Li Xiu looked at the black and white buttons, and when there were five seconds left in the countdown, he pressed the black button.

The first button he chose was the black button. Since there was no way to determine the priority for this question, he would determine the priority from the beginning of the trial, which was black.

Although Li Xiu and A Fei had never had such an agreement, Li Xiu believed that A Fei should be able to think of it with his intelligence.

Of course, at this time he could only believe what Ah Fei could think of. Based on his understanding of Ah Fei, she was definitely not a stupid woman.

Staring at the screen, Li Xiu waited for the countdown to end.

"Three... two... one... the countdown is over, the answers are the same, and we will move on to the next round of trials..."

Having passed the trial without any major problems, Li Xiu breathed a sigh of relief. If Ah Fei hadn't thought of it and had relied on luck to choose, both of them would have been doomed.

Even if you don’t die on this question, you will die on the next one as well.

Because according to Li Xiu's own judgment, the following questions will not allow them to cheat so easily step by step.

Sure enough, the next question was beyond the plan they had agreed upon.

"Do you believe in the existence of God? If you believe in it, press either the black or white button. If you don't believe in it, don't press it."

Because Ah Fei said there was only one button, and according to the previous agreement, for questions that were optional, the button needed to be pressed.

But now there are two buttons. If we follow the previous agreement, we must choose one of them, which increases the difficulty.

The best way is to give up. This is the answer that is easiest to reach consensus on. It is the simplest and most brutal way, and it is also the way most people choose to solve the problem.

When faced with a difficult situation that they cannot choose, and there is a possibility of escape, most ordinary people will choose to escape. Even if they know that the situation may develop to an irreversible level, they will avoid the risks they should take.

If both people think this way, it will be easy to reach an agreement.

But Li Xiu chose not to obey, because an agreement is an agreement, and he believed that A Fei would abide by the agreement, instead of simply and crudely thinking that his teammates would give up the difficult choice.

Li Xiu pressed the black button, still following the same thinking as in the previous question, calculating the best option from the very beginning of the trial.

After pressing the black button, Li Xiu narrowed his eyes and stared at the countdown, because he couldn't be sure whether Ah Fei was trying his luck in the previous question, or he really thought of this choice method, or whether Ah Fei had other ideas.

As time passed second by second, Li Xiu's heart beat faster and faster. No matter how strong a person's mentality is, he would inevitably get nervous at this time.

Now Li Xiu can only trust his own judgment, trust his judgment of Ah Fei.

The last number 1 on the light screen turned into fragments and disappeared, but the bracelet on Li Xiu's hand did not explode, which made Li Xiu completely relax.

Through this question, Li Xiu has determined that Ah Fei is just as he judged, not the kind of person who can solve problems in a simple and rough way.

With this kind of tacit understanding, the remaining questions were solved one by one by the two of them, and all ten questions were perfectly consistent.

Through these questions, a feeling arose between Li Xiu and A Fei. With this feeling, it can even be said that both of them are the people who understand each other best in the world. Not even blood relatives or lovers can understand each other's thoughts as well as they do.

The last question appeared on the screen, and the cold electronic voice read out the question word by word.

After reading the question, Li Xiu hesitated for the first time.

The questions are simple and the choices are clear. Even if two people do not know each other at all, they can make the same choice, allowing both of them to survive and get the reward.

Choose to press the black button, and both of them can complete the Trial at the Ends of the Earth and get the rewards they deserve.

But besides this option, there is another choice.

If one person chooses to press the white button and the other presses the black button, the person who chooses to press the white button will get double the reward, while the person who chooses to press the black button will fail the trial.

Beyond that, there are no rules that say what happens if both people press the white button.

Li Xiu looked at the black and white buttons, but did not press them as decisively as before. Such a simple multiple-choice question was a hundred times more dangerous than the previous ones.

If according to the agreement, Li Xiu should press the black button.

But when Ah Fei participated in the Haijiao Tianya trial for the first time, she survived and obtained the S-level skill reward "Abstention".

The Haijiao Tianya trial requires two people to form a team to participate, which means that there must have been one person who teamed up with A Fei to participate in the trial.

What about the other person? He must have gone to the last step with the bandit, otherwise the bandit would not have received the reward.

But what about the person who teamed up with Ah Fei? If he survived, he should have obtained S-level skills. Why didn't we hear about such a person in the Abyss Base?

If there really was such a person, Lao Gu would never let him go, just like what Lao Gu did to A Fei.

What’s even more terrifying is that Ah Fei told Li Xiu that there were ten questions in total, but now there are eleven questions, and the extra question is a multiple-choice question.

Is there a possibility that Ah Fei already knew that the question was eleven, and the trial she participated in before was also the same multiple-choice question, and the person who teamed up with Ah Fei chose the black button, but Ah Fei chose the white one?

Looking at the black and white buttons, Li Xiu remained silent.

If two people press the white button at the same time, it means the trial has failed. Perhaps a smart person like Ah Fei would choose the black button.

But the rules do not specify what will happen if both people press the white button. Perhaps by pressing the white button, both people can get double the reward.

This idea is dangerous, but it is not impossible. It is because of this small possibility that the probability of people who might originally choose the black button to choose the white button becomes higher.

If you choose the black button, there is a 50% chance that you will die. Even if you don't die, you will only get one reward.

If you choose the white button, you may not have to die, and you have a 50% chance of getting two rewards, or even more than a 50% chance.

When choosing between angels and demons, the demon is often more attractive.

Li Xiu didn't care about an extra reward, but what about Ah Fei? After all, they had only known each other for half a month, and Ah Fei might be a criminal.

"Four...three...two..." The countdown has reached the last second, and it is time to make a choice.

"The difficulty of S-level is indeed well-deserved. In the face of reality, the ugliness of human nature often defeats kindness. Ah Fei, what will you choose?" Li Xiu looked at the two buttons in front of him, slowly exhaled from his chest, and reached out to press one of the buttons.
