In the past, Ethan didn't join the Greenfire Sect despite having a good cultivation because he only had an Inferior Spirit Root.
However, things have changed now.
Currently, he had a High-Grade Spirit Root…even though it was temporary, the Sect won't find it suspicious because there were many cultivators whose lives were changed after entering the Secret Realms…especially the Secret Realm like the Mystic Soil Domain.
So, he no longer had any problem joining the Greenfire Sect.
"You two, will follow me to the Sect to complete the procedures. After that, you can either live in the sect or live with the Lin Family."
The sect never forces any of their disciples to stay within the sect. They could live anywhere they want, roam the world, experience various crises, and become stronger.
However, they had to complete the mandatory missions issued by the Sect and return to the sect when they were needed.
