Earth Immortal Realm, Eastern Continent.
Speaking of the history of the Taixu Taoist Sect, there is much to say.
After the Sealing God Tribulation, both the Chan Sect and the Buddhist Sect flourished significantly. The entire Eastern Continent devoutly followed Taoism, particularly venerating Yuanshi Tianzun, one of The Three Pure Ones.
The Taixu Taoist Sect, within the Eastern Continent, could be described as a colossal entity. Its Sect Master, the Real Person of Taixu, possessed a Cultivation of the Daluo Second Layer Heaven. Although he was not ranked among the Ancient Twelve Golden Immortals, his reputation resounded throughout the Eastern Continent, and his disciples numbered up to three thousand.
With three thousand disciples and Daoist Skills reaching the heavens, whether you were a Great Demon King or an Immortal Buddha, in the presence of someone from the Taixu Taoist Sect, you would have to show some courtesy.
