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

Nero looked at the woman and waited impatiently for the money.

"Uhh… is there something else you need?" the woman asked.

"Where is the money?" Nero asked with a confused and curious look on his face.

The woman pointed her finger at Nero's guild card and said, "There is no way you can carry gold coins worth that amount, so you can use this guild card to debit the coins at any guild in the world; Whenever you want."

"And you can also directly use this in inns or big shops if they have a similar device," she added.

'Is this something like bank cards? Now that's interesting. Who came up with such an idea in this fantasy world?' Nero wondered.

"How long has this system existed?" Nero asked the woman, but the woman looked at him as though she couldn't understand Nero's question.

"Who invented these card transactions and stuff," Nero asked in simpler words.
