At this moment, Lu Yu was hanging outside the window on the top floor of an abandoned factory.
The muscles on his arms bulged, his fingers clenched tightly on the building's protruding edge, making his hanging position outside the window appear particularly stable.
Inside the window, thirteen armed members of the Black Cross Vanguard Army were guarding.
These thirteen members of the Black Cross Vanguard gathered together, their gazes crisscrossed, covering every dead corner in the room. No matter where one entered from, they would definitely be exposed to these men's eyes.
In such a situation, no matter which window Lu Yu appeared from, he would be attacked collectively by these thirteen members using firearms.
Since this is the top floor of an abandoned building, the range of movement is very limited, plus it is a window. If he acted rashly, he would instantly be shot into a sieve!
Therefore, Lu Yu now had to find a way to attract the attention of these thirteen people!
