更不曾與他 The Immortals Never Argued
自妖精到此居住，占了他的濯垢泉，仙姑更不曾與他爭競，平白地就讓與他了。我見天仙不惹妖魔怪，必定精靈有大能。」自妖精到此居住，占了他的濯垢泉，仙姑更不曾与他争竞，平白地就让与他了。我见天仙不惹妖魔怪，必定精灵有大能。」
逐句解 Line by line
"Since the monsters came here to live, they have taken over his Filth-Cleansing Spring, and the immortal maidens never once contended with them for it — they simply let them have it, for nothing."
曾 is céng here and the base gets it right without help, which is the point: it is the 可曾 question-form that misleads a machine, not the character. 更 is gèng, still less, not at all. 平白地 — for no reason, out of nowhere, without a fight.
"When I see heaven's own immortals decline to provoke a demon, I am sure the creature has great power in it."
惹 is rě, to provoke or stir up. The inference is a piece of reasoning by proxy: he cannot measure the monsters directly, so he measures the people who backed away from them. It is the most intelligent thing anybody says in the chapter.
The old god cannot assess the threat himself, so he assesses it by watching who else backed off — and the people who backed off were immortals from heaven.
That is genuinely good reasoning, and it is coming from the character the chapter has been treating as a joke. He knows the limits of what he can see and he substitutes a proxy measure. Anyone who has judged a firm by who declined to work with it has made the same move.
The detail about the spring is unsettling on its own terms. Seven heavenly maidens had a bathing pool, seven spiders moved in, and the maidens gave it up without a word of argument. Nobody in this chapter is willing to make a stand about anything until Pilgrim arrives.
