After the cannon fodder of the Hou Mansion read my voice, he went on a killing spree.

The Taifu glanced at the ball, but it didn't fall apart.

After another look, it still didn't fall apart.

He couldn't help but speak.

"Miss Qiao, how long have you been working on this ball?"

The Tutor suddenly spoke, immediately attracting everyone's attention, and everyone looked towards where Qiao Niannian was.

I saw a round ball being placed on the table.

Looking at the round ball, everyone immediately recognized the thing.

When the third prince saw the ball, his eyes flickered. His eyes swept from Xia Rongyu to Qiao Niannian, and a hint of deep meaning flashed in his eyes.

The fourth prince and fifth prince did not speak, but looked at Qiao Niannian curiously.

What is the relationship between Miss Qiao and the prince? The prince is even willing to share his toys with her.

While the Seventh Prince was curious, his mind had already been spinning a few times.

The Ninth Prince was the most unscrupulous. He looked at the ball on the table and had no idea what was so good about it.

The key is.

Qiao Niannian played with toys in Taifu's class. Shouldn't Taifu punish Qiao Niannian severely?

How could he still talk to her with a smile?
For a moment, he couldn't understand the Taifu's thoughts.

On the other hand, the eighth princess Xia Chaoyan spoke in confusion.

"Miss Qiao, doesn't this toy belong to the Crown Prince? I remember that when Brother Wu and Brother Prince borrowed this toy, Brother Prince directly refused."

Her words hinted to everyone that the relationship between Qiao Niannian and the prince was unusual.

He also instigated the relationship between the fifth prince and the prince.

The fifth prince was not a fool. He hurriedly explained: "I heard that this thing is particularly difficult to spell, so I wanted to borrow it for fun."

"The prince was also working on it at the time, so he didn't lend it to me. However, he later sent an identical one. Unfortunately, I haven't put it together yet."

"Miss Qiao is already very powerful if she can spell it out."

The fifth prince countered Xia Chaoyan's words, and also said that he and the prince had always been in harmony.

Xia Chaoyan's expression didn't change at all, and he said something calmly.

"So, Chaoyan has misunderstood."

The fifth prince did not continue to say anything.

Xia Muyan, on the other hand, was reading quietly when the Tutor came over. He didn't dare to glance around, so he didn't notice Qiao Niannian's progress at all.

Now that she heard Taifu speak, she couldn't help but glance at Qiao Niannian.

At this glance, I saw that the ball on the table had been put together.

She couldn't help but exclaim.

"Nian Nian, you are so awesome. In just two quarters of an hour, you have already done your best."

"I worked hard for several days!"

The results haven't been spelled out yet.

Xia Muyan didn't say the last few words, but this didn't stop her from praising Qiao Niannian.

As soon as these words came out, the Taifu beside him couldn't help but be surprised.

"You put it together in two quarters of an hour?"

Qiao Niannian nodded: "It's done."

At this time, the fifth prince was shocked.

Only those who have tried it personally know how difficult it is.

Not only the fifth prince, but also the third prince looked at Qiao Niannian with a change in his eyes.

The third prince had not gotten along with Xia Rongyu since he was a child. When Xia Rongyu was praised by his father for making a ball, it was said that Xia Rongyu could figure it out in half an hour. He was very unconvinced at that time.

Someone also made a similar toy and went back to put it together.

After working hard for several days, I finally succeeded.

But just because it took too long, he became more and more annoyed and looked at Xia Rongyu more and more unpleasantly.

He was four years older than Xia Rongyu. Xia Rongyu spent half an hour and was only eight years old when he succeeded.

He was already twelve years old at the time, and it took him three days to spell it out. He never said anything about this.

The people around him were also given death orders by him not to speak out.

But this incident was as uncomfortable as a thorn in my heart.

Xia Zeqi doesn't like people who are smarter than him. Xia Rongyu already made him unhappy before, but now there seems to be another Qiao Niannian.

He originally planned to let Qiao Niannian marry him and become his third prince's concubine, but now that he saw how smart Qiao Niannian was, the third prince was a little unhappy.

What is a girl so smart doing?
The smarter a woman is, the more self-righteous she is. Women should be simpler, so that men will like them.

If Qiao Niannian marries him, the first thing she must learn is to be a less smart woman.

The third prince was already thinking about how to change Qiao Niannian.

Qiao Niannian is still accepting Xia Muyan's flattery.

"Nian Nian, you are so awesome! When my brother, the prince, made this spherical shape, it took him a full four-quarters of an hour, and you were half as long as he was."

Qiao Niannian couldn't help but look up at Xia Rongyu.

Xia Rong and Fenghua Zhengmao had faint smiles on their faces, and their eyes looked over with a hint of admiration.

Qiao Niannian couldn't help but look away.

"This round ball is actually not that difficult, as long as you are good at math."

She felt that she might have been exposed to mathematics.

The principle of this spherical shape is very simple. Use the formula to calculate the area of ​​the ball, then find a center position and calculate a value.

According to the numerical value, find the corresponding wooden block. There is a gap of one millimeter between the front and back of the wooden block, and then directly subtract one by one, and so on, to calculate the area of ​​the remaining wooden block.

Next, you just need to be patient and puzzle it out.

So, very simple.

But ancient mathematics was not that simple. Relatively speaking, it was more complicated.

Xia Rongyu was able to spell it out within four quarters of an hour using his own brains, which was also very impressive.

When Taifu heard the word mathematics for the first time, he touched his beard.

He has been studying and reading books all his life, and yet there are still things he has not touched. It is really shameful.

Taifu is a studious person, and he is very willing to ask questions without shame when he encounters problems that he does not understand.

So, he asked Qiao Niannian for advice.

"What is mathematics?"

Qiao Niannian also didn't expect that one day she would have to explain to others what mathematics was.

"In fact, mathematics is a universal means for humans to strictly describe and deduce the abstract structure and end of things..."

Qiao Niannian took a piece of paper and a writing brush, directly listed the conversion formula of the sphere and solved it.

Then I talked about the way of thinking again.

easy to understand.

Not to mention the Taifu, even the Ninth Prince understood it.

"It turns out that this thing is that simple."

"According to what you say, this prince can do it too."

"And if we encounter similar things in the future, can we solve them this way?"

Qiao Niannian nodded: "The principle is the same. The specific situation still depends on the specific things. There is no difference."

Qiao Niannian's explanations are easy to understand and explain in simple terms. Such a profound issue can be completely explained by her casual explanation.

The Taifu's eyes were heating up when he looked at Qiao Niannian.

This is a scholar’s ​​academic pursuit.

Qiao Niannian's scalp was numb at the sight.

She silently put the white paper away and planned to form it into a ball.

But the Taifu snatched it away.

"Miss Qiao, can you lend me this thing to study?"

There is something profound here.
