Qi Tian cursed under his breath "Wretched Bones" as he conscientiously memorized the methods the ghost face had revealed. He then gestured for it to step back and pointed at another, ordering it to divulge everything it knew without any concealment.
Thus, none could escape Qi Tian's extraction of knowledge, and even if the methods known to the ghost faces were closely guarded secrets of certain factions, at this moment they had no choice but to obediently reveal them to Qi Tian without holding anything back.
Despite there being only nine ghost faces, in total, they disclosed over fifty methods to Qi Tian. After discounting the overlapping ones and those that were unclear, there were still twenty-three methods Qi Tian could employ and experiment with.
