Lin Langtian travels from the Blue Star to the Tianhuang Continent as a good-for-nothing son-in-law, awakening the system to become a saint at the very start. To save his cursed wife, Jun Yixue, he ventures alone into Yuanshi City to gamble on stones and get rich, confronts quasi-emperors head-on, charges down the ancient saintly path to subdue demon generals, and wins imperial weapon inheritances. When he gathers tens of billions of spirit stones to save his wife, he discovers that she has been possessed by the Dark Princess. In the end, he sacrifices his chaotic divine body, shares his lifespan to reverse life and death, recalls his wife's soul, repels the dark forces, and embarks on the path to break through the emperor realm and seek the upper realm.
