All the powerful disciples of the Xuandao Sect, upon hearing that the sect master was willing to give away such a supreme treasure, did not hesitate and rushed to petition, hoping to arrange for their own disciples to enter the Heavenly Mystery Space. After all, they would not let the benefits slip away, and they naturally wanted to strive for their own.
At first, the Xuandao Sect Master was determined to refuse and would not agree. However, later, the Dream Trace Daoist came to visit alone and managed to persuade the Sect Master, presumably by offering some valuable treasures.
Because of this, the Xuan Dao Sect Master made an exception, allowing Dream Trace Daoist's disciple, Bai Wuheng, to enter the Heavenly Mystery Space and retrieve the treasure.
Once the first exception was made, it was difficult to explain to others. Therefore, the Sect Leader changed the rules, allowing other disciples to enter the Heavenly Mystery Space as well, which led to the current farce.
