I Upgraded Like Crazy at the End of the World

When the doomsday comes, one person and one knife can kill through the doomsday. The ground was covered with bloody corpses. In the wilderness, strange beasts run rampant, and the royal city holds a blade and is bathed in endless blood. Enter the city and step into the wilderness. In the land of blood sea, build a new world from scratch. An authentic doomsday novel, if you don't like it, don't criticize it. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
