On June 21, the fourth year of the Taiping Rejuvenation of the Kingdom, Wu Yingying led the Anxi Army and the accompanying 3,000 horsemen to camp in the south of Qigou Pass. The mountains here are steep, worthy of the name of the "sinkhole" of the governor since ancient times, and the prince of Yan Dan is using this map as bait, so that Jing Ke offers a map to stab Qin. Wu Yingying wanted to carefully observe the geography of the mountains and rivers here, so he set up a camp and dragged the 3,000 cavalry army led by Lin Zhong, becoming the only army camped in the south of Qigou Guancheng. The other forbidden troops, even when they arrived at Qigou Guancheng in the evening, must camp in the north of Guancheng to show their determination to rush desperately and protect the safety of the officials' families.

Zhang Zhongyao came to the camp with Wu Yingying after settling down with the soldiers, and saw that Wu Yingying had taken off his armor and changed into a short shirt, sweating profusely. Zhang Zhongyao Bing said: "Cui Han sent someone to pass the order, the army will cook food on the third watch, and set off on the fourth watch, and it is necessary to catch up with the palace under the command of the official family in time to defend His Majesty." Wu Yingying looked up at him, Zhang Zhongyao had always paid attention to Fengyi on weekdays, but now his face was black and yellow and full of dust, so he smiled and said: "Zhongyao has worked hard, how is the physical strength of the sergeants preserved?" Zhang Zhongyao sighed: "In the past few days, I have been traveling day and night, walking hundreds of miles every day, the sergeants are very tired, and the war horses have lost some weight. "The Anxi army originally required that after camping, it was necessary to build a wall around the camp, arrange antlers, dig trenches, and set up a fighting in the camp, but the march committee was too fast in these days, Zhang Zhongyao asked Wu Yingying, so he omitted all of these, and the most important thing for the sergeants after setting up camp was to ensure that they could sleep for two hours a day, otherwise they would not be able to fight for a long time.

Wu Yingying shook his head and sighed: "The Wu'an Western Army is accustomed to trekking, and there are a large number of horses, and even so, the other forbidden troops are even more unbearable. The imperial court urged the division to seize Yan, in order to achieve the suddenness of the attack, but with such a rapid march, once it could not quickly take Youzhou, I am afraid that it would be a situation of defeat. By the way, where is the position of the White Feather Army?" Zhang Zhongyao said: "The latest news, Yu Furen led the White Feather Army out of Shuozhou, detoured to the Shanhou Prefectures, and marched along the south bank of the Sanggan River. Wu Yingying nodded, and Zhang Zhongyao asked again: "The imperial court marches so fast, if it is defeated before the Bai Yu army arrives, we retreat west along the Sanggan River, Xitu and the Bai Yu army, or retreat south with the imperial army to this dangerous Qigou Pass?" Wu Yingying thought for a while and said: "Let's go west along the Sanggan River, the cavalry will prepare horses for foot soldiers to ride, and go west with all our might, the Liao people will track the main force of the forbidden army, and there will not be many soldiers and horses to take care of us." Zhang Zhongyao nodded yes.

The two were discussing, and the soldiers came to report that when Liu Yu, the former envoy of Qigou Pass of the Liao State, asked to see him with valuable gifts, Wu Yingying couldn't help but be surprised, and secretly said in his heart: "Could it be that the prestige of the Western Army of Wu'an has spread to the land of Youyan." ”

Zhang Zhongyao, on behalf of Wu Yingying, went out to talk with Liu Yu for a while, and when he returned, he said with a smile: "Liu Yu, who dedicated Qigou Pass, camped in Guannan with two thousand Yizhou soldiers, and waited for no one to receive and resettle, and the imperial court generals camped mostly in Guanbei. This Liu Yu saw that our department was stationed in Guannan, and he was actually sick and rushed to the doctor, and wanted to come over to see the adult. ”

Wu Yingying also smiled: "What a muddy person, he actually became a Qigou passer." It is really absurd that the imperial court allowed these two thousand surrendered troops to be stationed in front of the pass like this, neither driving them away nor reorganizing and relocating. I thought it was a messenger sent by Han Derang to contact, but who knew that it was such a headless fly, Wu Yingying's heart was suddenly relaxed, he flipped through the gift list submitted by Liu Yu, there were fifty taels of gold, five hundred taels of silver, twenty night pearls, and ten tiger skins, Wu Yingying smiled again: "This Qigou Guan envoy is really a fat shortage." Since they have given gifts, I will see him. ”

Zhang Zhongyao brought Liu Yu forward, and Wu Yingying arched his hand with him: "General Liu, please take a seat." After Liu Yu sat down, he took a sip of tea and sighed: "Since the dedication of Nantou, Yu Wangmen has stopped, and he has to see a person who sits, only here in Wu Jiedu." He asked to see Pan Mei, Cao Han, and even the generals of the forbidden army such as the military commanders below, either they didn't have the opportunity to meet at all, or they just said a few words lightly after receiving the gift, which was completely insignificant. Gradually, there are rumors that Yan Yun's surrender to Cheng's generals will be demoted to the south to serve, and they are not allowed to bring their subordinates, Liu Yu can't sit still now, he has to be the envoy of Qigou Pass as a Han person, and he has his own merits, although his heart is to the south of the dynasty, but he is not willing to be so obscure and idle, so he made a heart, and heard that there is a festival to make the big man stationed in Guannan, so he prepared a heavy gift to ask for a meeting, not for himself, what to say is to seek a good background for the two thousand Yizhou children.

Wu Yingying couldn't help but smile dumbly when he heard his intention, and said: "General Liu can know that my Anxi Jiedu envoy is not a false title, and the subordinate garrison is the northwest border villages such as the former Tang Shuofang, Hexi, and Anxi, and the imperial court forbidden army, which is not a system. He bit the word "system" very hard, Liu Yu is not a fool, naturally understood the meaning of his words, and couldn't help but hesitate, Wu Yingying saw that he was embarrassed, so he smiled and said: "It's okay, Yizhou Jian'er is sharp, although the court is eager to enter Youzhou and has no time to pay attention to it, when the war is understood, there should be a place to borrow General Liu, I am here to replace wine with tea, and I will respect the general first." After speaking, he picked up the teacup, Liu Yu drank the tea with a sad face, and got up to say goodbye.

When he was about to leave the camp, Zhang Zhongyao chased him out of it and said with a smile: "My family is useless, the general is the one who leads the troops, and there are still many places to use the money in the future, so take back these gifts." Liu Yu was quite embarrassed, and before he could refuse, Zhang Zhongyao ordered the Yajun to return the gift to Liu Yu's subordinates and turned to leave. On the way back, the clerk Qian Qing suddenly woke up and said: "This Anxi Festival makes Lord Wu, isn't it the Northern Han Tuhun Army Festival Envoy Wu Hero who risked his life to redeem tens of thousands of Han households?" Suddenly, he muttered: "Qian Qing, the left and right are soldiers to eat food, if I lead the army to Anxi, will the brothers agree?" Qian Qing saw that he suddenly asked, did not dare to answer rashly, after a period of silence, Liu Yu sighed, urging the horse forward, at this time in the dead of night, the sky is covered by black clouds and the moon, and the road in front is pitch black, which is similar to his mood at this time.
