I don't think he'll become a demonic race. I mean, he doesn't even ask for help to the sealed god-
I've read spoilers from the novelupdates forum lol
There's no reward from the test (as far as I know), and he'll investigate the puzzle city, a city which abandoned by gods. Maybe next arc we'll know the answer why the gods abandoned some cities and races (like the wolf tribe)
Nahhh don't think so... I think bye might be mean that alberu succeeded and saying bye for now to WS or Cale is saying bye to the dimension he is currently in. I saw an artwork from a korean where KRS pushed Cale back to the light... I think KRS of that dimension will take over and push Cale back to Raon and everyone's dimensions... I heard that the raw of the noble is over 650 right now... Unreliable source in my end... Language barrier sucks lol
