Wang Xu stared at Gu Jiao, dumbfounded, "What are you doing sticking needles in him?"
"Coercing a confession," Gu Jiao said.
"You can coerce a confession with just one needle?" Wang Xu expressed disbelief.
Gu Jiao didn't tell him it was a hallucinogen, to avoid him overthinking and assuming that Gu Jiao was manipulating the killer's confession.
Gu Jiao watched the killer lying on the ground, his tense body gradually relaxing, understanding that he was experiencing hallucinations.
She couldn't let him go too deep; otherwise, if he completely lost contact with the outside world, he wouldn't hear any exterior sounds.
Gu Jiao tapped his shoulder with a rolling pin, and said sternly, "If you don't want to suffer more, speak quickly. Who exactly is the killer?"
Gu Jiao had knocked the man unconscious long ago, and had only waited for Wang Xu to come over so that he could hear the killer's name firsthand.
The killer didn't struggle much and confessed honestly.
