The Queen of Qing Dynasty is beautiful and kind

Chapter 66
In the next few days, because Yinzhen went to and from the Imperial College to study every day, everything in the fourth elder brother's mansion was safe and sound, and nothing happened.

Under the guidance of Nanny Zhuang, Gu Qinghuan and Yaqi became more and more comfortable in managing the affairs of the mansion, and everything went smoothly.

At the end of February, the weather is getting warmer.After taking off his winter coat, Gu Qinghuan felt refreshed.

In the evening, the concierge said that Zhuangzi had sent fresh melons, fruits and vegetables, so Gu Qinghuan hurriedly led Yaqi over to inspect them.

They are all seasonal vegetables and a basket of red cherries.

"There are cherries!"

Yaqi watched the boys move things into the kitchen, staring straight at the basket of cherries, as if a hungry wolf saw a lamb and wanted to pounce on it immediately.

"Don't be too obvious..."

Gu Qinghuan hastily reminded Yaqi that she regained her composure.

"I know!" Yaqi stuck out her tongue, but she still salivated at the basket of cherries.

Two quarters of an hour later, all the vegetables and fruits were moved into the kitchen, and Gu Qinghuan went to pick up a basket of cherries, saying that they were going to wash them at night and give them to the fourth elder brother.

At the edge of the well, Yaqi worked hard to get a bucket of water out of it, and accompanied Gu Qing to happily wash the cherries.

"It shouldn't be a problem if I steal a few?"

Yaqi looked around and found that there was no one there, so she stuffed four or five cherries into her mouth.

"So sweet!"

Before she had time to eat the cherries, Yaqi sighed vaguely: "It's good to be the master, you can eat anything rare."

As soon as she finished speaking, Yaqi spit out the cherry seeds, wrapped them in a handkerchief and put them in her palm.

"Qing Huan."

Yaqi poked Gu Qinghuan, and asked: "You said, if I bury these seeds in the soil, will they grow out in a few years, so we won't have to suffer so much haha."

"... "

However, Gu Qinghuan shook her head and said, "I think...it shouldn't be possible."

"why?"

Yaqi hurriedly asked: "Isn't this how seeds are buried in the soil and then germinate?"

"I don't know either. But... it shouldn't be possible." After Gu Qinghuan finished speaking, she tilted her head and remembered a long time ago.

In junior high school, a boy liked her.

She didn't know it herself, she had heard it from others.

At that time, there was a cherry tree in the school. When it was fruiting in spring, the boys ran to pick the cherries secretly, but the dean discovered it.

He ran away like flying, came to her, and gave her the little cherry.

Gu Qinghuan was very happy at the time, so happy that she immediately went home and buried the cherries in the soil, hoping that the cherries would take root and sprout and grow into cherry trees, so that they could eat cherries.

While her focus was a bit different,...she also remembered that the cherries in the soil ended up rotting and didn't sprout.

"Then you won't be able to eat cherries from now on..."

Yaqi felt a little sad when she heard that, and sighed: "Forget it, let's wait until next time, and eat a little more."

"Ah."

Gu Qinghuan agreed with a bit of dejection, and went to the small kitchen with Yaqi to check on the dinner.

On this day, it was a little late for Yinzhen to return home.

Gu Qinghuan was so hungry that he waited, looking at the braised pork that was still hot on the pot, he even had the idea of ​​wanting to eat it himself, without waiting for Yinzhen to come back.

But well...

Fortunately, Yin Zhen came back.

"Set the meal." After Su Peisheng ordered, Gu Qinghuan and Yaqi hurriedly led the little maids to set the meal.

In the dining hall, Yinzhen was sitting upright, frowning in a daze.With a straight face, I don't know if I am in a bad mood.

Gu Qinghuan didn't dare to vent his breath immediately, and just watched from the side.

Fortunately, everything went smoothly when Yinzhen was eating, and nothing went wrong.

When the sky was dark, Gu Qinghuan had just eaten, and when he passed by Yinzhen's house, he saw Yinzhen who was reading a book through the half-open window.

He was sitting in front of the table, looking at the book in front of him seriously, looking like a good student.

"It's hard work."

As Gu Qinghuan thought about it, a gust of warm wind blew past behind him, moving the windows slightly.

Yinzhen's thoughts were interrupted a little, when he was about to close the window, he saw Gu Qinghuan who was standing outside looking at him.

"Why are you standing outside?"

Yinzhen frowned and said, "Come in and close the window for me."

"... "

Gu Qinghuan was silent, and said in his heart: "You get up and close the window by yourself, isn't it faster than me going in and closing the window for you?"

Gu Qinghuan, who was too blunt, entered the house very reluctantly, and helped Yinzhen close the window.

During the whole process, Yinzhen didn't lift his eyelids, he was still sitting upright, looking at the book in front of him.

Gu Qinghuan was a little curious.

She has also seen Yinzhen reading books before, although they are very serious, but never like this, reading for a long time without turning the pages.

Finally, driven by curiosity, Gu Qinghuan stretched his neck and glanced at Yinzhen.

With just one glance, Gu Qinghuan was stunned.

Why is Yinzhen reading a book here?Obviously doing a question.

Moreover, it is a math problem.

This math problem is still a geometry that Gu Qinghuan is very familiar with.Several triangles merge together on the picture, which looks a little messy.

Yinzhen was scratching his head, obviously he couldn't do it.

The corners of Gu Qinghuan's mouth twitched, suddenly he felt a little better.

She is not a top student, but she is not bad at math, especially geometry problems, where she basically got full marks in the past.

"What is the fourth elder brother looking at?"

Gu Qinghuan cautiously asked, "What is this?"

"... "

Yinzhen raised his head and glanced at Gu Qinghuan, his eyes seemed to say: "Don't make trouble."

But suddenly, Yinzhen seemed to think of something again, and asked: "Can you see these graphics? This is a homework assigned by Huang Ama, and it is a proof question."

"I remember that you, Ama, are on duty at Honglu Temple. These geometry problems were brought from the West."

"ah."

Gu Qinghuan pretended to be surprised, and said: "No wonder the servant looks so familiar. When I was young, Ama taught the servant when she had nothing to do."

"..." Yinzhen's eyes flickered slightly, as if he didn't quite believe it.

However, Gu Qinghuan came up to him all of a sudden, pointed to the two straight lines on the picture and said, "Do you want to prove that this line is equal in length to this line?"

Yinzhen nodded and asked, "You know?"

"Of course!"

As soon as Gu Qinghuan picked up a writing brush on the table, he began to draw on the paper.

"Make an auxiliary line first, and then prove that the two triangles are equal. Then..."

Gu Qinghuan did it in one go, almost in the blink of an eye, he solved the problem that had troubled Yinzhen all afternoon.

PS: Kangxi is indeed a math fan. He can not only do geometry problems (including trigonometric functions), but also is proficient in geography.
