The Möbius Dual-World Mage [Cyberpunk | Portal | Progression]

180,000 Terra Credits in debt. Only three days left before being condemned to the irradiated Abyssal Mines.In the cyber-wasteland of the Terra Republic, mana isn't a gift of nature—it's a resource monopolized by megacorporations. For those at the bottom, pursuing even the faintest magical opportunity is a grueling struggle. Just as Rowan Vance prepares to wager his life in a brutal Republic Military recruitment exam, the bizarre Möbius Ring birthmark on his wrist activates, pulling him into an unknown spatial rift.He wakes up in a classical world of swords and magic.Here, wild mana is abundant, and natural resources are rich. Yet, claiming them is far from easy. The untouched wilderness is fraught with primal dangers and deadly Mana-Beasts.But Rowan has one unique advantage: he can travel between the two worlds.Navigating the perilous gap between the two realms, Rowan must risk his life to acquire resources and magic. Step by step, he uses the hard magic of Terra to survive the untamed wilderness, smuggling his hard-earned gains back home to pay off his blood debt, pass the military exam, and steadily advance on his path to power.What to Expect:Weak-to-Strong Progression: Gritty, earned power-ups. No unearned handouts.Rational MC: Rowan is calm-minded, logically grounded, and makes rational choices to survive and thrive.Hard Magic meets Cyberpunk: Spells formulated through mana-pressure differentials, Magitech Arrays, and rigorous Terran models.Two-World Logistics: Cross-world arbitrage and resource smuggling.No Harem / No System: Just a man, his brain, and two colliding worlds.
