Zhou Yan looked confused and even turned the envelope on his hand to look at the back...

"Where is an ellipse..."

A hint of embarrassment flashed across Liu Zhiyuan's face.

"Brother Yan...you are not very good at math."

"Not good, what's wrong?" Zhou Yan replied shamelessly.

There is nothing to despise. Isn’t it normal for bad mathematics? Those who are good at math are freaks.

However, our Liu Zhiyuan is really a freak.

Maybe everyone has forgotten that this guy belongs to the [Probability Detective Agency]!

The people in this detective agency are all a group of freaks. They firmly believe that mathematics can solve any problem, including solving cases.

This also leads to the fact that the people in this detective agency have almost no friends in the detective industry, because most people don’t know how they solved the case, can’t help or get in touch, and people can understand what they say.

"Uh... the formula you wrote on paper is an ellipse." Liu Zhiyuan said: "But it can't be said to be an ellipse. It should be said that it belongs to the [Fermat's Theorem]. It is a very difficult problem in mathematics, almost as famous as the Goethebuck conjecture..."

"Stop and stop!" Zhou Yan shouted quickly: "Stop talking, I admit defeat, I just want to know now, what does this thing mean?"

"Nothing means nothing." Liu Zhiyuan spread his hands.

"Uh..." Zhou Yan was speechless.

So now... I have eaten and found the room, and it seems that nothing has happened. I feel that this trip was really an ordinary vacation. The rest of the people suggested going to the hot springs.

Then everyone received a response!

Except for Zhou Yan.

He still tried his best to stop everyone from running around, but now the intensity of his speech has no effect at all. The rest of the people went back to their rooms to change their clothes, leaving Zhou Yan alone, in the huge villa building, looking depressed.

This invitation was so strange. It clearly felt that something was going to happen, but nothing happened... Zhou Yan sat on the sofa helplessly, and could only flip through the notes, trying to find some clues.

【Captain Poison: A chef who doesn't want to be a nanny is not a good detective】

"Uh~ Is this a mockery of Liu Zhiyuan? He is still a math freak~"

[Clayale: Good guy, where you live is a soft meal, where you go to work is a soft meal]

"Hey? What are you saying? Retract me, let me get rid of it! Do you want to get involved in my Zhou detective team?!"

[I don't think of a human being: Do you understand why it is an oval? The liberal arts student was confused]

"Ha, who knows why it is an ellipse? Even if someone explains it, I probably won't understand it. What's more, what else is [Fermat's Theorem]? Who knows what these are?!"

【The quilt is flying: This is an elliptical function…】

"Damn it? Are there any math freaks in this book? It's so scary."

[10 yuan 2 jin jasmine squid: If? is a constant, then the image is like this]

"Stop! Stop and stop! Stop talking, I can't understand all the questions about mathematics!"

Zhou Yan closed the book and knew his abilities very well. Even if he really became a Sherlock-level detective one day, then wouldn’t it be math or not!

And just then...

"Ahhhhhh————" A scream! It came from the hot spring area in the backyard!

"Damn!" Zhou Yan jumped up from the sofa. Sure enough, something happened!

Zhou Yan didn't dare to delay for a moment, so he rushed to the backyard quickly.

Because the sound of shouting just now was a woman, Zhou Yan also ran directly to the Ladies' Hot Spring Area.

[Receive red envelopes after reading books] Follow the public account [Book Friends Base Camp], and you can get a maximum of 888 cash red envelopes after reading books!

There is no door in this hot spring area, just a curtain is blocked. Zhou Yan rushed in without thinking. Now that something has happened, he can't care so much!

However... he never expected that as soon as he rushed in, he saw three people, [Sister Huazi], [Ms. Rousi], and [Xiaomei], and nothing happened, just soaking in the hot spring.

For a moment, three women and one man looked at each other...

"Ahhhhhh————" Another sharper shout!

"Yes, yes, yes, yes, sorry! I didn't see anything!" Zhou Yan hurried out of the hot spring.

......

Ten minutes later, everyone sat on the sofa in the hall, and Zhou Yan sat in the middle, feeling embarrassed.

"I really rushed in after hearing someone shouting. I'm not a hooligan!" Zhou Yan explained.

"I said Mr. Detective, are you a little too nervous? There are no outsiders in this villa. Why do you always think this is a trap?"

"Because the invitation is really unknown." Zhou Yan said.

"But it turns out that there is no danger here. I think it is probably an activity you made in your matchmaking agency, but you won't know." Rou Si said angrily.

"Oh..." Zhou Yan also sighed: "Okay, anyway, you were all soaking in the water, and I didn't see anything, so..."

"Hey! You still said?!" Jack was also very depressed!

"I'm sorry, I won't say it." Zhou Yan waved his hand quickly: "But I still want to ask why you were shouting at that time."

"Because you are in, of course I have to shout!" Rou Si said.

"No, no, no, I mean the previous one. I heard your screams, so I rushed in."

"Oh, you said it was the first time." Rose said, "Because I stepped on something in the hot spring, it was so slid, so I called out."

"What?" Zhou Yan suddenly became interested.

"A wooden board looks like a decoration hanging on the wall. When I came out, I put the thing on the table." Rou Si pointed to a small table at the entrance of the hall.

Zhou Yan quickly got up and walked over, and found that there was actually a square wooden board on the table.

"This thing is in the hot spring pool?"

"Yes!" Rou Si said.

Zhou Yan frowned, and saw that the surface of the wooden board was very smooth, a bit like a photo frame. Then, he turned the wooden board over again.

"Huh?" Zhou Yan was stunned for a moment, because he found that there were words behind the wooden board.

But he couldn't understand those words, either in Chinese or in English!

"What's wrong?" Liu Zhiyuan came over and saw the words behind the wooden board: "Huh? What is this written?"

When the rest of the people saw the expressions of the two detectives, they all came over curiously.

"Is this...is this a kind of text?"

"I can't understand at all."

Everyone said that they couldn't understand what was written on it at all.

And just then...
Chapter completed!
