Conquering the Strongest in Another World Is Easy, Because I'm...?

He hired a childlike vampire progenitor princess who was also a Demon Lord, won over a greatsword-wielding heroine betrayed by her kingdom, and stole the egg of a world-ending dragon girl before it could hatch... To end the war between himself and his biological younger sister, whom he had only just met, Qin Shi had no choice but to conquer the strongest beings in another world and turn them into fighting power. That was how he began his journey, step by step, toward defying the Supreme God.

This is an adventure book from the very beginning, a memoir of a young god and her followers.
