After Feng Heng and Cao Qing officially established a cooperative relationship, the two exchanged clues in their hands and began to analyze all the clues they had. Of course, this is because there are many people and great power. Since they established a cooperative relationship, they have not had much scheming to frame them.

After all, there is a mutual utilization element between the cooperative relationship between two people. If one party is not sincere to the other party, they will be afraid of it, even if the other party does not do this, they will also have a fear element in their hearts.

Anyway, it's just deceiving oneself.

Cao Qing had two clues in his hand, one was a map and the other was a sandalwood box. Although this box should have been Feng Heng's thing, who told him to put it there without moving, but he was taken away by someone who took advantage of the fisherman's benefit, and he also fell into the chaos of the fishy smell.

Feng Heng had four clues in his hand, one was a diary, the key, some strange tools, and the note that fell out of the notebook—

“It’s on the top of your head!”

Ah, by the way, when talking about the strange tool, Feng Heng remembered that he had not read the description of it yet.

But when I saw the light red gas visible to the naked eye in the tomb next door, I was still a little scared. Then I thought, I still had to analyze the same coordinates in the notebook.

If Feng Heng was not mistaken, the clue in his hand might be the biggest clue in the first plot.

"What do you think of this?"

When Feng Heng was about to draw a number line in his mind to see what the numbers in these brackets were, he remembered Cao Qing beside him and asked first.

Cao Qing glanced at Feng Heng, smiled slightly, and did not give any detailed answers, but answered the question in an unquestionable manner.

"I'll tell you some text encryption methods."

How to encrypt text?

Why did she tell me this?

If she knew the answer, wouldn’t she just tell me?

Why do you still have to tell me these messy things in a fancy way, and the poison gas will be turned on automatically soon?

Feng Heng was a little surprised and wanted to interrupt her, but driven by curiosity, he swallowed the words on his lips.

"A long time ago, in the war years, in order not to let the enemy discover the key secrets of the files, some commanders would ask the people who wrote the files to adopt different encryption methods. You should have seen this in the history e-book."

"There are many ways to encrypt text. I studied historical facts in college. As far as I know, in this world, there are three ways to encrypt text that can be truly divided into one type."

"The first type is text conversion, which is to use a different vocabulary to represent another vocabulary that is incompatible with it, allowing them to force a special relationship on the surface.

For example, the word sun symbolizes morning, wind symbolizes weather, and thumb symbolizes good. Then if I send you an email with the sunshine thumb written on it, it can be understood as the sentence "The weather is good in the morning".

Of course, I'm just giving an example, no one will use easy-to-understand words like me to encrypt them."

Cao Qing stretched out a finger and said with a smile.

"The second type is text encoding, which is to convert a text into a garbled code from a string of numbers or letters, or a string of numbers plus letters. Generally, codes encrypted in this way will be difficult to understand. The encryption method is very cumbersome, but it is very safe.

For types like text encoding, the representatives we are familiar with are ascii codes, Moss codes, which are telegram codes. Of course, although Moss codes are not composed of alphanumeric characters, they are essentially almost the same. They are composed of dots and horizontal lines, which is considered garbled."

"The third type is the most common and easiest encryption method. The text password is to hide an important clue in one or more articles, and then use some weird-looking numbers or letters as passwords to unlock it.

The most common text code is the hidden poem made by the ancients. At first glance, it looks very charming, but if you look closely, you can combine various parts from the beginning to form a sentence, and this sentence is the theme of this poem."

Cao Qing explained to Feng Heng word by word, and suddenly she seemed to remember something.

"Oh by the way, the Su Wan in your team is in the same university and major as me. He has a special study of Tibetan poetry in college. He is a good at writing Tibetan poetry. But he has never seen him again after he went to the army. He didn't expect to meet him here."

As he spoke, Cao Qing seemed to be trapped in some kind of memory and did not continue to speak.

Feng Heng had already remembered everything she said in his heart and then understood it.

"So as you say, is the number behind this notebook the third type, the text password?"

"Well...yes, after I first saw these numbers, I already understood most of it, but now I need to confirm it."

Hearing Feng Heng’s question, Cao Qing was stunned, came to his senses, and nodded.

After taking the photos from Feng Heng's hand, a strong white light shone on it, Cao Qing rubbed his eyes.

"These numbers are indeed a bit like the coordinates on the number axis, but if this is the third type of text password, then these numbers must have a lot to do with these diaries. The key issue is to find the text in the diary."

"You can see that there is an arrow to the left behind this string of numbers, so you can roughly judge that the text should be read from right to left."

"I just counted all the diary lengths, and there were nineteen chapters in total, and there were even more paragraphs. There were eighteen coordinates in total. It can be ruled out that these coordinates were not read from each paragraph, but from the length of the chapter."

"Then the question is, the next thing is to judge whether to read it from the first paragraph or the last paragraph? This still needs to be practiced by yourself."

Cao Qing pointed to the text on the photo and looked at Feng Heng.

Feng Heng understood and took out the photos of the diary from the other side, then compared them one by one, and read them out.

To be honest, at this point, Feng Heng is already very grateful to Cao Qing for his help, and he can see so much from these numbers.

If you rely solely on yourself, you may not have any clues when you are poisoned to death.

Sure enough, cooperation is the most correct choice.

When Feng Heng was comparing, Cao Qing was not idle either. She was checking the clues Feng Heng exchanged for her.

Time was passing by bit by bit. When the last word was compared, Feng Heng suddenly realized something was wrong.

"Let's put your hand on the left, side, candlestick, table, can be closed, closed, poison, gas, installation."

“It’s on the top of your head!”
