Brown Bone Flame

During the past few days, Lin Yuan had already scanned through almost all of the none-auction items in the Rare Lifeform Pavilion and was only able to buy two of the inferior-class strange flames.

Following the abyss dimensional rifts' class system, the strange flames would be graded to inferior-class, medial-class, and superior-class. As for strange flames produced from Class 4 abyss dimensional rifts, they would be considered ultra-class.

As for ultra-class flames, Lin Yuan had never heard of any appearing on the market before. After all, Class 4 abyss dimensional rifts contained Class 6 demons.

As for ultra-class flames produced in Class 4 abyss dimensional rifts, only emperor-class experts were qualified to obtain them.
