鐵棒萬夫 An Iron Rod Ten-Thousand Cannot Withstand
眾怪道:「大王,你沒手段,等我們著幾個去報大大王,教點起本洞大小兵來,擺開陣勢,合力齊心,怕他走了那裡去?」二魔道:「你們不曾見他那條鐵棒,有萬夫不當之勇。我洞中不過有四五百兵,怎禁得他那一棒?」众怪道:「大王,你没手段,等我们着几个去报大大王,教点起本洞大小兵来,摆开阵势,合力齐心,怕他走了那里去?」二魔道:「你们不曾见他那条铁棒,有万夫不当之勇。我洞中不过有四五百兵,怎禁得他那一棒?」
逐句解 Line by line
The fiends said: "Great King, if you've no means for it, let us send a few to report to the Great Great King, that he may muster all the soldiers of the cave, high and low, deploy them in battle-array, and join every force with a single heart — then where could he escape to?"
著幾個去 (zhuó jǐ gè qù) takes 著 as zhuó, "to send, to dispatch." That is the third of this character's readings the chapter has now used: zhe for an action left running, zháo for one that lands on its target, zhuó for sending someone off. Same character every time, and only the job it is doing tells them apart. 走了那裡去 is a rhetorical "escape where, exactly?" -- meaning nowhere -- so 那 is nǎ. 大大王 is the overlord, the Great Great King.
The second fiend said: "You've not seen that iron rod of his — it has a valor ten thousand men could not withstand.
萬夫不當之勇 (wàn fū bù dāng zhī yǒng), "a valor ten thousand men could not stand against," is stock praise for a champion; 當 is dāng, "to withstand, to face." 那條 uses 條, the measure word for long thin things -- the sort of counter English lacks and has to render as "that length of rod."
"In my cave there are no more than four or five hundred soldiers — how could they bear up under a single blow of that cudgel?"
禁得 (jīn de), "to bear up under" -- 禁 read jīn, "to endure," not the jìn of prohibition, and 得 the toneless marker of possibility. 那一棒, "that one blow," with 那 back to the pointing nà. The arithmetic is the point: four or five hundred troops against a single swing.
The rank and file propose the obvious thing: send for the overlord's garrison, form up, and swamp him with numbers. Their closing question -- then where could he escape to? -- is the confidence of soldiers who have never met the man.
Their captain, who has just watched the cudgel routine, knows better, and he answers with arithmetic rather than argument: a rod ten thousand men could not stand against, against four or five hundred troops of his own. That settles the case against a frontal assault, begun in the previous scene, and clears the ground for the stratagem. Note 禁 read jīn, "to endure": a single blow is more than his whole garrison could survive.
