With Luciel's laziness, he knew that he wouldn't bother with anyone at all and wouldn't even injure them if he wasn't annoyed.
Luciel being annoyed is certainly very different from his usual lazy style, so Treyton knew that the only time Luciel would even try to hurt someone was when he was annoyed.
Sure enough, after listening to the soldier's report, Treyton learned that some people actually bothered Luciel and even continued bothering him even though he didn't pay attention to them for a long time.
In fact, after listening to what happened, Treyton thought that Luciel had already been very good as he was able to tolerate such nonsense for a longer time and didn't become impatient the first time he heard them talking about such nonsense.
It was also obvious that Luciel had already held back, as he only caused a small injury to one of the two people who had talked so much nonsense.
