As the treasurer of the Noble Hall, Guo Qingzhu knows too well how terrifying the income of refined salt is.

Even in less than a month, more than a dozen shops have been developed in Dawei.

And if it continues, it won't be long before the noble halls will bloom everywhere.

But now southern Jiangsu wants to make the method of refining refined salt public.

This made Guo Qingzhu a little unacceptable.

"Qingzhu, the situation must do this now."

Looking at Guo Qingzhu's expression, Sunan naturally knew what the latter thought.

Then he said these words with a serious expression.

After all, his primary purpose at present is to help Wei Zifu control the court.

And the imperial examination is the most important step.

Otherwise, Wei Zifu will always be a bare-bones commander.

"I know it too."

"But I'm a little unwilling."

Guo Qingzhu is also well aware of the current situation in southern Jiangsu, but he is still a little reluctant.

After all, the advantage of the noble hall is refined salt.

Therefore, if you hand over the method of refining refined salt, the noble hall will soon be lost to everyone.

"Don't worry."

"Your husband's trick isn't just refined salt."

Looking at Guo Qingzhu, who was depressed in front of him, Sunan directly hugged the latter into his arms.

This made Guo Qingzhu slightly stunned, and showed a confused look when he looked at Sunan.

"Xianggong, don't you ......?"

"In less than half a month, I will research new things."

"At that time, my noble hall will still be the leader."

Sunan pinched Guo Qingzhu's chin dotingly, and then said these words with a confident face.

He's a traverser.

So there are countless future technologies and ruthless work in my head.

And refining refined salt is the least technical thing.

Even if Sunan doesn't say how to refine it, someone else will soon figure it out.

That's why he didn't hesitate to hand over the refining method of refined salt.

"Really?"

The words in his ears attracted Guo Qingzhu deeply, and the curiosity on his face became heavier and heavier.

Seeing this, Sunan nodded heavily.

He ordered someone to buy pork for refining meat oil.

"Xianggong, what are you doing here?"

When Sunan had everything ready, Guo Qingzhu's face was full of confusion.

After all, Sunan made things too weird.

Lard.

Plant ash.

These two things occupy a large area in the backyard of the noble hall, and they look extremely cluttered.

"It's a business opportunity."

Sunan chuckled in response, and began to make soap as he remembered.

Great Wei, science and technology are underdeveloped after all.

So I'm still using the way of pounding clothes to wash clothes.

Sunan, on the other hand, decided to create soap, which is bound to instantly arouse everyone's enthusiasm.

"Does this create a business opportunity?"

After hearing Sunan's explanation, Guo Qingzhu's face showed a look of disbelief.

Even when he looked at Sunan, he was full of suspicion.

After all, what Sunan said was too fantastical, and even made her a little unacceptable.

"That's nature."

Guo Qingzhu's suspicion did not make Sunan dissatisfied.

After all, no one knows about science in Great Wei.

"Look at it."

With the sound of Sunan falling, it is to mix the plant ash and lard together and stir.

After a long time of stirring, the liquid in front of me gradually turned a creamy color.

This made Guo Qingzhu on the side a little dumbfounded.

"It's finished."

"It only needs to sit for a week or two, and the soap is ready to be born."

Looking at the results in front of him, the smile on the corner of Sunan's mouth is getting bigger and bigger.

Even began to look forward to it.

Looking forward to the soap can be popular all over the country.

"Xianggong, even if it can really wash clothes, but this smell ......"

At this moment, Guo Qingzhu already knew what the effect of soap was, but he still maintained a skeptical attitude towards Sunan.

After all, the soap in front of me was filled with the smell of lard.

So I'm afraid it's impossible to be accepted at all.

"It's really a problem."

Under Guo Qingzhu's reminder, Sunan also discovered the disadvantages of refining soap from meat oil.

This made his eyes roll quickly, and he quickly found a solution.

I walked directly to the ornamental flower position on the side.

I picked the ornamental flowers on it.

A meaningful smile appeared on the corner of his mouth.

"Qingzhu, I'll go out."

Sunan looked at the flowers in his hand and said to Guo Qingzhu with a serious face.

The next step was to find the best blacksmith in the capital.

Create a distillation utensil.

"It's a pity that there is no way to completely close it after all."

Looking at the tools created, Sunan couldn't help but say these words with some regret.

After all, this is not a technologically advanced modern age.

So even if the appliance is built, it still can't be completely closed.

So that a lot of steam ran outside.

But Sunan didn't care.

After all, the development of science and technology does not happen overnight, so you can only use the equipment in front of you.

Soon.

He used the evaporation of the petals to extract some essential oils.

But the mixture of petals and water was thrown directly into the meat oil used to make soap.

"How about this time?"

When the soap was re-refined, Sunan invited Guo Qingzhu over as soon as possible.

made Guo Qingzhu's eyes light up.

"Not bad."

"Although the fragrance is a little light, it finally suppresses the taste of meat oil."

Guo Qingzhu spoke slowly, and when he looked at Sunan, he was also full of admiration.

But Sunan waved his palm indifferently.

directly brought Guo Qingzhu to the room.

"Xianggong, what are you going to do?"

Looking at Sunan with an anxious face in front of him, Guo Qingzhu's face showed a shy look.

didn't even dare to look at Sunan.

"I'll give you a gift."

Sunan chuckled and slowly spoke, instantly attracting Guo Qingzhu's attention.

I was also very moved in my heart.

Because since she was with Sunan, this was the first time Sunan wanted to give her a gift.

Her excited appearance made Sunan a little embarrassed.

After all, the gift he brought when he returned from Huizhou last time was cut off by Wei Zifu, so he didn't give anything to the latter.

"I'm sorry."

Sunan spoke slowly, but Guo Qingzhu blocked his mouth with green fingers.

"Xianggong, being able to be your woman is the greatest honor in my life."

"So please don't bother the concubine."

Guo Qingzhu opened his mouth gratefully, and when he looked at Sunan, he was also full of affection.

After all, if it weren't for Sunan, she would still be living on the streets.

If it weren't for Sunan, she would still be bullied by the Guo family.

Therefore, Guo Qingzhu is very satisfied with the status quo.

"In the future, I will be good to you."

Sunan took Guo Qingzhu into his arms, and handed the perfume essential oil that was about to be made to Guo Qingzhu.

This aroused Guo Qingzhu's deep curiosity.

And Sunan also informed Guo Qingzhu of the use of perfume essential oils.

Guo Qingzhu couldn't wait to start wiping it, so that her body exuded a faint fragrance.

"Xianggong, is it fragrant?"

After feeling the change in the taste on his body, Guo Qingzhu asked Sunan with a shy face.

But Sunan licked his lips.

"No matter how fragrant it is, it doesn't smell as good as yours."

After that, Sunan directly picked up Guo Qingzhu and walked straight to the bed.
