Zhang Wen is transported to the Republic of China era, but this era is quite unusual. There are zombies that open coffins and suck blood at midnight, a female opera singer in a dark pool seeking revenge, a bride imprisoned at the bottom of a well for a hundred years, a pregnant woman who gives birth after only seven days of pregnancy, immortal bandits, and a celestial master who cannot cry. Luckily, Zhang Wen has a system that allows him to fight monsters and level up. "Uncle Nine, I found something wrong with that abandoned church. How about we go in tonight to brush monsters... no, to exorcise demons!"
