The gods of another world summoned a hundred heroes to defeat the Demon King. But something went wrong during the summoning, turning Li Wei into a demon and making him the only villain among the transmigrators.
As a vampire, he has to deal not only with the troublesome Demon King, but also with the heroes who can never die.
Fortunately, he awakened a special ability that lets him upgrade the buildings in his territory, as well as his own skills and equipment.
As the only villain among those summoned, Li Wei says he just wants to stay alive.
To that end, he decides to turn his territory into the most impregnable underground labyrinth in the world.
As for becoming the Demon King, that was completely an accident, okay?
