Apocalypse: Loli Kills the World

[The end of the world + system + loli + no cp + heroine + invincible + not brainless] Let me start with the conclusion: Never mess with a depressed loli who has 99 points of mental strength. Especially when she was holding a pure black horizontal knife. My system is always trying to teach me to do things, but I want to do the opposite. It lets me kill my best friend to get gold coins. I cut my wrists with my backhand to bleed, and created a 100% immune super follower. It lets me go out and kill zombies early. I locked the explosion-proof door and waited until the zombies had been hungry for five days and could no longer walk before going to "physical salvation". The first day out... Result: one knife at a time, chopping melons and vegetables. The second zombie rushed towards me... Result: I kicked him away and split him in half. The last zombie... The result: I cut off all its limbs, turned it into a human stick and dragged it home to my best friend as a sparring partner. Zombie: "Hoo... (Are you polite?)" Best friend (collapsed and cried): "Xuexue, it's so disgusting! The ax is stuck!" Me (crossing my arms): "Pull it out and keep cutting until you can do it alone." From then on, the Holy Mother was insulated from me. The system looked at the mosaics all over the floor and fell into a long silence. [Host... Were you really a good person before? I wiped off the black blood on my face and smiled slightly: "I'm just an ordinary person who is afraid of death." Note: The system in this book is a local product of Blue Star. It has its own ideas. It is not a background board, does not use outrageous tricks, and is not a brainless text.
