"Well, listen carefully, I'll only say it once." Seeing him stop in his tracks and watch her intently, she proudly said, "Even if the switches on the main gate keep changing, the knob to turn the switch won't change because you always touch it. So the place for the switch must be different from other places. Therefore, once you press it down..."
"Once you press it down, you die." Dugu Chen shook his head, finding it quite amusing in his heart. However, there was a possibility for such a mechanism, but it wasn't suited for this place.
