Xiulote's face stalled. He only had a vague memory of that mnemonic verse, and as for the specific metalworking machinery, it was naturally impossible for him to remember. The King simply pointed at the end and explained.
"Set up water wheels by the riverside, then connect them to forge hammers, and they can be used to forge metal armor plates or rough Armor casts. In addition, water mortars can process grains. Oh, right, there are also windmill gristmills..."
Xiulote added "windmill" under the "simple machinery" section next to him, which already had many jumping terms including "weaving loom," "spinning machine," "cotton gin," "semaphore tower"... Of course, in the King's mind, these machines were just nouns, with only a general idea of their functions. There was one exception... "steam engine"!
