"Blood Pool" is a novel that combines elements of city, love, suspense and career. It aims to build a fascinating literary world through sophisticated narrative and complex character relationships. The core background of the story is set in a modern city, a world where power and wealth are intertwined, and undercurrents are surging beneath the glamorous exterior. The protagonist Ben, a young man with a mysterious identity, became the son-in-law of the Su family due to family arrangements, and married Su Yao, the daughter of the Su family. However, this marriage was full of inequality and oppression from the beginning. Ben was looked down upon by the Su family and was regarded as a dispensable "outsider". The emotional depression and career dilemma brought about by the status of a son-in-law form the basis of the emotional line of the story and also pave the way for subsequent plot development. At the beginning of the story, Ben received an anonymous package, which only contained a yellowed piece of paper that read "Blood Pool Base, when the clock strikes midnight, you will know the truth!" This mysterious event completely broke his originally peaceful and humiliating life, and involved him in a huge conspiracy involving family secrets, personal life, and life and death.
