Through big data analysis and the judgment of a super AI, it was highly probable that the Demon Bone had been concealed by someone.
What use would a person have for a Demon Bone?
Either it was to create obstacles for Ruan Muhuan's ascension, intentionally causing her trouble.
Or it was to frame and entrap a certain power; such despicable maneuvers often occur among those with authority, especially in a place like Wudou where various powers stand together, and are unified under the control of Wuting. To suppress their adversaries, some old Sects and strong powers would easily exploit the absolute authority of Wuting to their advantage.
Wu Hen's final analysis was that it was either targeted at Ruan Muhuan, to suppress her ascension, or it was to eliminate a certain power with Ruan Muhuan's hand, using her as a pawn.
The Demon Bone had surfaced on its own, and it happened just two days before the last Rotating Martial God's term.
