It took roughly 9 hours for Rory and the others to finish forming their immortal rings. They all succeeded, with Rory coming out first and Echo coming last.
While outside, Klaus sensed the moment each of them formed their immortal rings and knew his team had become even more powerful. Of course, as to how stronger they have become, he can only wait for when their cultivation has been restored to the Immortal Lord stage.
While they were in seclusion, his ten clones had scouted rather far ahead.
Not all of them succeeded, though. Six were killed long before they could make much progress. This told Klaus where not to go to avoid danger.
Thankfully, one of the clones reached a vast clearing, where they could easily cross into the northeast wilderness and enter another forest that led to where they had to go next.
So when his team was ready, they left the cave.
