手到擒來 Taken At A Touch
八戒忍不住高聲叫道:「那裡用甚麼人馬?又那裡管甚麼時辰?趁如今酒醉飯飽,我共師兄去,手到擒來。」三藏甚喜道:「八戒這一向勤緊啊!」行者道:「既如此,著沙僧弟保護師父,我兩個去來。」八戒忍不住高声叫道:「那里用甚么人马?又那里管甚么时辰?趁如今酒醉饭饱,我共师兄去,手到擒来。」三藏甚喜道:「八戒这一向勤紧啊!」行者道:「既如此,着沙僧弟保护师父,我两个去来。」
逐句解 Line by line
Eight Rules could not hold himself in, and called out loudly, "What need of any men and horses?
那裡 is the question-word nǎ again, and not really asking anything — where would one use any, meaning nowhere. It is the first of two in consecutive sentences. 忍不住 is the could-not-manage-it shape: he could not hold it in.
"And what has an hour to do with it?
The second of the pair, and the same use — what has an hour got to do with it. Eight characters standing on their own line in the middle of a speech, with the quotation opening in the sentence before and closing in the one after.
"Let us take the moment while we are drunk with wine and full of rice — my brother and I will go, and they will be taken at a touch."
手到擒來 is a set phrase and still in daily use: the hand arrives and the thing is caught, meaning something is as good as done. The reason Eight Rules gives for going now is that they have just eaten well, which is the whole of his military doctrine.
Tripitaka was very pleased. "Eight Rules has been diligent all this while!"
甚 is the intensifier shèn here, very pleased. 一向 has its 一 falling to yí before the falling tone of 向. The praise is warm and, on the evidence of the banquet a page ago, not obviously earned.
Pilgrim said, "If that is so, let brother Sha Monk guard the master, and we two will go."
著 takes zhuó, setting somebody to a job — put Sha Monk on guarding the master. He is left with the luggage for the second time in the chapter, and again without being asked.
Eight Rules interrupts a king in the middle of a question, and he is right. No force is needed and no lucky hour; two of them can do it now. The chapter has spent its whole length on procedure — depositions, warrants, memorials, the correct order of a banquet — and its last piece of business is settled by a pig shouting that none of that matters.
Tripitaka's praise is the sentence to watch. Diligent all this while, said of the disciple who cleared two tables at a state dinner and refused not one cup. Whether the master is being generous or is simply not paying attention, the novel leaves open.
