The Author Goes Mad After Repeatedly Transmigrating into a Book

Pure imagination

A struggling author, frustrated by poor statistics, starts writing whatever she wants, throwing the plot into chaos and sending everyone flying. The world collapses, and she is transported into the novel she wrote. To return to her original world, she has to correct the main plot.

The protagonist's golden finger is a blank book. Whatever she writes in it can change reality, but there are limits: the higher her level, the more she can alter.

Leveling up, wasteland, feel-good power fantasy

I'll revise the blurb when I have time. If you're interested, feel free to bookmark it for now.

Theme: Don't go off the rails for no reason
