[Ruthless protagonist] [No female lead] [Fast-paced]
I transmigrated into the weakest disciple of the Demon Sect, someone everyone could kick around.
Luckily, I have a System: the Great Blood-Sucking Demonic Art.
But the System says I’ll die if I go seven days without drinking blood.
I suck blood from fellow disciples, demon beasts, and even the sect master.
I suck my way onto the wanted list of the six great righteous sects.
The sect master says, “Suck as much as you want. If that’s not enough, I’ll send you my disciples too.”
Later, I sucked the sect master dry as well.
They think I’m a fiend, but I just want to survive.
And get stronger while I’m at it, and wipe out a few sects along the way.
Actually, never mind “along the way.”
I am the fiend.
