New book, new book, new book, important things are said three times. The protagonist does not fight and kill in the traditional way, but fights against ghosts and monsters by analyzing, utilizing and even creating rules. This brings a strong sense of wit and freshness, which is different from most horror recovery novels on the market. The protagonist's golden finger is a "two or five boy" system, which helps him become stronger while pushing him into a pit. Looking at it now, you don't even know whether this system is a friend or an enemy. Coupled with the hard-core rules and weird stories and the epic world view, the suspense is directly hooked in the throat, and I was scratching my head after the follow-up!
