Doomsday: I, the Reaper Walker

In 2088, global spatial rifts descend, underground cities and monsters pour into reality, and the old order collapses overnight. Chen Mo, a researcher at the Vitai Institute, is dragged into a newbie dungeon. While everyone else panics and flees, hoping for protection from security officers, he picks up the only short blade in the cave. Killing goblins, leveling up, allocating points, snatching resources—he fights his way to the top of the global system rankings. He is not a good person. He has killed those who deserved to die, slaughtered guilds that deserved to be slaughtered, and has the blood of two million people on his hands. But in the apocalypse, good people don't survive. Reaper's proxy, savior of villains. Sometimes, the ones who have to step up and be heroes are precisely the villains. — Description from novelcodex.orgFull novel: Doomsday: I, the Reaper Walker — read the rest free on N​o⁠v​e⁠l​C⁠o​d⁠e​x⁠.​o⁠r​g⁠
