Rebirth Begins in Private School

The protagonist, Su Mo, is an ordinary modern auto repair worker. By chance, he was reborn in ancient times. At first, he served as a teacher in a private school, teaching and educating people. I thought it was a plain life, but instead I couldn't help but sell illegal salt, fight gangs, and kill bandits. He even got involved in the historical tide of changing dynasties and finally ascended the throne and proclaimed himself emperor... This novel and its characters are purely fictitious.
