Capítulo 304: Inside the Necropolis Part 2

Upon entering the small door, the three undead were surprised to see a pitch black room that even they could not see through despite the unique characteristics of the undead. The undead are born with Dark Vision which is a superior version of Night Vision. They should be fine seeing the inside of this room but for some reason they cannot.

"The darkness here is not natural but artificial. It seems that the Arch Lich made it so that even other undead would be lost here. Luckily, we have Blanche here with us or else we would be lost upon this darkness." Noir stated.

Even though Creepysoo knows all of the vassals of his father which is the Undead King, he rarely knows about Blanche's abilities because she usually does secretarial work. All that Creepysoo knows is that Blanche is called a White Lady which is a type of undead that is said to look like a lady wearing a pure white dress that is said to be one of the benevolent type of undead.
