In the Neon City of 2190, holographic advertisements cover the sky, mechanical prosthetics and genetic modification have become the norm, but a series of unsolved cases have broken out one after another. Former consortium consultant {Lu Lin} accidentally activated the "Detective System", which can analyze traces on the scene and simulate the criminal process. However, because he was framed, he could only pretend to be an ordinary detective.
He partners with Su Qingyan, a scholar who is proficient in extraterrestrial civilization and mechanical engineering. When pursuing the case, he is involved in multiple forces: the heartless ex-husband steals Su Qingyan's alien research results and colludes with the bully Zhou Hu to suppress the two; there is also a mysterious organization from the "fairy world" that wants to seize the system and control the cyber world.
During the investigation, Lu Lin made a joke because he didn't understand alien customs, but he gradually uncovered the truth through system upgrades, and finally eliminated the heartless villains, bullies and "fairy world" villains, and restored peace to Neon City.
