And this "series of processes" is precisely the secret formula held by the noble family.
Without these procedures, even if salt is boiled out, it can't be eaten directly, cough cough, it's easy to poison people!
What the noble family monopolizes is not just the salt fields and salt mines, but also these secret formulas.
If there were a secret formula, Emperor Yongcheng would also want to encircle a stretch of beach, then make salt and sell it.
But the problem is, he doesn't have it!
Now, suddenly hearing of another method of making salt, which doesn't waste iron pots, firewood, and other tools, Emperor Yongcheng, though incredulous, was nonetheless tempted.
"Exactly! No need to waste any iron pots or firewood, simply by harnessing the power of nature, we can obtain top-quality sea salt!"
Thanks to web novel authors among certain research parties, who describe some processes very thoroughly in their stories.
