Back then, when Ling Chen discovered He Zhishen's tomb, Xu Ming told him that apart from He Zhishen, there were other people in this world who lived long lives, and one of them was his master, Su Cheng'en.
Su Cheng'en took on many disciples, but all of those disciples mysteriously disappeared in their thirties and forties. Until later, by chance, Xu Ming found many skeletons beneath his room where he lived. Not only that, the heads of those skeletons were all smashed. According to Xu Ming's guess, those skeletons must have been Su Cheng'en's former disciples. After learning that his master was a brutal murderer, Xu Ming chose to escape.
