Gu Yuan was once a genius profiler in the police force and cracked many high-IQ serial cases. Three years ago, when he and his partner Chen Du were investigating a strange case, Chen Du died in an unexplainable way in front of him - his body turned to ashes in a second, leaving only a line of charred words on the ground: "Observer, welcome."
Gu Yuan was deemed mentally insane and was forced to leave the police force. He began to investigate the truth about the death of his partner alone. A year later, during a late-night investigation, he triggered an invitation from the "system" and was pulled into the infinite world.
Brain-burning. Nice
