Li Yuxue, feeling idle, followed Li Zhongnan to the Main Fortress of Wraith King Castle. The two walked closely behind Lu Feng, entering a room at the back of the Main Fortress.
Apart from the Ghost King, no one could access the room at the back of the fortress, leaving it with a somewhat desolate atmosphere.
Lu Feng handed over a set of secret techniques to Li Zhongnan, who carefully flipped through the pages, gradually realizing that the essence of this method for refining skeletons was nothing more than crafting a controllable puppet for oneself.
After some time, it became clear—it was Puppet Technique.
However, the Ghost Clan's Puppet Technique was exceedingly profound. The secret techniques recorded here embodied the accumulated wisdom of the Ghost Clan's masters throughout the generations, methodically implemented step by step.
This was how such achievements came into being.
