As a first-stage magician, there are few people who can surpass his mathematical calculation ability in the entire Biyuan City.

With this kind of ability, the first-class sequence problem in front of you is full of paste at first glance, and even overflowing from the brain with two eyes...... I can't find the train of thought at all!

After studying it for a while, a feeling emerged that with his ability, even if he died in front of the question in this life, he would not be able to make it!

Can......

Such a difficult question, this scumbag, who everyone looks down on, writes quickly without thinking...... Although it is still impossible to judge whether it is correct or not, the steps that appear on the wall have been checked and there are no problems!

Many formulas, even him, need to look at it for a long time and verify it for a long time before they can be determined.

And the other party, as if there is no thinking barrier and no need to check, writes faster and more.

Quan Lao frowned.

"What's wrong?

The old man who had spoken before came to him.

The others came over in unison.

Those who can solve problems here are basically famous super scholars in Biyuan City, and they know each other well.

The level of this Quan Lao, among all people, is definitely the top.

"It's not wrong, it's me...... Some can't understand it......" his face turned red, and Quan Lao's face was full of embarrassment.

At the beginning, with his ability, he could easily understand and check, but at this time, with the more he wrote, many of the contents were beyond the scope of cognition and could not be understood.

"Quan Lao can't even understand...... This guy just said that as long as it is fast, he didn't say that he would be able to solve the ......."

A voice rang out from the crowd.

Even a first-grade magician can't understand it, who can guarantee that it's correct?

What's more, this guy also has a not-so-glorious "criminal record!".

"I don't think it's necessarily right!"

Immediately someone pandered.

Although the previous steps are correct, there are still 108,000 miles away from proving the difficult problem of this first-class sequence.

What's more...... This guy who can't see his face, his previous performance was too bad to be believed.

"Actually...... It's incorrect, we can't read it, someone can definitely see it......"

Seeing that everyone was getting more and more excited, he hesitated for a moment, and Quan Lao suddenly spoke.

"Quan Lao shouldn't be talking about him!"

He ...... Isn't it a retreat impact second-grade magician?"

"It doesn't seem to be, where is the age, the second grade should be hopeless, but the ability should not be underestimated......"

Everyone was stunned, and then someone realized something and looked at it with wide eyes.

"Yes, that's what I'm talking about...... Qiao Zimu, Qiao Lao!"

Knowing that someone guessed, Quan Lao didn't play dumb riddles, and spoke directly.

"He is the former vice president of Biyuan Academy, known as [Mental Arithmetic Invincible], a technique within one product, no matter how difficult it is, there is no need for column and vertical style, more than ten additions, subtraction, multiplication and division, opening squares, decreasing powers, mental arithmetic can be solved!

"I grew up listening to his classes, and now I think about it and it's still shocking, and I feel that it is difficult to surpass ......"

Everyone exploded, full of excitement.

Qiao Lao, with the increase of age, his ability at this time may not be as good as His Majesty Xiao Jin and the demonic Nine Princesses, but he is still the top superlative person in the entire Biyuan City.

No one is disrespectful, no one is dissatisfied!

Especially the mental arithmetic ability, which can be called invincible.

It's just that......

"I know what you're thinking, let me tell you the truth, Qiao Lao is not in retreat, we had tea together yesterday, and it's not too far from here, as long as you open your mouth, you should be able to come over soon......"

Smiling slightly, Quan Lao turned his head and ordered, and a young man behind him immediately turned around and left.

Knowing that they were going to invite this famous celebrity, everyone relaxed, and although they continued to look at the wall, they were not so excited.

Because...... Many of the formulas and theories above are really incomprehensible at all!

"This is the mantra of this year's revision......"

Soon, someone ran out and brought dictionaries and mantra classics, corresponding to the query.

As a result, the more I checked, the more confused I felt.

The steps in front of us are really mysterious, beyond the scope of imagination.

The use of many mantra theorems is simply unbelievable and unimaginable.

Just when everyone was getting more and more confused, a voice full of displeasure rang out.

"The difficulty of the third-class sequence is so great that it has exceeded the scope that Biyuan City can understand...... You say, somebody's solving a first-class sequence? What are you kidding?"

Although the voice is old, it is full of energy, showing the strength of the person who speaks.

Qi brushed his head back, and then saw an old man with a ruddy face, striding over.

I can't tell the specific age, the hair, beard, and eyebrows are all white, but the skin is full of elasticity like that of a young man.

"Old man Joe is here......"

Excitedly, his voice immediately sounded.

The invincible old man Qiao, Qiao Zimu!

A half-step second-grade magician over eighty years old.

"Brother Qiao......"

With a happy face, Quan Lao greeted him.

"Hmm!"

With a wave of his hand, Qiao Zimu raised his eyelids, looked at Shen Zhe, who was in front of the wall, continuing to write, and sneered: "This is what you say, the person who challenges the first-class sequence problem?"

Elder Quan nodded.

"I don't know how thick the sky is...... Let me tell you the truth, this first-class sequence problem, after the ninth princess studied it, she showed it to me, I have studied it for ten days, and I know that with my current strength...... I couldn't answer the plan, so I gave up!"

Qiao Zimu snorted: "What do you mean, this guy who seems to have appeared out of nowhere, is more powerful than me?"

"Elder Qiao has done this question before?"

In the room, the atmosphere is suffocating.

I thought that this first-class sequence problem was the first time it came out, but I didn't expect this old Qiao to do it before......

Moreover, it has not been made yet!

Qiao Lao can't do it, this guy, should it really ...... Just scribble!

"In front of him, we have checked the steps that people can understand, and they are right......"

Knowing the other party's suspicions, Quan Lao said.

"When your disciple came, he told me that he couldn't solve a simple question, how could he solve this kind ......of problem correctly?

Shaking his head, Qiao Zimu stood casually not far from the wall, raised his head and looked at what Shen Zhe had written.

The powerful spiritual power, violently fluctuating, pressed the surroundings silently.

"Huh?"

His eyes swept over the wall, lines of handwriting, appeared in his mind, Qiao Zimu quickly calculated, and after a while, he no longer had the previous contempt, his expression became more and more solemn, his feet were not ding, and the muscles of his whole body were tense.

Zizizizi!

Sweat appeared on the head, because the brain was running too fast, and before it could drip down, it was evaporated and turned into steam and rose up.

Moving slowly, Qiao Zimu walked out of a special step.

"Even the gossip steps have come out......"

Izumi swallowed.

This old friend, he is very familiar with, normal mental arithmetic, standing in place can be completed, first not Ding, and then out of the gossip step, it has already been shown that the soul power is operated to the limit!

Back then, I didn't have to work so hard to compete with people's calculations!

Just as I was about to ask what the calculation was and whether it was correct, I saw my old friend's eyebrows sink, and he couldn't help but take a few steps back, and his face turned pale.

Exhaled, turned his head and commanded, "Bring the pen!"

"Let this most powerful mental arithmetic master in Biyuan City use his pen to check it, even if he does something wrong, it is enough to comfort his life!"

"yes...... I've never seen him this big, and he's never put pen to paper......"

The house was full of shock.

Qiao Lao's mental arithmetic ability is well known to everyone.

The problem that I basically saw could be solved by mental arithmetic, and now I suddenly use a pen to ...... It's beyond imagination.

Call!

With the pen and paper in hand, Qiao Zimu wrote quickly, and pages of paper soon appeared under the pen.

As he wrote, the sweat on his head did not decrease, but increased, and the whole person seemed to become a moving steamer, with white smoke billowing.

Burst!

A mouthful of blood spurted out, and he took a few steps back again, and Qiao Zimu was hit hard.

"Brother Qiao......"

Quan Lao hurriedly came to him.

After swallowing a pill and gasping for a few bites, Qiao Zimu's face recovered, and he turned his head again: "Bring my abacus ......"

"I can't do it with pen and paper...... Can't keep up with each other's speed?"

......

With wide eyes, everyone looked again at the figure in the long coat who was still in front of the wall, writing quickly and without stopping......

Silent!
