Su Shuangjiang didn't know that some students were laughing at him. Even if he knew, he didn't care. He came to the flower bed downstairs. Because of the competition, the surroundings were quiet, and the sun was not hot at this point. Su Shuangjiang, who was sitting under the tree blowing the cool breeze, couldn't help but stretch.

He took out his mobile phone and saw that it was not yet nine o'clock, and there was still more than half an hour before the next league test.

"Looks like I can take a good rest." Su Shuangjiang wanted to know how many people in the family did not do the questions properly, so he sent a message to Lu Shaochuan.

Soon the opposite side replied: "Have you finished the exam?"

But in the face of Lu Shaochuan's question, Su Shuangjiang ruthlessly told him: "You are actually playing with your mobile phone? Add a big question in the afternoon."

At the same time, Lu Shaochuan, who was clutching his hair and thinking about a math problem in pain, heard the phone vibrate, opened the message, and almost vomited blood.

This guy is actually fishing! Excessive! unacceptable!

Lu Shaochuan never thought that Su Shuangjiang would actually fish and test him, when did this person become so cunning!

But Lu Shaochuan is not an honest, kind and good person. He took pictures of the other three scumbags making noises and sent the video to Su Shuangjiang.

Sure enough, the other party's response came: "They added two big questions in the afternoon."

Now Lu Shaochuan is finally satisfied, it doesn't matter if he is caught fishing, the most important thing is that he must drag others into the water!

The other three scumbags who were still making a fuss didn't know that they had been sold by their unscrupulous companions.

When Su Shuangjiang was thinking about a new topic under the tree, he suddenly saw a figure jumping down from the fence not far away, and then quickly disappeared into the building in front of him.

This figure does not look like a student.

However, that person had disappeared, and even if Su Shuangjiang wanted to confirm, he couldn't confirm it.

At 20 minutes, the bell for the end of the exam rang, and at this time the students handed over their papers and left the exam room.

However, Su Shuangjiang, who was sitting downstairs, heard a scream of pain. He looked up and found that the corridor on the second floor was in chaos again.

Soon the invigilator came out of the exam room and walked towards the stairs.

Su Shuangjiang noticed that the stairs happened to be on the side of the examination room where he was sitting.

The screams disappeared, replaced by the boy's crying and the teacher's cursing, but Su Shuangjiang still didn't know what happened.

Five minutes later, he heard the sound of an ambulance.

At this time, Ran Ran and Xun Li also came out, and the expressions on the faces of the three were not very good-looking.

"What's the matter? What happened?" Su Shuangjiang walked over to them and asked, with this expression it seemed that the matter was quite serious.

Xun Li covered his eyes with his hands, took a deep breath, and slowly told Su Shuangjiang what had just happened.

"Someone fell on the stairs, their hands and feet were broken, their heads were full of blood, and more than one person was injured." Some were crying softly, but those who didn't cry didn't know if they were in a coma or what?

Moreover, the picture was really bloody, and a group of high school students were almost stunned when they saw these pictures.

When the ambulance personnel carried the stretcher up and down, Su Shuangjiang saw several severely injured students.

This is not like an ordinary accident of falling down stairs... Even if someone did fall, how could it be possible for so many to fall at the same time.

The injured students were quickly taken to an ambulance. Su Shuangjiang went upstairs to take a look. Sure enough, the stairwell on the third floor was covered with blood, which looked particularly oozing.

However, in addition to the blood on the ground, Su Shuangjiang also noticed unusual marks on the handrail next to him.

He leaned over and looked at it, and he smelled the smell of oil. With the traces of the palms on it, it was hard not to think that someone had deliberately smeared oil on the armrest.

Several teachers in charge of invigilating the exam have big heads. No one could have imagined that such an accident would happen in this year's math competition.

Su Shuangjiang could see the oil stains, so naturally they could see it clearly, and they even wondered if someone deliberately wanted to harm these students.

Generally speaking, even if you accidentally slip and fall on the stairs, as long as you hold the handrail, you will not fall.

But now that the handrail is smeared with oil, how can they grab it? Not only the handrail, but they also found signs of oil on the other side of the wall.

Because several students were involved, finally the teacher and the school decided to call the police and ask the police to find out who the murderer was.

However, because of this incident, many students were quite absent-minded during the second test.

When the invigilator saw this, he knocked on the table on the podium and reminded them: "Don't think about other things, the second test is more difficult than the first test, so focus on preparing for the competition."

Su Shuangjiang rested his chin in one hand and yawned boredly.

The second test has only four questions to answer, but the score is 180 points. The same second test is much more difficult than the first test. The content in it is in line with the content of the International Olympiad, and even some of the content is outside the syllabus.

But even with this difficulty, Su Shuangjiang still frowned and began to calculate without abruptly.

In this test paper, the most difficult thing is not plane geometry. The last two 50-point questions are algebra and combination, and they are both proof questions.

Su Shuangjiang read the paper carefully, thought about the knowledge involved in each question, and then began to write.

This time, it took him a long time for the second test, especially the latter two major problems of proof.

The second trial lasted for two and a half hours. After Su Shuangjiang finished writing the papers, he raised his head and glanced at the time. It was only ten past eleven, and there was still one hour before the end of the competition.

He twisted his neck, stood up slowly, and handed over the paper to everyone's horrified eyes, then packed up all his things and left the exam room alone.
