My Girlfriend Is a Humanoid Weapon

The world is undergoing profound changes unseen in a century. Under the undercurrent, surrounded by powerful enemies, our country launched a top secret plan - the "Xuannv Project". There are nine humanoid mechas (seven currently in service), corresponding to nine extreme human natures. They were placed in nine important areas of China, each guarding their own side, and each of them was burdened with an unspeakable past. Because Xuannv's power does not come from technology, but from human nature (No. 2 Feng Ling is "righteous", No. 3 Su Nian is "love", No. 4 Leng Yue is "anger", No. 5 Tieshan is "stable", No. 6 Weaver Girl is "fear", No. 7 Ling Shuang is "wisdom", and No. 8 Spearow is "pure") - only with the ultimate character, obsession or wish, the mecha will be effective. Some people are strong because of protection, and some people are out of control because of fear. Behind every Xuannv mecha, there is a crack; all reunions begin with a parting, and all betrayals hide the word "I'm afraid."
