"Blissful Sky Curtain Technology was taken away by that Spirit Cultivator at the time."
Wang Jixuan asked: "Was that Spirit Cultivator named Po Suo?"
"No," He Ruli shook her head, "The first contact was with a man who called himself Hei Yao."
"Hei Yao?" Nierdamon frowned tightly.
"You know him?"
"An arch-enemy," Nierdamon said in a low voice, "He's a wanted criminal in our civilization."
He Ruli continued: "About a thousand years passed, Hei Yao brought six Spirit Cultivators, including that Po Suo you mentioned, and they took away the second batch of technology, and indeed brought thousands of souls."
"Souls?" Wang Jixuan asked, "You asked them for souls?"
He Ruli lowered her head and sighed: "Yes, Cloud City can produce various types of energy, except one kind, the power of wise life souls."
"What did you need souls for?"
"To sustain myself a bit longer and awaken the souls of the sleeping pioneers."
Wang Jixuan fell silent.
