Xu Ling opened his eyes. He was now a cultivator at the Second Layer of Qi cultivation.
As expected of the highest quality living souls. Just three Living Soul Stones allowed me to successfully break through to the Second Layer of Qi cultivation. Xu Ling had killed ten zombies in the Apocalypse World and used the Blood Soul Technique to refine their living souls into ten Living Soul Stones. That was how he managed to break through using merely three of them. If I had used lower-quality Living Soul Stones, even a hundred might not have been enough for a successful breakthrough. Living Soul Stones naturally vary in quality. Even the lowest-grade Living Soul Stone was not something he could easily obtain, yet he had extravagantly used top-tier ones for his Cultivation.
