It was rather coincidental.
10,000 years ago, Qian Shu Huan became an advanced god and left the Qian family and Descent Mountain City before joining a lord-rank force in the Eastern Ridge Mansion. His position in the lord-rank force was rather low, and he ran errands in the library. Nevertheless, despite his low status, he was still privy to many pieces of news and information since he was in a lord-rank force.
Apart from that, the lord-rank force Qian Shu Huan belonged to was located close to the Glorious Heaven Sect. Moreover, the lord-rank force he belonged to revered the emperor-rank Glorious Heaven Sect. Hence, there were quite a lot of interactions between the two forces; so much so that even a lowly member like him had heard many things about the Glorious Heaven Sect.
