In fact, the Star Sand Saint had long since wanted to take Gu Daoyi as his disciple. In his eyes, Divine Fetus was the highest-grade physique in this world, and added with his careful nurturing, not only would Gu Daoyi be capable of inheriting his legacy, he might even be able to surpass him, and advance into the Saint King Tier that he had always yearned for.
It was no longer possible for him to take that step himself, but if he could personally nurture such an invincible paragon saint, he would die happy.
Moreover, if he nurtured a Saint King, Gu Daoyi would definitely remember his good will. Then, even after he had passed, his son would have an incredibly dependable backer in the future.
