When Zhujiu was flipping through the books in the historical area of the library, he was unfortunately hit by a book on the top shelf that had not entered the bookshelf. He fell and hit his head. He closed and opened his eyes, and inexplicably came to a continent called Kyushu. There was also the book beside him that knocked him unconscious. There was also a black loach in the book. He called himself Zhuyin and told Zhujiu what he wanted to do. To return to Earth, he must complete all the strange beasts in his Book of Mountains and Seas. However, the Kyushu he traveled through was wiped out due to a world-destroying disaster, leaving only the ferocious beasts. In order to complete the Book of Mountains and Seas, they had to go to other worlds to find seeds to resurrect the strange beasts of Kyushu. Where will they go next...
