I'm Fighting Zombies in the Republic Era

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!"
