This is a supplement to the fourth generation of Sword and Fairy, which can be regarded as satisfying my fantasy as a fan of the fourth generation. It is said that a lot of the plots of the fourth generation are missing and have not been made, or that they were cut during the review period after being made. It seems that many maps that have been made but have not been used can be used as proof? No matter if, no guesswork. The content of this book is taken from netizens' own writings or inferences about the lost plot of The Four Immortals, and the author rewrote or expanded it. This book is made from this.
