Ye Yifeng finally spoke: "All close your eyes, let's finish this question quickly."

Zhu Yuhao then grinned and closed his eyes, but did not turn his back.

Mu Yiling, Yan Churan and Guo Zitong couldn't help it.

They also didn't know if Zhu Yuhao was squinting or open.

Only turn your back and quickly undress and take a bath.

Lin Xiao also closed his eyes.

But he didn't want to stay shut up just like that.

Mu Yiling is a school flower, Yan Churan is also good, even if it is Guo Zitong, it is also presentable.

There were three girls bathing together and didn't want to peek, that wasn't a man.

With the help of the water flow, Lin Xiao secretly opened his eyes.

Moreover, Lin Xiao found that others were also peeking.

I have to say that Mu Yiling's figure is simply the most perfect and flawless.

The other two are also very attractive.

The temptation of young girls to the same young boys is irresistible.

The three girls also noticed the boys' small movements, but they had no choice but to turn their backs, quickly wash off the blood on their bodies, and then trot to the locker and start dressing.

The exit has been opened about one person wide, allowing people to squeeze out.

By the time everyone's clothes were changed, the exit had become normal.

When passing through the exit, Mu Yiling said in a low and vicious voice: "Forget everything you just saw, otherwise, I will gouge out your eyes."

Lin Xiao touched his nose: "It's bad, I can't forget it, what should I do?"

Mu Yiling's face blushed, and she viciously glanced at Lin Xiao with her gaze in protest.

Lin Xiao said shamefully: "Your figure is really good, it's not a pad." "

Mu Yiling was defeated.

In this regard, men naturally have an advantage.

She only bowed her head and hurried into the next room after the others.

Lin Xiao smiled proudly, this was the first time he had the upper hand in front of Mu Yiling.

Although not very honorable.

As soon as he entered the next room, Lin Xiao's heart was shocked.

Because, there are people in this room.

No, not people, it's ghosts.

Wise ghost!

The current wise ghosts seem to have changed their temperament, and there is an arrogance that looks down on all living beings.

It looks more threatening than when I was on the school floor.

"Smart brain, meet again." The wise ghost greeted Lin Xiao from a distance.

Lin Xiao felt his scalp numb, he really didn't want to see the wise ghost.

The methods of the wise ghost are too cruel.

He saw with his own eyes that Zhi Ghost directly ate several classmates as small snacks.

Moreover, the current wise ghost seems to be bigger, and the fat body is like a mountain of meat, which is shocking.

This is the basketball court, which indicates that everyone is still in the gymnasium.

"Everyone be careful, this level will definitely be difficult." Lin Xiao said.

Although he had dealt with Zhi Ghost three times, he knew that Zhi Ghost's topic was actually very difficult.

Once the topic of his knowledge blind spot appears, it is finished.

"Smart brain, I heard you." Zhi Ghost held an unknown stick in his hand and chewed it in his mouth, "You're right, this level is not good."

"However, it is not sad either." Zhi Ghost stood up and walked over like a mountain of meat, "After all, there is no punishment for this level, even if you can't answer it, you are just trapped here." Can't die. "

The seven candidates did not dare to speak.

It was visually estimated that the strength of this wise ghost had reached the S level.

Once they angered the wise ghost, several of them were simply not wise enough to stuff their teeth.

Fortunately, Zhi Ghost really didn't seem interested in killing them, and still moved to the edge of the basketball court like a mountain.

Pointing to the basketball court, Zhi Ghost said, "There are seven boxes here, and each box is marked with a number. From one to seven, respectively. And inside the box, there are also seven numbers, also from one to seven. Zhi

Ghost pointed to the seven candidates again: "You also have seven numbers on your backs." Also from one to seven.

Lin Xiao then noticed that everyone had a number on them.

This was just when it was taken out of the locker.

Mu Yiling's is No. 6, and Lin Xiao's is No. 3. Ye Yifeng's is No. 1.

There should be no regularity in the ordering of numbers.

"Your exam questions are also very simple, everyone goes in and chooses three boxes to open, if there is a number that can match the number on your body, you will pass the test. If all seven people pass the level, then go straight to the level.

"If one person fails, start all over again." Remember, every time you do it, the numbers in the box will be randomly arranged. Zhi Ghost looked up at the clock above the gymnasium: "You can discuss freely, and if you have a countermeasure, start clearing the level."

"By the way, there must be no prompts or any sounds, otherwise it will be considered a failure and will start all over again." Zhi Ghost waved his hand, "You can start."

Mu Yiling's face was bitter: "This topic is too difficult, and it all depends on luck." The advantages we have accumulated earlier may be lost at this level.

Zhu Yuhao didn't understand much: "Why?"

Mu Yiling said: "Group A must be the same topic, but they have one less person." With only six boxes, the probability of them passing through is much greater than ours.

"I don't understand." Zhu Yuhao and Guo Zitong both shook their heads.

Ye Yifeng and Yan Churan obviously didn't understand very well, but they didn't say it for the sake of face.

Only Wu Xiaoyao seemed to understand a little.

Lin Xiao spoke: "Let me explain." Each of us can only open three boxes and find a box with the same number as ourselves, with only a three-in-seven chance. And all seven people find the box they want, and the probability is three out of seven to the seventh power.

He took out a pen and calculated it on paper, saying: "Three sevenths is about 0.4, and the seventh power of 0.4 is 0.002, or five hundredths." We experimented five hundred times, and probably only one was correct.

"But Group A is different, each of them has a one-in-two probability." The probability that all six people are correct is 1.5 percent. About five times higher than ours.

"We need to try five hundred times, and they only need a hundred tries to get through." Lin Xiao said a little anxiously, "So, we have to find a way to find a simpler way to pass."

Yan Churan glanced at Lin Xiao: "You are so strange, the ghost list is sparse, the grades are so poor, how can you be so proficient in mathematics, are you stupid?"

Everyone else also laughed and looked at Lin Xiao like an idiot.

In this world, the basic courses of mathematics, physics and chemistry are not important.

Courses related to the thriller exam are the most important.

Lin Xiao also didn't understand something, because his father urged Lin Xiao to study mathematics, physics and chemistry, Chinese and logic since he was a child. This makes Lin Xiao's grades in these courses very good, but the results of the shock exam are worse.
