The Supreme Sovereign of the Mortal Realm

"If the people from the Bright Temple haven't tampered with the seal, then why has the Demon God Prison's eighteen levels seen so many Evil-Infected Demon Clan members?"

"Or is it possible that the mysterious figure who descends to the Lower Realm periodically is not here to break the seal but to reinforce it!?"

Gu Lan was startled by his own thoughts. If this were true, it would imply that the sealing point for the extraterrestrial entities might have had issues long ago. The Bright Temple might be trying to remedy the situation too late. This means that all the assumptions and doubts he, Feng Yang, and the Demon Emperor had previously need to be reconsidered from scratch...

However, it's certain that the extraterrestrial entities have already infiltrated the Demon Realm. This situation is possibly even worse than having a single broken seal. The extraterrestrial entities have escaped and are lying in wait, potentially creating countless Evil-Infected monsters.
