Closed Loop Trial

In Songtaoju, where the mountains were blocked by a snowstorm, a body lay in a locked secret room. Forensic doctor Gu Yunqing put on gloves and bent over to examine. The spots on the corpse appear in places they shouldn't appear, the rigor mortis process does not match the room temperature, and the core body temperature reading points to an absurd conclusion—— The deceased died before anyone could arrive. The murderer is among the six guests with ulterior motives. Criminal psychologist Shen Si uses language as precise as a scalpel to cut open the cracks deep in everyone's memory: tampered childhood, implanted fears, and set trigger commands. Thirty years ago, a memory manipulation experiment code-named "ECHOES" drove all victims into the same cage. The ticking of a pocket watch, the smell of burning pine, the number 7:15 - whenever these signals appear at the same time, the hypnotized person will perform a preset death ritual. But Gu Yunqing came to Songtaoju not just to solve the case. On a snowy night twenty years ago, her parents were killed at home, leaving a jagged scar on the murderer's wrist. That scar is now under Shen Si's sleeve. She had waited twenty years. Tonight, she needed proof. "Closed Loop Trial" is an original mystery novel that integrates forensic science, criminal psychology and hypnosis technology. When the physical secret chambers are dismantled one by one, the real secret chamber is deep in everyone's consciousness - memories can be implanted and behaviors can be triggered, but can free will tear a crack in the programmed destiny?
