Lin Wanyin traveled to a parallel world in Shanghai in 1932 and became the sickly little daughter of the Lin family.
In her previous life, she was a top actuary. In this life, she has a small problem - she is petty and particularly vindictive.
The gangster leader who bullied her family? Calculate how long it will take for him to go bankrupt.
A factory manager who underpays his wages? Calculate when his reputation will be ruined.
Until an agent of the military command came to the door: "Ms. Lin, your 'arithmetic' ability is needed by the country."
Lin Wanyin smiled and nodded, making another note in the little notebook in her heart: Use me? Okay, 30% interest.
She planned for the military commander and tried her best, but she was defeated time and time again by the greed and corruption of her colleagues.
Looking at the harvested people, she finally understood: what this country needs is not actuarial calculations, but a complete liquidation.
That night, she burned the military commission and said to the red figure in the dark: "Teach me how to plan for the people."
From then on, Shanghai lost an accountant who kept accounts, and gained an "iron abacus" that frightened the Japanese invaders and kept corrupt officials awake at night.
