Quick Transmigration: No More Cannon Fodder, Time to Torment the Scumbags

This is a very short story, with only a few chapters per world, but plenty of stories and experiences.

Feng Jiugue is a powerful figure from a forbidden zone of life, with the ability to live forever and never die. But she is trapped within the zone and cannot leave. Years of solitude have left her yearning for freedom. To make that wish come true, Feng Jiugue created a miraculous technique that allows her soul to transmigrate into different minor worlds. However, the laws of these worlds cannot withstand her overwhelming power, so most of it is sealed away. Because the technique is unstable, each time she transmigrates, she ends up in the body of a minor character who has been bullied or deceived by the worst sort of people.

Without Feng Jiugue possessing them, each of these original characters would meet a tragic end.

No suffering, no saintly self-sacrifice, and no need to overthink things. If I can solve it with my fists, I won't waste words.
