♂,
"Blood sacrifice? Fellow Daoist Wan, how can you tell?"
"Fellow Daoist Yun Bingxin found it somewhat horrifying and unbelievable. Her experience was the shallowest among us, and she knew little of the twists and turns of human hearts. She preferred to be straightforward."
"Heh heh, Fellow Daoist Yun, you don't know, do you? Blood sacrifice is blood refinement—using domineering means to seize someone else's possessions, whether treasures or energy, or even treating them as meat dumplings to activate certain grand formations that require vast amounts of energy. If this is a blood sacrifice and there are nine Spirit Transformation cultivators who possess godheads, how much power do you think it can produce? Forget ascending to the heavens—even traversing space and time might not be impossible! Of course, the conditions needed to blood-refine cultivators like us who possess godheads are also harsh. But against a legacy treasure cauldron that appears only once every five hundred years, I don't think it would be difficult!" Wan Songxiao had taken the divine-realm pillar for a cauldron. Though he only meant it figuratively, his words frightened Yun Bingxin so badly that she swallowed hard.
Back then, I had used the Blood Cloud Coffin in the netherworld to accomplish something like this, defeating a hundred enemies alone. The terror and guilt of slaughtering living beings were so great that afterward, I was unwilling to mention it no matter what. Likewise, before entering a grand formation, I would first observe whether it was a blood-refinement formation. It was equivalent to a modern tactical nuclear bomb. I would not use such a bloodthirsty weapon, but neither could I allow others to use it against me.
"This... How could this be? But the sect master of the Hidden Immortal Sect, Zu Ziyi, also has a godhead!" Yun Bingxin
