A sects lifeblood would first be their defensive capabilities to keep the headquarters alive but secondly would be their disciples!
A sect with no disciples couldn't call itself a proper organization as it would be only an empty shell.
Yun Jhin needed a few things to make the sect attractive to those who wanted to join.
The first and the most important thing would be the carrot and the stick, aka benefits.
There wouldn't be problems to those below the middle stages of the God Realm as he had one whole planetary Bazaar under his thumb which he could use to siphon resources to his sect, he couldn't really drain them as it would be bad for business but there were many businesses that he could take at least 1 or 2 percent out of them which in turn would get him quite a lot of resources.
He could even gain resources for average God experts, at least those below the 4th stage could be accommodated in the sect.
