Keyboards are similar all over the world, even the dedicated ones in the library are not much different from the keyboards of this laptop in terms of layout. π stared at the keyboard for a moment and quickly pressed the first key.

Zhang Zi'an peeked through the crack in the door, and although he couldn't tell which key π pressed from his position, the general location should be the number area of the keyboard, that is, the row above the 26 English letters - after all, this laptop does not have a special keypad area.

Therefore, Zhang Zi'an can't see it, but he can guess what π is fighting - it must be pi again.

π why do you want to play pi? Is it for relaxation? Just like humans can relax when they play games?

If he's not mistaken, the default search engine on the browser's homepage limits the length of the data in the search bar and can't be typed indefinitely.

Sure enough, π quickly opened his mouth in astonishment, stared at the screen, and repeatedly pressed a number on the keyboard with his fingers in vain, but could not type the number up.

"Squeak!"

After several failures, it held its head in its hands as if it was very anxious, and its fingers pulled the short fluff on the top of its head, like a high school student who was troubled by esoteric math problems.

Zhang Zi'an thought about it, stood on tiptoe and went downstairs gently, and then went upstairs at a normal or even heavy pace, so that π could hear his footsteps and not be frightened.

He pushed open the door of the living room, walked in as if he didn't know anything, and said to himself, "I'm really tired after finishing my work......

π had already left the computer and sat on the sofa next to him, pretending to be reading a book, but unfortunately he forgot to close the browser before leaving.

Zhang Zi'an sat back in front of the computer, pretending to be surprised and staring at the screen, "Hey, I remember that I closed the browser before leaving......"

Unsurprisingly, the search bars of search engines are filled with that long list of pi numbers.

"Squeak!"

π was like a child who had done something wrong, lowering his head and covering his face with his hands, waiting for Zhang Zi'an's scolding.

"Is it the browser that π open? π is so smart! The other elves don't have this ability, only π can use a computer. Zhang Zi'an praised unexpectedly.

"Squeak?"

π lowered his hand and stared at him blankly.

"I mean, look at that African grey parrot who claims to be fluent in all languages, and it can't even use a mouse, let alone accurately type the top 100 positions of pi. "He spoke ill of Richard behind his back.

In fact, he didn't know if the top 100 pi π was correct, but it didn't matter, as long as it boosted his confidence.

"Squeak!"

π smiled, holding the book in one hand and patting his chest with the other.

Zhang Zi'an carefully pondered its meaning, and asked tentatively: "π mean, you can not only play in the top 100?"

"Squeak!"

π nodded vigorously.

"Uh...... How many positions can π play?" he asked curiously, "200?"

π shook his head and stretched his arms flat.

What does this mean...... Bigger than 200?

"That's 500?"

"Squeak!"

π still shook his head proudly, his arms stretched outwards as if he were doing a stretch of broadcast gymnastics.

"Uh......" Zhang Zi'an tried to guess again, "1000?"

"Squeak!"

π's movements were even more exaggerated, apparently asking him to guess at a larger number.

Because of disbelief, Zhang Zi'an was a little sweaty. He didn't know what the longest digit of pi a human could recite, and he couldn't imagine how this infinite non-cyclic number could be memorized, so he guessed, "10,000 digits?"

"Squeak!

π's expression was a little anxious, and his movements were even more hurried, as if he had guessed too little.

"Okay......" Zhang Zi'an felt that it would not be added ten times or ten times, it would be too much of a waste of time, since π was so confident, then he would say a big number.

"10 million?"

He vomited out the number nervously, for fear that he would overguess and hurt π self-esteem. This is a figure that humans cannot memorize under any circumstances, because it has exceeded the physiological limits of human beings.

Suppose you recite ten numbers in one second and recite them for 8 hours a day, it will take a month to memorize these 10 million digits.

"Squeak!"

π still shook his head, and Xiao Jump raised his arms to let him continue to guess.

Zhang Zi'an: "......"

Even if he believed in π very much, he couldn't help but wonder if he liked to brag as much as he did.

It happened that the laptop was on, he looked it up on the search engine, and as of now, the value of pi has been calculated to 60 trillion decimal places, even if π dick blows up, it is impossible to memorize these 60 trillion places, right?

"Squeak!"

Seeing his suspicious face, π patted his chest anxiously and waved the nameless book in his hand again.

"You mean, you can't do it on your own, but with this book, you can do it?"

Zhang Zi'an already understood π's expressions and movements to some extent, and he could guess the difference, after all, π was a young monkey, as innocent and easy to understand as a human child.

π nodded.

"Okay, then I'll guess a little bigger. Zhang Zi'an chose to believe it, after all, π is the only elf with a golden finger that has appeared so far, and the golden finger is, of course, the scarlet nameless book.

π nodded expectantly.

"1000 trillion bits?"

This was the last time he guessed, and even if he still didn't guess correctly, he wasn't ready to guess any more, because he didn't know what the bigger unit of counting was, and he would only be timid if he guessed again.

For a moment, π's expression did not change, and just when Zhang Zi'an thought he had guessed correctly, it grinned and continued to shake its head.

Zhang Zi'an raised his hands, "I surrender, I really can't guess." π Just tell me. ”

"Squeak!"

π scratched his ears and cheeks, as if he couldn't express his inner thoughts. Finally, it clenched its free hand into a fist and released it slightly, as if it were grasping something and slowly letting go.

What does that mean?

Zhang Zi'an looked confused, he was not an expert in sign language after all, and π was not a standard sign language.

"Squeak!"

π jumped off the couch and ran to the pantry with the nameless book in one hand and the floor in the other. After a few moments, it staggered on two feet like a human and returned with a bag of cat litter.

Zhang Zi'an didn't know what it was going to do, so he watched quietly.

π tore the bag of cat litter open, dumped some on the table, and then grabbed a handful of cat litter, let it slip from the palm of his hand, and motioned for Zhang Zi'an to see.

Zhang Zi'an became more and more puzzled, he was asking π how many digits can write pi, what is it doing with cat litter?

Seeing that Zhang Zi'an didn't understand, π grabbed a handful of cat litter again and continued to let them slowly slide from between his palms.

Mr. Zhang seems to have seen similar actions in movies and animations — like someone grabbing a handful of yellow sand, letting it slip through his fingers, and being blown away by the wind.

Wait a minute!

Zhang Zi'an suddenly had an idea, and a lightning bolt exploded in his mind, illuminating the darkness! He remembered that there seemed to be indeed one of the counting units related to "sand"! But that unit was so big that it was desperate......

"Is it as small as the sand of the Ganges?"

When he said this, even he couldn't help but tremble, and even got goosebumps all over his body.

The Ganges sand number is a double metaphor derived from the Buddhist scriptures, assuming that each grain of sand on both sides of the Ganges represents a Ganges, and the product of the Ganges sand and the Ganges sand is the Ganges sand number. It's hard to say exactly how big that number is, but it's enough to think of it as immeasurable.

"Squeak!"

π finally nodded, and it danced excitedly with the nameless book, as if it was glad that Zhang Zi'an guessed correctly, which also means that it can write pi to infinity length, and even to the end of time, which is longer than the lifetime of the universe - how long is pi, an infinite non-cyclic decimal, π can write as long as it is!

Zhang Zi'an didn't know what it was like in his heart, on the one hand, he was deeply shocked, on the other hand, this number was too exaggerated to dispel the doubts in his heart - did π really know how big the number of sand in the Ganges River was?

The biggest doubts are...... What's the use of that?

Generally speaking, in the common calculations at the high school and college levels, as long as the pi is recorded as 3.14, even if it involves some industrial calculations, as long as the top 10 of pi can be taken, and the more accurate calculations in the scientific field are only used to hundreds of pi digits, and then infinitely accurate, what is the use?

Humans can recite pi to tens of thousands, they can apply for Guinness World Records, they can become famous, they can become Internet celebrities, they can make girls at parties, and maybe they can make money by publishing a book that teaches you how to improve your memory, but what is the point of this for elves?

Whether it is a human or an elf, doing things needs meaning and purpose, and it is also cost-effective. Obviously, memorizing pi to infinity is the least cost-effective way to pretend to be, because no one knows if you're memorizing it correctly.

π didn't think so, it was deeply proud, squeaked with a nameless book in its hand, and happily circled around the living room.

Zhang Zi'an's eyes fell on the book, and the answer must be in the book—even π himself admitted that without that book, it would not have been able to recite pi to infinity.

It's a book about life, the universe, and everything, and if that's true, it's certainly pi as well.

It's useless to guess, and when π trust him enough, he will definitely ask π to show him the contents of the book, and it is better to write when he can find a girlfriend......

He looked at the time, and it was time to make tea for Lao Cha.

"π, wait for me in a while, I'll go and go back. He said, then walked straight into the kitchen, grabbed a jug of cold water from the faucet, and put it on the gas stove.

He just wanted to dry this bowl of Ganges water now to cool down.
