She knocked on the door a few more times, but there was still no response.
The force of her knocks increased and attracted Ye Li and Xue Sheng's attention. The two of them walked out of their room and were stunned when they saw Xue Xi. "What's wrong?"
Xue Xi pointed at the room. "She's not opening the door."
Xue Sheng hurriedly turned to look at Ye Li. "The spare key."
Ye Li walked toward the study room. "I'll go get it. Xixi, don't panic!"
She ran to the study room and returned with the spare key. She passed it to Xue Sheng, who had Ye Li and Xue Xi hide behind him before opening the door.
The room was dark and only the window was open. The wind blew at the curtains and the moonlight shone on the roadside. There was the sound of water coming from the bathroom. Through the frosted glass, there was a faint yellow light.
Xue Sheng hurriedly stopped when he heard this.
