"That's it? So easy? Pei Shu looked at Chen Ying, the expression on his face was between stunned and confused.

Chen Ying nodded, her face did not change in the slightest: "It should be like this, it's that simple." After thinking about it, he added: "I remember that there was a secret order called 'character test' in the former Korean army, and these four sets of numbers are almost the same as the meaning of 'word test'. It's just that the 'word test' is based on the four crosses of the old poem that does not repeat the words, and each word represents a directive. The password here is based on a designated book, and each set of numbers represents a word. ”

She stretched out her finger and pointed to the words corresponding to the two sets of numbers, and said: "For example, the group of numbers I listed, based on the book in my hand and the conditions I gave, correspond to the word 'and'. ”

Pei Shu already understood her words, pondered for a moment, and nodded slightly: "The method of word verification is indeed available in the army, but it is rarely used now." ”

He has been in the army for many years, so he naturally knows this kind of code language in the previous dynasty, but now the Great Chu Dynasty has changed to other forms of code language, but this "word test" is rarely used.

"I see." He said again, the groan on his face gradually faded, and he was a little convinced by Chen Ying's explanation.

If Chen Ying put forward this idea out of whimsy, although he would believe it, he would always have doubts, but the "word test" is a good example, which makes his feelings more appropriate.

"In this way, these four sets of numbers do seem to be derived from the 'word test'." He finally said, leaning back and looking much more relaxed.

Chen Ying glanced at him with a smile and said calmly: "When I first saw these four sets of numbers, I really wanted to find out the rules from them, but this method didn't work, so I thought of 'word test'." ”

Mr. Detective is proficient in mathematics, and Chen Ying herself is a top student, and her skills in finding patterns between numbers are far ahead of her time.

And if even she can't find a pattern, it means that these four sets of numbers have no pattern at all, but have other meanings, so she quickly thought of this uncomplicated modern password.

"Naturally, it's likely that my guess was wrong too." Chen Ying said again.

She didn't dare to be too big, after all, this was still just her speculation, and it could only be said that it provided Pei Shu with an idea, not a conclusion. So at this time, he continued: "Since the little marquis has asked me here, I naturally want to say what I think. I still have that point of view, when there is no way, all seemingly unbelievable methods can be tried. ”

"That's true." Pei Shu agreed, and couldn't help but think of Chen Ying digging flowers and plants in the maze.

At that time, who would have thought that this Chen San girl would really be able to "dig through" the maze with that weird "plant distribution method"?

Thinking of this, Pei Shu felt more and more confident in his heart, and a slightly evil smile appeared on his face, and said teasingly: "The third master doesn't have to be too humble, the first line of heaven rejects the enemy, the ghost crying ridge explores the way, plus the murder of the old lady He, this case shows that whatever the third master thinks, it must be reasonable." ”

This sounds like a joke, but Pei Shu thinks more or less so in his heart.

Chen Ying's previous performance was really too good, if she was a man, Pei Shu would have sent someone to Pei Jiajun as a military advisor a long time ago, and it would never be like this, if you want to ask something, you have to find a passable reason.

"The little marquis is too famous." Chen Ying bent her eyes and smiled, feeling very comfortable.

The so-called cooperation must always be built on the basis of mutual trust and mutual benefit. Now, her partnership with Pei Shu should have entered a virtuous circle.

For her, this is a huge step forward.

Thinking about it, Chen Ying got up and came to the red clay stove, wanting to pick up the beam pot and make tea.

It's just that the crooked beam was burned hot by the fire, and it was really hot, and as soon as Chen Ying's hand touched it, it was immediately scalded and retracted, and then she turned her eyes around, thinking about finding a handkerchief to cushion her hands.

Who would have thought, as soon as she moved here, there was a sudden darkness beside her, and a big hand with distinct bones then poked into her sight, and easily lifted the beam pot.

Chen Ying was surprised, and saw Pei Shu carrying the kettle to the side of the case like a child, poured some hot water into the Ruyao bean green teapot, and said, "This pot is very hot, I'll come." ”

As he spoke, he filled the teapot, put the kettle on the stove again, and then picked up the teapot and poured two teas.

Chen Yingwei was a little stunned to see him doing all this, and always felt that his behavior at the moment was really very different from usual.

"Drink it, the tea is good." Pei Shu sat down and said this, as if he didn't realize what he had just done.

But Chen Ying noticed his abnormality.

The little marquis actually poured tea for himself?!

Chen Ying remembered very well that when she was in the Siyi Hall, she poured tea for him, but not only did he not drink it, but he also washed a cup again.

What's wrong with him today? Transsexualized?

With these questions in his heart, Chen Ying didn't show it on his face, thanked him, and sat back where he was.

The code paper was still on the table, and after muttering for a while, Chen Ying continued the topic of Fang Cai: "Generally speaking, the book corresponding to this password should not be the kind that is not very out of the way. If the little marquis has time, he might as well find some books on the market to try, and maybe he can find these four words. ”

She paused for a moment at this point, picked up the teacup, and said: "If these four groups of numbers are not east and west, but are arranged coherently, then the four words found should be able to make up a whole sentence." ”

Pei Shu didn't hide it from her, and said bluntly: "That fragment is only the size of a palm, just write these four sets of numbers, I think, they should be continuous." ”

"That's fine." Chen Ying took a sip of tea and smiled pleasantly.

She did Pei Shu another favor.

Counting the wood carvings on the corpse of the nameless woman and the labyrinth, Pei Shu owes her a favor, which should not be less.

Does that mean that the thing she wants to do can be mentioned at this moment?

Thinking like this, Chen Ying slowly put down the teacup and stared at Pei Shu, with a very different emotion in her clean eyes.

Pei Shu immediately sensed it, raised his head to look at her, raised his eyebrows, and asked, "Chen Sanye is looking at this official like this, is there something wrong?" ”

"Yes, I have something I want to ask the little marquis for help." Chen Ying's expression became solemn, and as she spoke, she took out a sachet from her sleeve.
