“World conquest was never part of the plan.”Yu Chen was just an ordinary programmer, slaving away at his desk, fixing bugs for a popular kingdom-building game.His life was a cycle of endless work, sleepless nights, and little appreciation. One fateful night, while struggling to fix a game-breaking bug that granted players an absurd amount of upgrade points, his exhausted heart gave out.But death wasn't the end for Yu Chen. He awoke in a world strangly familiar... he had transmigrated into the very game he had been working on, now inhabiting the body of a notorious tyrant emperor, Arkanos Bloodbane, whose empire was on the brink of destruction.Surrounded by enemies, with rebellions simmering within and war on every front, Yu Chen, now Arkanos, quickly realizes the gravity of his situation.But to his shock, he discovers that he still has access to the game's system interface—complete with the million upgrade points from the bug he had tried to fix!With his knowledge of game mechanics, strategic mind, and a wealth of upgrade points, Arkanos sets out to turn the crumbling empire into an unstoppable force. He begins by summoning legendary heroes, deploying advanced technologies never before seen in this world, and revolutionizing his military and infrastructure.As he pushes his empire to greatness, Arkanos must navigate the treacherous politics of the imperial court, fend off treacherous factions, and outmaneuver the rival nations that seek to destroy him. But with each victory, he realizes that this world is not just a game—it's his new reality. The stakes are higher, the dangers more real, and the consequences of failure more dire than ever.[Reminder, contented intended for mature audiences.]

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…
