After Reuniting with the High School Idol, He Actually...

I'm Looking for Some Ancient Texts, Thank You

I want to find some ancient writings. The writings from the past really have a special flavor, but this ancient time is not that ancient time. What I want to find is a book with three correct views, no brain-deadness, good logic, and a normal overall IQ. I don't want some ancient dog blood writings with a weak body and a strong will. Thank you, thank you.
