Ji Xiao, a ghost warrior whose name has never appeared in any chain of command, tears the shackles of fate in every bloody battle. When Shen Zheng was ordered to hunt him down, he discovered that behind every secret order, there was a bloody code left by his father. What Su Yan cracked was not the encrypted file, but the countdown to the future of mankind; Zhao Xuan's silent supply line was the last conscience of the military soul; Bai Huai's inhibitor was the poison for the survival of civilization; and the military card handed over by Chen Ya was engraved with the self that should have died. They are all fighting against an invisible chain of command - and Ji Xiao is the only one who dares to tear it apart.
