I'm a useless prince, so what if I know a little bit of chemistry?

After a few days of understanding, Lin Fan has discovered that nowadays, everyone uses soap nuts to wash clothes and hair.

The degreasing ability of soap nuts is limited, but it is okay for washing clothes. If you rub it vigorously or wash it several times, it can still be relatively clean.

If you use soapnuts to wash your hair, it is indeed a bit difficult.

Not only is it not very clean after washing, but it also has an unpleasant smell.

Therefore, Lin Fan wanted to make soap first.

The first thing is, of course, to give yourself priority and make it cleaner and more comfortable.

The second is that it can be sold for money.

In today's Liang State, soap is used to wash clothes and hair more cleanly, unlike the soap in the past.

Crush some petals into juice and add the juice to preserve the fragrance.

Who wouldn’t like something so useful and nice smelling?

It is definitely an extremely huge market.

Lin Fan naturally would not give up.

"What exactly is Your Highness going to do?" Chun Fang was curious and followed behind Lin Fan, wanting to take a look.

Lin Fan did not explain further.

In modern times, soap is an extremely common item, and in this era, it would be extremely difficult to explain without the corresponding understanding.

"Making soap." Lin Fan said without turning his head.

Soap?

Is it a fat soapberry?

But soap beans are neither humans nor animals and cannot eat anything, so how can they get fat?

Lin Fan was unaware of Chun Fang's naive thoughts, but recalled the method of making soap.

The appearance of soap in history was actually quite accidental.

If Lin Fan remembered correctly, there was an apprentice blacksmith who accidentally spilled grease into a fire that had just been extinguished while working.

For fear that the burning grease would cause a fire, they covered it with a layer of ash.

When the apprentice washed his hands, he found that the grease that was originally difficult to wash off was now washed away extraordinarily smoothly, and there was a layer of foam on his hands.

Later, the apprentice discovered that the grease covered by the ash had solidified into lumps with strong cleaning ability.

By chance, soap appeared.

It’s actually very simple. Wood ash is alkaline, and it reacts with oil to form soap.

Lin Fan first put the melted lard into the prepared mold, then sprinkled in wood ash, and then sprinkled in some crushed flower petals.

"Alright." Lin Fan said calmly.

"Is that enough? But I haven't seen any soap beans, so how can they get fat?" Chun Fang was amazed and stared at Lin Fan in a daze.

"Don't worry, you'll naturally like it after it's done." Lin Fan didn't tell Chun Fang directly, but kept him in suspense.

"like?"

Chun Fang looked at the lard and the layer of dust and shook his head.

If it weren't for His Highness's order, she would not touch these things.

"Yes, Chunfang will definitely like it." Chunfang finally said something against his will. After all, it was made by His Highness himself. If he said he didn't like it, it would definitely undermine His Highness' confidence.

Lin Fan naturally saw through Chun Fang's insincerity. After all, the little girl couldn't keep things in her heart.

Just wait for the soap to be ready, and I'm sure Chunfang will love it.

But we still have to wait a little longer, as the results will not be seen for a while.

In the evening, Lin Fan did not ask the cook to prepare dinner.

Instead, he prepared a variety of ingredients and a pot.

Although he now has stir-fried dishes, the taste is always inferior to what Lin Fan remembers because of the seasoning.

So Lin Fan planned to try hot pot. Of course, because there was no chili, Lin Fan could only make a three-fresh hot pot.

"Your Highness actually knows how to cook?" Chun Fang was very surprised.

After all, I have been with Lin Fan for such a long time, but I have never seen or known this.

"Perhaps it is only after His Highness' mind became clear that he has such thoughts."

Chun Fang comforted herself that in her opinion, Lin Fan was just a stew, even though the pot had changed.

After everything was ready, Lin Fan asked Chun Fang to invite Nian Gui so that the family could have a meal together.

When Nian Gui heard that Lin Fan wanted to treat him to a meal, he was surprised for a moment, but then he smiled with relief.

"Fan'er has finally grown up, sister, have you seen it too?"

Nian Gui and Lin Fan's mother Nian Jiao did not expect Lin Fan to achieve much in the future, after all, he was a little stupid when he was born.

I just hope that Lin Fan can live a healthy and peaceful life, which is also the origin of his name Lin Fan.

Nian Gui changed into casual clothes, wearing a refined official coat inside and a hero cloak outside. If an ordinary person wore this, it would naturally look out of place.

But on Nian Gui, it doesn't seem out of place at all, and it even makes people feel that it should be that way.

The Imperial City is located in the center of the capital, covers a large area, and is where the royal family lives.

The Imperial Palace is located in the center of the Imperial City and also the center of the capital.

At this time, one naturally cannot enter the palace unless summoned by Emperor Liang.

But within the imperial city, no one dared to stop him because of his noble status.

After entering the prince's palace and looking at the words on the plaque, Nian Gui felt dazed for a moment.

The last time I came here was eight years ago.

The family was still reunited at that time, but now everything has changed.

"uncle!"

Lin Fan greeted him outside the door. Seeing Nian Gui staring at the plaque in a daze, he knew that Nian Gui was thinking about something sad, so he called him affectionately.

"Fan'er, why did you think of inviting your uncle to dinner today?" Nian Gui smiled and patted Lin Fan's head, as if he was caressing a child.

"Uncle, I'm not a child anymore." Lin Fan said happily.

"Hahaha, in my uncle's eyes, you have always been that." Nian Gui was not angry and pulled Lin Fan into the mansion.

"Hello, Master." Chunfang greeted him respectfully.

"Yeah." Nian Guiqing responded.

"Fan'er, what are you planning to treat your uncle to today? I'm hungry. If it doesn't taste good, I won't eat it." Nian Gui joked with a smile.

"That's a difficult problem. My uncle has seen all kinds of delicacies from land and sea. I'm afraid he can't get used to the simple meals here." Lin Fan said with a smile.

"Hahaha! Stop talking nonsense. Uncle is really hungry." Nian Gui said.

"Okay, it will be ready soon." Lin Fan asked the two cooks to move all the things out and put them in the yard.

Lin Fan simply taught Nian Gui how to eat it.

Nian Gui was surprised and said, "Is that so? It is somewhat similar to the war."

Every time they won a battle or to encourage their soldiers, they would kill pigs and sheep. Most of the time, they would be cooked in a big pot and everyone would get a piece of them.

Nian Gui thought that the taste was just average, but after taking a bite, it was like discovering a new world.

“Delicious, really delicious.”

"Try it, this is delicious too." Lin Fan put a piece of cooked tripe into Nian Gui's bowl.

In just a few moments, most of the food on the table was cleared away.

"Yes, if we run a restaurant this way, I'm sure we'll make a lot of money." Nian Gui burped.

At this time, the sky was already dark and the two of them lay in the shade of a tree to enjoy the cool air.

"Your Highness, what you want has been made."

Hearing Xiang Long's voice, Lin Fan excitedly said to Nian Gui: "Uncle, the treasure I mentioned that can improve the strength of the cavalry is already ready."
