Within just seven weeks, the improvement to the Worldeater Broodmother was clearly visible to anyone who could see the enormous insectoid creature. He was feeding the Worldeater Broodmother his Mana for seven whole days without a stop.
And only now was he starting to feel some drain on his Mana because the healthier and stronger the Worldeater Broodmother became, the more of his Mana she was able to assimilate and devour.
Right now, she was in some kind of baby stage, and she needed a lot of Mana as pure as possible to fuel her growth. Even though his Mana Regeneration has reached literarily insane degrees, the same could be said about the consumption rate of the Worldeater Broodmother.
Fortunately enough for him, as the Principality Eldritch Angel, he still had some advantage when it came to this area because his Mana, together with his Mana Qualities, was far more superior to the other beings.
