When Shangguan Yushi was about to close the window, Gu Shenwei looked inside inadvertently and saw how Shangguan Ru had "taken care" of the Shadow Guard. The teenager with a knife was lying on the floor, motionless, tightly tied up, with his mouth stuffed.
Shangguan Yushi closed the window quickly, and his gaze from behind the black cloth was clearly a warning for Slave Huan that it was none of his business, but a "private matter" of the two young girls.
The four people were divided into two groups, with Shangguan Ru and Shangguan Yushi in the front, and Shangguan Fei and Gu Shenwei behind them at a distance of more than 10 steps. In the hazy moonlight, they could barely see each other.
