The neon acid rain lashed against the impermeable barrier in Lower New Manhattan💧, dissolving the holographic scam ads into a blurry haze📺. Mercenary instructor Akai leaned against a rust-streaked training frame, his fingertips gently tracing the gleaming orange blade of this dagger🔶. The Corpse Mecha Pursuit Unit had just withdrawn from the entire block; everyone was hunting the teenage hacker who’d stolen the neural core. But Akai kept silent: the neural core his apprentice had hidden was sealed inside the hollow handle of this very dagger😱. This 3D-printed high-toughness polymer dagger contains no metal components whatsoever, so even the most advanced drug-detection security scanners can’t pick it up🔍. The pitted, crater-like pattern on the handle not only provides a secure grip but also perfectly accommodates a tiny jamming beacon; its eye-catching orange hue, in the dim underground environment, is precisely the kind of detail that no one would bother to notice🌑. In the distance, the wail of sirens grew louder as they drew nearer. Akai tossed the dagger to his apprentice, who had just emerged from a ventilation shaft, then tilted his head to signal her to slip away through the secret passage🚇—while he turned to face the searchlights. No one could say for sure whether this orange dagger was a ticket to freedom or bait for the next hunt❓
