"Building nine, where is it?"

Lu Xin felt a little dizzy as he looked at the buildings of all sizes and the windows that were still lit up in the middle of the night.

Most of the quiet and vast buildings were exposed to the light of the street lamps in the middle of the night, but there were still many that were hidden in the shadows. From a distance, it seemed like something was peeking in the darkness. Just by looking at it from a distance, one could feel an indescribable danger hidden in the buildings.

"If it really doesn't work, should I just search the buildings one by one according to the building number?"

Lu Xin quickly formulated a simple plan in his mind as he made his way forward, following the shadows of the wall.

His performance was very professional!
