Xu Nian had no information at all about the Blood Demon Sect's mysterious Sect Leader. Even people in Jianghu seemed to have never truly seen him. However, there was no doubt that the Blood Demon Sect had the backing of people from the Imperial Court; otherwise, they wouldn't have been able to transfer the Brocade Guards away.
The Blood Demoness knew that Xu Nian was planning to make a move on the Nine Dragons Secret Treasure. She was also aware of the special nature of the Nine Dragons Secret Treasure at that time. But apart from inquiring about the Sect Leader of the Blood Demon Sect, Xu Nian was also very concerned about his own affairs.
