Once someone becomes integrated with the planet, they become the planet itself and can control all things within that world; they can even bend reality.
However, they must pay the price of having their entire being tied to that planet. They cannot leave the place, and once its lifespan eventually expires, they would die with it.
For Ray, this was not an optimal solution. Given the rate at which he was progressing, he could definitely punch and destroy the world. Why would he need to be tied down to an entire planet?
Thus, Ray instantly dismissed this option in his heart.
He also discovered that all the planets had their own planetary beings, and the sun was also inhabited by a peak planetary being.
In fact, all the stars were peak planetary beings, each having their own smaller bodies, like solar systems revolving around them.
There were differences in strength, but Ray knew that these beings were all peak planetary beings.
