Cap 210: Dungeon of the Undead Part: 8
The next day we got together after eating to discuss what we're going to do today, I said we should rest today and only go to the Dungeon the next day, but Ivan said it would be better to destroy the Dungeon of the Undead as soon as possible.
He said that the miasma on floors after 50 had a very high concentration of miasma and that's why the number of monsters we faced yesterday was so large.
Ivan said that the number of monsters was so large that there could be a wave of natural monsters in that dungeon, this would be very bad since all monsters in this dungeon are Undead difficult to kill, in addition, there are many monsters that spread diseases or that can cause an epidemic.
Diana said the city of Valen would not be able to handle this wave of monsters as nearly half of the adventurers died in the last wave of monsters.
