"You were poisoned, so I just used silver needles to acupuncture points to help you expel some of the toxins in your body, that's why you feel better."
William Cole nodded, continuing, "I didn't say anything before because I felt there was something else going on, so I didn't announce it publicly."
Hearing William Cole's words, Derek Jones's face turned very ugly.
"Dr. Cole, do you know what caused the poisoning?" Derek Jones asked after a few seconds of silence.
William Cole contemplated, "Although there are many cases of poisoning, they generally fall into two categories."
"First, your diet is poisonous, and it's the toxicity that has accumulated over many years, not a problem of one or two days."
"Second, the environment you live in is toxic, because you're constantly exposed to toxins."
"Third, this might not be an accident, but intentional poisoning!"
Derek Jones was lost in thought, his gaze shifting uncertainly.
