Strangeness Is Coming: I Rely on Logic to Pass the Level

This year, "strange events" occurred all over the world at the same time. Lige Village, Huai'an Town, Abyss City... The isolated areas are blocked by mysterious forces. Anyone who enters them will be forced to abide by a set of incredible "rules" - they cannot answer the door knocks, cannot listen to the bells, and cannot go out at midnight. Those who violate the rules will be directly deleted. The elites of various countries were helpless and all the task forces dispatched were wiped out. Until an associate professor of mathematics named Lin Yu was involved in Lige Village. He has no powers, no system, no golden fingers. His only weapon is his brain. When others were trembling in fear, he stared at the yellow paper filled with death taboos and whispered: "These rules are propositions that can be falsified." The interval between bells is the Fibonacci sequence, the number of steps taken by the villagers is the substitution code, and behind the so-called "taboo" is a strict logical system. What others want is to live, what he wants is—— Overturn this question entirely.
