The agent gathered a partial but incomplete understanding of Mengzhan by combining web search results with three fetches from alternate domains (mengzhan.vip and mengzhan.im). The primary target domain (mengzhan31.xyz) returned only React scaffold HTML with no rendered content, making it unnavigable; the agent had to work around this by pivoting to sister domains and search results to reconstruct what the platform does, who it targets, and its claimed value proposition. However, critical details like VIP pricing, monetization model, and the relationship between multiple domains remain unresolved.

• ›Fetch [13] (mengzhan.vip homepage) and [14] (mengzhan.vip/about.html) were the only content-bearing steps that returned structured HTML with actual marketing copy and platform positioning. They revealed the platform's focus on ACGN content, founding date (2018), and user count claims. Fetch [20] (mengzhan.im/manual.html) provided the most detailed breakdown of features (VIP tiers, download capability, community functions) but still lacked pricing details.
• ›The primary domain mengzhan31.xyz is essentially unmapped — fetches [1], [4], [5], [8] all returned identical React scaffold pages with no statically rendered content, only JavaScript redirects and configuration. The agent had to abandon direct site navigation and pivot to sibling domains (mengzhan.vip, mengzhan.im) discovered via web search, suggesting the site is either dynamically rendered or intentionally obfuscated.
• ›The agent's final answer relied heavily on synthesis from search results (steps [3], [10]–[12], [15]–[19]) that merely surfaced URLs but not detailed content. The agent assembled comparisons to Bilibili and Crunchyroll from general knowledge and search context, not from fetches. The VIP pricing gap was explicitly called out as unfindable — the platform mentions VIP membership but publishes no price or benefit details anywhere the agent could reach.
• ›Multiple domains (mengzhan31.xyz, mengzhan.vip, mengzhan.im, mengzhan.my, mengzhan.buzz, mengzhan.net, etc.) all point to related content but with no clear canonical URL or explanation of their relationship. This fragmentation suggests either domain migration, content distribution, or intentional obfuscation for availability/censorship resistance—none of which the agent could resolve from the pages themselves.
• ›The site publishes no machine-readable structured data (schema.org, JSON-LD) that an agent could parse for pricing, features, or positioning. All useful information had to be extracted from marketing copy on secondary domains or inferred from user manual and about-page prose.
