The tall and thin middle-aged man glanced at Yuan Fen and said cheerfully: "Okay, then let you try." ”

In his eyes, he became more and more satisfied with this young man who did not give up easily when he encountered things.

It's a pity that it's two years old.

He shook his head, and saw Su Beimo holding the iron box, studying and fiddling.

Su Bei understands that the possibility of unlocking the yin and yang lock is extremely low, and now he can only be a dead horse as a live horse doctor.

He observed for a moment, but found nothing.

So, he took out his mobile phone, opened his life file with the word "Rong", and observed the changes in the expression of the iron box like observing the crimson certificate.

However, there is no more to gain.

The only thing that is certain is that this iron box is indeed made with a yin-yang lock.

In addition, it is also clear in the archives that the material of this box is special, and it is difficult to open it with brute force, and even if it is forcibly broken, it will damage the contents inside.

This made northern Jiangsu have to be cautious.

"Yin and Yang lock, Yin and Yang lock, the focus is on the word Yin and Yang. ”

He whispered, thinking quickly.

Since mastering the knowledge of "metaphysics", northern Jiangsu has a deeper understanding of yin and yang.

In the Suzhou Cultural and Sports Center, he understood and applied the relevant concepts.

The line in the Book of Changes is divided into two kinds: yin and yang, called "-" for yang and "--" for yin.

These two runes are also like men and women.

But what does this have to do with the lock in front of you?

Su Bei looked at the iron box in his hand repeatedly, and suddenly thought that in modern science, the origin of binary is because of the yin and yang science of Xia.

In the 18th century, Leibniz, a master of mathematical philosophy, published the article "On the Philosophy of Xiaguo", and discovered the secret of binary from the yin and yang gossip.

Later, this became the basic unit of the computer system, and the data was stored in binary form at the bottom of the computer.

The binary system in this is to use "0" and "1" to represent everything and store everything.

Binary, on the other hand, can be interoperable with decimal and hexadecimal.

"Could it be that Zheng Peiyuan's key is hidden in a certain string of numbers he left behind?"

Su Bei thought deeper from this.

"Perhaps, finding this string of numbers and converting them into binary is the key to the yin and yang lock!"

The more he thought about it, the more he felt that it was possible, and began to recall everything related to Zheng Peiyuan.

The focus is on the "Archaeological Notes" he left behind.

There are a couple of suspicious things about this.

The first one, the number of the Fire Cloud Evil God Archaeological Team, is 6 people. And "6" is converted to binary, which is "110".

It seems too simple.

The second is that Zheng Peiyuan once recorded in his archaeological notes that through the excavation of four secret places, he found 9 beads to open the secret door under the glacier.

And "9" is converted to binary and is "1001".

There is a glimmer of possibility in this number.

The third is the date when Zheng Peiyuan returned to Nanling City and issued the newspaper, February 2, 2020.

"" Convert to binary is "".

It's relatively complicated.

If you only convert with "2020", it is "".

More likely, it seems, a little.

However, these are all speculations, and whether the yin and yang locks can be unlocked can only be practiced.

"Uncle, I have some conjectures that it may take three or five attempts. ”

Su Bei raised his head, looked at the two of them, and said.

Yuan Fen's father waved his hand and said nonchalantly: "It's okay, you can try casually." The girl and I have pressed the button many times. ”

"However, no pattern was found. ”

"And, two minutes after pressing, if you don't do it, listen to the sound, and they'll automatically recover. ”

Su Bei nodded, understanding his point.

The first thing to try is "110".

"0" is yin and "1" is yang.

Holding on to the iron box, he pressed the "yang" button twice, and then the "yin" button.

The sound of a machine running sounded inside.

However, it still couldn't be opened, and after a few moments, the bracket inside rang again, and it returned to its original state.

Su Bei was a little disappointed in his heart and had a bad start.

Then, he tried "1001" again, and pressed the yin and yang buttons on the iron box in turn.

Again, however, it failed.

Su Bei's forehead couldn't help but sweat.

His thinking may not be wrong, but he obviously did not understand Zheng Peiyuan's true intentions.

Now, it can only continue.

When the yin-yang lock returned to its original state for the second time, he operated according to the ideas of "" and "2020".

There was a noise in the iron box, but it still couldn't be opened, and it was back to its original state in a few moments.

"Subei, if you can't open it, forget it. ”

Yuan Fen saw that his brows were tightly knit, and he couldn't help but comfort, "A repair shop is not worth much, if not, let's buy another set." ”

Su Bei looked at her when he heard this, and when he heard this, he planned to make himself struggle for less than 20 years?

No, my generation is a martial artist, how can I eat soft rice!

No, we haven't reached that level yet!

I almost got hooked up.

He was interrupted by this, his train of thought was broken, and he remembered it again. However, after all, this is Yuan Fen's home, and the things are other people's things, and they can't be consumed for a long time.

"Will it ...... Is there another possibility?"

Su Bei was anxious, and suddenly thought of an immature idea.

Since Zheng Peiyuan knows the keyboard, will he also know about the existence of the Dao server?

If so, did he log in?

He...... Know the address, username, and password?

Subei's attention fell on the "address", and the login address of the Dao server was:

telnet..............................

"telnet" represents the connection instruction, and the next 30 dots represent the destination IP.

The normal IP address format is something like "192.168.0.1".

But the road server, however, is a maverick and is a series of 30 ".".

An unrealistic idea surged in Subei's heart, that is, to convert "30" into binary, which is "".

He flipped through the iron box.

Press the knob for "yang" four times in a row, and then press the knob for "yin".

"Smack. ”

A crisp unusual voice sounded.

Su Bei was overjoyed, he was really right! He really opened the iron box!

"Hey, you...... You succeeded?!"

The two people next to him exclaimed at the same time, "How is this possible?

Subei was silent.

It's really possible that I'm shit lucky.

Although the iron box was opened, more doubts rose in his heart.

"Could it be that Zheng Peiyuan's real purpose in leaving this iron box is not to keep the documents, but to tell the latecomers the address of the Dao server?"

He pushed open the box, and inside was a roll of yellowed paper, old.

Nineteen years have passed in a hurry.

Through the paper, he seemed to see the busy figure of nineteen years ago, what people were doing, what they cared about, and what were they expecting?

Spread out the file.

Sure enough, it was the words "bequeath".

The handwriting looks old and simple, but one stroke at a time, exactly the same as in the "Archaeological Notes".

This is indeed Zheng Peiyuan's handwritten document.

"Subei, I didn't expect that the inheritors of my father and Old Man Zheng are really you. ”

The tall and thin middle-aged man smiled, and his body was light, as if he had let go of a certain burden, but he had a heart.

"Thank you, uncle, this bequest document ......"

Su Bei sighed gratefully, grabbed the yellowed paper, and looked at him embarrassedly.

How could Yuan Fen's father not understand his thoughts, and said heartily: "Since you really opened the box, then it stands to reason that it should belong to you." ”

"Don't worry, take it. ”

The tall and thin middle-aged man waved his hand, without nostalgia.

Su Bei's heart was a little moved, this middle-aged man who had met with a plain taste, was rare and enlightened and kind.

He gripped the paper tightly and thanked him again.

At this point, the dust has settled.

Yuan Fen's father was in high spirits and did not let him leave immediately, but pulled him to sit down and drink tea.

The three of them chatted for a while, and they were very happy.

Su Bei accompanied him to drink tea, laugh and talk, but he kept this kindness in his heart.

"By the way, after chatting for so long, I still don't know what Yuan Fen's father's name is?"

He thought suddenly.

However, it is not convenient to ask this question directly.

He took a gap, lit up his phone, switched to the "Rong" word directory, and finally found the other party's name.

It turned out that his name was Yuan Zhoulu.

"That's a good name. ”

Su Bei smiled secretly, and seeing that it was very late, he finally put forward the idea of saying goodbye.

"Subei, you and my Yuan Fen are classmates, they are of the same age, and you have to move around more in the future. ”

Yuan Zhoulu took his hand and said.

In this short period of time, Su Bei's humble and polite and knowledgeable image made him like it very much.

While sending Su Bei out, he advised: "If you young people think I'm nagging, I can also give you more time." ”

"In short, you are welcome to come to our house often in the future, and you will communicate more in school. ”

Su Bei was a little overwhelmed by his enthusiasm, so he had to laugh awkwardly and agree.

At the end, when he walked out of the door, he couldn't help but remind him, "Uncle, Tieguanyin contains a lot of tannic acid, so it's better to give Yuan Fen less to drink." ”

Then he turned and left.

Yuan Zhoulu watched him go downstairs before closing the door and pondering the last sentence.

"Well, no, this guy understands tea!"

He pondered for a moment, and suddenly it dawned on him.

The tannic acid in this Tieguanyin can be combined with the iron in the human body to form an insoluble conjugate, so that the body does not get enough iron source.

And Yuan Fen is a girl, once she drinks too much, it can easily lead to iron deficiency anemia.

Hey, as a father, no outsider has thought it through.

Su Bei walked on the way back, but his mood was a little heavy, since Zheng Peiyuan knew the address of the Dao server, had he logged in?

If so, has he changed anything?

If he hasn't logged in, then what does the binary meaning of this string of "30" mean?

Where did he get this string of binary numbers, or was it really a coincidence?

And what if it's not a coincidence?

Tell him who the person who will be this string of numbers, and whether this person will welcome... Log in to the aisle server?

Everything is foggy.
