Traveling through the Gaowu Tang Dynasty, Li Kuan and Li Shimin became the second sons of the Prince

"Xuan Ce, you know what I'm going to say next." His Royal Highness the King of Chu didn't want to swear today, but he felt that the Five Surnames and Seven Families were swearing dirty: "How about... I do something bad to them again?"

“Your Highness…” Wang Xuance felt that King Chu was becoming naive again: “If you do this now… Chang’an… will take it seriously…”

"That's right." His Royal Highness the King of Chu nodded after hearing this: "It's all that stupid emperor's fault! The prosperous Zhenguan Era has been delayed because of this stupid emperor... As a wise king, I feel so miserable!"

"Your Highness, I have some coconut chestnuts here, they are sweet." - I don't know if Gangzi has been in conflict with King Chu recently. Anyway, this guy doesn't even know what His Highness the King of Chu and Wang Xuance talked about before - but when he walked into the hall, he heard His Highness the King of Chu say "I feel bitter", so Gangzi, who rarely felt guilty, took the initiative to offer the coconut chestnuts he had just picked.

As everyone knows...

His action was like patting the horse's hoof.

"Gangzi, if you have nothing to do, just stay outside. I don't have time to deal with you now." Upon hearing this, His Royal Highness the Prince of Chu glared at Yuan Tiangang unhappily, then he closed his eyes and thought for a moment before slowly speaking: "Xuan Ce, go and warn them on my behalf - they have no right to interfere in the affairs of the royal family. If anyone dares to break the rules again, I will let them see how powerful the Prince of Chu's Palace is! In addition, this matter is not over yet, I must immediately fight back!"

"Yes!" Wang Xuance hurriedly bowed and accepted the order, but then he couldn't help but ask curiously: "But Your Highness...how are you going to respond?"

"I have a brilliant plan!" - His Majesty the King of Chu smiled upon hearing this. Then, seeing that Gangzi was still standing in front of him, he simply snatched the coconut with the bamboo tube just inserted from him and took a sip: "As the saying goes, if you live by the mountain, you can eat from the mountain; if you live by the sea, you can eat from the sea. What I am going to do next... is to make salt!"

Do it when you think of it. This is one of King Chu's life creeds.

Therefore, within a few days, His Royal Highness the King of Chu ordered the construction of several hundred acres of scattered salt ponds on the seashore.

“Your Highness, introducing seawater into this salt drying pond (salt field) and exposing it to sunlight can indeed leave a layer of coarse salt on the surface of the salt field, but the quality of this coarse salt is really…” Li Chunfeng was one of the retainers with the lowest presence around His Royal Highness the King of Chu. He seldom expressed his opinions on areas he was not familiar with. But now that he saw that His Royal Highness the King of Chu was planning to make poisonous salt to sell, he naturally could not accept it.

"What are you thinking about?" His Royal Highness the King of Chu saw that Li Chunfeng was "risking his life to make a direct remonstrance", and immediately pointed to the two salt fields in front of him and said: "This one is used to dry salt, and the other one is used to make brine. The seawater in the drying salt pond is only half or less than that in the brine pond. After the seawater in the drying salt pond is exposed to the sun and produces a layer of coarse salt, the seawater in the brine pond will become turbid, thus forming brine.

After that, we carefully collect the coarse salt from the salt pool with a scraper, and then pour the coarse salt into the brine pool, and then let the brine pool continue to be exposed to the sun - after the brine in the brine pool is dried, the coarse salt produced can be used. "

Of course, the King of Chu was a wise king, so this was not the end - if you want to continue to purify it, you need to use plant ash - transport the crude salt produced by the brine pool to the salt workshop, pour it into a large barrel, then add boiled and cooled clean water, and then add plant ash. Finally, after the plant ash settles, we open a large hole at the bottom of the barrel, and then use a hollowed-out large green bamboo as a conduit, insert it into the bottom of the barrel - in the bamboo tube of the large green bamboo, lay a layer of charcoal, a layer of cotton cloth, and a layer of fine sand. After these layers of filtration, the salt water from the barrel can be put into a large pot for boiling - and this time the output is refined salt.

On this basis, if you need to further improve it, you have to use beans - grind the beans into soy milk, and then add the soy milk into the salt water in a certain proportion during the final boiling process - this will produce the finest refined salt.

However, King Chu felt that there was no need to tell everyone about all of this, because just the first few things were enough to shock his retainers for a long time.

And the fact was just as he expected. After listening to the explanation of His Royal Highness the King of Chu, the retainers all looked stunned.

When His Royal Highness the Prince of Chu saw everyone's reaction, he immediately put his hands on his hips and said smugly, "What? So you really treated me as your husband?"

"No..." Li Chunfeng was still digesting the knowledge taught by His Royal Highness the Prince of Chu, while Gangzi beside him had already begun to doubt his life: "Your Highness... these techniques... how did you know?"

"Guess?" His Royal Highness the Prince of Chu never explained his actions to others throughout his life: "You all said that I was stupid before, but I am not like that! In fact, those were just my disguise."

"Your Highness the King of Chu is wise!" Pei Chengxian was a close friend of the King of Chu, so he certainly knew how to make this old man happy: "Brother Kuan, you are really amazing. I am convinced! It's just... such a skill... you just said it out loud... what if it leaks..."

"Not true!" His Royal Highness the King of Chu raised his chin proudly upon hearing this: "I am not stupid - the salt and iron business is not something that ordinary people can do - who dares to do this business and not give me face?"

Besides, what His Royal Highness the Prince of Chu was planning to sell was fine salt that was further purified from coarse salt - and what he used as a money tree was the finest refined salt extracted from soy milk.

His Royal Highness the Prince of Chu plans to sell this top-quality refined salt at a higher price than spices - because only in this way can he produce more affordable refined salt so that ordinary people in the Tang Dynasty can also afford it.

It's easy to find people to dry the salt, but the people responsible for refining the crude salt...

Well... King Chu did consider letting his shadow assassins do the hard labor - but he still needed to assign other tasks to these shadow assassins, so His Royal Highness the King of Chu thought about it again and again, and finally decided - it's time to show the style of the King of Chu.

"Your Highness? Your Highness?" - Just when the King of Chu was hesitating whether to plunder Goguryeo or Japan, Wang Xuance suddenly interrupted his thoughts and said, "Are you considering the issue of manpower now? Since this method of drying salt is feasible, we can recruit the people in the fiefdom to help."
