He is the eternal enemy of the Lord of Slaughter, bringing death wherever he goes.

He is the scorn of the Great Devourer, and none of the billions of Zerg can devour him.

He is the 'WAAAGH' that the green-skinned orcs love, and he is unrivaled across the universe.

The Lord of Change wrote in a book his plans against him.

The Prince of Joy wanted to imprison him within the Sixth Ring.

He is an enemy and an ally of the Imperium of Man.

'where? Warhammer 40K? No, I want to go back to Earth! ! ! ’

After the failure of the Horus Heresy, the Chaos Legions retreated into the Eye of Terror. Among them, the Iron Warriors Legion's quickly raised troops, Peter and his brothers, broke away from the Legion and formed their own warband, the "Forged in Steel" Brothers.

"We are no longer 'hasty recruits,' no longer expendable, no longer Iron Warriors, no longer slaves to Perturabo. We are now the 'Forged in Steel' Brothers."

"And this is my battle axe, 'The Blood of Crassus.' The Blood of Crassus will have its vengeance.

"In the dark and distant future, there is only war. When the ancient Doom Slayer awakens once more by the Emperor’s will, and when the gaze of the primordial Four turns again upon the material universe, the veil between realms grows ever thinner. In this age of crumbling barriers, can the Doom Guy truly bring hope to humanity—or even the entire galaxy—as the Emperor desires?"

(Note: This is an ensemble narrative—readers who dislike this style, beware! While Doom’s storyline is absolutely present, the early chapters focus more on a sprawling cast, akin to the "Roboutian Heresy" fanworks. This is a fresh timeline, so the return of the Primarchs and major battles may not follow chronological order. That said, core lore remains intact.)

Wang Ming was teleported to the Warhammer 40k universe full of monsters and demons by the saint on the golden toilet. The system that was originally intended to bind him self-destructed after giving him an immortal body with the power of the Primarch (real immortality). Then Wang Ming started his suicidal journey in 40k with the "legacy" of the system. Among the stars of 40k, there appeared a neurotic unknown Primarch and an unknown legion speaking Chinese.

The story takes place in a different world where magic resources are strictly controlled by the mage class, and spellcasting is the exclusive privilege of the upper class. As a special group of beings, gene sorcerers possess psychic talents that allow them to cast spells without the need for magic circuits, but they are long suppressed by the mage forces.
