Time Travel: My Sister Is Not a Relative

After the death of the female doctor Yuan Ning, she traveled through time and became Su Wanjun, the second daughter of the Su family. Due to an ominous person's prophecy, she was sent to her maternal ancestor's home stationed on the border to pray for her frail eldest sister. Su Wanjun took her with her when she left home. Her younger brother Su Muxuan, who was equally unpopular as her, taught him how to read, teach him the art of war, and taught him martial arts. Under Su Wanjun's careful guidance, Su Muxuan became famous at a young age and became a famous young general. Her sister was everything to Mu Xuan. Later, when the enemy attacked, Su Wanjun was arrested to protect her younger brother and her maternal cousins. Wanjun did not want the enemy to use her to threaten her grandfather and uncles to commit suicide by jumping off a cliff. She was picked up at the bottom of the cliff by the leader of the Ten Thousand Poison Sect and was tortured for three years. She worked as a medicine man for three years. Three years later, she was discovered by her younger brother and brought him to the capital. Her maternal ancestor Cheng Shengyun, the Duke of Zhenguo, took the initiative and passed Su Wanjun from the Su family to her uncle's name and entered the Cheng family tree. By accident, she married the fourth prince and became a concubine. They divorced after giving birth to a son. And when Su Muxuan knew that he and Su Wanjun were not related by blood, he silently swore in his heart that he would marry her and protect her for the rest of his life. Su Wanjun also didn't expect that her concubine was actually a prince, and after going around and around, she finally became the royal wife.
