Gang Leader in Black

A modern online novelist travels to a place similar to ancient times, but this place is not like any dynasty in history, and the martial arts here are prosperous, but there is no such thing as internal strength or true energy. Instead, there is just continuous training of the physical body to maximize the potential of the physical body. It is not an empty lie that a strong man has tens of thousands of pounds of strength, and one person can defeat thousands of troops. Watch the protagonist carry the ring of luck and use modern knowledge to make his gang bigger and bigger.
