Soul-swapping:Imperial concubine rebirth - Chapter 2

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.

A scientific genius named Thomas Harrier was transmigrated to an imperial prince body after a car accident that took his life. He found out that he is in a world similar to our own with a timeline akin to early twentieth century. The body that he is occupying was the imperial prince of a failing empire who suddenly rose to power after a successful assassination attempt of his father. Unaware that the attack is just the beginning of what is to come. He faces many challenges throughout. Will Thomas Harrier be able to live his second life in peace while running an empire and getting it back to its former glory? Or will he succumb into a conspiracy lurking within the country's borders?

One day, a villainess came to the orphanage.“I absolutely can’t stand children!”“How can someone my age have a child? It doesn’t make sense!”“What’s so great about these little creatures that tire you out all day long…”Setting aside her dislike for children…Somehow, after she arrived, the children started gaining weight.“It’s all because of the contract, you know?”That’s what she says.While personally feeding them sweets she made herself.
