Lin Yuehe and Lu Xuanyue had been engaged since childhood. Under the instruction of Princess Anyang (Lin Yuehe's mother), the two went out to travel together. As the two experienced large and small cases together, Lin Yuehe developed different feelings for Lu Xuanyue. The two were evenly matched. Suddenly, Lu Xuanyue fell into a coma during a case. When she woke up, her temperament changed drastically. She looked like him but not like him. Lin Yuehe wanted to find a flaw. She thought Lu Xuanyue was possessed by something, but later found out that was not the case. He was still him. Later, during a danger, Lin Yue Heshou was injured but insisted on going out, so Lu Xuanyue tapped her acupuncture points. It wasn't until Lin Yuehe woke up, heard that Lu Xuanyue was dead, and saw the letter he left behind and an object called a green lantern that he realized that Lu Xuanyue had come from six years later. In order to prevent Lin Yuehe from dying again, he died for her, and the green lantern left behind could help Lin Yuehe collect his remaining soul. Three years later, Lin Yuehe finally found him.
Purpose: Peace in the world
