Gu Yu nodded and asked, "Dr. He, will there be residual traces of these two drugs after they're injected into the body? Will we be able to detect it if we conduct an in-depth test?"
"Any drug that's injected into the human body will always leave behind some residual traces. We'll be able to pick it up as long as a test is conducted," Dr. He answered matter-of-factly.
Gu Yu narrowed his eyes slightly and, after a brief pause, asked softly, "Are there cases of exception?"
Dr. He smiled and replied, "An average doctor would claim that there are no exceptions, for there is a limit to the digestive capabilities and metabolism rate of the human body. If there isn't a long lapse between the time of testing and the time which the drug is injected, there'll always be traces of it left. Besides, with how advanced medical devices are these days, it's highly unlikely for there to be an error with the result."
