Xiao Mu, whose real name is Xi Mu. He is an elf who is impatient, stupid at selling, lazy at eating, and doesn't like to be clean. After staying in the human world for nearly ten years, his mission was to develop a drug called chlorophyll that would stop vampires from sucking blood. In order to avoid unnecessary trouble, spiritual power is sealed when there is no threat.
Su Lan is a dark vampire who likes to pretend to be pigs and eat tigers. After sleeping for nearly a hundred years and about to wake up, he was locked up and exiled to the human world as an infant. He was called to experience life.
"Xiao Mu, can you not be so stupid that you always leave opportunities for me to complain?"
"..."
"Honestly, why are you doing experiments all day? Otherwise I will strip you naked~"
"You are really wordy... Uh... Hmm~"
