[Pseudo system + multi-racial arena competition + fragmented world + multiple female protagonists]
Tang Muzhi is an unlucky child
As soon as he traveled through time, he was dragged into the arena by the devil, and the blood of succubi and vampires was stuffed into his body.
He ran to the human world, only to be sent to a research institute.
In the end, Tang Muzhi discovered that monsters are much simpler than humans and demons, and vixens are really good-looking—ahem!
In order to help his demon clan avoid being homeless, he decided to help the demon clan rise among many forces and become bigger and stronger! Create greater glory! !
