The "Six Void Four Harmony Divine Art" was created by Duke Chen five hundred years ago when he reached the pinnacle of his realm. It has since been continuously refined by generations of masters, adept at transforming foreign true qi within the body. However, Situ Deqing's prowess in this energy was not very pronounced; although it was extremely pure, its quantity was insufficient.
After being discovered, he charged left and right but was still devoured by Li Guanyi's inner qi.
Li Guanyi followed the operation method of this divine art and refined it.
After a full incense stick's worth of time, the hidden inner qi within Li Guanyi vanished. He leaped up, and although there was no change in the quantity of inner qi within him, he thought for a moment and walked out of the room into the courtyard.
The large stone he used for training in his courtyard was replaced daily.
Old Master Xue would smash this stone and use it as paving material.
The old man would lay these broken stones on the dirt roads of impoverished villages, turning muddy paths into stone roads, and would symbolically collect some money, so the common folk would not regard the Xue family with gratitude as if they were saints.
