After a few days of calming down, Gu Lili also returned to the archaeology department to continue his classes, and Zhou Xiaolong also started his university life step by step.

However, just this evening, Zhou Xiaolong was finishing eating in the cafeteria, and Uncle Nine called again for this trouble.

"Uncle Nine, why did you call me again?!! Zhou Xiaolong said impatiently.

"Oh, Xiaolong, don't be so outside, how can I say that my uncle and you are also old acquaintances, are we also a family?"

"Uh, Uncle Jiu, what's the matter with you, I'll hang up the phone if it's okay!"

"Wait, wait, there's a little thing I want to tell you about......"

"Okay, say it!" Zhou Xiaolong asked with a frown.

"Guess who is the wife of that deceased man we found in the mountains?!"

"How do I know who his wife is?!!"

"Li Erni......" Uncle Nine said in a deliberately elongated voice.

After Uncle Nine said the name, he deliberately paused, in order to give Zhou Xiaolong time to reminisce.

However, Zhou Xiaolong thought about it for a long time, but he didn't come up with anything, and he didn't know a woman named Li Erni.

"I don't know ......," Zhou Xiaolong replied affirmatively.

"Okay, let me remind you," Uncle Jiu changed his words, "Xiaolong, the night I drove with you to the mountains to find the location of the corpse, listening to the radio in the car, there was a message, do you still have an impression?" ”

Zhou Xiaolong recalled that it seemed that in the car at the time, the radio did broadcast a news, saying that a woman had stolen money from relatives at home, and the radio also told listeners to be wary of pyramid schemes, as if there was such a news.

"That's right, that woman is Li Erni." Uncle Nine said.

"Oh, I really don't remember this, Uncle Jiu, you have a really good memory, you deserve to be the old man at the yamen, admire, admire, what, nothing, I'll hang up the phone......"

"Don't, I'm not finished yet," Uncle Jiu is really thick-skinned, "The reason why Li Erni did those things is because she received a letter from her husband a month ago, that is, the deceased sent her, there is no address to send the letter, only the address of the recipient, I didn't expect Li Erni to open the letter and read it, the letter is written in the same way as the book of heaven, I can't read it at all, but after reading the letter, Li Erni went crazy and became a liar who stole money......"

"What is written on that letter?!" Zhou Xiaolong asked with some curiosity.

"It's not a word...... it's written on it," Uncle Nine said mysteriously and secretly.

"Is it a painting ?!! a painting?" Without waiting for Uncle Nine to finish speaking, Zhou Xiaolong interrupted him and asked.

"It's not words, it's not paintings, it's numbers, in fact, it's just two numbers, '0' and '1', and then I wrote a big sheet, and I don't know what it means."

"0 and 1, what does this mean?!" Zhou Xiaolong seemed to have been led into the pit and asked curiously.

"Xiaolong, why don't you come to my studio and help me see how about it?!"

Uncle Jiu is really too old and calculating, and when Zhou Xiaolong's curiosity was at its peak, he made his sinister request, and as a result, Zhou Xiaolong fell for it.

The book is brief, and he followed the SUV driven by Uncle Nine to Uncle Nine's studio, but this time, Zhou Xiaolong didn't see the teenager playing games.

"Uncle Nine, why is there one less person in your ghost place?!" Zhou Xiaolong asked.

"Who?!" Uncle Nine didn't react.

"What about your assistant with big thick spectacles?"

"Oh, you said kid, he's not here, he's gone to give lessons to the city police officers......"

"Class, he still teaches the police officers?!"

"Yes, Xiaolong, don't underestimate that kid, he's also an expert in one aspect......"

"Wow, sure enough, people can't look ......" Zhou Xiaolong said in his heart, what kind of expert, the expert who plays games is almost the same.

"Don't talk about those useless ones, you can take a look at this letter first!" Uncle Nine said.

As he spoke, Uncle Nine turned on a computer, and the computer desktop startled Zhou Xiaolong and Uncle Nine, it was a picture of zombies gnawing at each other.

It must have been set up by the boy with a dark heart, because this computer is the one where the kid plays games.

Uncle Nine clicked on a folder and brought up a picture, which was a scanned picture of the letter.

"Xiaolong, look at it, it's such a letter, it's very strange!" Uncle Nine said.

When Zhou Xiaolong saw this, he immediately felt strange, the paper of the letter was very ordinary, it was ordinary letter paper, and there were not many words, and there were about five or six lines.

But the strange thing is that there is not a single Chinese character on it, only two numbers, "0" and "1".

That's right, the content of the entire letter paper is two numbers, that is, "0" and "1" sorting, just like the cipher code in the anti-special film.

It's hard to understand, but here are some excerpts, such as this sorting:

，，00001……

"This ...... It's a password, right?! Zhou Xiaolong couldn't understand the content at all.

"At first, I thought it was a password, but I asked an expert from the technical department, and the expert said that it was not a password in the general sense, but it seemed to be a binary code......"

"What does binary mean?!" Zhou Xiaolong asked.

Of course, Zhou Xiaolong doesn't know what binary is, in fact, few ordinary people understand binary.

To explain briefly, binary is a number system widely used in computing technology, and binary data is represented by two numbers, 0 and 1.

Its base is 2, the carry rule is "every two into one", the borrowing rule is "borrow one when two", discovered by the 18th century mathematical philosophy master Leibniz, the current computer system we use, the use of basically binary system.

Anyway, Uncle Nine did what the expert said, but in fact, he didn't understand it too well.

"Xiaolong, can you see what is hidden in this?!" Uncle Nine still pinned his hopes on Zhou Xiaolong.

"I don't know, I really can't see it," Zhou Xiaolong shook his head, "But, Uncle Nine, can you tell me what this letter represents?!" ”

"The letter was signed by the deceased, that is, Li Erni's husband sent it to Li Erni, but in fact, according to the postmark of the envelope, Li Erni's husband was dead before the letter was sent...... Uncle Jiu further explained.

"In other words, this letter was sent to Li Erni by someone pretending to be Li Erni's husband?!" Zhou Xiaolong asked again.

"That's right, so, our organization believes that the person who sent the letter under the false name is likely to have something to do with the death of Li Erni's husband, and when Li Erni received the letter and read it, Li Erni was a little crazy, as if someone gave a psychological hint, stole the money from relatives, and remitted it to a bank card, but after the police investigated, the bank card was already an empty card, and all the money in it was taken away, and no information about the original card holder could be found......"

"So, this is still a fraud?!" Zhou Xiaolong couldn't help but ask.

"Yes, this kind of case should not have been handled by our organization, but I am also very curious about such a strange letter," Uncle Nine shook his head with a wry smile and continued, "Because I am a person with obsessive-compulsive disorder, if I can't figure out something, the whole person will be uncomfortable...... If, if the manipulator behind the scenes can be found from this letter, then the murderer can also be found in the death of Li Erni's husband......"
