絕後之計 A Scheme to Leave No Fruit Behind
二仙童問得是實,越加毀罵。就恨得個大聖鋼牙咬響,火眼睜圓,把條金箍棒揝了又揝,忍了又忍道:「這童子只說當面打人也罷,受他些氣兒。送他個絕後計,教他大家都吃不成。」好行者,把腦後的毫毛拔了一根,吹口仙氣,叫:「變!」變做個假行者,跟定唐僧,陪著悟能、悟淨,忍受著道童嚷罵。二仙童问得是实,越加毁骂。就恨得个大圣钢牙咬响,火眼睁圆,把条金箍棒揝了又揝,忍了又忍道:「这童子只说当面打人也罢,受他些气儿。送他个绝后计,教他大家都吃不成。」好行者,把脑后的毫毛拔了一根,吹口仙气,叫:「变!」变做个假行者,跟定唐僧,陪著悟能、悟净,忍受著道童嚷骂。
逐句解 Line by line
The two immortal lads, having questioned them and got the truth, reviled them all the more.
問得是實 (wèn de shí shí) "questioned them and found it true," with the complement 得 (de). 毀罵 (huǐmà) "to abuse, heap insults."
It so galled the Great Sage that his steel teeth ground and rang and his fiery eyes glared round. He clenched and re-clenched the gold-banded cudgel, and, swallowing his temper again and again, thought: "These striplings do nothing but say I would strike a man to his face. Well and good—I shall put up with a measure of their abuse,
大聖 (Dàshèng) — "the Great Sage," Wukong's self-styled title 齊天大聖. 金箍棒 (jīngū bàng) is his gold-banded iron cudgel. 當面 (dāngmiàn) "to one's face, openly," with 當 (dāng); 氣兒 (qìr) takes the diminutive 兒 (er).
"—and deal them a scheme to leave no seed behind, so that none of them, great or small, shall ever eat of it again."
絕後計 (juéhòu jì) "a plan to cut off all posterity"—here, to destroy the tree so no fruit can ever be had again. 教 (jiào) is the causative "to make, to cause [someone to]," distinct from 教 (jiāo) "to teach." 吃不成 (chī bù chéng) "cannot manage to eat."
Good Pilgrim! He plucked a hair from the back of his head, blew on it a breath of immortal air, and cried, "Change!"
毫毛 (háomáo) — the fine body-hairs Wukong plucks and transforms, a signature of his magic. 好行者 (hǎo xíngzhě) "Good Pilgrim!" is a storyteller's formula of admiration marking a bravura feat.
It changed into a false Pilgrim, which kept close by the Tang Monk, attending Wuneng and Wujing, and bore the lads' railing in his place.
假行者 "a false Pilgrim"—the decoy left to absorb the abuse while Wukong's true self slips away. 悟能 (Wùnéng) and 悟淨 (Wùjìng) are the dharma-names of Bajie and Wujing. Both 著 here are the durative aspect-marker 著 (zhe) ("attending… bearing…").
Wukong's restraint is itself a plot device: rather than brawl with two boys, he calculates a subtler and crueller revenge—to fell the very tree, so that the loss can never be made good. The 絕後計, a "scheme to leave no heir," turns a petty quarrel over four fruits into the act that will bring the chapter's true antagonist, the Immortal Zhenyuan, down upon them.
The plucked hair transformed into a decoy is one of Wukong's stock marvels, but here it serves a precise narrative end: the false Pilgrim sits and takes the scolding while the true body escapes unseen—a doubling that lets the monkey be in two places at once, dutiful and destructive together.
