Li Yichen, the top student in high school, has another identity: a warlock apprentice at a funeral parlor. Since half a month ago, he had been dreaming repeatedly about soldiers on ancient battlefields bathing in blood, and the terrifying golden shadow. It wasn't until his master led him into the realm of Qi training that he awakened the heaven-defying ability to swallow evil spirits and turn them into his own use. In order to protect the rare warmth of his deskmate, and to uncover the monstrous cause and effect behind the dream, he had to quietly embark on a path of cultivation leading to the eternal secret in this seemingly ordinary city. The legend of the last emperor of the human race begins from this moment.
