My mouth moves faster than my brain; I went viral on Running Man and the whole internet is laughing.

Xu Yan's side.

He took the hamburger and ambrosia with a wry smile, and returned to his room.

After all, this is a product placement from a major sponsor, so we should respect it.

So he carefully opened the hamburger and ambrosio and quickly found the note hidden in the ambrosio straw.

Upon opening it, one would find:

Agents R, I know you'll be imprisoned by Organization Z.

Scientists will arrive at Venue Z in two hours to extract the super-body element from your name tags.

Please find a way to leave prison as soon as possible.

The key is hidden inside the building.

Find the key and open the door to Hall Z to escape.

Xu Yan's lips twitched slightly after reading it.

and so.

Did he just break through the entrance to the newbie village before even accepting the quest?

The live stream chat started scrolling again.

"Hahaha, escape from prison first, then accept the mission!"

"Mission: Escape from prison. Xu Yan: Oh, I just escaped."

Staff member: Sir, please follow the procedure.

"Looking at it this way, Xu Yan is really smart."

"This episode isn't a physical challenge anymore, it's a brain-teasing challenge!"

"..."

Xu Yan put the note away and left the room.

The corridor was quiet.

"It's so quiet, the others haven't come out yet, have they?"

As Xu Yan spoke, he quickened his pace.

He would go into each room he passed and search through it.

According to his speculation, either other guests will play the bad guys in this episode, or there will be an undercover agent within the group.

So he needs to find the key quickly.

But he searched four or five rooms in a row and still couldn't find the key.

Soon, he heard a familiar voice.

"This is so hard..."

"Director, are there any hints?"

"Is there anyone who can save me...?"

It's Reba.

Xu Yan smiled and walked over to the sound.

Reba was sitting on a small stool, holding a piece of paper in her hand, her little face full of worry.

"Help……"

It's easy to tell from Dilraba's voice that she really couldn't solve it.

Xu Yan stood outside the door, hands in his pockets, smiling as he said:

"Beautiful lady, do you need help?"

Reba turned around abruptly, saw it was him, and her eyes lit up immediately:

"Xu Yan! That's great!"

"Please help me, this question is too hard."

As she spoke, Reba happily got up, walked quickly to the door, and handed the test paper in her hand to Xu Yan.

Xu Yan took it and looked at it:

Of the three statements, only one is true.

A: The password is the largest number on the wall.

[B: The password is not the red numbers.]

C: The password is somewhere you can't see it.

After reading the question, Xu Yan looked up at the wall and saw four different colored numbers:

Red: 520, 314, 726

Blue: 168, 403, 917

Huang: 229, 608, 735

Green: 801, 246, 592

There is also a reminder:

[The combination lock will automatically lock for twenty minutes after three incorrect attempts.]

"The password is in here."

"I've already tried twice. If I fail again, I'll have to wait twenty minutes before I can try again," Reba said with a droopy face.

Seeing this, Xu Yan smiled slightly.

He figured out the answer in just two seconds.

So he put his hands behind his back and said with a smile:

"This question isn't difficult, I know how to do it."

"real?!"

Reba perked up and looked at Xu Yan with surprise.

But Xu Yan changed the subject, teasingly saying, "However, if you want me to help you, you'll have to beg me."

"Please?"

"Then you can leave!"

Upon hearing this, Dilraba turned her head away haughtily.

"Okay then."

Xu Yan turned and left.

Dilraba immediately panicked: "Hey, don't go!"

Xu Yan turned around and looked at her with a smile.

Dilraba quickly put on a smile and said, "Please, please."

Xu Yan shook her head: "Your voice isn't sweet enough."

"Xu Yan!"

Reba stomped her feet.

"I'm leaving now, bye-bye."

Xu Yan turned to leave.

"Don't."

Please~

Now, Dilraba even picked up her high-pitched voice.

"That's more like it."

Xu Yan turned her head with a smile.

To be honest, Dilraba's coquettish voice is quite pleasant to listen to; it made his bones melt.

"Hurry up and solve the problem!"

Dilraba continued to act coquettishly.

Xu Yan said calmly, "Actually, this question is very simple."

"If it's A, then B and C are fake. That means the answer is in the red numbers, but the largest one isn't in the red ones, so we can eliminate A."

"If it's B, then A and C are fake, but that's too broad a range. We'd have to choose the correct one from the nine numbers: blue, yellow, and green. Considering the door lock only has three chances to try and solve, it's unlikely to be this one."

"So it can only be C. Just look for numbers in places you wouldn't notice."

After Xu Yan finished speaking, he glanced through the fence gate and looked inside the house.

"Go check under the table or under the chair."

Upon hearing this, Reba immediately did as instructed.

Sure enough, she saw a red number under the stool: 520.

She entered the numbers into the combination lock.

"Click."

The door opened.

"It's finally open!"

Reba breathed a sigh of relief, then immediately went to Xu Yan's side and patted his arm: "Serves you right for bullying me."

Xu Yan smiled and said, "Alright, let's go save the others first."

……

After a while.

The two went up to the third floor together.

As soon as I reached the fourth floor, I heard Chen Chichi's cheeky voice:

Is anyone there?

"Help me!"

Xu Yan and Reba exchanged a glance and quickly walked over.

Chen Chichi was also trapped in the room, looking completely devastated.

"Help! Why do I have to do math problems on this TV show?!"

"The chicken-and-rabbit problem" should really be used to test students, okay? We've already forgotten everything we learned from our teachers.

Just as Chen Chichi was complaining, Chen Chichi and Dilraba appeared.

Chen Chichi's eyes lit up immediately.

"Little Xu!"

"Reba!"

"Come quick, come quick!"

"You two are young, you've only graduated a few years ago, right? You should be able to answer this question."

As he spoke, he handed over the question board.

Xu Yan and Reba took a look:

There are chickens and rabbits in a cage. There are 35 heads and 94 legs in total. How many chickens and rabbits are there?

Reba suddenly felt dizzy and her eyes blurred. She pushed away the question board and said, "I don't understand, I don't understand. I've forgotten everything I know."

Chen Chichi's expression immediately turned bitter.

Xu Yan shrugged: "This question is very simple."

Chen Chichi's expression lit up again: "Great! Quickly calculate it."

"OK."

Xu Yan nodded and murmured, "Let's say the chicken lifts all its legs up."

Chen Chichi: "..."

Dilraba: "..."

Chen Chichi was completely dumbfounded. He wondered if he had misheard: "Wait, Xiao Xu, you're planning to get the chicken to cooperate with you?"

Dilraba couldn't help but laugh and playfully punched Xu Yan's arm.

She thought Xu Yan was making fun of Chen Chichi.

Unexpectedly, Xu Yan said in a serious tone:

"Of course."

"First, have all the animals lift two legs. There are thirty-five heads, so a total of seventy legs are lifted."

"Ninety-four minus seventy equals twenty-four feet."

"The rest are just the rabbit's two extra legs."

"There are twelve rabbits and twenty-three chickens."

As soon as the words were spoken, Dilraba and Chen Chichi were both stunned.

The live chat exploded with activity.
