At this time, the martial arts factions heard that Youzhou was in trouble and came to help one after another, and Lian Guozheng said gratefully: "This time Youzhou is in trouble, thank you martial arts heroes for coming to fight with our army." The people of all factions saluted and said: "General Lian doesn't have to be polite, your fourth brother Lian Guoyuan and Mrs. Lian are our friends, and their brother is in trouble, how can we sit idly by, not to mention that this is to protect our Han people's country." "Yes, the scouts reported back: The Khitan soldiers have set up camp not far from the city. Lian Guozheng hurriedly led the crowd to climb the city tower to watch, only to see the dust in the distance, a brave and huge Khitan army slowly arrived, the Khitan leader Li Quanzhong sat in the army with a menacing look, followed by some strangely dressed martial arts people, and the missing General Yun also suddenly appeared in the Khitan army. Lian Guozheng couldn't help but exclaim in surprise when he saw it: "Brother Yun." Everyone looked at each other when they heard this, and someone said: "It turns out that the rumors are true, General Yun has really surrendered to the enemy." Lian Xiao said: "Uncle, I see that Uncle Yun's expression is abnormal, there must be something hidden in it, it is better to let the child explore the Khitan camp at night to see what is going on." Lian Guozheng acquiesced.

At night, at the second watch, Lian Xiaochong flew down to the city dressed in black and infiltrated the Khitan camp alone. The Khitan king Li Quanzhong was plotting with the generals in the tent, and the Khitan king ordered the Khitan warriors to bring General Yun into the tent, and two officers and soldiers entered the tent with the sound of the order. The Khitan King said: "General Yun, now all the Tang people think that you have betrayed the enemy, it is better to surrender as soon as possible." Yun said with a serious face: "If you want to kill, you have to scrape, you don't have to waste your lips and tongues." The Khitan king said: "General Yun doesn't have to be anxious, this king still wants to take you to Youzhou City to have a look." Yun Dao: "My Tang Dynasty is full of talents, all brave and good at fighting, is it a place where you want to go wild." The Khitan general Halu sneered: "If you go back a few decades, you say this, I still think about it, now it's a fart, you can't even figure out whether the surname Li or the surname Wu is now, your so-called brave general has already been killed by your female emperor, I'm afraid there will be no more incompetent people." He laughed out loud. Yun Dao: "My Tang Dynasty has many talents, how can you understand it." The Khitan king said: "There is no need to argue, it will be clear on the battlefield." So he ordered General Yun to be taken out of the good life guard. Lian Xiaochong secretly followed to General Guan Yun's camp. Due to the special orders of the Khitan king, the guards were very strict, Lian Xiaochong tried to sneak in but failed, seeing that the sky was getting brighter, Lian Xiaochong had to give up and return to the city.
