Su Yuan, an eighteen-year-old rural boy, was born with a pair of animal ears that can capture ultra-frequency sound waves. He went to the city to collect medical expenses for his seriously ill sister, and was accidentally involved in a jewelry robbery. The stolen goods in the sewer 300 meters away were locked just by the slightest sound of metal friction on the surveillance camera. The police made an exception and hired him as a special adviser.
Since then, strange crimes in the city have been solved frequently: twin murderers were identified by a broken hair, the disguise of a serial arsonist was revealed by listening to the heartbeat, and the crisis of a shopping mall collapse was even predicted from the resonance frequency of the building. The media called him a "humanoid radar" and Su Yuan became the youngest legend in the city.
Just when he stood at the peak of his life, a confidential file revealed the truth: the laboratory fire thirteen years ago was not an accident, and he was "Experimental Subject Zero" who was forcibly implanted with animal genes. The sister who had always been dependent on each other was actually the special commissioner in charge of the destruction project back then - she was not seriously ill, but the suppression chip in her body was about to fail. Once she died, Su Yuan's transformation into a beast would be irreversible.
A deeper conspiracy has emerged: all the bizarre cases in recent years are caused by the remnants of the laboratory testing the limits of his abilities and collecting data for the launch of the "New Human Weapons Project". The next order was for him to personally destroy the city that had taken him in.
The red light of the surveillance camera turned on, and a cold electric voice came from the ear: "Su Yuan, the game begins."
He took off his hearing aids and decided for the first time that he couldn't hear anything.
