After Traveling Through Time, We Came to a Different World!

This is my debut novel. The details may not be very good. Please forgive me. Or you can treat this as a joke. I just want to see if I have this talent. Maybe it will be finished. I will try my best to finish this novel or light novel. I don't know how to explain this, and I hope everyone can click in with a hopeful attitude! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
