Xu Yan, a young man from a branch of the Xu family in Qingyan Town, is making slow progress in cultivation, and his father is guilty of the Chiyan Mine disaster sixteen years ago. After his family cut off his family's share of medicinal materials, Xu Yan broke into an abandoned mine in search of a missing mining boy and discovered an ancient military village buried underground. He also awakened the desolation-control monument hidden in his father's old mining lamp. In order to cure his father and clear up the old case, Xu Yan started practicing an incomplete boxing technique and entered the Beast Valley, Ancient Tombs, Sand City, Zongmen Cave, Beihuang Ancient Battlefield and Chaos Xuanhai. He became stronger in real battles one after another, and finally discovered that the mine that his father desperately sealed back then was the first formation for the upper world to extract the origin of Cangxuan Realm.
