Ximen Yu

Ximen Yu is a researcher who reconstructs ancient geography from ruins and Fallen Immortal Realm fragments, uncovering politically suppressed changes in the Xuanhuang Realm.

Biography

Chapter 612

Li Fan hires Ximen Yu to calculate the modern positions of more than fifty ancient locations after reading his widely circulated geographical work. The oversized commission delights the practical scholar, but the missing sites force him to explain a more dangerous conclusion: some ancient land appears to have been removed while other regions appeared from nowhere, leaving the world larger rather than simply diminished. Ximen had already tried to publish that discovery, only for repeated Alliance censorship to reduce his manuscript to fragments. Though discouraged, he continues earning contributions through research and shifts attention toward earth-vein flow. (Chapters 612–621)

Appearance and personality

The corpus does not give Ximen Yu stable physical features. His conversations present an earnest, talkative specialist who appreciates recognition, offers refunds when an assignment cannot be completed, and balances scholarly pride with practical fee-taking. He is confident in conclusions supported by many reconstructed fragments, yet initially labels his most disruptive conjecture as bold and unproven before explaining the evidence. (Chapters 612–621)

Abilities and cultivation

Ancient-modern geographic reconstruction

Ximen correlates ancient sect ruins, directional change, reports from many Fallen Immortal Realm visitors, and modern terrain to calculate lost locations with low error. The method can distinguish likely disappearance, mist-barrier obstruction, and broader world-scale alteration, but incomplete surviving views prevent certainty for every site. It is a learned research specialty; the supplied chapters do not establish a formal cultivation realm from it. (Chapters 612–621)

Earth-vein study

After censorship undermines publication of his complete geographical manuscript, Ximen redirects research toward the flow of earth veins and offers to exchange insights with Li Fan. The later corpus confirms continued scholarly activity but does not supply a named technique or demonstrate that this research grants direct combat control over terrain. (Chapter 621; Chapters 790–1161)

Relationships

• Li Fan is Ximen Yu's major client and one of the few listeners who encourages him to explain the suppressed geographical conclusion.
• The Ten Thousand Immortals Alliance provides the contribution economy in which he works while censoring his fuller manuscript.
• Ximen Yu is distinct from Ximen Yue, the longevity-treasure contestant whose similar name appears in earlier chapters.

Items

• An Examination of Ancient and Modern Mountains and Rivers is Ximen Yu's circulated scholarly work.
• A Study of Mountains and Rivers Through the Ages is his fuller manuscript; Alliance review forces repeated cuts, and the source does not clarify custody of every surviving copy.
