Mysterious: The Innate Sacred Body of Destiny

A transmigrated soul finds themselves in a world where they have been transported into a book they've never read. To navigate this unfamiliar realm, they recall a video created by a fellow reader, which provides cryptic instructions for survival. The instructions cover various aspects of life, including choosing the path of an assassin, engaging in hobbies such as stargazing with a telescope, and dealing with officials who pose a significant threat. The protagonist is also advised to use certain names - Amon and Leodorus - to aid in promotion and problem-solving. As they attempt to make sense of their new reality, they must rely on these mysterious instructions to guide them through the challenges that lie ahead.
