Transmigrated as the Cannon Fodder Sister of a Corrupted Villain

[Fake siblings, please add to your reading list!] Jin Chen was born into a prestigious family and was the Empire's only woman in power. She commanded respect and was admired by countless people. But when she opened her eyes, she had transmigrated into a book, becoming the cannon-fodder older sister of the villainous BOSS. After he turned evil, he would skin her alive and break her bones, leaving her to die horribly. When she arrived, the original owner had just dumped a bucket of water over the villain's head. Jin Chen calmly lowered her hand and said in a grave voice: "You may have been adopted by the Jin family, but not just anyone can be my, Jin Chen's, younger brother." "I splashed you with water to wake you up." "You have three years to surpass me. Then I'll acknowledge you as my younger brother." * Jin Mo was reborn, back at age sixteen, still living with the Jin family and being bullied by that arrogant, spoiled older sister. But this time, something seemed different about Jin Chen. She dealt with the people who bullied him behind his back. She tucked him in when he fell asleep at his desk in the middle of the night. Jin Mo was intrigued. He planned to casually fulfill their three-year pact, watch her keep putting on airs, and then bring down the Jin family. But then... Jin Chen somehow came up with a pile of cutting-edge technology: hovercars, holographic games, nutrient solutions, civilian mechs... The Jin family's once-declining market value multiplied a hundredfold, and Jin Chen was hailed as "a once-in-a-millennium genius" and "a candidate for the future's richest person." Jin Mo, realizing the three-year challenge was getting harder and harder to complete: ??? [Bonus scene] Three years later. Jin Chen lists Jin Mo's transgressions: using a secret identity to start a company, tripping up the Jin family. At least he has just barely managed to catch up with her, so he qualifies as her younger brother. Jin Mo loosens his tie and breathes against her neck, smiling seductively. "But..." "Chasing after you is too hard, Big Sister. I don't want to work hard anymore." #A nation-building story powered by cutting-edge technology, with a domineering CEO heroine who makes money and stages a comeback, while raising three future powerhouses along the way# Theme: Technology makes the nation strong.
