When I went out again in the afternoon, the traffic jam on the highway had been cleared, and only some gravel on the side of the road was showing. A car accident was released this morning.

But others will never know that this traffic jam is likely to have been deliberately caused by someone.

"By the way, Lin Tian, ​​did that Sun Decai cheat in the exam this morning?" Xiao Manxuan asked curiously.

"Of course there are, and it is also the most advanced cheating method, high-tech glasses and invisible earplugs, which can avoid detection in the examination room, comparable to James Bond's spy technology in 007." Lin Tian sighed.

"Spy tools can be bought on the black market. As long as you have money, there is nothing strange. You are not from the business circle. You don't know that commercial spies are more common than your cheating students. Which big company does not have commercial spies." The young lady was open-minded and didn't care.

Xiao Manxuan said with a smile: "With your Lin Tian's personality, you must have stopped him from cheating."

"It's just a simple task, why not do it? Hehe, he came to question me afterwards. However, according to him, a set of equipment costs 80,000 yuan. Although 80,000 yuan is nothing to him, he can't cheat. I guess he'll be crazy." Lin Tian laughed.

"Eighty thousand, this prodigal son is really willing to do so." Xiao Manxuan said with great contempt.

"In Sun Decai's eyes, problems that money can solve are not considered problems. If I guess correctly, he will continue in the afternoon." Lin Tian said with a faint smile.

When I arrived at the school, my parents were still surrounded by my parents. Even if the sun was hanging in the sky, I couldn't stop them. It really responded to the saying, I felt sorry for my parents in the world.

Farewell to the eldest lady, Lin Tian and Xiao Manxuan entered the school and went to the examination room respectively.

The afternoon exam is mathematics, which for most people, is the most difficult subject in all subjects. Although it takes a lot of time to take Chinese, Chinese is the native language after all, and it is not as difficult as reaching the sky.

But mathematics not only requires meriting memory, but more importantly, IQ. Therefore, learning mathematics depends on some talent. Among the students Lin Tian knew, many people are ten times more diligent in learning mathematics than Chen Herun, but their learning results are not as good as Chen Herun.

In the morning, Lin Tian could see many students talking and laughing, but in the afternoon, they were all frowning. They took math, and even the students in key classes were 100% sure, let alone students from other classes, except for Chen Herun.

Chen Herun has mastered the basic theorems of mathematics, so no matter how ever the test questions change, he can see the essence at a glance, and of course he can easily solve them.

Other students rely on memorizing mathematical formulas to memorize mathematical formulas. If they take the test type of the question you just saw, they can still solve it, but if they change the type of the question, they will not be able to do it immediately.

Although Lin Tian could not reach Chen Herun's level, it was still not difficult to get into high school mathematics, unless it was advanced mathematics in college, which might be a bit difficult.

Lin Tian sat in the last row, waiting for the start of the exam. Sun De was the last one to enter the exam. Lin Tian paid special attention. This guy was not wearing cheating glasses.

Did I guess wrong? Or did Sun De give up completely even though he knew he could not cheat? Lin Tian was very confused.

After Sun Decai entered the examination room, he performed very honestly. After placing the stationery and ID cards, he sat honestly without any extra movements, nor did he turn around and provoke Lin Tian.

People who don’t know think he is confident in taking mathematics, but Lin Tian knows that Sun Decai’s grades were so poor at all times, whether they were roommates or now.

He didn't cheat, and his grades were not good, but his performance was so calm. With Lin Tian's understanding of Sun Decai, his performance was too abnormal. He was so angry that he was destroyed in the morning.

Had there been a new way of cheating? A flash of inspiration flashed through Lin Tian's mind, thinking of this possibility.

Lin Tian's perspective gaze swept across Sun Decai's body. In his ear canal, he found micro earplugs, but except for the micro earplugs, there was nothing hidden on him.

To play a role, the micro earplugs must be used with the receiver. Therefore, Lin Tian concluded that Sun Decai must have brought the receiver, but it was just more concealed.

The receiver in the morning was hidden in the glasses. Where will it be this time? Lin Tian thought in confusion.

Lin Tian noticed what was on his desk, an admission ticket, a **, two pens, and some stationery used to take math tests.

Two of the pens caught his attention. If Sun Decai wanted to cheat, the signal receiver should not be too far away from the micro earplugs, so the receiver must be hidden beside him.

It is unlikely that the ID will contain a receiver, and the stationery is plastic transparent, even less likely, and in the end there are only those two pens.

The glasses frame is so small that it can hide a chip and circuit board. The pen holder is so large that it is more than enough to hide it. Lin Tian glanced through his perspective and found that the abnormality of one of the pens was discovered. In the pen holder, in addition to the normal refill core, there were also tiny chips and circuit boards hidden.

It is indeed hard to guard against. Even if the invigilator disassembles such a pen, he can only find the normal refill inside, but he cannot find the sealed receiver in the pen holder. It is possible to see it unless the pen is smashed.

However, without evidence, it is impossible for the invigilator to smash the student's pen, so those who invented these cheating devices are well aware of the way of spies.

If it weren't for the ability to see through, Lin Tian wouldn't have discovered the truth about the pen holder.

As expected, he is really a spendthrift. He broke one and bought another one immediately, Lin Tian murmured softly.

Lin Tian guessed right. After Sun Decai questioned Lin Tian in the morning, he went to find those people and bought a cheater. In order to prevent Lin Tian from destroying him, he also changed his glasses to pens.

After thinking about it, Sun Decai felt that his plan was not detailed enough, he was not myopic, but he wore a pair of glasses. At the critical moment of the college entrance examination, it would definitely attract the attention of those who were interested. Now, he simply changed it to a pen.

The test paper was quickly sent out, and Sun De picked up the pen and wrote the test paper honestly. In fact, he could clearly hear the answers to the test questions in his ears.

He was also a little proud. This time he finally avoided Lin Tian. He held the pen in my hand. Can Lin Tian still snatch my pen? Sun De thought proudly.

But he had just written several multiple-choice questions, and suddenly felt that the pen holder was not under control, and the tip of the pen suddenly slides on the test paper, almost breaking the test paper.

What's going on? Sun Decai picked up the pen and checked it. He found no problem. When he thought it was an accident, the sound in his ear suddenly turned into a murmur.

He was very familiar with this noise because he was quarreled by the noise for two hours in the morning. In the end, he couldn't help but hand in the paper in advance, but he couldn't do it anyway.
Chapter completed!
