Two Sisters in the Late Tang Dynasty: the Mad Prince's Contract Tribulation

Sisters Su Qingyan and Su Qingci, modern DINK designers, traveled through the late Tang Dynasty due to the "twin vision". They were designated by the royal family as "auspicious for the country" and were forcibly married to the twin princes Xiao Che and Xiao Jin, who were gentle on the outside but paranoid on the inside. In order to protect her sister's safety, her sister Su Qingyan made a contract marriage with the eldest prince Xiao Che to "help him win a legitimate son in exchange for lifelong sterility". However, her sister Su Qingci was placed under house arrest in the East Palace by the second prince Xiao Jin in the name of "protecting auspiciousness". As soon as the two of them got a foothold, they discovered that the contract hid a murderous intention - Xiao Che's "gentleness" was a disguise, and Xiao Jin's "protection" was a confinement. Behind it were hidden tricks such as a secret pregnancy drug, a substitute for alienation, and fake news of the death of a family member. The sisters were forced to launch the first round of counterattack.
