万物发明指南：时间旅行者生存手册

The blend of humor and technical advice is so unique—I'm curious what sparked the concept of turning history into a DIY manual for stranded adventurers.

The book made complex inventions feel accessible with jokes, but I wonder if that approach helps or hinders retention for others.

It feels like a curated list that balances humor with practical knowledge—I'd love to know what guided those choices.
