Huanglong Zhenren is one of the Twelve Immortals of the Chan tradition in Investiture of the Gods. He resides at Magu Cave on Erxian Mountain and joins the gatherings and campaigns of the Chan immortals who support the Western Zhou cause. The available literary material does not clearly identify a disciple, so no disciple lineage is added to this foundation.
The novel states that Huanglong Zhenren travels on a crane and fights with twin swords, but does not establish fixed robe colors, age, or facial features.
He arrives in the Western Zhou camp early enough to help prepare the reed shelter used for the immortals' assembly. During the struggle with Zhao Gongming he is captured and later rescued, and in the episodes involving Lü Yue he again enters combat with his twin swords. These moments show his continuing participation in collective Chan action.
Huanglong Zhenren is the immortal of Magu Cave, a crane rider and twin-sword combatant who participates in several major Investiture campaigns. His limited individual narrative remains distinct within the Twelve Immortals.
