Gong Yangqi indeed hadn't set foot in Jianghu for a hundred years, yet he still kept an eye on certain matters there, but someone like Su Xin, who had reached the True Martial Realm but resorted to violence at the slightest disagreement, was rare in both his era and the present one.
Especially Su Xin's "External Heaven Flying Immortal" sword strike, the astounding sword intent behind it had utterly shaken Gong Yangqi's heart.
At the age of nearly four hundred years old, Gong Yangqi was definitely among the oldest generation of martial artists in the current Jianghu, even older than the generation of Li Boyang.
In the past, he had interacted with the ancestors of Sword God Mountain and Yi Sword Sect, and had witnessed the sword techniques of these powerhouses of Jianghu.
Although Su Xin's strength might not match theirs, his sword strike already bore the shadow of those great sword masters from days past!
