Ever since, the two races have lived in their separate worlds, until now.

During the deadly pursuit, the dim-witted Tianyin is caught up in the middle. In order to save her heir, the dying monster queen spills her egg into Tianyin’s mouth, making him the bearer of the future monster king. Now the most wanted man, Tianyin and the newborn monster’s lives are at stake. Miraculously, rookie monster hunter Xiaonan saves the day. She offers to protect Tianyin under the condition that they sell the newborn monster for a good profit. Do they have what it takes to confront the danger ahead?
