The Möbius Dual-World Mage [Magitech | Portal | Progression | Cultivation]

180,000 Terra Credits in debt. Three hours before the Abyssal Mines claim him. On the blighted frontier of the Terra Republic, mana is scarce, metered, and never free. For those at the bottom, even the faintest magical opportunity comes with a price. Rowan Vance is one of them. During the preliminary screening for a brutal military special-recruitment exam, the strange Möbius Ring birthmark on his wrist activates, tearing open a spatial rift and throwing him into another world—a wild realm of abundant mana, natural resources, and deadly Mana-Beasts. But this new world is not a treasure chest. Its wilderness is dangerous, its magic is unfamiliar, and every gain must be earned through risk. Rowan's greatest advantage is the gap between two civilizations. With Terra's hard magic, magitech arrays, and engineering models, he begins hunting Mana-Beasts, moving resources between worlds, modernizing old spells, crafting new weapons, and turning one world's abundance into power in the other. The corporations are watching. The real military exam is still ahead. And the more Rowan exploits the gap between two worlds, the harder it becomes to remain unnoticed. What to Expect: Weak-to-Strong Progression: Advancement through risk, planning, experimentation, and resources. Analytical MC: Rowan survives through preparation, calculation, and controlled risks. Hard Magic meets Magitech: Spells, mana-pressure, magitech arrays, cybernetics, and engineering-driven magic. Two-World Logistics: Cross-world arbitrage, resource exchange, spell modernization, and civilization-gap progression. No Harem / No LitRPG System for the MC.
