"Is it really salt" After tasting the contents of Sun Ying's bowl, Sun Ying was stunned, stood there stunned, and asked again in disbelief.

Li Yan nodded again in confirmation.

……

…………

Sun Ying felt as if she was crazy, and she always felt that Li Yan's development of edible salt was a bit fantastical.

You must know that there are only a few ways to provide edible salt, in addition to extracting salt from natural salt springs, and then leading seawater into the ditch, drying seawater to extract salt, hundreds of years of the Ming Dynasty is relying on this method to provide everyone with salt for eating and cooking, and the output of salt is still small, plus to be transported back from a long distance, the price of salt has risen all the way, resulting in ordinary people eating salt is a luxury, and the large supply and demand of salt is only a privilege of princes and ministers.

Ordinary people can't afford to eat it if they want to, and the salt that the public wants to get even if they are desperate...... It was developed by his own father-in-law?

Sun Ying suddenly had a feeling of stepping on cotton under her feet, what is this? What a big deal!

……

…………

Li Yan's development of salt is actually a very accidental thing, because his family is not short of salt, so there is no need to make salt, but because it is winter, and it happens to be snowing today, Li Yan thought that the highway in his previous life was sprinkled with salt to melt the snow, so he had the idea of making salt by himself.

There's only one purpose...... Clear the snow.

I have to say that Li Daguan's ideas are really wild, and people can't wait for it, and the salt that is regarded as gold arrives in Li Yan's hands...... It's actually used to clear the snow in your own house!

I don't know if those public candidates will directly smack Li Yan in the face when they know Li Yan's thoughts, damn it, my family can't even eat salt, and you still have to use it to clear the snow......

Li Yan was very proud, and was about to show off, when he suddenly saw Zhang Tao lying on the ground, and was stunned.

"Madam, why did Zhang Tao provoke you? You knocked him out? ”

Hearing this, Sun Ying's face darkened, and the housekeeper on the side leaned into Li Yan's ear and whispered a few words, and Li Yan immediately closed his mouth wisely and cast an embarrassed look at Zhang Tao.

It's a pity that Zhang Tao can't see it for the time being, and I don't know if he will stay away from Li Yan as soon as he wakes up, after all, his boss is a master who will release poison gas at will.

……

…………

After putting the liquid in the bowl on the kang head and steaming it dry, Li Yan rubbed it carefully with his fingers, it was not bad, the size of the crystals was exactly the same as normal edible salt, it seemed that his knowledge was still not in vain.

Li Yan put away the porcelain bowl with emotion, the method of making edible salt is very simple, sodium hydroxide plus hydrochloric acid can get sodium chloride and water, that is, liquid salt.

Sodium hydroxide is easy to find, this kind of thing called caustic soda in ancient times can be easily bought, hydrochloric acid is a problem, but under the research of Li Yan, it was still studied by himself, and the sound in the room before was that there were some small accidents when making hydrochloric acid, but the number of attempts Li Yan also had experience, and he minimized mistakes.

As for the smoke of Zhang Tao to faint, that is, the most serious time, it was that after the success, Li Yan was too excited, his hands trembled, did not control the amount of raw materials, and poured the hydrochloric acid into the bowl before it was completely extracted, to put it bluntly, Zhang Tao was completely stunned by an accident......

The next day, the neighbors around the Li Mansion discovered such a strange scene: when everyone else was in full swing to remove the snow, the master of the Li family was directing the servants of the family to sprinkle a layer of white flowers into the snow, and some curious people went over to dip a little of their fingers in their mouths and tasted it, and found that they were sprinkled with table salt!

Suddenly, everyone was stunned, they didn't know how high the price of salt was, and they didn't know how much it spilled out at once, I'm afraid it would cost a hundred taels if it wasn't eighty taels, right?

All of a sudden, Li Yan became synonymous with the loser, and even some of the more capable losers in the capital admired Li Yan, and they could compare with other things, but they really didn't dare, and they didn't dare, unless they could convince their Lao Tzu not to whip themselves to death.

Those losers have scruples, but Li Yan doesn't need scruples, not only does he have no scruples, Li Yan sprinkled salt and sprinkled it very happily, and the next day he summoned all the captains of Jinyiwei to clear the snow along the streets of the capital, as for the method...... Or sprinkle salt, of course.

After several large-scale experiments, Li Qianhu has no shortage of salt in his hands, and he said very unkindly that there is as much salt as Li Yan wants, and if anyone dares to say in front of Li Yan, 'I have traveled more roads than you have eaten salt', Li Yan will definitely stuff all the salt in his house into this person's mouth.

There are thousands of captains in the capital, not counting the official captains, there are also many hired people, all of whom were sent out by Li Yan to sprinkle salt and clear snow everywhere.

Jin Yiwei's work efficiency was very fast, and under the instructions of Li Yan, he soon sprinkled salt on every street in the capital.

Jin Yiwei's performance is very good, in addition to the voluntary snow clearing is praised by everyone, many people are curious about where did Jinyiwei get so many salt people?

Soon, someone got the news that these salts were distributed by Li Qianhu and were specially used to clear the snow.

Hearing this, everyone was stunned, this is the news from the mouth of the captain of the Jinyi Guard, there will definitely be no fake, but the question is where did Li Yan's salt come from? Could it be that he robbed the warehouse where the official salt was stored?

On the first day, a public servant sent someone to ask Li Yan about the salt, and Li Yan said that it was his own.

The next day, the ministers from all walks of life sent people to find out the truth, and Li Yan said that it was his own.

On the morning of the third day, news came from the palace that Emperor Hongzhi asked people to ask about the source of salt, but Li Yan still said that it was his own.

Subsequently, another order came from the palace, and Emperor Hongzhi announced that Li Yan would enter the palace.
