沒精沒采 Spiritless And Dejected
你看那大聖落下雲頭，斜欹在山巔之上，沒精沒采，懊恨道：「這怪物十分利害。」不覺的合著眼，似睡一般。猛聽得有人叫道：「大聖，休推睡，快早上緊求救，你師父性命只在須臾間矣。」行者急睜睛跳起來看，原來是日值功曹。你看那大圣落下云头，斜欹在山巅之上，没精没采，懊恨道：「这怪物十分利害。」不觉的合着眼，似睡一般。猛听得有人叫道：「大圣，休推睡，快早上紧求救，你师父性命只在须臾间矣。」行者急睁睛跳起来看，原来是日值功曹。
逐句解 Line by line
Look at the Great Sage: he came down off his cloud and lay sprawled aslant on the mountain peak, spiritless and dejected, and said in vexation, "That monster is uncommonly dangerous."
This is the low point, and the novel marks it with a posture rather than a speech. 欹 is read qī, leaning. The dictionary makes that a slightly awkward call: 康熙字典 lists this character with one reading only, glossing it 歎美辭 — a cry of admiration — and sends the sense of tilting off to a different character built on a different root. But the man is lying slantwise across a mountaintop, so the tilting sense is plainly what is meant, and the reading follows the meaning rather than the way the character is written.
Without knowing it he had closed his eyes and seemed to be asleep.
著 is zhe, marking the eyes as closed and staying closed. The Great Sage falling asleep out of sheer dejection is not something this novel often allows him.
Of a sudden he heard someone calling, "Great Sage, do not feign sleep! Bestir yourself and go quickly for help — your master's life hangs upon a moment."
得 is the full dé in 聽得. 須臾 is the shortest stretch of time the chapter names, against the double-hour it uses elsewhere, and the closing 矣 is a literary flourish — whoever is speaking, it is not somebody plain-spoken.
Pilgrim opened his eyes with a start, sprang up and looked: it was the Merit Star on duty for the day.
日值功曹 is the Duty Officer of the Day, one of a rota of minor gods assigned to escort the pilgrims — celestial civil servants working shifts.
The chapter's lowest point, and the novel marks it physically. Monkey does not sit down to think or fly off to try again; he drops out of the sky, lies slantwise on a peak, and shuts his eyes. 你看那 — look at him — invites the audience to see a posture, not an action.
Four characters are the whole of what he says aloud, and they are an admission rather than a complaint. He has now lost his own liberty, the heavenly host, and a god's household troops, and what he produces is a flat concession that the enemy is good.
The rescue arrives as a voice before it arrives as a person, and its first words accuse him of pretending. Do not feign sleep — which assumes he is shamming, the sort of thing Monkey usually is doing and on this occasion is not.
