After silently dealing with two Vulture Organization members in succession, Li Yifei finally reached the second floor. The space on the second floor was vast, with several rooms. Li Yifei sensed a Vulture Organization member armed with a gun on both the left and right, guarding against anyone breaking in from the second floor. He held a bullet casing in his hand, flicked his fingers, and the casing flew out, hitting the wall and bouncing back.
The attention of the two armed men was immediately drawn to it. Taking advantage of their turning heads, Li Yifei moved like a gecko, his body sticking to the ceiling, quickly moving past them, and slipped into a nearby room. This position was very close to the two gunmen.
The two were aiming their guns to check the source of the sound. Upon seeing it was a bullet casing, they exchanged glances and both looked towards the stairs. One of them tilted his head and whispered, "It's coming from above..."
