Chapter 2 Selection of Normal Distributions

Zhang Heng ran seven laps around the playground, 2,800 meters.

After that, he went to the public bathroom to take a shower, changed into a clean white t-shirt and jeans, and had breakfast in the cafeteria. Then he came with the book "Xiaoshan Wanhua Mirror" that he had just finished reading. library.

Reading like running in the morning is also one of Zhang Heng's habits, and he maintains a speed of one book a week.

However, unlike the morning run forced by his grandfather, reading can bring him a lot of fun. It is a kind of pastime, and he himself has been enjoying it all the time.

In fact, if it weren't for the limited time, he would have liked to read a few more books a week.

After going through the book return procedure at the service desk, Zhang Heng took out his mobile phone from his pocket.

Open a small program called a random number generator, set an eight-digit number, and then... roll it out with great interest.

It must be admitted that it is not without reason that this product is always thought by people to be gods.

Anyway, normal people borrowing books in the library will never show off this kind of sleazy operation of picking books by roll point.

But Zhang Heng's reading has an advantage, or a quirk. It may be because he has read a lot of books since childhood. This guy is not afraid of being cold, and he is full of poison. From world famous novels to Long Aotian Xiaobai Wen, and even the president of Jinjiang. He can read it with relish, and his condition is still deteriorating. Today, he can even read "Compendium of Materia Medica" and "Scientific Pig Raising Handbook", and there is basically no cure.

In order to avoid the trouble of picking books and enjoy the simple joy of encountering good books, he created this set of normal distribution calligraphy.

It is a pity that when applying for the campus scientific research award, I unfortunately fell out of the list, and there is no funds for follow-up promotion.

Therefore, the capital market always lacks vision.

…………

Zhang Heng came to the corresponding bookshelf according to the last two digits of the roll.

The luck this time is not bad. Although it is not a literature category, the management is also very interesting. At least it is better than the "Bill of Quantities for Water Supply and Drainage, Heating, and Gas Engineering" that he rolled last month. many.

Reaching out a finger, pulled this target out of the shelf.

--Adam Smith's The Wealth of Nations

Looks like we're going to have a nice morning.

Zhang Heng found a seat by the window and sat down, then started his leisurely reading time.

Maybe some people can't help but complain when they see this, is this okay? Does he care about his fine watch?

Zhang Heng said that he really can't handle this.

It’s right to actively respond after the incident, but it has to be something that you can deal with within your ability. For supernatural phenomena like this, when there are too few clues, perhaps doing nothing is the most correct choice, don’t you see In those classic horror movies, the mentors who turned around for you after being photographed on the back in the dark old house have all received lunches without exception.

On the contrary, you have to treat it as if it doesn't exist and go all the way to the end, maybe it's just a trip to the haunted house.

So, in many cases, calm is the most important thing.

Zhang Heng is very calm now. From the outside, you can't tell that he is in the middle of a supernatural event. This guy used the time to skip classes to make up for his morning run. The public elective course is critical thinking. In the evening, the promise is fulfilled, and the buddies who sleep with each other go to the food alley of the National University across the street to have a skewer. After returning to the dormitory, I even have the mood to watch a few episodes of American TV series.

Then at half past eleven, the dormitory was powered off on time.

Although Zhang Heng's laptop had its own battery, it could last three or four hours, but he did not affect the rest of his brother who was sleeping with him, so he decisively turned off the power.

In half an hour, the day will end. Other people's watches have already made two laps, and the familiar and unfamiliar starfish in his hand has just completed a full circle of the hour hand.

Will something happen? Zhang Heng didn't know, now all he can do is wait.

Zhang Heng put on the headphones, turned on the mp3, lay on the bed, and spent the rest of the day quietly for half an hour.

00:00

The three hands coincide on time at the top of the dial, about a blink of an eye, after which the second hand continues to swim.

During this period, Zhang Heng did not notice any abnormality.

Was the guess wrong? He took off his earphones.

But then something felt wrong.

Around - too quiet.

Summer nights are always extraordinarily lively, the small electric fan on the door squeaks and shakes its head, the annoying hum of mosquitoes in my ears, the unfastened faucet in the bathroom next door, the tick of water dripping on the sink, the tickling of wild cats wearing The salsa of passing the flowerbed downstairs, and of course the purring of the bed diagonally...

It all disappeared tonight.

The whole world seemed to have suddenly lost all sound and became silent as never before.

If it weren't for the faint singing in the earphones on his chest, Zhang Heng would even wonder if he had lost his hearing.

With the dim light of the mp3 screen, he looked at the time on his watch again.

It's 00:01

Usually at this time, the dormitory of the opposite door is still playing online lol, and you can hear the cheers after they complete the wonderful kill or the ultimate escape.

In addition, Zhang Heng also discovered another unusual thing. There is a date display on the right side of the starfish's dial. It is reasonable to say that the date above should also change after zero o'clock, but this time it is still the same. Stopped yesterday.

Zhang Heng's heart moved, and he seemed to think of something.

He didn't take off his clothes when he went to bed tonight, just jumped off it.

Starting the computer, the process of booting up was very smooth. It only took less than seven seconds. By the way, the QQ login interface popped up. Zhang Heng's attention was not on it. His eyes moved down to the toolbar. The date and time above Some dazzling.

00:00

2017/9/20

Is it really the last moment of "yesterday"?

Zhang Heng waited for a while, instead of looking at the time on the starfish, he pinched his pulse and counted 200 times. According to his 72 beats per minute, at least two minutes passed, but the desktop The time is still stopped at 00:00.

Zhang Heng raised his eyebrows, but did not rush to draw any conclusions.

He walked to the opposite bed and pushed Chen Huadong, who was still asleep. The latter was the lightest sleeper in the entire dormitory. Usually, anyone who got out of bed at night and took a sip would wake him up, but this time, no matter how Zhang Heng pushed him Nothing happens.

"Sorry brother, although I don't have a girlfriend, I'm not the kind of person you think."

While Zhang Heng put his fingers under the other's nostrils, he was able to take time out in this weird atmosphere.

It can only be said that the psychological quality of this product is really good.

After five minutes, Zhang Heng could not feel the slightest breath.

If this is also part of the prank, then Chen Huadong's breath-holding skills are too strong, and he can participate in the Guinness Book of World Records.

Since it has been done once, it is not bad for the second or third time.

Zhang Heng then followed suit and tried it under the noses of the remaining two roommates.

The result is the same as Chen Huadong.

Zhang Heng can basically conclude that he has indeed encountered a supernatural phenomenon that cannot be explained by science.

He is now in a time that shouldn't exist.

For example, it was as if the river of time had a branch for him.
