After rebirth, I became a treacherous minister Black Moonlight

When Meng Qianqian was 15 years old, she married into the Lu family to bring good luck to the old lady.
On the wedding night, urgent news came from the border that her husband was ordered to go to the battlefield. Unfortunately, he died at the hands of the Northern Liang army half a year later.
Meng Qianqian became a widow.
Five years later, the husband who died in the war came back, with a otherworldly mute girl by his side.
Lu Lingxiao said that Wan'er was the descendant of a loyal hero. Unlike her, a business woman obsessed with money, she was a truly noble and upright woman.
Lu Lingxiao also said that Wan'er was an eagle in the sky, and a delicate flower like her was not even a fraction as good as Wan'er.
Until the mountains and rivers were shattered and the city walls collapsed, she killed thousands of soldiers with a red tasseled spear.
Lu Lingxiao then realized that he had made a mistake.
She is not a delicate flower in a deep mansion, she is the strongest west wind in Yumen Pass.
