It is said that outside Fengtian City, at the northwest corner, people who passed by there late at night would mysteriously disappear. The place was thoroughly eerie. A Daoist master eventually set a trap there and caught a monster that fed on human blood. Its demonic power was too strong, so the Daoist built a tower to suppress it. Afraid it might escape, he then built a Taiqing Temple opposite the tower, where generations of Daoists would cast spells to keep the monster in check. It was merely a curious folk tale, until one day during the Republic of China era, a desiccated corpse was discovered in that very spot... Meanwhile, Zhang Fengyang arrives in Fengtian City with his junior sister to seek refuge with his second uncle, only to find himself caught up in a shocking conspiracy!
