Kahn drove the 'Abyss Fang: Void Rift Cutting Dagger' hard into the cobalt rock wall🪨, and the pale blue blade sank into the rock instantly. Void energy seeping through the serrations burned a ring of purple-black scorch marks on the wall🌌. In 2519, the abandoned cyber mine on the edge of the Orion Arm had been occupied by mutated mine worms for three years🚨. As a staff sergeant of the 7th Reconnaissance Battalion of the Star Marine Corps, he was the 17th soldier sent to retrieve the weapons left by the indigenous people. Military intelligence stated that this dagger was a standard issue of the mine's garrison army, 3D printed integrally from stardust-sintered titanium alloy. The serrated structure of the blade could trigger void energy during high-speed cutting to tear subspace rifts, and the three-layer hollow structure on the handle was originally used to connect to the indigenous biological neural interface, allowing the user to control the energy output of the blade through consciousness, even for short-distance teleportation🧠. Kahn reached for the neural contact on the handle, feeling a faint electric current on his fingertips, and suddenly heard a familiar communication static from deep in the mine tunnel—it was the encrypted frequency of his teammate Leia who went missing three weeks ago📡. Mixed in the static were the harsh sound of mine worms chewing through rock layers, and Leia's intermittent whispers: 'It's following the blade's energy... don't touch...'. He pulled out the dagger, the void ripples on the blade still surging, but he didn't notice that the hollow at the bottom of the handle was glowing with the same eerie light as the mine worm's eye sockets👁️, and the eerie light was slowly creeping into the vein of his wrist through the gap between his fingers holding the dagger.
