A Knife from the Start: I Slaughter My Way Through the Apocalypse

[Reborn + System + no female lead + no naive saintliness + decisive and ruthless + zombies] The apocalypse arrives, and Long Yi is reborn on the very day it begins. After struggling to survive for five years in the wasteland, only to die because of deception and betrayal, he vows to kill every one of his enemies with his own hands. When the apocalypse comes again, he bonds with an Optimization System, maxes out his drop rates, and gets his revenge one step at a time. Survivors: “A horde of zombies is coming! Run!” Long Yi’s eyes light up as he draws his long blade and charges at the zombies. “Don’t run, experience points!” Survivors: “This boss is too tough! Retreat!” Long Yi charges at the boss coming straight for him, blade in hand. “That boss’s golden chest is too good to pass up.” Survivors: “Whoa! We found some expired bread and milk!” Long Yi: “Let’s have a simple hot pot today.” With that, he pulls out a giant lobster and bluefin tuna, rinses his mouth with red wine, then takes a swig of soda. He lets out a blissful hum. Survivors: “How does this guy have so much delicious food?” Long Yi: “I earned it one slash at a time. Got a problem? Go do the same!” Long Yi says: “Just give me a weapon, and I can cut down the whole world.”
