The Three Spirit Stones

At dinner time, neither Ah Cai nor Cheng Yu went to the side hall. Dong Mei went over to tell Madam Cheng that the prince and the young lady were too busy to come to dinner.

When Sun Yuechan heard this, she felt very upset. She thought Cheng Yu must be blaming her for scolding him mercilessly today, so he didn't even come to eat.

This is unfair to him. How can a man who has lived for a thousand years be so narrow-minded?

He is really busy. To be precise, it is Acai who is busy. She is writing furiously now!

Over the years, all her study materials were stored in a folder on her phone.

This phone was previously taken away by Cheng Yu because he found out that A Cai brought the power bank back to play games. He thought that this phone would be of great use in the future, so how could he use up the battery just to let her play games?

So he confiscated the phone despite her protests, and then the maids in the yard saw the prince and the young lady quarreling over a chicken.

Now she had to race against time to copy down all the knowledge points learned in these years before the battery ran out, otherwise she wouldn’t be able to remember them all by relying on her brain alone!

……

"Now you understand my foresight, right? Fortunately, I didn't let you use up all the battery playing games. Don't you understand what's so fun about this crappy game?"

Cheng Yu fed her and scolded her at the same time.

Ah Cai didn't say anything. She didn't have time to deal with him.

"Open your mouth,"

He stuffed a mouthful of rice into her mouth. Because he had to save time, he cooked a little food in the small kitchen.

When it was evening, Xia He lit five or six tallow candles to illuminate the study.

I copied until the middle of the night, I changed the candles several times, and used the power bank one after another.

Finally, the phone made a buzzing sound and the screen went off forever!

Relying on her memory, Ah Cai copied down the last chapter, filling up two large notebooks, which were densely filled with various English letters, symbols and formulas that looked like hieroglyphics.

After copying, her hand holding the pen was so stiff that it was shaking. Cheng Yu massaged her arm with concern, and it took a while for the blood circulation to resume.

"Ah! I've finally finished copying it! I've finally finished copying it!"

She was so excited that she cried and laughed, just like when she was a kid on summer vacation, she remembered she had a lot of homework to do the day before school, and finally rushed to finish it.

"Okay, I've finally finished copying, I can take a break now,"

Cheng Yu also breathed a sigh of relief and was about to carry her back to the bedroom to rest.

"I'm so happy that I finally finished copying. I thought I wouldn't be able to finish it! Ba Ba..."

Ah Cai happily hugged his neck and kissed his face non-stop.

Ouch! I can't bear it anymore.

He was so excited by the kiss that he was burning with desire. When he was thinking about having sex in bed to celebrate, the person in his arms had already fallen asleep.

……

……

The number one project to make a fortune through time travel…soap!

Soap is very simple, it is the saponification reaction of caustic soda and oil. Caustic soda is sodium hydroxide. There are natural caustic soda mines in Tongbai County, Henan Province, and there is also caustic soda in Zhangjiakou area.

Cheng Yu sent people to purchase a large truckload of raw materials, rented a bungalow on the outskirts of the city, and made the first batch of finished soap a month later according to the recipe given by A Cai.

Sun Yuechan was surprised after trying the soaps.

She keenly realized that the sales prospects of this soap were limitless.

On the busy Nanxunmen Street, there is a shop with several tables in front of it, which are piled with square objects.

There was a big banner hanging on the door of the shop with a few big words on it: Wash your clothes, wash your hands and take a bath, and you will be clean in one wash! The banner next to it said, "Good and cheap, soap is on sale!"

Two men were shouting at the door, performing the same trick of washing clothes with soap.

"I have worn this dress for seven days, smell it,"

One of them gave another a piece of clothing with obvious stains to smell.

The man sniffed it and began to dry heave exaggeratedly, pinching his nose and pretending to be angry and said, "It stinks so bad? Are you trying to suffocate me to death?"

"Give it to me, I'll wash it for you."

He grabbed the dirty clothes, put it in the basin in front of him, rubbed it with soap a few times, rubbed it for a while and rinsed it with water. The clothes were immediately as clean as new!

"So amazing? What about this one?"

The man took off his clothes in a flash, revealing his muscular body, and clenched his fists to shake his chest muscles.

The audience burst into laughter, and the laughter attracted more people to come and watch.

"If you wash my clothes, you win."

After saying that, he threw the clothes he had taken off over to me. This one was obviously dirtier than the previous one. The man rubbed it with soap and then rinsed it with water.

Wow! It's as white as new!

With such an intuitive performance, the effect is clear at a glance, and then the two of them sing in unison!

How much? Four hundred dollars! Buy three pieces, one hundred dollars.

In fact, in the Northern Song Dynasty, one dou of rice could be bought for five coins.

To clean clothes, ordinary people mostly use plant ash, and 400 yuan for a bar of soap is a sky-high price.

But that soap costs almost ten taels of silver a piece. In comparison, this soap has a very high cost-effectiveness!

There were too many rich people in Bianjing City, and three pieces of silver were only one tael, so many people could afford it.

Not only that, Sun Yuechan also had a batch of mahogany boxes made, each box contained nine bars of soap, with the words "Long, Long, Long" engraved on them. These soaps were red in color and were specially used as gifts for weddings. Naturally, the price was several times higher than ordinary ones.

For a time, this [Cheng's Daily Necessities Shop] was crowded with people and made a lot of money every day.

In the office on the second floor, Cheng Yu and Sun Yuechan stood in front of the window to observe the trading situation below.

"Where did you invite these two people?"

Cheng Yu looked at the two actors performing laundry and asked,

"We hired storytellers from the tile shop, 20 taels a day per person," said Sun Yuechan.

"...Hey! A little clever,"

Cheng Yu said with a smile, turned back to the table and sat down to take a sip of tea.

Is this a compliment or an insult to me?

Sun Yuechan had been working with him for a while, and they had become more familiar with each other, and they were no longer as polite and distant as before.

"I am a little smart, ... then you, Acai, are very smart?"

She teased and sat back at the table.

What do you mean by smart? You are the smart one. This woman has a mean tongue!

Cheng Yu rolled his eyes at her and said, "My Ah Cai is not very smart, she is a genius."

"You will gradually learn about my ability. The world will change because of her."

"Okay! I'll wait and see,"

"Hmph~"

After a few words of bickering, Cheng Yu said, "Yuechan," but he was too lazy to add the word "sister" now.

"Do you know martial arts?"

"Who told you? ...Mother?"

"Um!"

He hummed vaguely.

In fact, he had long seen that Sun Yuechan knew martial arts, because people who knew martial arts walked, lay down, and sat differently from ordinary people, and if one looked closely, they would also find that their meridians and bones were different.

"My father is a general. We, the children of generals, have been practicing martial arts since we were young. When I was just an adult, I dressed up as a man and went to the border and the battlefield with other brothers!"

"Oh! So amazing?"

Cheng Yu said this from the bottom of his heart.

The fact that a woman can go to the battlefield, regardless of whether she has ever fought against the enemy, her courage alone is worthy of admiration.

"Thank you for the compliment!"

Yuechan glanced at him proudly and said, "Why are you suddenly asking me if I know martial arts? So what if I know? So what if I don't?"

"It's like this. I may be busier and busier in the future. Please take good care of Ah Cai when I'm not at home."

"She doesn't understand a lot of things. If she wants to go out, please follow her and protect her. With you by her side, I feel more at ease when I'm out doing things!"

Oh! So that's how it is! Yuechan understood.

"Don't worry, I will take care of her when you are out."

Cheng Yu was very pleased to get her promise. He stood up and bowed to her. She didn't expect him to be so serious, so she returned the greeting.

I couldn't help but sigh in my heart!

He really loved her to his core.

It seems that Acai is not as useless as she seems. At the very least, it is not easy for her to make soap!
