Great Tang: Your Highness, Shall We Strike Today?

[A socially anxious girl born into a new life as a baby + a chatty System determined to dump its Host into a crowd + adored by everyone + no CP] She becomes Li Shimin's nonexistent third daughter and binds herself to the Myriad Worlds Pinduoduo System, which lets her obtain items and skills by trading with other people. Li Qinghe goes from resisting it at first to thoroughly enjoying herself. At the Weishui Treaty, she captures Jiali alive and claims the greatest merit. At court, she repeatedly offers strategies and advice. She works to improve people's lives and fights campaigns across the land. She helps usher in the golden age of the Tang dynasty. From then on, she is like a fish in the open sea. She rises steadily from an obscure commandery princess in the Prince of Qin's residence to a princess who protects the state, and then to Prince Chen. As Li Er's princess and Prince Chen of the Tang dynasty, why shouldn't she compete for the throne? When Li Qinghe appears at Xuanwu Gate with a spear in hand, Li Shimin suddenly realizes that this daughter of his is the one who resembles him most.
