'Said the person who could not even detect an array formation,' Kyran thought.

Not bothering to argue with Dusk, Kyran walked toward the twin doors at the opposite end of the room.

Dusk did not mind Kyran's lack of response because he was already used to it. It annoyed him, to be honest, but he could not imagine the latter acting all friendly.

When Kyran arrived at the doors, he opened the door without so much of a pause that Dusk nearly broke out in cold sweats. It could not be helped because Dusk's experience thus far while roaming around the castle's underground section had not been a good one. 20% of the doors he encountered would lead him to a room full of traps, and 70% would lead into a room with a hidden array formation— like the room Kyran found him in.

If the Kyran had not come and prevented Dusk from stepping on the array formation, he would have suffered badly— worse, dead, just like Kyran said.
