How to break into a math book

Out of a hundred beans, Sui Li took 20, Shen Siyi took 19, the girl took 22, the three of them took a total of 61, and there were 39 left in the box.

That is to say, if the remaining two people want not to be eliminated, they have to take away the number 21.

In fourth place is the man with glasses.Shen Siyi wanted both himself and Tu Hua to survive, the only possibility was to eliminate the girl who ranked third and the man with glasses who ranked fourth.If the girl chooses the number 22, she has a high probability of being the largest number, so as long as the man with glasses chooses a number less than 19, Tu Hua and Shen Siyi are determined to win.

However, if the fourth place is someone else, Shen Siyi's plan may come to naught.

But this man is a man with glasses.Through the observation of the previous communication session, Shen Siyi discovered that this person was actually not as righteous and selfless as he said.

Tu Hua probably also discovered this, so he came forward to refute him.At the very beginning, he proposed to let everyone discuss a fixed sequence pattern. In fact, the pattern he tried to stipulate was just a template for inferring other people's choices.

That is to say, if a result was really negotiated at that time, then in the actual game, the two people who were drawn in the order to be eliminated can judge how to be safe according to the result stipulated at the beginning.

So this man with glasses is actually not innocent, he just wants to save himself a backhand.However, after being reminded by Tu Hua, he probably discovered that he was not the only one planning to stay behind. The more he revealed, the more information others would get.

In this game, no challenger can stand on the stand of justice, so when Sui Li and the man with glasses questioned Tu Hua's lack of cooperation, Shen Siyi already understood that this man with glasses was actually the same kind of person as Sui Li.He said that solidarity and cooperation will never hurt others. Once he encounters real danger, he will definitely drag others into the water without hesitation.

Sure enough, when the man with glasses found that there were only 39 beans left in the box, his expression was very depressed.After a long time, he suddenly raised his head and looked at Shen Siyi, his eyes seemed to be filled with gloom.

He lowered his head and quickly counted the beans.

As Shen Siyi expected, the man with glasses took 18 of them.

Shen Siyi's hanging heart finally fell to the ground.The man with the glasses was clever but was misunderstood by his cleverness, and his desire for revenge made him dizzy.

在他看到盒子里剩余的39颗豆子时，他已经推算出前三个人所拿豆子数的两种可能：要么是20、19、22，要么就是21、18、22。

First of all, everyone will only take beans that are close to 20. 18 is already the minimum acceptable range of numbers close to 20, and the possibility of duplication of the number of beans of the first three people is basically 0.Because No.2 knows how many No.1 took, the numbers of No.1 and No.2 will never be repeated, and No.3 can easily deduce how many of the top two took, and the number she took is also the same. Will never repeat the top two.

所以在不重复的情况下，唯一可能的就是20、19、22和21、18、22这两种组合。

但他只能判断出数字的组成，并不能准确推算出每个人拿了几个。首先不论No.1拿了几颗豆子，No.2拿的豆子数一定只会比他多一个或者少一个，这是最安全的做法。那么20、19、22这种组合情况就证明No.1和No.2拿的分别是19或20，No.3拿了22。

But there is a strange point in this situation, that is what No.3 thinks.Since the top two got 19 and 20, she can definitely get 21 to ensure safety, and getting 22 is really too jumpy.

This girl is not stupid, so she must have a reason for taking 22, and there must be some reason why she dare not choose the number 21.She is afraid of repeated numbers, so she would rather take the risk and choose a larger number.

问题只可能出现在沈思易身上。如果No.3女生能够确定前两名选的分别是19和20这两个数字的话，她一定会毫不犹豫的选择21，但她并没有选，这就证明他怀疑21这个数字出现过，这就正巧应对了第二种可能性：21、18、22这种数字组合。

也就是说女生其实在怀疑前两名拿的数字并不是19和20，而是18和21，这才让她对18、19、20、21这四个数字都有所忌惮。

No.1's Sui Li will definitely not choose the number 18, because it is two digits away from 20, and the risk is too great, so No.1 can only get 21. The person who deliberately muddies the water is Shen Siyi, who took 18 indivual.

In this way, there are only 39 beans left when it is the turn of the fourth and fifth places, because they cannot be sure whether No. 1 and No. 2 chose 19 and 20 or 18 and 21, so no matter whether he or How to choose Tuhua, either face the maximum and minimum elimination, or may be eliminated by repeating with the previous people.

The man with glasses finally felt that it was unfair. He had clearly agreed not to hurt each other, but the three people in front just irresponsibly threw the blame to the pick behind.

So now no matter which number he chooses, there will be danger.First of all, he made sure that the No.3 girl chose 22, so the number 22 cannot be selected. Secondly, the four numbers 18, 19, 20, and 21 may appear. No matter which one he chooses, he may be eliminated due to repetition.

He cannot choose a number smaller than 18 or larger than 22, but choosing any of the four numbers in the middle is risky.The three people in front of him were tantamount to driving him to a dead end.

Since they are not benevolent, it might as well be a backstop, so the man with glasses decided to choose the number 18.

There are two reasons: First, if someone in the first three people chose the number 18, then that person must be Shen Siyi.For this kind of person who deliberately breaks the rules, it is not a pity to pull him out together.

Second, if no one in front chooses 18, that is to say, if the number combination of the three of them is 19, 20, and 22, he chooses 18, which is equivalent to leaving 21 beans for Tuhua.From Tu Hua's point of view, he will definitely think that the numbers of the previous candidates are too small, so it will be dangerous for him to choose a number above 20, so it is very likely that Tu Hua will choose 17 or 18.

Once he chooses 17, the man with glasses can still get a chance. If he chooses 18, the man with glasses can pull him out together.

The man with glasses is now thinking about breaking the can and breaking the can. Since he is going to die, it is better for everyone to die together, so he has already made preparations for his death. He chose No. 18 and prepared to be eliminated together with Shen Siyi or Tu Hua.

But what he didn't expect was that Tu Hua, who was behind him, took out all 21 beans with ease.

After all the beans were taken away, the prison guard came over with a smirk and announced the number of beans in their hands: "No. 20 is 19, No. 22 is 18, No. 21 is [-], No. [-] is [-], No. [-]... [-]."

Girl No. 21 had expected this result a long time ago, and her expression was very calm. Although guy No. [-] with glasses knew that he would be eliminated, he never expected that Tu Hua would take all [-] of them.He looked at Tu Hua in surprise: "Why do you want to take away all the remaining beans?"

Tu Hua glanced at Shen Siyi and said with a smile, "Because I believe in my teammates."

It was only then that the man with glasses came to his senses. It turned out that both he and girl No. [-] had fallen into the misunderstanding of their thinking. Shen Siyi first deceived No. [-], and then he affected his own judgment because of No. [-]'s judgment, which led to The whole game is lost.

Although the man with glasses was not reconciled, he had no choice but to wait for the system's trial.

【Ding--】

[Challengers Tu Hua, Shen Siyi, and Sui Li passed the checkpoint and got a reward: the collapse of the world. 】

As the system broadcast sounded, the bodies of the man with glasses and girl No. [-] slowly turned into pixel particles and disappeared into the game world.Tu Hua was wondering what the reward of [The Collapse of the World] was, when he felt the ground start to vibrate.

The roof of the entire prison was shaking, and it was about to fall, and the ground not far away also cracked a long crack, as if a giant swallowing beast was about to emerge from the ground.

Sui Li was standing closest to the gap. He grabbed the iron fence on the prison door in horror and shouted in the direction of the prison guard: "The collapse of the world? What the hell kind of reward is this?!"

The prison guard's body was slowly fading, and before disappearing, he showed an inscrutable smile: "I reward you for returning to the abyss that will never see the sun..."

The broken bricks on the top of the head finally fell down with a clatter, and the whole prison was crumbling. Tu Hua hurriedly looked towards the direction of the exit, but found that the aperture at the exit was getting smaller and smaller.

Shen Siyi also hurriedly ran towards the exit: "He is trying to trap us in this checkpoint forever!"

Hearing what Shen Siyi said, Sui Li quickly pushed aside Tu Hua who was standing in front of him, and ran towards the exit with big strides.He was tall, fast, and climbed out quickly.

In the blink of an eye, the exit became smaller, less than one meter in diameter.Shen Siyi followed behind Sui Li, and found that Tu Hua was still behind, wanted to turn around and give him a hand, but Tu Hua yelled at him, "Go out first! Wait for me outside!"

Shen Siyi looked worried: "Can you do it by yourself?"

Tu Hua quickly got up from the ground. His body has been transformed by Su Gechi, and its various functions have been strengthened a lot. Three steps and two steps in parallel, he jumped from the opposite side of the crack. This ravine is less than two meters wide. In fact, it was nothing to Tu Hua, but the moment he took off, the crack opened up like a monster's bloody mouth.

Tu Hua's prediction was wrong, and as soon as his toes touched the opposite stone brick, he lost his center of gravity and fell into the ravine.

At the moment of weightlessness, a firm and powerful hand grabbed him.Tu Hua looked up and saw Su Gechi half-kneeling beside the crack, with one hand on the floor and the other clutching his wrist, with a slightly reproachful expression: "You are too careless."

After speaking, he pulled him up.

Not caring to say anything else, the three hurried towards the exit, Shen Siyi was in front, he climbed up first, and turned around to pull Tu Hua out.

But the moment he jumped out, the aperture of the exit narrowed again, only less than half a meter wide.

Su Gechi had a solemn expression, put his palm on Tu Hua's back, and pushed him out: "Go quickly."

Tu Hua also ran out from the exit in a hurry, but when he was about to turn back to Lasuge Pool, he found that the small exit had disappeared without a trace in an instant.

The plants in the flower bed were lush and lush, Tu Hua knelt on the ground and fiddled with the grass in a panic, the exit was gone, and Su Gechi... was gone too.
