The Lord of Yin and Yang: the Watchman from Heaven

Qin Bang, a fat man who was overwhelmed by life and wanted to die, accidentally traveled to the Yan country and obtained the "Fengtian" system to become a watchman. "The Fengtian system has been activated. Hello, caller." "System? Watcher? Traveled through time?" "Yes, welcome to Yan Country, the Lord of Yin and Yang...." Qin Bang, who originally had no hope in life, actually found his destination in a strange world. Activate the golden finger... The destiny of becoming the master of yin and yang begins... "No, you are trying to trick me into the system, right? Isn't my system just cheating? Why do you still need to sign in to upgrade?" "Emmm... You must have read too many novels. How can I be stronger if you don't upgrade?" I heard the system let out a despicable laugh. Lord of Yin and Yang... The people and ghosts of Yan State have been waiting for you for a thousand years... This novel and its characters are purely fictitious.
