老孫保唐僧取經，從廣裡過，帶了個摺疊鍋兒，進來煮雜碎吃。將你這裡邊的肝、腸、肚、肺，細細兒受用，還夠盤纏到清明哩。」那二魔大驚道：「哥啊，這猴子他幹得出來。」老孙保唐僧取经，从广里过，带了个折叠锅儿，进来煮杂碎吃。将你这里边的肝、肠、肚、肺，细细儿受用，还够盘缠到清明哩。」那二魔大惊道：「哥啊，这猴子他干得出来。」
逐句解 Line by line
"Old Sun, escorting the Tang monk after scriptures, came through the Guang country and brought along a folding pot. I have carried it in here to boil up the offal and eat."
摺疊鍋兒 — a folding pot — keeps 兒 at full weight as ér. 廣 is the Guang region, the far south, and the detail is a small piece of commercial geography: southern ironware had a reputation, and a collapsible travelling pot is exactly the sort of thing a pilgrim would buy on the road.
"I shall take the liver, guts, stomach and lungs you have in here and enjoy them at my leisure — enough to keep me provisioned till Qingming."
將 is jiāng, the disposal grammar. 盤纏 is travelling money and provisions. 清明 is the Clear and Bright festival in early April, when families sweep the graves — so he is promising to eat his way through to the tomb-sweeping season, which is a joke about funerals as well as about lunch.
