That night, in the human army's basecamp roughly ten kilometers from the elven kingdom's fortress, a black bird glided silently through the darkness. From afar, it looked like an ordinary crow. But up close, its smooth metallic body and glowing red electronic eyes revealed the truth—it wasn't a real bird at all, but an advanced mechanical drone built by Ren.
Inside his car-turned-portable-workshop, Ren lay back casually, one hand holding a small remote, while his monitor displayed a live feed from the mechanical crow's point of view.
(I thought it'd be tough controlling this thing without a stable communication network. Thankfully, I installed a mini beacon earlier. With that, the signal range goes up to fifty kilometers. Lucky me.) Ren grinned slightly to himself, his fingers dancing over the controls with ease.
