Leng Zirui took the iron box, opened it, and retrieved the letter. Upon seeing the first few sentences, a slight gravity appeared in his eyes.
He read it carefully from start to finish, stopping at the last two letters, "ZM".
ZM?
Returning the letter to the iron box, Leng Zirui was about to speak when a staff member rushed up, "General, we found this in Tang Ming's room."
Leng Zirui turned his head and saw the person holding a vial of medicine. "What is it?"
"A type of sedative, colorless and odorless, can easily dissolve in any liquid, and after ingestion, it can quickly put someone into a deep sleep state," the person answered.
Leng Zirui took the vial and examined it. Only half the bottle remained, indicating a significant amount had been used. Why would Tang Ming keep such a sedative at home?
"What is the metabolism time for this sedative?"
"About a week."
