Although Li Weide had intended to win Dumbledore's trust with those words,
they also genuinely reflected his concerns about Ancient Magic.
Because when he said those things, he had in fact been telling the truth.
So Dumbledore's answer still gave Li Weide quite a bit of insight.
For example, Ancient Magic had no side effects.
That intense craving he felt for Ancient Magic was really just his own desire at work.
And when he thought back, he had not agreed to that "senior's" request, choosing to refuse instead.
Afterward, even after using Ancient Magic, he had restrained the urge to go back and ask the "senior" to change her mind.
All of that showed that he had indeed kept his desire to obtain more Ancient Magic Power well under control...
However... although Dumbledore believed in his self-control, Li Weide himself still had doubts about it.
Hadn't that "senior" also claimed, in front of her teacher, that she could control her desires? The outcome had not been very good...
Dumbledore saw Li Weide's tightly furrowed brow and knew his words had not reassured him about his own self-control.
"Weide, always remember that you are not 'fighting' alone. As your professor, it is my responsibility to help you master Ancient Magic."
Li Weide made a helpless expression. "If I simply don't use this power, wouldn't there be no problem at all?"
"Being able to control yourself and refrain from using it is proof of your outstanding self-control too, Weide... But in my opinion, it is better to guide than suppress. If you keep restraining yourself and never use Ancient Magic, the difficulty will be far too great. You might as well use it without worry, and only control the extent to which you use Ancient Magic... That would be much easier."
