Chapter 431: I’ll Punish You by Making You Kneel Outside the Princess’ Residence for a Night

Gu Qingxue, who was about to enter the room, stopped in her tracks when she heard this. She turned her head and looked at Gu Chengbin with a gaze as sharp as a blade.

Gu Chengbin and Gu Qingxue's eyes met. Suddenly, because of her gaze, he subconsciously took a step back.

He had never seen Gu Qingxue look at him with such a terrifying gaze. A cold glint appeared in her eyes as she turned around and walked in Gu Chengbin's direction.

The hair on Gu Chengbin's back started to stand on end. He suddenly felt a dangerous aura emanating from Gu Qingxue. "Big sister..."

Gu Qingxue was expressionless. She raised her hand and slapped Gu Chengbin's face.

Gu Chengbin could not understand how Gu Qingxue, who looked so weak, could have such strength in her slap that it slanted half of his face.

"Since you want to claim kinship with me, then as your elder sister, I will teach you a good lesson today." Gu Qingxue smiled and looked down at Gu Chengbin.
