Shitou couldn't help but find it amusing when he thought about how Master Mi had almost dropped his jaw in shock at the time.
"It is said that he closely guarded the recipe all by himself, in the name of secrecy, and he hadn't even passed it on to his own son. Apart from the most common herb which was directly harvested to feed the ducks, he personally went to the pharmacies in the city to buy the other herbs, ground them into powder, and secretly mixed them into the feed."
"So apart from Mrs. Mi knowing that something else was mixed into the duck feed, no one else had the slightest clue. Even when cooking the ducks, the powdered herbs were mixed with the seasonings, and he would only prepare roughly the amount needed each time, preferring to dispose of any leftovers rather than keeping them."
"Such secrecy is indeed tight enough. But doesn't he fear that if something happened to him, the secret recipe would be lost forever?"
