[Fell in love and killed each other + real male ghost + two evil people]
"Under Hengmen, you can live in Chi"
Qichi here should refer to habitat. Unexpectedly, Zhong Qichi really became a ghost lingering in the world and refusing to leave.
At his funeral, Shen Zhaowang, who had disliked him since he was a child, was not happy. Others thought he was sad because his son was gone.
Little did he know that he only regretted it because someone else killed Zhong Qichi first.
On Shen Zhaowang's way home, perhaps because of his overly rich imagination, one person and one ghost were surprised to find that Shen Zhaowang was the only person in the world who could see Zhong Qichi.
The two reached a cooperation and prepared to find out who killed Zhong Qichi.
