藏訖問潔 Hidden, but Clean?
行者道：「可藏得好麼？」八戒道：「藏便藏得好，只是灒起些水來，污了衣服，有些醃臟臭氣，你休惡心。」行者笑道：「也罷，你且來受用。但不知可得個乾淨身子出門哩。」行者道：「可藏得好么？」八戒道：「藏便藏得好，只是𪷽起些水来，污了衣服，有些腌脏臭气，你休恶心。」行者笑道：「也罢，你且来受用。但不知可得个干净身子出门哩。」
逐句解 Line by line
Pilgrim said: "Have you hidden them well?"
藏 is cáng, to hide; 得 is the light de.
Eight Rules said: "As for hiding, they're hidden well enough — only some water splashed up and dirtied my clothes, and there's a filthy stench, so don't be squeamish about it."
Both instances of 藏 are cáng, the hide-verb, not the zàng of 三藏. 醃臟 is filthy, foul — and 惡心, to be disgusted, is the same word a modern Chinese speaker uses for nausea. He is telling his brother not to be squeamish while dripping.
Pilgrim laughed: "Very well — come and enjoy yourself.
也罷, "very well then" — 罷 is the verb bà, a shrug, not the light ba that softens a request.
Though I wonder whether we'll get out the door with a clean body."
The dry line that turns out to be the plot. Whether they get out of here clean is precisely the question, and the answer arrives three passages later in the form of a lychee stone. 得 in 可得 is full dé; 乾 is gān, clean; 子 is the light zi; 不 is bù before 知.
A short beat of consequences before the eating resumes. The gods are hidden well enough, at the price of a robe soaked in what was in the pit, and Bajie tells his brother not to be squeamish about a smell he is himself carrying.
Wukong's dry answer — he wonders whether they will get out of the door with a clean body — sounds like a joke about the stink and is in fact the plot. They will not.
