Seek Dao Sect operated many businesses which provided various entertainment services for its cultivators. Cultivation wasn't practicing in seclusion to death, and an uninteresting life would not lead to immortality, hence the entertainment businesses were vital.
For instance, the aforementioned Sichuan Hot Pot and the Hundred Fragrance Building which the trio were heading to.
Lu Yang had heard that Seek Dao Sect used to not operate in this manner. Previously, cultivation was cultivation, indulging in these miscellaneous things could hamper one's devotion to seeking the Dao.
But once the older Sect Leader and Elders retired, and the new Sect Leader and his eight Elders took control, Seek Dao Sect took on a whole new life, encouraging their members to strike a balance between training and leisure.
In their words, if these things could affect one's devotion to seeking the Dao, then they're not fit to become immortals.
