Bai Xiaoyue, the 365th generation of Xuanmen, was kicked down the mountain by her master. She was given a death order - to save her fiancé, the Prince of Jiangcheng, Pei Qingyun, whom she had never met before.
Seven days ago, Pei Qingyun was suddenly hit by the "Seven Days Evil", and his life was hanging by a thread. No one knows that behind this evil star lies a fate that was tampered with twenty years ago and a shocking conspiracy against the Pei family.
Bai Xiaoyue, who had just entered the world of mortals, used mystical magic to save Pei Qingyun's life, while being forced to team up with this "sick beauty" prince - they broke through the Ning family's coveting of the Pei family's property and the "Dragon God Technique", and were even more shocked to discover that a group of Japanese pirates were secretly planning to restart germ warfare, tear apart the country's dragon veins, and even tried to use magic to summon the Yamata no Orochi to swallow China's destiny!
The seven-day time limit is approaching, and there are families inside who are watching covetously, and there are evil spirits outside who are waiting for the opportunity. Bai Xiaoyue looked at the sharp-faced man on the hospital bed, and suddenly understood what her master said - this engagement was never about redemption, but a life-and-death situation that she, as the Tianji Girl, had to accept.
