Chapter 4: The Signal Returns

The mechanical hum grew into a grinding roar as Chan yanked Felix and Jisung behind a crumbling maintenance shed. Dust rained from the corrugated roof as something massive rolled past—its silhouette a tank-like drone with a rotating dish, bristling with antennae. It stopped exactly where they’d been standing, the dish tilting as if listening. Felix pressed a hand over his mouth, heart hammering. Jisung’s eyes darted, calculating escape routes. Chan held his breath. The drone waited three heartbeats, then rumbled on, its hum fading into the hiss of the curfew siren that now wailed across the district. They stayed frozen until the siren died. Chan exhaled. “We need to get back to the hideout. Now.” They moved through alleys, avoiding patrol lights. Back in Chan’s basement, the device from the quarantine zone lay on the table—a cracked transmitter with a single blinking LED. Jisung plugged it into his decoder terminal. “The signal wasn’t a trap,” he said, frowning at the readout. “It’s a fragment. The loop recorded a real plea, but the carrier wave is two-way. Someone’s still transmitting from outside. The drone was scanning for us—for *our* response.” Felix stared at the transmitter. “Then the voice… he’s still out there.” A faint flicker of static came from the radio. Chan’s hand hovered over the dial. “If we respond, we reveal ourselves. The wardens could lock down the whole district.” “Or,” Jisung said quietly, “we finally learn what’s beyond the wall.” Felix reached past Chan and pressed the transmit button. The room hummed with silence. Then, clear as a bell, a voice crackled through—young, desperate, but alive. *“Is anyone there? Please—my name is Lee Minho. I’ve been stranded in the outer zone since the signal went dark. The walls aren’t real. The quarantine is a lie. You’re not trapped—they just want you to think you are.”* Chan’s jaw tightened. Felix gripped the radio. “We hear you. We’re in District 9. What do we do?” A pause, then Minho’s voice steadied. *“There’s a maintenance tunnel under the old water tower. It leads past the wall. I’ll meet you at sunrise. But the drones will follow if you bring any district tech. Come alone—and trust nothing that broadcasts on the curfew channel. That’s the real trap.”* The signal died. Jisung looked at the transmitter, then at Chan. “He gave us coordinates. We have maybe six hours before sunrise.” Chan ran a hand through his hair. “If we go, we leave everything. Our families, our lives.” Felix stood. “Our lives are already lies. I want to see the real sky.” Dawn broke gray and cold. The three of them walked past the water tower, through a rusted grate Jisung had pried open, down a tunnel that sloped into darkness. At the end, a silhouette waited—a boy their age, thin, with tired eyes and a crooked smile. He held out his hand. “You made it.” Chan shook first. “What happens now?” Minho turned and pointed beyond the tunnel mouth. Open fields stretched to a horizon unbroken by walls. The sun was rising gold and real. “Now we find the others. There are more of us out here than they want you to know.” Felix smiled for the first time in days. The static was gone. The signal was finally clear.
