Some info is missing, please help to provide it if you can.
Everything, even essential commodities like power, is scarce in Metro Center. Sometimes, strange sounds can be heard coming from deep underground. The citizens don't take them seriously, thinking it's just Valgur making the noise, but the adventurers are not convinced. They've decided to get to the bottom of this strange noise.
- The Rooms E3-E1 are randomly selected from the normal dungeons of Metro Center. The following monsters, including the Boss, may vary depending on the location.
- The boss at the end of the dungeon will drop 7~10 Purification Stones. (Maybe more or less is possible, but rare)
