It was Zhou Ziheng's voice. Xia Xiqing, who was out of memory, wiped his face, walked to the previous carpet and sat down cross-legged. As he expected, the blue button he saw earlier really represented Zhou Ziheng.

"Audible." The moment Xia Xiqing responded to him, a guess appeared in his mind, and he immediately asked, "Did you also turn that blue **** just now?"

"Yeah." Zhou Ziheng's affirmative answer came from the other end, "Is there also three knobs on your radio? Two red and one blue?"

"Yes." Xia Xiqing stared at the knob, and the thoughts in his heart were verified, "I know, this radio actually assumes the function of a walkie-talkie, but the condition is that two people must rotate the **** representing each other at the same time to connect to the signal. "Xia Xiqing sighed, leaning on the small round table with his elbows, and lazily said to Zhou Ziheng on the other end of the walkie-talkie, "I have been waiting for you for a long time."

Zhou Ziheng on the other end felt his heart pounding when he heard this, but before he could think of what to say, Xia Xiqing changed the subject again, "What is your room like? My side seems to be a bedroom, I guess It's a boy's bedroom."

"My side seems to be the bedroom too." Zhou Ziheng turned around and looked around.

All bedrooms? Such a coincidence.

Xia Xiqing fiddled with the knobs on the radio and asked, "Are there letters written under the red knobs on your radio?"

"That's right, one is marked with 0, and the other is not."

Do all of them have this setup? Xia Xiqing glanced at the row of knobs, stretched out his hand and tried to turn the red one next to it, but as soon as he turned it, the sound of the radio became blurred again, turning into a noise without human voices.

The signal is broken?

He immediately turned on the blue **** and turned off the red one, and Zhou Ziheng's voice reappeared: "What happened just now? Suddenly there was no sound."

"I just turned on other knobs. It seems that this radio can only connect up to two rooms at a time, and if one of them selects the **** in the other room, the signal will be lost."

"The threshold is really high." Zhou Ziheng joked.

Xia Xiqing brought up an inappropriate metaphor almost without thinking, "It's like falling in love, you have to be happy with each other." As soon as he said this, he himself regretted it a little.

Zhou Ziheng was silent for a long time, and Xia Xiqing didn't know if he thought of the stupid things he said when he kissed him that day like himself.

But he didn't expect that Zhou Ziheng and he didn't want to go together. He was happy for a while because of the word "two love each other", and he was a little embarrassed, so he didn't speak.

The atmosphere was suddenly awkward, Xia Xiqing stood up and walked around the room, trying to give each other some space.

The strange thing is that there is no door lock in this room, and there is a square area pasted on the door, only a small puzzle piece is embedded in the area, and the rest are blank. Xia Xiqing tried to remove the jigsaw piece with his hands, but found that it was fixed on it. But the strange thing is that the edge of the fixed puzzle, like many items in this room, has a circle of grooves that fit the shape of the puzzle.

"There should be other puzzles in this room. Could it be that all the puzzles are collected to open the room..." Xia Xiqing said to himself, but Zhou Ziheng spoke at the other end, "You mean puzzles? I also have puzzles in my room."

"Really?" Xia Xiqing was a little surprised. Judging from the setting of the secret room by the program group last time, this is not reasonable, because each secret room in the previous episode has a completely different decryption method, and the props are also set very differently. diversification. But this time is different, there are so many similarities.

"Well, I found a puzzle in the book on the desk just now, but this is the only piece. I searched for a long time at the beginning but couldn't find a suitable place to put the puzzle."

The more Xia Xiqing heard it, the more strange he became. He walked to the desk in his room as Zhou Ziheng said, "And then?"

"Then I found a square blank area on the door of the room, because the puzzle has two vertical sides, I tried to fit it, and it just fit, and it seemed to be magnetic again, so I put it there. "

Door?

There is a jigsaw puzzle that has been placed on his door, but Zhou Ziheng needs to put the jigsaw puzzle on it himself.

How is this going?

"Where did you put the puzzle? Top left?"

"Yes, the upper left corner just fits there."

"Is there a groove around your puzzle too?"

"Yes, how do you know?"

"Mine has it too, and a lot of things in this room have grooves."

Xia Xiqing didn't continue to ask questions. He felt that something was beginning to emerge, but only a little bit. He knew very well that he must not panic now. This kind of clues must be accumulated layer by layer before they can be fully understood. Zhou Ziheng just mentioned the desk, and Xia Xiqing felt that there must be other clues on his desk. The strange thing is that when he came to the desk now, he found that there was also a butterfly specimen in the drawer of the desk.

Butterflies appeared for the second time, which means it was definitely not by chance.

"Are there any butterflies in your room?"

"Butterflies?" Zhou Ziheng's voice was obviously puzzled, "There are no butterflies."

Xia Xiqing felt strange, "Does your desk have any drawers, and are there any butterflies on or near the drawers?"

Zhou Ziheng lowered his head and checked, "There are drawers, but no butterflies. But there is a four-digit combination lock."

password? Xia Xiqing checked his drawer again, but found no combination lock. He tried to open it, and found that the drawer was indeed locked, but there was no keyhole or lock. He looked at the butterfly specimen pasted on the drawer, thinking that the keyhole might be hidden by the specimen, so he took the butterfly out and found that there was no keyhole, but there were a few small words written on it. Character.

[the last one]

Xia Xiqing looked down at his dark blue shirt, thinking of the idea that he had rejected before, maybe he and Zhou Ziheng were really grouped by the program, so their rooms had some similar layouts, but not completely. Similarly, in this case, two people may need to cooperate with each other to unlock some passwords in the room.

He tried to verify his conjecture.

"Are there any books on your desk?"

Zhou Ziheng's answer came quickly, "Well, there are three books."

Xia Xiqing counted his books, and sure enough, there were three books, which seemed to be closer to his idea, "What's the name of the first book?"

""Chaos Science"." Zhou Ziheng also realized something, "Your too?"

"Yes, that's right." This "Chaos Science" is the book in which Xia Xiqing found the first butterfly. Fortunately, when he just took out the bookmark, he turned the book upside down on the table, making the one with the butterfly specimen in it Pages are preserved, "I have this book on my desk too, and there's a butterfly bookmark in it that I just took out."

"Bookmark?" Zhou Ziheng flipped through the "Chaos Science" in his hand, but he didn't find any bookmarks from the beginning to the end. "I don't have a bookmark in this book. On which page did you see it?"

Xia Xiqing turned the book over and looked at the page number, "Page 377."

"Page 377..." Zhou Ziheng repeated the page number that Xia Xiqing said in a muttered voice. He found that this chapter was about the butterfly effect, "Butterfly effect?"

"Yes, it is about the butterfly effect. It seems that our books are exactly the same." Xia Xiqing felt a little strange, "Does Chaos (chaos) belong to physics? I don't know much about it."

Zhou Ziheng gave an affirmative answer, "Well, more precisely, it belongs to deterministic dynamics. The concept of chaos means that the overall evolution of a system is largely determined by the initial state, or sensitive to the initial state."

Although Xia Xiqing is good at mathematics, he is an art student majoring in liberal arts. He leaned back on the chair, flipping through the book while laughing and teasing, "Speak human."

Zhou Ziheng gave a low laugh, and then patiently explained, "The 'system' we are talking about here has a wide range, such as sequential events in time series. For example, when you went out this morning, you were struggling with whether to wear a white shirt or not." Black shirt, and then you choose your favorite white, usually you want to buy a cup of coffee and go to work after you go out, but today you are afraid of getting your clothes dirty, so you give up the coffee and drive directly to work as soon as you go out.”

Zhou Ziheng tried to explain this complex and mysterious concept in the most easy-to-understand language, "Usually the time you buy coffee will cause you to miss the best time to avoid the morning rush hour, so you often encounter traffic jams. Today, I didn't buy coffee. You just avoided the coffee guy, and you drove all the way to the downstairs of the company with a green light. You became the first one to go to work in the company. It happened that the boss had an urgent meeting and had to bring an assistant. He chose you, so you and the boss Flying together to Brazil, there was an accident when the plane landed, and you were one of the passengers who died."

Xia Xiqing, who listened carefully to the story, heard the ending of the mystery, and laughed angrily, "You really know how to make up what happened to passengers who died."

Zhou Ziheng on the other end also laughed, his slightly low-pitched laughter sounded particularly pleasant amidst the buzzing electrical signals, "It's just an analogy, because I'm too lazy to make it up." After speaking, he asked again , "So, have you ever considered how it would have ended if you had chosen a black shirt that morning?"

If I choose a black shirt...

"I will still go to the coffee shop as usual, get stuck in traffic as usual, and be late for work, and I won't be specially promoted by the boss to take me to a meeting because of this, so I won't get on that plane." Xia Xiqing followed Zhou Ziheng's train of thought. .

"It is likely to be so. This is what I said. In the theory of chaos, the evolution of the system is very sensitive to the initial state. You can think of 'wearing a white shirt' and 'wearing a black shirt' as two different initial states. They may affect the development of a series of subsequent events." Zhou Ziheng added, "The butterfly effect is an important part of chaos."

Unprepared, the two blurted out for a while, and at the same time quoted the most classic quote about the butterfly effect, "An occasional vibration of the wings of a butterfly in the Amazon rainforest may cause a tornado in Texas, USA in two weeks."

Both of them froze for a moment, then laughed again.

Zhou Ziheng said with a little sigh, "So, it is uncertain which time node the choice will make irreversible changes in our whole life."

Hearing what he said, Xia Xiqing had such an idea in his mind, if Xu Qichen hadn't given him the VIP ticket for the film conference at that time, and he hadn't actually been to the scene, would everything have started?

No, why should I be emotional.

"What’s wrong with you?"

Xia Xiqing came back to his senses, "It's nothing, I just don't think there is any need to think about this kind of thing."

"Of course." Zhou Ziheng's tone clearly showed his opposition to this assertion, although he didn't know that Xia Xiqing's words were just to cover up his distraction, "Chaos is the third physics science after relativity and quantum mechanics. These three can be called the three major sciences of the 20th century. The emergence of chaos has also subverted people's relatively narrow linear concept in the past. After all, countless things in this world cannot be explained by linear correlation, right? ?"

Hearing his words, the corners of Xia Xiqing's mouth turned up slightly. For some reason, he suddenly felt that Zhou Ziheng was extraordinarily charming at the moment, whether he was explaining abstract concepts with easy-to-understand examples, or at the moment for scientific evidence. He looks so attractive even though he strives hard.

Smartisthenewsexy. This sentence has been popular for so long, and at this moment, Zhou Ziheng got the best proof.

"You're right." There was a soft smile in Xia Xiqing's voice.

Such emotions were obviously weakened by the signal, but they still fell heavily into Zhou Ziheng's ears.

It is always a joy to be recognized anytime. Zhou Ziheng tried to use such rhetoric to convince the increasingly joyful mood at the moment.

"We seem to be getting further and further away." Xia Xiqing couldn't help laughing at himself. It was obviously an escape room game, so why did it feel like he was on the phone with Zhou Ziheng, and he couldn't pick up the topic while chatting. He lowered his head and took the other two books from the corner of the table, flipping the pages carefully with his fingers.

Sure enough, there is also a specimen of a small butterfly in this book.

"I found another specimen of a butterfly, in the second book."

After a while, Zhou Ziheng's voice came from over there, "I still haven't seen any butterflies in my book. What's the page number of the second book, and what's in it?"

Xia Xiqing took a look, "The page number is 610. It's about the Big Bang theory." After speaking, he put the butterfly in again, picked up the last and thickest book, and sure enough, this one There is also a butterfly inside.

"There is also a butterfly bookmark in the third book, which is on page 987. The content of the book is... left heart hypoplasia syndrome? Strange, this person's reading range is really wide, from chaos to the universe, from the universe to human pathology .”

Zhou Ziheng's intuition told him that it should be related to numbers, "These page numbers may be related. The first book is page 377, the second book is page 610, and the third book is page 987. There are other Where is the stuffed butterfly?"

Xia Xiqing rummaged through the desk, but there were no other books on the desk except these few books, and there was no bookcase in this room.

"Butterfly...butterfly..."

He suddenly thought of the butterfly specimen he saw on the drawer just now.

"The last butterfly specimen is directly above the desk drawer." Xia Xiqing had a bold guess in his mind, "Is the combination lock of your desk also directly above the drawer?"

"That's right."

That's right.

The first butterfly corresponds to the first book, the second butterfly corresponds to the second book, and the third butterfly corresponds to the third book, so the place where the last butterfly is written [last], does this mean That is, the butterfly represents the four-digit password that Zhou Ziheng needs to find.

"So, the four-digit password for your drawer may need to be deduced from the clues suggested by the three butterflies in my room."

If the signals of the two of them are not connected, wouldn't it be impossible to unlock the code?

This is probably a new way for the director to hype CP. As long as they choose each other, they will have the opportunity to unlock the password, which forces the two to cooperate in different rooms.

This program group is really as perverted as ever.

The author has something to say: Program director: Two handsome guys, we invited you to record the program and decrypt it, not to talk on the phone and fall in love, OK? There is no tension at all.

Recently, the exam week is approaching, and I have also started to get busy (yes, graduate students can’t escape the final exam, although they are all doing projects and pre), old readers should know that I am naked, and the pressure is relatively high these two days, but in I am trying my best to adjust, so the word count may be reduced (only temporarily).

As for Xia Xiqing's personality: I don't want to wash away the fact that his previous life style was that of a playboy, but this does not prevent the cutie in the comment area from feeling sorry for him. I don't think the two conflict. Of course, if there is a cutie who really can't stand his previous love history, it doesn't matter if you can abandon the article.

Also, whether it's Zhou Ziheng or Xia Xiqing, I feel sorry for my son, and so do you, and you can love whoever you want. I also often play misery contests with readers in the reader group to see who is the worst among the current four sons.

My consistent character setting style is to prefer flawed characters, Xia Xiqing and Xu Qichen are typical representatives. And to be honest, Xia Xiqing didn't really hurt Zhou Ziheng, he would stop decently when he was rejected, and he would definitely fail if he didn't have the overlord to force his bow.
