[Bi-directional sexual transformation + four generations of love]
On the night when Emperor Xia Yuanrong of Dayong was poisoned by the "Woogen Evil", the water in Longyuan Pond was as red as blood.
He refused to rest in peace, and his obsession turned into a soul, traveling through four generations to find the murderer: Beijing in 1979, Nanling in the late Yong Dynasty, Paris in 2026, and aliens in 3012...
He wanted to find the murderer of the poison, but he didn't know that the concubine he suspected was also reincarnated and waiting for him at the end of time.
However, in this life, "he" became "she", and "she" became "him".
Xia Yuanrong, who had changed his gender, met his silently guarded disciple, the gloomy and brooding prince of the vassal state, the wild foreign fanatics, and the domineering interstellar commander who protected his calf.
Gender has changed, identity has changed, time and space have changed.
Only that obsession has never changed.
Who is the real murderer, and what is true love?
