Any grease can be used to make soap.

The process of making is not complicated, a large pot, a pot of grease, add caustic soda, and then boil it with fire.

Oils and caustic soda react chemically to produce soap and glycerin.

Pour in a pinch of salt to separate the soap from the glycerin. In the end, you only need to scrape the top layer of sticky paste into the mold box, and after cooling, it will be soap.

The same method can be used to make soap, but the soap needs to be a little more delicate, and colorants and fragrances are added.

The remaining part of glycerin, in this kind of cold and frozen place, can be more suitable for the general public to take care of their skin than water cream or something!

But there is also a problem.

That is, grease was actually a relatively precious thing in ancient times.

It is not ideal to use cooking oil to make nature.

But fortunately, the situation in the town is different.

Most of the people make a living from hunting, and there is relatively no shortage of animal fat. In addition to some practical parts of ancient animal fat, a small part of them were used to make candles.

But in this era, the technology is backward, and even the common people can't afford candles, let alone candles made of animal fat.

Liu Yunyi has the intention to improve the candle, but this problem is a bit out of line for her, and she can study it slowly in the future, and the easiest thing at the moment is to focus on soap making and glycerin refining.

The relevant process can be purchased directly through the system, and the difficulty is low, and it is not difficult to achieve this in Zhenlin, and it is even easier than in the capital.

And once the soap thing is successfully made, it will naturally not worry about sales!

I'm afraid it's not easy to go to the capital, even if the Wang Jiang family is willing to cooperate, the mountains are far away, and the emperor will definitely find a way to interfere.

But one of the advantages of this place is that it is bordered by Xiliang and many small countries in the north, and the small countries are rich, which are all ready-made business opportunities~

The cold wind outside the window still didn't stop, and occasionally wisps of wisps drilled through the cracks in the window, circling around the two of them.

But Liu Yunyi is immersed in his own imagination, when talking about the production of soap and the planning for the future, his spirit is flying, and there seems to be a streamer between his eyebrows. The cold wind had no effect on her in the slightest, no, it should be said that no matter how strong the cold wind was, it could not extinguish her enthusiasm.

Feng Chengqian's favorite thing is her energetic appearance.

I just feel that her whole person is fresh and smart, and people are reluctant to look away.

He was also like her back then, no matter how many troubles and problems he encountered, he was fearless. But in the end, the reality still forced him out of breath, and he could only wear a mask of hypocrisy, and those high-spirited spirits were gradually smoothed out.

Three years have passed, and he has almost forgotten the memories and momentum of that year, if it weren't for her, he might have become more violent and cold-blooded.

But she gave him hope to live well, so that he would no longer be desperate.

Just as she was full of confidence, he couldn't help but raise the corners of his mouth, and he had more hope for the future.

Yunyi, Yunyi, Zhenlin will definitely get better, and you and I can live better......

He swore in his heart.

"This time, do you still need the king's funding?" He asked her with a smile.

Liu Yunyi immediately patted her chest: "The girl has silver this time, not bad money!" ”

What I thought in my heart was that Feng Chengqian had just come to Zhenlin from the capital, even if this was his former territory, but he had not returned for many years, there must be many things to do.

When there is a shortage of silver, I am considerate and considerate of him and does not pick wool.

Besides, compared to relying on others, Liu Yunyi always feels that he is the most comfortable to be the master. At the beginning, she really had no money to ask Feng Chengqian for help, this time she had enough start-up capital, she wanted to be her own boss to make a lot of money and go to the peak of life!

Wow Ka Ka!

Another two days of travel......

Because it has been cold to a certain extent, the temperature has not changed much.

It was all icy and snowy, and if it weren't for the guidance of the army, Liu Yunyi felt that he might not even be able to find a road.

But she's always been able to take pleasure in her suffering.

It's not good to store fresh fruit in the space, so she makes a little bit of jam.

Just dig a bowl of snowflakes from the snow, add a spoonful of honey, a spoonful of jam, stir and mix, and then throw a candied fruit on top to make a special smoothie.

The soldiers never thought that the ice and snow at their fingertips could be used for such purposes, and the taste was very good when you tasted it carefully, and the sweetness could replenish energy, but unfortunately you couldn't eat too much, otherwise your body couldn't stand it.

However, in this way, they have more cordial and respect for Liu Yunyi, the princess.

On the third day, the army finally reached the center of the town.

When Feng Chengqian guarded the frontier, the army was mainly active in the Zhenlin area, and after Feng Zhicheng ascended the throne, he gave Zhenlin to Feng Chengqian as a fief, which was mean and embarrassing in the eyes of others, but he was happy for Feng Chengqian himself.

This is the land he is most familiar with outside of the capital.

And Liu Yunyi was a little surprised, I don't know if the weather is getting warmer, or her illusion, the town is near the central city, but it is warmer than other places, and even the snow is a little thinner.

And after many days of trekking, the terrain finally flattened from mountainous terrain.

When the army arrived at the city gate, they saw the black and black three, as well as a group of generals and countless soldiers at the city gate to greet them.

The leader is that after Feng Chengqian left, he was responsible for replacing Feng Chengqian and was in charge of the deputy general in charge of the town's affairs.

Liu Yunyi poked his head out of the carriage, but saw that the leading lieutenant was very big, looked like five big and three thick, and was wearing a tiger fur, and his face was very fierce, not easy to mess with.

It just so happened that the little general who was in charge of escorting in the past few days rode to the vicinity of the carriage, and Liu Yunyi hurriedly beckoned to him to inquire.

"Who is he?"

"The prince was regarded as a general by the first emperor back then, and this is the deputy general under his command, General Régree!"

"It's really as good as its name suggests." Liu Yunyi chewed on the word Reg, and saw Feng Chengqian getting closer, but Reg still didn't smile, and couldn't help but raise his eyebrows: "This Reg, how is the relationship with the prince?" ”

The little general wanted to remind him that it was not good to call General Lei by his name, but when he thought of the princess in front of him who was the princess who was pampered by the prince in the palm of his hand, he quickly choked back on the words.

"The princess said with a smile, we all fought on the battlefield with the prince back then, and the relationship is good and bad, but if you can be trusted by the prince, nothing else matters, right?"

That seems to make sense.

But Liu Yunyi raised his eyes to look at that day, but he still didn't like it inexplicably.

She was already disgusted with the fierce eyes, but this person still had a strong aura.

Feng Chengqian came in a hurry, this person is good, dressed in style and wealth, more like the master of the town than Feng Chengqian.

Isn't this a disguised show-off?

But just take a closer look, Feng Chengqian's innate nobility and arrogance are not something that can be suppressed by a tiger fur, just a look, he can make people willing to surrender to it.

A lieutenant in a tiger fur? It's just a big and three thick bear.

Hopefully, she's just thinking too much.

With a slight movement in his mind, Liu Yunyi simply jumped out of the sedan chair and ran towards Feng Chengqian's back.

The little general exclaimed: "Princess Niangniang! ”

The voice was quickly left behind by Liu Yunyi, but the sudden appearance of a woman in the army was undoubtedly eye-catching, and everyone watched Liu Yunyi trot all the way to Feng Chengqian's side.

Feng Chengqian happened to dismount and stood firm in place, and when she pounced, he grabbed her waist to prevent her from slipping in the snow.

"How can you be so reckless?" Feng Chengqian flicked the fine snowflakes on her hair.

Liu Yunyi shook his head, and said in a sweet tone: "Didn't the prince say that he wanted to take me home, I want to take a good look at the scenery of the town with the prince." ”

As he spoke, the man snuggled up to him, but his eyes glanced at the soldiers opposite.

Feng Chengqian was slightly stunned, and instantly saw through Liu Yunyi's careful thoughts, and suddenly couldn't help laughing.

"In that case, then follow the king into the city!"

The deputy general Lei opened his mouth at the right time: "I heard the name of the princess Niangniang, but today I saw that it really captivated the country and the city, and the talented woman of the prince is like glue!" It's really envious of my subordinates! ”

The other little generals also smiled and agreed, saying that the prince was naturally blessed, and the princess was beautiful.

Liu Yunyi heard goosebumps, although he knew that he was going to enter the city today, and deliberately dressed up so as not to embarrass Feng Chengqian, but the description of the country and the city is too exaggerated, exaggerated to the point of being a bit hypocritical.

Naturally, there is no show on the face.

exchanged a look with Feng Chengqian, and accidentally caught Feng Chengqian's eyes flashing with a hint of unhappiness.

Without saying much, the two got on the horse again, Feng Chengqian took her in his arms and rode a horse, all the soldiers immediately cheered to give way, and Feng Chengqian led a group of soldiers behind him into the city.

The people in the city also knew early that their king was about to return today, and it was natural that they would welcome something.

From the moment the two entered the city, the cheers directly drowned out their hearing.

Although the sides of the street were still wrapped in cold colors, they were crowded with countless people, reflecting the smiling faces of red and full of enthusiasm and joy.

There is no need for tiger fur, no need for decoration, but there are still countless people who recognize Feng Chengqian on horseback at a glance, and they are crazy about it in an instant.

"King Cheng has finally returned to the town!"

"The prince is back!"

Such joys are endless.

Feng Chengqian also rarely showed a slight smile and nodded at them.

"This king is back!"

In just five words, the cheers were easily pushed to another climax, and the enthusiasm of the people was about to overturn the entire city!

I don't know how long it took to finally walk through the modest streets, and with the soldiers opening the way, all the way to the fortress in the center of the city.

That's right, due to the weather restrictions, Feng Chengqian's residence was not a mansion in the capital, but a stronger fortress that could withstand the cold.

General Lei, who had just fallen behind the team, rushed over to open the way in person at some point, and Hei Da and Hei San placed the wounded soldiers.

"The prince has worked the road, and his subordinates have already ordered someone to prepare wine and food, just waiting for the prince to come back." After General Lei finished speaking with a smile, he only remembered that there was another Liu Yunyi, and hurriedly added: "There is also the princess Niangniang." ”

Feng Chengqian's footsteps to the threshold paused slightly, looked at him, and smiled: "It's hard for you." ”

"What the prince said is as it should be, how can it be hard or not!"

The other soldiers also echoed one after another, smiling and grinning, and the atmosphere was very harmonious.

is different from the one board and one glance at the city gate, and now there is no sight of others, and everyone's attitude towards Feng Chengqian is more friendly in addition to being respectful.
