The Goddess of Time Travel

Shen Xinyue woke up and looked at the beautiful girl in front of her who called her Miss. The girl told her that she fell into the river and had been comatose for two days and two nights. Shen Xinyue was thinking that she was poisoned during a fight while trying to save someone at the village, so why did she fall into the river? Look at these strange houses and strange people. Have you traveled through time, or is this what the underworld is like~
