He was an ordinary citizen,
but if Samsara also rejected him...
then, sorry, he would have to start with the organization closest to him out of the three major ones.
It seemed to be Samsara.
He was very interested in that mysterious item which the strong ones from the Mirror World had fought over back then; if the three organizations couldn't "cooperate" with him, he would have to start from the bottom up, taking over these three organizations just like he had done with Creation before.
Actually, after giving it some thought, maybe if he had started out this way, he might already have figured out what they were fighting over back then.
But at that time, he didn't even know what the three organizations were, plus with their large families and businesses, climbing up one level at a time would take a long time, and it might not be faster than accumulating a thousand cores and then joining them.
But if Samsara rejected him too, then he would only have this one path to follow.
