Seo Ryung had felt it almost immediately.
The moment that they had taken a step into the left corridor, the air started to change.
It was not just cold anymore. It felt wrong.
The stone walls were seeming to close in around them, the darkness was pressing against their senses.
Then, they had heard it.
It was a voice.
Soft. Familiar.
"…Seo Ryung."
Seo Ryung's breath finally caught up.
That voice. He knew that voice.
Ji Seol-Hwa's grip was tightening on her spear. "Do not listen to it."
Heuk Cheon, however, had merely grinned.
"Oh?" Then, he tilted his head. "You are gonna have to try harder than that."
The whispers started to grow. There were more voices. Echoing. Twisting. Some of them was pleading, some mocking, some were just laughing.
Seo Ryung had gritted his teeth. He could feel it, there was a pull of something deeper.
Then…
They had finally reached the end of the corridor.
