In the first political class and the second math class, Shi Tiexin has been competing with his four arithmetic problems. The teacher of the mathematics class, Teacher Chu, the head teacher of Class 28, also discovered Shi Tiexin's abnormality, but this Teacher Chu didn't care about him. In his opinion, it is already rare for the bastards of the garbage class to be able to sit here honestly and not look for trouble.

At least didn't you yell and disrupt order in class, and then beat up the math teacher and homeroom teacher, and ask for anything else?

Very satisfied.

Therefore, this teacher Chu finished his class and left, never delaying the class for a minute, and never said a word. The bastard of the garbage class, it's not worth his time to waste time.

When the bell rang for the end of the second class, Shi Tiexin also took a long breath and stood up. He stood up, moving his sore wrist as he walked to the toilet to drain the water.

"That's awesome!"

"Xiu'er, can you still sit down?"

"Dick Cock!"

In front of me, there are inscription boards constantly swaggering out, one after another. The stars snapped out of the frame, all crashing into the progress bar. The icons representing the progress of the minor were completely filled, and this time three extra stars were blown up, all of which hit the progress bar.

The progress bar keeps rushing forward, all the way up from a scale of about 70. After an hour and a half of concentrating on studying, let the progress bar rush towards the end. When Shi Tiexin walked to the toilet and began to release water, the progress bar went to the last few scales.

The badge of the word "Enlightenment" on the left side of the horizon suddenly shone brightly, and several rotating pillars of light were released with a brush, and then the entire body flew up into the progress bar, completely disappearing.

It seems that the "fully comprehended" buff has come to an end.

But it also contributed its last bit of strength.

[Basic Mathematics Level 1 Cultivation Progress Improved to Excellent]

The progress bar suddenly lit up with a bright light, and this time the bright light was even cooler than the last time it was full. The word "Excellent" on the right side of the progress bar suddenly expanded, obscuring most of the field of vision, and then slammed down to the left.

Boom, the ground shook, and the word "excellent" replaced the original "good" position, sitting on the left side of the progress bar, becoming a new starting point. An illusory empty bar extends to the right, and a new lettering appears at the end of the right.

【Depth】

Shi Tiexin trembled three times, and the toilet in front of him suddenly became tasteless.

Excellent! The first weight of my basic mathematics is so excellent, and the real speed is really good, thanks to you, the champion stone!

Moreover, the realm of a further level under the excellent is indeed "profound". Shi Tiexin has always felt that there must still be a realm, and now it has finally appeared. Yesterday, when observing the attribute description of the minor secret record, Shi Tiexin had already noticed this word. Now, this realm is also beginning to beckon to itself.

Then charge towards this realm non-stop!

Shi Tiexin returned to the classroom, sat down, took out a new workbook, and prepared to continue practicing. But when he opened it and looked at it carefully, he frowned.

He suddenly felt that this exercise book was too simple for him. Or rather, it's too bland. Looking at these simple additions, subtraction, multiplication and division, it is completely impossible to arouse his desire to challenge, and he is not energetic at all. And he is confident that he will definitely do well in this level of questions, and no matter how much he practices, I am afraid that there will be no improvement for him.

I picked up the pen and tried to do it, and sure enough, it was very smooth. The topics that used to require careful consideration are now not difficult for him at all. And he found that the effect of doing this kind of workbook was really reduced. I did three sets of practice questions in one go, and I was supposed to give at least seven or eight stars, but this time I was only given one star.

It's too slow.

"Could it be that the ordinary-quality minor secret record is no longer applicable to me?" Shi Tiexin realized in his heart, looked at the unfinished workbook, and finally put it down.

Time is limited now, and it is necessary to study in the most efficient way.

Rummaging through the hole in the table, Shi Tiexin took out a new minor secret book.

【Quality: Boutique】

[Progress: 0%]

[Attribute 1: High difficulty.] This minor is more difficult, and the first level of basic mathematics cannot be used if it does not reach the passing level, and if it does not reach the excellent level, it will slow down the use speed according to the level. Correspondingly, further increase the cultivation speed by 20%]

This minor secret book called "Four Advanced Arithmetic Exercises" is the same fine secret book that I picked up and put down at the beginning. At that time, I was just qualified and was directly beaten by the high-intensity and difficult questions that swarmed out, and I escaped. But after a day, Shi Tiexin will challenge again.

Turning over the workbook, Shi Tiexin began to work on the question as if he was facing a great enemy.

Well......

Can you read ......

Can understand -

It can be done!

This difficult question is not even difficult!

Shi Tiexin's heart was extremely happy for a moment, and the operation of his subordinates became more and more smooth. He just felt that this workbook was just right for him now. It's not too simple and makes him feel bored. It's not too tough, and there's a speed penalty for him.

It's taking advantage of it, it's really just taking advantage of it!

Click, click Zhou Nan, who was not far away, was very curious, and he didn't know why this big guy could make the momentum of his eldest brother playing "King of Boxing" in the game hall when he did a primary school question. Curiously, I leaned my head and took a look, oh mom, dizziness, headache!

Zhou Nan, who was defeated in an instant, looked at Shi Tiexin, and couldn't help but feel a sense of awe in his heart. Although he has always been in awe of Shi Tiexin, this time it is a different kind, and it is the awe of the scumbag who looks up to the big man of the school.

I can't do any of this kind of questions, but this boss is a book as soon as I do it!

The nickname of Zhuangyuan Stone is really not called in vain, the big guy who is a scholar, it is really terrifying......

In the fourth class in the morning, when he was about to end class, Shi Tiexin finally rubbed the bridge of his nose and stopped his crazy charge. No, I'm so tired. After a whole morning of high-intensity and high-concentration cultivation, even Shi Tiexin couldn't hold it anymore. The cultivation level of essence and mind qi is still too low, and it is already the limit in the morning. Under the exhaustion of thoughts, no matter how reluctant you insist, you can only make mistakes and omissions, and it has no effect.

The stars flew out in a row, and the progress bar rose by nearly twenty-five ticks. Even if you use the Secret Record of the Boutique Minor, the speed will inevitably decrease. But this kind of progress is still within the acceptable range, and if you calculate it, you can achieve "profundity" in about a day, which is completely drag racing!

For now, let's take a break.

Stretching his waist, Shi Tiexin relaxed deeply. As soon as I relaxed, I realized that something was wrong.

The teacher on the stage was still teaching unhurriedly, but the atmosphere under the stage had changed subtly. Some people put away their pens, some people were eager to try, and some people even leaned out of their seats half-stretched, making the movement of athletes preparing to start.

What's wrong with these guys?
