Chapter 905: Skill Advancement_1

Skill Mutation Secret Manual, such an item was something Song Jian had never encountered before; yet a golden-quality manual was clearly valuable, and the higher the quality of an item he had never seen before, the greater the probability of it being exceptional.

Song Jian's gaze fell onto the thin manual in his hands, and quickly, the attributes of the book appeared before his eyes.

"Skill Mutation Secret Manual, rare, single-use consumable, usage effect: can induce positive mutation in skills above the gold quality, enhancing skill power, improving skill effects, with a chance of upgrading the skill level! Usage requirement: a gold-quality or higher item must be consumed when using;"

"Damn, it requires the consumption of gold-quality or higher equipment to use?" Song Jian was taken aback, his face showing a look of surprise.
