____
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.

Disclaimer- I don't own the cover.

Unrivaled Demon's Odyssey

"Pavel is dead; I go by the name Chronos, now," he muttered with his eyes closed.

'His power is ominous, forbidding, and it defies everything— even the rules and laws of realms. His name is Chronos. And you are destined to die by his hands.'

Nero remembered what the cat in the white realm had told him.

Nero walked to Pavel and uttered, "How is Naben?"

Naben was the name of Pavel and Nero's mutual friend.

"Who knows? I don't remember the dead, and shall I be remembered after my death?"

Nero raised his brows and ordered, "Wake up, Pavel. It's me—"

Pavel hovered in the air and started attacking Nero with different types of magic. However, his eyes were still closed.

Nero dodged all of Pavel's attacks and tried to touch him, but Pavel was casting a higher level of ancient magic attacks.
