There's Something Wrong with the Heroine

[It's just a hug between two people whose lives have been replaced to keep each other warm. [You finally came, just when I was about to give up. Will you fall in love with a fictional character because of an encounter? The fifteen-year-old Ye Huai dismissed it, while the twenty-eight-year-old Ye Huai nodded crazily. From fifteen to twenty-eight, from the Ye family's only daughter and family heir to a dying homeless man on the street, Ye Huai has experienced too much. She didn't know what happened to her, but she made every wrong move at the right time, resulting in the worst ending. Even the company was taken away by her father's illegitimate daughter. Just when she was feeling discouraged, a voice sounded in her mind. Wish the system 520, whether the host is bound. The existence that claimed to be the system told her that this was not her life. Her luck had been robbed, her life had been exchanged with other people's, and the one who failed at everything and died lonely on the street was supposed to be her illegitimate daughter! The system can help her realize her wish to return to her original life. The only price is to travel to another world and help Xu Qinghuan realize her wish. Returning a wish is actually an exchange of wishes. When she helps another person realize his wish, her wish will also be realized by the system. The Xu family is the number one medicine refining family in Tianqiong Continent. When Xu Yuan was young, he fell in love with a woman in a small country and left one daughter behind. Later, she was deceived by an adulterer and died here. He only left a jade pendant for his child to prove his identity. His child was Xu Qinghuan. However, the jade pendant was taken away, and a person named Bai Xi'an took her identity. When it was time to verify her bloodline, Xu Kong of the Xu family fell in love with Bai Xi'an and willingly helped Bai Xi'an fake it. Where is Xu Qinghuan? First, her limbs were abandoned and left to fend for themselves in a small town, and then she became Bai Xi'an's mobile blood bag, because her blood can improve the success rate of refining medicine and the grade of elixirs. Like her, her life was replaced. Ye Huai agreed to the system's transaction. When she traveled to the Sky Continent, there was a person lying on the ground who had lost the will to live, exactly the same as when she was paralyzed on the street... Ye Huai walked towards the woman in front of him. She didn't know that Xu Qinghuan's wish had been taken over by many people, but they all failed. The system deceived Ye Huai. Xu Qinghuan's wish was not to take back her life, which she had achieved in her first life. She just wanted someone who loved her wholeheartedly, or who could stay with her. So she erased her memory again and again and returned to the beginning, waiting for that person to appear. Intention: You are finally here, before I give up
