Bab 1576: "Inviting Wilhelm To Work In Hell"

These skills were all not related to Ainsley's abilities but more like a general skill that people could get by learning secret techniques, cultivating temperament through countless experiences and so on. 

That's why it's just a little gift. 

But Asmodeus' gift should still be the best. Aside from purifying Ainsley's bloodline and strengthening Ainsley's charm ability.... 

He awakened the skill that the first founder of the Sloan Family couldn't do and the possible skill that this founder should get if he was stronger or had a thicker Asmodeus bloodline back then. 

Turning love, affection, likes, admiration and similar emotions from other people towards Ainsley into energy needed to use the charm ability! 

[This demon lord called it the love battery. Anyway, you consume the love, affection, admiration, and all similar emotions from others to fuel your charm ability.]
