To Trick the Princess into Getting Married? You'll Be Responsible for the Consequences

[Being exchanged for marriage and getting married + Marriage first, love later + Double time travel + Palace fight + Revenge + Seizing the throne + Strong woman] "Thank God, the princess has finally arrived." The two countries of Dong Ye and Daying fought against each other for five or six years, and finally ended with the marriage of the sick third prince of Dong Ye and the princess of Daying. Um? No, the princess originally scheduled to be married was not the eldest princess? No one said anything about changing people? ———— Yang Zhaotang traveled through time and became the unlucky princess with the same name who was remarried. Forget about marrying young, the princess in her previous life died early due to unknown reasons. After receiving the memory of the princess, Yang Zhaotang shook his head helplessly, but secretly rejoiced. A fairly noble status, a sickly looking husband, a bodyguard to protect the princess, all kinds of dowries... Could it be said? This is a perfect start for Tianhu! ———— Li Yan has traveled here and pretended to be a sickly prince for more than ten years, and he is about to accept his setting. The newly married princess is not the original one... Quite pitiful. After a while: No, this lady seems to be enjoying it. After some time: No, this lady is from the same hometown! Later: When the people of the two countries mentioned the third prince and his wife, almost everyone did not praise them. "Let me see, our new emperor in Dongye should choose the third prince." "Oh, it would be great if the Grand Duke were a man... Da Ying..." "Maybe the eldest princess is really powerful? Why can't our country choose her?"
