I, Mr. Fox, and Confucius' Library

One day after I fell asleep, I came to the library. It's just a dream, I thought. But the next night, I returned to the library. There was a knock on the door, and the uninvited guest who claimed to be God arrived. As a guest, he brought me three gifts. The first gift is brand new books that are not available outside the library. I can take these books that belong to me out of the library. The second gift is tomorrow's notes. As long as you change the records in the notes, you can rewrite tomorrow's future. The third gift is a journey to another library. After the trip, I met two friends through the library. I will introduce these two friends to you, and you will definitely like them too.
