Gate of Mensa

The next day, Su Yuyan got up early, ready to go to work after breakfast, when suddenly the doorbell rang, Su Yuyan opened the door, it was a courier, Su Yuyan took it in after signing for it, it was his name.

He didn't remember buying anything, maybe it was bought by Chen Mo with his name written on it, so he simply opened it, opened the box and saw that there was a letter inside, on the envelope it was written that Su Yuyan received it, and it was stapled with a stapler, he opened it Inside the open envelope is a piece of paper, on which is a complex figure, which is similar to the Sudoku played by Chen Mo, but it is all Chinese characters and not Sudoku. Who sent it to him, and what does it mean?

No one would be bored enough to play with him. There was something strange about this letter. Su Yuyan went to the room and walked up to Chen Mo. The child was tired and fell asleep yesterday. Su Yuyan was in a hurry to go to work and could only wake him up first.

Su Yuyan kissed Chen Mo's forehead a few times, "Baby, wake up, baby."

Chen Mo rubbed Su Yuyan's face with his hands, "Brother Yan, I'm sleepy, let me sleep again."

"Honey, do me a favor. I'm in a hurry to go to work but I think this letter must be weird. Please read it for me." Su Yuyan continued to wake Chen Mo up.

Chen Mo's eyes were sleepy, "What letter?"

Su Yuyan handed the letter to Chen Mo, "Look, someone delivered a courier just now, and they didn't call the sender. There was only this piece of paper inside, and the envelope was still stapled."

Chen Mo rubbed his eyes and looked carefully at the words on the paper, and suddenly became sober. He looked at the graphics and words on the paper seriously, "Who will send you this?"

"What is this?" Su Yuyan was curious.

"This is Sudoku. Generally, our competitions only appear in the puzzle group. There are more restrictions and more difficult solutions, but we only solve numbers, but this is all words, but they are all arranged according to the logic of Sudoku. This is The compiled Sudoku game, the questioner is definitely a master, and his level is not inferior to mine." Chen Mo looked at it calmly, "You bring a pen and paper, and I will do the math."

"You are already a world champion. Is there anyone better than you? The point is that I don't understand. Why does he give me Sudoku?" Su Yuyan was even more puzzled.

Chen Mo looked at Su Yuyan, "What case are you investigating recently?"

Su Yuyan and Chen Mo looked at each other, "The drug dealer was murdered in an unfinished building."

Chen Mo glanced at the text Sudoku again, "It is estimated that your investigation of the case has touched someone's interests or safety. They are writing you a warning letter, but the other party is not an ordinary hooligan, but a high IQ boss.

Of course he knows that you can't solve such a difficult Sudoku puzzle, but he still sends it to you, why?

Because he knows that I live with you, I will interpret it for you. He knows your whereabouts very well, and may have started to follow you.

Immediately check any corners of your home carefully to see if there is any bugging or supervisory device. When you go to the police station later, you should also carefully check the surrounding environment to see if anyone is watching your whereabouts.

From now on, we must pay special attention to safety. When going out to investigate the case, there must be more than two people and they must be equipped with guns. They cannot act alone.

I'm reviewing at home, don't worry, I won't go out, if I'm hungry, cook in the rice cooker and then heat up your dishes.Do not open the door to any stranger.I have the watch you gave me, and you can check my location at any time. If my watch is lost, my mobile phone is also bound to your mobile phone with positioning installed, and you can check my signal location. "Chen Mo was solving problems while talking.

Su Yuyan couldn't understand the drawings on the draft paper, "Mo'er, sometimes I can't believe that the little cutie lying in my arms is amazingly scary once she uses her brain. So calm and comprehensive, I almost adore you."

Chen Mo smiled, "It's normal to worship me. I'm really smart, but there are still many people who are smarter than me. The problem has been solved. These few words should be what the sender wants to bring to you."

Su Yuyan looked at the writing on the paper, "Don't meddle in your own business and take care of yourself", "Is this a warning to me?"

Chen Mo nodded, "The more nervous the other party is, the more he can prove one point. You have checked the direction. He is afraid that you will pursue it further and find out the truth, so he threatens you first and makes you afraid to quit. As long as the case cannot progress due to insufficient evidence, Then it will be left there, and it will be even more difficult to check after many years.

If I'm not wrong, you've already been targeted when you go on a business trip.I read at home every day and didn't pay attention to the surrounding environment, but I will be careful from today. You are lucky not to be ambushed in other places. It may be that the other party thinks that the time has not come yet, but as you investigate more and more clues, The more likely the murderer is exposed, the more likely he will take the risk and kill you.

Drug dealers are usually involved in gangsters. The area you investigated has not found any big drug syndicates, but it is said that the market is very wide. It can be seen that there are people who cooperate with others, most of them are people in the police force. When you investigate, you must keep it secret or set up a bait Catch big fish, but if the scope is too wide and your ability or even my dad's ability can't be overwhelmed, don't take risks, accumulate strength and fight for a long time. This kind of deep-rooted situation must figure out the way A one-hit kill or you'll be in a passive that can be dangerous.

My intuition is that this murder case is not just one murder case, he may be involved in several cases.Don't be confused, clear your mind, there must be an internal connection between them, find the main thread, and follow along to find the answer you want. "Chen Mo looked at Su Yuyan with a smile after speaking.

Su Yuyan embraced Chen Mo's small face and kissed deeply, "Oh, I haven't brushed my teeth yet."

"I don't dislike you baby, why do you think you are so smart? You don't know anything about this case, and you are really talking about it. If it were someone else, I would definitely think it was a mess, but you are more than Once, your logical thinking ability is too strong, you can push away a little mung bean-sized clue, and you can open a big hole. What!" Su Yu said foolishly.

"Don't be too happy. The fact that the sender can remind you like this today proves that he is not weak. What I can think of, the other party must also be able to think of. This is like a competition. Whoever runs faster will walk faster. You can win the game if you are stable, I still say that safety is the most important thing!" Chen Mo looked at Su Yuyan affectionately.

If it were someone else, when encountering such a situation where threatening letters were delivered to your door, your mind would definitely be confused, but Chen Mo, a child who is not in danger, first thinks about Su Yuyan's safety and his own safety, so he can rest assured to investigate the case Don't worry about yourself, you can also help him sort out his thoughts, Su Yuyan sometimes thinks, how can he not love such a good and considerate boy!

Su Yuyan checked the house carefully, and was ready to leave after confirming that it was safe, "Then I'm leaving, you must be careful yourself, call me if you need something, breakfast is in the pot." Su Yuyan put away the letter, and kissed Chen Mo Walk out of the room at once.

Chen Mo looked out the window, no one disturbed his dream on such a fine day, he went to the living room and fastened the door bolt, covered himself with a quilt and fell asleep again.

In the police station, Chen Guojun was drinking tea and almost choked on Su Yuyan's words, "What? You said someone wrote you a threatening letter?"
