Eternal 教程

I checked the provided text and it only contains navigation links (previous/next links and links to related pages). Per the import rules I remove navigation and non-content elements, so there is no main content to convert into GitBook-formatted markdown.

If you want, paste the main body content of the page (headings, paragraphs, code blocks, images, FAQs, steps, etc.) and I will convert it into optimized GitBook markdown (using tabs, steppers, expandables, etc.) while preserving all links and query parameters.
