Luo Di stared at the cellar door embedded at the center of the ground,
secured firmly by locks of different structures.
Each lock was made from different materials, possessing sealing mechanisms, such as finger-locked ones, skull locks, or those engraved with question marks, probably purchased last time from the City of Sin.
The cellar door itself also employed corner technology, though it appeared to be a thick black cellar door, both the surface plating and structural design, as well as the embedding method, were very peculiar.
Even though it was sealed so thoroughly,
an aura of fear still seeped through from below.
Even if it was only a slight seepage,
the purity and concentration of which Luo Di had never experienced before.
Since coming to the Corner, although he had seen many powerful monsters, been to many places, and experienced the fear disasters of the middle layers.
This was the first time he felt such intense fear.
