inside the abandoned titanium-iron mine pit of Zeta-7 Colony🪨, Marine Recon Scout Kael clutched the "Stellar Abyss Soul-Reaver Blue Corrosion Combat Dagger" and pressed himself against the damp rock wall🔦. Forged from stardust polymer crystals via a field 3D printing system, this dagger was a standard-issue melee weapon for the colony's security forces. The hollowed triangles at the blade's tip are micro energy channels that can connect to the chest core of a soldier's powered armor, instantly emitting high-frequency cutting waves to tear through hard targets⚡. Ten minutes ago, the mutated mine worm he was tracking suddenly vanished around a tunnel corner, leaving only the squelch of slimy muscle movement and the fizz of acid mist corroding rock from deep within the pit🐛. Kael's fingers rubbed the anti-slip indentations on the handle, his knuckles white with exertion, when he suddenly felt the blue body of the dagger start to warm slightly—this was the crystal warning mechanism triggered by the acid mist secreted by the mine worm. From the shadow behind him, a pair of glowing emerald compound eyes locked onto the back of his neck through a crack in the rock wall👁️, and the dagger's channels began to glow with a faint blue light, as if responding to the unknown threat.
