Qi Xia paused for a moment before he continued, "There shouldn't be any problems with getting 81 magical cores, and I can get someone to prepare them. The three mediums that we need are much more troublesome. It needs to be freshly cut from the corpse of a magical beast of fifth-rank or above. We would need its horns, eyes, and bones, and the beast must not have died for more than seven days. Otherwise, the items would have no effects.
Tang Nazhi then said, "You can try your luck at the Black City. The mercenaries there accept various tasks, and their targets are mostly magical beasts anyway. Furthermore, their employer usually only wanted the magical core, so the mercenaries are free to sell the leftover parts. The mercenaries who had just returned to the city should have all three of those items."
Tang Nazhi's words reminded Shen Yanxiao that it was a feasible method.
