The final curse.

"It's nice to meet you." Heaven's eye stopped hiding and stepped forward, covered in thick black smoke that made it hard to even tell whether he was a man or a woman. The only way to distinguish his gender was through his voice and that was how everyone could be sure that he was a man.

The master of curses smirked as he mockingly spoke, "I'm afraid it's too late for you to be the hero." 

Heaven's eye did not give a response to this and since his face could not be seen, it was only natural that his reaction could also not be known. 

Without wasting another second, the master of curses started possessing the body of the demon king. 

Halfway through, he came to realize that something was wrong. 

Gritting his teeth, he threw the demon king aside. 

"What did you do?!" He roared in anger as he coughed out a mouthful of blood. 

Suddenly, a mask fell off from the demon king's face, revealing the person's real identity.
