The Wedding Princess: the Most Ruthless Taicheng Liu

[Alternate history, first perspective of the heroine] Li Siyan is the envy of all the women in Nanjing Kingdom, mainly because they envy her ability to reincarnate. Not only did he invest in the emperor's family, but he was also a twin of the current emperor. Not to mention that Nanjing was now a powerful country, unlike other countries that needed marriage in exchange for peace. Li Siyan grew up under the love of his parents and the care of his elder brother since he was a child. Even if there were rumors that he had done something wrong after his elder brother ascended the throne, his elder brother did not distance himself from him. Everyone knew that no matter whether it was people or things, as long as Li Siyan wanted it, she could get it. He didn't want the enemy country to come to sue for peace, but he asked the princess to marry him. People also say that the emperor's family is the most ruthless.
