Lin Xiaofei, an ordinary modern young man who loves fantasy, wakes up and is inexplicably transported to a mixed alien world where magic and swords are intertwined, and technology and tradition coexist. In order to find a way to return home, he had to bring the talking salted fish sauce with him, and met the cold and arrogant aristocratic girl Freya, the thick-lined thief Captain Bart, and the sharp-tongued and wise Master Allen, starting an adventure where he was constantly being tricked, tricked, surprised, and full of laughter. Along the way, they encounter alien conspiracies, misplaced royal power, out-of-control alien beasts, and hilarious misunderstandings. They work together and help each other, and finally uncover the truth about time travel, and find themselves in friendship, courage, and growth. The book consists of three volumes, compact in length, with climaxes one after another, and self-breakthrough and humor are "never lost".
