Lin Lin, the youngest senior mechanic at the Imperial Academy of Sciences, accidentally traveled to Earth during a gravity experiment - a "primitive civilization" with no psychic powers, no interstellar battleships, only walkie-talkies and crude electronic equipment.
To make matters worse, his brain-computer translator is damaged.
"I'm from the Empire" → "I'm from a place to eat"
"Repair psychic mecha" → "Repair aircraft"
"Thrown out by the gravity field" → "Thrown out by the washing machine"
As a result, this mechanic who once stood at the pinnacle of science and technology became a "second-grade psychopath" in the eyes of the Haizhou City Public Security Bureau.
Criminal police captain Zhang Lei suspected that his brain was broken. Technician Lao Liu discovered that some of the "mechanical terms" he said had a physical basis. Intern Chen Xiaoyu was curious about his "little invention"...
From being regarded as a suspect for falling from a building to using a mechanic's skills to solve the case of a smart car losing control, Lin Lin's life on earth is full of ridiculous misunderstandings. He complained about the earth's industrial design that "tolerances are measured with feet", using white noise to interfere with the chip's resonant frequency, and using scrap parts to piece together signal generators - in the eyes of earthlings, this is simply magic.
But in this "technological wasteland", an imperial mechanic is using his unique way to redefine what "solving crimes" means.
This is where the daily life of a hard-core alien mechanic on Earth begins.
