There is a rumor in this world: Eternal night is coming, and the world is in turmoil. Only by finding the legendary person who can resolve the crisis can Ning Que, a soldier in the border town, rely on his tenacious will to overcome all obstacles and embark on the road of cultivation, becoming the guardian of the Tang Dynasty. However, under the instigation of the ambitious, the world discovered that Sang Sang, Ning Que's childhood sweetheart, was the legendary person who could respond to the omen, and wanted to put her to death. Ning Que did not want to see the kind Sang Sang get hurt, so he accompanied her to break through many obstacles, and the two wandered around the world and depended on each other for life. At this time, the ambitious intended to destroy the Tang Dynasty in one fell swoop, and assembled the coalition forces of various countries to crusade, putting the Tang Dynasty and innocent people in danger. Ning Que accepted the order in a critical moment, regardless of his personal safety, and led the army and people of the Tang Dynasty to rise up in resistance and become the guardian of the country. Ning Que and his partners gathered the strength of millions of people and the determination to defend their homeland to the death, defeated the powerful enemy, and restored peace and tranquility to the world. Ning Que found his lover Sangsang, but Sangsang had become a cold goddess at this time. Ning Que used his sincerity and practical actions to influence the goddess, and brought back the brilliance of humanity in her, and also found his Sangsang.
