忽然不見 Gone In A Moment
行者笑道:「不打緊,就去就來。」那老者道:「且住,吃些茶飯,辦些乾糧,須得兩人做伴。那路上沒有人家,又多狼虎,非一日可到,莫當耍子。」行者笑道:「不用,不用。我去也。」說一聲,忽然不見。那老者慌張道:「爺爺呀!原來是騰雲駕霧的神人也。」行者笑道:「不打紧,就去就来。」那老者道:「且住,吃些茶饭,办些干粮,须得两人做伴。那路上没有人家,又多狼虎,非一日可到,莫当耍子。」行者笑道:「不用,不用。我去也。」说一声,忽然不见。那老者慌张道:「爷爷呀!原来是腾云驾雾的神人也。」
逐句解 Line by line
Pilgrim laughed and said, 'That's nothing at all. I'll go and be back directly.'
不打緊, "no matter, nothing to it." He has just been told the round trip takes a month.
The old man said, 'Wait a moment. Take some tea and rice, have dry rations put up, and you'll need two men to go with you.'
乾糧 is dry provisions for the road, so 乾 is gān and not the qián of the heaven-trigram. 須得, "you will need," with 得 as dé.
'There are no houses on that road, and wolves and tigers in plenty. It cannot be reached in a day. Don't take it for a game.'
當 is dàng here, "to take something as, to reckon it as," not the dāng of position and time in 當面 or 當年. 耍子, "a lark," with the light ending. The advice is exactly what you would give any traveller, and exactly what does not apply to this one.
Pilgrim laughed. 'No need, no need. I'm off.'
The refusal, the doubling and the departure fit into eleven characters. Rations, companions and a month's walk are all disposed of without argument.
He had barely spoken when all at once he was gone.
說一聲, "he said a word," and then 忽然不見, "suddenly was not seen." The narrator refuses to describe the departure at all, which is the whole joke — the reader is left standing in the room with the old man.
The old man said in a fluster, 'Good heavens!'
爺爺呀 is a cry of shock, literally an appeal to a grandfather or a lord.
'So he was a divine being, one who rides the clouds and drives the mist!'
原來是 marks a realisation arriving too late — "so that's what he was." The old man has spent the entire scene giving sound travel advice to somebody who needed none of it, and the novel lets him work this out only once the room is empty.
The old man's advice is entirely sound and entirely useless. Eat first, take dry rations, bring two companions, mind the wolves and tigers, and understand that it cannot be done in a day. Every item is what you would properly say to a traveller setting out, and not one of them applies to the traveller in front of him.
Pilgrim's reply runs to eleven characters and disposes of all of it. The comedy is in the proportion: a paragraph of careful provision met with "no need, no need, I'm off." The novel has run this joke before, but it is sharpened here by how genuinely considerate the old man has been.
Then the narrator simply removes him — 說一聲,忽然不見 — and declines to describe the departure at all. We stay behind in the room, and the last word goes to a man working out, too late and to nobody in particular, that his guest could fly.
