敗出火中 Driven from the Flames
行者被他煙火飛騰,不能尋怪,看不見他洞門前路徑,抽身跳出火中。那妖精在門首看得明白,他見行者走了,卻才收了火具,帥群妖,轉於洞內,閉了石門,以為得勝,著小的排宴奏樂,歡笑不題。行者被他烟火飞腾,不能寻怪,看不见他洞门前路径,抽身跳出火中。那妖精在门首看得明白,他见行者走了,却才收了火具,帅群妖,转于洞内,闭了石门,以为得胜,着小的排宴奏乐,欢笑不题。
逐句解 Line by line
The Pilgrim, with the smoke and fire whirling upon him, could not find the monster, could not even see the path before the cave gate, and drew back with a leap out of the flames.
The fire-averting sign was not enough. He cannot find the demon, cannot see the path, cannot see the gate -- the smoke has taken his sight, and for a fighter who relies on seeing everything at once that is worse than being burned. He jumps clear.
The monster, watching clearly from the gate, saw that the Pilgrim had gone, and only then put away his fire-gear, led his horde of imps, turned back within the cave, shut the stone door, and — reckoning himself the victor — had the little ones set out a feast and strike up music, laughing merrily; of which no more.
The demon watches him go and draws the wrong conclusion. Two different sounds of 得 inside one sentence: 看得明白 has the light de, joining the watching to how clearly it was done, while 得勝 has the full dé, gaining a victory. 奏樂 takes 樂 as yuè, music, not the lè that means joy -- though there is plenty of that too. 不題, "no more of this," is the narrator changing scene.
The fire does precisely what its own set-piece promised. Wukong is not wounded; he is blinded. He cannot locate the demon, cannot find the gate, and has to leap out of a fight he came into confident. This is the chapter title arriving on schedule: the Mind-Ape suffers defeat by fire, 心猿遭火敗.
The demon then shuts his door and throws a party, having mistaken a withdrawal for a rout. It is a nicely observed piece of overconfidence, and it buys the pilgrims the time they need to go looking for water.
