"The Cold Crystal Fragrance has a unique scent."
Hei Gu walked up to Imperial Physician Lang, "Imperial Physician Lang, the scent on you is the scent of Cold Crystal Fragrance! How do you explain this?"
"You... you are blatantly making false accusations! I did not poison the Crown Prince, I am an Imperial Physician, I save lives, I do not kill!" Imperial Physician Lang turned red in the face, repeatedly explaining.
Hei Gu said, "Your Majesty, the true cause of the Crown Prince's death can be determined by summoning other Imperial Physicians. If what I, Hei Gu, say is correct, then Imperial Physician Lang cannot escape blame!"
The Ghost Emperor decided immediately, ordering people to the Imperial Hospital to summon three Imperial Physicians. After verification by the three Imperial Physicians, the Crown Prince indeed died from inhaling too much Cold Crystal Fragrance.
