Madam Ingrid was not surprised at all by such a gift. Su Yanyi had traveled to so many places, and Madam Ingrid had received news of many things, especially the magical effects of the medicine, which made her very excited.
Madam Ingrid took out a vial of the medicine, opened it, smelled it first, and then drank it without hesitation. She did have that much trust in the Su family.
The effect of the medicine was obvious, an instantaneous boost in alertness and a warm, comfortable feeling that made Madam Ingrid squint her eyes in pure enjoyment.
After a moment, Madam Ingrid slowly opened her eyes and, with twinkling eyes, looked at Su Yanyi and said, "This is indeed a product of the Su family, truly remarkable. There won't be any side effects or rebound effects, right?"
"My grandfather, father, and mother have all taken it," Su Yanyi said earnestly.
