"Mm, let's observe him for a few months. If Lucius doesn't suffer any side effects, this potion can be used on you and Dumbledore in the future."
After the Malfoy patriarch left, Su Ming said this to Grindelwald beside him in the basement, without the slightest guilt over experimenting on a living person.
The youthful-looking old man touched his face. The taste of Polyjuice Potion in his mouth reminded him that this face was fake.
It would be nice if he could preserve the effects maintained by the Polyjuice Potion while extending his lifespan. Oh well, he could not ask for too much. A longer life alone was enough.
"Your methods are quite impressive. Although I used to reward my followers as well, I would only teach them some new magic or give them a few nice outfits. As expected, lifespan is far more appealing to living creatures. Even I'm terribly tempted."
Su Ming curled his lip. Those things of yours aren't worth much. How could they compare to the value of Leech Serum?
"Only exclusive rewards can ensure loyalty. If Lucius proves that this potion can be used on wizards without side effects, he'll serve us even more wholeheartedly in the future. Everyone has family, don't they? He's actually quite decent—a man who cares about his family. Very easy to control."
Grindelwald flamboyantly smoothed his hair and jumped down from the table. "If he suffers an adverse reaction, you won't give this potion to your little apprentice, right?"

Su Ming removed his armor and changed into his usual suit. "Still, I don't think there'll be any problem with the experiment. Wizards are humans, after all.
