I Became the First Prince: Legend of Sword's Song - Chapter 1: Prologue

July, 1946. The existence of an alternate world was confirmed.

It was supposed to be a new world for mankind.

However, the enormous cost, the annihilation of the advance troops, and fierce public opposition led to the signing of a non-aggression treaty.

Mankind turned their eyes towards space.

Half a century later.

A certain company formed a team in order to explore the alternate world’s dungeon.

Five professionals and three artificial intelligences. And one reserve member.

With modern weapons and technology, the adventure was expected to be easy.

However, the ones who had arrived in the alternate world were a defective artificial intelligence and a non-professional.

Through trial and error, they lived, ate, and fought. And, they explored the dungeon.

When a terminally ill young man awakens in the world of his favorite childhood game, he realizes he isn’t the protagonist, the destined hero, or even a major side character. Instead, he has become an extra—a disowned noble barely clinging to relevance in a world where strength determines everything. Worse, his fate in the game was to die an early, meaningless death.Armed with only his knowledge of the game’s storyline and a common system that tracks his stats and skills, he is determined to survive. But mere survival isn’t enough. He remembers a hidden easter egg from a long-forgotten anime collaboration: the Mangekyō Sharingan—a power limited by game mechanics but unrestricted in reality.With Kamui as his trump card, he walks the fine line between fate and freedom, seizing power from the shadows while avoiding suspicion. As the protagonist and his allies battle against demons and unravel the game’s grand destiny, he secretly builds his own strength—manipulating events, mastering forgotten arts, and even forging ties with villainous factions.Will he remain a footnote in history, or will he carve his own legend in a world that was never meant to be his?

I’m an imperial uncle; his imperial majesty’s uncle.

Once, someone with nothing better to do took a comprehensive survey of the current dynasty, and summed up the imperial court’s three great cancers.

Wang Qin leads in corruption; the treasury is never full.

Yun Tang favours a few, forming cabals; leading to corruption in our politics.

Prince Huai plays with power, and serves as the head of a hundred poisons — thus causing instability to the throne.

When they talk about the most venomous of vipers, the wicked one who plays with power, the biggest cancer of them all, they’re talking about me: this insignificant prince, Prince Huai, Chengjun.

I can only say that I feel rather hapless in the face of these theories.

In truth, I have been ever dutiful, ever devoted, devoid of intention to monopolise power, and possess even less of a heart to covet the throne. In the entire imperial court, I dare say there is no loyal subject more loyal than I.

But, most tragically, in all the realm, the matter of my being a loyal subject is something that not many would believe.

“Beast Forge? What the hell is that?”He thought while walking out of the alley. The streets were almost empty, with only the homeless wandering around, picking up anything valuable that was dropped. He walked over to join them, still thinking he needed to do this to survive. But as he bent down, a black screen appeared in front of him, with white text displayed on it.[Beast Forge system activatedUser successfully registeredScanning user... doneUser has not awakened, cannot use Beast Forge.Analyzing for possible solutions.... doneMission: Run 10 km before 00:00Reward: Force awakeningFailure: Loss of the Beast Forge systemWill you accept this mission: YES/NO]
