Returning for Revenge, I Became the Eldest Prince's Favorite

[Strong women and strong men + running in both directions + revenge + pure love + redemption] Shen Tang is an expert in medicine and poisoning, but he bears a blood feud. Lin Yuanqing was born into a noble family, but was seriously ill. Shen Tang originally wanted revenge, but accidentally met Lin Yuanqing. With the benevolence of a doctor, he cured him, but she didn't expect that he would rely on him to commit her life to him. But since his blood feud has not been avenged, how can he talk about his children's affair? What? The eldest prince entered the situation and risked his life to avenge himself? Lin Yuanqing's body was weak and he was lying on the bed. Everyone expected that he would not live to see his death. He originally wanted to have no more worries about this world after completing that important event that haunted his heart. But he didn't expect to meet Shen Tang. She cured his illness, taught him what responsibility was, and gave him strength he had never had before. With her, he was full of nostalgia for this world. "You go to govern your world, and I go to practice medicine and save people. We have our own ways. When I miss you, I will come back to see you." Shen Tang said calmly. Lin Yuanqing's eyes were red and he said with great reluctance: "I support whatever you do. No matter how far you go, I will always wait for you to come back."
