理上也不通 It Does Not Stand To Reason
行者笑道：「你這夥潑魔，十分無禮。前番哄我出來就咬我，這番哄我出來卻又擺陣敵我。似這幾萬妖兵戰我一個，理上也不通。扯了去，扯了去見我師父。」行者笑道：「你这伙泼魔，十分无礼。前番哄我出来就咬我，这番哄我出来却又摆阵敌我。似这几万妖兵战我一个，理上也不通。扯了去，扯了去见我师父。」
逐句解 Line by line
Wukong laughed and said: "You pack of vile demons are thoroughly without manners.
十分 — ten parts out of ten, and so completely.
The first time you coaxed me out you bit me. This time you coaxed me out and drew up a battle line against me instead.
前番 and 這番 set the two occasions against each other: that time, this time.
Some tens of thousands of demon soldiers fighting me single-handed — it does not even stand to reason.
理上也不通 — it does not go through on the grounds of principle. A complaint about fairness rather than about odds.
Drag him off, drag him off, and let us go to my master."
扯了去 is repeated without variation. Doubling a short command is how this novel writes impatience.
Wukong's objection is not that he was tricked, which he expected, but that the fight was unfair, which offends him. Tens of thousands against one does not stand to reason: he is appealing to a principle of proper contest, and he is doing it while holding a rope tied to a man's heart. The novel lets the inconsistency sit there without comment.
It is worth noticing what he asks for. Not an apology, not surrender, but that they come with him to Tripitaka. Everything in this chapter routes back to the same objective, and Wukong never loses sight of it even while enjoying himself thoroughly. The pilgrimage is the point; the demon on the rope is transport.
The doubled command at the end is the same device used earlier for very well then and for I am not coming out. When this novel wants a character to sound like a person rather than a page, it repeats a short phrase. It is the closest the prose comes to recording a tone of voice.
