Jiu Tou Sen was left speechless as Zhang Fei [5] brought him into the Yin-Yang Space. He had never before encountered a space detached from the universe; not even the ancient cultivators, including Guang Zhiyi, possessed such a thing.
Looking around the rooms within the space, Jiu Tou Sen spotted eight women sleeping naked inside. He quickly averted his gaze, then turned to a massive glass tube in the center of the room, which contained a vast amount of qi.
Without needing to ask, Jiu Tou Sen knew that the qi in the glass tube belonged to the eight female prisoners, but he was confused about Zhang Fei [5]'s reason for locking them up.
"They are my enemies, and I locked them in this place to harvest their yin qi." Jiu Tou Sen turned to Zhang Fei [5], who explained the identities of the eight women. "All my wives are different from me, and some of them are still weak. They always cultivate using my yang qi, but they can also use the qi in the glass tube to cultivate."
