The Concubine Is Often Undercover: the Concubine Mao Shang and Xiao Tang

No matter what, there was a beautiful undercover agent in front of me, but why did he have to travel to a princess with a disability and scars on her face? I thought I had met a man with a handsome face and as gentle as water, but I didn't expect that he was a wolf in sheep's clothing. After being ridiculed as a newlywed, she, Mulian, the current Princess Xuan, was thrown out of the palace in a gorgeous manner and became an abandoned concubine without even a title... The plot is fictitious, please do not imitate.
