The interactions between Fang Bai and the Blue Sea Sect were limited, but because he killed Elder Han Dongweng of the Blue Sea Sect and his disciple Yang Heng, he became the sect's mortal enemy.
When Han Dongweng and his disciple were slain, many powerful practitioners witnessed it. After learning it was Fang Bai's doing, the Blue Sea Sect dispatched their strong practitioners to hunt him down. However, Fang Bai, accompanied by Shi Xiaolian, left the Yunhai Sect and flew all the way to Immortal Stone City, thus eluding the sect's pursuit.
Fang Bai was unaware that the Blue Sea Sect had issued a bounty order across the entire Three Thousand Worlds, offering a substantial reward for his head. Fortunately, the order was issued not long ago and had yet to reach the Fan Hai Sect; otherwise, Fang Bai would have faced trouble aboard this sea vessel.
