After handling everything, Ren Bing washed off the bloodstains from his body at the water connection on the 17th floor, flushing it all down the drain as if nothing had ever happened.
The clothes he was wearing at the time were stained with blood, which he later burned.
Ren Bing was the person in charge of this construction site, concealing a dismembered corpse was not a difficult task.
