I Am Ajiu!

Twenty-five years after the apocalypse, alien species are rampant outside the wall, alien beasts are in power, humanity within the wall has been wiped out, and order has been restored. There is a world outside the walls, and a world inside the walls. Before Ah Jiu died, he didn't hate anyone, he only hated the world! Why are you weak if you don't have superpowers! Why must we be abandoned if we don't have superpowers! Return again and use your flesh and blood to become the God of War!
