Du Chengfeng could confirm that it was probably not the sword's issue.
If it were Ruan Shantao himself, this Rectangular Sword might indeed have slipped up, as when it was in the old man's hands, this Bladeless Sword indeed never killed anyone — but having fallen into Du Chengfeng's hands, this sword had killed dozens at least; it was no longer some Non-Killing Sword.
Moreover, this sword had an intent to kill towards that young emperor even stronger than Du Chengfeng who wielded it.
After all, Du Chengfeng did not know the young emperor, and their connection was merely because of his cheap teacher. Coming to Jiankang to slash with this sword was no different to him than killing a fly in the kitchen — in contrast, this Rectangular Sword harbored a true, deep-seated hatred for the emperor, as its original owner had lowered his proud head due to an imperial edict.
