“I am Yang Jian. By the time you read this, I've already been dead...”A strange parchment, an eye that peeks into the darkness. This is the memoir of a person who survived.

BLURB> He was reborn by mistake. Raised with purpose. Loved by a god. Worshipped by monsters. And the galaxy doesn’t stand a fucking chance.Irvine’s soul took one wrong turn through the wheel of karma and woke up in a body grown by an intergalactic hivemind goddess with boundary issues and galaxy-sized ambition. Now he’s the golden child of a psychic swarm that feeds on control and burns whole worlds for affection.With Crystal at the helm, warriors like Kimchi, relic-weapons like Kiya, and a council of psionic horrors eager to call him king, Irvine must choose what kind of god he wants to be.Because when a hivemind learns to love......it doesn’t know when to stop.The universe will kneel—or get devoured trying.SYNOPSISIrvine didn’t ask to be reincarnated, but the cosmos had other plans. And it didn’t hand him a cheat code or a clean slate—just one random boon, selected by an uncaring divine roulette wheel.Good karma? Bad karma? Balanced as all fuck.Now he's reborn in the body of a psionically tuned alien hybrid, raised from psychic infancy by Crystal, the hivemind queen of a race so advanced they’ve abandoned individuality for shared omniscience. All except her baby boy.Irvine is the singularity inside the swarm, the first soul allowed to think, dream, and desire independently. Trained by warriors like Kimchi, advised by bio-symbiotes like Kiya, loved ferociously by hive sisters like Diane, and shadowed by powers ancient and unnamed, Irvine is both weapon and wielder, saint and sacrifice.But empires don’t run on hugs and handjobs. As Crystal expands her dominion—across star systems and sentient nebulae—Irvine must lead the charge through blood, fire, and psionic flame.His soul is still human. His body? Engineered for extinction. His heart? Not entirely his anymore.

The little handsome son-in-law passed through a world as waste material and the husband of a wealthy family. But because of his lacking aptitude, the wealthy family had driven him out. So he worked hard and found a more powerful family’s thighs to hold onto. Soon enough, he became the strongest son-in-law and husband in history.

In this world, it was impossible to practice martial arts. It was futile so he might as well take advantage of his wife’s thighs and maintain a comfortable and leisure lifestyle.

He’ll train his wife to become the strongest and best person in the world.

“Whoever dares to provoke me, let my wife kill you!”
