Matthew, a 25-year-old otaku, never imagined his obsession with fantasy worlds would turn into reality—until a fatal gas leak ended his life and transported him to another world.But this wasn’t the second chance he hoped for. Born as the illegitimate son of an affair, his very existence was a stain on his family’s honor, and his father relentlessly sought to kill him.Yet Matthew, now Claude, survived, again and again, driven by an unyielding will to live.Until one day he discovered his power darkness. Feared and reviled in this world, dark mages were hunted and burned alive.Knowing his gift could become his downfall, he trained in secret under Theo, his true father.When he turned sixteen, he, his mother, Dalia, and Theo planned their escape from the small town.But their attempt was thwarted by knights and clerics from the Promised Land.Though he narrowly escaped with his life, the cost was high—his family’s safety shattered.Wounded and desperate, Matthew fled to the fabled Elysian Plains, the last hope for those like him.Just as he reached the border of the Elysian Plains at eighteen, an ambush left both him and his mother gravely injured.Collapsing on the sacred ground, he heard a voice echo in his mind:[Welcome to the Elysium of Darkness System, Lord of Calamity.][Your first quest is available!][Increase the number of dwellers in the Elysium using your seeds and blood! Spread your legacy by making demons and witches bear your children!]

Lin Sui transmigrated into the cannon fodder of a cultivation text, a cannon fodder with a human cauldron constitution, destined to be a servant. Lin Sui, unwilling to resign himself to it, seduced the Son of Heaven, but when the cut out his Dao bone and transferred it to himself, the Heavenly Law struck him down.

That Dao bone in his body became the System that restrained him, issuing the order: You must retrieve all of his soul, serve him as your master in every world, and spare no effort for him until your dying day!

Lin Su was all smiles as he agreed, but all his life, the thing he loathed most was others telling him what to do.

Therefore…

In the first world, he was an arrogant and domineering, rich and powerful Young Master, while the other person was a pitiful and humble illegitimate child.

He humiliated him by saying he was only fit to carry his shoes, and spoke words of love next to his ear when the noise of the crowd boiled over.

System: You motherxxxxxx [beep——]

Lin Sui, innocently: Aren’t I serving him as my master?

In the second world, he was a newly-promoted top talent in the entertainment industry, while the other person was a former Best Actor who went silent after an accident.

He ridiculed and suppressed him, saying deserved to make a comeback even if he was past his prime, and kissed the scars on his body at night, leaving resources behind to gracefully leave afterwards.

System: [beep——]

Lin Sui, spreading his hands: Am I still not sparing enough effort?

In the third world, he was an S-rank Alpha, while the other person was a mentally-damaged former SSS-rank Alpha.

He looked down on him, saying that useless people also deserved to get back on the battlefield, and when no one was around he said ‘since you can’t smell pheromones, then I will be your omega’, and almost lost his life giving himself to the other person.

System: …..

Lin Sui, smiling: Is my dying day enough?

Even though, in the end, he was tucked away in a golden house by the wealthy upstart, captured by the triple gold Best Actor, and completely embraced by the Imperial Marshal, he was still happy.

System, weeping bitter tears: Big brother, I’m begging you, I won’t tell you what to do any more!
