After Rebirth, the Snake Girl Snatches the Opportunity to Become the Emperor's Wife

My sister and I are the most talented twin snakes of this generation. In order to become immortals as soon as possible, the elder found two dying women to possess us. Because I was more talented, I was assigned to be the legitimate daughter of Shangshu Mansion, and was sent to the harem to absorb the dragon energy; while my sister was possessed by a medical girl and married to a general who was not a womanizer. After three years of marriage, not only did we not have sex, but we didn't even see each other a few times. My younger sister, who couldn't absorb Yang Qi, took the opportunity to visit me in the palace to seduce the emperor. The two of them not only planned to kill the general, but also killed me. When I opened my eyes again, I was back to the day of possession. Faced with my sister's entanglement, I gave up the daughter of a minister and decisively chose to be a medical girl. Accompanying a king is like accompanying a tiger. What is more useful than dragon energy is the people's heart.
