Run a divine bookstore, gain mighty powers from books, all my disciples are saints.

Su Xuan, an ordinary modern youth, accidentally traverses into the grand and mystical world of Westward Journey, a realm where mighty immortals, ferocious demons, and powerful buddhas govern heaven, earth, and all living beings. Amid the chaotic disputes between celestial forces and demonic tribes, he awakens a one-of-a-kind mysterious shop system, which grants him the unique ability to run a special hidden bookstore secluded deep within the remote mist-shrouded mountains. Far away from bustling mortal cities and sacred celestial palaces, this unassuming bookstore stands quietly, holding unimaginable supreme secrets within its walls. The bookstore owns countless ancient and profound scriptures that never appear in this world. Any cultivator, immortal or demon who reads the books inside can comprehend extraordinary supernatural powers, master unparalleled divine techniques, or gain top-grade magic treasures by sheer luck. Most remarkably, Su Xuan will synchronously obtain all the same abilities, treasures and insights acquired by his readers, allowing his strength to grow effortlessly without tedious cultivation or bitter trials. Word of the miraculous bookstore soon spreads across heaven and the mortal realm. Curious immortals and powerful demons flock to the remote mountains one after another to seek enlightenment from the ancient books. They gain tremendous improvements in their cultivation and strength, all reaping immense benefits from Su Xuan’s bookstore. In gratitude and awe, they respectfully honor him as an unparalleled master, holding him in the highest regard. The most earth-shaking change happens when the Monkey King stumbles upon the bookstore. After reading several ancient scriptures, his already formidable strength surges sharply to an unprecedented level. Empowered by the book’s blessings, he breaks through his original limits and rampages across the heavenly court with unmatched ferocity. Furious celestial deities march to interrogate and punish Su Xuan for causing the chaos. Yet to their utter shock and horror, they discover that the lowly bookstore owner has silently nurtured a peerless supreme saint, whose formidable strength far surpasses the entire heavenly legion, standing unshakably above all realms.
