"This...what's this?" Zhou Yan was also dumbfounded. He took an envelope and pulled out the contents.

Inside this envelope is an invitation letter.

[Dear Mr. Hirata, and Miss Huazi]

[We sincerely invite two of you to come to "Happy Villa" to experience the comfort of a three-day hot spring vacation]

[This activity is completely free]

The invitation letter is quite delicate, with nice lace printed on the small card.

Zhou Yan turned over the invitation letter again and found the address of "Happy Villa" written on the back.

He blinked his eyes for unknown reasons, and then looked at Jack and Rose.

"You also received the invitation letter?"

Rose nodded, and then drew out the card from the envelope. Sure enough, the Hirata family received exactly the same.

"Hi...? Who gave you this?" Zhou Yan scratched his head.

"Isn't it from your matchmaking agency?" Jack asked.

On the surface, Zhou Yan said that every couple should go home and calm down for three days. Then, these couples received an invitation to a hot spring vacation for three days. It seemed that the matchmaking agency did it.

But only Zhou Yan knew that this three-day cooling-off period was just what he said nonsense.

Just when Zhou Yan was a little bit confused.

Creak~ The door was pushed open.

The one who pushed the door was the receptionist lady who was standing in the hall.

After she entered the door, she walked straight to Zhou Yan, and then stretched out her hand... with a letter in her hand.

"This... is this for me?" Zhou Yan was taken aback.

"Yes." The receptionist nodded.

"Who gave it to me?"

"I don't know, when I went to work today, this letter was on the front desk, and it was written with your name."

"Hiss??" Zhou Yan quickly took the envelope and opened it.

Inside the envelope, it turned out to be an invitation letter.

[Dear Mr. Zhou Yan]

[We sincerely invite you to come to "Happy Villa" to experience the comfort of a three-day hot spring vacation]

[This activity is completely free]

The question marks on Zhou Yan's head are row after row.

"Hey, have all our matchmaking agencies provided this kind of hot spring vacation service?" Zhou Yan asked involuntarily.

The young lady at the front desk shook her head: "It shouldn't have been."

"Then who sent this invitation letter?"

"How do I know?" The young lady at the front desk shrugged and opened the door to go out.

Only a few people in the room were left, staring at each other.

After a while...

"I think this should be the newly launched project of this matchmaking agency." Jack said first.

"But the front desk just said that it's okay. Besides, even if there is such a project, it should be clarified in the invitation letter. It's utterly nagging." Rose frowned. Said very dissatisfied.

at this time.....

"Hey, there seems to be words in the envelope~" Aunt Huazi seemed to be abrupt, and noticed something wrong with the inside of the envelope.

The others were also taken aback, and quickly opened the envelope opening. Sure enough, there seemed to be something written on the inside of the envelope.

Jack is a very neat person, so he tore the envelope open.

I saw the inside of the envelope with two lines written on it, one line on the left and one line on the right.

They are [Jack: Why hasn't he worked hard, but have not been able to succeed? 】

[Ross: It was easy to do it before, but why does it take a lot of effort now? 】

Jack and Rose looked at each other, and they could see that their eyes were full of doubts.

"What's this?" Rose asked.

"Uh... it looks like you are asking a question to both of us." Jack replied.

Rose frowned: "But I don't know what this is asking? It feels like the question is not finished."

Jack also shrugged: "I can't understand either, but..." As he said, he tore the envelope from the middle, and then handed the one with the name [Ross] to her: "Anyway, keep it for now. Maybe it's some kind of trick by this matchmaking agency. If the answer is correct, you will probably win a lottery or something."

"There is no matchmaking agency that draws a lottery during the divorce process." Rose sighed, but she still took the envelope and put it in her pocket.

And watching Jack and Rose do this, the elderly couple Hirata and Huazi also learned to tear the envelope open.

Sure enough, two questions were written on both sides of the envelope.

[Hirata: It shouldn’t be here...]

[Hua Zi: Is the time wrong? 】

Well, these two questions are also confused, but Hirata also followed Jack's way, tearing the envelope in half, and handing the part of Huazi to him.

Next, only Zhou Yan's envelope is left.

He tore the envelope open...The difference from the previous two couples was that there was only one line in Zhou Yan's envelope.

[X2=Y3+? 】

"Fuck?"

Zhou Yan's whole person is not good...because he actually saw a formula!

As we all know, the most terrifying subject in the world is mathematics, and Zhou Yan is obviously a pure-blooded academic scum. When he saw this formula, he could not tear the envelope.

"What's this?" he cried.

No one can give him the answer...and no one knows what the invitation letter is about.

After about half a minute of silence.

"I think, let's go to this hot spring holiday villa?" Rose suggested.

"This..." Huazi hesitated: "Actually, I really want to go. In my life, I haven't taken such a trip even during my wedding and honeymoon."

"Hey, why are you so sloppy? I haven't figured out who sent this letter." Zhou Yan immediately tried to stop it.

but......

"Yes~lightnovelpub.net~ It's free, no matter how you look at it, you should go there." Jack's careless temper didn't listen to Zhou's words at all.

Uncle Hirata smiled: "Detective Zhou, I think you are a bit too nervous, it's just an invitation."

"But, are you not afraid of some villa murders, heavy snow causing us to be trapped in the villa, or the mysterious disappearance of guests?"

"Hey...Although you are a detective, you don't have to think about it so much." Jack smiled bitterly: "The address of this villa is in the villa area on the edge of the city, not deep in the mountains and old forest. Besides, don’t all the killing incidents just appear in the animation.”

"Yeah, let's just relax, and there are no outsiders. How can there be murders? Don't forget, you are a detective. Who wants to kill and invites a detective to follow?" Rose said .
