I! the Female Supporting Character Counterattacks and Becomes the Heroine!

Yang Mingwei passed through the book and became the princess of the Sui Dynasty at the beginning, and was also bound to a "super female supporting counterattack system". It was rumored that the princess of the Sui Dynasty was uneducated and unreasonable. One day, Yang Mingwei fluently recited "On the Passage of Qin" that the Confucius asked in the school; one day, the emperor discovered that Yang Mingwei's poems could be said to have been passed down through the ages, and her calligraphy could also be a school of its own. Medical skills, mathematics... There is almost nothing she doesn't know. 1000 Years later, Yang Mingwei started the plot of the original work and became the ultimate female supporting character in the Mary Sue novel. In the original text, the heroine is a top academic who crushes the female partner in every aspect, and in the final outcome, the female partner dies tragically. The systematic Yang Mingwei decided to change this ending.
