水黿之第 The Mansion of the Water Turtle
行了又有百十里遠近,忽擡頭望見一座樓臺,上有「水黿之第」四個大字。沙僧道:「這廂想是妖精住處,我兩個不知虛實,怎麼上門索戰?」行者道:「悟淨,那門裡外可有水麼?」沙僧道:「無水。」行者道:「既無水,你再藏隱在左右,待老孫去打聽打聽。」行了又有百十里远近,忽抬头望见一座楼台,上有「水鼋之第」四个大字。沙僧道:「这厢想是妖精住处,我两个不知虚实,怎么上门索战?」行者道:「悟净,那门里外可有水么?」沙僧道:「无水。」行者道:「既无水,你再藏隐在左右,待老孙去打听打听。」
逐句解 Line by line
They had gone another hundred li and more when, raising their heads, they saw a tiered tower, and above it four great characters: MANSION OF THE WATER TURTLE.
水黿之第. 黿 (yuán) is the great soft-shelled turtle; the sign names the true owner of the house, not its present occupant — a point the chapter will collect at its close, when the dispossessed 老黿 appears to ferry the pilgrims over.
Sha Monk said: "This must be the fiend's dwelling-place. We two know nothing of what is inside — how are we to go up to the gate and offer battle?"
住處: 處 chù, the nominal "place" — contrast the verbal chǔ of 處置. 上門索戰 is the formulaic challenge-at-the-gate that opens most combats in the novel.
Pilgrim said: "Wujing, is there water inside that gate, or outside it?"
那門 deictic 那 nà, pointing at the gate now in view. The question is tactical: dry ground inside would restore Wukong's freedom of action.
Sha Monk said: "There is no water."
The two-character answer is left bare, and the plot turns on it: with no water within the gate, Wukong can drop the water-repelling sign and act freely once inside.
Pilgrim said: "Since there is no water, hide yourselves close by, and let old Sun go and make inquiries."
藏隱: 藏 read cáng, "to hide," not the zàng of 三藏. 打聽打聽 — reduplication for a casual, exploratory action.
The block is short and almost entirely functional, but it plants the chapter's most important object: the signboard reading 水黿之第. The house belongs to a turtle, and the fiend now sitting in it is a usurper — the 靈感大王 having driven the old 黿 out and taken his mansion. Nothing is made of this yet; the detail simply stands over the gate while the fighting goes on beneath it, and is redeemed at the end of the chapter when the turtle offers to carry the pilgrims across the eight hundred li of river in return for a question to be put to the Buddha.
Tactically, Sha Monk's flat 無水 is the hinge of the whole underwater assault. Wukong cannot fight while holding the 避水訣; if the ground inside the gate is dry, he can enter as himself. The reconnaissance that follows is his standard method — transform small, go in, ask a servant a direct question — and it works here for the same reason it works elsewhere: the demon's household is large, its members do not know one another, and no one thinks to doubt a shrimp.
