Li Yu had been contemplating the future of the Double Rest Sect from the very beginning, not just to ensure a stable belief system and earn more rewards, but also in the hope that what he established here could continue to endure.
And the divine right of kings was the path he chose after much reflection.

Of course, Li Yu did not hide from the girl the problems that the divine right of kings might bring; in the long run, these two elements would surely counterbalance each other.
Moreover, the theocracy established by Li Yu would certainly dominate over royal power, at least in his generation.
