How to break into a math book

Already having this kind of ability to win, Tu Hua is not in a hurry to pass the level now.He had to find Wang Boyu first, and then meet with Tang Bo and Bai Jiaqi to discuss what had happened in the past two hours.

No one was seen at the agreed meeting place, so Tu Hua went directly to the nearest library.The library is as crowded as the teaching building. Almost every reading room has quests. Although most of them are side quests, the other challengers don't know the details, so everyone is eager to try.

Tu Hua soon saw Wang Boyu who was crowded in the crowd. He was tall and his prickly hair was very conspicuous in the crowd.

When Wang Boyu turned around and saw Tu Hua, his jaw almost dropped: "Tu Hua?! Where did you go?! I've been looking for you in the swimming pool for a long time! I almost thought you drowned in the swimming pool!"

Tu Hua was speechless, and pulled him away from the crowd: "I was just involved in a side game, what about Tang Bo and Bai Jiaqi?"

Wang Boyu pointed to the door of the reading room: "They just entered this level."

Tu Hua glanced at the large white characters floating at the door of the reading room, which was also a side mission.He originally wanted to ask Tang Bo and Bai Jiaqi to go through the main mission together, but now he doesn't know when the two of them will be able to get out of this dungeon, it would be a waste of time to wait.

The scarlet letters on the top floor of the library read [Main Mission: Mr. X’s Labyrinth] very abruptly. Tu Hua thought for a while and asked Wang Boyu, "I found a main mission. Do you want to go with me?"

Wang Boyu followed Tu Hua's gaze and said strangely, "The top floor? There's nothing there."

"I said yes." Tu Hua raised his lips and dragged him into the elevator, "Let's go."

After all, Wang Boyu and Wang Boyu can be regarded as good friends from birth to death. Tu Hua told him the tears of the mermaid and what happened at the witch level. Although your math performance is not very good, but I think there must be meat to follow you!"

The phrase "not so good in math" was really heart-wrenching, but seeing Wang Boyu's admiration, Tu Hua reluctantly forgave him. After all, brothers are like siblings, and it is duty-bound to bring brothers to the top.

There is a large reading room on the top floor, which is full of classics on mathematics, and a line of red letters is marked on the door [Main task: Mr. X's maze].

As expected by Tu Hua, the main quest did not trigger as long as one entered a specific place like the side quest. There were hardly any people in this reading room, and the two of them walked around inside without finding anything unusual.

Wang Boyu doubted: "Is there really a mission here?"

The layout of this reading room is very characteristic. The cross-shaped aisle divides the entire room into four parts, and each part has at least thirty bookshelves of different sizes.The administrator's desk is just in the center of the cross aisle, and it is not set at the door like other reading rooms.

There were no administrators, just a few sporadic challengers wandering among the bookshelves.Tu Hua walked to the nearest bookshelf, and when he was thinking about how to trigger this main quest, he saw a book called "X Maze".

Others may not notice this book, but they have already seen the obliteration of the task name in advance and locked it at a glance.The key to triggering the main mission must be here.

Just after he pulled out the book, the door of the reading room suddenly closed with a bang.Tu Hua turned his head and saw a tall man leaning on the administrator's desk which was empty just now.

As if he noticed Tu Hua's gaze, the man turned around and said with a smile, "Tu Hua, we meet again."

NPC teacher!It's the NPC at the first 24-point level!

He changed his look this time, which didn't match his identity as a librarian at all. He wore a silver-gray tuxedo, a dark red bow tie around his neck, and his hair was combed meticulously with hairspray. He looked like a British nobleman in the [-]th century. .

Although this shape is strange, Tu Hua has to admit that it is very handsome.

The NPC chuckled and snapped his fingers. The bookshelves in the entire reading room began to move crazily, as if they were trying to piece together some graphics. It took 5 minutes before the movement stopped.It is still divided into four parts by the cross-shaped aisle, but the bookshelves in each part are arranged in a mess. It doesn't look like a reading room, but a maze composed of bookshelves.

A few challengers came out of the bookshelf one after another, and Tu Hua counted them. Including him and Wang Boyu, there were five people in total.Before the level was triggered, there were at least seven or eight people in this reading room, and several of them were not brought into the mission.

That is to say, there should be a sequence relationship between the main missions. Challengers who have not completed the main missions of the previous step cannot enter the second step. The current five people should have already obtained [y=x^2-3x+ 2] conditions, the need for the final competition.

Tu Hua looked at the other three challengers, two girls and one boy. The two girls seemed to know each other. They stood together and whispered, their eyes kept glancing at the NPC.The boy looked very calm, leaning against the bookshelf next to him and not speaking.

These few people should be outstanding players who have experienced many mission levels, so they know the game routines well and wait for the NPC to announce the rules.

"Welcome six to Mr. X's maze. Mr. X is waiting for you at the end of the maze. If you find him, you can pass the level!" The NPC raised his hands upwards, and the bookshelves began to extend infinitely, and the entire reading room turned into a room. A huge maze with no end in sight.

"Six? Who else?" Tu Hua asked suspiciously.

"And me." Sun Wei came out from behind the bookshelf, and looked at Tu Hua thoughtfully.

Tu Hua really did not expect Sun Wei to appear here.After leaving the swimming pool, Tu Huashi once thought that Sun Wei might not be able to clear the level, because she only had two hours left, and the possibility of quickly finding the main task among the many tasks and successfully clearing the level was too low.

But now he has to look at him with admiration, Xueba's keen insight is indeed beyond the reach of ordinary people.

【Ding--】

The buzzer sounded, and the system officially promulgated the mission rules:

[Main task: Mr. X's maze]

[Rules: The challenger enters the maze, and every time he passes through a fork, he needs to answer the questions, and the correct answer opens the correct passage, and 1 point is awarded for 1 correct answer, and the challenger who meets Mr. X or finds the exit and has higher points than the previous challenger wins , with a time limit of one hour. 】

Four entrances appeared in front of the bookshelves in four parts, and the NPC smiled and looked around everyone: "Are you ready to enter Mr. X's maze?"

The rules this time are relatively clear. You need to answer questions when you enter the fork in the maze, and you just need to find the exit and meet Mr. X.The rules seem simple, but there are several difficulties: First, the rules do not mention the consequences of answering wrongly. Is it necessary to answer again and open the wrong path?If the answer is wrong, can the opened path reach the end?This is unknown.

Secondly, the level must be cleared within one hour, and the points must be higher than the previous challenger.This means that No.1 challenger is not restricted by points, while No.2 is higher than No.1, No.3 is higher than No.2, and so on.The uncertainty here is that the number of questions answered by everyone is not necessarily the same. If the total number of questions for No.2 is less than No.1, then he will never be able to pass the level.

Finding two points from the rules, Tu Hua pulled Wang Boyu into the maze entrance on the front right, while the two girls went to the entrance on the back right, the boys went to the back left, and Sun Wei quickly entered the maze behind them.

The countdown has already begun, and Wang Boyu is obviously a little nervous. Except for the first time he cleared the main level of Miss Y's Ice Dance, he has never seen any other missions, and he has never completed any missions alone. .

But the main task in front of him is obviously to be done by the challenger alone, and according to the rules, there is still a competitive relationship among the challengers.

Soon, the two encountered a fork in the maze.Tu Hua chose the intersection on the left, and said to Wang Boyu: "I guess all you encounter in this level are math problems. Aren't you good at math? So don't be nervous. Compared with other tricky and weird levels, this The main quest is easy."

Wang Boyu nodded and said goodbye to Tu Hua.It seems that Tu Hua is confident to cheer up his good friends, but in fact he knows very well that if this level requires a lot of math questions to answer, his winning rate is the lowest.

Among these six people, it is estimated that none of them failed mathematics like him.

Tu Hua sighed, and after turning two bends, he encountered the first fork in the road that needed to be done.There were exits on the two bookshelves in front of him, but the exits were blocked, and he had to answer questions to open the exits.

The system screen popped up, and as expected, what was displayed on the screen was a multiple-choice math question. Although there were only two options, in Tu Hua's view, this question was still difficult.

He frowned and thought for a long time before choosing the second answer.After he pressed the confirm button, the system quickly made a judgment and gave him a red cross.

Tu Hua was stunned for a moment. He really didn't expect that he was so unlucky. He stumbled on the first question, and the system didn't give him a chance to correct it. After the judgment was made, the question disappeared, replaced by a few large characters: [points :0]

Immediately afterwards, the exit restriction on the left side was lifted, and the passage can be passed through.

But he clearly knew that he had answered the question wrong just now, and the opened exit was not the correct passage, so Tu Hua had no choice but to bite the bullet and walk through.Because the correct passage next to it is always closed.

Tu Hua, who failed in the first battle, forced himself to calm down. Although this level is not friendly to him who failed in mathematics, it is still possible to pass the level.

If you can't lead to the exit if you answer the question wrong, there is no need for this maze to exist.There is no need for challengers to answer so many questions, as long as they answer one question incorrectly, they will be eliminated directly.And if he answered the question incorrectly, he could still go on, which proved that whether the question was right or wrong was not the final judgment on the challenger, at most he just took a few more detours than those who answered correctly.

After figuring this out, Tu Hua relaxed. After several missions and levels, he had a general understanding of Su Gechi's way of designing this game.He will never let students lose the opportunity to reach the end because of a mistake in a question or a failure in an exam. In his world, there is always another way to choose.

Just like he created this "Mathematics Breakthrough", he didn't want students to only have the opportunity of the college entrance examination, so he found another way, opened the shackles, and gave those with unique talents another way.
