Myles earlier was cautious. It was inevitable, he wanted to play safe—he had learned a lot from his past mistakes. Hence, he wanted to know if the knight captain possessed an artifact.
However, what he did not expect was that the artifact required to be activated through the use of demonic energy just to activate.
In other words, so long as his shadow threads disabled the knight captain of the brand templar and his demonic energy circulation, the artifact wouldn't activate.
Furthermore, Myles was confident that only the artifacts he had to worry about. He perceived there were no more knights like veil stalkers, who kept an eye on him.
Well, there was one, but it was a Veil Stalker. The other commanders asked the Commander of the Veil Stalkers to cooperate with them in finding the primary suspect in the death of their fellow knight, including keeping a close watch on Myles.
