Crossing the Beam, Becoming Invincible from the Very Beginning

He is the most powerful killer in modern times, codenamed "Ah Qi". He killed many people for twenty-four years, and finally died in a high-rise building. When he opened his eyes again, he became Shen Du, the lowest foot soldier at Daliang Border Gate. The grain road was attacked, the commander was killed in the battle, the organization was abolished, and there were only two people left in his place. In everyone's eyes, this is a number destined to be forgotten in the corner of the roster. But Shen Du didn't care. He carried the scimitar of the Beidi nobles and walked into Baihu's tent. "Give me a quota of twelve men. Within three months, I guarantee that this Shi Shi can eat the same number of Beidi cavalry in a frontal battle." No one, no money, no armor, no weapons? Then find it yourself. He exchanged the blood of Beidi scouts for horse meat, polished bone daggers with horse bones, and twisted tendons into a noose. He recruited taciturn veterans, fast scouts, and even a deserter who was kicked out of the camp. He broke down the killing skills in his previous life into the most basic training - silent communication, holding a dagger in the backhand, and locking the femoral artery with three knives. While the border generals were still using their lives to fill up their records, Shen Du had already climbed out of the camp wall with his "Third Shi", which he could not see in the light, on a dark and windy night. This night, he will leave seclusion. Use the blood of Beidi people to train troops. --- The killer is reborn and joins the army at the border. One person trains troops, and a thousand people make changes. The knife is not fast enough because I have never seen real death.
