The Cursed Underground River of Baeksasil

The entrance to the underground river beneath Baeksasil Valley was elusive, taking thirty minutes to locate. Vines twisted and obstructed the hidden path, and despite the heat, the warrior felt an inexplicable chill emanating from the ominous rumors surrounding him. Standing before the limestone tunnel entrance, the air shimmered with a metallic scent. Water droplets fell from unseen cracks, creating a path that vanished into the darkness.

As he ventured deeper, the waterway grew strange. It didn’t flow like a calm stream on the ground, and even the sound of water clashing against stones defied expectation. Instead, an invisible audience seemed to mock him with eerie echoes. Drops falling from the ceiling descended lethargically, imparting a sense of uninvited intrusion into forbidden realms.

In the dim light of his flashlight, the warrior’s breath caught. His reflection in the water’s surface wavered, ensnared between two realities. Suddenly, it moved—an outstretched hand. His own hand remained still, but in a panic, he recoiled as the water shifted, transforming him and seizing his ankle. The water hugged his skin, cold and purposeful, pulling him down to the riverbed. It was a being contravening natural laws, a manifestation crafted from the whispers of countless lost wanderers.

His heart raced wildly, a desperate struggle ensued with kicks and writhing. Finally, an icy grip released him, and a tremor rippled through his bones. Crawling up the riverbank, he faced the blinding sunlight filtering through the shadowed forest, finally escaping that horrific underworld.

It was only when he reached the car that he paused. Trembling hands rummaged through his bag until he found his camera. Wet but seemingly functional, instinctively he pressed the switch, and the screen flickered on. The footage taken inside the tunnel appeared. As he watched the final scene, he gazed in disbelief: his other self standing on the water in darkness, waving goodbye.
