After swapping bodies with the princess, this prince slaughtered his way through the court and becam

After the lime and wood ash arrived.

Ren Jingxing first had the workers soak each of the two ingredients in a small bowl.

After the bitter salt solution has been boiled down to produce some crystals.

Ren Jingxing then demanded that the matter be stopped.

"You must remember the following steps!"

When boiling bitter brine, stop boiling once a tiny bit of salt has been extracted.

Then slowly pour the clear limewater into the bitter salt water.

Ren Jingxing demonstrated and explained to the workers at the same time.

After Ren Jingxing poured the lime water into the bitter salt water.

The bitter salt water that had been filtered clean actually started to precipitate impurities again!

"See these white things? That's the poison in the bitter salt!"

The workers who were watching were shocked.

They all opened their eyes wide and their mouths agape, staring at each other.

"There really is something there!"

"Could it be that the young master really knows how to handle refined salt?"

The workers are all pragmatic.

When they discovered that Ren Jingxing seemed to actually be able to purify refined salt, their attitudes immediately changed.

"Young Master, what's next?"

"Young Master, how much lime water should I pour?"

Sensing the changes in the workers around him, Ren Jingxing smiled.

What these workers admire most is genuine skill.

As long as he comes up with a solution, he won't have to worry about the workers not trusting him.

"When pouring lime water, you should stir it at the same time."

The workers watched Ren Jingxing's movements carefully and listened attentively to his explanations, afraid of missing any details.

"Wait until no more white impurities appear!"

Pour in the clarified wood ash water again until no new impurities appear!

The workers witnessed firsthand that when pouring lime water no longer produced impurities, pouring in wood ash water resulted in new impurities appearing!

Now they truly understood; the young master really did have something!

The workers immediately became excited.

The prices of bitter salt and refined salt are worlds apart.

If they really mastered the technique of extracting refined salt from bitter salt.

Then their useless salt mountain will become a gold mountain! A silver mountain!

The workers' attitude towards Ren Jingxing immediately became extremely subservient.

"Young Master, what should we do next?"

"Young Master, is the remaining water now the refined salt water?"

"Young Master, are you tired? Would you like me to get you a stool?"

"Young Master, are you thirsty?"

Shen Shumin, standing behind the workers, was stunned.

What's going on?

This spoiled young master won over the workers by pouring them two bowls of water?

Ren Jingxing waved his hand and continued:

"Not yet. There is still some bitter salt in the salt water, but it's much less now."

At this point, take out a clean strip of cloth and hang it on the bucket to continue cooking!

Boil until the cloth strips are completely soaked in salt; at this point, the salt on the cloth strips is all refined salt!

The workers are now very enthusiastic.

They quickly found a clean cloth, hung it directly on the pot, and continued cooking.

This bitter salt water is actually a saturated salt water solution that has been boiled.

In addition, the use of wood ash water and lime water removed most of the impurities that were prone to settling.

At this point, a slight heating will cause recrystallized particles to precipitate out.

And all of this salt must be refined salt!

After a moment, a worker pointed at the cloth and shouted:

"Look, salt, white refined salt!"

However, the workers did not start working; instead, they turned around and looked longingly at Ren Jingxing.

Now, in the workers' eyes, what Ren Jingxing said is right.

Boil it for a while longer, until the cloth strips are covered with salt, then remove it.

"So tired!"

After the cloth strips were soaked in salt, the workers took them out and carefully scooped the salt into a clean bowl.

At this moment, the workers looked at each other.

"How so? Who wants to try it first?"

"Let me taste it; I can tell if it's refined salt!"

A gaunt old man walked up to the bowl, carefully dipped his hand in the salt, and then put it in his mouth.

The old man's eyes lit up at first, then he showed a regretful expression, and then he slapped his thigh hard.

"oops!"

The old man's commotion left the workers looking at each other in bewilderment.

Even Shen Shumin, who had never been optimistic about Ren Jingxing, couldn't help but feel anxious.

Is it still bitter salt?

"What's wrong? Old man, say something!"

"Yeah, what's with that expression!"

At this moment, Old Man Zhu, who was tasting the salt, sighed:

"Ah, this is refined salt that is comparable to tribute salt!"

That one bite of mine probably cost me an ounce of silver!

Upon hearing Ren Jingxing's method, they were able to extract refined salt comparable to tribute salt from bitter salt.

Zhuangzi's workers are going crazy.

"That's amazing! That's amazing!"

"God has finally opened his eyes!"

"What does this have to do with God? This was brought by our young master!"

"Thank you, Your Highness!"

The workers immediately kowtowed to Ren Jingxing.

Shen Shumin stared blankly at Ren Jingxing, who stood tall and straight.

Is this spoiled young master really capable?

The Marquis of Xuanwei's household has made a fortune by being able to turn bitter salt into refined salt.

At that time, just a sip of leftover soup from Xuanwei Prefecture will be enough to make the whole manor eat until their mouths are greasy!

Shen Shumin's initial disdain for Ren Jingxing's doubts eventually turned into admiration and embarrassment.

So the young master is this amazing.

But I didn't believe him just now, and I was even criticizing him in my heart.

They even had someone report the news to the Marquis...

Thinking of this, Shen Shumin was startled.

No, we have to get the person who went to tip them off back right away!

Just then, a loud shout suddenly rang out from the south.

"Ren Jingxing! What have you done now?!"

Ren Hou's voice suddenly rang out.

Everyone around knelt down at once.

"Greetings, Your Excellency!"

Ren Hou's face turned red, and he was holding a wooden stick in his hand.

"You've only been behaving for ten days! Ten days!"

You can't even pass the county-level exam?!

Ren Hou was so angry he felt like his lungs were about to explode.

He was already worried about his son's sudden loss of interest in studying.

Suddenly, Zhuangzi sent a message.

His own scoundrel son had actually swindled the other princes out of their money to buy his family's bitter salt mine.

They even came up with some ridiculous reason about extracting refined salt!

Is he trying to force Marquis Xuanwei to sever his ties with the court and his noble lineage?

If Ren Jingxing had continued to be such a spoiled brat, that would have been fine.

But did he suddenly give the family hope only to plunge them into despair again?

Ren Hou even felt somewhat wronged.

Ren Jingxing was stunned by the scolding.

He kindly helped the Ren family supplement their household income, so why was he suddenly scolded?

And how did his father find out?

He wanted to give his dad a surprise.

At this moment, Shen Shumin approached Ren Hou with a conflicted expression.

When Ren Hou looked at Shen Shumin, he forced a kind expression onto his face.

"Shumin, we owe you a lot this time."

Otherwise, I have no idea what kind of disaster this brat could have caused!

Shen Shumin was so embarrassed she almost cried:

"My lord, no, that's not it..."

The Crown Prince has brought out the refined salt!

Ren Hou was taken aback at first, then his expression turned serious:

"Did this little brat threaten you?"
