不期大王知覺，被小大王等撞見。是我徒弟不知好歹，打傷兩個，眾皆喊叫，舉兵著火，他遂顧不得我，走出去了。」三個妖王呵呵大笑道：「早是驚覺，未曾走了。」叫小的們把前後門緊緊關閉，亦不諠譁。沙僧道：「閉門不諠譁，想是暗弄我師父。我們動手耶。」行者道：「說的是，快早打門。」那獃子賣弄神通，舉鈀盡力築去，把那石門築得粉碎，卻又厲聲喊罵道：「偷油的賊怪！不期大王知觉，被小大王等撞见。是我徒弟不知好歹，打伤两个，众皆喊叫，举兵着火，他遂顾不得我，走出去了。」三个妖王呵呵大笑道：「早是惊觉，未曾走了。」叫小的们把前后门紧紧关闭，亦不諠哗。沙僧道：「闭门不諠哗，想是暗弄我师父。我们动手耶。」行者道：「说的是，快早打门。」那呆子卖弄神通，举钯尽力筑去，把那石门筑得粉碎，却又厉声喊骂道：「偷油的贼怪！
逐句解 Line by line
"He did not expect Your Majesty to wake, and the lesser kings and the rest ran into him.
知覺 is to become aware, to come to notice — used here of waking up and grasping what is going on in the same breath. The demon king did both at once, which is exactly what happened.
It was my disciple, not knowing what was good for him, who wounded two of them; and when everyone shouted and weapons and fires were raised, he could not see to me after all, and went out."
不知好歹 — not knowing good from bad — is a scolding phrase a parent uses, and Tripitaka is using it about the disciple who just risked everything for him, to the people who chained him up. 舉兵著火 has 著 as the achieved zháo: fires catching, not fires being tended. And 顧不得 comes back for the third time in twenty lines — the phrase the whole rescue turns on, repeated until it sticks.
The three demon kings laughed aloud and said, "It is as well we woke — he did not get away with it."
呵呵大笑 is the standard laugh of a villain in this novel, and it is written as a sound. 早是 means "it is fortunate that" — the demons are congratulating themselves on a light sleeper, which is exactly what saved them.
They ordered the little ones to shut the front and back doors fast, and to make no noise at all.
諠譁 is a clamour of voices — the word for a room full of people all talking. Ordering it stopped is a strange, deliberate thing for a demon to do, and the next line is somebody noticing.
Sha Monk said, "Doors shut and no noise — I think they mean to do something to our master in secret.
This is Sha Monk's moment, and he gets very few. From outside a barred door he hears silence where there was shouting, and reads it correctly: silence means something is being arranged. 暗弄 is to work on somebody in the dark, out of sight. The quietest character in the book is the one who understands quiet.
Let us set to."
Five characters, and it is Sha Monk who says them. He is normally the one urging caution while the other two charge.
Pilgrim said, "He is right. Break the door down, and be quick."
Pilgrim agreeing with Sha Monk is rare enough to be worth marking. 說的是 — what is said is right — is still the ordinary way to concede a point in Chinese.
The idiot showed off his powers: up went the rake and down it came with all his strength, and he smashed that stone door to powder; then he shouted abuse in a great voice — "You oil-thieving fiends!
獃子 — idiot, dolt — is the narrator's own affectionate name for Eight Rules, used dozens of times across the novel and never once by way of insult. 築得粉碎 puts the light de between the blow and its result: struck so that it went to powder. And notice what the abuse actually is. Not "monsters", not "demons" — 偷油的賊怪, oil-thieving fiends. The crime everybody remembers is the theft from the town, not the kidnapping.
A passage of two halves, separated by a door. Inside, Tripitaka is talking too much. Outside, three disciples are standing in the dark with nothing to go on but sound — and the moment the sound stops, they move.
The reading of the silence belongs to Sha Monk, and it is the best thing he does in the chapter. He is the least regarded of the three, the one who carries the luggage and agrees with whoever spoke last. Here he hears a demon order quiet, works out that quiet is for doing things unobserved, and says so — and both his brothers do what he tells them. Readers who find him dull should notice how often the novel gives him the correct inference.
The insult at the end is the chapter's real grievance surfacing. Three rhinoceros demons have been posing as Buddhas above the lantern displays at Jinping and collecting the town's aromatic oil as an offering, year after year. They have also kidnapped a monk. But when Eight Rules finally gets to shout at them through a broken door, what he calls them is oil thieves.
