In the castle.
Ye Feng pushed open a large door and entered the room where the Black Dragon Immortal Emperor once resided, discovering that inside there were only a bed made of black bricks, a long table, a square stool, and a cabinet.
Besides this, there was nothing else.
He began to search, only to find a pile of dust inside the cabinet, like some items that had been left for too long, turned into weathered fragments without any research value.
A quarter of an hour later.
Ye Feng found a secret compartment on the wall around the bed. Upon opening it, he saw inside a broken ring made of black earth, looking as if it had been shattered, with mysterious patterns engraved on its surface.
"What is this?"
[Name: Identity Ring]
[Grade: None]
[Description: A black earth ring engraved with the Black Dragon Immortal Emperor's identity information, but since it's only a semi-finished product, it doesn't contain much information.]
[Remark: Symbol of Identity]
