Cold King and Poisonous Concubine

He, a prince who is famous all over the world, loves her sister. But her sister was sent to a deep palace with red walls and green tiles. She was given to him as an apology gift by his parents. He deeply disliked her indifference and let her enter Mo Yuan, which was like a cold palace. But no one knew that at this time, she was no longer the weak woman she was before, but a soul that had come from thousands of years ago. He is good at treating poisons and can heal, with brilliant literary talent and stunning beauty. Looking back, he will be captivated. He couldn't move his eyes away, but refused to pay attention to it all. And when she regretted it, was it too late... He was her husband's brother. Although he has been seriously ill since childhood, he still has a gentle and bright smile. He had never disobeyed his brother, but because of that woman, he had a dispute with his brother for the first time. He couldn't understand why that almost luminous woman was treated like that. Love or pain, everything is just a mystery... He is a legend in the world, known as the Peerless Young Master, and his white clothes have attracted countless people. Because of his enemies' plot, he was so poisoned that he finally passed out next to her. She rescued him at will, but walked away gracefully. After searching for a long time, with only a look from her back, I found that she actually lived in a prison. And she was neither humble nor arrogant, calm as usual, her eyes were calm but seemed to have deep ripples.
