The plagiarism of the demonic path patriarch had already attracted widespread discussion and attention. According to some criticism and accusations from the online literature world, the story plot and character setting of the demonic ancestor were plagiarized and integrated, especially in terms of character relationships and background settings. The accusations also involved copyright issues and intellectual property rights. As a fan of online literature, I believe that plagiarism and assimilation of literary works should be given a high degree of attention and criticism. Not only did plagiarism damage the author's creative rights, but it also damaged the trust and respect of readers. Originality and intellectual property rights are very important in literary creation. We should respect the creation of others and avoid plagiarism and copyright violation. Although the Devil's Ancestor was a very popular novel, its plagiarism and integration of memes had caused a lot of controversy and criticism. We should maintain an objective and rational attitude, respect different creative views and opinions, and at the same time, pay attention to protecting intellectual property rights and creativity to contribute to the development and prosperity of literary creation.
