Zombie Apocalypse: At the Break of Dawn

A zombie crisis breaks out across the world! Humanity builds a 50-meter-high wall!

People are divided into ranks S, A, B, C, D, and E!

S-rank people are humans who have taken enhancement serums and possess great strength! Their strength and speed are enhanced! They are hailed as human weapons, killing machines for clearing out zombies.

The ranks gradually weaken from S to E. E-rankers are ordinary people who have never taken an enhancement serum!

The protagonist, Yi Xiaole, is an E-rank human surviving behind the human wall. He receives the least food and is assigned a place to live beside the latrines. Scraping by, he endures day after day of being looked down on. But one day, a special zombie breaks through the wall, and everything changes...
