How to break into a math book

In the end, Su Gechi was persuaded by Tu Hua, and followed him into the level called "Life and Death".

But in fact, this level created by the virus is no different from ordinary levels in appearance. It seems that this should be a prison, and Tu Hua was also put on a blue and white striped prison uniform because of entering the plot.

Only then did Shen Siyi see Tu Hua who had been following behind him, and said in surprise, "Tu Hua?! I thought you..."

After parting ways with Hippahos, the two never met again. Tu Hua explained to him the ins and outs of the matter, including the virus in the game.

Shen Siyi was stunned, he didn't expect that the entrance to the level he discovered by accident turned out to be a trap: "No wonder I always feel that the probability level is a bit strange, the elimination method has become a lot crueler, it turned out to be the cause of the virus!"

Tu Hua nodded: "So this level will not be too easy."

Shen Siyi entered the [Life and Death] level a little earlier than Tu Hua, and he probably understood some of the content of this level: "So far, counting you and me, there are a total of 4 challengers in this level. open."

"This task will definitely not be too easy." Shen Siyi looked down at his prison uniform, "Prison, criminals, this is the closest place to death."

【Ding--】

[Welcome to the most exciting level, life and death are life and death, the mission is about to start...]

The two were discussing, when the system suddenly issued a strange and distorted broadcast sound, announcing the start of the mission.Tu Hua looked up at the entrance, and sure enough, he saw the fifth challenger who entered the level, and this person was a familiar face——Sui Li.

He was tall, and after wearing the prison uniform, he looked more like a gang boss. He saw Tu Hua and Shen Siyi standing together at a glance, glanced at them contemptuously, and then looked away.

The five challengers have already gathered. In addition to Tu Hua, Shen Siyi, and Sui Li, there is also a boy wearing glasses and a thin girl. These two seem to have been battle-hardened and faced prison. The environment remains calm and unruffled.

"What are you five condemned prisoners doing together?" A prison guard suddenly walked out from behind. This man looked fierce and looked more like a criminal than a criminal.

He looked at the few people with gloomy eyes, threw a rusty iron box in his arms on the ground, and said angrily: "The higher-ups decided to lenient the net and give you a few death-row prisoners a chance."

Tu Hua glanced at the tin box that was thrown on the ground, and it turned out to be densely packed with beans. He didn't know what the prison guard wanted to do.

"There are 100 beans in this box. Each of you takes some. The person who takes the most and the person who takes the least will be executed immediately." The prison guard narrowed his eyes. "As for the others... I will let you die for the time being."

"Of course, don't think about surviving in a group. If someone takes the same number of beans, the same person will also be executed."

The prison guard smiled, with a fierce and cruel expression: "Cannibalism...how interesting."

【Ding--】

[Life and death mission rules: 5 challengers take beans from the iron box in order, and the challenger with the most and least beans will be eliminated at the end. It is not necessary to take all 100 beans. When the challenger takes the beans, he can know how many beans are left in the box, but each other does not know how many beans the other party has taken.If several people have the same number of beans in their hands, these people will be eliminated together.Another: The more people eliminated, the more props rewards the remaining survivors can get. 】

As soon as the rules came out, everyone tensed up and looked at others defensively.Shen Siyi raised his eyebrows and said, "This is a bit similar to the [Welfare Level] we first met."

Tu Hua looked up at Sui Li, and couldn't help feeling a little worried: "It's all game theory, but this time it's more cruel than last time."

The system seems to have left time for them to discuss, and has not announced the order of taking beans, which means that they must now think in advance what kind of situation they will face when they are in five different positions.

Tu Hua thinks that the cruelty of this game does not lie in the fixed elimination of the two people, but in the phrase "the more people eliminated, the remaining survivors will get more item rewards", which is what makes the challengers kill each other reason.

No one knows how many beans the other challengers will choose to take, everyone wants to survive and get more rewards based on survival, so it becomes a psychological warfare, only by cheating, lying And count to win.Those who can persist until now know how important rewards are.

Can be painted but don't take it seriously.Others don't know about the virus, but he does.The purpose of the virus program is to make the challengers unable to pass the level and stay in the game. How could it come up with rewards that are helpful to the game?

So once the fighting starts at this level, the virus will be completely fulfilled. All they have to do is to ensure that more people survive.

The thin girl was the first to speak: "If I can get a favorable position when sorting later, I will only try to protect myself as much as possible, and will not harm others."

The boy wearing glasses also agreed: "I think we should discuss how many beans we each take to ensure the lowest casualty rate."

Tu Hua originally thought that Sui Li would be attracted by the rewards, but who knows that he also agreed with this idea of ​​reducing the number of eliminations as much as possible: "There must be two people who will be eliminated, and each of us has a two-fifth chance of being eliminated. The one who got knocked out, so the rules are fair when we don't know the order in which we take the beans."

"The rule says to eliminate the person with the most and the fewest beans..." The thin girl thought for a while and analyzed, "There are a total of 100 beans, and five people divide them, so it is safest to take around 20 beans. Too much or too little is likely to be eliminated."

The man with glasses continued to analyze: "Actually, the first and last picks have the highest probability of being eliminated, because after the first pick has a certain amount, the second pick can be judged based on the remaining beans in the box. How much. So the second person can choose whether to take one more or one less, and other people behind can calculate the average number of beans taken in front according to the remaining beans, and the fate of the first person is fully in control in the hands of others."

"The same goes for the last person. Because there are only 100 beans in total, if everyone in the front gets less, he has more choices at the end, but if the person in front gets a little more, he must be the one with the fewest beans. that."

"What you said is very reasonable, but your analysis requires a very difficult condition." Tu Hua smiled, "It requires each of us to be kind enough and have no revenge."

Tu Hua looked at the man with glasses, and the corners of his lips curled up slightly: "Take the last person who took the beans as an example. If he knew that he would be eliminated, would he do something to pull others into the water?"

"He can completely calculate the most likely number of the first four people, and then take this number himself, and find someone to accompany him to eliminate."

The man with glasses was a little displeased: "Haven't we already reached a consensus? No matter who is the two people who are going to be eliminated, there can be no complaints."

"There are no complaints now, but there is no guarantee that the game will not change after a while." Tu Hua shrugged indifferently.

"Actually, you don't want to cooperate?" Sui Li suddenly stood up, pretending to be on the same line with the man with glasses, "Do you want to eliminate others and get more system rewards?"

The man with glasses also looked at him indignantly.

Tu Hua smiled, his expression still very calm: "Whatever you think, you can even rank out a number now, how about taking the most beans and the least beans for number four and number five respectively? Let's see then, if you I was ranked No. [-] and No. [-], and I will not accept this result so willingly."

Sui Li looked like a messenger of justice, shook his head and said, "I thought we could unite, but I didn't expect that there would still be such wicked people."

The man with glasses gave him an approving glance, and said to Tu Hua: "If you don't want to cooperate, you can just say it directly, and you don't have to go to such lengths to argue with me."

"He's not trying to argue with you." Shen Siyi glanced at Sui Li, and said to the man with glasses, "He just wants to remind you not to reveal too much of your thoughts, otherwise you will be used by some people with ulterior motives."

The man in glasses froze for a moment, frowning in confusion, not knowing what to say or not to say.

Tu Hua didn't care about the attack of the two of them just now, he glanced at Sui Li lightly, and said: "Actually, the current discussion is meaningless, we can't guarantee that the person who draws an unfavorable number will change his mind at all." , I can't even guarantee that if I face elimination, I will be as righteous as I said now."

"Instead of making these useless plans, it's better to think alone." Tu Hua sneered, "Think about what to do if you meet someone who says one thing and does another."

Sui Li knew that Tu Hua and Shen Siyi were mocking him, but in order to win, he didn't make it clear that he would fight with the two of them, but pretended to win over the man with glasses.

Although the man with glasses didn't know these people well, he was not stupid. After Shen Siyi's reminder, he vaguely understood that he seemed to have reservations, and he didn't buy Sui Litao's approaching behavior.

The final result was the part that obviously needed to be discussed, and the five of them did not say a word and meditated alone.The prison guard probably got a little impatient with their quiet atmosphere, and finally announced: "Since you don't discuss it, let's start the game!"

The prison guard took out a stack of number plates from his pocket and prepared to distribute them to the five of them: "The order is not random, this is sorted according to the clearance rate of the main task of the five of you."

Tu Hua thought for a moment, his 2/67 clearance rate is estimated to be at the bottom.While waiting for the prison guard to announce the order, Shen Siyi suddenly walked up to him and said in a low voice, "Tu Hua, thank you for coming to save me."

He looked up at Su Gechi standing in the corner, and his voice suddenly became serious: "For clearing the entire game, you have more potential than me, and it is easier to get Mr. X's help. If it is really hard to make a decision at the end At this critical moment... I will let you live."
