Rebirth of the Killer Queen's Counterattack

In her previous life, she made a living as a killer. She never had a name until her death, leaving only the code name: Z. In this life, she rose from the military camp, and the name "Mu Changan" accompanied her throughout her life. In her previous life, she had no relatives, no worries, and many opponents. In this life, she has relatives, friends, and him, and there are still many opponents, but she has weaknesses and armor. After being betrayed and reborn, the past is gone, but they are still entangled. "Muxia, even if you don't like my things, no one can take them away unless I nod, including you. This is the last lesson I will teach you." When Mu Changan was young, his "little talk" made a certain man who coveted her frown and be elated. He remained calm and acted step by step, causing the two people to be "entangled" for a lifetime. In his previous life, he made a living as a killer. In this life, he rose up in a military camp and changed his identity, but it was all about buying and selling human lives. However, the former is only for killing people, while the latter is mainly for saving people. In this life, he will not take the dark road but the military career.
