After counting in one go, only 1 of the 30 double-digit digits was wrong.

The order is still exactly right.

Who can do it?

Passers-by, you look at me, I look at you, and bow their heads in shame.

"Yes, Yicheng, you're not a human brain, no, I mean you're a weirdo."

Yi Cheng looked at her with squirting eyes.

Is this a good thing or a bad thing?

"Wait, I'll test you again." Mo Xiaotian said as he typed text on his phone, "I'll type 30 words, and then see how many you can remember in 30 seconds." It's also the rules of the game just now, just report it from the beginning to the end. ”

As soon as he heard the word [word], Yi Cheng felt very big.

After a while, Mo Xiaotian finished typing and showed his mobile phone to everyone.

A few onlookers approached the phone screen with Yi Cheng.

【White Horse, Crow, Forest, Lily ......】

"Okay, 30 seconds over."

……

This time Yi Cheng could only utter less than 7 words, and the order was not entirely correct.

This level is much lower than the average person.

A normal high school student can shorthand more than 10 words in at least 30 seconds.

After some testing, Mo Xiaotian came to a magical conclusion -

Yi Cheng has a high sensitivity to numbers, but words are difficult to remember.

It's the opposite of ordinary people.

Such people do not do not exist, but there are very few.

Just like the legend that Xiang Yu is a heavy pupil, there is no third one in the long history.

God says that you are flawed because He likes you and takes a bite of you.

And then you become Apple.

……

"That's probably why you can't learn Chinese, English, and biology." Mo Xiaotian clasped his hands and frowned.

"You are not sensitive to words, so it is difficult to memorize words accurately, but your comprehension skills are quite strong, so you can do reading questions well."

It is not easy to have such a brain structure and maintain a score of more than 640.

Only those who know Yi Cheng know how much effort and sweat he has put into it.

"So what should I do?" Yi Cheng asked.

Mo Xiaotian was not the first to discover the problem.

This question has been asked by Chinese and English teachers before, but they don't have any effective methods other than the tactics of the sea of questions.

"Isn't there a saying in math that says it well?" Mo Xiaotian blinked his eyes and smiled slyly, "Negative is positive." ”

Yi Cheng looked at her with a confused expression.

After Mo Xiaotian's explanation, Yi Cheng was finally completely opened up.

The memory method she gave Yi Cheng was the only one in the world, and it was possible to refine this set of Jiuyang Divine Skills because of the blessing of the Xuanming Divine Palm.

How?

This method is called "refining the Nine Yin True Sutra." ”

Normal people use graphics to memorize words, and concrete memories are abstract.

For example, let's remember the thirty words she just said:

[White Horse, Crow, Forest, Lily, Gazebo, Notebook, Meat Sandwich, Peace Elite, Butterfly, Fluorescent Lamp, Square Dance, Circle of Friends, Trainee, Table Tennis, Airplane, Skiing, Progress, Princess, Monk, Mathematician, Brush, Nostrils, Atmospheric Pressure, Pacific Ocean, Circuit Board, Haircut, Bridge, Yak, Release, Towel]

Using meaningful associative mnemonics looks like this:

[The white horse chased the crow into the forest, met a pair of lilies, finished resting in the gazebo, and recorded the pleasure just now in a notebook, and then rested enough to play the peace elite, a butterfly flew in the peace elite, under the fluorescent lamp, the butterfly went to the square with a gun, and danced the square dance. After eating chicken, I forwarded it to the circle of friends.

Netizens said that you are not as good as the table tennis skills of the trainees for two and a half years.

When the table tennis plane went skiing, the princess got involved with the monk, and later the monk ran away with the mathematician, and the two of them practiced calligraphy together with a brush and used it to pick their nostrils.

The monk accidentally sneezed, which caused the atmospheric pressure to increase, and a tsunami flooded the Pacific Ocean and flooded the circuit board, causing the haircut to leak electricity, and the guests could not play bridge, so they could only ride a yak to make an announcement, and the content of the announcement was that the price of the towel had increased because of the flooding of the sea. 】

You see, after a while, I memorized all 30 words.

In the same way, memorize the words of the numbers:

316748691437

Translated as: If you go up to the first floor, you will die on the eighth floor

Through association, it is remembered immediately.

And the method that Mo Xiaotian taught Yi Cheng was just the opposite.

You see, this is called sharp-eyed and prescribes the right medicine.

"The other way around?"

Everyone asked in unison.

"Yes, use numbers to memorize words, and abstract to memorize concrete." Mo Xiaotian said.

I'm afraid this man is not a fool.

Passers-by looked at them strangely.

"Then Miss Huiyin, what should I do?" A passerby asked.

Mo Xiaotian blinked his eyes and thought for ten seconds.

"Hmmm......"

“emm……”

“emmmm……”

“emmmmmmmmm………”

It's constipation.

"You ask me, who do I ask?" Mo Xiaotian, who was born in liberal arts, was at a loss.

Only Yi Cheng didn't say a word, and fell into deep thought.

……

He closed his eyes and went over what Mo Xiaotian had just said in his mind.

Eyes and nose and nose and heart, and ...... Mathematics.

"Mom, this is going crazy, right?"

"Don't bother him!" Mo Xiaotian stopped everyone, "He has reached a critical juncture, the upper layer is soaring during the day, and the next layer is falling into the abyss. ”

"it!"

Yi Cheng suddenly opened his eyes and startled everyone with a loud shout.

"yes, why didn't I think of that?"

This is a one-way function that uses discrete mathematics and cryptography.

Tick-tock, wonderful rhythm of time.

Tick tock, Yi Cheng couldn't help but dance.

The first step is to transcode the text.

Remember the transcoding function as f(x)

x1=23，x2=M2

x3=……

Then, the second transcoding encryption is carried out through the hexadecimal and planar coordinate systems.

Yes, you read that right.

26 base.

After the transcoding is completed, Yicheng will get a graph.

It's really a beautiful curve, it winds and turns, like a catkins in spring, and like a babbling stream.

So wonderful, so moving.

And Yi Cheng can get a different one-way function every time he memorizes words, what a happy thing it should be.

After memorizing the graph, you can turn it around and get the initial answer.

"It's over, it's over, this man is going crazy." Passers-by sighed.

Only Mo Xiaotian was able to dispel public opinion, with a serious and amazed face.

"You've succeeded Yicheng, and you've found your own unique memory method."
