Ten years ago, young Lin Wu Jiu accidentally entered the Valley of No Return in order to save his sister, and was trapped in the valley for ten years. However, a thousand years have passed in the outside world. Breaking out of the valley, Qingyang City was reduced to ruins. Martial arts flourished and sects abounded in the world, but the truth behind his disappearance actually pointed to the Tianshu Holy Land, the strongest sect in the world. During the ten years in the valley, he learned the lost skills, awakened the Holy Body of Chaos, and learned that his mother had sacrificed his life to seal the Demon Lord. Now that he has returned, his sister is imprisoned in the secret realm of the Holy Land. There is a thousand-year conspiracy hidden behind the death of his mother, and all forces covet his ancient inheritance. Rogue cultivator Zhou Butong, swordswoman Su Yuechan, and third prince Xiao Jinghuan have entered the game one after another, and the dynasty's struggle for hegemony is intertwined with the sect's game. He defeated the enemy with the Nine Revolutions of Chaos Art, grew from an avenger to a guardian step by step, and finally had a decisive battle with the Demon Lord and the traitor in front of the Valley of No Return. After a thousand years of farming, he is invincible when he comes out of the valley, but the world owes him far more than the truth.
