"I didn't want to collude with the two of them..." Dongfang Fu continued muttering, thinking I was asking about what he hadn't finished saying. I smiled wryly and reminded him, "No, I was talking about absorbing yin to replenish yang."

Its cultivation effect is by no means something a single aura can match."
