Gu Zhiqi spoke, glancing at the tea on the coffee table, then picked up the teapot and gently shook it. She looked at Fu Xiyan and asked, "He drank this tea while talking to you, right?"
Fu Xiyan nodded.
"It must be in here." Gu Zhiqi said, pulling out an acupuncture kit and a small porcelain bottle.
Taking out a needle, she inserted it into the porcelain bottle to soak for a few seconds, then drew it out and inserted it into the teapot.
When the Silver Needle was taken out again, a layer of black had appeared on it.
Fu Xiyan was stunned for a moment, then felt a surge of fear mixed with relief.
Just now Qi Rui poured him a cup of tea. Fortunately, he had been cautious and didn't drink it.
Qi Rui stared at the black layer on the Silver Needle, also stunned, "How is this possible? I brewed the tea myself, using leaves that I had personally kept. I've been drinking it for a long time without any issues."
