On a rainy night, Lu Fei fell down and picked up a transparent mobile phone in a puddle.
There is a girl named "Sha Niu" on the phone. She says she is from 2060.
She also said that she could travel through time and space.
At first, Lu Fei thought he was hallucinating.
Until he really stood on the battlefield in the late Eastern Han Dynasty and watched Guan Yu charging towards him with the Qinglong Yanyue Sword...
"Wait! Mr. Guan! Your takeaway! Thank you for the five-star review!"
…
An endless journey through all the heavens and realms.
What Lu Fei didn't know was that in the distant future, a hand tore open the space and sent Sha Niu back to him.
