逐句解 Line by line
Up on his horse the elder's heart quailed.
心驚 (xīn jīng): "the heart startled, alarmed." The single terse clause fixes Tripitaka's mortal timidity against the wild scene just described — a frailty the narrative will exploit as the chapter turns.
But the Great Sage Sun put forth his arts: brandishing the iron cudgel, he loosed a roaring howl that so terrified the wolves and vermin they tumbled and scattered, while tigers and leopards fled headlong.
佈施手段 (bù shī shǒu duàn): "to deploy [his] skills, put on a display of power" — 佈施 here is the secular "to spread forth, apply," playing wryly against its Buddhist sense of "almsgiving." The aspect-marker 著 (zhe) in 舞著鐵棒 marks the sustained brandishing. 諕得 (xià dé) "frightened [them] such that…": the graph 諕 (xià) is a vernacular variant of 嚇 "to scare," and 得 (de) here is the complement-marker particle introducing the result, not 得 (dé) "to obtain." 顛竄 (diān cuàn) "to bolt and scatter in panic."
A hinge of just two clauses, but a pointed one. The elder quails (心驚); the disciple, needing only a roar and a flourish of the cudgel, empties the mountain of its predators. The contrast is the chapter's governing irony in miniature — Wukong's power is never in doubt, only the master's ability to see it rightly. When the real threat comes disguised as a harmless woman, that same power will be turned against him as "murder."
The wordplay on 佈施 ("almsgiving" / "applying one's arts") is characteristic of the novel's texture, where Buddhist vocabulary is constantly bent to martial or comic ends. The 諕 (xià) graph recurs throughout the chapter as the demon and Bajie in turn "frighten" the timid Tripitaka; its reading is worth fixing early, since the vernacular form is easily mistaken.
