Zhang Zi'an made tea and brought it downstairs for the old tea.

The pet shop that has just entered the New Year is a little deserted, but this is normal, students in this period are preparing for their final exams, office workers are fighting for year-end bonuses, and retirees who have nothing to do are reluctant to go out in such cold weather.

It's good to get through this time, and when the Lunar New Year comes, the children have a lot of New Year's money in their hands, hehe...... Since Zhang Zi'an went to Little Celery's school, he deeply felt that the child's money was the best to earn.

Lu Yiyun has already started to paint, she has been a little mysterious recently, she is very sensitive to her own paintings, whenever Zhang Zi'an passes by the cash register, she will quickly switch the interface, which makes Zhang Zi'an can't help but wonder - could it be that she has betrayed her temperament for money, and is drawing animation welfare maps for those dead houses?

Lao Cha and Richard were watching TV, Fina and Snow Lion were eating and drinking, lying on the cat climbing frame and falling asleep, even Pegasus was sleeping, and the only vigilant person in the pet store was Zhan Tian, squatting outside like a doorman, shoulder to shoulder with the statue of the cat god.

Ever since he knew that Zhan Tian was a veteran police dog, his existence made Lu Yiyun feel at ease.

Zhan Tian saw Zhang Zi'an passing by, and stood up expectantly to stare at him.

"Wait a little longer and then go out. He said to it, and it sat down again.

Zhang Zi'an poured the tea into the pressed thermos pot of old tea - although this kind of thermos pot is not the most insulated, it is the most convenient to use for old tea.

"Meow~"

He was about to go upstairs to the kitchen with an empty teapot when he heard Xinghai shouting behind him.

As soon as he turned his head, Xinghai looked at him with silver-gray eyes and said, "Meow~ Zi'an, are π okay?"

Zhang Zi'an smiled: "π is very good, it just told me a very incredible thing." ”

"Meow~π is amazing!" Xinghai said solemnly and seriously.

"By the way," Zhang Zi'an lowered his voice and asked, "Does Xinghai know the book π?"

Xinghai nodded, "Meow~ Xinghai has seen it." ”

"That book...... Is it really a book about life, the universe, and everything?" he asked Xinghai, even if π was bragging, Xinghai couldn't help it brag.

Xinghai replied without hesitation: "Meow~ Yes, yes! That's a very powerful book! It's the most powerful book on earth!"

it!

Zhang Zi'an was taken aback, the most powerful book on the planet?

Although he already knew that this book was all-encompassing, he could actually be handpicked by Xinghai as the most powerful book on earth?

Xinghai tilted his head and thought about it, and added: "Meow~ It may not be the most powerful on other planets." ”

Well, the affairs of other planets have nothing to do with me.

For such unimaginable things, Zhang Zi'an left them behind very freely and returned upstairs with the kettle.

π was in the mood for the excitement to pass, and he sat down in front of his computer again, typing pi over and over again in the browser's search bar.

When it saw Zhang Zi'an coming, it was only a little embarrassed, and it didn't dodge like just now.

"π, this search engine has a maximum length limit, if you want to score pi, I'll install a word processing software for you. Zhang Zi'an proposed.

π didn't seem to understand, and the brown eyes behind the pinched glasses blinked, and opened the book with a clatter. After a few moments, it happily closed the book and moved out of the way of the computer.

"Squeak!"

Well, Zhang Zi'an guessed that it was asking him to install software.

This old computer was reinstalled in the system, and then it was put on the shelf by Zhang Zi'an, and there was nothing in it - this happened after the elves arrived, mainly to destroy the bodies of the big sisters in the hard drive, so as not to cause trouble.

Zhang Zi'an looked through the genuine office set he bought before, although the version is quite old, but it's still no problem to hit pi or something.

Insert the disc into the optical drive, and after a lengthy disc reading process, the Office word processing suite is installed correctly.

Start the ORD and a new new document appears on the screen.

Zhang Zi'an pressed the number key, typed 3.1415926 in the document, and then moved to another sofa by himself, asked π to sit back in front of the computer, and continued to type.

"Squeak!"

π excitedly put the book on the coffee table, stretched out his hands, and pressed the different number keys on the keyboard in turn.

The nameless book was between it and Zhang Zi'an, and he could reach it as long as he reached out, but he resisted his curiosity with twelve points of perseverance, and tried not to read the book, but to concentrate on reading the π and pi - although it was really boring, and the endless numbers were dizzying.

However, since π can do this, it means that he is somewhat relieved, right?

After a while, he noticed that π's typing posture was not quite right, similar to the old Mr. Zhou he met in the library - Mr. Zhou used one-finger Zen, π slightly better, used two-finger Zen, and only used the index finger of his left and right hands to type, which was very inefficient.

I see, π typing is slow, so when in the library, it only types a string of pi at regular intervals.

"π, you're typing in the wrong way. He reminded aloud.

"Squeak?"

π paused typing and stared at him in bewilderment.

"Shall I show you the correct posture?" he asked.

"Squeak!"

π moved to the side.

Zhang Zi'an sat down in front of the computer again, straightened his posture, and put his ten fingers on the keyboard.

"π, you see my two index fingers are right on the F and J keys, and each of them has a little bump that allows your index finger to touch them exactly when you're at rest. ”

He patiently demonstrated the correct typing posture and fingering, explained the area controlled by each finger, and how to move the finger correctly.

"Squeak?"

After the demonstration, π imitated Zhang Zi'an's posture and tried it himself, but it didn't go well, its knuckles were not as flexible as humans, and its ten fingers were always entangled, and it became agitated after a while.

"Squeak!"

π scratched his head, gave up studying, and started typing with two-finger meditation again.

Zhang Zi'an decisively pressed its hand, "π, don't give up just because it's hard - if you don't develop a correct typing posture, after a long time, your fingers will be prone to various joint diseases." ”

He didn't know how big an ORD document could be, but it was okay to hit millions of numbers, and if π kept typing in the wrong position, it was only a matter of time before he would suffer from knuckle disease.

"Squeak?"

π looked at him suspiciously.

"You can look up your book, it should be written in it. Zhang Zi'an pointed to the nameless book and smiled.

π Yiyan opened the book and turned the pages with a bang.

After a moment, it put down the book and bowed its head guiltily.

"Squeak. ”

It's like an apology.
