This sensation was similar to when he used to be able to freely take possession of others; it felt like squeezing into someone else's body.
However,
it could have been because the Solar God had been weakened too severely by him, or perhaps his spiritual power surpassed that of the Solar God. The moment that powerful will entered his body, it was mercilessly crushed and dissipated without a trace.
At this moment, Duge finally understood why the Solar God had said he would return. The Divine Soul is eternal, possessing a body and resurrecting must have been a contingency he had set aside for himself. Of course, there was also the possibility that his will would indeed gradually recover...
But regardless, the Solar God was ultimately dead. As the will of the Solar God dispersed, Duge immediately felt his soul was different than before, almost akin to when he was in the training grounds receiving the legacy of the Sea God.
