The Abandoned Wife of a Military Family: Your disguise has been exposed again.

On their wedding night, her husband abandoned her, heading to the border. She willingly cared for his entire family, never imagining that three years later, he would return, successful and accomplished, bringing with him his mistress and illegitimate child.
“Weiwei, Yu Niang has suffered a lot with me at the border these past years. Now that she’s back, you two should get along well. Yu Niang is simple-minded and easily satisfied; she won’t compete with you for anything. Don’t use your household tricks on her!”
The man’s deep, warning voice rang in her ears like a thunderclap, jolting Yun Wei back to reality.
She stared at her husband with a strange look.
Her mother-in-law, sisters-in-law, and other relatives took turns urging her to be magnanimous and accept her husband’s woman and illegitimate child, but she resolutely proposed a divorce.
To Li Yaoting’s surprise, the wife he had discarded had become a sought-after physician by various countries, and was also having an ambiguous relationship with the current regent.
Before long, she rose to become the Empress, the mother of the nation, and Li Yaoting, including his beloved, could only grovel at her feet!
