Starting from the Beginning of the Zombie King, Plundering the World

Turn into a zombie and see how the protagonist turns all the worlds into his own killing ground. When the doomsday comes, opportunities come. Should he live a decadent life, or will he encounter opportunities and reach the peak of his life? The doomsday is the only time when a person can change his own destiny. In the doomsday, is it the distortion of people's faith, the loss of morals, or is it a human chessboard.
