"The origin of the Dark Tide... could it be an even more powerful Cursed Beast?"
Is the being capable of forcing the Curse Deity General to choose self-seal a direct descendant of the Kings of Curses?
Or is it perhaps a newborn King of Curses?
Come to think of it, the current seven Kings of Curses have already made the kingdom suffer horribly, barely hanging on. If another King of Curses were to arise, it would indeed lead to the extinction of the human race.
In that case, it would only be natural for the Catastrophic Beast to desperately seal it, and the likelihood of withholding information is probably due to fear of people coveting the power of the King of Curses, thereby desecrating the graveyard. Hence, they fooled the whole world by announcing it as a curse.
The more Benjamin Harris thinks about it, the more it makes sense, and his greedy desire swells up in his heart!
