Yeongdo Tunnel: The Price of Passage
There exists an clandestine online forum for those who explore specific closed-off areas, 'dead spaces.' Among them, one place was repeatedly mentioned: a thread titled 'Yeongdo Tunnel – The Taking Way.' It was filled with bizarre stories. Accounts of explorers losing their sense of direction upon entering the tunnel, suffering from extreme cold, and feeling as if someone was following them. Several explorers vanished without a trace after entering, while others were found hours later at the tunnel's entrance, unable to explain the time gap, and commonly, a single personal item—a specific coin, a key, or one shoe—was missing. Local residents whispered that the tunnel was built on an ancient mountain path, rumored to have been a threshold for 'sending off' those nearing their end. It was an eerie coincidence that these incidents surged dramatically in recent months, just as a nearby walking path was abruptly closed due to 'ground instability.' No bodies were ever found.
Drawn by the ominous consistency and the clear absence of explanation, I packed professional recording and filming equipment, a thermal camera, and spare batteries, then headed to Yeongdo Tunnel. The entrance was like a crumbling concrete maw, overgrown with kudzu vines. The moment I stepped inside, the air became noticeably cold and heavy, and all sound from the outside world vanished as if by magic. The smell of damp earth, stagnant water, and an inexplicable metallic fishiness wafted into my nostrils. My powerful flashlight beam seemed to be absorbed by the ancient rock walls, dimming, and my footsteps returned strangely muffled, without echo. The tunnel sloped subtly downwards.

As I went deeper, even the echo of my footsteps faded, then vanished entirely. My own footsteps, my breathing, the faint click of my camera shutter—all sounded unnaturally close and muffled, as if the air itself was absorbing sound. I shouted loudly, but my voice failed to travel far, seeming to choke and die right in front of me. The flashlight beam struggled to pierce the darkness, as if the light itself was being sucked in. Its edges blurred, its intensity weakened, failing to properly illuminate what it should have. Shadows stretched impossibly long and deep, clinging to the periphery of my vision. A localized chill, distinct from the surrounding temperature, followed me, and I felt a subtle pressure change, like being at high altitude, a dull throb in the back of my head.
I attempted a voice test. The playback was mostly static, but beneath it, a faint, regular 'tap, tap, tap' could be heard. It sounded distant yet incredibly clear, with no echo. It was as if it resonated within the recording device, or rather, within my own head. I stopped moving, trying to locate the source of the sound. It stopped. When I moved forward again, the 'tap, tap, tap' resumed, seeming a little closer than before. The tunnel felt like it was endlessly stretching, even though I walked straight, and the entrance, now a faint dot of light, seemed no closer than when I first entered, creating an illusion of being stuck.
Growing uneasy with the deepening disorientation and impossible sounds, I decided to turn back. I switched on my compass, and its needle spun wildly before settling on an erratic direction. The GPS was completely dead. I tried to turn around and retrace my steps, but the tunnel entrance was no longer visible. Its place had been taken by an impenetrable darkness. It was as if the tunnel itself had closed behind me, or stretched out infinitely. At that moment, the air temperature plummeted painfully, bringing a cold that burned my lungs. A powerful, localized pressure enveloped me from all sides. Without a physical source, it crushed my entire body, making it impossible to breathe. I stumbled, hitting a rough stone wall. My flashlight flickered violently, then died completely, plunging me into absolute, suffocating darkness. At that instant, the regular 'tap, tap, tap' now resonated with immense volume, deep within my bones. And then, a horrific sound: a low, scraping noise, like something heavy being dragged across the stone floor. It was right behind me, yet no source could be detected.

I felt an intense, painful sensation of being 'dragged.' It was as if an invisible hand was pulling at the core of my being, threatening to tear my skin and flesh. I screamed, but the sound was immediately swallowed by the darkness. I thrashed against the wall, struggling to escape the unbearable cold and the disorienting force. I wasn't fighting a visible entity. It was a battle against a force that fundamentally distorted my reality, a force trying to 'extract' me. Seized by primal terror, I threw myself into the abyss without looking. The pulling force intensified, feeling like it was tearing my clothes and flesh, but a desperate surge of adrenaline, or perhaps a temporary gap in its power, allowed me to break free, stumbling forward, gasping for breath, clinging to the phantom sensation of my flesh being peeled from within.
Gasping, I burst out of the tunnel and collapsed onto the vine-covered approach. The ordinary outside world felt shockingly bright, loud, and alien. I was scratched and bruised, shivering to the bone with a pervasive cold. I had absolutely no memory of what had happened during the last three hours.

I checked my equipment. The video footage recorded inside the tunnel was completely corrupted. It was a chaotic mess of static and impossible visual distortions, with only brief flashes of the tunnel walls seemingly melting or stretching incomprehensibly. But the audio recorder contained a chilling snippet. After the initial static and violent struggles, a clear, perfectly isolated 'tap, tap, tap' could be heard. Not distant, but incredibly close, ending with a soft, resonant 'thump'—the sound of something being placed on the floor. The recording abruptly cut off there.
Back in my office, reviewing my notes and gear, I discovered a subtle yet specific detail. An old silver coin, inherited from my grandfather. I always kept it in my left jacket pocket, but it was gone. It had definitely been there when I entered the tunnel. I searched all my other pockets and retraced my steps, but the coin had unequivocally vanished. I recalled the forum posts: 'A single possession was missing.' The cold, the disorientation, the impossible sounds, the feeling of being torn apart. It wasn't a monster. It was a rite of passage. I had walked that path, and something had exacted a price. A payment for passage, a mark of a journey that had almost ended. The 'tap, tap, tap' seemed to continue echoing, not in my ears, but deep within my bones. I knew with chilling clarity: the tunnel was not just a physical place, but a place with a 'function,' and I had almost become one of its latest cargo.
