With the subsequent doors opening, they indeed found the statues of the Six Divinities, still in their complete forms—such statues are no longer describable in the current era!
"I suspect that behind the last door is a sculpture of the 'Emperor of Blood,' but the divination shows danger," Tao Yu spoke up.
"That makes some sense, but would the 'Emperor of Blood' be placed together with the Six Divinities?"
"I think all four emperors might be True Gods."
Tao Yu had no particular faith or irreverent thoughts of the sort, so he wasn't bound by such restrictions.
Klein had read many diaries before, but in the past, he had been partially constrained by thoughts regarding the True God. He guessed that the battle of the four emperors was for becoming a god, and that the 'Underworld Emperor' eventually became the God of Death.
Now, suddenly hearing Tao Yu point this out, he too felt an epiphany washing over him.
