Squinting his small eyes, he habitually smiled at the corners of his mouth: "The third master is also safe." After finishing speaking, he dusted off his robe, stretched out his long arm, and lifted the heavy brocade curtain: "Please come into the house to talk." ”

Chen Ying nodded and stepped into the room.

The furnishings in the house are simple and elegant, several chairs and stools are all fine rosewood, and there is a bookshelf standing next to the wall, on which are the common books on the market, and the fragrance of ink seems to be invigorating. There are several delicate fruit plates on the table, a red clay stove is set up in the corner, and the water in the pot is steaming hot, warm.

Chen Ying took off her big wool shawl and handed it to Luo's mother to collect, then took out the record that had been prepared long ago from her sleeve and gently put it on the case: "This is the detective record of the Gu Dafu case, please keep it away." ”

Pei Shu picked it up in his hand, sat down opposite her, unfolded the thin booklet and flipped through two pages casually, and said with a smile: "The third master remembers it in detail." ”

Chen Ying heard his teasing, but he didn't reply sarcastically, and said with a solemn face: "This is my agreement with Your Majesty, so naturally I can't violate it." ”

As soon as the word "Your Majesty" came out, Pei Shu's expression froze for a moment, and then he pouted: "This official knows, the third master is ordered to investigate the case." Gold Medal Detective. ”

The corners of Chen Ying's mouth moved, and her signature smile immediately appeared, and she replied with a ready-made humble word: "Little Hou Ye has won the award." ”

The corners of Pei Shu's mouth twitched even more, and he didn't speak.

Chen Ying was also speechless for a while.

So, the room fell silent.

Fortunately, this silence is not embarrassing, the charcoal fire sometimes bursts out with a "peeling", and the wind beats the curtain, but it does not feel dead silence.

After being silent for a while, Chen Ying opened her mouth first: "But I don't know why the little marquis invited me here?" ”

Pei Shu seemed to be in a trance, and at this moment, he was awakened by her voice, so he leaned forward, and while putting the record into his sleeve, he said in a deep voice: "I have something to say, it's about that ghost crying mountain." ”

didn't fight with Chen Ying much, and told him directly, but his words were a little vague, but Chen Ying understood that the Ghost Crying Ridge here should refer to King Kang's Farewell Village.

"What's wrong? Something wrong with that place? She asked in a relaxed tone as she picked a crisp from the fruit plate and put it in her mouth.

Pei Shu nodded, and his face instantly turned cold: "Yes." Somewhere in Nabezhuang, our men found a fragment. ”

"Oh?" Chen Ying's eyebrows moved, and a bright light flashed in his watery eyes for a moment: "Isn't there anything special about this fragment?" ”

Pei Shu didn't speak, only took out a page of paper from his arms, pressed it with two fingers, and slowly pushed it to Chen Ying.

Chen Ying's attention had been attracted by the paper at this time, and she wiped her fingers with the cloth towel, then took the page and opened it to take a closer look.

It was supposed to be an improvised transcription, not an original manuscript, and the paper and ink were new, and the handwriting on the paper was stiff, and the skimming was like a sword.

Chen Ying glanced up at Pei Shu: "Is this a transcription by the little marquis himself?" ”

"Yes." Pei Shu replied in a deep voice, his eyebrows cold.

Chen Ying smiled, looked down again, but saw four sets of numbers written on the paper:

One hundred twenty-nine, five;

xxxvii, sixty-seven;

One hundred and one, eighty-six;

XII, III.

The two numbers are arranged in a group in an orderly manner, and at a glance, there does not seem to be any direct causal relationship between numbers and between groups.

Chen Ying's eyes were fixed on those numbers for a long time, his eyes were shining, he didn't speak, Pei Shu didn't say a word, and in the room, except for the sound of water, almost a needle drop could be heard.

Luo's mother and Lang Tingyu all withdrew at some point, and there was an inexplicable tense atmosphere in this room with only two people at the moment.

After staring at those numbers for a long time, Chen Ying's eyebrows raised and he let out a light "huh".

"How?" Pei Shu had been carefully observing her reaction, and when he saw this at this moment, he immediately asked out loud: "Did you see some pattern?" ”

"Regularity?" Chen Ying asked rhetorically, raised his head, and looked at him with a strange gaze: "Is there a law between these four sets of numbers?" ”

"Doesn't it exist?" Pei Shu's expression was even stranger than hers, and he looked back at her in surprise.

Chen Ying didn't say anything for a while, only closed her eyes slightly, and thought carefully about the possible rules in these four groups of eight numbers in her mind, and then opened her eyes and said in an affirmative tone: "There should be no mathematical rules between these four groups of numbers." And if I'm not mistaken, these four sets of numbers should correspond to one word each. ”

Pei Shu's eyes lit up all of a sudden, almost like two tiny light bulbs, and asked, "How do you say this?" ”

When he said this, he was really a little excited.

He knew that it was right to find the third girl for these things, and several subordinates on his side were puzzled, and the matter was secret, so they couldn't be investigated in a big way, and they were really distressed for a long time, until His Royal Highness the Crown Prince proposed to ask Chen Ying for help.

In fact, Pei Shu had already thought of Chen Ying, but it was a little difficult to speak, after all, there is a difference between men and women, and now that the prince has proposed it first, he responded immediately.

"It's supposed to be a password." Chen Ying said, not minding whether Pei Shu would not understand this novel word.

Pei Shu really understood.

Even though it was the first time he had heard the word, it wasn't too difficult to take it literally.

"What is the meaning of this so-called password?" He asked, with a rare eagerness on his face.

Chen Ying stretched out her hand and pointed to the page, and said calmly: "These four groups of numbers, each group has two, according to my understanding, the first number should correspond to the page number on a certain book, and the latter number is the number of words counted in a certain order by the page number." ”

She was afraid that Pei Shu would not understand, so she got up and took out a book from the shelf, sat back in the chair, turned a page at random, pointed to the page number and said, "Little Marquis, please look, the page I am turning now is the ninth page." As she spoke, she wrote a false "nine" on the case with a reference pen.

Then, she pointed to a random word on page 9 and said, "This is the twelfth word on page 9 from front to bottom." ”

As she spoke, she wrote down the number "twelve" again, and continued: "You see, in this way, I have a set of numbers, one is nine, and one is twelve. ”

Pei Shu had already understood a little, but he still frowned and groaned, a little incredulous.

In his opinion, these four sets of numbers should have a more difficult and complex solution, but Chen Ying's solution was extremely easy, which made him feel like he was stepping on the empty foot.
