The humanistic epic of family algorithms with "half calculation" as the core tells the story of six generations of the Lin family (a cross-generational fusion of Shen, Jiang, Wen, and Zhou) spanning 160 years. In the era from the late Qing Dynasty to the AI era, they always adhere to the family wisdom of "calculating half points, leaving half points", leaving the incompleteness of the algorithm to the world, and leaving their complete sincerity to love and conscience. The core suspense revolves around the digital lies of the second generation Lin Shouxin. The core number group 13-415-327 is used as the suspense anchor, and the engraved abacus beads, half a silver lock, and incomplete marriage certificate are used as cross-generational tokens. The cold algorithms and numbers become a warm carrier for six generations to hide love, guard their hearts, and inherit their inheritance. The names of the six generations are naturally linked together to form the core inheritance poem "Lin Yuan Keeps the Heart" and "Sees the Returning Boat", which becomes the ultimate clue to unlocking the truth of a century. Behind the names are the times and family expectations, and they are not deliberately pieced together.
