The time came to seven o'clock in the evening.

A full hour has passed since the start of the test.

However, according to the difficulty of this set of test questions, most of the students who took the test only achieved the dozen questions.

Except, of course, some demonic characters.

Qingcheng City, Zhuyuan Community.

Cheng Nuo rubbed his somewhat sour eyes, moved his fingers and smiled, "There are only the last ten questions left!"

That's right, compared with other top students who are still hovering over more than a dozen questions, Cheng Nuo has come to the 41st question!

This is a question with a basic score of 2 points.

2+3=13

3+4=25

4+5=41

5+6=？

The requirement of the question is to introduce how much the final "5+6" is equal to according to the law of the above three equations.

After Cheng Nuo glanced at it, different numbers flew in his mind.

Suddenly, the corners of Cheng Nuo's mouth slowly hooked. "Was it the Pythagorean theorem?"

Soon, Cheng Nuo filled in the blank with the answer - 61!

The next one, the reasoning question, has a basic score of 3 points!

The topics are as follows:

There are five people: A, B, C, D, and E. Each wears a white or black hat on their head. Everyone can see the color of the hat on someone's head, but they can't see the color of the hat on their own.

If a person wears a white hat, he is telling the truth, and if he is wearing a black hat, he is telling a lie. Here's what they said:

A said, "I saw three white hats and one black hat."

B said, "I saw four black hats."

C said, "I saw a white hat and three black hats."

E said, "I saw four white hats."

Q: What color hat does each of them wear?

This is a very basic reasoning question.

"It's another question to send points. Cheng Nuo shook his head and chuckled. I filled in the answer as if I had it handy.

Cheng Nuo pressed the OK button to enter the next question.

"In five seconds, the question will appear, so get ready!

Such a prompt is displayed on the screen, next to which there is a five-second countdown number.

At the same time, many of the 100,000 candidates did the same thing as Cheng Nuo.

They couldn't help but give up their gaze and stare intently at the computer screen.

3！2！1！

A number appeared on the computer screen: 651!

After a second, the first number disappears and the next number appears: +157!

One more second later: -541!

Next second: -211!

............

Every second, the previous number on the screen disappears and the next number appears.

What the contestant needs to do is sum all the numbers that appear on the screen. The result of the sum is the final answer.

This question tests the player's fast computing power and memory. To be precise, it's "fast computing power" or "memory."

If you have enough quick computing power, you don't need memory at all, just calculate the result at the same time as the problem is finished.

But if you're not very good at quick computing, you can rely on a strong memory, write down all the numbers that appear, and then slowly calculate them in your mind.

Cheng Nuo is not talented, and he happens to have both abilities.

When it comes to memorizing numbers and computing power, I'm afraid only robots can do it themselves.

-294！

+947！

Ten numbers, which take ten seconds, appear on the screen one after the other.

When the last number, "+947", disappeared under their noses, the inner thoughts of the top students who were doing this question were like this: "???"

Who am I, where am I, what am I doing?

This question...... What the hell am I ...... How to do it!

One number per second, even if you remember it at the time, but when you look at the next number in the next second, you are nervous and forget the previous number, how to break it?

Needless to say, if you misremember a number, you only need to remember a number incorrectly, and the question will not be correct at all.

This question may be simple for those who have been trained as a child for mental arithmetic.

But...... For the top students who have never been exposed to this kind of topic, I am afraid that nearly half of them will be planted here.

"1024, that's right, it's you!"

On the other hand, Cheng Nuo did not hesitate after the ten numbers were displayed on the screen, and quickly filled in the blanks with the answers.

Don't compete with me for speed, let you have a calculator, I'm faster than you!

That's right, with Rejoice, it's so confident!!

............

There is also a gap between the top students.

For Cheng Nuo, a man who is a scholar, although he has just set foot in the field of scholarhood, he is already destined to be an extraordinary half of his existence.

From this set of test questions, you can see the difference in the level of different top students.

Yes, they can only dominate in their respective schools.

And some, the note will become the shadow of the entire Huaguo scum.

Cheng Nuo is the one who is working in this direction.

"The last question?"

Unconsciously, Cheng Nuo had come to the last question.

The last question is a test of the contestants' observational skills.

Base score, five points!

"It's over after completing this question!" Cheng Nuo smiled faintly and looked at the screen.

To Cheng Nuo's surprise, this question took up ten pages of screens.

The requirements for this question are as follows.

The system will then generate a three-by-three grid for the player.

The nine-square grid is filled with nine small colored squares.

The color system of the lattice is divided into white, green, orange, yellow, red, and blue. It is the same as the six colors of the Rubik's Cube.

And the ten pages of the screen, each page of the screen, is presented by 60 x 40 squares filled with these six colors.

It's the same as the original challenge project of "The Strongest Brain", the Rubik's Cube Wall. However, the arrangement of the six colors is more irregular than that of the Rubik's Cube wall.

Players look at the nine-square grid color blocks given by the system, and according to the order of colors, find the exact position corresponding to the nine-square grid color blocks in their hands in the ten Rubik's Cube walls, and find out them.

To be honest, the difficulty of this question is quite large.

Six color blocks, 60*40 ten Rubik's Cube walls.

The corresponding color order is 60*40*10*6, a total of 576,000 possible.

What the contestants need to do is to find the only order of arrangement given by the question from these 576,000 possibilities with their own eyes that can see through everything.

Ten Rubik's Cube walls, it takes a long time to read them all.

If you miss the position of the correct answer halfway through......

That...... It definitely feels quite sour!

At this time, in a certain community not far from Cheng Nuo, a teenager was suppressing his urge to cry, and his eyes were red and he kept flipping the ten Rubik's cube walls.

It can be clearly seen that the question number displayed in his question is...... 1！

That is, he has spent more than an hour on this question.

At this moment, the door to the room was pushed open, and a figure wearing a deer-hunting hat walked into the room.

He hugged his arms and looked at his younger brother in front of the computer desk, "Hey, Bai Feng, is this question so difficult? I see you've been pondering for more than an hour?"

Bai Feng suddenly turned his head and glared angrily, "Bai Yan, what you said is light, or you can do it." ”

Bai Yan shrugged, "What's not to do then." I'm a police detective, and I'm observant, but I'm my forte. ”

Half an hour later, Bai Yan's wail came from the community, "Who came up with such a perverted question!"
