Source of the rules: The suspense novel "Code of Taboo" written by the protagonist Lin Shen accidentally overlapped with reality. The "death rules" described in the book began to materialize in reality (such as the rule in the book "Don't look in the mirror at three o'clock in the morning". In reality, people who look in the mirror will see their reflection turning into a ghost).
Core contradiction: The rules are gradually getting out of control, changing from "fictional constraints" to "real laws", and humans are forced to abide by them. However, Lin Shen discovered that the source of the rules is the "civilization screening process" of "high-dimensional civilization" - through the rules, humans who "do not meet the standards" are eliminated, and "rule adaptors" are screened out to enter the next stage of civilization.
Goldfinger: Lin Shen has "rule editing authority" (because he is the author of the original book) and can affect the real rules by modifying the content of the novel (such as changing "Don't look in the mirror" to "Looking in the mirror to get prophecy"), but each modification will consume "rule energy" (shown as lifespan/memory in reality)
