Huang Liang's evidence... is almost in hand!
By my estimate, it should be around the 17th, at most four or five more days.
This was the deal he made with Huang Liang, otherwise gathering clues would be difficult, even for the police!
Why?
"Some participants in human experiments consented voluntarily, but their subjective consent does not affect the objective legal crime."
"Since it's a crime, the police need to investigate, but... these people actively hide their whereabouts, there's nothing to investigate, we don't even know who they are!"
"Additionally, Han Chengguang is the head of the pharmaceutical enterprise, but doesn't handle drug research."
"Even if you expose it all, all he knows is that he's conducting illegal experiments, he has no idea about the experimental 'consumables'."
Outside the court, Xu Liang slowly spoke.
"Only Huang Liang, he's the main person responsible for the human experiments!"
