Shen Tinglan, the daughter of the Shanghai shipping tycoon Shen family, has been obsessed with abacus since she was a child. She is more fascinated by account books than poetry collections.
With a marriage certificate, she was promised to Lu Guannan, the legendary Northland marshal who was decisive in killing and capable of stopping children from crying at night.
The whole city was watching the joke, betting on how many days this delicate abacus girl could survive under the command of the king of hell.
On the eve of the wedding, Shen Tinglan played with the small red sandalwood abacus in his hand, and the crisp sound of the abacus was particularly clear in the quiet night.
The dowry maid shivered: "Miss, what are you thinking?"
Shen Tinglan didn't even raise his head and said calmly: "Calculate the depreciation rate, risk hedging and my mental loss fee for this transaction."
After getting married, she discovered that this "deal" was far more complicated than the ledger.
This young marshal is an iron-fisted commander that everyone respects during the day, but at night he is a "technical geek" who shines at the mechanical drawings.
Shen Tinglan: "Young Marshal, the profit margin of the dock in the west of the city can be increased by three points. The prerequisite is that you have to replace the boilers of the two old ships."
Lu Guannan (looking up from a pile of gears): "Oh? Madam, do you know this? This new steam engine made in Germany, its thermal efficiency..."
As a result, the daily style of the Young Marshal's Mansion began to go astray.
While the wives of other families were discussing the latest jewelry, the young marshal's wife was discussing the cost control of arms procurement with the young marshal.
While the wives of other families were jealous in the back house, the young marshal's wife was designing an assembly line management plan for the arsenal.
