Ajax assured them regarding their future path; however, before that, they had to become the Emperor Realm Cultivators.
If it was before, the cultivators in the Purple Stone World would have a hard time becoming Emperor Realm Cultivators; however, now, there would be a Standard World Tree in the Purple Stone World, making it almost comparable to a low-level Greater World.
Moreover, thanks to Siora's help, Ajax was able to get some good inflow of World Cores and along with the World Cores he could get from the Golden Demon Territory, Ajax was planning to upgrade all his worlds including the Purple Stone Word into Greater Worlds.
