Quick Transmigration: The Mad Host Is Bound to a Redemption System

(The first part is the author’s spontaneous idea, so the pacing might not be great. Feel free to start from the ninth world.)

After her parents were murdered, Xie Bing took revenge with her own hands. Right afterward, she was captured by something calling itself a rescue System.

She transmigrates through different worlds to save the timid original hosts.
