It was Zhou Ziheng's voice. Xia Xiqing, who had left the memories, wiped her face and walked to the carpet before, sat cross-legged. As he expected, the blue button he saw before represented Zhou Ziheng.

"It's hearable." In the moment of responding to him, a guess came to Xia Xiqing's mind, and he immediately asked, "Did you turn that blue knob just now?"

"Yes." Zhou Ziheng answered affirmatively from the other end, "Are there three knobs on your radio? Two red and one blue?"

"Yes." Xia Xiqing stared at the knob, and her thoughts were verified. "I understand. This radio actually assumes the function of a walkie-talkie, but the condition is that two people can turn the knob representing each other at the same time before the signal is turned on." Xia Xiqing sighed, supported the small round table with his elbow, and said lazily 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 turned the topic away, "What is your room like? It seems like a bedroom here, I guess it is a boy's bedroom."

"It seems that my bedroom is also here." Zhou Ziheng turned his head and looked around.

They are all bedrooms? Such a coincidence.

While fiddling with the knob on the radio, Xia Xiqing asked, "Are there letters written under the red knob on your radio?"

"Yes, one is marked 0, and the other is not."

Does everyone have this setting? Xia Xiqing's eyes swept over the row of knobs, reached out and tried to turn the red one next to him. Unexpectedly, as soon as he turned, the sound of the radio blurred again, turning into a murmur without human voices.

The signal is off?

He immediately turned on the blue knob 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 another knob. It seems that this radio can only connect to two rooms at a time. If one of them chooses the knob of the other room, the signal will be interrupted."

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

Xia Xiqing almost without thinking about it, saying that it was not very appropriate, "It's like falling in love, and we have to be in love." As soon as he said this, he felt a little regretful.

Zhou Ziheng didn't say anything for a long time, and Xia Xiqing didn't know if he thought of the bastards he said when he forced him to kiss him that day, just like him.

But he didn't expect that Zhou Ziheng and him did not expect to go together. He was happy for a while for the word "two people are in love" and was a little embarrassed, so he didn't speak.

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

Strangely, this room has no door lock, and there is a square area on the door. Only a small puzzle is embedded in the area, and the rest is blank. Xia Xiqing tried to take down the puzzle with his hands and found that it was fixed on it. But strangely, the fixed edge of the puzzle is also like many items in this room, with a circle of grooves that are closely shaped with the puzzle.

"There should be other puzzles in this room. Could it be to collect puzzles and open the room..." Xia Xiqing said to himself, but Zhou Ziheng spoke at the other end, "Are you talking about puzzles? My room also has puzzles."

"Really?" Xia Xiqing was a little surprised. Judging from the program team's settings for the secret room last time, this was not reasonable, because each secret room in the previous episode had a completely different decryption method, and the prop settings were very diverse. But this time it was different, with so many similarities.

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

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

"Then I found a square blank area on the door of the room. Because the puzzle has two vertical sides, I tried to put it in a while and found that it was just right, and it seemed to be magnetically sucked, so I put it there."

Door?

There was a puzzle piece placed in advance on his door, but Zhou Ziheng needed to put it on himself.

What's going on?

"Did you put the puzzle there? The upper left corner?"

"Yes, the upper left corner can be placed on it."

"Does your puzzle have a circle of grooves?"

"Yes, how do you know?"

“Mine has, too, and a lot of things in this room have grooves.”

Xia Xiqing didn't continue to ask questions. He felt that something had begun to appear, but only a little bit, he knew very well that he must not panic now. Such clues must be accumulated layer by layer to fully understand. Zhou Ziheng just mentioned the desk, and Xia Xiqing felt that there must be other clues on his desk. Strangely, when he walked over to the desk, he found that there was also a butterfly specimen in the drawer of the desk.

The second time a butterfly appeared, it means it was definitely not accidental.

"Do you have butterflies in your room?"

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

Xia Xiqing felt strange, "Do you have drawers on your desk? Are there butterflies on or near the drawers?"

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

Password lock? Xia Xiqing checked his drawer again and found no password lock. He tried to open it and found that the drawer was indeed locked, but there was no lock, nor a lock. He looked at the butterfly specimen sticking to the drawer, thinking whether it was the specimen to hide the keyhole, so he took down the butterfly and found that there was no lockhole, but there were very small words on it.

[Last]

Xia Xiqing looked down at his dark blue top. Thinking of the idea that he had denied it before, maybe he and Zhou Ziheng were really grouped by the program, so their rooms have similar arrangements, but not exactly the same. In this way, the two people may need to cooperate with each other to unlock some passwords in the room.

He tried to verify his conjecture.

"Do you have a few books on your desk?"

Zhou Ziheng's answer was quickly passed, "Well, there are three."

Xia Xiqing counted his books, and it was true, only three books, which seemed to be closer to his idea, "What is the name of the first book?"

"Chaos Studies." Zhou Ziheng also realized something, "So are yours?"

"Yes, that's right." This book "Chaos Science" is the book that Xia Xiqing took out the first butterfly. Fortunately, when he took out the bookmark, he turned the book upside down on the table, so that the page with the butterfly specimen was retained. "I also have this book on my desk, and there is a butterfly bookmark inside. I just took it out."

"Bookmark?" Zhou Ziheng flipped through the book "Chaos Studies" in his hand, and did not flip through any bookmarks from beginning to end. "I don't have bookmarks 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 murmured and repeated the page number that Xia Xiqing said. He found that this chapter talks about the butterfly effect, "Butterfly effect?"

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

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

Although Xia Xiqing was good at math, he was an art student studying liberal arts. He leaned on a chair, flirting with books while laughing and teasing, "Speak human words."

Zhou Ziheng laughed softly, and then patiently explained, "The 'system' we are talking about here is very wide, such as continuous events in timing. For example, when you went out this morning, you were confused about wearing a white shirt or a black shirt, and then you chose the white you like. Usually, after you went out, you would want to buy a cup of coffee and then go to work. But today you were afraid that your clothes would be dirty, so you gave up on the coffee and drove to work as soon as you went out."

Zhou Ziheng tried to explain this complex and mysterious concept in the most simple and easy-to-understand language. "Often 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. But today, you who didn't buy coffee just happened to avoid it. The green light went downstairs of the company. You became the first one to work in the company. The boss happened to have an emergency meeting and had to bring an assistant. He chose you, so you took a plane with your boss to Brazil. As a result, an accident occurred when the plane landed, and you became one of the passengers who died."

Xia Xiqing, who was listening to the story seriously, heard the mystery ending and laughed in anger, "What passengers who died, you really know how to make up the story."

Zhou Ziheng, who was on the other end, also laughed. His slightly low laughter sounded particularly nice in the sizzling electrical signals. "Just give an example, because I'm too lazy to make it up." After saying that, he asked again, "So, have you ever considered what the ending would be if you chose a black shirt that morning?"

If I chose a black shirt...

"I will still go to the coffee shop as usual, be in traffic jams as usual, be late for work, and be specially promoted by my boss to take to a meeting, and I will not take that flight." Xia Xiqing continued to follow Zhou Ziheng's thoughts.

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

Unprepared, the two people blurted out for a moment, and at the same time quoted the most classic quote about the butterfly effect, "A butterfly wing in the Amazon rainforest will occasionally vibrate, which may cause a tornado in Texas, USA in two weeks."

After saying that, both of them were stunned for a moment, and then they started to laugh again.

Zhou Ziheng sighed slightly, "So, it's hard to say which time node choice will make our lives irreversible."

Hearing him say this, Xia Xiqing's mind suddenly had such an idea, he didn't really go to the scene, will everything start?

No, why do you want to sigh?

"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 there is." Zhou Ziheng's tone clearly showed his opposition to this conclusion, although he did not know that Xia Xiqing's words were just used to conceal his distraction. "Chaos is the third physical revolution after relativity and quantum mechanics. These three can be called the three major sciences in the 20th century. The emergence of chaos also subverted people's relatively narrow linear concepts in the past. After all, the countless things in this world cannot be explained by linear correlation, right?"

After hearing what he said, Xia Xiqing's mouth couldn't help but curl up slightly. For some reason, he suddenly felt that Zhou Ziheng was particularly charming at this moment. Whether he was holding a simple example to explain abstract concepts, or he was fighting for the sake of science, he seemed so charming.

smartisthenewsexy. This sentence has been popular for so long, and it was best proved from Zhou Ziheng at this moment.

"You are right." Xia Xiqing's voice was filled with a soft smile.

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

It is a happy thing no matter when you are sure of it. Zhou Ziheng tried to use such a saying to convince the increasingly happy mood at this moment.

"We seem to be getting further and further." Xia Xiqing couldn't help laughing at herself. It was obviously an escape room game, but why did she feel like she was talking to Zhou Ziheng? As he chatted, he couldn't take back the topic. He lowered his head and took the other two books at the corner of the table, and carefully flipped the pages with his fingers.

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

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

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

Xia Xiqing took a look and said, "The page number is 610. It's about the Big Bang theory." After that, he grabbed the butterfly in again and picked up the last and thickest book. Sure enough, there was a butterfly in this book.

"The third book also has a butterfly bookmark, which is sandwiched on page 987. The content of the book is... Left Heart Dysplasia 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 pages may be related. The first book is page 377, the second book is page 610, and the third book is page 987. Are there any other places where butterfly specimens are available?"

Xia Xiqing searched for the desk. There were no other books on the desk except these books, and there were no bookcases in this room.

"Butterfly...butterfly..."

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

"The last butterfly specimen is directly above the desk drawer." A bold guess appeared in Xia Xiqing's mind, "Is the password lock on 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 posted is [last]. Does this mean that this butterfly represents the four-digit password that Zhou Ziheng needs to find.

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

If the signals of the two of them are not connected, wouldn’t they be unable to unlock the password?

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

This program team is really perverted as always.
