Once the top "Rakshasa" of the world's number one secret guard organization, the heroine Ling Shuang was betrayed by the master and organization she sacrificed her life for after her mission was successful. She narrowly escaped death and her appearance was completely destroyed. She transformed into an inconspicuous ugly girl in the world. With the skills and mind honed in hell, she started from scratch and gradually dismantled the proud power of her enemies. The highlight of the main plot is that the heroine has no golden fingers and relies entirely on her own hard power and ruthless means to carry out revenge, which is very exciting. She set up the situation with wisdom, broke it with force, and brought down the high-ranking enemies one by one. In the end, she not only killed all enemies with her hands, but also completely subverted the order of the entire old world and court, becoming the only underground king in the new era.
