Originally, Chen Feiyu could not be certain that the Human-Slaying Sword would successfully pierce Fu Xing's invulnerable copper skin and iron bones. That was why he first used sword qi to strike Fu Xing's Shanzhong acupoint, waiting until the acupoint began to bleed and reveal a vulnerability before confidently unleashing the Human-Slaying Sword for a fatal blow.
To his surprise, however, the Human-Slaying Sword not only breached the defense at the Shanzhong acupoint with ease, but went straight through Fu Xing's body as though his copper skin and iron bones were as fragile as linen.
"As expected of a legacy technique of the sword immortals, a technique feared even by the Legend Powerhouse Liu Suifeng. Its power is truly terrifying. Had I known, I should have just used the Human-Slaying Sword to finish off Fu Xing from the start." Chen Feiyu shook his head, secretly annoyed that he had wasted so much time.
