妖敗閉門 行者回莊 The Fiend Bolts His Door; The Pilgrim Returns to the Farm
他兩個自二更時分，直戰到東方發白。那怪不能迎敵，敗陣而逃，依然又化狂風，徑回洞裡，把門緊閉，再不出頭。行者在這洞門外看有一座石碣，上書雲棧洞三字。見那怪不出，天又大明，心卻思量：「恐師父等候，且回去見他一見，再來捉此怪不遲。」隨踏雲點一點，早到高老莊。他两个自二更时分，直战到东方发白。那怪不能迎敌，败阵而逃，依然又化狂风，径回洞里，把门紧闭，再不出头。行者在这洞门外看有一座石碣，上书云栈洞三字。见那怪不出，天又大明，心却思量：「恐师父等候，且回去见他一见，再来捉此怪不迟。」随踏云点一点，早到高老庄。
逐句解 Line by line
The two of them fought from the second watch straight through until the east grew white.
二更 is the second night-watch, roughly nine to eleven; 更 is gēng, not gèng. The fight has run some seven hours.
The fiend could not hold his ground. Beaten, he fled, changed himself once more into a wild wind,
迎敵, to meet the enemy — a military term, used of a creature who was once a marshal. 依然又化狂風: the wind-transformation is his signature and his retreat, both.
went directly back into his cave, shut the door fast, and would not show his head again.
再不出頭 — he would not put his head out again. The idiom is comic and slightly cowardly, and the narrator has chosen it for that reason.
Outside that cave door the Pilgrim saw a stone tablet, and graven upon it were the three graphs: Cloud-Ladder Cave.
石碣, a stone tablet with an inscription: the same furniture as the tablet at the Water-Curtain Cave in chapter one. 雲棧洞, the Cloud-Ladder Cave — a 雲棧 is a plank-road built high along a cliff face.
Seeing that the fiend would not come out, and that the day was now fully light, he thought to himself:
The narrative slips into free indirect thought with 心卻思量. 思量 takes 量 as liáng, the verb.
"My master will be waiting. I had best go back and let him see me, and there will be time enough to take this fiend afterwards."
見他一見: the reduplicated verb with 一 is the vernacular "just to see him a moment." 不遲, "it will not be too late" — Wukong's standing reason for deferring anything.
So with one touch of his foot on the cloud he was back at once at the Gao Farm.
點一點 — a single touch of the toe on the cloud. The line measures the distance between the two halves of the chapter in a half-dozen graphs.
A short bridging passage, and its business is topography. The fight has ranged from the Gao Farm to a nameless mountain; now the mountain acquires a name, cut into stone at the cave mouth — 雲棧洞, the Cloud-Ladder Cave — and with the name the place enters the map of the pilgrimage. The novel is consistent about this: a monster is not fully a monster until his address is known.
Note that Wukong breaks off not because he is checked but because he remembers Sanzang. It is the first time in the novel that the Pilgrim has interrupted a fight out of consideration for anyone. The golden fillet of chapter fourteen has begun to do its work by other means.
