"System, how many times can this bottle of impotence potion be used? Can it only be used on one person?"
To facilitate his next plan, Harry asked cautiously.
The bottle of impotence potion was as big as a Coke bottle. Harry estimated that it should be usable multiple times, right?
[Reporting to the host: The efficacy of this potion is 100 years, meaning that if the same person drinks it, the effect will last a century.
If only a small amount is given to different people, the duration will vary depending on the dosage. If the goal is to render a target impotent for ten years, then ten targets can be affected.]**
"Interesting! Haha!" Harry chuckled foolishly. It was unnecessary to make someone impotent for a full hundred years—after all, most men would naturally lose their virility by their seventies.
