Gu Yun had been listening with his ear pressed to the door. Even though the knocking was already very soft, it sounded like an explosion in his ears.
It startled him into immediately backing away two steps and rubbing his ears.
When he came back to himself, he called toward the door, "Who is it?"
The knocking outside stopped, and a lowered voice sounded. "Gu Yun? Are you in there?"
Gu Yun froze for a moment before realizing that the person outside was Sun Zhufeng.
He could hardly believe it. How had Sun Zhufeng known he was here?
He clearly remembered that when they had been looking for Shen Shuyu earlier, Sun Zhufeng had not even known the way.
But now was not the time to dwell on such details.
"It's me! Sun Zhufeng, is that you?" Gu Yun shouted excitedly through the door.
Sun Zhufeng reminded him from outside, "Keep your voice down. If you draw them over here, no one will save you."
Gu Yun immediately covered his mouth and lowered his voice. "How did you find me? Can you open the door? It's locked from the outside. I can't get it open."
"Wait."
After Sun Zhufeng said that, there was no more movement.
Gu Yun did not dare call out either. He could only press his ear to the door again and listen to the sounds outside.

Gu Yun's heart began to race. He guessed that Sun Zhufeng might have found the key to open the door.
But it also felt unbelievable. Wasn't this a little too easy?
Earlier, they had nearly gotten lost just trying to find their way around this psychiatric hospital. Sun Zhufeng in particular had seemed completely unreliable
