the guidance of 50 Huben cavalry, Zhao Yu and his party of more than 3000 cavalry soon came to the gate of the city. At this time, the county magistrate and the county captain had come down from the head of the city and stood at the gate to meet Zhao Yu.

"Lower officials welcome Zhao guerrilla!"

"Don't be polite. Please arrange a resting place for the army. From now on, I will take over the defense in the city. Now can there be new news from Chifeng City in the north? Can the sentry post of Xianbei people appear?" Zhao Yu didn't do more polite with a group of officials, but asked directly;

"When a general comes, we can rest assured. If we return to the general, there is no news from Chifeng after the first rescue letter from the governor of the king. Because of the lack of troops, the lower officials have not sent troops to Chifeng to inquire about intelligence."

"I would like to ask the general, how many troops and horses will the king send to support? Is it the 3000 cavalry under the general's command?" The county captain asked anxiously;

"You can rest assured that these 3000 cavalry are just forwards, and there are more than 10000 infantry and thousands of cavalry coming later." Zhao Yu glanced at the county captain, then turned to Hao Jian: "general Hao, please send an inspection post North immediately after settling down the army. You must find out the current situation of Chifeng City."

"No command!" Hao Jian hurried forward to take orders, then turned around and led 3000 cavalry to the camp in Beicheng under the leadership of the county captain.

After the 3000 cavalry left, Zhao Yu was left with only 100 Huben cavalry guards. According to the will of Huangfu Chaobo, the guards of generals at all levels are required to have a certain amount. For camp leaders like Huang Xu, the number of guards is 50. For example, Zhao Yu's post is county lieutenant, and there are 50 personal guards in wartime. However, Huangfu Chaobo takes special care of her and Huang wudie, and arranges 100 Huben cavalry guards for them to protect their safety.

While walking towards the county government office in the city, Zhao Yu kept asking about all kinds of situations in the city. Fortunately, although the county magistrate arranged by Gongsun Zan is not a talented historical general, he is also very conscientious. In addition, Pingquan has only been built for several years, so he is familiar with the situation in the city and can quickly answer Zhao Yu's questions.

After Zhao Yu asked some questions, he basically knew the situation in the city: "so, please prepare to recruit people. After the news came back from the detective post, I would have arranged to strengthen the defense of Xiaosigou town. If possible, I would have wanted to build Xiaosigou town into a pass as the most important pass to resist the southern invasion of Xianbei."

"From now on, I will be responsible for the defense of Lulong cities. You just need to obey the order. The county magistrate, from tomorrow, will gather all the young men and craftsmen in the city and follow me north to Xiaosigou town. If I remember correctly, there should be enough to build a medium-sized pass in Xiaosigou town."

"See you, general!" The county Lieutenant replied, "Xiaosigou town is built at the two estuaries where the tributary of Laoha river meets. The location is still very good, but if a pass is built in Xiaosigou, it is a little worse. Therefore, it is not suggested that if the general wants to build a pass in the north of Pingquan, he should continue to go south along Laoha river. The location between Nanshan and Ma'anshan is the best."

"Oh, the county lieutenant is very familiar with the terrain here?" Zhao Yu listened, his eyes lit up and asked;

"To be honest with the general, after taking office for a few years, I almost walked through the large and small Goulong in Pingquan. Although I don't know the terrain in Pingquan, I still remember it by heart." The county captain said proudly;

"Well, tell Ben about the terrain there." After that, Zhao Yanjun was put on the map.
