The Evil Emperor's Beloved Concubine

He is the king of the corpse world. He has cultivated for thousands of years and has an immortal body. He will last forever in the world. He will not shed tears or feel heartache. She is a modern classical dance queen. When she accidentally comes to the corpse world and meets him who is as cold as jade and ruthless, what will she do? What will happen to him? When the snowflakes in the sky are falling, when there is endless tenderness and infatuation, he will do everything in the world for her. The amethyst coffin is built for her. She has been sleeping for thousands of years, half corpse and half human body. When the green hair turns white overnight, will the memory he lost remember everything because of her heartbreak? Will he exchange all his blood for his frozen loving heart?
