Xia Xiqing calculated quickly and understood immediately, but before he could speak, Zhou Ziheng, who was still looking at the computer page, took the lead.

"This is the number of four-leaf roses."

Xia Xiqing crossed out the question mark on the draft with a pen, and wrote a number at the end of the equal sign—1634.

No, how did he do it?

"That's right." He raised his eyebrows, and looked at Zhou Ziheng with some surprise, "You knew it was the number of four-leaf roses without counting?" Didn't he study physics, and he is so good at mental arithmetic?

Zhou Ziheng pointed to the computer, "Look at the roses on this page."

Shang Sirui, who is naturally incompetent in calculations, has been following Zhou Ziheng to look at the computer page, and he also discovered the secret, "Oh! The roses on this are all copied and pasted. They are all the same in length and only have four leaves. I said it's weird." Soon, a puzzled expression appeared on his delicate face, "But... what is the number of four-leaf roses?"

Xia Xiqing pointed to the formula on the draft paper, "This is very clear. You see, 1634 is a four-digit number. After adding the 4th power of each digit, it is equal to 1634 itself. This is the four-leaf rose. Number. In fact, it is a self-power number of four digits."

Shang Sirui nodded half-understood. Seeing that the two people already knew the type of this number, he suddenly became happy, "Then the last two numbers are also the number of four-leaf roses, right? Then can they be filled out now?" gone?"

The kid is too optimistic. Xia Xiqing felt a bit of a headache, he turned the pen subconsciously, and gave a straightforward negative answer, "I can't." After finishing speaking, the pen in his hand stopped, and his eyes looked at Zhou Ziheng, "Do you know what is in the four-digit number? Does the four-leaf rose count?"

Zhou Ziheng shook his head, "I only know there are three."

He studied physics, not mathematics. Probably only mathematicians who are too busy to study numbers every day know.

Who has nothing to remember this, Xia Xiqing sighed, he became very restless when encountering such things that required patience, and tapped the pen tip on the paper, "So what should we do now? Exhaustive?"

"Is it exhausting until the end of this season of the show?" Zhou Ziheng laughed at himself unceremoniously, "The violent solution method won't work at this time, right?"

"What are you trying to solve violently?" Shang Sirui rubbed his cheeks frantically with a dazed expression on his face, "What kind of fairy tales are you guys having, obviously they are all in Chinese, why can't I understand a single word?"

Xia Xiqing laughed, and he pinched his long forehead hair behind his ears, "Anyway, it's almost impossible to calculate this by hand, so it doesn't matter whether you understand it or not."

"If I knew that going to this show was so troublesome, my manager would have turned me down a long time ago." Shang Sirui has a very familiar personality, with his hands on Xia Xiqing's shoulders, he smiled so hard that he couldn't see his teeth, he was a bit of an idol. There is no burden, "After all, I am an idiot."

This kid is also funny, Xia Xiqing has always used the gentle knife in the love field, and it has become a habit after a long time, he turned his face to look at Shang Sirui, smiled and corrected his definition of himself, "Correct it. Even if it is, she is still a straw bag beauty."

"Oh~~" Shang Sirui hooked his neck, and the two leaned extremely close together, "But I think you are more beautiful than me hahaha..."

Seeing the two of them hooking their shoulders together, Zhou Ziheng felt numb all over. On the one hand, he developed a deeper disdain for Xia Xiqing, and on the other hand, he was a little worried about Shang Sirui, a heartless second idiot.

The expression and tone of Xia Xiqing's words to him just now, in Zhou Ziheng's opinion, could be considered flirting. Xia Xiqing is simply poisonous, his eyes are watering when he speaks, and he is full of smiles, no matter who he is with.

Could it be that he fell in love with Shang Sirui? This thought also scared him, Zhou Ziheng frowned, coughed, and diverted everyone's attention, "I think we must have missed some important clues. The team will not embarrass the guests so much, it is basically impossible to do it with hands."

Xia Xiqing nodded in agreement. The program team will not embarrass the guests, especially Shang Sirui, the original player in this room. disconnect.

But he doesn't like this kind of thing that needs to be solved violently. It is calculated one by one and repeated thousands of times. This kind of low-level work has long been done by humans. Thinking of this, he couldn't help laughing, "Hey, if my nephew It would be great if it was here, the number of four-leaf roses and the number of daffodils are classic examples for their programming introduction, and they have compiled so many times, maybe they have memorized these numbers long ago."

"Wow, your nephew? How old is your nephew, he started to learn programming, your family is all gods..." Shang Sirui still put his arms around Xia Xiqing, half of his body was hanging on him.

As soon as the casual mention was finished, Xia Xiqing woke up in an instant. He turned his head to look at Zhou Ziheng, and found that Zhou Ziheng who was sitting on the chair was also looking up at him, and a strange tacit understanding began to form between the two of them again.

Zhou Ziheng manually moved the mouse, closed the initial interface, and checked the computer desktop and some folders.

Xia Xiqing said to himself, "I shouldn't be able to find it this way...there must be a writing path..." He walked back to the wastebasket before.

"Hey, what are you doing?"

"There may be a clue."

One by one, he looked through the waste papers they sorted out, some of which were written with irrelevant words, and some were waste papers drawn by children, until he found a piece of paper with only one line written on it.

As he expected, it was a path in the computer.

"It's under the D drive." Xia Xiqing brought the piece of paper to Zhou Ziheng, and Zhou Ziheng entered the path according to the line, and sure enough, he found an executable file named rose in a deep hidden folder. , after execution, three numbers are printed directly on the black screen.

[163482089474]

"Technology is the primary productive force." Xia Xiqing sighed sincerely, and then copied the remaining two four-leaf rose numbers into the blank space of the title.

Zhou Ziheng leaned back on the chair, his too long legs were too long to hold back, so he could only spread them to the two sides of the round table, with his hands in the pockets of his jacket, he focused on sorting out the current clues with brows.

Zhou Ziheng's logic is very clear, "We have now got two four-digit numbers. Judging from the previous room, there is a high probability that it will be the password of something. However, we have not found any items that need to be opened with a password, indicating that there is something A thread breaks here."

Zhou Ziheng's voice was deep and beautifully resonant, which reminded Xia Xiqing of the bells of Giotto's Bell Tower in Florence and the sunset of the Cathedral of Santa Maria del Fiore.

When he passed there with the drawing board on his back, the heavy bell struck his heart valve one after another, and his whole body was numb, as if he had been electrified.

"Um?"

The other party asked a question, and Xia Xiqing recovered from the sunset in Florence. Seeing Zhou Ziheng looking at him suspiciously, he asked again, "What do you think?"

Xia Xiqing nodded at this point. Although he didn't hear what Zhou Ziheng said before, he could probably guess that it was related to the current chain of clues, "That's right, our goal now is to find the missing one." He flipped through the clues that Shang Sirui had found before, and there was only one palm-sized memo that hadn't been checked, so he roughly flipped through it.

Shang Sirui, who kept looking around, said next to him: "I just found this next to my pillow. I searched for it for a long time but I didn't find anything useful. I just remembered some miscellaneous things. What's the number?" Go to the meeting, pick up the children. There are words written by children on this memo, which is a mess."

Words written by children?

Xia Xiqing noticed something was wrong, so he flipped through it again. Sure enough, in this memo was not only the handwriting of the owner of the room, but also the handwriting of the four-leaf rose math problem, but the content was nothing more than some words to his father. Going out on a trip by yourself, and some have ideas such as attending parent-teacher meetings.

I checked it again, but there is still no information worth pondering.

What is wrong?

Xia Xiqing put down the memo, put his hand on his forehead and bowed his head to think. Zhou Ziheng reached out and took the memo, flipped through it, and suddenly said, "Is there a page missing here?"

"Really?" Xia Xiqing looked up, but he really didn't notice. Zhou Ziheng opened a certain page of the memo, and sure enough, there was a jagged edge left after it was torn.

"So in the wastebasket just now..." Xia Xiqing suddenly remembered that there was indeed a piece of waste paper the same size as the memo, which was written by the teenager!

He walked over, knelt down on one knee and found the piece of paper. Although Shang Sirui hadn't figured out the situation yet, he followed suit and moved to Xia Xiqing's side to read out the information written on the torn memorandum.

"Dad, the pen you gave me fell under the bed, but I can't reach it, can you help me find it?"

pen?

Zhou Ziheng walked over and knelt on the ground to check the bottom of the bed, but the bed seemed to be solid, with wooden cabinets on all sides, and there was no space under the bed at all.

Xia Xiqing knocked on the wooden surface.

Not solid.

The moment he stood up, he saw a camera installed at the foot of the bed, and he was even more sure of what he was thinking, "We have to move this bed away."

"Really?" Shang Sirui was a little skeptical, "No, I don't think so, is there any other clues? A pen feels like... and there are so many information in the memo..."

Zhou Ziheng shook his head and asked, "Is this piece of paper in the memo?"

Shang Sirui didn't react, "No, isn't this torn off?"

Zhou Ziheng nodded, "So... if you were the owner of this memo, why would you tear up a page of it?"

After listening to his question, Shang Sirui crossed his arms and thought for a while, "If you tear it up... there are many possibilities, such as it is useless, ah, but I feel that the whole memo is useless...For example, I don't want to be seen by others... ?" He suddenly got what Zhou Ziheng meant, and snapped his fingers to point at him, "He doesn't want to be seen!"

Zhou Ziheng smiled with an expression of you finally enlightened.

Xia Xiqing lifted one side of the bed by himself, and was about to ask for help, but found that the bed was surprisingly light, and he could lift half of it by himself.

It really is a prop...

The three moved the bed away without much effort. There were no marbles under the bed, only a box. To be precise, it is a safe with two rows of password columns, and each column needs to place four numbers.

On the box was a rose, with four tiny leaves remaining on the branch.

"Wow, I feel like I was accidentally covered by two kings." Shang Sirui picked up the box excitedly, and entered the password according to the answer calculated by the computer before. There were two clicks, and the safe opened. up.

Xia Xiqing smiled helplessly. Could it be that Bronze entered the king's game by mistake?

Zhou Ziheng was looking at him with this smile, he really doted on Shang Sirui, he couldn't really fall in love with Sirui.

Complete misunderstanding.

"The key!" Shang Sirui was overly excited, and took out the key at once, not caring about anything else, "I can finally get out of this room."

Xia Xiqing found that there was still a document bag in the box. He opened the document bag, and inside was a power of attorney for property transfer. His expression turned cold, and he put the file bag aside.

Zhou Ziheng leaned against the wall with his chest folded, observing the expression on Xia Xiqing's face, which was his favorite thing to do as an actor. He felt strange, didn't Xia Xiqing hide his expression just now, he was obviously such a cautious person.

"Is there anything else inside?" Zhou Ziheng asked.

Actually there are. Xia Xiqing checked the password box, and there was an empty shell of medical records inside. "It seems to be stuck in the box." He tried hard but couldn't get it off, so he had to give up, "It's just an empty shell, there is no medical record in it, and there is no name. and age."

Shang Sirui glanced puzzledly, not interested too much, for him, walking out of this room is equivalent to completing the task, he took the key and inserted it directly into the lock on his own door, "The key is right, you can Turn!"

"Be careful." Zhou Ziheng said, "It doesn't matter whether there is an enemy or a friend outside the door."

Xia Xiqing smiled lightly, glanced lazily at Zhou Ziheng, and the two looked at each other again.

Not necessarily inside the door, let alone outside the door.

The author has something to say: popular science: [number of four-leaf roses]

This number with a nice name is actually a "self-power number". As the name suggests, self-power means that the nth power of each digit of this n-digit number (ones, tens...) adds up to the number itself .

For example, when n=3 (that is, a three-digit self-exponentiation), 1x1x15x5x53x3x3=153, this 153 is a three-digit self-exponentiation. But, the name self-exponentiation sounds...too mathematical, so it has some cute aliases, the most famous of which is the three-digit self-exponentiation number-the daffodil number.

This is very interesting, and you may wonder why you have to choose daffodils when there are so many kinds of flowers? This starts from an ancient Greek mythology. The river **** and the fairy gave birth to a beautiful boy Narcissus. All the fairies will fall in love with him, and the most beautiful one among them is because of his tragic fate. In order to punish him, the moon **** punished him. He casts a curse that makes him fall in love only with himself. So one day he came to the river and saw his own reflection, and the curse came true. He died by the river, which was full of daffodils.

So daffodils represent narcissism. Three-digit exponents are also called daffodil numbers.
