Ling Yutang is a killer organization that everyone in the world has heard of. They only have money you can't afford, and there's no one they can't kill. And the leader of Lingyu Hall is even more unfathomable. The world only knows that he is a young boy. His eyes always show the coldness of being isolated from the world, and his iceberg face has never shown a smile for decades. Even though he was as cold as a star, he still warmed to her and said, "I love you and will grow old together with you." Even if she didn't want to fall in love with him, she still fell in love with him and said, "I will devote my whole life to him."
A fight for medical books, a fateful entanglement. When all the dust has settled and the troubled times have returned to peace, what remains indelible are the traces carved by the years.
