Quick Transmigration: Leng Yue’s Guide to Striking Back

Leng Yue (calm, rational, and intelligent, skilled at observation and planning, no romance, focused on fulfilling the original host's wishes and personal growth; she relies on strategy at first, then unlocks auxiliary skills such as medicine, mecha piloting, and special abilities)

Core premise: Bound to the Comeback System (which provides only world information and the original host's wishes, has no independent consciousness, and does not interfere with decisions), she transmigrates through various small worlds, turning the lives of cannon fodder and villainous supporting women around, delivering face-slapping revenge against antagonists, and accumulating "life energy" (used to repair her own soul and unlock higher-level abilities).
