The day Shen Yiren put on his lawyer's robe, the courtroom was splattered with blood, and he still held the deceased's last words in his fingertips. The whole court knelt down, not because he burst into tears, but because the tampered evidence in his hand pointed directly at the heart of the powerful. He Xiaolin, the former head of the criminal investigation team of the military region, is now Shen Xianren's mortal enemy and secret agent. The two are torn between law and iron blood. One uses words as a blade to cut open the rotten flesh of the system; the other uses fists as law to crush the chains of darkness. When the lights in the Supreme Court went out, only the corners of Shen Xianren's robe were stained with blood, and He Xiaolin's gun was pointed at his uncle - and the truth had just been revealed.
