(Period setting + spatial dimension + taking down scumbags + turning the tables + scientific research)

Reborn on the day she was set up and pushed into the water, Wen Wanlan turns the tables, foils the schemes of those ungrateful wretches, and clears out all the scumbags' good stuff.

Her grandparents play favorites, hiding valuables for their biological grandchildren. Wen Wanlan secretly clears them out, leaving her grandparents with nothing to show for it.

Her uncle gambles recklessly, racks up debts, and hides things to pay them off. Wen Wanlan secretly clears those out too, cutting off her uncle's family's escape route.

Her cousin schemes to steal her true identity, so Wen Wanlan clears out the money and jewelry she's hidden away.

A scumbag man frames her and forces her into marriage to serve as his unpaid housekeeper, so Wen Wanlan keeps clearing out the money he's secretly stashed.

When Wen Wanlan runs into scumbags, she hits back whenever she can and empties their homes, leaving them with even less.

But one day, Wen Wanlan meets a calculating man. Before she even has to lift a finger, he's already emptied his own fortune and handed it all to her.

His inexplicably eager behavior leaves Wen Wanlan at a loss.
