I Became a God by Spending Money in Games

I’m Out of Things to Read, Fellow Bookworms

Any diary-System stories where the protagonist reveals from the start that they know someone has a dungeon? Not that kind, please!! Dual transmigration into a book is fine too, but whether it’s Western fantasy or ancient times, enough with making guns and cannons and stringing up power lines. Cold weapons should feel like cold weapons! At least a million words, please.
