If it has sentience, then it should be capable of communication.
And if it can communicate, we can talk properly, make friends, and cooperate… We can also threaten, bribe, intimidate, and brainwash.
Of course, making friends is still the best option.
I, Annan, certainly love making friends (with a meaningful undertone).
As long as there isn't a situation where Annan can perceive a line like "I don't know what I did to earn such disrespect from you," the young White-Haired Duke is pretty agreeable and mild-tempered.
However, the problem now is… since this child of the world has not yet been born, it naturally cannot master language. Therefore, communication is an issue.
But this is not completely unsolvable.
Annan gazed at this "child of the world," feeling slightly moved.
If it is said that others are cursed by the world when using spell powers because they are thieves,
then surely there should be no problem when the "child of the world" uses its own powers?
