Aren't You an Interesting One

The crowd hushed. No more gossips, and certainly no more sneers. Everyone was probably shocked by the demonstration and started paying meticulous attention for the rest of the lesson. But I only felt so lost and confused that I could barely follow what the master said afterward. It was his earlier words that kept echoing in my ears:

"Take demonic swords, for example. Everyone who used them knew that it was only time before they would lose control of their artifacts."

"It would only lead to chaos and deaths in the end."

Did he mean that it was inevitable for demonic swords to go berserk eventually? I searched my memory for those legends from that book I read in Bai Ye's library. The stories were all told in random order, and I hadn't paid much attention back then to which swords were mentioned and which weren't. Was it possible that each one of the swords listed in that book came with one of these tragedies?
