"Wen Shouyi sent it to Qingying?" He Zhichu's frown deepened. "Where did Wen Shouyi get the photo? Or was she following me? Did she know that I gave her parents' hair and blood samples to you?"
The time and place shown in the photo was the exact afternoon when He Zhichu had sent Gu Nianzhi something.
Gu Nianzhi shrugged. "I'm not sure about that. I thought that once I caught the person who had taken the photo, I would be able to trace it back to Wen Shouyi."
Following a pause, He Zhichu said, "Although the person who took the photo committed suicide, Wen Shouyi has the photo and forwarded it to Qingying. That's enough evidence to investigate her."
He Zhichu was also a barrister. Although he had joined the army, he had studied law for many years and had then gone to practice law in the opposite world. He was like Gu Nianzhi, who liked to think and act within the framework of the law.
