The play is adapted from Ma Boyong's novel "Luoyang", which tells a series of stories about a group of people from different classes during the Wu Zhou period who investigated the unsolved case in Luoyang. Gao Bingzhu (Huang Xuan), a bad deputy commander from the bottom of Luoyang, was involved in the case by mistake and became a suspect. While trying to prove his innocence, he met Baili Hongyi (Wang Yibo) who was trying to find out the truth about his father's poisoning. The two cooperated and started an investigation. Siyue (Song Qian), an inner guard from a noble family, investigated and approached Gao Bingzhu, who had superb martial arts and quite a bit of street wisdom, for a mission. He wanted to find a letter of denunciation related to the case. The two people from completely different classes disliked each other, but had to be tied together. As they continued to delve into the case and find the truth, they discovered a shocking conspiracy that could destroy the capital of gods and stain Luoshui with blood.
