One Piece: Supreme Check-In System - Chapter 71: Predators on the Horizon: The Arrival of the God Knights

When I cleared the final chapter of a game that was a national failure, I became an unnamed side character in it.

A non-standard, unmeasurable, EX rank supporting character.

Kevin Reed gained enlightenment at the brink of death, as he sees the one he pledged allegiance to, and some long-time comrades betray him.

He closes his eyes one last time thinking, 'If only I had known'

Yet against all odds, he finds himself back in time in the body of the fourth prince of the royal family of a soon-to-fall Empire.

This is the story of a Knight who uses the machinations of an Empire to take his revenge on all those who betrayed him.

A man who uses the knowledge of the future to get the best out of every situation.

A man preparing for the coming of the Era of Prodigies and Disaster.

But he would have to challenge adversity if he is to bring his ambitions to fruition.

So come along on his journey filled with twists and turns, enemies and thorns.

As we see the knowledge of the future is used at its best.

But no one, not even Ezra, could've predicted just how much Chaos this single irregularity would cause.

So join us to witness Ezra, as he rises from humble beginnings, well... maybe not so humble, to becoming a peerless existence.

As he rises from the ashes to become a True Sovereign!

This is the rise...of the Infinite Sovereign!

Hundreds of years ago, Human, Celestial Clan and Demon Clan lived together on the Origin Continent. However, a great war broke out between the three races. Shan He, the leader of Human, had discovered a catalogue of methods to forge Divine Weapons. With this catalogue, Shan He led Human to defeat the other two clans and expelled them from the Origin Continent.

The peace did not last long. After the passing of Shan He, the once Glory Empire collapsed. Various forces of Human fell into a long period of wild war for the Divine Weapon Catalogue, but the catalogue was lost during the war.

The Demon Clan took advantage of the internal strife of Human. Under the lead of their new lord, Fen Tian, the Demon army invaded the Origin Continent violently.

Human soon lost a large portion of their territory. At that moment, a mysterious hero suddenly appeared on the battlefield. With a legendary Divine Weapon in hand, he severely injured Fen Tian and forced him to retreat. The united Human army chased the Demon army across the strait and to the Two Realm Plain on the Tranquil Continent.

Once again, the various forces of Human started wildly searching for the Divine Weapon Catalogue…
