In 80 BC, twelve-year-old Liu Bing had followed an agreement and came to an inn outside Chang'an to learn martial arts. However, he met Xu Pingjun, a young girl who was walking alone with the body of her dead mother. A precious sweat-blooded horse made them form a deep friendship. By chance, they met Yun Lang, a wandering young man, and a pair of sisters from the Western Regions who are both worlds of ice and fire. The five friends escaped from the enemy together, and they fell in love with Jinlan.
Five years later, when they met again in Chang'an, they became enemies due to family hatred and national hatred. Facing the test of friendship, love and power, where should Liu Bing go? When he came to rule the world, why did the woman with a beautiful smile next to him become so strange? In his dream, he saw the vast wilderness again, and the dew in the wind quietly wet his palms.
