After arriving at Yuan Feng's house, Jiang Xin saw through the window of the Space Building that He Chengyan was the only one there.

He Chengyan was answering the phone in the study, and suddenly frowned, and said to the phonephone, "I'm a guest here, let's talk back." ”

After hanging up the phone, he whispered into the air, "Xinxin, are you here?" ”

Jiang Xin was surprised, Brother Cheng Yan obviously didn't see her, but he actually knew that she was coming?

Straight out of space.

appeared in front of He Chengyan.

"Brother Chengyan, how did you know I was here?"

He Chengyan explained good-naturedly, "Because I suddenly smelled your scent just now. ”

Jiang Xin sighed, "In this case, wouldn't my stealth ability be useless in front of people with a keen sense of smell?" ”

"Think so. Any ability has its pros and cons. No matter how powerful an ability is, it has weaknesses. ”

"Understood."

"Xinxin, is there something wrong with coming to me?"

"Yes. Brother Chengyan, I want to trouble you with one thing. ”

"Just say."

He Chengyan looked at Jiang Xin, as if to say, everything has me.

Jiang Xin smiled slightly, "Help me check Zhao Bang's parents to see if they have any criminal behavior." ”

He Chengyan didn't ask the reason, and replied with a good word.

Jiang Xin no longer bothered He Chengyan, entered the space, entered the destination on the screen, and left.

He Chengyan's face was calm, and he smelled Jiang Xin's smell getting farther and farther away, before he picked up the phone and made a call again.

Space took Jiang Xin back to his residence.

Jiang Xin glanced at the screen, the screen was already black, and he could no longer enter the destination to go somewhere else.

"Kim, you help me keep an eye on the screen and see how long it will take to turn on again."

Xiao Jin jumped in front of Jiang Xin and responded, "Okay." ”

Jiang Xin needs to find out the law of spatial movement, and whether the screen can be activated is the key.

Jiang Xin stepped out of the space, sat at the desk in the bedroom, and flipped through the math textbook.

Thinking of the math competition in the past ten days, Jiang Xin was a little excited.

She knew that it was not enough to just read the textbook, but also to do more math competition problems.

At present, there is no question type in hand, and the bookstore does not sell it, so maybe you should give Mr. Zhou a call.

Thinking of this, Jiang Xin walked out of the bedroom and went to the hall to make a call.

Soon, Mr. Zhou answered the phone.

As soon as he heard Jiang Xin's voice, Teacher Zhou was very happy, "Jiang Xin, are you back?" It's earlier than I expected, so I can review the math questions earlier. ”

Hearing this, Jiang Xin could guess that Mr. Zhou had prepared the math competition mock questions in advance without asking.

"Teacher Zhou, I also want to do the math competition questions earlier."

Teacher Zhou responded on the phone, "When you come to school tomorrow, I will prepare a book for you to contest questions." ”

"Okay, Mr. Zhou, thank you!"

"You don't have to thank me now, you will thank me when you get good results."

"Teacher Zhou, don't worry, I will not let you down."

Jiang Xin is full of confidence in this mathematics competition.

She believes that after doing the relevant question type, she can draw inferences from others.

At seven o'clock the next morning, Jiang Xin walked to the door of Mr. Zhou's office and knocked on the door.

As soon as Teacher Zhou saw Jiang Xin, he immediately said, "Come in!" I've given a set of math competition mock questions, you can do it. ”

Jiang Xin walked to Mr. Zhou's desk and took a handwritten test paper.

Teacher Zhou then handed Jiang Xin a ballpoint pen and two pieces of straw paper, and continued, "Just do the questions in my office, and I will tell the other teachers that your time will be at my disposal for the ten or so days before the math competition." ”

Jiang Xin nodded, didn't say much, sat at the table and began to do the test papers.

There are 10 application questions in the test paper, each of which is 10 points.

In less than half an hour, Jiang Xin finished the test paper and handed it to Teacher Zhou.

Teacher Zhou corrected the test paper as soon as possible.

Five minutes later, after the correction, Jiang Xin scored 100 points.

Teacher Zhou danced happily, "Jiang Xin, you are the best student I have ever taught, and you have done the best in the math competition!" ”

Being praised by Teacher Zhou like this, Jiang Xin became more confident.

"Teacher Zhou, why don't you give me another set of questions?"

Teacher Zhou nodded, "Today's set of questions is of medium difficulty, and I will take the time to give you a set of difficult competition questions later." In the afternoon, you come to my office to do the questions. ”

"Okay."

Jiang Xin just planned to leave.

was stopped by Teacher Zhou, "Wait a minute." ”

Jiang Xin stopped, "Teacher Zhou, is there anything else?" ”

Teacher Zhou handed Jiang Xin a handwritten math study book, about five centimeters thick.

"You take it back and do these questions as soon as possible. Each question is followed by an answer that I wrote, you cover the answer first, write the answer on scratch paper, and then see the answer I write. ”

"Okay."

Jiang Xin took the exercise book with both hands.

Although Mr. Zhou did not say the origin of this workbook, Jiang Xin could guess that it was accumulated by Mr. Zhou in recent years.

In these days, it is really hard to find such math competition workbooks.

At about twelve o'clock in the afternoon, Jiang Xin returned to his uncle's house.

As soon as I entered the door, I saw He Chengyan's figure.

Jiang Xin walked up to him quickly, "Brother Chengyan, have you had lunch?" ”

He Chengyan said mildly, "I've eaten it." I came here to tell you that you asked me to check the matter, and I found it. ”

Jiang Xin looked surprised, "I didn't expect it to be so fast." How, is there evidence of a crime? ”

He Chengyan handed Jiang Xin a brown paper bag, "The materials are all here." You watch it first, and after reading it, you make a decision. I have something to go back to Kyoto, and I'll come back to see you when I have time. ”

Jiang Xin took the kraft paper bag, with reluctance in his eyes, but he also knew that Brother Cheng Yan had a heavy responsibility and could not stay in Yang County forever, so he didn't say anything to keep it, but said softly, "Brother Cheng Yan, I'll send you." ”

He Chengyan saw the reluctance in Jiang Xin's eyes, and rubbed her head lightly, "I heard that you are going to participate in a math competition, waiting for your good news!" ”

The corners of Jiang Xin's mouth went up, and his eyebrows curved, "Okay." ”

watched He Chengyan leave.

After lunch, Jiang Xin went back to the bedroom to read the information in the brown paper bag.

According to the data, Zhao Bang's father, Zhao Min, is the purchasing manager of the cotton mill in Lixian County, and he took advantage of his position to accept kickbacks. Usually love to put on an official show, love to take advantage of others, similar to the seizure of Suhua's hens There are many behaviors, too many to mention.

Zhao Bang's mother, Wen Guixia, does not work at home, but receives the salary of the cotton mill.

Jiang Xin knew that this evidence was enough to send Zhao Min to prison.

As for Wen Guixia, at most, the cotton mill recovered the wages that had been paid.

In the end, Jiang Xin decided to anonymously send the evidence to the relevant departments in the county.

Time flies, and in the blink of an eye, it is the day when Jiang Xin goes to the city to participate in the math competition.

vigorously borrowed a car from the factory to send Jiang Xin to the city, and Mr. Zhou personally accompanied him.

Jiang Xin walked into the examination room with a relaxed pace, found his seat and sat down, waiting for the invigilator to send the competition papers.

When she looked up, she saw someone she hated.

One of the invigilators turned out to be Zhao Bang!
