The Great Wall's Algorithm: Vast

Lin Yuan, a history graduate student, developed an algorithm to decode the Great Wall in his database, only for his thesis to be rejected. Returning to his hometown ruins, his blood accidentally seeped into a Ming dynasty brick, triggering the dying memories of an old soldier defending Shanhai Pass in 1644. From then on, touching the ancient bricks allowed him to experience history firsthand: the Xifengkou broadsword troop using the wall's echo for acoustic enemy localization, the intricate game theory model behind the Zhenbeitai border markets, and the fluid dynamics wisdom of the Old Niwan ancients leveraging momentum against ice floods. The Great Wall is far more than a physical barrier; it is an ancient system still running today. However, others covet this system. Shen Zhi, a genius scholar and the theoretical core of the "Tracker" organization, vows to upgrade the Great Wall's "algorithm" into the ultimate global information firewall—where everyone he deems "impurities" will be blocked and forgotten. Amid echoes across space and time, Lin Yuan collects names forgotten by grand narratives: frontier soldiers, refugees, a water-delivering female teacher. Over three thousand years, executed and reincarnated lifetime after lifetime, he never stops carving their names into the bricks. This time, using the algorithms of the big data era, he will prove to Shen Zhi that in the algorithm of civilization, not a single person can be sacrificed. The Great Wall does not live in bricks and stone, but in human hearts. Your name is the weapon of my counterattack.
