"What's wrong?"

"What would you do if you wanted to play a game and only had a log to bury clues?" As if he had suddenly thought of something, Yang Wenbin turned the log over and looked at it upside down.

"What do you mean...... Is there a hidden message hidden in this diary? Yan Junli immediately sat up straight.

"The clown said, look carefully with your eyes." Yang Wenbin nodded and put the diary on the table, "Let's try them one by one." ”

Then Yang Wenbin and Yan Junli began to torture the diary in all kinds of absurd ways, at first it was useless to douse it with water, roast it with fire, and put it in a dark place or exposed place. Yang Wenbin even felt that his idea was a little ridiculous.

"I don't think we'd better try it, how could the clown hide information in such a ridiculous way." Yang Wenbin threw the diary on the table and sighed, "Only elementary school students get these childish things......

"But we're not done yet." Li Hong suggested, "Isn't there anything else, the most classic way to hide information, is to use ultraviolet irradiation?" ”

"Do you really think the Joker would use such a simple method to hide information?"

"Gee, but it's always okay to try."

In the end, Yang Wenbin chose to follow Li Hong's advice, and pulled out an old ultraviolet lamp from the warehouse, illuminating the diary in the dim light. I never thought that such a photo really revealed the hidden text.

"I didn't expect there to be words!"

"Look! I'll just say it! Li Hong said triumphantly.

"You wait...... There are words, but this word seems to be a bit too much, right? Yang Wenbin brought the ultraviolet lamp close to the diary, and the three of them soon noticed that the blank pages at the back of the diary were almost all glowing Chinese characters, and the entire paper was stuffed to the brim.

"Well, it's almost good, laughing at who the cat ......," Li Hong frowned and read out the hidden words, "What the hell is this?" I can't read it at all.,Isn't this gibberish? ”

Yang Wenbin flipped through the diary in a "whoosh", and the so-called hidden words from beginning to end were all meaningless gibberish.

"What does this mean? Is this guy laughing at us? Yan Junli's tone was on fire.

Yang Wenbin turned off the ultraviolet light with a "snap", his face was gloomy, "Yes, I think this is laughing at us." Let's think differently. ”

However, even if he changes countless ideas, Yang Wenbin has no problem with this book. He thought of countless ways to separate the words in the journal, and then to separate the hidden words, and applied many mathematical formulas—but no matter what method he used, the journal was as unresponsive as if it were mocking him. On the other hand, although Yan Junli launched a carpet search for Tao Mingming, it was still fruitless.

"We don't even know if this kid's name is Tao Mingming." Yan Junli sat down in a chair in frustration, "We investigated his first few victims and asked the families of those victims. Some people say that his name is Tao Tianze, some people say that his name is Tao Yongshou, and his identity is also different, and there is no way to find out. ”

"Good evening, boys, how's work going?"

Several people looked towards the door, where Poppy was standing in a long sweater and black high heels.

"You? How did you get in? ”

"Uh, I walked in?" Poppy laughed and walked into Yan Junli's office, "Okay, I'll confess. I just gave the doorman my phone number. ”

"I'm going to fire that doorman......" Yan Junli muttered.

"What are you doing here?" Yang Wenbin remained silent, "I thought you were going to disappear and stop meddling." ”

"Anyway, this is a clown-related case, and to be honest, I didn't snatch the case from you." Poppy shrugged, "I handed over this case to a few of you because I trusted you, but I didn't expect that it had been so long, and you still hadn't made any progress." ”

"You're so ashamed to say that." Yan Junli's fire just now hasn't gone down yet, and now he is even more upset by the poppy, "It seems that every time we investigate a case, you suddenly come out of nowhere and make a stumbling block!" Now you're embarrassed to complain that our investigation is too slow? ”

Poppy didn't get angry or refute when he heard this, he just smiled slightly and picked up the diary on the table, "If I'm not mistaken, you probably put a lot of energy into researching how to solve the puzzles in this diary, right?" ”

"What else else can we do? The diary is the only clue left by the Joker. What's more, there is no key point to be found anywhere else. Yang Wenbin said.

"Doctor Yang, I have to say that you are a very smart person, but sometimes people are smart and mistaken by smart. Have you ever thought that the diary thing may be your overthinking? Poppy smiled slightly.

"When illuminated with a UV lamp, the blank pages at the back do show hidden text. It's just that those words are like garbled characters, and there is no pattern at all. Yang Wenbin frowned, "There must be some way to crack them—"

But have you ever thought that these irregular words may not be passwords in themselves? What about tools to crack other passwords? Poppy took the diary and gently tapped it on Yang Wenbin's head, "You've always checked the dictionary, right?" We've all looked up the dictionary. When we encounter a word we don't know, we will look it up from the dictionary through the pinyin or stroke of the word, and finally find the word, which is the truth we want to find in the end. ”

Yang Wenbin suddenly understood, as if he was drenched on the head by a basin of cold water, "You, you mean!" This book is not a puzzle, but a dictionary? ”

Poppy nodded, spreading the diary on the table.

"Do you remember those weird murals in Tao Mingming's house?"

Yang Wenbin nodded, and Yan Junli opened the desk drawer, took out a dozen photos and spread them on the table.

"The photos of Tao Mingming's home are all here."

One by one, the poppy pulled through the pictures, picked out all the murals on the walls, and lined them up.

"If you look at these murals, do you think these patterns are a little close to the numbers?" The poppies showed them one by one, "I arranged them in order from the outside to the inside." You see, the wall closest to the door is painted with a snake, and the direction and angle of the snake does not look like the number '5'? Then look at the one in the back, the pregnant woman who spits flames in her mouth, the flames in her mouth and her belly are connected, is it the number '6'? ”
