Rain was satisfied with the result… but hearing all that math was starting to haunt him. He liked math more in middle school when there were actually numbers in the calculations, not like they were nightmarish descriptions like this: a2 +b2 =c2 or this ∀a,b∈G,∃x∈G such that ax=xb.
In any case, little by little, Rain increased the size of the vessel by making its interior made of helium when he had enough mana to expand it. For now, that wasn't a problem, but eventually, they will have to increase the amount of land and mass for cultivation as well. Unless they wanted to do some population control, and he didn't want to do that. He couldn't be a hypocrite when he was always trying for opportunities to score with his wives, after all.
