Looking for ruthless OP mc in zombie apocalypse genre. No pushover mc that helps everyone. Something like who only protects his team and kill whoever provoke him. Something like: My mcv and doomsday The last human
https://www.novelupdates.com/series/my-crown-prince-consort-is-a-firecracker/ MC's very ruthless against all enemies. The TLs haven't gotten too far, but the story isn't bad.
It's a zombie apocalypse. A big bunch of the plot is her stopping it since she reincarnated from the future plus her revenge.
