[Troubled Times with Alien Beasts] + [Urban High Martial Arts] + [Swallowing Bloodline] + [System] + [Dad] + [No Female Lead]
Sun Wu traveled through the world of high martial arts for thirty years. His wife gave birth to a pair of twins, a dragon and a phoenix. They died due to alien beasts attacking the city, but he awakened to devour the blood.
From then on, while devouring strange beasts and becoming stronger, he raised a pair of children on his own.
In the eyes of outsiders, he is a useless dad.
Little did they know that in just six years, he had already become the patron saint of the human race, respectfully known as the 'God of Dark Night'.
At the same time, he is also the "butcher of all beasts" that the alien beasts talk about with disgrace. Sun Wu prefers the title of "butcher".
The story of Sun Wu has undergone earth-shaking changes since the twins were six years old...
