A common citizen in the 21st century - Cai Xiaobai has traveled through time! Cai Xiaobai has done a lot of bad things in her life, and she is a 17-year-old high school girl. I wonder if God is stupid this time and let her travel through time! But God still loves us very much, and sent her to a hellish place where chickens don't lay eggs and birds don't poop, but... Let her meet a handsome guy who makes people spurt blood... God is unfair~!!
