When Ying Xue and Zheng Dai returned to Tianguan, it was already midnight. After discussing for a while, they immediately went to Lai Rong's camp according to the secret password agreed by Lai Rong. Lai Rong's messenger saw Zheng Rong and knew that the matter was urgent, so he immediately informed Lai Rong. After Lai Rong heard the news, he saw that it was Lai Rong who came in person, so he had to get up and meet Zheng Rong. "General, it's really urgent. I have to come in the middle of the night to bother you. Please forgive me. If you don't help us this time, then our plan to surrender will be in vain." There was a burst of tension in the heart of Zheng Dairong's words. He still didn't know what had happened. Seeing how serious Zheng Dai was, he knew that something unusual was going on.
