A Bizarre Journey of Seeking Truth Where One's Life Hangs in the Balance

Imaginary ancient people travel through the fictional present world. There is no system, no memory of the original body, and it is impossible to practice. A world he knew nothing about, a mirror that would kill him if he didn't charge it, and an evil spirit that would kill him if he wasn't careful. In the beginning of Skyfall, an intern protagonist who loves to read but is socially anxious tries to survive, learn and grow on a bizarre journey of seeking truth. How can you become a legitimate protagonist and enjoy the benefits without going through many tests? (It's really not slow. Counting the time, Chapter 13 is less than one day in the plot. It's the number of chapters and words that hurt the protagonist.) (Limited intelligence reasoning, psychological games, historical decryption, survival suspense)
