They have already completely mastered the ultimate ability of their four pathways, so the next step for them is to become the high gods of these pathways. They are confident of achieving this milestone and want to acquire more power quickly, so they've decided to do it now.
Aside from the goal of acquiring more strength by becoming a high god so that the acquisition of the last two authorities that they need will be easier, more strength will also make it easier for them to fuse with the authorities of their adjacent pathways.
After all, they are different from other gods in that the stronger they become, the faster they fuse with authorities. So if they improve their strength by becoming high gods now, when they acquire the authority of giants and the authority of guardians, they will be able to fuse easily and quickly with them.
