Killing her to silence her was undoubtedly the best way. Madam Zou was not someone of high status. If they wanted her to shut up, the person behind the scenes could have killed her instead of poisoning her.
"I'm not sure either. Perhaps they're looking for a suitable person to test the effects of the poison..." Gu Qingxue's voice was so soft that it could barely be heard.
Judge Wu did not hear her clearly and looked at Gu Qingxue in confusion. "What did you just say? I didn't hear you clearly."
Gu Qingxue did not answer him but sat down to take Madam Zou's pulse.
Madam Zou was like a silly zombie. When Gu Qingxue touched her, she did not resist. She just stared at the sky in a daze and continued to laugh.
