Rebirth: I became rich by farming - Chapter 44 - Is Starting a Business Reliable

Kai of the Sorcerer’s Tower is one of the last mages left, barely surviving in a world ruled by creatures of the dark — where the era of mages ended, and most of the lands got contaminated with dead mana. To save his world and fulfil his master’s last wish, he put himself through a forbidden ritual, risking his soul being ripped into pieces to make his way into the past. In an era with abundant mana — an era yet to enter the Golden Era of Magic. Things go wrong, of course, as they always do, and he finds himself thousands of years before the world fell to mana contamination — in the body of a young lord, Arzan. All is not well, though, as the young lord was murdered by someone right at the cusp of a beast wave threatening the territory, while larger threats loom on the horizon. There was a lot to do for Kai to regain his former strength in this time of primitive technology, but then again, he might just be able to change that.

Entering Tokyo in the bubble era, in this strange era, the only familiar ones are Matsuda Seiko, Nakamori Akina, Kudo Shizuka…

An F-Class Hunter.

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.
