One night, when Jiang Liu'er and Pan Guoxing were studying the game in the kitchen, Lei Lingyun, who was hiding outside the door, finally knew the truth. The day of the duel between the brothers and sisters came, and Pan Guoxing told Xiao Yanzi with confidence that he would defeat Lei Lingyun and marry her. And Lei Lingyun smiled. When everyone came to the chess building and Lei Lingyun and Pan Guoxing were about to compete, Lei Lingyun asked his juniors to arrest Jiang Liu'er. Just when everyone was surprised, Lei Lingyun told Guo Fengchun that he had caught the murderer of the old national player Liu Runan for his master.
