Cthulhu Gonfalon Chapter 235:

　　 When saving the great drought that affected the entire continent of the main plane, Sui Xiong once produced a lot of salt, really, so much that can be piled into a mountain.

　　Of course, these salts are coarse salt, bitter and astringent. Maybe the poor people don’t mind the taste, but Sui Xiong himself dislikes them very much. In his opinion, this kind of salt is rubbish. Not only does it taste bad, but it also contains a lot of harmful minerals. No matter how little scientific knowledge Sui Xiong lacks, he also knows that sea water cannot be drunk. The key reason for not drinking is not the dirty, but the large amount of harmful minerals in it.

　　Sui Xiong once heard a popular science, saying that the reason why seawater is not drinkable is that the excessive salt content is one aspect, and the various other minerals contained in it are another aspect. He doesn’t remember exactly what those minerals are, but the name still has an impression, what vomiting salt, Epsom salt… Just listen to the name and know what the consequences will be if you eat it.

　　 So even though he got a mountain of salt by the way when he got fresh water from the sea for disaster relief, he didn’t find a good way to use it. Finally, he gave Palin, the chief scientific researcher of the Masked Void Church, to study how to purify these coarse salt into edible salt.

　　 There is also salt drying technology in this world, and naturally there is also a way to turn coarse salt with a lot of impurities into refined salt with almost no impurities. But those methods require the use of magical assistance, and the cost is too high. Apart from being enjoyed by the upper class, they are not of great practical value.

　　 The special spell “Purify Coarse Salt” is an intermediate level. The mage who can cast this spell is at least equivalent to a knight, and he casts the spell about two or three times a day, which can purify ten to ten in total. Only five catties of salt. “Purification of salt water” is a bit lower, close to the middle-level mage can use it, an ordinary middle-level mage can use about ten times a day, but considering that the salt can be obtained after the brine is evaporated, the efficiency of making refined salt is actually not as good as “Purify coarse salt.”

　　 Generally speaking, considering the human resources and casting materials, a pound of refined salt purified by magic is worth about 20 gold coins—this is the cost, the pure production cost, and only the cost of sun-dried salt Can be so low. If it is boiled salt, add three to five gold coins per catty. In addition to transportation… the refined salt in the inland areas can sometimes even sell for more than one hundred gold coins per catty!

　　 This is undoubtedly an extremely profitable industry, but in fact very few people are engaged in it, very very very few. Because in most cases, people would rather eat a pound of coarse salt that does not exceed a metal coin.

　　What? You say it tastes bad? You say it is harmful to the body?

　　 Just eat less!

　　 So the market for refined salt is not large, and the profits are not huge.

　　The mission that Sui Xiong gave Palin was to study a method of purifying coarse salt at the lowest possible cost. As for the research budget, the old rule is that you don’t have to care about the money and spend as much as possible.

　　 Even so, it took Palin more than ten years to complete this research.

　　 And the solution he and the researchers he led finally found was surprisingly simple.

　　 is so simple, it only needs two words.

　　 “powder” and “washing”.

　　Yes, these are the two words that Palin uses to name this salt.

　　The specific method is not complicated at all. First, the coarse salt is ground fine, as fine as possible, as fine as flour is the best. Then pour them into the salt water. As more and more salt is dissolved in the salt water, the salt gradually becomes insoluble in water-in physical terms, it is called “saturated”.

　　 This kind of saturated brine can no longer dissolve the salt, but it can dissolve the impurities contained in the salt. Use it to wash the finely ground coarse salt powder, and you can get refined salt with very few impurities.

　　After washing, the fine salt obtained has very little impurities. If necessary, you can also use this salt to make saturated brine for the second washing; or even the third…

　　 Generally speaking, the fine salt obtained after washing three times has no peculiar smell at all, and it is very pure. Palin also added some filtering, sedimentation and other impurity removal methods in this process, and the final result is a refined salt that is as delicate as rice flour, white and crystal clear, and tastes excellent.

　　 he named it “powder washing salt”.

　　 Sui Xiong listened to his report and inspected their research institute. He couldn’t help but be sincerely happy for them.

　　”This is a great achievement!” He said, “Pallin, if I estimate it well, if you are willing to spread this technology widely, with this feat, it may be enough to conjure the gods-of course , I guess it’s just the lowest level of weak supernatural power.”

　　 Palin smiled, without any excitement.

　　 This is not because he looks down on weak divine power, no matter how “weak divine power” is, it is also a god, an immortal existence, a level that mortals cannot reach. It’s just what he is after, not this.

　　”In the process of researching refined salt, it was not me who made a great contribution.” He said, “It was Fera Kenki.”

　　 Sui Xiong certainly knows who Fera Kenji is. Known as the “green magician”, he was originally a pig-headed cook~IndoMTL.com~ Later, he had some adventures and swallowed a vain plan. The soul of the ancient wizard who took his body and resurrected became a magician. Later, with the help of Milomon and Maduo, he studied and created the blue magic characterized by “swallowing monsters and learning spells”…

　　 He also saw Fera in the research base. Because the pighead’s lifespan was not long, Fera was already covered with gray hair, and his plump face gradually became thinner, proving that his life was in the late stage—— The battle with the soul of the ancient wizard in those days certainly benefited him a lot, but also caused him to lose a lot of life. In addition, in order to make up his long-cherished wish with his old rival Ruby Sliu, he used taboo tactics to waste his life and defeated his opponents in the world’s No. 1 martial arts tournament, and reported that he was underestimated and bullied in his youth. The hatred.

　　 Now he is almost in his dying year. Although he is not so trembling to walk, in fact, even if he falls down tonight and does not wake up tomorrow, it is not a strange thing.

　　 Sui Xiong still knew about his experience, but Sui Xiong did not expect that this has a short temper and limited talents. It seems that only good luck and the help of friends can be used to become a pighead of the magician. He is the key figure in the invention of crude salt purification technology.

　　 Looking at the peaceful smile on Ferra’s old face, he couldn’t help but think of a famous saying in his heart.

　　 This is really… people can’t look at all!
