"Are there any other clues besides the butterfly bookmark?" Zhou Ziheng's voice came from there, "There are only three known numbers that can be calculated correctly."

That's right, Xia Xiqing looked around and found a delicate and beautiful conch next to the books. There were several pictures on the wall above the desk. One was a close-up of the photography of sunflowers, and the other was a famous painting "The Vitruvius" that Xia Xiqing was so familiar with.

These seemingly unrelated things caught Xia Xiqing's attention. He stared at the wall intently and suddenly heard Zhou Ziheng's voice.

"Why are you not talking? What are you doing?"

"Looking at a man's naked body painting," Xia Xiqing's eyes were still staring at the portrait on the wall, answering his question seriously, but Zhou Ziheng seemed to be choked and kept coughing. After a while, he stammered again, "Oh, me, there is also a picture on the wall here?"

Xia Xiqing was surprised, and he tried to describe to Zhou Ziheng, "A man with long curly hair stood with his legs together, his hands and feet were just on an external square, and his legs were spread out and his arms were just on an external circle. Is this painting?"

"right."

This is definitely not a coincidence, the similarity of their rooms is really too high.

"Is this painting meaningful?" Although Zhou Ziheng has seen this painting many times, he really does not have much attainment in art, so he can only ask experts in this field.

Xia Xiqing touched the tip of his chin, "It's so meaningful. This painting is a sketch illustration drawn by Leonardo da Vinci for the "Ten Books of Architecture" by the ancient Roman architect Vitruvi. Vitruvi once praised the golden ratio in his book, which also inspired Leonardo da Vinci to draw this human scale sketch. The man inside is also considered synonymous with perfect proportions..."

As he was talking, he felt that some important thought flashed over. Xia Xiqing suddenly stopped and said, "Wait a minute."

He picked up the conch on the table, turned his head and looked at the close-up photo of the sunflower, watching the distribution and arrangement of the seed particles inside.

There is also this famous "Vitruvier".

I see.

"I understand, it's the golden section sequence." Xia Xiqing sat back on the chair calmly, "The conch spirals, the arrangement of sunflower seeds, and this painting are all golden sections."

The fourth number calculated by Zhou Ziheng was also verified, "Is the golden segmentation sequence the Fibonacci sequence right? It seems that I got it right. I just found that 987 is exactly equal to 377 plus 610, so I guess if the last one will be 610 plus 987, which is equal to 1597, but I didn't expect it to be true."

"So other clues are just prompting information." Xia Xiqing put down the conch, "You can try to enter your password."

Zhou Ziheng nodded, and Xia Xiqing's room ticked the ticking sound of entering four-digit passwords. Less than two seconds later, he heard a mechanical voice prompt "The password was successful."

After struggling for a long time, I finally untied one. Although it was not my room. Xia Xiqing was waiting for the good news of success, but Zhou Ziheng replied, "The password is correct, but I can't open the drawer."

"How is that possible..." Although Xia Xiqing knew that they were not in the same room and he had no password lock at all, when he heard Zhou Ziheng say that he couldn't open it, he subconsciously pulled the drawer on his side.

Unexpectedly, it really opened...

This is too weird. Xia Xiqing's tone was full of disbelief. "It's so strange. After you enter the password correctly, my drawer can be opened."

Who knows that the reversal goes beyond that.

Zhou Ziheng replied immediately, "Now my drawer can be opened. Strange."

Hearing Zhou Ziheng muttering to himself, Xia Xiqing thought of his expression of frowning and unable to figure out, and couldn't help laughing, "Maybe you were too young just now."

"Impossible, I really couldn't open it just now."

Maybe it's a problem with the program team, and they are all artificial props, so it's understandable that there are some flaws.

"Stop worrying, let's see what's inside."

Xia Xiqing, who looked down at the drawer, saw the first photo of a group photo. The photo was a couple holding hands in front of the beach. The photo was carefully installed into a beautiful photo frame.

Based on this photo, it is speculated that the owner of the bedroom has a girlfriend.

But why is this kind of photo stuffed in the drawer? Xia Xiqing thought it was not reasonable, but he also knew very well that he could not think too much at this time, so he put the photo frame on the desktop and continued to look through other things in the drawer.

"What have you found?" Zhou Ziheng asked from the other end.

Xia Xiqing casually replied to the photo frame, and then saw a clue that seemed more effective, "I found a notebook, it seemed..." He looked through and found that it had a date written on it, and some short records, "Diary?"

"I also saw a diary, but there was no photo album." Zhou Ziheng continued to exchange the information he had, "There is also a birthday card with a sentence on it."

Just when Zhou Ziheng listed the clues he had obtained, Xia Xiqing had already opened the birthday card first and read out the words above.

"The moment I met you was the beginning of the big explosion. Every particle left me and ran towards you. After that smallest moment, the universe was truly born."

After finishing reading it in one breath, Xia Xiqing suddenly realized that it was about love words between couples. The atmosphere became a little awkward. Xia Xiqing didn't know what to say. It was all like this, so she could only blame herself for being too quick and not being able to blame others.

"Well, then what, are you science students so good at flirting?" In order to relieve the embarrassment, Xia Xiqing asked this question again.

The more you panic, the more likely you are to say the wrong thing. This sentence is really a famous saying. Xia Xiqing, who had just finished asking questions, immediately thought of the picture [Dingdar Effect] that Zhou Ziheng took on the plane before.

Oh no, Zhou Ziheng must have misunderstood that he was teasing him. In fact, he didn't want to talk about the topic in this regard.

I thought Zhou Ziheng couldn't speak, but who knew he even answered.

"It depends on who is right."

Zhou Ziheng's voice didn't sound awkward at all, but was quite calm, which made Xia Xiqing unable to hold on to his face. It turned out that he was the only one who felt embarrassed from beginning to end. Xia Xiqing, who was all in awkward, completely ignored Zhou Ziheng's implicit voice and did not realize that he was the "who" that Zhou Ziheng said.

"Ah, the birthday on this greeting card is October 23. I think this clue may be useful later." In order to preserve his dignity of "winning every battle" in front of this innocent little wolf dog, Xia Xiqing changed the topic very stiffly. Zhou Ziheng also discovered that his unnaturalness was still unnatural, but his frequency could never be adjusted with Xia Xiqing. He only felt that it was his words of private goods that made Xia Xiqing feel pressured. Tweaking the topic was a disguised polite rejection.

Both of them were in circles and still had no idea.

While putting down the birthday card, Xia Xiqing once again focused on the previous notebook. It was a slightly outdated diary. The edges of the diary were worn out and the corners were raised. It seemed that it had been used for a long time. Thinking of this, Xia Xiqing opened the first page.

"Let me take a look at this diary." Xia Xiqing explained to Zhou Ziheng through the radio, and then focused on the diary.

[The weather was sunny on November 11, 2014]

[I originally thought this was my most miserable day. The lonely young man with broken legs spent Singles' Day alone in the hospital ward. Unexpectedly, a new tenant came to this double ward. He was still a super cute girl. She smiled and had a pair of rabbit teeth, like a little rabbit, so cute.]

It was this boy's diary... Xia Xiqing flipped through it quickly and stopped when he reached a certain page.

"Tsk, it took more than six months to catch up..." He looked at the page of the date [May 20, 2015] and couldn't help but talk to himself.

"Have you caught it?"

Xia Xiqing heard Zhou Ziheng’s questions and heard the sound of page turning from the other end, thinking that he must have not seen the back yet, "You are looking too slowly." After that, he flipped back sloppyly again, and accidentally saw one of the diaries saying "She is hospitalized again, hoping that the operation will go smoothly and there will be no more problems."

This girl was hospitalized repeatedly and must have a serious illness.

He suddenly thought of the book on the desk just now.

"The disease his girlfriend had should be...Left Heart Dysplasia Syndrome in the third book. This disease seems to be a congenital heart disease." Xia Xiqing looked through the previous book and tried to find some effective information from it.

"This radio is a gift given to him by the girl." Zhou Ziheng suddenly spoke, "Did you see it?"

"Let's take a look." Xia Xiqing flipped back and turned to the page that Zhou Ziheng said.

[The weather is sunny on May 20, 2016]

[She gave me an old antique and a radio today! She said that this radio was saved up a lot of money for her grandmother when she was young and used to propose marriage. When she was a child, she lay on the radio and listened to stories every day. Now I can imagine the little breast rabbit. Oh, it would be great if she could really travel through time. I want to go back and see what she looked like when she was a child.]

"It turns out that this radio is a prop with a story." Xia Xiqing smiled, "This old antique won't have to witness their marriage, three generations of old ministers."

"No." Zhou Ziheng calmly rejected Xia Xiqing's joke, "Their relationship has something wrong."

"……What?"

"You turn back and count down a few pages."

Xia Xiqing followed Zhou Ziheng's prompt to the last countdown.

[The weather is cloudy on May 13, 2019]

[I had a fight with her today and felt that we hadn't had a good time drinking and communicated with each other for a long time. Why did we get to this point? I really don't understand. Will time really make everything go bad?]

Seeing this sentence, Xia Xiqing suddenly fell silent. Such stories of infatuated men and women emerged one after another every day. They were always beautiful at the beginning. Over time, friction, contradictions, jealousy, and resentment. These negative emotions began to breed and began to grow wildly until they swallowed up all the feelings between the two. The faces that had never been tired of seeing each other became disgusting.

So why start.

The most stable and harmless relationship in the world is that it has nothing to do.

This realistic love story made Xia Xiqing's mood reach a low point. He casually flipped the next few pages and used this method to cover up the turmoil in his heart until his fingers stayed on the last page.

[High rain in May 20, 2019]

[Why should I turn off the phone? Even if I get angry after being misunderstood, I shouldn't turn it off. If I don't turn it off, she won't be emotionally excited and faint. Emergency contact... This card is so ironic. The only time I used it, I actually cut off the contact. The dead person should be me.]

"The girl is dead..." Xia Xiqing didn't expect that this would end, "died from a sudden heart attack."

"Diet..." Zhou Ziheng seemed to have something to say, but he stopped and asked after a while, "So he died without time to rescue him?"

"Yeah." Xia Xiqing put the diary back on the table. He had long passed the age of being moved by this love story. What he was thinking now was what the function of this diary was. According to the arrangement of the script of the previous secret room, every prop in the room did not exist for no reason. Their role can be roughly divided into two categories. One is the clues to launch passwords, but there are too many dates in the diary. If there are no other clues to cooperate, it is unlikely to launch passwords.

Another function is that it is related to the plot of the secret room, or to killer, but this is even more unreasonable. So far, this story is a love story and has no similarity to the suspense murder case in the previous issue.

So what kind of identity should the killer in this issue be?

Xia Xiqing, who was in deep thought, frowned, and there was nothing else in the drawer. He slowly closed his eyes and his eyes fell on the photo frame he had taken out before that he had been pressed upside down on the table.

Only then did he realize that there was a sentence written on the back of the photo frame.

[Return to the correct position.]

The correct location?

This coincides with Xia Xiqing's idea of ​​seeing this photo frame at the beginning. Things like photo frames should have been placed on the table instead of in the drawer. If the information about the male protagonist and the female protagonist quarrel can be explained.

Xia Xiqing picked up this photo frame.

Where should it be placed?

"Do you really have no photo frames? On the table? Or somewhere else." Xia Xiqing, who had no prompt information, had to confirm to Zhou Ziheng again. After all, there were so many similarities in their room, and maybe in his room, the photo frame had been fixed somewhere.

"No, I didn't find any photo frames." Zhou Ziheng's voice was very certain.

At this moment, Xia Xiqing suddenly discovered that in the upper right corner of the desktop, there was a palm-sized rectangular groove on the right side of the laptop. He lowered his head and looked at the edge of the photo frame in his hand, and a somewhat bizarre idea suddenly appeared in his mind.

Could it be...

He tried to place the photo frame in the groove in the upper right corner, and as he thought, the photo frame and the bracket were embedded in it exactly!

"I found the right place." Xia Xiqing breathed a sigh of relief. It turned out that these grooves were useful, but fortunately he felt something was wrong as soon as he came in.

At this moment, the desk lamp actually lit up automatically without warning.

However, this is not the weirdest thing. What he really felt was the next sentence of Zhou Ziheng.

"The photo frame appeared." Zhou Ziheng's voice was full of surprise, and he couldn't even believe it, "Do you know how it came out? Just like a mechanism, a part of the desktop was opened, and the photo frame was pushed up from inside and stood in the upper right corner of the desk."
Chapter completed!
