Su Wanzhao, a folk spiritual husband, was selected into the Daqi Palace and made a nobleman for cultivating the "Blood Moon Orchid" that can restrain vampires from healing themselves. On the night I entered the palace, I witnessed the horrifying scene of the noble concubine Murong Xue sucking the blood of the palace maid, and then I discovered that there was a vampire group called the "Blood Shadow Clan" hidden deep in the palace that feeds on the royal blood and plots to usurp the throne. I became a thorn in the side of the Blood Shadow Clan because of the "Blood Moon Orchid", and was also used by the emperor as a pawn against the Blood Shadow Clan. In order to survive, I had to get involved in the harem battle: deal with the queen's suppression, the noble concubine's frame-up, and the other concubines' schemes, while hiding the secret of the "Blood Moon Orchid"; using the emperor's favor to gain power, and be wary of his suspicion; joining forces with Xiao Jingheng, the Sixth Prince of the Lonely Star of Heaven and Earth (who can sense the breath of vampires), to investigate the Blood Shadow Clan's lair. During the process, I discovered that I was a princess of the Blood Shadow Clan (my master sealed my bloodline to protect me). Faced with the choice between family ties and justice, I chose to stand on the side of humans, destroy the Blood Shadow Clan's lair, become a queen, and protect the peace of the country.
