Yin Feng said, "Axu, let's administer a polygraph test to Fu Wenxiu."
You Mingxu was taken aback.
Yin Feng stated, "Earlier, I saw a lie detector in the storage room next to the forensic department. I suddenly recalled, I know how to use it, I learned from my teacher."
Huai City is an important city in southern Xiangxi, so having a polygraph isn't surprising. There was a period when the entire province was encouraged to learn this skill, but after all, it's a new thing. Being not absolute evidence, it's not widely used in the counties and cities, hence the machine was left there.
You Mingxu queried, "Is that thing useful?"
Yin Feng replied, "We won't know until we use it."
You Mingxu nodded her head, "Sounds good." She thought that even if it was fruitless, frightening Fu Wenxiu could be a good idea, or even probing him.
"Do you think it's him?" You Mingxu inquired.
