A Profound Sage's Sage Seal was actually dissipating. Such an event was something that had never been witnessed by any practitioner in the universe.
It was indeed possible that there had been Profound Sages who had failed their 'inner demon tribulation', but when they did so, they were no longer showing their divinity, so even if their Sage Seal dissipated, none of the practitioners in the universe was able to see the scene.
But now, due to Sage White's divinity show being broadcast, everyone was able to witness the scene of Eternity's Sage Seal dissipating.
When the Sage Seal completely dissipated, all of the practitioners in the universe felt their hearts tighten.
When the seal vanished, something seemed to have disappeared from their minds. The name 'Eternity', which had been imprinted in their minds, was now gone.
