How to break into a math book

Tang Bo's classification method was irrefutable. Even if Tu Hua felt that something was wrong, he couldn't find a more convincing point.Everyone decided to try Tang Bo’s method. Seven people including Chen Li, Zhang Wenwen, Tu Hua, Wang Boyu, Li Tao, Shen Siyi and Tang Bo climbed up to the red high platform on the left, and the three people of Cap, Sun Wei and Zhao Yiwei climbed onto the platform. On the right blue value range platform.

Everyone held their breath, waiting for the system's trial.

【Ding--】

[Challenge failed. 】

The hope that was finally ignited was shattered again, and there was only one last chance left.If they still can't pass the level, ten of them will be eliminated together.Despair and exhaustion hung on everyone's face, Tang Bo blamed himself very much, and the excitement and confidence just now were swept away.

Everyone sat quietly on the ground, and no one spoke for more than ten minutes.Tu Hua patted Tang Bo on the shoulder: "There is one more chance, don't be depressed. Since the challenge failed, it proves that your plan just now is not impeccable. Let's think about it together and see if the method just now still exists What a loophole."

Tang Bo supported his forehead: "I really tried my best."

Shen Siyi on the side suddenly said: "Could it be that your classification doesn't have a directional correspondence?"

Directivity?Tu Hua suddenly realized that the corresponding rules of functions are actually directional. After some transformation, x can get the corresponding y. This relationship is directional. From x to y, there is an accurate sequence between them. .But the method given by Tang Bo has no clear direction.

Taking the region as the corresponding relationship, this kind of regional correspondence can only show that there is a certain connection between the definition domain and the value range, but there is no process of x pointing to y.The directionality of gender correspondence is even more confusing. These are basically just a classification method, and there is no directional correspondence between them.

Shen Siyi's opinion hits the nail on the head: "Whether it's geography or gender, there are very broad commonalities, which are not enough to form a unique corresponding relationship between us. I think this relationship should be more detailed."

"Isn't it a commonality? Is it a characteristic?" Zhang Wenwen said, "Could it be to find common ground between our hobbies and specialties?"

"He just said about directivity, didn't you hear?" Li Tao stood up and said disdainfully, "Whether it's hobbies or specialties, it's just to find commonality among characteristics. The real contradiction of the problem lies in direction. It is a relationship of a certain order that two people have between them."

Although Li Tao's tone was not kind, he grasped the point of the question. Zhang Wenwen glared at him: "You like to refute others so much, so you have a reliable suggestion!"

Li Tao's face froze and he didn't speak.

Although there is no clear result yet, they must be thinking in the right direction. Tu Hua felt that his head was a mess, and all kinds of information were intertwined. He had to find the correct line: "We are now Although we have a clue, our thinking is still messy. We must sort it out. First of all, the directional relationship between us is common. Simply put, it is assumed that there is such a directional relationship between Wang Boyu and Sun Wei. , then the rest of us must also have the same directional relationship as them.”

"Secondly, the specific manifestation of this relationship is not a universal commonality, but our characteristics. But what special things happened to each of us, only we know, others don't know, and the system doesn't know."

After listening to Tu Hua's analysis, Shen Siyi's eyes lit up: "The system doesn't know?"

Tu Hua raised his lips. Although the ten of them are not familiar with each other, if you really want to find commonalities in their characteristics, you will definitely get countless answers.In a game without criteria, where every answer could be correct, the odds of them trying to answer what the system deems correct are simply too low.In fact, this game is not difficult, but they imagined the game system of "Mathematics Breakthrough" to be too powerful.It's just a game, it's not God, and it won't be so comprehensive to everyone.The information that the system can get is very limited, and it is impossible to know what these people's specialties and hobbies are.

Unless the challenger says it himself.

"The system didn't know who would enter the [Function and Number Set] level at the beginning, so I concluded that before we entered the level, the system didn't know what the corresponding relationship between us was." Tu Hua paused , "But now it knows, and set an answer it thinks is correct."

Shen Siyi glanced at Tu Hua approvingly: "So the key to the problem is how the system got this answer, that is to say...how did he know the hobbies and characteristics of each of us."

Sun Wei's eyes widened: "It... heard it?"

Tu Hua nodded: "Although there is no NPC in this level, the system has been observing us since each of us entered the game. He listened to us and monitored our words and deeds, just to draw such a conclusion before the game officially started. There is a corresponding correct answer."

Everyone is thinking about what they said and did when they entered the checkpoint.But with the exception of Chen Li, Zhang Wenwen, Cap and Wang Boyu, the four chatterboxes, the others said very little, and there seemed to be no effective information.Tang Bo also said: "Since I entered this checkpoint, I have never said anything about revealing my own information."

Except for Tang Bo, Shen Siyi, Li Tao, and Tu Hua basically didn't speak.

"Thoughts." Sun Wei raised his head suddenly, looking at the misty sky, "The system knows what we are thinking."

Everyone was stunned.Sun Wei analyzed calmly: "From a technical point of view, we enter the game "Mathematics Breakthrough" through iris scanning, and then the system controls the brain center. It is entirely possible to read the thoughts in our brains."

"It's terrible!" Chen Li's face turned pale, "It knows what we're thinking, so don't we have no desire?"

The peaked cap said: "As far as I know, this system of playing games through iris projection is a patent just developed by Su Gechi and his company some time ago, and it was only the first batch of trial production in "Mathematics Breakthrough". It is true that many people questioned the security, but later the technicians explained that although the player's state of mind can be obtained during the game, this technology has no archive function. That is to say, the game is over , the information obtained by the system will also disappear.”

Tang Bo frowned: "So can the system really read our thoughts?"

This is the first time that everyone has discussed such a serious ethical issue.Tu Hua didn't know what kind of person Su Gechi was, but he had a vague feeling that Su Gechi was not the kind of person who would do bad things.He has wonderful ideas and loves games. How could he destroy his favorite world with his own hands?

"The topic is off topic." Tu Hua stood up, "Whether this game will steal our secrets or not, we can only make a conclusion when we return to the real world, but at least Su Gechi gave us a direct access to University A in this game." Opportunities. All we can do now is to clear these missions and seize the opportunities.”

He continued to analyze: "If the system can read our thoughts, then please remember well, what everyone said and thought from the time you entered this level to the time when the system officially announced the start of the mission."

Wang Boyu took the lead and said, "I was talking about that fantasy novel with Chen Li and Zhang Wenwen. I haven't read it or bought it, but I just heard that it's very popular, so I started talking about it."

"As for the idea..." Wang Boyu glanced at Zhao Yiwei secretly, "Zhao Yiwei looks a bit like the girl in the class next to me, and... that girl gave me a love letter last week."

Zhao Yiwei's face turned red in an instant. She was standing next to Wang Boyu, but she went around and found a place farthest from him to stand there, as if hiding from the plague.

Wang Boyu scratched his head: "It's not that I'm narcissistic, she really sent me a love letter..."

Tu Hua was helpless: "Okay, okay, I trust you. What about the others? Can you tell me about your own situation?"

Chen Li and Zhang Wenwen looked at each other and said, "The two of us have been discussing about queuing up to buy that fantasy novel, and we haven't thought about anything special."

The peaked cap said: "Me too. The only special thing is that after my mother donated my novels and comics, I felt very sad."

When it was Zhao Yiwei's turn, she was a little shy: "I didn't think about anything special, I just remembered discussing "Assassination of 711" with classmate Sun Wei."

Tu Hua was taken aback for a moment.He was next to Zhao Yiwei and Sun Wei when they were discussing. At that time, Zhao Yiwei said that she had bought the game CD of "Assassination 711", and Tu Hua thought that he happened to give this CD to his tablemate.

These fragmented information seem to have some kind of connection.He and Zhao Yiwei, the peaked cap, Chen Li, and Zhang Wenwen, all have a relationship through a certain item, but what about directivity?Is there any directional connection among these events?

"I only talked to Zhao Yiwei a few words about mystery novels." Sun Wei said suddenly, "As for thoughts...my thoughts seem to overlap with those of Wang Boyu."

Tu Hua looked up at her.

Sun Wei turned his face away, and his eyes fell in the air: "I remembered the thing about confessing to the boy in the next class in the second year of high school and sending him a love letter."

Tu Hua knew that Sun Wei was talking about himself, but he didn't feel any embarrassment or embarrassment at all. His energy had been completely devoted to this game.

Wang Boyu received the love letter, and Sun Wei handed over the love letter; Zhao Yiwei bought the CD of "Assassination 711" and gave it to the tablemate; Chen Li and Zhang Wenwen bought the fantasy novel, and the peaked cap donated the novel...

Tu Hua suddenly realized, excitedly said: "It's 'get' and 'give'!"

"Getting and giving are the directional correspondence between us! First of all, the relationship between the three of you," Tu Hua walked between Chen Li, Zhang Wenwen and the peaked cap, "The connection between the three of you is the fantasy novel , you two lined up to buy the book, it was 'getting', his book was donated, it was 'giving'."

"Then there is Wang Boyu and Sun Wei. The commonality between the two of you is the 'love letter'. When Wang Boyu received the love letter, it was a 'get', and when Sun Wei sent the love letter, it was a 'give'." Tu Hua turned to Zhao Yiwei and said, " Then there are the two of us, you bought the CD of "Assassination 711", it is a 'get', and I once gave this CD to my deskmate, it is a 'give'."

The author has something to say: Worship the Great God Yelingxue who made a summary in the previous chapter! !Great!applaud!

ps: Professor Su’s game question is an important foreshadowing ~~ I hope you won’t forget it in the future _(:з」∠)_
