Traveled to Uncle Jiu's World

I was originally an ordinary high school student, but I died suddenly because of staying up late. When I woke up, I found myself in a strange place. The people here were all wearing clothes related to the Republic of China. Later, I met Uncle Jiu and awakened the ghost-catching system, so I embarked on the road of subduing demons. I also traveled through various Chinas and encountered some historical events. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
