Even though he is so weak right now, that even a bolt of lightning could disperse him into motes of energy like dust, because of the blessing of the Heavenly Will, he could remain hidden
And it is also because of the Heavenly Will power that he could maintain corporeal form
If not, he might be like some kind of translucent ghost. That would take too much time for him to regain his energy
"my choice of going back to Earth was right" he thought to himself.
He did not hesitate when that time comes.
At the edge of time and space, he made a decision, his heart and soul was guided by that decision and of the many worlds he could have chosen, of all the many time space he could have picked, he was steadfast.
It was like an intuition. To break the death road in front of him, Earth have that one chance
There was many other worlds he saw in the tunnel of space and time
High energy worlds. Powerful worlds. Empty pockets of dimension scattered all over the Omniverse
