On July 5th, Zhou Ming rested at home for a day. On July 6th, Zhou Ming took the high-speed train to NJ again. Again at Tianhe Stadium, he participated in the mental arithmetic ability test of "The Strongest Brain".

Zhou Ming called Wang Yunqing, the chief director of "The Biggest Brain" yesterday, and asked him if he could challenge the mental arithmetic project. He is also good at mental arithmetic.

Wang Yunqing was overjoyed, because the "Most Powerful Brain" column team has been frantically looking for mental arithmetic masters across the country, but they can't find a mental arithmetic master who can surpass the competition.

Especially two years ago, Chen Lanlan, the "Queen of Mental Arithmetic" of Country Z, tied with Hiroaki Ishiya, the "Great Emperor of Mental Arithmetic" of Country Z, and announced her retirement. Since then, on the stage of "The Most Powerful Brain", the mental arithmetic masters of Country Z have They all disappeared. I don’t know whether it was because Ishiya Hiroaki was really too strong, or because he was afraid of being embarrassed if he lost. In short, no one who was powerful dared to go up.

Now that he heard that Zhou Ming was interested, Wang Yunqing planned to give him a chance to perform on stage again. However, this "Magic Cube Emperor" suddenly studied "mental arithmetic" across fields. He had a question mark in his mind as to whether his strength would be enough.

Test room.

"3216+5024+5324+5245+1255, this is the addition of five four-digit numbers, contestants please answer."

3.5 seconds later, Zhou Ming showed the answer board in his hand: 20064, and said to the female scientific assistant in front of him: "Addition is too simple, change to multiplication that is more difficult."

"Okay, here is a multiplication of nine times five digits, 165465456×46456, please start answering!"

Less than 5 seconds later, Zhou Ming showed the answer board in his hand: 7686863223936, and said: "It's not difficult enough, let's change it to a more difficult one!"

"The answer is correct. Next is a large-digit multiplication of seven digits by eleven digits. The difficulty level is very high. Please look at the question board on the big screen."

Keli pointed to an electronic screen on the wall of the testing room and asked Zhou Ming to look at the question board in the center of the screen:

6314859×87420397516

After the question board displayed this question, Zhou Ming took one second to imprint the two sets of numbers into his mind, then worked his brain for two seconds, started to write, immersed himself in the answer board, answered quickly, and wrote down a series of numbers:

552047484037490244

When Zhou Ming pressed the timer and compared the answers, the scientific assistant couldn't help shouting: "Absolutely correct, less than seven seconds, too fast, too fast!"

Director Wang Yunqing on the side also widened his eyes and looked at him like a monster for a while, then asked: "Zhou Ming, how long have you been practicing mental arithmetic? Your mental arithmetic ability is completely among the top in the country." Now that I have reached the level, I am fully qualified to enter "The Most Powerful Brain" and have a PK with Hiroaki Ishiya, the 'mental arithmetic king' of the Foot Basin Country!"

Zhou Ming chuckled: "I practiced this project together with the Rubik's Cube, probably for more than a month..."

"It took just one month to reach this level..."

Wang Yunqing opened his eyes to the extreme and looked at him in disbelief. From which planet did this monster in front of him fly to the earth? What is the purpose of your coming to the earth?

After complaining in his mind, Wang Yunqing gave him a timely reminder: "Zhou Ming, your level of large-digit multiplication is very good, but Ishiya Hiroaki is best at large-digit division. You are also very good at division mental arithmetic." The strength?"

On the surface, the mental arithmetic of multiplication and division should be equally difficult, except that one is a forward operation (multiplication) and the other is an inverse operation (division). However, because the human brain has different ways of thinking, some people are good at forward operations, while others are good at it. The majority of people are good at inverse and forward operations, but only a handful are good at inverse operations.

For example, people's handedness is definitely much more right-handed than left-handed.

Zhou Ming smiled and said: "No problem, I think division is simpler than multiplication. It will save many digits and make the answer faster... If you don't believe me, just ask the questions quickly and you will know after testing."

"The following is a division of eleven digits divided by six digits. Please be prepared to answer."

26243504882÷567329

46258

Buzzing, Zhou Ming quickly wrote out the answer and pressed the timer.

"The answer is correct, it took 3.8 seconds!"

"The next question is more difficult. It is a division of a sixteen-digit number by a nine-digit number. Please watch the questions on the question board for answers!"

2191669850969445÷589240137

3719485

After the question appeared, Zhou Ming wrote the correct answer in an extreme time.

"It took 5.7 seconds, absolutely correct!"

After answering two questions correctly in a row, director Wang Yunqing lost his composure and loudly shouted to the assistant: "Quick! Take the division question that Hiroaki Ishiya used to challenge the brain king last year, and ask Zhou Ming to do it too, and see how much he wants. It takes a long time to figure out the answer!”

"Director Wang, you mean, the division of the eighteen-digit number by the eleven-digit number, which was calculated by Hiroaki Ishiya in more than seven seconds?"

Kosuke opened his eyes wide and asked in surprise. Last year's Brain King Challenge was unforgettable. Although Hiroaki Ishiya failed to win the Brain King trophy in the end, the powerful strength he showed through this division problem still made people... Everyone was impressed.

"Yes, yes, bring this question over quickly, let Zhou Ming try it, and see if he can break Shiwu Hongming's record!"

Wang Yunqing saw hope. He saw the program "The Strongest Brain". In the mental arithmetic project, he had been suppressed by the "mental arithmetic emperor" of the Foot Basin Country for three consecutive years. Now there is hope that he can turn around.

Zhou Ming, the ordinary young man in front of him, shocked and surprised him far more than any other contestant who had ever appeared on "The Strongest Brain".

This young man is extremely confident and arrogant! But he is never afraid of challenges. During the challenge, he can always show his strength to the limit of human beings, proving that the big words he uttered are not lies! He is also able to take things up and let them go, and does not bother to argue with the weak. He boasts that his brain is the most powerful brain and he will defeat all opponents! Wang Yunqing didn't really believe it, he only thought he was young and energetic, but now, he really started to believe it.

"Eighteen digits divided by eleven digits, that's more than 7 seconds. Now that I think about it, I've also watched this program. It seems to be 7 seconds and 48..."

Zhou Ming was also deeply impressed by the Brain King Challenge in the final episode of the third season of "The Strongest Brain". In this episode, the winner of the Brain King trophy seemed to be a 15-year-old boy named Chen Zhiqiang, nicknamed "Supernova" boy".

The technician quickly found the question and entered it into the background system of the question board.

The sweet-sounding scientific assistant also gently reminded: "Zhou Ming, please look at the question board carefully. This question is very difficult. I hope you will use your best strength to solve this question as quickly as possible and write The correct answer." After saying that, the assistant secretly gave him a wink.

"OK!"

Zhou Ming made a gesture, concentrated his attention, and stared at the countdown on the question board, 3, 2, 1, the question was displayed!

425688500537940536÷74169305821

Swish, brush, brush!

Boom!

Press timer, 5.35 seconds.

Zhou Ming had no reservations. Almost immediately after scanning the questions, he wrote his answer on the answer board:

5739416

Wang Yunqing, who was standing aside, quickly grabbed his answer board and asked the staff to announce the correct answer: 5739416.

"Correct, absolutely correct!"

Seeing the time used by the timer Zhou Ming again, Wang Yunqing was stunned, and the beautiful girl Keli next to him was also stunned. The other staff in the testing room were also there, and then they all looked at the man with admiring eyes. Everyone's faces , all with great excitement.

"Pah, pah~"

"Pah, pah, pah, pah~"

I don’t know who applauded first, and then there was a burst of applause in the test room, which could not be subsided for a long time.

"Xiao Zhou, you are the great savior of our "The Most Powerful Brain". Those who question and insult "The Most Powerful Brain" every day can finally shut their mouths now! Let's go! Don't say anything, Xiao Zhou, I’ll treat you to a big dinner!”

The red-faced director Wang Yunqing held Zhou Ming's arm and said, then he glanced at the eight or nine staff members in the testing room, waved his hand, and said boldly and generously: "Let's go, let's go together. I am in a good mood today. Invite you to have a feast together!”

"Long live Director Wang!"

There was cheering in the testing room!

…

At noon, he spent more than 10,000 yuan on a meal at a seafood hotel in the city. In the middle of the meal, Wang Yunqing answered a phone call. After finishing the meal, Wang Yunqing, who was slightly drunk, pulled Zhou Ming aside and said:

"Xiao Zhou, the column team has just adjusted the recording schedule. On July 10th, the eighth issue of "The Strongest Brain" will arrange for you to appear again! You will face the two apprentices sent by Hiroaki Ishiya. Don't underestimate him. These two apprentices, after returning home, practice mental arithmetic more and face the battle in the best condition! Also, your body cannot have another accident like the last time. It is best to arrive in NJ in advance, and the program team will arrange meals for you. And accommodation...Also, you have to keep your phone open so that you can be contacted at any time!"

"No problem, Director Wang." Zhou Ming nodded.

Maybe he still felt unsafe, so Wang Yunqing whispered in his ear again:

"Xiao Zhou, if nothing goes wrong during the recording of the eighth episode of "The Most Powerful Brain" and you successfully defeat Hiroaki Ishiya's two apprentices, the column team has decided to give you a bonus of 300,000! In addition, you will be rewarded for every episode in the future. The appearance fee for the show has been increased to 50,000, which means that as long as you participate in the recording of the show, you can still get 50,000 even if you don't participate in the challenge... Xiao Zhou, let me tell you secretly, Brother Shui Wang Yiheng's appearance fee is also this amount. Our column team is very optimistic about you."

"Oh~ Is there such a thing?"

Zhou Ming's eyes lit up, and he immediately patted his chest and made a promise: "Director Wang, please don't worry, even if the sky falls, I will still come to participate in the show, and try to arrive in NJ one or two days in advance... In this way, you should be relieved Bar?"

Wang Yunqing raised his head and laughed loudly: "Don't worry, absolutely don't worry!"
