Yi Yun followed the old man down a dark passageway. After turning the corner around a staircase, he entered a dark walkway which led underground.
There were everlasting lamps hanging on both sides of the walkway, but the light from these lamps was not warm. On the contrary, gust after gust of cold wind blew through the depths of the walkway.
The old man's pace wasn't slow, but the walkway was extremely long. After walking for almost thirty minutes, they had covered a distance of almost four kilometers.
Finally, the old man stopped and said, "Here we are."
The wind was even more chilling here. With a blow of the cold wind, the everlasting lamps flickered, dimming and brightening.
