Ancient book restorer Tantai Mingyi discovered in Yungu Pavilion that "The Classic of Mountains and Seas" actually connected to the world of alien beasts. When the greed of reality tears the pages of the book, the other world will fall apart. Holding the "dimensional suture", he needs to use the pen as a needle to add "balance" to the story (planting trees to extinguish the fire of Bi Fang). When the conqueror coveted the passage, he knew that the bookstore was the "hub of balance" that maintained the thousands of worlds. From then on, Tantai Mingyi was no longer just a book repairman, but also a "seamer" who traveled through the pages of books, used cause and effect as a thread, and repaired the cracks in time and space. Finally, he joined hands with creatures from other worlds to build an "different-dimensional ecological observatory" to watch for harmony.
