Sister, can I be the scabbard too?

[Abstract][Fun][Multiple Heroines][All Gods] Lin Yuan's system malfunctioned. [You have successfully tamed the time-traveling hound, which can be transformed into the divine artifact, the Sky-Waving Cloak, at any time, and used for instant teleportation.] Lin Yuan looked at the Border Collie wagging its tail at him, lost in thought. [Your wisdom is unparalleled; you have successfully completed the test left by an ancient powerful being, learning the skill Time Stop.] Lin Yuan looked at the advanced mathematics exam paper in his hand, his lips twitching. [You descended from the heavens, furious and ferocious, suppressing the world-destroying witch Tang Feixue with one hand, and can transform her into a god-killing weapon.] Lin Yuan looked at the silver-haired girl Tang Feixue, who tripped over her own feet and fell flat on her face in front of him: "Her? Tang Feixue? World-destroying witch?" [Oh no, the system malfunctioned.] "Phew... I knew it..." [The suppression is not yet complete. To purify the witch's corruption, you must call her 'Mom'!] "?" ...My name is Tang Ling'er, Tang Feixue's younger sister, a reborn person. Seven days from now, a post-apocalyptic game will invade reality. In my previous life, I fought with everything, yet still met a tragic end. Only before I died did I learn that my sister, Tang Feixue, had become the sword of the top player, Lin Yuan, living a princess-like life. Reborn, I must find Lin Yuan and sign a contract with him before my sister. He possesses the power to transform all beings into extraordinary beings; he is the sole king in this apocalypse. Ah, my foolish sister, I'm sorry, the struggle for the throne is always like this! Hmm? Wait a minute? How did I become Lord Lin Yuan's sword sheath?!
