The way Heinz looked at Zatiel right now was the same stare one would give a madman.
"Are you suicidal!?, if we try to attack the Heavenly Creator World, we will be erased from existence before touching the surface. Even the entire military might of the Magi World would not be enough to invade it. That is a world that can equal the Abyss and Baator in regards to power."
All High Worlds were not equal, and despite the Magi World being a supreme power in the universe, it was too young, and the amount of Being of Laws that has produced could not compare to the other worlds and planes that have existed for hundreds of billions of years.
When someone becomes a Being of Laws, they become challenging to kill, to the point that they are considered eternal and share their life with the laws. Even though maybe less than one person in one hundred billion can become an entity like that, with enough time, their number could reach the hundreds easily in a High World.
