Legion-5's father mocked himself. If he had a world seed then he wouldn't be desperate about cracking the method to become a world god without Supreme laws. He needs the method to gain contribution points so that he can buy what he needs from the Supreme Alliance to become a world god.
He already has his Supreme law so he doesn't care personally about how to become a world god without a Supreme law. What he cares about is the points that the discovery of such a process will grant him.
It is for points that he accepted the mission to provide his essence to produce the next generation of hatchlings. It is for points that he is guarding this plane for the Supreme Alliance. It is because of these contribution points that Tanc830,428,723C became Legion-5's mentor.
