This article tells the story of fairyland
Murong Xue, a cold-blooded senior brother with high magical power and pure innocence, caused irreversible consequences due to a certain mistake - the heroine (Nian Ling, Murong Xue's junior sister) died at his hands.
After that, he tried every means to reincarnate to retrieve Nian Ling, but every time he could only see her and others come to the end, and he could only be a "clown" who watched coldly, but every time he was reincarnated, Murong Xue would silently protect and accompany her. Later, Nian Ling regained his memory and knew everything he had done.
