(Time travel + no system + no heroine + no Virgin.)
Liu Xun, a struggling college student with schizophrenia, inexplicably traveled through time while sleeping at home. Is this a distortion of human nature or a loss of morality?
"How do you think we traveled through time?"
"How did I know? Maybe the sun and the moon shine together? There can't be a god with nothing to do. Send it in for us."
A certain god said: "Hey, someone seems to be talking about me."
