[Slow Burn at First, No Zombies in the First Ten Chapters]
[Post-Apocalypse] + [System]
The Dark Age descended. Zombies roamed the streets, and countless nations were wiped out.
With the help of people with supernatural abilities, the surviving humans built thousands of massive shelters, struggling to survive the zombie hordes' attacks.
Many years later, at Shelter No. 34, Li Bing was an ordinary high school student.
He failed to awaken a supernatural ability during the awakening process, but unexpectedly awakened a System instead.
As long as he killed zombies, he could earn points, grow stronger, and make money.
From then on, a god of slaughter appeared in the shelter, a ruthless killer who massacred zombies.
"What just flew past? Was that a person?"
"A mutated zombie! The mutated zombie has been taken down!"
"The horde! Someone is harvesting the entire horde like wheat!"
(The synopsis doesn't do it justice. The story is fantastic.)
