After staying in the club for nearly an hour, Li Yuanjia finally got a little tired.

"Your Majesty's letter to you, Your Majesty."

"Oh? Hurry up and give it to me! ”

As soon as he returned to the mansion, he saw the little eunuch running from Jiucheng Palace, Li Yuanjia's heart moved, and he quickly took the letter from the second child from him.

After taking the letter, he just wanted to open it, but after glancing at the little eunuch, Li Yuanjia turned his head to look at Han Lucheng: "Take him down to have a good rest, I will prepare the reply early tomorrow morning." ”

"Yes, my lord."

"Thank you, King!"

After the two saluted separately, they stepped back one after the other.

And Li Yuanjia couldn't wait to open the emperor's "family letter", and then it was exactly the same as the last time, and he was stunned after reading it: "Damn!" What does this dick mean? This...... Is this to encourage me to go to the beach to dry salt, and then I can sell salt at will? This ......"

After reading the letter several times, Li Yuanjia was sure that he was not dazzled and did not read it wrong.

Can it still be like this?!

This time, Li Yuanjia didn't rack his brains to reminisce, but took out a "copy" of the letter he wrote to the second child that day, a version that he copied by himself, and then read it carefully several times.

In the end, Li Yuanjia was sure that he must have made it clear.

The low cost and high yield of seawater salt-drying were clearly stated in his letter to the emperor, and Li Yuanjia also clearly told Li Shimin that as long as he sent people to mine the minerals needed on a large scale in Tongbai County, it would be much easier to purify sea salt in the future, and the price of refined salt would be suppressed......

Isn't that appealing enough?

Anyway, after reading the two letters for a long time, Li Yuanjia opened his mouth and stared, his face full of bewilderment: "I'll go to it, is this still ancient?" It's not that salt in ancient times was extremely valuable, and it involved huge benefits, and no one was willing to let it go...... Well? Wrong! ”

Thinking about it, he was suddenly stunned, and Li Yuanjia's brows furrowed.

There's definitely something wrong with this!

It won't be ......

After reading the latest letter he wrote, the second child still doesn't believe in the efficiency of seawater salting, and he doesn't believe that he can purify rough sea salt into refined salt at a very low price, right?

After frowning and walking around the study a few times, the more Li Yuanjia thought about it, the more he felt that it was possible!

After all, the things he wrote in the letter were too simple to be simple after more than a thousand years, but in the thirteenth year of Zhenguan, it did sound like telling a mythical story - it only takes four or five salt drying craftsmen to dry the sea salt boiled by hundreds of salt workers in a year, or even more? It only takes some time to turn coarse salt into refined salt?

"No, I have to write another letter!"

After biting his lower lip, Li Yuanjia sat down directly at the desk, wanting to write a letter to Li Shimin and explain this matter in detail.

It's just that when he just spread out a piece of paper and was about to call Chunyan to come in to sharpen his ink, Li Yuanjia's movements suddenly stopped again, and he slowly put down the pen he had just picked up in his hand.

"It doesn't seem to be useful to write another letter!"

Subconsciously rubbing his nose, Li Yuanjia leaned back on the back of the chair with a headache: "After all, my side has just started, and they only dried more than 100 catties of coarse salt, and then Ma Liang and they purified a few catties of refined salt, and the cost is quite ...... The emperor didn't think much of what I said in my letter, I'm afraid he just felt that the yield was not high, and the cost of purification was too high, so he wasn't interested, right? ”

Tilting his head, Li Yuanjia felt that this was very likely.

For some things that subvert his common sense, even Li Shimin is afraid that it is difficult to believe it, right? So it seems natural to reply directly and let Li Yuanjia do it himself first and try it?

"Hmm......"

Flipping through the emperor's reply letter to himself again, Li Yuanjia looked at it a few times, and then began to tap his fingers on the desktop in front of him, and pondered carefully.

If so, it's an opportunity.

Anyway, the steps of drying salt have already been mastered by a few people, even if the efficiency is lower now, it doesn't matter, and it will always improve little by little if you think about it slowly. As for the purification of coarse salt, it seems that the same is true, and small-scale fine processing is fine, but if it is really large-scale purification, it is connected with seawater salt......

"If you take your time, it seems like a good idea?"

In an instant, Li Yuanjia made up his mind: "Since this is the case, let them do it first...... Hehe, this benefit of salt, we Han Wangfu will also earn it first! ”

Before I did it, Li Yuanjia also thought that this seawater salt must be very simple, but after I really let people do it, I found that in fact, these things are not so easy. For example, how to make seawater evaporate faster, make salt crystallize faster, etc., all need to accumulate experience. There is also coarse salt purification, if you want to increase the scale, the time required is definitely not short.

However, in this process, Han Wangfu should not be able to lose money.

After all, the price of salt is there, and the quality of purified sea salt is also there, Li Yuanjia is not afraid that he will not be able to sell it when the time comes, and he is not afraid that the money sold will not even recover the cost.

"Hehe, let's do it then!"

Carefully putting away the emperor's letters, Li Yuanjia finally made up his mind.

Under normal circumstances, of course, he would not go back to touch such a thing as salt, after all, the interests were too great, there were too many involvement, and more importantly, it was easy to arouse the emperor's suspicion and suspicion. But now that he has this letter, what else does Li Yuanjia have to be afraid of?

Dry!

Having made up his mind, Li Yuanjia opened his mouth and shouted: "Spring smoke, spring smoke? Let Han Lucheng hurry up and come over...... By the way, the craftsman who came back from the East China Sea, let him come over too......"

……

In his study, while Li Yuanjia was waiting for Han Lucheng, he was thinking about the plan to increase the number of people in the East China Sea and increase the scale of salt drying, and at the same time, he was also thinking about letting people go to Tongbai County to open a mine to ensure that the minerals used in the future were purified for sea salt.

And in another room in the mansion, Fang Fengzhu was not idle.

"In other words, that Chen Lian has become honest?"

After listening to the housekeeper's reply, Fang Fengzhu raised his eyebrows and asked indifferently: "Didn't you say any more nonsense in the workshop?" What about after you get out? ”

"No, none."

Taking a deep breath, Han Lucheng said in a low voice: "There are some of us in the workshop who are staring at it all day, Chen Lian has become very honest, and he has never dared to say anything about the palace again." And he's now in the workshop almost from morning to night...... By the way, the morning before yesterday, he seemed to have received a letter from Jiucheng Palace. ”

"Oh?"

Hearing the words Jiucheng Palace, Fang Fengzhu's eyes suddenly moved.

The emperor has to stay for several months in the Jiucheng Palace, and most of the important ministers in the court will naturally have to pass, otherwise the operation of the center will become a problem. So it's really hard to tell who wrote a letter from Jiucheng Palace.

However, after pondering for a while, Fang Fengzhu still waved his hand and said: "You continue to keep an eye on this matter, if you can find out the person behind Chen Lian, it will be great......"
