Li Zheng opened his eyes in the blood and mud, the smell of rust was still in his throat, and the snow on the execution ground was still weighing down the bodies of his wife and children. He bit into pieces the poison sac under his tongue, faked his death to hide it from the prison officer, and was dragged into the death row car. In the middle of the night, he cut off his shackles, sneaked into the armory, and used a broken blade left on the battlefield three years ago to dig out the monitoring chip in his body - a tracker implanted by the military's "Iron Law Project." He left a blood letter: "Military orders are like mountains, I accept them. But who gave them?" The footprints on the snow were wiped away by the wind, and on top of the armory in the distance, Mu Qianshan was stuffing a rusty soldier talisman into a crack in the wall with his frozen hands.
