Doujinshi refers to a novel that is adapted or created based on the original work, The Peerless Twins. It may contain characters, plots, or worldviews related to the original work, but it is usually reimagined, rewritten, or added with new content. The Peerless Twins was a famous wuxia novel, and its doujinshi creation was widely welcomed. Some doujinshi novels might change the villain of the original work into a positive character or combine the protagonist with the supporting characters or villains of the original work to create a new storyline. There were also some doujinshi novels that would recreate the characters in the original works, such as changing a character's personality, experience, or ending to adapt to the new storyline. Doujinshi novels were very flexible. They could allow people to relive the story of the original work or add new elements and depth to it.
