How to break into a math book

Before Li Tao had time to export his attacks and insults, his body turned into pixel particles and disappeared.Tu Hua just used a trick to lure him into being fooled, let him attack Shen Siyi, took advantage of this opportunity to save Shen Siyi, and Shen Siyi could just use a crossbow to get rid of him.

Kill two birds with one stone.Tu Hua completed the last task of saving people, and Shen Siyi also happened to complete the last task of elimination. The two of them cleared the level perfectly within the time limit of one hour.

At the beginning, 25 challengers entered the game, but in the end, only five of them actually passed the level, and the other 20 were all killed by their compatriots.

The means of the virus are getting more and more cruel.

The two became the final passers who completed the task, and the system awarded rewards to them:

【Ding--】

[Challengers Tuhua and Shensiyi cleared the side mission battle selection level, Tuhua got the number 6, and Shensiyi got the number 7. 】

Tu Hua didn't expect that both he and Shen Siyi would be able to get the number to complete the main task. In this way, everyone in their four-person team had already obtained the stepping stone to the main task within 48 hours.

Tu Hua's number is 6, Shen Siyi's is 7, Sun Wei's is 9, and Wang Boyu's is 5.

They completed the task ahead of schedule, and there were still 48 hours left in the 13-hour time limit given by the system when they left the checkpoint.

[Battle selection] Su Gechi failed to follow up in this level. When Tu Hua left the level, he found that Su Gechi had been waiting for him outside the level, and his face was a little dignified.

He hurried over: "what's the matter with you?"

Su Gechi looked at him: "The last level... the virus program blocked me."

Tu Hua knows what Su Gechi's words mean. In the last level, Su Gechi did not follow him into the level. If it is because the virus program opened the shield, then it is very likely that he will continue to encounter in the next level. to this situation.In this way, Mr. X's reasonable hack will be useless, and Tu Hua will not be able to get help from Su Gechi. He can only break through the level with his own strength like other challengers.

This is indeed a crisis for them.

But Tu Hua felt that this was just a good time for him to break away from Su Gechi's wings and prove himself independently.Even in the face of a powerful virus, he is confident that he can pass the level.

He took the initiative to hold Su Gechi's hand, and showed a confident smile under the surprised gaze of the other party: "You have to trust me."

He is no longer that fledgling kid, he can withstand the pressure and go hand in hand with his partners.

Su Gechi's frown was finally loosened, showing a gentle smile, touching the top of Tu Hua's head and whispering: "Okay."

When Tu Hua and the others went to meet Wang Boyu and Sun Wei for a reconciliation, they found Wang Boyu standing in front of Sun Wei with his head bowed, as aggrieved as a quail.And Sun Wei folded his arms and said something to him bitterly.

Tu Hua came over and patted his shoulder: "What's wrong?"

When Wang Boyu saw Tu Hua, he immediately stood behind him like a wronged daughter-in-law, and said pitifully, "You are finally back."

Sun Wei snorted, "You are so big, can you stop acting like I bullied you?"

Shen Siyi: "Did you bully him?"

Sun Wei rolled his eyes: "Ever since you left, he has been chattering beside him, saying that he is all to blame, that he has caused everyone to suffer. I persuaded him a few words, and he continued endlessly. It's..."

Wang Boyu sighed, and said to Tu Hua and Shen Siyi: "But it's really all my fault, I'm really sorry..."

Before the words fell, Sun Wei shouted: "Shut up!"

Wang Boyu immediately kept silent.

"You stand here for me!" Sun Wei pointed to the open space beside him, "If you say sorry again, we will kick you out of the team!"

Wang Boyu looked tearful, like a clumsy bear, obediently moved to Sun Wei's side.

Sun Wei looked at him and said: "We don't have anyone to blame you, you are innocent. If you always have this feeling of self-blame, how can we break through the next level? We are a group, teammates fighting side by side, We are all on the same page in any situation, so what if we made a mistake? Together we can make it up and right it!"

Wang Boyu stared at Sun Wei bewilderedly, with reverence and admiration on his face.

Shen Siyi coughed, and Tu Hua looked at him with a smile, and then said to Sun Wei treacherously: "It's better that you can control this guy, why don't you let him deal with it in the future?"

Sun Wei blushed and turned around: "Who wants to talk to him."

Wang Boyu hurriedly went up to her sleeve and pulled her sleeves. If there was one, her tail would have been wagging: "Take care of me, talk to me!"

Everyone laughed.

The ten hours of waiting outside the checkpoint quickly passed. Tu Hua turned on the system to check the status of the main task of [Sequential Level], but found that there are currently less than 200 challengers left, which means that in the previous side task , knocking out nearly half of them, not counting the challengers who didn't get numbers.And the next main task is not known how cruel it will be, and the subsequent levels may become more and more difficult to pass.

At the end of the 48-hour period, excluding challengers who have not yet obtained numbers, there are a total of 150 challengers who can enter the main line level.

The system finally promulgated the main mission rules.

【Ding--】

[Rules for the main task of the series level: There are 150 remaining challengers in the level, 10 people form a group, and each forms a series according to the corresponding numbers of the system.But only 10 of the 7 people are numbers that really belong to the sequence. Please select 7 people and arrange them in order, for a total of three chances.If one failure occurs, 10 team members will vote together to select one person to be eliminated. If the eliminated person is 7 people who do not belong to the sequence, the game will continue; if the eliminated person is a member of the 7 people forming the sequence, then all members will be eliminated. 】

After the rules were promulgated, the system regrouped the 150 challengers. Fortunately, all four of Tu Hua were grouped into one group, while the other six in their group were three women, two men, and an old man. Opponent Sui Li.

Ten people got together and reported their numbers to each other.

Tu Hua's number is 6, Wang Boyu's number is 5, Shen Siyi's is 7, Sun Wei's is 9, Sui Li's is 17, the other three girls are 3, 12, 15, and the two boys' numbers are 11 and 13 .

也就是说涂化这一组的十个数字按照大小顺序排列分别是：3、5、6、7、9、11、12、13、15、17。

According to the rules, 10 of these 7 numbers can form a sequence, and the other 3 numbers are interference items. Ten of them must discuss a correct result, and select 7 people to sort according to the sequence of the sequence. There are three sorts in total. chance, and if the order is wrong, they must vote to eliminate one person.

If the person who is eliminated is one of the 3 interference items that do not belong to the sequence, then others can continue the game, but if the person who is eliminated is one of the 7 people in the sequence, the game will end directly. 10 people will be eliminated at the same time.

The number sequence they were looking for was not a random sequence, but a sequence that met the requirements of the system.For this reason, the system gave a prompt message: [If there is no 3].

The other 14 groups are also playing games in full swing, but Tu Hua's group is at a loss for the information of this sequence.

[If there is no 3] What kind of reminder is this?Based on this ambiguous prompt, it is impossible to accurately judge what the sequence specified by the system is.

Shen Siyi took the lead in analyzing the rules: "According to the current rules of the elimination competition, we have a total of three chances to answer. If the first two answers are wrong and the last answer is correct, in the process of team member elimination, we will have three chances to answer. Up to two people can be eliminated, that is to say, people with 3 distracting items, on the premise that we can pass the level, at least one person can be kept."

The girl with the number 3 said: "But in fact, our chances of clearing the level are not very high. If we make a mistake in the first sorting, it means that we must correctly eliminate the people who interfere with it before we can get the next chance to sort."

"And the odds are only 3/10."

Sun Weidao: "Without our knowledge of this sequence, the probability is indeed very low. But the system gave us a prompt condition, and now we must judge the probability of this sequence as much as possible according to the law of these 10 numbers and the prompt condition." features."

13号男生点头赞同孙维的说法：“我观察了一下我们这10个数字，发现这些数字中大部分是奇数，恰巧包含3、5、7、9、11、13、15、17这个奇数列。”

Wang Boyu was a little puzzled and said, "But your odd number sequence has 8 numbers in total. Doesn't the rule say that this sequence has only 7 numbers?"

Boy No. 13 analyzed: "Isn't the prompt given by the system [if there is no 3], if the 3 is removed from the odd-numbered column, there will be only 7 numbers left?"

这个男生的意思明显就是说3号女生是干扰项，3号女生当然不满，反驳道：“你这样的定义也太随意了吧？我是不是也可以说【如果没有3】代表的是包含3的数字，或者被3整除的数字？那这样3、6、9、12、13、15不是都有嫌疑了吗？”

"But there is no accurate criterion for judging now. We have to try once to get the result." Boy No. 13 explained, "If the number sequence chosen for the first time is not valid, it proves that at least one of the seven numbers we chose It is an interference item, and I feel that only after one trial can we add a greater basis for judgment."

3号女生还是气哼哼地不乐意。3号和17号恰巧处于奇数列的首尾两端，如果要剔除掉一个人的话，不是3号就是17号。

Unexpectedly, Sui Li on the 17th would stand up and sell the good old man design in front of other challengers. He said to the girl on the 3rd: "You go first in the first round, and I can wait below. If the test fails, we will try again." Find a way to have other discussions."
