In the damp cracks in the walls of Beicheng Prison, Shen Guanlan was waiting for a temporary release order. With troops approaching outside the city and power struggles within the city, she will be pushed onto the battlefield to resist the undercurrent set off by a man named Wu Jian. The person who sent her to prison was Gu Xingzhi - a man who had been in the same class with her and shared her desires and hatreds; he was also the one who pronounced the sentence and signed the sentence with his own hands.
They met at Chengjiang University many years ago. She is a statistical genius who is attractive at first glance but does not know how to express herself. He is a cool and sharp law student who believes in rules. One treats love as a proposition, and the other treats love as a variable. They achieve each other through project cooperation, but also destroy each other after a confession. Later, she traveled far, rose up, and entered the deep waters of capital and power; he climbed up step by step, taking charge of the law and order, but hidden in the order was personal grudges and possessions.
When Wu Jian's power rose from the ground to the surface, the country was infiltrated, the direction of the wind turned into a knife, and all the old accounts were opened together: the sins of the family, the debt of love, the fate that the nation would not love, and the conscience of two people repeatedly torn between "for the world" and "for themselves."
This is a long epic about how love turns into a tool of torture, about how order turns into revenge, and about how people are still reluctant to let go despite betrayal. It is written very realistically: there are no gods or Buddhas appearing, only human beings are at work; it is also very fateful: every encounter is like an echo of the previous life, and every injury is like fate collecting debts.
