Initially, the master physician at the clinic believes the dosage of aphrodisiacs and kidney tonics in the prescription is excessively high and fatal, denouncing the prescriber as an "idiot." However, after the young master leaves, the master re-examines the prescription and discovers that the poisons counteract each other, revealing it to be an astonishingly brilliant remedy. He urgently retrieves surveillance footage to find the prescriber. Meanwhile, the young master successfully revives his long-unconscious father-in-law through self-care and elixirs. The entire family is overjoyed when the father-in-law awakens. The mother-in-law reveals that it was her son-in-law who saved him. Upon recognizing the young master, the father-in-law displays an expression of extreme surprise.
