The female protagonist transmigrates to various small worlds to save the pitiful and helpless, saving others and herself along the way. (If it's not your thing, don't read or leave hate comments.)
The worlds include:
Matriarchal society, a lie-flat tiger, a xianxia sword cultivator, a troublesome seductress, Republican-era romance, face-slapping a scheming green tea... All sorts of things, with a pace that speeds up and slows down. I'm sure you'll be satisfied.
The stories will get better and better as they go. I hope you can point out any shortcomings, and I'll keep improving~
