After the mistress of the Marquis' Mansion was reborn, she divorced and married the prince!

Song Yanzhou hesitated for a long time, but couldn't help but speak.

"I don't mean to hit you... You know the process of making animal fur is very complicated, right?

“If the fur is not tanned properly, it will become hard, shrink and lose hair.

“Not only does it look terrible, but it also doesn’t provide much warmth… If you can make one fine piece out of ten furs, you’re a master craftsman!”

Song Mingli tilted his head.

Song Yanzhou thought she didn't understand the situation.

"That is to say, the fur business has high costs and great risks..."

"What if I know how to make saltpeter?" Song Mingli said calmly.

"Huh?" Song Yanzhou was slightly stunned.

Song Mingli is not bragging.

In her previous life, in order to help the Marquis's Mansion make money, she couldn't just rely on her dowry.

Although her dowry was generous, with so many people in the mansion, it would eventually be spent.

Sometimes, you have to push yourself to realize your potential.

She was a delicate flower who was raised and cared for by her parents and brothers.

But in her husband's family, she had to roll up her sleeves and do many things herself.

She tried many businesses, including tanning furs.

She devoted herself to asking the masters for advice, bought some things herself, raised rabbits and raccoon dogs, and conducted repeated experiments for two years.

God helps those who work hard, and she finally figured out an effective solution.

The fur she tanned was soft, smooth, and did not shrink or shed, and her success rate was 80 to 90 percent.

Later, "Gujia Fur" became popular in Kyoto.

It became a hot commodity that the nobles rushed to buy, and also made a lot of money for the Gu family...

In this life, the Gu family can forget about it!

If she has money, of course she wants to make it with someone who truly cares about her!

"Even if you know how to make nitrate, you can't go to the northwest, right?"

Song Yanzhou said helplessly, "The fur must be nitrated before it can be transported over long distances, otherwise it will stink and rot on the way."

Song Mingli nodded, "So, we need our trusted people in the caravan.

"It would be even better if we could establish a stable supplier or workshop in the northwest."

Song Yanzhou stared at Song Mingli with wide eyes.

Is she serious? Not just acting on a whim?

“Oh, you…you…”

Song Yanzhou stuttered for a moment, wanting to say that she was daydreaming, but afraid of discouraging her.

I just said that you should trust her.

"Let's not talk about fur for now, what is cotton?" Song Yanzhou frowned.

"Ah?" Song Mingli was also confused.

Brother, don’t you know cotton?

Oh... Song Mingli knocked her head, she had mixed it up.

Cotton was a crop brought back by the generals who went out to the frontier a few years later.

It would take several years before cotton was widely planted in Beili!

Nowadays, there is a poem saying: "In late autumn, I picked reed flowers and put them in my quilt."

Nowadays, people still use cloth, poplar and willow catkins, as well as reeds to make quilts and cotton-padded clothes.

These fluffs are free of charge and people can pick them at will.

But there are too many monks and too little porridge, and these fluffs are difficult to collect.

It often takes a long time to save enough money for a winter coat.

Those with better conditions would accumulate feathers from livestock, but raising many poultry requires a wealthy family.

"It is a plant. The cotton flower has a large amount of fluff, which is higher than willow and poplar fluff. It has a good warmth-keeping effect! It is suitable for making quilts and cotton-padded clothes, and has an excellent cold-proof effect!"

Song Mingli said seriously, "I can draw its appearance, and then ask the caravans heading west to keep an eye out for this plant.

"Cotton is harvested in the fall, or a little earlier. Let a caravan harvest the cotton and bring it back. We can try to make a piece of cotton clothes and quilts."

Song Yanzhou looked at his younger sister in astonishment, with a look of disbelief.

He asked tentatively, "Have you ever seen cotton? Where?"

Song Mingli coughed lightly, lowered his eyes, and looked sad.

"Before I got married, my father gave me a notebook that he had written down during his military campaigns.

“I told my father that I had never seen the beautiful scenery outside the courtyard, and I envied the freedom of men.

"Dad wrote the note himself and gave it to me."

Song Mingli took a deep breath and tried hard to hold back the tears that were about to burst out.

Song Yanzhou also straightened his back and held his breath, "Daddy's notes..."

"Unfortunately, last time, Prince Gu broke into my warehouse by smashing my door lock...

"The notebook was lost."

Song Mingli's voice was low and nasal.

Song Yanzhou stood up suddenly, his face dark and anger swirling in his eyes.

"When I first checked, I only paid attention to the big items and didn't pay attention to things like notes...

"Later, I found out it was lost, but it was too late. After all, it wasn't valuable, so the government wouldn't care."

Song Mingli sighed, "It's my fault for not taking good care of it. I hope Daddy won't blame me..."

Song Yanzhou clenched his fists, and veins were faintly visible on his forehead.

"I see... In other words, you saw the information about cotton and fur nitration from Daddy's notes?"

Song Mingli blinked...Hmm?

She only said cotton!

As for tanning furs, she hasn't figured out how to explain it yet.

Since big brother said so, then let’s say so.

"In that case, you are very thoughtful."

Song Yanzhou took a deep breath, calmed himself down and sat down again.

"Whether it's the secret method of tanning fur or harvesting cotton, we need someone we can trust to go there..."

"Oh my god!" Song Yunqi suddenly jumped in from outside the door.

He had been eavesdropping outside since some point, and when he heard this, he finally couldn't help it and stuck his head out.

Song Yunqi patted his chest and said, "Is there any 'confidant' more reliable than me?

"You two are so mean! You actually discussed such a thing behind my back! That's too much!"

As Song Yunqi spoke, he made a face at Song Mingli.

"It would be best if Second Brother could lead the team."

Song Mingli frowned and said, "It's just... Can the Song family leave Beijing?"

The light on Song Yunqi's face dimmed instantly after hearing these words.

"Ah... that's all I said..."

The young man slumped dejectedly in his chair.

Song Mingli and his elder brother looked at each other and she whispered.

“Being confined to Kyoto all the time, unable to do this or that, will make you useless.

"Second brother is young and full of energy. It's time for him to go out and explore, endure hardships, and gain experience..."

Without experience, how can one become successful?

Song Mingli has her own selfish desire. She hopes that her two older brothers can grow through experience and become independent and capable people.

In the future, even if she encounters any accident, her two brothers will be able to help her take care of Jingyou, right?

"This matter...is not completely impossible."

Song Yanzhou pondered and said, "Everything depends on human effort!"

"Brother!" Song Yunqi sat up straight in an instant.

He was as excited as if he had been injected with chicken blood, "Then I disguise myself and sneak out of the capital?"

Song Yanzhou rolled his eyes at him.

"If we are discovered, it will be a crime of deceiving the emperor. Do you want your whole family to be convicted?"

Song Yunqi shrank his neck in dismay and muttered, "You were the one who said that everything depends on human effort..."

"I'll figure out a way to deal with this matter."

Song Yanzhou said confidently, and he looked at Song Mingli again.

"Mingli, write down everything in Daddy's note about the appearance, characteristics, and usage of cotton."

Song Mingli nodded, "Okay, prepare the writing brush and ink. Although the notebook is lost, I have memorized it in my heart."

Dad, I'm sorry, I'm using you as a cover again!

"What about me? What should I do?" Song Yunqi looked at the two of them and asked anxiously.

"you……"

"I'll tell my second brother the secret recipe for nitre-treated fur. Go buy some rabbits to try it out. It would be great if we could master the secret recipe before leaving Beijing!" Song Mingli said with a smile.

Song Yunqi's face immediately lit up and he became more energetic.

"Okay! Don't worry, my second brother won't let you down!"
