--and many more!

Ji Lu suddenly thought of a question.

There are quite a few teams participating in this "Vatican Flower Fair".

Except for the three teams that seem to have a background in cultivation, the other seven are not proficient in the magic of the Qimen Dunjia.

However, the stages arranged by Yuanchen Palace for the teams that passed the preliminary screening did not seem to be able to be prepared in one night.

Unless these Taoists are really powerful enough to figure out the secrets, it is impossible for them to know in advance which teams are qualifying, and naturally it is impossible to arrange the too difficult and complicated Fengshui skills and Qimen Dunjia in the trial. middle.

Especially the two teams from the Western Fantasy World, if there is no magic spell with translation effect, they are not allowed to even understand Mandarin Chinese.

However, just now, the Wizarding Team really passed the test given to them by Yuanchen Palace.

Ji Xiaoniao quickly recalled the explanations of the two trials he had heard not long ago.

In the first game, the twelve blue sword immortals faced a rather difficult escape from the room.

They must first find the mystery hidden in the mural, and find the missing piece of the puzzle in a certain mobile puzzle mechanism.

Then the sword fairies have to put together a puzzle, open the hidden door hidden behind the mural, and then in the adjacent secret room, from hundreds of bronze sculptures of different shapes, find the golden armor **** who has violated the Tiantiao, and finally knock Only the broken bronze sculpture can finally get the key to open the secret room.

In the second game, the Magic Cube Flip House encountered by the Wizarding Team. Although there is no such a complicated set of interlocking mechanisms, the cube rooms one after the other are very crushing, not to mention that they are constantly changing each other's Location……

Ji Yu thought while reminiscing.

The secret room of the blue sword immortals tested observation and reasoning abilities, which had nothing to do with metaphysics.

Wizards’ Rubik’s Cube requires spatial and three-dimensional geometric analysis, and there is also no entanglement with metaphysics...

Ji Xiaoniao frowned, staring at the floating board on the third circle in front of him.

On the left front of him, there is a blue "Fat", and on the right front, there is a green "Yi".

"...So, what are you trying to test us?"

Ji Lu murmured.

He spoke very softly, but the microphone on his collar still transmitted a few words to other people's ears.

"Little bird, what are you talking about?"

As a high school biology teacher, Mo Tiangen vaguely distinguished the word "test", and was immediately triggered by a sensitive nerve: "You said, this is testing us?"

So Ji Lu told his teammates about his ideas.

"Well……"

After Su Rong listened, she felt that Xiaoniao's idea was quite reasonable.

"Indeed, Yuanchen Palace can't force a group of laymen to use metaphysical knowledge to crack the formation that is too difficult, so this floating board system must have another set of logic..."

At this point, Su Rong stopped talking.

She couldn't think of the mystery.

"These floating boards are numbers except for colors."

Marco stroked his messy blonde hair, and said casually:

"It can't be about adding, subtracting, multiplying and dividing us?"

He does not mean that.

Fan Hemian, who felt that he had vaguely grasped some inspiration from just now, suddenly yelled "Ah".

The four words "addition, subtraction, multiplication, and division" were like a thunderstorm, which immediately smashed her and gave her a start.

The girl's scream was sharp and loud, everyone felt a "buzz" in the earphone, and the tympanic membrane was resonating.

"what happened?"

Bing Xi frowned and asked coldly:

"What are you shouting?"

"and many more!"

Fan Hemian's brain was running at full capacity and high speed, and he was focused on his own speculation, and completely entered a state of non-self that the six relatives did not recognize, and even the attitude of speaking to the boss of the Qinxue Society did not have the usual humility:

"Wait, let me think about it first!"

When everyone heard her tone, they suddenly felt that there was a way.

They knew that this girl was afraid of catching any clues, and immediately closed their mouths and stopped disturbing her.

"...I want to take the risk and do an experiment, can I?"

About a minute later, Fan Hemian's voice came from the headset.

Although the girl tried her best to make herself appear calm and steady, the ending still brought out a little vibrato because of excitement and fear.

Bing Hao asked in a deep voice, "What do you want to do?"

Fan's sister took a deep breath:

"I hope Mr. Bing, you can move once according to my request, so that I can make sure that my thoughts are correct."

Everyone turned their eyes to the direction where the girl was.

The distance is a little far away, most people can't see the expression on Fan Hemian's face, but they can still hear the girl's rapid breathing in the headset.

Obviously, Fan Hemian is actually very nervous.

Now as long as every mistake is made, the number of monsters will double. They are really wrong.

After a brief silence, Bing Hao said, "How sure are you?"

Fan Hemian's hands behind her back clenched tightly into fists, forced herself to calm down, and gave a fairly confident answer: "Seven or eight points."

"Seven or eight points?"

Bing Hao repeated the word again.

He glanced at the hourglass.

This time passed, and now they only have forty minutes left.

"If that's the case, try it."

The white-haired youth retracted his gaze and replied faintly.

Then he walked a few steps quickly and came to the floating board on the second lap, "Which one?"

Fan Hemian was taken aback for a moment, and then he was overjoyed.

"left!"

She quickly replied:

"You go to the "Jiu" on the left!"

Bing Xi took Zero and Su Rong to the third lap of "Jiu".

Everyone waited with bated breath for a moment.

Except that the floating boards on the third circle were all shifted one space to the left, there was no movement of the boards under Bing Hao and their feet.

Everyone breathed a sigh of relief.

"Okay, little girl!"

Marco clapped, "I didn't expect you to be quite good!"

He smiled and asked:

"So, what is going on with these agencies?"

"I think these floating board systems are probably distinguished by prime numbers and composite numbers."

At this time, Fan Hemian said his conclusion.

"Prime numbers are safe, and composite numbers will trigger organs."

A prime number refers to a natural number that has no other factors besides 1 and itself. The opposite composite number is a natural number that can be divisible by other numbers except 1 and itself. This is what elementary school students know Common sense of mathematics.

Someone immediately raised an objection:

"But, the 9 that the boss of Bing Hao just took, it is not a prime number!"

"No, he didn't take ‘9’, but ‘19’. There are actually a hundred numbers here."

Fan Hemian had obviously studied his conjecture carefully in his heart, and immediately replied:

"From the second lap, it is no longer 1 to 10, but 11 to 20, and so on, until the last lap is 91 to 100."

She quickly explained:

"For the few numbers we have tried so far, the 1 and 3 in the first lap are safe, while the 6 and 8 trigger the trap. Then on the second lap, the bird walked at 17, and the ice chairman just walked. 19 is a prime number, so there is no problem, but Mr. Ren's 16 is a composite number, so he stepped on thunder."

Her analysis was well-founded and immediately convinced others.

"In that case, we only need to take prime numbers next, it's okay?"

Mark said as he broke his fingers and counted the prime numbers after hitting twenty, "In this way, this level doesn't seem to be that difficult!"

"No, that's not the case."

Fan Luming, who is also very good at mathematics, immediately figured out the key.

"Although starting from 30, there are seventeen prime numbers, and there are at least two in each circle..."

The Fan brother frowned and looked at the ring of floating boards in front of him, with a solemn expression.

"However, it is difficult for us to ensure that they are in the right place!"

The participants here are not stupid, and soon understood the meaning of treatment in their team.

At this time, Fan Hemian said:

"Give me some more time."

Her voice is determined and confident:

"I will work out the best plan for how to proceed as soon as possible!"

&&&&&&&&&

Just do it, Fan's sister no longer wastes time, immediately turned out a small notebook and a pen, and began to record the position of the floating board for the next eight laps.

With Fan Hemian's height of 1.68 meters, she could only see the embossed words on the three circles of floats in front, but it didn't matter, there was a tall man who was 1.8 meters tall in their group.

So Fan's sister stood directly on the shoulders of Ren Dameiren'er, and from a condescending perspective, she clearly saw the situation of the entire floating board formation.

"Dagen, I have to confirm one more thing, so please move me too."

Fan Hemian directed Mr. Dagen and the others, "You walk up to the second circle on the top of the'Yi'."

According to the girl's judgment, 13 is a prime number, so it is naturally safe.

Mo Tiangen, Ma Ke and the manipulator stepped on the blue floating board "Yi" on the right front in sequence.

Immediately afterwards, the floating board system on the third circle moved one square to the right, and the **** beam of light never appeared.

"really!"

Fan Hemian cheered lowly.

At the same time, holding a pen in her hand, she quickly noted the positions of the remaining eight circles in the notebook.

Then, Sister Fan's sister jumped off Ren Dameiren's shoulders, and directly sat on the floor, wiping the pen like flying, muttering words in her mouth, and quickly calculated the next best plan.

After about three minutes, the girl got the result that everyone had been waiting for.

In order to save time, she didn't sell it, but simply and neatly stated her conclusion:

"If we want to get to the last lap, we have to step on the number three more times at least."

"Bravo!"

When Ma Ke heard this, he rolled his eyes:

"Excellent, that is to say, we have to deal with 64 monsters at last! What a surprising number!"
