(This is a new book. I hope you will be patient. It will get better and better in the future.)
When a young teacher who loves history mistakenly travels to a parallel world, he has a system that is standard for travelers.
Rewrite the world? It looks easy.
"System, what can you give me?"
"The position of a coal mine, whether a person has lied, and when you go the wrong way, I will be silent."
"That's all?"
"That's enough."
In 1901, he started from an iron mine.
In 1914, the world discovered that some things were no longer under their control.
