The last word wasn't finished when from upstairs, three bangs from gunshots were heard, followed by sounds of struggle. Xu Dayuan quickly ran towards Zhou Ning and the others, as the southern side was the closest entrance to the main building.
The other officers also rushed upstairs like mad. Just as Xu Dayuan reached the stairs' edge, the sound of shattering glass filled the air. A sniper rifle fell to the ground along with the glass, and after a loud noise, parts scattered everywhere.
Then two people appeared at the window. Zhou Ning squinted his eyes, Liu Yufei was choking a man by the neck. The man was covered in blood, one of his wrists handcuffed, and Liu Yufei seemed to want to lock the other cuff on her own wrist, clearly identifying this man as the hunter.
