換寶找絕 The Trade Clinched
好行者,見他認了真實,又念咒語,驚動太子,把旗捲起,卻早見日光正午。小妖笑道:「妙啊!妙啊!這樣好寶貝,若不換啊,誠為不是養家的兒子。」那精細鬼交了葫蘆,伶俐蟲拿出淨瓶,一齊兒遞與行者。行者卻將假葫蘆兒遞與小妖換了。既換了寶貝,卻又幹事找絕:臍下拔一根毫毛,吹口仙氣,變作一個銅錢。叫道:「小童,你拿這個錢去買張紙來。」好行者,见他认了真实,又念咒语,惊动太子,把旗卷起,却早见日光正午。小妖笑道:「妙啊!妙啊!这样好宝贝,若不换啊,诚为不是养家的儿子。」那精细鬼交了葫芦,伶俐虫拿出净瓶,一齐儿递与行者。行者却将假葫芦儿递与小妖换了。既换了宝贝,却又干事找绝:脐下拔一根毫毛,吹口仙气,变作一个铜钱。叫道:「小童,你拿这个钱去买张纸来。」
逐句解 Line by line
Fine Pilgrim! Seeing that they took it for true, he chanted the spell again to alert the Prince, who rolled up the banner — and at once the sunlight of high noon returned.
認了真實 (rèn le zhēn shí), "had taken it for real." 把旗捲起 (bǎ qí juǎn qǐ), "rolled the banner up." Noon comes back the instant the cloth furls, and the release of the sky is as convincing as its capture.
The imps laughed: "Marvelous! Marvelous! With a treasure this fine, not to trade for it would make one no proper son of the house."
誠為不是養家的兒子 (chéng wéi bú shì yǎng jiā de ér zi), "would truly be no son who provides for his household" -- 為 read wéi, "to be," and 兒 the full noun ér. In other words: only a wastrel would pass this up. They talk themselves into it using the vocabulary of filial duty.
Fine-and-Keen handed over the gourd, Clever-Bug produced the jade vase, and together they passed them to Pilgrim.
交了葫蘆 (jiāo le hú lu), "handed the gourd over." 一齊兒 (yì qí er), "both at once," toneless 兒. Two working weapons of mass destruction, surrendered simultaneously and cheerfully.
Pilgrim in turn handed the false gourd to the imps, and the trade was done.
將假葫蘆兒 (jiāng jiǎ hú lu er) puts 將 back to work for 把: took the fake gourd and handed it across. One hair for two treasures, and not a blow struck.
Having made the exchange, he pushed the business to its limit: he plucked a hair from below his navel, blew on it a breath of immortal air, and turned it into a copper coin.
幹事找絕 (gàn shì zhǎo jué) is to push a job all the way to its limit and leave no loose end. 吹口仙氣 (chuī kǒu xiān qì), "breathed a mouthful of immortal air" -- Monkey's standard method for animating a transformed hair.
He called: "Young one, take this coin and go buy a sheet of paper."
買張紙 (mǎi zhāng zhǐ), "buy a sheet of paper." He has already won, and he is sending a victim out on an errand to fetch the stationery for the paperwork. The gesture is entirely unnecessary and entirely in character.
The moment they are convinced, Pilgrim signals, the banner furls, and noon floods back -- the release proving as persuasive as the capture. Delighted, the imps trade at once, reasoning that only a wastrel would let such a thing go, and two genuine and lethal vessels change hands for a single hair. The swindle is complete, and not a blow has been struck.
And then he cannot resist pushing it to the limit. Not content with the treasures, he conjures a coin and sends one of his victims off to buy paper for a written contract -- an absurd flourish of legal propriety laid on top of an outright fraud. The impulse is pure character. The Great Sage does not merely want to win; he wants to win with style, and to dress the theft in the forms of a fair and documented bargain.
