Hunyuan Balance: the World Is Priced by Me

I, Qi Ye, am a good-for-nothing with F-level qualifications, and I have an elder sister, Qi Shuang, who is a genius in the spirit hunting army. For nineteen years, I have lived under the halo of my sister, the ridicule of the prosecutor, and the curse of "you are dragging her down". Until that day, I was kicked into the abyss by my sister's "confidant" Lu Wen. When I was about to die, I made a contract with the devil's collateral princess - a 16-year-old girl covered in blood. It is also bound to a fate-defying system: it can deduce the future and rewrite probabilities at the cost of fate and life debt. Everyone said I wouldn't survive the first night. But I have to crawl back from the abyss and use my worst talent to overturn this man-eating chess game. My sister was unjustly imprisoned, enemies are pressing closer and closer, the alliance of the three tribes all have their own agendas, and the demons are eyeing her. But beside me, there is only a beastmaster who pretends to be trash but is hiding something secret, a half-blood witch who drives cars and has a sharp tongue, and a genius craftsman with obsessive-compulsive disorder. Whether it's a verdict in the second grade, or it's an exhaustive strategy—— I can change my life myself. If fate is unfair, tear it apart.
