After getting stabbed to death by his girlfriend, Zane was reincarnated as Zeus— a half-demon, half-vampire. When he was one year old, he lost his parents, his castle, everything— because of the Gods and Heavens. Surviving his cruel fate, he lived among humans as one of them by hiding his true identity. 

Even though his life was nothing but suffering, he considered it as perfect; he had friends, a seemingly faithful lover, and the power to protect the world from any evil. With his limitless power, he could easily dominate the world, and neither Heaven nor Hell could stop his growth, but he chose the righteous path. However, for unknown reasons, he was betrayed and sealed to a deep slumber.

After being sealed for eternity, Zeus woke up in a mysterious dungeon to find the person who broke his seal— a half-angel beauty at death's door.

The day of his awakening, he swore that he will get his revenge and reclaim what he has lost—that is everything. Join this lonely demon on his Odyssey and watch him become the one and only— Unrivaled Demon; where no existence can equal him and no entity can defy him.

Note:- As the title of the novel says, the MC is extremely OP and knowledgeable from the start. He will have some trust issues because of what happened in the past, but no useless drama.

The Story development is slow but the story is not slow-paced. I believe character development, and building the plot is important than writing things that don't make sense. 

=====
The characters' names and relations in the novel are based on greek, Norse, Egyptian, and other mythologies, but they are not accurate as they should be. I have made some changes as per my choices, and this is just fiction.

Support the novel with power stones.

Unrivaled Demon's Odyssey

Emilia opened her eyes and found herself on a soft bed. Her body was covered with a blanket, and she could feel a magic layer around her body.

"What happened?" she asked herself.

She glanced around and saw she was in a fancy room, but she was certain that it wasn't a hotel room. The room had decorations on the wall and stuff all around the room, which implied that the room belonged to someone.

Emilia slowly sat up and grabbed her head because of the severe pain.

'I feel like my body is tearing apart from the inside.'

When Emilia looked in front of her, she saw Zeus and Faith were sleeping on the couch while hugging each other.

Emilia gritted her teeth and clenched her fists in anger.

'They look so good together. And yet… she betrayed him.'

Emilia slowly got off the bed and walked to the couch. She stood in front of the sleeping Zeus and Faith and muttered, "This is my chance to kill her."
