Er Gen
I wonder what happened to his own Ji Realm. Does he still have it? If so, will he combine the two upgrading his and absorbing it?
It's been too long indeed since we saw the Ji Realm, and this is the first time we see another Ji Realm cultivator besides Wang Lin, and perhaps due to how that guy is sealed in there, could it be that he's the one responsible for the destruction of rhe Celestial Realm? Also one more thing, back on the Demon Land where Wang Lin summoned the divine retribution for the second time and become Heaven Defying cultivator, there is a hint of the Shi Realm as well but it led nowhere since we entered this star system.
