The period after Second Prince's sudden assault was hard for Noah. The second activation of his ambition hurt his centers of power and made them too frail to endure the power that they contained.
His body struggled to contain the strength that it carried. The weight of his other centers of power also became almost unbearable, and only the dark matter flowing inside his tissues managed to keep them in one piece.
His mind felt heavy, especially since Noah could stop the production of new mental energy. Cracks appeared on his mental sphere due to the internal pressure that pressed on its walls.
Noah also felt confused. His body couldn't fully contain his sea of consciousness, so he would black-out for a few instants every once in a while.
His dantian had it a bit easier than his other centers of power due to the almost absence of darkness in its insides. However, the muscles pressing on its walls made it regress by a few years.
