Noan didn't immediately teleport to 'Tuyết Đen' City; instead, he teleported into a secret room within this cave.
This room was extraordinary, resembling an empty underground chamber, without any entrances or magical means allowing others to enter.
That's right; it appeared to be a naturally formed cavity.
However, upon appearing here, Noan realised human hands or intelligent beings had created this place.
Noan used 'Hellfire' to illuminate the area.
He saw that this was an incredibly vast room, over four meters in height and covering an area of more than 1,000 square meters.
It was an ice cellar similar to the tomb where Carlotta currently resided.
Noan looked around; it seemed this place had nothing but ice.
Even the ground had a thin layer of ice, as if water had frozen.
Noan walked across the icy surface, frowning as he gazed forward.
Ahead, there was a key placed inside a column of ice.
As he approached it, a dark shadow appeared.
