Potential.

Apart from the possession of memories from his future selves, there is also the fact that he has the potential to become a god in this life, and if all goes according to his plan, he might also become an Absolute.

He is not joking about his potential to become a god. Because of him and what he assimilated that night or day when everyone in his village died, he has to ascend the undying pathway, and he has to become the god of that pathway.

Because of his existence and what he carries within him, no one else can become the god of the undying pathway. He has to die for someone else to become the god of undying.

He will be the one to look down on everyone in his pathway in the future. So his sense of superiority is well deserved. No amount of money can make someone else compare to him in terms of potential.

But he made sure to promise himself to visit all of these rich people in the future when he gains power.
