Pan Shuai, a delivery rider in 2025, was struck by a strange purple lightning while delivering food on a rainy night, and he and his car traveled to the northern wilderness during the Yongle period of the Ming Dynasty. The takeaway box he carried mutated due to the quantum entanglement effect and became an "entropy reducing container" that can control the flow of time to a limited extent. In the wilderness of the Ming Dynasty where the Little Ice Age was raging, this modern low-level worker must use simple technology modified from take-out equipment to fight against the survival crisis of hunger and cold, suspicious border military posts and the mysterious "time rift" being tracked.
When Pan Shuai discovered that every time he used the quantum power of the take-out box, it would cause local climate anomalies, he realized that he was not only a time traveler, but also an "entropy anchor" between two time and space. After getting acquainted with the exiled firearms craftsman, he gradually understood that this time travel was no accident - there was a certain technological resonance across time and space between the watertight compartment technology and firearms research and development of the Ming Dynasty and the modern technology he carried. In order to find a way to repair the rift in time and space, Pan Shuai must use the rider's survival wisdom to open up a way out of the ancient wilderness without changing the main line of history, and finally discovers that the technical code connecting the two eras is hidden in the most basic survival needs.
The story is touching and full of fantasy.
