Two elders have passed away, one of whom Lu Bei had met before, his name being Wei Hong, who had delivered a speech on behalf of the Imperial Sect at the Iron Sword Conference, teaching a real lesson to the sword cultivators present.
He was not only skilled but also adept at speech-making, capable of off-the-cuff two-hour long talks.
Ignoring his talkative nature, Wei Hong had a late-stage Void-refining Realm Cultivation and was ordered by the Elder Court to guard Yue Province; his abilities shouldn't be underestimated.
Both he and the other elder were killed almost instantly and silently—something impossible for Lin Buyan with his abilities to accomplish.
Having great power wouldn't have made it feasible either.
So, first off, Lin Buyan's involvement was ruled out.
