Chu Kuangren had once killed the Underworld God when he was the Human King.
He had also absorbed and refined his divine fragment as well.
However, the Underworld God did not know this. From his perspective, the Human King was the Human King, and Chu Kuangren was Chu Kuangren. They were two separate people.
Even in the face of death, he would never bring himself to think that the two of them were the same person.
When he heard Chu Kuangren say that he had killed him before, the Underworld God could not help but feel stunned for a moment. After that, he sneered. "Chu Kuangren, what you have killed back then was only the willpower thought form of my divine power. Bold of you to even compare it to my true form itself!
"This time, I'll show you the true power of a Venerable God."
Underworld God roared, and divine power surged out wildly, transforming into a huge dark door in the void that had the carvings of various Ashuran evil spirits.
