Qi Xue Dan is a very low-level elixir. It's not an aid for opening the acupoints, but to open the acupoints, one must have ample qi and blood. Although Qi Xue Dan is low-level, it's just right for someone like Lu Ye who hasn't opened their acupoints.,This blow wasn't light. Liu's second son only let out a grunt before being knocked unconscious.,That was the glow of spiritual power. In other words, he was attacked by a cultivator!。
