If his soul awakened so early on when he was still an impressionable little boy, he might not grow up to the point of reaching this point. It was very likely that he would already have become a murderer, hated by all, maybe even the reincarnation of his wives.
As a man who had transcended past the constraints of the heavens, something like his body lacking the strength to hold his soul had long since been solved by him. It was a simple matter even to hold an Immortal God soul within a mortal's body. Or, even a soul that surpassed the Immortal God realm within such a body. After all, wasn't that what he had already done?
The reason why this incarnation of Dyon suffered from such backlash from having too strong of a soul wasn't due to the power of the soul itself, but rather because of his lack of control over the power it leaked. As a result, it had to be restrained.
