[Rebirth and revenge + scumbag sadistic novel + strong female legitimate daughter + palace fight and house fight + marriage first, love later + princess and regent + math genius + strategy + strong alliance + business] Shen Qingci was blind and blind in his previous life. Shen Qingci was poisoned by her stepmother, pushed into a well by her stepsister, and died in mysterious circumstances. When she opened her eyes again, she was reborn three days before the ceremony. In this life, she kept her eyes open and held tightly the arithmetic notes and the secret recipe for rouge left by her aunt. The dress was ruined? She showed her aunt's relics with her backhand, ruining her stepsister's reputation! Monthly charges deducted? She cleverly used arithmetic to check the accounts and made her greedy stepmother show up on the spot! The scumbag wants to step on her and reach a higher branch? She turned around and threw the evidence at the engagement party: "Mr. Gu, your scandal is known to the whole world!" Everyone thought that the orphan girl could be bullied, but she silently spread her rouge all over the country and became the owner of the "Ningxiang Pavilion" with great wealth. No one knew that Xiao Jue, the powerful and cold-hearted regent, had carved her name into their hearts. He once said: "Every account in the world can be calculated, but you are the variable that I cannot calculate accurately, and you are the only one I want to calculate for the rest of my life." When she showed all her cards, she stood on the top of power. The former enemy knelt down and begged for mercy, and the man, holding the phoenix seal, chuckled at her: "Queen, you and I share the fate of this country."
