Wu Chen left his seat and slowly walked to the podium. Zhang Hao whispered from the side: "How about we make a bet? If you do wrong on this question, just give me your position. "

Wu Chen turned his head to look at Zhang Hao, as if he was looking at a child, and spoke frankly: "Fine, if I'm doing the right thing, then in the future, don't spew feces in front of me."

Zhang Hao forcefully suppressed his anger from getting humiliated, and snorted. "It's a deal then!" Then, as if he had won for sure, he sneered in his heart. This special examination method is one of the hardest math problems in high school. You, a trash who sleeps all day long, I don't believe that you can learn it just because you said that you should study seriously.

As a bookworm, he still had a deep understanding of mathematics. Some math problems were not only related to the methods used to solve them during lectures, most of the time, it would also involve things he had learned in the past. Just listening to this lesson was useless, which was why Zhang Hao was so confident.

Wu Chen thought that he would be able to obtain ten points of luck value in a while.

He walked to the podium and looked at the title on the blackboard: "The three vertices of ABC are on the ellipse 4x2 + 5y2 = 6, where A and B two points relate to the origin O symmetry, set the slope k1 of the straight line AC, and the slope k2 of the straight line BC, then what is the value of k1k2?"

Wu Chen did not think too much into it. He picked up a piece of chalk and wrote down the steps and answers to the questions.

Looking at this scene, Zhang Hao who was filled with disdain, was completely stunned, he looked at the blackboard in disbelief, and muttered to himself: "Impossible, such a difficult math problem, how could he do it, and how could he do it so easily?"

As he spoke, he rubbed his eyes and realized that the answer on the blackboard had not changed at all. A strong sense of jealousy arose in his heart.

Math teacher was also shocked by Wu Chen's performance. At first, he thought Wu Chen was just trying to act cool in front of the female students, but he didn't expect him to really have such a trick up his sleeve. He praised: "Looks like you took this lesson seriously, teacher is very pleased."

Receiving Math teacher's acknowledgement, all the students below the stage had faces of astonishment. Wu Chen actually really knew how to do it, and they were still confused about the question, unable to come up with an answer no matter how hard they thought.

'Could it be that it's really like what he said? If he didn't learn it previously, he would only be disdainful. But if he really wanted to learn it, that is very true … '

Was it a simple matter?

Class Rep Lin Jiajia watched as Wu Chen easily answered the question, and also looked at him with a complicated gaze. A strange feeling started to appear in his heart.

Zhang Hao carefully looked at the steps Wu Chen was taking to solve the questions, trying to figure out some of the details. However, after looking through it several times, he still could not find any flaws.

"Impossible, Wu Chen, you must have seen the answer." Zhang Hao was still not giving up.

Wu Chen laughed indifferently: ", are you thinking of going back on your words?"

"Unless you can explain the theory behind this question, how will you know if you can read the answer or not?" Zhang Hao seemed to have found a lifesaver, he would not let go even if he were to die.

Wu Chen muttered to himself for a moment, then nodded his head: "Then I'll make you convinced of your defeat. Because the value of k1k2 is required, we can get the value of k1k2 from the root of the problem. By simply drawing, we can get the value of k1k2 which is the easiest to calculate. Let A and B be two vertices on the long axis of the ellipse and C be a vertex on the short axis of the ellipse respectively. In this way, we can directly confirm the intersection point and simplify the problem. From this we can get the value of k1k2 as -4/5. "

After he finished speaking, Wu Chen grinned: ", do you understand what I'm saying?"

Zhang Hao's face turned ashen

As if a defeated rooster, he powerlessly sat down and turned around, forgetting the place Wu Chen was sitting at. He glanced dejectedly at the beautiful goddess who was smiling at him in the end, only leaving him with an unwilling expression.

The students below the stage could not help but whisper: "Damn, how can this Wu Chen suddenly become so powerful. His previous math results were never that great, to think that he can even solve such difficult math problems today."

"There are so many math questions, it's not strange for me to be lucky enough to understand one or two of them. Just one or two of them is just a test or two. The exam is the final test to test a person's learning results."

"That's true."

Most of the students with better results than Wu Chen were forcing themselves to use this excuse to comfort themselves, so as to improve their mental state a little.

Math teacher spoke up at this time: "has done very well in answering the question this time, it seems like he was listening to it seriously. You all must learn from him, don't disappoint me. "Alright, you may leave."

"Yes." Wu Chen returned to his seat and the system's voice sounded out.

"Congratulations Host, you have successfully slapped the face of Student Zhang Hao, you have obtained ten points of luck value, a total of twenty points of luck value. Do you want to draw now?"

"Keep it, next time we'll just smoke ten times and stimulate it a little." Wu Chen waved his hand.

Zhou Ziyu looked at the triumphant return of Wu Chen, and jokingly said: "Congratulations to Student Wu on your triumphant return, your classmate here, shouldn't I properly celebrate for you?"

Wu Chen shuddered, he felt the alluring beauty beside him, and an evil fire started burning in his lower abdomen, especially against the delicate undulations, his hands seemed to be unable to control himself and wanted to climb up the cliff.

At this moment, the system's voice rang out once again.

"Congratulations to the host for successfully stimulating the most primitive human desires, obtaining a joyous life mission. Within three days, come personally to Zhou Ziyu, you will be rewarded with a secret manual that has a total of ten thousand. After learning this secret manual, you can fight against ten people without any external assistance, but you are unrivalled under the heavens, but you do not have any additional luck value, do you want to accept?"

Wu Chen who had been in a struggle the entire time was awoken by the system's voice, looking at his sinful hands, he almost climbed to Zhou Ziyu's peak and gasped for breath. Luckily, he was awoken by the system in time, otherwise, he would not be able to hold back and do unforgivable things, he would not have the face to sit in this position ever again.

With that in mind, he quickly immersed himself into the system.

"It would be invincible even if we fought ten. System, your bullsh * t is really too much." Wu Chen laughed.

"If an ordinary person can fight against ten of them, wouldn't he be considered invincible? I have reminded you many times, do not have so many strange ideas, it is impossible for you to fly in the air, escape the earth, and shatter the void. If you honestly walk, you will marry a rich and beautiful woman, and walk the path of the peak of your life.

"% x …" Wu Chen was already powerless to retort at this weird system.
