Fatty Cow was actually quite cooperative. Although part of the terrorists, he was actually a good citizen. As Zhang Ziwen had guessed, he was a sumo wrestler, not high-ranking, probably only at the entry level, respected in Japan, but turned into a terrorist. His movements and size hinted towards his rank. Zhang Ziwen had figured out his real identity and his rank judging by Fatty Cow's posture and weight.
Being a good little fat cow, he kept his head down and even leaned his ear towards Chen Yan. Highly cooperative. As he put his hand on Fatty Cow's massive shoulder, Chen Yan could measure the right angle for his move. An elegant and fast palm-cut followed, aimed to sever the spinal cord. It was a perfect lethal move. Fatty Cow collapsed like a beef mountain, head falling limply to one side, only held in place by muscle. For all his impressive build, he was helpless against this swift, precise strike. Chen Yan's handiwork was textbook perfect.
