Lin Chen was once the most dazzling rising star in the international mathematics community, but he quietly retired at his peak, preferring to be the most ordinary "househusband" behind Su Wan. No one knew that he had won the highest honor in the mathematics world, and no one knew that he could use numbers as a blade to overcome all difficulties in the world. Su Wan, the risk control director of Huixin Capital, a cutting-edge private equity company, was in a critical period when the company was trying to hit the top of the industry, but it encountered a fatal bottleneck - the quantitative model of a core financial product had a fatal flaw, the data was chaotic, and the risk was out of control. If it could not be cracked within a week, the company would face huge compensation, a collapse of reputation, and even a bankruptcy crisis. Industry giants were even more eyeing, waiting for opportunities to annex. When everyone was helpless and the top management fell into despair, Su Wan unintentionally confided her predicament to her husband. Lin Chen faded away from the pyrotechnics and regained his mathematical edge. With logic and computing power that ordinary people cannot understand, he penetrated into the maze of complex financial data, dismantled the underlying loopholes in quantitative models, and reconstructed the risk measurement system. From abnormal volatility to failure of hedging strategies, from disordered capital flows to deviations in probability distributions, he used his pen as a sword and numbers as a shield to solve problems step by step. He not only saved Huixin Capital, but also single-handedly disrupted the pattern of the urban financial circle. As the problem is solved, Lin Chen's identity gradually emerges. The past glory and secrets, the covetousness and challenges in the industry, the trust and partnership between husband and wife, are intertwined into an urban financial game about wisdom, ambition, warmth and protection.
