Mars: Inhuman, I Am Picking up Garbage

My name is Ligus, and I have been picking up trash on Mars for seventeen years. Until I entered a laboratory by mistake, the AI ​​mistook me for its creator and forced me to give me a mecha that could crush interstellar mercenaries. I thought this was the beginning of the counterattack in the wasteland, but I discovered that I was just a genetically cloned artificial human, and my rude adoptive father, Lao Mai, actually bore the same mysterious brand as the pursuer. In order to uncover the mystery of my life experience, I flew a spacecraft out of Mars, but was told that there were six more "experimental subjects" like me.
