Good! ”

After a short silence, I don't know who shouted, everyone came back to their senses and coaxed, which immediately pushed the atmosphere of the audience to a climax.

It's not a big deal to watch the excitement, and the mentality of onlookers at home and abroad in ancient and modern times is not the same.

Seeing that Zhou Xuan was not a joke, the old master shook his head, turned back to the back hall and asked whether the questioner disagreed, and the onlookers erupted in cheers.

At this time, even Zhou Xuan didn't notice it, and the onlookers' expressions when they looked at him had unconsciously changed dramatically, from the original contempt, to the later consternation, and then to the current admiration.

Everyone had a thought in their hearts, maybe this poor acid could create a miracle.

"Please ask Zhou Gong to make a question!"

After a while, the old master came back from the back hall and spoke loudly.

Everyone's eyes immediately turned to Zhou Xuan, and everyone couldn't help but look forward to what kind of problem he would come up with.

However, Zhou Xuan didn't expect the questioner to agree so simply, he just fought back instinctively under anger before, but it was difficult for him to make the question, after all, judging from the question of Fang Cai, the level of the questioner is definitely not low.

But if there is no real problem, the other party will inevitably continue to entangle, and maybe even some trap will be in the end, so that he can return the thousand taels of silver that he has already received with both hands, and even Zhao Cheng will not dare to offend the mysterious questioner, and this may not happen.

The conspiracy theories in my heart couldn't help but think wildly, Zhou Xuan really needed this money too much, and the more he thought about it, the more chilling he became, so he simply turned his heart sideways, planning to come up with a question that the other party would never answer.

I saw him pick up his pen, write a few words quickly on a blank piece of manuscript paper, and then hand the title to the old master.

The old master took the manuscript paper and was slightly stunned, and exclaimed: "Your topic is actually calculating pi?" ”

As soon as this remark came out, everyone was shocked, even people who don't understand arithmetic understand the difficulty of calculating pi, which is a problem that countless arithmetic masters have solved all their lives, how can anyone calculate it on the spot?

Seeing this situation, everyone couldn't help but admire Zhou Xuan, don't look at him as if he is inconspicuous, but as soon as he makes a move, it is a trick, and there is no way out at all.

The old master smiled bitterly, and reflexively returned to the back hall with the questions that were swirling around.

Everyone was suddenly happy in their hearts, the mysterious questioner played everyone all morning, but they didn't expect to be born at this time, and they could watch a good show with their own way.

"Hey, it seems that your classmate is very shrewd!"

A bachelor sneered and said to the bachelor surnamed Chen.

The bachelor surnamed Chen said angrily: "Scoundrel, villain, what is the difference between such a question and a scoundrel and a villain?" Zhou Xuan is really a villain! ”

This angry rebuke immediately attracted everyone's side eyes, and the fellow bachelor patted the bachelor surnamed Chen on the shoulder, and said in a low voice: "Brother Chen doesn't have to be like this, although the covenant of a thousand daughters has a great impact, and Zhou Xuan's overnight fame is unstoppable, but if you think about those celebrities who have been defeated, Zhou Xuan climbed up on their shoulders, and the mysterious questioner, she is so ugly, can you let Zhou Xuan go?" ”

When the bachelor surnamed Chen heard this, he suddenly turned his anger into joy, and said with a smile: "That's right, that's the truth, arithmetic is arithmetic, even if it's famous, it's the last learning, but those celebrities, hum, have his ...... to feel good."

Suddenly, the voice of the bachelor surnamed Chen stopped abruptly, and not only him, but everyone quieted down because the old master had returned.

No one thought that the old master would come back so quickly, even if he couldn't calculate pi, he should pretend to be, everyone thought that he would have to wait at least for the other party to find a step down, but he didn't expect him to come back so soon, could it be that the person who asked the question had already given up treatment.

Zhou Xuan's face was also satisfied, and after finishing the question, he could not help but start thinking about the last few steps of analyzing pi, but before he had a clue, he saw the old master's shocked expression, and his heart couldn't help jumping.

The old master held a piece of manuscript paper in both hands and trembled slightly, and the look of shock on his face lingered for a long time, as if he had just watched an incredible performance.

At this time, everyone also came back to their senses, and there was an unbelievable possibility from the old master's face, could it be......

"It's been calculated, it's been calculated......"

The old master looked up at everyone and muttered in his mouth, his tone trembling slightly and with a thick shock.

"What?"

When everyone heard this, they were in an uproar, and if it weren't for someone from the academy to stop them, they would have rushed up to see the manuscript paper in his hand.

And the most shocking thing is not them, but the circle that has been concentrating on calculating pi.

"No way, no way!"

Zhou Xuan's eyes widened suddenly, and he rushed to the old master in one step, grabbed the manuscript paper and took a closer look, only to see that it was written: "Pi is the ratio of the circumference to the diameter of the circle, which is an infinite circular decimal number, about 3.141592654, and there are countless bits after that, if you are interested, you can infinitely deduce!" ”

In addition to the complete solution, there are more than a dozen solutions such as Zhang Heng's solution in the Han Dynasty, Liu Hui's "cut circle" solution, the square root solution of Aya Bodo in ancient India, and the seventeen-digit exact numerical solution of the Arab mathematician Kassi.

Some solutions have been thought of before, but they haven't had time to study them, but more of them are unheard of, unseen, and even unthinkable.

"How so...... How is that possible? ”

Zhou Xuan trembled and picked up the pen and hurriedly calculated on the manuscript paper, but no matter how he calculated, the result was exactly the same as the answer on the manuscript paper.

Years of hard work, countless white eyes, just for this small answer, but now the answer appeared in front of his eyes, just half a pillar of incense.

Zhou Xuan laughed miserably, feeling that fate had played a big joke on him again, pi was regarded by himself as an unsolvable problem, but it was not worth mentioning to others.

He suddenly felt worthless, even a sad joke, and the persistence and belief in his heart were shattered in an instant.

Zhou Xuan raised his head and saw the pillar next to the wall, and suddenly had a strong will to die in anger and sorrow, and he was about to really hit himself headlong.

And at this moment, a soft female voice suddenly came from the back hall.

"Mr. is good at arithmetic, and my son-in-law has something to give!"

As soon as these words came out, everyone suddenly looked towards the door of the back hall, only to see a charming woman walking out of the back hall, the woman was gorgeously dressed, pink and delicate, and her face was radiant, which instantly attracted everyone's attention.

"Liki, isn't this Liji?"

The sharp-eyed man suddenly called out her identity.

Hearing this, everyone was even more shocked.

Today's Liji has long been famous in the capital, even among the royal ladies and noblewomen, if the ladies and ladies in the capital can't get in touch with her, or if she has a guide or two, they are embarrassed to go out.

She seems to have become the world's earliest socialite and fashion master.

As soon as everyone saw that it was her, they immediately thought of the name of the person behind her, and all these seemingly impossible results in front of them immediately had a reasonable explanation, and they were instantly relieved.

The study of the ghost valley turns decay into magic, which is especially evident in the yin and yang family Xu Rui, who is full of learning, and when they think of the legendary knowledge, they can't help but salivate, lamenting that they have no way to learn, which is a big regret in their lives.

But Zhou Xuan is no one else, he has been staying at home for many years, and he doesn't know who the bright woman in front of him is, and the mixed emotions make his head even more confused.

It wasn't until Liji walked in front of him and handed him a thick booklet that Zhou Xuan reacted, and hurriedly opened the booklet to take a look, just a few glances, and suddenly his face changed, and he sat on the ground.
