317 Chapter 217: He is a Medicine Man

Marquis Mu Houchu's complexion became much worse. According to his understanding, this medicine was extremely difficult to synthesise. Even if it could be used on a black bear, it couldn't be used on humans. The last time in the palace when he saw the bear go mad, he thought of this drug. Yet he never thought that Old Man Chen had been able to create a version of the drug that could be used on humans.

At the same time, even if this drug for humans was successfully developed, the most difficult thing was to find a person capable of enduring the effects of such a drug.

Ordinary people simply couldn't withstand the torment of this drug. Basically, if they were infiltrated by this drug, they would die instantly. Only those with extremely high talent, whose bone structure and meridians could be considered extraordinary, could resist it. It was really flattering to think that Old Man Chen had not only found someone who could withstand this drug but was also willing to use it against him.
