something's wrong after 400years? chanting a spell?
wait a minute .. i think i saw a plot like this where humans are chanting spells and MC(reincarnatred as well) is just woosh woosh this is how you do it
and demons are the ones orchestrating this so that humans would be weak
what the f*ck MC is being scared for? he is just an overpowered sh*t that can disintegrate anything
and same age with Lilliera with that massive badonkers bazookas? how old again is the MC?
