Book 14 by Aichi Hongdoumi

In the early 1990s, after a bloody battle on the border comes to an end, Su Jing escapes death alongside her genius little one and her God of War husband. But the classified hard drive she brings back points to the Bauhinia family, at the very pinnacle of power in the capital! Once an outcast daughter of a Jiangnan embroidery family, she now wields two thousand years of mechanisms and battle formations, along with long-lost embroidery techniques. Returning to Jiangnan, she uses ruthless methods to purge the family's traitors and reclaim her position as its head, then hands its secrets over to the country. Back in the capital, she trades her tactical gear for a qipao and bankrupts her enemies with a smile at a high-society banquet. By day, she's a delicate embroiderer. Behind the scenes, she's the wealthy tycoon who controls the lifeblood of the business world. Think you can use your power to crush her? Her God of War husband sends an armored vehicle to clear the way, while her genius child hacks every account belonging to the other family: “You dared touch my mom? First check whether your whole family is bankrupt!”
