Either way, the Ember's sect has been damaged incredibly hard by the war and was still in the process of recovering.
The Founding Elder was very strong, and the continent where they were right now was tier 2.
Back in the day, the Founding Elder of the Ember sect created a technique that allowed one, after reaching level 20, to create an incarnation of oneself that required consumption of half of your ember power that would recover only after the incarnation disappeared.
The incarnation would live for at least 1000 years and directly linked with the owner's mind no matter how far away or where it was.
That is how the Ember's sect was able to travel and discover an incredible number of lower-tier continents and leave their legacy there. With that skill once again being used by the Grand Elder's like Volta caused the sect's recovery to accelerate incredibly fast as the best geniuses of the entire world slowly appeared inside the Ember's Sect.
