In the afternoon, there were two consecutive biology classes, and in the past two years, the score of biology in the science and science has gradually increased, from more than 70 points to 90 points, so the number of classes has begun to increase.

To say that the subject of biology is called the liberal arts in science by many people, because it needs to memorize and memorize a lot of content on the premise of understanding the basics, which makes many science students have a big headache.

Originally, Wu Bin planned to let all the subjects go hand in hand, but some of the problem-solving ideas that Liu Yushan gave him during the lunch break were like top-level strategies, so he couldn't wait to try them one by one, so the whole person was in a state of obsessing with mathematics, so today's plan to watch high school biology was temporarily canceled.

Wu Bin, who has a method of solving problems, is now like a bamboo, and several questions that stumped him for half a day yesterday have been solved one by one, but this sense of pleasure suddenly stepped on the brakes when he was studying at night, and stopped in front of a quadratic function problem.

Wu Bin, who grabbed his hair, looked up at Gu Fan, who was at the same table, and found that he was staring at a physics problem in a daze, hmm...... It's a real trance, and God doesn't know where to fly.

I can't count on it. ’

Wu Bin instantly vetoed the option of [Saving the Same Table].

Then Wu Bin glanced at Pei Jiamin again, as a representative of the mathematics class, her math scores were naturally the best in the class, but Wu Bin was really not very familiar with her, and she didn't know how to speak.

'Alas, it is really easy to go from thrift to luxury, and it is difficult to go from luxury to frugality. ’

After experiencing the simplicity and ease of understanding someone to talk about, Wu Bin no longer wants to experience the feeling that he can't solve a problem if he wants to break his head.

Although he himself is a character who likes to become stronger by his own efforts, he must first understand the most basic rules of the game.

"The basic capacity of the host has been slightly improved, and the energy can be activated as a backup plan4."

Just when Wu Bin was in a dilemma, a strange voice suddenly sounded in his brain.

Wu Bin, who was startled, looked around, but didn't find anyone talking.

"Alternate option 4 has been successfully activated, and the host can now open the minimum tutorial every 24 hours to help with learning, with a duration of three hours."

'What's the situation!?' Wait a minute! This voice ......'

At this moment, Wu Bin suddenly remembered that it seemed to be this voice that sounded in his head when he fell down yesterday!

"What the hell are you!?"

Wu Bin, who forcibly suppressed his inner turmoil, asked in a low voice, but did not get any response.

'Calm down...... Calm down...... What did that voice say just now, tutorials? ’

"Does the host need to open the minimum tutorial?"

Then the strange voice suddenly rang out.

'Host? Me? Then open ...... Turn it on. ’

Anyway, they had already been tricked, and Wu Bin simply let it go, and decided to figure out what it was first.

"The lowest level tutorial has been opened, and the remaining time is 2 hours, 59 minutes and 59 seconds."

'What are you?' ’

"Sorry, this issue is not within the scope of inquiry."

'Gan...... Is such a simple question too much to ask? ’

Wu Bin, who rolled his eyes, suddenly remembered that the voice just now seemed to be saying that it could help him learn, so he pointed to the quadratic function problem with an attitude of trying.

How do you solve this problem?' ’

'The maximum value of the quadratic function is only taken from the endpoint value or the axis of symmetry, and it is now known from the title that the domain is defined from 0 to m......'

Listening to the strange voice in his head, he really began to explain the topic for him, Wu Bin was stunned, what is this? Xiaobawang learning machine? But why did it run into my head?

"Please listen carefully."

When Wu Bin was extremely inexplicable, the decibel of the voice suddenly increased by a few points, attracting his attention back.

'Oooh...... Listen, listen. ’

"Ask the host to answer the formula for the axis of symmetry."

'Huh? Oh, that, x is equal to minus 2 b? ’

"Correct, then let's move on."

‘WTF！？ Even with interaction? ’

Then, in this wonderful interaction, Wu Bin got the answer to the quadratic function problem, and at the same time, the strange sound disappeared.

"Smack!"

Wu Bin slapped Gu Fan's thigh violently.

"Damn, what are you doing!?"

Gu Fan, who was in pain, glared at Wu Bin.

"You have a mosquito in your leg, I killed it for you, don't thank me."

After Wu Bin finished speaking, he also gave Gu Fan a friendly smile.

"Ah...... Oh, oh, it's good if you tell me next time, I'll fight myself. ”

Gu Fan, who accepted Wu Bin's statement, rubbed his thighs and continued to look at his textbook.

There was a pain in the palm of my hand, and it didn't seem to be a dream. ’

After confirming that he had really encountered this kind of supernatural event, Wu Bin didn't show too much panic, or he actually looked forward to this kind of thing happening to him, and at the same time probably knew how he suddenly fell in love with learning.

From the current point of view, this learning system should not harm him, although he can't put his mind at once, but he can only let go, after all, he has no solution, no, he can't rush to the hospital and tell the doctor that there is a voice in his head that is teaching him how to solve quadratic function problems, right? Then I will probably go straight to the psychiatric department.

'If you come, then you can be safe, Lao Tie, how to solve this problem? ’

Wu Bin, who has a big heart, pointed to the next question of "homogeneous heterogeneity".

……

"There are 5 seconds left in the minimum tutorial time, and the system is about to shut down."

"Don't, wait, you tell me the conditions of this odd function."

Wu Bin was in a hurry, and accidentally shouted out his words, which attracted the sideways eyes of the surrounding crowd.

"Ahem...... Gu Fan, what do you mean? ”

Wu Bin looked at Gu Fan, who was about to pour some water, and asked.

"What? Say what? Gu Fan looked back with question marks on his head.

After listening to the conversation between the two, the people around them lowered their heads again, and even a few of them laughed disdainfully, probably thinking that the two scumbags were in a hurry to go to the doctor.

"It's nothing, you can drink water." Wu Bin waved his hand at him.

"You're poisonous today, aren't you?" After Gu Fan sighed, he took the water cup and walked towards the water dispenser.

'Lao Tie, are you still there?' What are the conditions for this strange function, Lao Tie? ’

After resolving the embarrassment, Wu Bin immediately went to ask the system again, but found that there was really no response.

Alas, it's a pity, the problem-solving ideas taught by this system are a little easier to understand than Mr. Liu's, but this time is too short, tsk. ’

However, the knowledge points taught by the system just now are enough, and the remaining self-study class was digested by Gu Binquan.

On the way back to the dormitory, Gu Fan hooked Wu Bin's neck and asked, "I suddenly felt that you were acting very wrong just now, it can't be that you studied too hard, and you entertained me, right?" ”

"Am I like that?"

"Like, aren't you that kind of person?"

"Tsk, I was discovered by you, I deserve to be friends at the same table, but I can't hide it from you."

"Then ...... Hey, you kid, don't run! Eat me a trick Foshan no shadow feet! ”
