[A highly intelligent forensic examiner, Yu Sheng, with retrograde amnesia X a genius profiler, Si Yu, with Asperger's syndrome]
Yu Sheng and Si Yu met three times in all.
The first time was at a hostage scene. Yu Sheng was the victim who had been taken hostage, while Si Yu was the calm negotiation expert.
The second time was at the Yuecheng Public Security Bureau. Yu Sheng had become the new forensic examiner, while Si Yu was the widely acclaimed genius profiler.
The third time was on the China-Myanmar border. Yu Sheng was an undercover agent in the darkness, while Si Yu was a police officer in the light.
"I am a silent mountain, yet I never imagined that one day I would stir for you."
