The Big-Shot is Pampered after She Becomes the Villainness - Chapter 631 - : An Eye for an Eye

An 18-year-old poor college student tried to apply for a job as a tutor but his life almost ended as demons' meal. In his last breath, a mysterious woman gave him a strange power. When he opened his eyes he had turned into a demon with a system that would turn him into… A pervert.

Now he must lived with his dual identity as a model student named Ethan and an incubus named Damian.

A youth crept on the ground in a snowy night. Hours ago, his tendons were cut because the girl he liked plotted against him. A mysterious middle-aged man saved him, and a pair of gigantic purple pupils appeared in the sky. Under the thunders and lights, the rare Demon Pupils and Sacred Body were awakened. That was what he should have been.

However, in this world, strength was the only way to support a man to live. His adoptive father died for covering him. His true love fell into the abyss for saving him. He wanted to rise up, to take revenge, and to protect the ones he cared about.

Occasionally did a strange figure confuse him. Behind the huge demon pupils, he often saw a thirty thousand feet tall black figure. What was it? Who was that?

It was said that the ultimate bloodline of the universe was the Primal Chaos Divine Body. It was a divine existence which could break the heavens and annihilate the world in a second. However, this sort of divine body had been extinct ten thousand years ago.

Could it be that apart from the Sacred Body, there was another body in him?
