"Zhi! Zhi! ”

At half past seven in the evening, Cheng Jinyang returned home in a excited mood, and immediately wanted to share today's events with Miss Ah Zhi:

"You know what? There was an attack on the other side of Qinhuai District! ”

"Give you a chance to change your name in 3 seconds." Xing Yuanzhi was sitting on the sofa cutting her nails, and when she heard this, she immediately squinted at it, and the nail clippers in her hand exuded a sharp light.

"Ahem, Yuan Zhi." Cheng Jinyang coughed and said, "You know what? ”

"I know." Xing Yuanzhi tilted her head towards the TV screen, "The news just now was also urgently reported, and the price of 300,000 yuan was offered at six doors to reward the murderer. ”

"Really?" Cheng Jinyang was a little sneering.

It's like seeing the astringent picture excitedly posted to the group, and then everyone complained that they had seen it hundreds of times.

"There's a question I want to do for you." He took out the Cheng family's version of "Calculation Methods" from his bag and turned to the first question of the second chapter "Time Function", "Can you calculate this?" No calculator required. ”

Xing Yuanzhi glanced at it: "1.393 seconds." ”

Cheng Jinyang: ???

"Or else?" Seeing the puzzled look on his face, Xing Yuanzhi wondered and asked, "What's the answer?" ”

"The answer is right." Cheng Jinyang smiled bitterly, "How did you figure it out?" ”

"Equilateral right triangles." Xing Yuanzhi's expression seemed to say, "This can be counted with hands", "Didn't you calculate it?" ”

"I figured it out." Cheng Jinyang said, "But it took a few minutes to use a calculator ......."

"That'll do fine." Xing Yuanzhi said calmly, "People who have not received brain domain development are like this. ”

"What is brain domain development like?" Seeing that Ah Zhi was really led to this topic, Cheng Jinyang immediately asked.

"Brain domain development ......" Xing Yuanzhi thought for a while, and then explained to him:

"The traditional human mind is instinctual and untrained, understand?"

"For example, your brain is like a big library, and your memories are like books piled up in it, scattered randomly on the floor, distributed irregularly."

"When you need to calculate, you see the problem, and after you have a general impression, you know that you need to use the four knowledge points A, B, C, and D to correlate them to get the solution."

So you look for four books in the great library of your mind, representing A, B, C, and D...... You put a lot of effort into pulling the books out of the stacks, checking them again and again to prevent yourself from making mistakes, and finally you come up with a solution. So, why did it take so long? ”

"Because it took time to find it." Cheng Jinyang said.

"That's right." Xing Yuanzhi said, "The human brain is not a computer, and there is no way to quickly extract information from memory, so it can only obtain data from intermittent memory elements one by one." ”

"If you practice a certain type of question too much, like you have memorized the positions of books A, B, C, and D in the brain library, then the efficiency of doing the questions will increase. Of course, this doesn't change the inefficiency of 'books are still scattered'. And, if you change the question type and change the set of knowledge points, the efficiency you have accumulated because practice makes perfect will still be zero. ”

"The so-called brain domain development is to change your brain library from a scattered and disorderly distribution to an orderly, categorical arrangement. There are many things that need to be explained in detail, such as the series and parallel placement of knowledge units, the path optimization of addition, deletion, modification and query, and the modeling thinking framework that can be scanned at high frequency......"

"Stop!" Seeing that Miss Ah Zhi had a tendency to start discussing academics, Cheng Jinyang hurriedly shouted to stop, "How do you develop your brain?" Can only the Shendu Cheng clan carry out the development? ”

"What I just said is the method of brain domain development!" Xing Yuanzhi was a little annoyed by his direct and rude interruption, "Of course, in words you can understand, it is to take a bunch of electrodes and stick them on the door of your brain, and then use drugs, GIFs, sounds, smells, electric currents and other external sensing factors to stimulate you to help your brain reconstruct your thinking patterns." ”

"Of course. Each family has different ability bloodlines and different algorithms, so the most appropriate mindset is also different. The algorithms of Cheng Xing's two families are relatively close, so it's not impossible for you to go to Xing's for brain domain development, but the thinking mode established in this way is ...... It's definitely not as good as the Cheng family, understand? For you, the best brain domain development is still in Chengjia. ”

"After all, I have their blood in my veins." Cheng Jinyang said.

"That's right." Xing Yuanzhi nodded, "This is the meaning of the family. ”

"Well, I see." Cheng Jinyang sighed.

It's time to take some time and get in touch with Sister Xinnan...... Hey, I don't seem to have her contact information?

Yes! Last time, before leaving, I forgot to keep one!

He took out his mobile phone and rummaged through it, but he didn't find Cheng Xinnan's information, but instead saw a text message sent to him by the store manager who worked before, asking him if he had recovered.

So Cheng Jinyang replied by typing, euphemistically saying that his health was almost better, but he was not very short of money recently, and there were more things, so he wanted to quit his part-time job.

The store manager's reply was also very fast: It's okay, I recruited a new person on the day you took leave last Friday. However, you kid shouldn't be raised by a rich woman, right?

"Poof." Cheng Jinyang was drinking water, but he almost didn't squirt, but choked himself.

He coughed violently and stood up and walked in the direction of the living room balcony.

Xing Yuanzhi, who was sitting on the sofa, suddenly turned her head to look at his back, her eyes widened, revealing an expression of disbelief.

With some hesitation, she picked up the napkin box from the coffee table, put it down again after a few seconds, and then got up and walked briskly into the bathroom, taking out the cleaned mop.

The few drops of water on the floor that he had just coughed violently had sprayed were carefully mopped clean with a mop.

On the balcony, Cheng Jinyang sent a text message to the store manager:

Why?

The store manager replied: I am not in good health and frequently ask for leave, I don't have enough time, and I suddenly don't lack money, what is it that I am not supported by a rich woman? Young people should pay attention to moderation, after all, money belongs to others, and your body is your own.

Why am I suddenly speechless...... Cheng Jinyang looked up at the night sky outside and fell into an infinite melancholy mood.

It was already dark, but the main city across the river was still brightly lit, and even a faint halo over the city obscured the light of the moon and stars.

…… If the children of the family are the stars and the moon, when will I become the city that never sleeps to suppress their glory?

Such a thought flashed, and Cheng Jinyang suddenly remembered a story, which was about Qin Shi Huang parading the world, and two folk teenagers were watching the emperor's car in the crowd.

Xiang Yu said: He can take his place! (I can replace it!) ）

Liu Bang said: Huh, the husband should be like this. (Alas, that's how a husband should be)

In the end, Chu and Han competed, and everyone knew that Liu Bang defeated Xiang Yu and won the world. So this story tells us that we must not easily set up a flag......

Cheng Jinyang shuddered suddenly, and then hurriedly continued to look at the starry sky and prayed:

It's impossible to be a city that never sleeps, and it's nice to be a star like them and have the opportunity to shine your own light.

Hurry up and take a bite of your own milk, from Xiang Yu line to Liu Bang line, hurry up!

Here, Xing Yuanzhi washed the mop in the bathroom, came out to re-check the floor, and found that there were no "saliva stains" left, so she breathed a sigh of relief with satisfaction.

Although Xiao Yun, the housekeeping robot, will come to clean it at 8 o'clock in the evening, she still can't stand the stain remaining on the floor for so long.

Suddenly, there was another knock on the door.

"Who?" Xing Yuanzhi shouted, thinking that the housekeeping robot came over early today? WHAT'S WRONG WITH THE PROGRAM?

"It's me, Sister Yuan Zhi." Wang Wanrou's smiling voice sounded outside, "I've come to apologize to my senior." ”
