Snake demon chasing the soul

Starring:,, Tang, Lin Sihui (played) is actually the reincarnation of a snake girl who died unexpectedly before her father was born. After she was born, she cried for several days, so she asked the old mage to tell her fortune, pointing out that she was reborn as a snake girl in her previous life and would be a coward in the future. Unfortunately, she could not raise shit, so she was given to the snake prince to live a peaceful life. Ten years later, Lin Sihui killed several men in succession, and finally talked about marriage with Qingshi, a man from another village. When they got married, Zhao Tianbao got in the way and forced Qingshi to jump off the cliff. When Lin Sihui was about to be raped, the snake king appeared, but Zhao Tianbao also took off the cliff. A few years later, Lin Sihui came to Hong Kong, worked in a massage parlor, and met the playboy Charlie (played by Cao Chali) who was originally among women. Charlie was moved by her beauty and gentleness and fell in love with her even more. Despite all the difficulties, they finally decided to be together. At this time, Lisa, the daughter of the boss in Charlie's company, came back from abroad, and the company asked Charlie to accompany her to travel. Lisa showed kindness to Charlie, but Charlie refused to be angry. Later, she fired Charlie even more angrily. In order to make a living, Charlie found a new job. The task is to receive Michiko Tanaka, the wife of the Japanese boss. Accompanied by Charlie, Charlie's careful care made Michiko's lonely heart feel a little warm after years of widowhood. Later, Charlie met his friend Peter's aunt, who is a ghost hunter. Seeing that Charlie's noodle restaurant was dark, she gave him a string of beads to keep him safe and let him take them with him in the morning and evening, but Charlie was afraid of a conflict with the snake king and didn't take it to heart at all. Michiko wanted to be alone with Charlie on his last night in Hongkong, but he was turned down. At this time, Zhao Tianbao, a dead bully, made an issue of Michiko. Lin Sihui, who was worried about Charlie's accident, went out to find Charlie, but was stopped by Zhao Tianbao on the way to catch Sihui. At this moment, Charlie, who just came back from waking up, got into a fight with Zhao Tianbao. In the battle between man and ghost, Charlie lost his life even more. Charlie, who turned into a ghost, used the beads given to him by his aunt to fight against the evil ghost Zhao Tianbao. Eventually, Zhao Tianbao's soul was scattered, but Charlie himself lost his life, leaving a sad and tearful thought.
