Late at night, in the Cultivation Chamber of Feiquan Cave Mansion on Biyou Peak.
Jiang Ping'an waved a hand and set up the Mystic Nether Returning Array. With another wave, he precisely scattered twenty Yin Qi Beads into the array nodes, then formed a hand seal and activated the array.
Driven by true qi, the array disk blossomed with threadlike ghostly light. Twelve array flags fluttered without wind, while the gray-black yin qi contained within the twenty Yin Qi Beads was rapidly drawn out and transformed into deeper, ink-blue Mystic Yin Qi of a higher order.
The Mystic Yin Qi produced was firmly sealed within the array, not allowing even a wisp to leak out.
Before long, the Mystic Yin Qi inside the array had grown dense as fog, even forming ghostly blue ice across the ground.
Jiang Ping'an brought out the Mystic Nether Spirit Controlling Banner and summoned the Sword Envoy Spirits Xiao Duanyu and Zhang Kaifeng.
Upon sensing the dense and pure Mystic Yin Qi, Xiao Duanyu and Zhang Kaifeng instinctively revealed intense longing.
"Greetings, Master." Xiao Duanyu and Zhang Kaifeng knelt before Jiang Ping'an.
Jiang Ping'an gave a slight nod. "Go cultivate inside the array."
"Thank you, Master!!!" Xiao Duanyu and Zhang Kaifeng cried excitedly. They could not wait to fly into the array and greedily absorb the Mystic Yin Qi.
Half an hour later, Xiao Duanyu and Zhang Kaifeng had absorbed their fill of Mystic Yin Qi and could take in no more.
Jiang Ping'an waved the Mystic Nether Spirit Controlling Banner, drawing Xiao Duanyu and Zhang Kaifeng back into it so they could slowly refine the energy within the banner and turn it into cultivation.
About one-third of the Mystic Yin Qi remained inside the Mystic Nether Returning Array.
