I Successfully Signed In Across the Stars

[Interstellar, mecha, sign-in System] Gu Xiaoqi wakes up one day to find she’s gone from the apocalypse to the stars, and a System has mysteriously appeared. The damn System won’t explain anything, just tells her to complete missions and warns her she won’t live long! System: Host, please kill one hundred mutant rats. Gu Xiaoqi: You got it! System: Host, please kill five hundred mutant rats. Gu Xiaoqi: You got it! No problem! Mutant rats: What did we ever do to you? You’re trying to wipe out our entire family!!! Just as Gu Xiaoqi is having the time of her life killing rats, some big shots show up at her door. Big Shot One: I’m your father. Gu Xiaoqi: Oh. Big Shot Two: I want you to stay away from me. We’re related by blood, and that’s all. Gu Xiaoqi: You got it. Big Shot Three: I don’t have an ugly daughter like you. Gu Xiaoqi: You called me ugly! I can’t let that slide! Just as she sharpens her knives, ready to go after the pigs and sheep (her big-shot fathers), they suddenly apologize? Hmph. You ignored me back then, but now you’re way out of my league! [This is the story of a soul transmigrated from the apocalypse, desperately trying to fulfill the original owner’s wish and stay alive.]
