Mu Yuming's father, Mu Qing, was a distant branch member of the Mu Family. His original life trajectory was simply to serve as a technical officer in the machinery manufacturing bureau of Tianmen City. Because he understood English and spoke the language, the Imperial Court selected him to go to Saifu to oversee weapons procurement.
At that time, just a few years after the Federal Government had ended its civil war, because the war had ended so abruptly, many private military factories that had developed during the conflict were left with a large stockpile of guns and ammunition. As the times changed rapidly and human civilization accelerated further down the path of self-destruction, these newly manufactured weapons were phased out by the domestic deployment of new generations of armaments, sadly becoming the tears of the era.
