The Five Elements aura from the Five Elements World of Cangqing appeared in the aura of Ding Huan's tribulation, which could only mean two possibilities.
One is that Cangqing willingly gave his Five Elements World to Ding Huan, the second is that Ding Huan killed Cangqing and seized his Five Elements World, or he stole the Five Elements aura and fortune from Cangqing's Five Elements World.
The first is highly unlikely; Yuanqing knows Cangqing somewhat.
Selfish and self-interested, it is absolutely impossible for him to give his Five Elements World to anyone, not even to his own father.
Then there's only the second possibility, that Cangqing was eliminated by Ding Huan.
But how could this be possible? Even if Cangqing is not a Divine King, he's at least a late-stage World God; how could Ding Huan defeat Cangqing?
Although there's a rumor that Ding Huan and Mo Changcan killed a Divine King on Dao Ruins Street, the main power was likely Mo Changcan, right?
