When I was a guest at my girlfriend’s house, her dad took out the Desert Eagle

in the hall of the villa.

Others are silent.

I'm not sure if the answer written by Kong Xuan is correct.

And Xu Zihan was silent.

It was Kong Xuan who shocked him too much.

In fact, the topic she originally came up with was not so difficult.

It is simply to open a root number for 999.

The answer is accurate to two decimal places at most.

But when Kong Xuan asked her how accurate she was.

She didn't know what to think either.

Maybe it's because I was angry before.

The ghost messenger said, "Accurate to thirteen decimal places."

This is all at once, and the difficulty is directly full!

Give a 29-digit number square root.

Even if it's herself.

It's also thinking for twenty seconds.

before the results were reached.

And Kong Xuan, who has not undergone special training.

It's only a few seconds slower than her!

In her opinion.

It's absolutely incredible!

Then there is only one explanation.

This kind of annoying guy in front of me.

I also used to have special mental arithmetic training!

But why didn't the program team tell themselves?

Or rather.

Even the program team doesn't know about this?

This guy is hiding from everyone?

Thereupon.

She looked at Kong Xuan in her eyes.

A little more resentment.

Damn guys!

actually deliberately pretended to be a little white in front of himself.

Harm yourself and underestimate your enemies.

Not only did it not trick him.

Instead, it made him show off.

How unreasonable!

The sound of a calculator ringing in the hall.

Lin Xuerou's fingers trembled a little.

She couldn't believe it.

My boyfriend can really calculate such a complex problem.

This is far beyond what she knows about ordinary people.

And in the old days together.

In addition to being more self-disciplined, the boyfriend is more self-disciplined.

Never showed anything out of the ordinary.

Could it be said.

What a genius your boyfriend is?

The calculator presents the results of the calculations.

Everyone except Xu Zihan.

They all turned their heads over.

And then find out.

This result.

It is exactly the same as the answer written by Kong Xuan.

This time.

Even Xu Feng, a professor of mathematics at Qingbei University, is not calm.

Within thirty seconds.

Give a 29-digit square root.

And it's still mental arithmetic!

He has been known as a "mathematical genius" since he was a child.

Of course you know how difficult it is!

Even among the very few mathematical geniuses.

Only a very small number of people like Xu Zihan who are proficient in mental arithmetic can do it.

But how did Kong Xuan do it?

He was eager to ask.

But Kong Xuan still closed his eyes.

His brow furrowed slightly.

It seems that he is still trying to think about something.

Xu Feng was a little incomprehensible.

Obviously, the answer to this question has already been written.

What else is he thinking?

Wait!

Xu Feng suddenly had a bold conjecture.

This conjecture made his eyes widen.

Nope!

Absolutely impossible!

No one has been able to do that in such a short period of time!

"Hey!".

"What are you doing!".

"You're right. "

"Let's get the next question. "

"Ink!".

Xu Zihan looked at him with his eyes closed.

Firmly think.

He must be pretending.

Instantly mock yourself.

This made her even more angry.

But at the same time.

Again, she had to admit it.

He does have two brushes.

Also for the past few years.

The only one.

In the field of mental arithmetic.

An opponent who makes himself feel pressured.

So.

While being full of resentment towards him.

There was also more respect.

But who knows.

Kong Xuan's eyes didn't open.

Instead, reach for the hourglass.

Then flip the hourglass a bit.

Then continue to meditate with your eyes closed.

The others who watched this scene looked at each other.

A confused face.

Only Xu Feng frowned.

Staring at him.

Gradually realize the seriousness of the matter.

- "What's the situation? I don't understand. "

- "The protagonist probably means that the others will wait for him for thirty seconds. "

- "But what else is he thinking?"

- "You're not thinking about what's next, are you?"

- "Possibly. "

- "No, it's possible that he's trying to create a generic matrix!".

- "Huh, what's that? what's upstairs talking about?".

- "It's like a formula in a math problem, the kind that can be applied to the same type of problem!"

- "Oh, I see, that is, with this matrix, he can easily solve more complex root number problems. "

The previous world record holder for 200 digits to the 13th power in 77 seconds used the matrix technology he created. "

- "Do you know what you're talking about upstairs? It took the foreign god four years to create that kind of matrix, and you think the protagonist can do it in thirty seconds?

- "I also think it's nonsense, it's better to say that the protagonist is tired of thinking and is closing his eyes to recuperate!".

Finally.

After the hourglass ran out again.

Kong Xuan opened his eyes.

The brow furrowed.

There was a little joy in his eyes.

Xu Feng raised his eyebrows.

Surprise in my heart.

Could it be said.

He has completed the matrix conception?

Such a short period of time.

It may not add up to less than a minute.

Is it really possible?

This universal matrix.

Xu Feng also studied.

If only he started from scratch.

It may take at least a few months.

Of course.

It's not for mental arithmetic.

Similar to the mental arithmetic matrix studied by foreign world record holders.

Even if he is given a few more years.

Xu Feng didn't dare to guarantee that he would be able to study it.

And Kong Xuan's identity is just an ordinary person.

Even if he was a top student and a top student when he was in school.

That's unlikely to create such a difficult matrix!

Not to mention in such a short period of time.

Xu Feng didn't dare to jump to conclusions.

It can only be observed.

And at this time.

Kong Xuan has already started to solve the problem.
