MTL - Yu-Gi-Oh!: Underworld Boss, Cancerous Creator God - Chapter 21

At 20 years old, Su He married Mr. Jiang, a business tycoon with billions to his name, proudly hailed as a business mogul. Upon learning of this, people said that she, a country bumpkin lacking background and wealth, was merely a poor doctor with a beautiful appearance, unworthy of the esteemed Jiang family head. Gradually, however, people discovered that this 'poor doctor' with 'no background' was in fact the jewel of a prestigious medical family in the capital, an expert surgeon in the medical field, an heir to a medical research institute, and a mysterious designer... Everyone knew that within Mr. Jiang's heart, there was a cherished figure. As the four-year marriage agreement neared its end, the man handed her a document, his tone gentle yet assertive: 'Sign it!' 'A divorce agreement?' Su He asked, her eyes bright with unconcealed excitement and anticipation, having longed for a divorce. The man snorted coldly, 'Just sign it!' Not long after, Mr. Jiang reneged, stating: 'Since you've given birth to my child, you'll be mine for life!'

[Once you left the mountains, you were at Eighth Grade, received recognition from a noble clan, were taught profound martial arts, but due to slow progress, were marginalized, and after a dozen years, you finally broke through to the seventh grade, but then encountered powerful foes on a mission and were killed.]

…

After countless rounds of simulations: [You encounter people, but none are a match for you. You realize that you have become invincible.]
