Bao Yan, on the first day of graduate school, he was knocked unconscious by a handsome guy and traveled through time.
When she woke up, she was in a strange bed, with people around her speaking words she didn't understand.
She didn't know what year, month, where, or who she was.
A man comes to accompany her every day, and Bao Yan can only communicate with him in sign language.
One day the man took her out to play, and she looked at the embarrassment of thousands of troops under the city wall.
He looked at the beacon on the city wall again and smiled bitterly.
"It turns out I am Bao Si."
