In the distant Yunling Mountains, the last dragon egg has been sleeping quietly for thousands of years. When the first ray of morning light penetrated the mist, Xuanzhu broke out of his shell and became the only dragon orphan in the world. He has no fire and majesty, only a soft and curious heart. The lonely Xuanzhu grew up quietly on the edge of the human village. He used his scales to sew warm nests for stray cats, and used dragon chants to wake up sleeping flowers in winter. Under the legend and prejudice that "the world no longer needs dragons", he longs to be understood, and even more eager to bring about gentle changes.
When a mysterious disaster quietly strikes, the village falls into despair. Can Xuan Zhu shake the ice of people's hearts with kindness and glimmer of light? In his loneliness and protection, the dragon's warmth is quietly lighting up the vast earth. This is a legend about a lonely dragon and human beings healing each other and growing together - under Xuan Zhu's gentle eyes, the world learns how to believe in hope again.
