The tunnel was not very long. After walking for slightly more than ten meters, the exit suddenly opened up to a large area!
An underground cavern of unknown proportions appeared before Bei Feng. This was an irregular cavern with a steep drop down a cylindrically shaped hole. The further down one went, the wider the hole became!
Countless tiny radiant objects filled the walls of the huge cavern. Although the amount of light they provided was inferior to even the moon's, it was enough to outline the cavern's walls. To someone like Bei Feng with heightened senses, this cavern might as well be an open field under the afternoon sun!
Bei Feng stood upon the high ground and looked downwards for as far as his vision could reach. A layer of grayish fog covered the lower reaches of the hole, causing Bei Feng to be unable to see through it.
