It was apparent who these two were.
Gravis' father and the highest Heaven.
However, when Gravis heard that his father managed to come out of such a gate alive, Gravis felt some excitement.
It was inevitable that Gravis compared himself to his father. After all, Gravis had no one else he could compare himself with.
The normal Cultivators were not even close to his level anymore. So, he couldn't compare himself to them.
This only leaves the Heaven's Magnates, his father, and the Heavens.
Gravis had only met one Heaven's Magnate before, which was the Black Magnate, but he hadn't heard anything of his past. The lives of the Heaven's Magnates were still a mystery to Gravis, which basically made it impossible for him to compare himself to them. One can't compare oneself to something that one knew nothing about.
That left his father and the Heavens.
