Yandere Warning! My Brother's Oil Bottle Has Turned Black

"Yandere + future + harem + daily life + wasteland + multiple heroines" "Husband, you are mine. From head to toe, from the inside to the outside, every drop of blood and every injury is mine." "If you dare to let other dirty things touch you, I will cut off the place where she touched you, bit by bit." ——Su Xiaoxiao "Su Xiaoqi is Su Qiqi's replacement. Su Qiqi is gone, and Su Xiaoqi will take care of Su Xiaoxiao, protect Su Xiaoxiao, and let Su Xiaoxiao survive." ——Su Xiaoqi In order to secure a future for the picked-up crazy sister Su Xiaoxiao, Su Qiqi gambled her life to take over the underworld and transport mysterious "live goods". After returning from the bloody battle, he brought back a shockingly beautiful black-haired girl with no memory, and named her Su Xiaoqi. The twisted triangular cage is thus formed. Su Xiaoxiao's smile was as bright as a flower, and she gently wiped the blood-stained knife: "Husband, there can only be one 'sister' in the family. Do you think she should die, or should I?" Su Qiqi stroked the top of her new "sister's" cold hair: "Xiao Qi, remember, your life is mine. If I die, you will be 'me'." The girl who was named the substitute raised her pure black eyes in confusion and repeated the rules of survival word for word: "Protect Xiaoxiao. Let Xiaoxiao live. This is the order given by 'Su Qiqi'." The life-and-death gamble of genetic awakening is approaching, and the stalkers of the Post-Human Alliance are quietly coming. Will this dangerous nest built with lies, blood and morbid love fall into hell together, or will more deformed flowers bloom in the ruins?
