Sell nine sets of seven words to make 2 million swords.

Correct sets will generally only attract one buyer - if there is more than one buyer then the set includes some words from another valid set. If you get more than two buyers then the set is almost certainly wrong.

The highlighted words in the story indicate the word pattern you should be looking for.

Only take buyers who offer around 220k or you will not reach your total.
