After the meeting had ended, the three direct descendants of the Intercepting Sect's guardian immortals gathered privately.
The Honored White Bone's expression obviously showed some discontent, presumably because the Blood Sea Ancestor had announced the recovery of the Myriad Avatar Absolute Immortal Sword without having informed him in advance.
As the saying goes, when it's time to make a decision, people often won't wait until the public meeting to do so.
In fact, the higher echelons of the Six Paths have traditionally held meetings beforehand to decide on major strategic issues; it was the Blood Sea, White Bone, and Zi You who first gathered to make decisions, and then formally allowed the Sect Leaders to attend the Six Paths council meeting to seriously discuss and debate the matter.
