The Dao Reaches the Sky, and Knowledge Becomes a Taboo in the World of Immortality

When knowledge becomes a taboo in the world of immortality. Lin Yuan, a graduate student majoring in restoration of ancient books in the 21st century, accidentally traveled through time. He has no spiritual roots and is a complete "waste" in the world of immortality. But he brought something more powerful: modern people's knowledge system, logical thinking and civilized perspective. His golden finger is not a direct power, but a mysterious library that comes with time travel (in the early stage, only consciousness can enter). The collection of books in the library is vast, but most of them are obscure and unreadable. The unlocking condition is not cultivation, but "cognitive breakthrough" - whenever he gains insight into the essence of a phenomenon from a perspective beyond this world (such as using fluid mechanics to understand the flow of spiritual energy, using ecology to analyze the symbiosis of spiritual grass), he will unlock the corresponding books, gain knowledge, and even deduce new techniques.
