The Otherworld Armor Engineer [Sci-Fi LitRPG]

What happens when a gamer gets summoned into a world ruled by technology? Keran was mid-character-creation when the light took him. One second he's picking a class in his favorite game. The next, he's strapped to a cold metal table in another world, staring down a team of scientists who just got their first successful interdimensional summon. Every other Otherworld Lifeform who comes here eventually awakens something — claws, flames, some stolen god-tier ability.  Keran gets something no one has ever seen before: a system. A real one. Levels, stats, skills, and the power to master any technology in seconds, just by reading. He starts building photon cannons, micro-missiles, power armor forged with his own hands, not for glory. To survive. Then he meets another Otherworld Lifeform. Wait... you're not from Earth? Well. Guess I'm borrowing you, then. What to Expect: ~2,000 words per chapter Slow-burn start; early chapters focus on gear-crafting and survival, not combat-heavy action Gradual power growth, no early overpowered protagonist No harem
