Protagonist Feng Linyuan is taken to a parallel world by a system to collect entries and gain corresponding rewards and abilities, unaware that he is being dragged into a dispute among foreign aristocratic families. Three years ago, a great war broke out between the northern and southern aristocratic families, and many families fell. Entrusted to protect several eldest misses and young masters so they could live in peace in Xiangcheng, the original host soon received devastating news: the families were besieged. The eldest miss of the Chen family traveled far to the border to save her parents, only to be stopped by the original host. The original host promised to bring back her parents but lost his life in the dispute instead. The various families buried him with their own hands and paid respects every year. Three years later, the original host's physical body reappeared in the public eye, and everyone is guessing who this person, identical to the original host, really is.
