Liu Wei punched a stone wall with all of his strength, breaking the skin on his knuckles in the process. His fist left a bloody mark, staining the clean pale green facade, but Liu Wei didn't even seem to notice. It was not the first time he punched or kicked something in the past few days, thus it wasn't all that surprising that his hand finally started to bleed.
He just needed to release his frustration somehow. It has already been five days since his opponent disappeared… And Liu Wei didn't make any progress in finding him.
Not that he hasn't tried hard enough. He has been working non-stop, without even so much as a short break to get a rest. Even when having his meals, he just grabbed something that could be eaten on the way, usually roasted pancakes, and ate it as he walked around, searching for clues.
