He didn't think that boss Bai was the type of person who would steal the recipe, but Lin Yi wasn't familiar with him yet, so he didn't tell him about one of the ingredients. Boss Bai also said that he could make one mistake!
Hearing Lin Yi's words, boss Bai's eyes went from the initial teasing to seriousness! He'd come up with this question on a whim, trying to make things difficult for Lin Yi so that he'd stay in school. He had some medical skills, but there were still a lot of things he didn't know-and Lin Yi just said the recipe out of nowhere! Boss Bai's eyes were wide open!
Lin Yi's guess was right-he wasn't trying to get the recipe for the injury medicine, because he didn't even know that Lin Yi made it. Otherwise, he wouldn't have come up with this question. He'd tried to figure out the injury Medicine's recipe before, and of course, with his abilities, it wasn't hard to figure out the recipe.
