Liu Qing, who lost his parents and family overnight, accidentally rescued a grassland slave Tuoba Lin, who was unexpectedly poisoned by a strange poison. Out of sympathy and his own selfishness, he sought medical treatment everywhere and met Chen Chao, an abandoned disciple of the Wandering Medicine King Valley, and they met by chance. The identities of the four people are complicated by the elegant Wang Lin. They know each other as brothers, and fall in love as a couple. They hunt for treasures, fight evildoers, and travel thousands of miles just for the one person they care about. Their love is simple and profound, and their affection is strong and transcends the world.
