Taoist Book of All Realms

Five years ago, my father died of stomach cancer, leaving behind a house full of relics and a final message: "Yuanyuan, don't trust any maps." Five years later, software engineer Lin Yuan returned to his old house to sort out his belongings and found an old mobile phone and a black notebook in his father's study. There is a mysterious system called "Legend of the Three Realms" hidden in the mobile phone, and the notebook is filled with words that do not belong to this world - they are the "operating system" of the Three Realms Walker and the legacy left to him by his father. My father is not dead. He just went beyond the real world. The moment Lin Yuan touched the notebook, a blue-white mark appeared on his palm, and a weapon spirit that had been sealed for five years broke out of the stone and announced in a lazy voice: "Welcome to the real world, traveler of the three realms." From this moment on, the world in Lin Yuan's eyes turned into three layers - the golden causal thread, the silver aura veins, and the purple human fireworks. He discovered that his colleagues around him might be infiltrators of the fantasy world, that the shoe repair stall owner downstairs might be hiding the Eye of the Three Realms, and that the Guanyi Foundation, which had been tracking his father for two years, was knocking on his door. Using programming thinking to analyze the rules of the Three Realms, and using the code warehouse to decipher the encrypted clues left by his father, Lin Yuan embarked on a road across the Three Realms to find his father. He thought the end was his father, but found that the end was a choice - when the three realms were about to collapse and the heavens collapsed, should we repair the old order or create a "new reality" that allows everything to exist?
