Such power should have turned that island into smithereens
Even before Azief become a Divine Comprehension leveler, if he wanted to destroy an island, he just need to punch it and the force of that punch would flatten every trees and shock every living being before splitting the island into two.
Normal island is like that.
Even a sturdier island would have been destroyed the way those three people been fighting.
With Raymond hurling everything he could toward Kaiju and Kaiju summoning rain water that sis as sharp as sword and lighting like a divine arrow form the sky, that island should either been split into fragment or charred into ashes.
There is no need to mention Sofia who was also shooting arrows of all shapes and sizes and with all kinds of magic embedded into it, that the fact that the island maintained its shape until the end of the battle is nothing short of a miracle
The island is magical.
