Ling Si, learned Taoism from Maoshan to ward off evil spirits and avoid disasters. She was picked up by her master, Quexin Sanren, and raised by Wuwuju in Maonan Mountain since she was a child for more than 20 years. She was eventually rejected by her master and was driven down the mountain to earn living expenses. In real life, she and her best friend (who has some green tea attributes) fell in love with a man at the same time. Because of her status, she chose to make them happy.
Lei Kai is a policeman, but he is actually an immortal zombie. The love-hate relationship between the zombie and the Maoshan Warlock is that even though they are attracted to each other, they are always enemies.
