老魔慌了道：「這一進去，又不肯出來，卻難也，卻難也。」
老魔慌了道：「这一进去，又不肯出来，却难也，却难也。」
The old fiend took fright and said: "If he goes in this time, he will refuse to come out again. That would be hard indeed, hard indeed."
難 reads nán, difficult, not the nàn that means a calamity.
行者道：「我有本事外邊就可以解得裡面繩頭也。
行者道：「我有本事外边就可以解得里面绳头也。
Wukong said: "I have the skill to loosen the inner end of the cord from out here.
解得 keeps dé: the character forms a settled verb with the one before it rather than linking to a result.
解了可實實的送我師父麼？」
解了可实实的送我师父么？」
Once it is loosed, will you truly see my master across?"
實實的 — really and truly. Doubling the character presses the demon for a firmer answer than he has given so far.
總評 Commentary
The offer to go back inside is the cruellest thing Wukong says in the chapter, and it is phrased as helpfulness. He knows the demon cannot accept and knows exactly why, which is the point of making the offer: to hear it refused, and to watch the fiend explain that he no longer trusts his own mouth.
The old fiend's reply is the first honest assessment anyone has made of the situation. If he goes in this time, he will refuse to come out again. That is simply true, and it is a considerable advance on his earlier planning, which mostly consisted of biting things.
Then comes the question underneath everything: will you truly see my master across? Wukong has put it directly twice so far, and the demons have volunteered the promise five times without being asked. That ratio is the whole problem. A pledge repeated unprompted is not reassurance, and the novel shows Wukong extracting a fresh undertaking each time rather than relying on any of the earlier ones.
