The three women could only nod; it was hard for them to talk with knotted towels in their mouths.
Unless they deliberately spat the towels out, they wouldn't be able to yell or cry out.
Of course, this was Luke's idea.
It was a natural reaction for people without training, whether man or woman, to cry out when they ran into a mishap.
Luke wasn't about to risk their safety on the women's ability to control themselves; it was better to use some equipment to ensure their safety.
Seeing their nods, Luke also nodded with a smile, then turned and smoothly opened the door.
Actually, after Vice Captain Klier closed the door earlier, Luke had heard him say, "Lock the door and don't let anyone out."
His voice had been very low, but Luke had only been two meters away from him.
After the door was shut, Luke had clearly heard the sound of it being locked.
Ordinary people might not be able to hear it, but it was crystal clear to Luke.
