Stunned

Someone was already knocking on the window. Since he dared to knock on the window, it meant that he was an acquaintance.

Sure enough, Qi Yin's voice was heard, "Xue Yan."

Afraid that others would hear, Qi Yin naturally did not dare to directly address Xue Yan as the Crown Prince.

Jiang Yue gestured for Xue Yan to continue practicing his stance. In martial arts, even if it was just the basics, one should never slack. He should study and practice hard. At the same time, Jiang Yue walked to the window and opened the back window.

Then, she saw Shao Zhongxi and Qi Yin standing outside the window.

The sky had already turned dark. If it wasn't for the lights in Xue Yan's room being lit, and the windows being pushed open, they would not have been able to recognize the two adults. 

"Come in." Jiang Yue said in a low voice. Most of their family members were not asleep yet, so it was best to be low-key.
