Feiqing is none other than

After a phone call, Gu Jianyan, the chief of the police station, hurriedly came to visit with a large stack of documents.

"Uncle Gu!" Bai Yifei greeted him.

Bai Weiyi stood up from the sofa in a daze: "Why did brother Jianyan come here? Didn't you say that you don't have time this year?"

"Brother Yi, Yifei, where is the person who can decipher the code?"

Bai Weiyi scratched his belly with question marks all over his head.

"Dad, I'll explain to you later." Bai Yifei led Gu Jianyan upstairs: "It was my friend who deciphered the code, but in fact we are not sure, so don't blame him if something is wrong."

"I won't blame him. It's not smooth sailing for us to solve the case. Detours are common."

The two chatted a few words and walked to Qin Qing's room. Qin Qing stood at the door and said hello: "Hi Uncle Gu, my name is Qin Qing."

Gu Jianyan couldn't help sighing when he saw it: "This child is handsome, like a Clivia plant."

The eyes are really sharp!Bai Yifei secretly gave Gu Jianyan a thumbs up in his heart.

He always thought Qin Qing was pretty, but he couldn't think of a good metaphor.Unexpectedly, Uncle Gu would see through the appearance and see through the essence at the first sight. He is indeed an experienced police uncle.

The three of them entered the room and focused on business.

Qin Qing handed over the part of the data deciphered just now, and explained to Gu Jianyan: "The letter in the newspaper contains these English and numbers. We suspect it is the latitude and longitude. After checking with the computer just now, it is indeed located within the range of K City, so It should be right."

Gu Jianyan is very accurate at seeing people, but when it's his turn to look at numbers, he is blind.He didn't bring any technicians here at the moment, so he had to put in the deciphered results first, and then dug out the documents he brought.

"In fact, there are more than one letter. There are three letters in total, and the second one is published in the newspaper." He said while opening the sealed evidence bag in the folder: "The first letter is not the same as the last two. , the latter two letters look similar."

Qin Qing took it and looked at it carefully, and found that the first letter was full of English letters, with [-] characters per line, a total of [-] lines.The third letter is indeed similar to the second letter, and it should be encrypted in the same way.

"I can release the third letter now, and I have to study the first one." He said and picked up a pen and paper.With previous experience, I pushed faster this time, and got the answer in less than 10 minutes.

"It also seems to be a longitude and latitude. The first few numbers are basically the same, but the last number is a little different. It is estimated that it is also within the range of K City."

Gu Jianyan kept the two results as if he had found a treasure, and eagerly waited for the remaining first result.

Qin Qing didn't expect him to be so eager for results, so she could only twitch the corners of her mouth and call out, "Brother, help me."

Gu Jianyan watched the two semi-old children buried their heads in front of the password together, discussing various words that he didn't understand, and couldn't help but lamented that the waves of the Yangtze River push forward the waves of the past, and heroes come out of youth since ancient times.Of course, the middle-aged Qianlang couldn't just be slapped to death on the beach like this. Since there are already suspected results, then tell your subordinates to move!

Comrade Director solemnly called the bureau and asked them to do everything possible to find out the precise location based on latitude and longitude, and to investigate suspicious situations within the location range.

After tossing his subordinates, he returned to the house and heard that the discussion between the two children seemed to have come to an end.

"...It should also be an interference item, otherwise this F will have no solution."

"Then exclude it according to the interference item first, and then try to translate it."

After a few more minutes, the two children both gasped.

"Is there a result?" Gu Jianyan asked hastily.

Bai Yifei handed him the calculation paper with trembling hands.

[Kill one person every month and offer the place of burial if you have the ability to catch me yanmo]

"Yanmo, we speculate that it should be the signature of the murderer. Because it is an English alphabet, we don't know which two words it is."

"With the latter two letters, I think that should be the latitude and longitude of the burial site."

Gu Jianyan fell into a deep silence facing the calculation paper. Although City K is a big tourist city with a large base of floating population, homicides happen occasionally.But the quality of the police is generally high, and the detection is very fast.This kind of murderer who blatantly challenged the police with extremely bad nature was really unprecedented.

The point is that they really can't find any clues, and they have to rely on foreign aid to decipher the code.It shows that this murderer is not only bad, but also very smart, and he is a criminal with a high IQ who is quite difficult to deal with.

"Yifei, thank you and this kid, I'll take it back to the bureau to study it first."

"You're welcome Uncle Gu, if you have any questions, you can come to us again." Bai Yifei knew that it was not convenient for amateurs to follow up on follow-up searches, so he said goodbye to him tactfully.

The two children waited for Gu Jianyan to leave before they looked at each other, feeling apprehensive and apprehensive.

The murder case actually happened right next to them, and they even deciphered the murderer's provocative letter. This knowledge is a bit creepy for a half-aged kid who is still a high school student.

"No, don't be afraid! I'll cover you!" Bai Yifei puffed out his chest.

Don't be afraid that you still stutter.Of course, Qin Qing knew that Young Master Bai was a little scared in her heart, so she secretly smiled and patted his powerful arm.

"That's up to you, bro."

After Gu Jianyan took away the clues, the progress of the case was never published in the newspapers, nor did he receive any contact calls, as if the whole matter had become a thing of the past.

Soon the winter vacation is over and the new semester begins.

Bai Yifei remembered that Qin Qing had said that he would be asked to participate in the Chemistry Olympiad in July, and it seemed that there was not much time left, so he started to add lessons to himself.

Because chemistry is simpler than physics, the school asked chemistry teachers to add small-class Olympiad tutoring on weekends, in order to allow more students to win awards and obtain extra points for the college entrance examination, thereby increasing the admission rate of prestigious schools.

Bai Yifei studied with his class for a while, and one day he suddenly discovered some patterns like an enlightenment.

His logical thinking ability is not bad, but because he desperately forced himself to follow in Qin Qing's footsteps, he didn't have time to pay too much attention to the relationship between textbooks and textbooks.On the contrary, he always uses rote memorization, which he is not good at, to do more exercises, which leads to half the effort.

The biggest difference between Olympiad and ordinary courses is precisely the way of thinking.Not only can you improve your grades by memorizing more and doing more questions, but more importantly, you can trace the source to find the foundation of knowledge points, master the rules, and respond to changes with the same.

As long as you keep the basics in mind, with his super logical thinking ability, the clues provided in the questions are clear at a glance, and the answers are all in your hands.

In the same way, not only chemistry, but also mathematical physics can use this method.

Bai Yifei paused the cramming method of desperately reading textbooks for senior two and senior three, and started sorting out and integrating all the previous knowledge points.After sorting it out and looking back at the wrong questions, I realized how shallow the knowledge I had before was.

No wonder the most difficult big questions at the end of the exam always fail to achieve high scores!Just thinking about how to match the similarity with the questions you have done before, and copy the process of doing the questions, of course you can't get a perfect answer!

The topic is ever-changing, but it remains the same. Only by grasping the core, can you let yourself be tricky and free.

Now, it is hopeful to be promoted to the top class! ! !

Young Master Bai was so happy from ear to ear for several days. He was thinking whether to tell Qin Qing the good news, but later, his stomach turned bad, and he insisted on holding back and preparing to play some tricks to scare people.

It's a great opportunity, you should make a bet before the exam to get some sweetness!After all, a certain person always used promise to his mother as an excuse, and he didn't let her touch it for several months. Even touching his little hands would get beaten, and his heart was so stuffy.

As the weather gets warmer and the flowers bloom in spring, the school organizes an annual spring outing.

The scenic spots are separated for each year. The first year of high school is the Naijia Lake Scenic Area. There are not many places to play, but for high school students who can get high as long as they have a partner, these are not a problem.

Just thinking of nearly a thousand students sitting side by side in the scenic area is already very interesting!

Lake Naiga is about half an hour's drive from the school. On the day of the spring outing, the students who arrived at the school were all amazed at the neatly lined up buses.Wow, the car is so new!It's rare for the school not to search!

The homeroom teacher who was in charge of discipline was heartbroken. He took the students to the playground and arranged them in an orderly manner. They boarded the car and set off.Forty or fifty students were squeezed into each bus, chattering like a flock of ducks, and it was very lively.

Naijia Lake is characterized by its large area, and there are two scenic spots along the lake, Red Maple Forest and Rhododendron Valley, plus a large lawn for picnics, which is especially suitable for group outings with a large number of people.

At this time, the rhododendrons in the Rhododendron Valley are in full bloom, and there are pink pink everywhere.The schoolgirls were so excited that their eyes were full of love, and it was a joy to take photos with flowers, people and lakes.

Although the picnic area is divided according to class, there is no way to stop the boys and girls with outstanding mobility. After setting up a spot, laying out a picnic cloth and storing things, they all scatter to find good friends to play with.

Bai Yifei didn't even bother to lay out the picnic cloth, so he said hello to Ah Wei and went straight to Class 3.

The compatriots in class 3 are no longer surprised by the non-staff member of Young Master Bai, and when they see him habitually open their mouths, they shout: "Qin Qing, come and pick up your Bai Yifei!"

"Oh!" Qin Qing replied far away, and continued to focus on what she was doing.

Bai Yifei consciously looked for him: "What are you busy with?"

"The rope that binds the picnic cloth is tied into a knot that cannot be untied."

"Let me take a look." Bai Yifei took over the hard work from Qin's talented scholar, who was middle-lower in manual ability, grunted a few times at the dead knot, shook the cloth, and spread it on the ground slowly.

perfect!

I am so awesome!

"Wow, it's ready?" Xiao Pang next to him saw it, and threw himself on the cloth happily: "Shuhu—"

"You'll sit back and reap the rewards." Qin Qing walked around the fat body on the picnic cloth in disgust, put the backpack in the corner, and said to Bai Yifei: "Want to go shopping?"

"Okay." Bai Yifei took out the MP4 while walking, and the two shared a pair of earphones, with the dangling cord hanging between the ears, rippling as they walked.He pressed the music play button, and a clear male voice came out, spreading in his ears.

——"You let me understand what true love is, and you let me feel what warmth is..."

——"You hold my hand tightly and start a journey, taking me to a place I have never been to..."

"Bai Yifei."

"what?"

"Let go, don't hold."

"……Oh."
