"Hehe, let's look at the battle first, you pay attention to those numbers first......" Chen Lao saw that Xiao Ming was full of confusion and prompted. Xiao Ming can be curious, doubtful, and yearning, which is a good thing.

"Hmm!" Xiao Ming nodded, suppressed the doubts in his heart, and continued to watch the battle in the distance.

Shi Yan and Lu Yi's battle has now formed a large area of numbers, and the three zhang space around the battle between the two of them is full of numbers of different sizes, these numbers, they collide in the air, and they all make a roaring explosion sound, each number touches, and the energy that bursts out is equivalent to the strength of Xiao Ming's full force to hit the eighty-eight multiplication formula.

Immediately, in the midst of a digital connection, the sound of the two pens meeting came with a roar, and in the area surrounded by numbers, the two had already met head-on.

"Xiao Ming, look, that number 2, 3, 5, 7, why do you want to collide with 4, 6, 8, 9, pay attention to ......" Old Chen's voice sounded again.

Xiao Ming immediately looked over and found that the numbers around Shi Yan and their battle were not colliding randomly, as if each number collision had its own unique rules, especially after Chen Lao pointed out, Xiao Ming found that these numbers collided very regularly.

"Yes, Old Chen, why do those numbers collide?" Xiao Ming asked involuntarily. You must know that the numbers of one, two, three, four, five, these numbers are the basis for cultivating immortals, even if Xiao Ming did not have a first-year cultivation, he had already learned them. These basic knowledge are roughly taught in kindergarten.

These simple numbers are just the symbols that form the equation and form the spell. It stands to reason that it is not aggressive. But the numbers in front of him, each of them was full of offensive power, which was the most incomprehensible to him. If you can casually understand the truth of this, then you only need to attack a few numbers casually in the future, and you don't need to play the formula.

"Hehe, that's the use of mathematical laws. Don't look at these numbers as a series of simple numbers, but do you pay attention, are these numbers really the same as the numbers you usually use?"

"Different?" Xiao Ming couldn't help but look at those numbers carefully, at this moment, his eyes happened to see an 11 float out of Shi Yan's pen, and then, this number eleven, there was a faint wave of aura, and when this number 11 came out, between a breath, the number 11 automatically absorbed a large amount of aura in a short period of time. Then, the number 11, which absorbed a certain amount of aura, accelerated violently, and actually hit the numbers 9 and 10 beside Lu Yi. Suddenly, these three numbers immediately erupted with great power, and the power was no less powerful than the attack strength of the Fractional Golden Dragon before Dong Ruoyu.

"Old Chen, those numbers will automatically absorb aura!" Xiao Ming was taken aback and immediately said.

"Huh...... These numbers, when they were typed out by Shi Yan and others, Shi Yan attached the numerical laws he comprehended to these numbers. The laws of mathematics, just like if you use Gaussian addition, the subtle principles in them are naturally much more powerful than ordinary attacks. Now the law of these numbers that he has given is called the law of prime numbers, that is, every number, only the number 1, and himself is his divisor. ”

"And the law of composite numbers played by Lu Yi is the law equivalent to the law of prime numbers typed by Shi Yan, and these regular numbers are naturally special than the ordinary numbers you usually type. Chen Lao explained.

"Uh...... This ......"

Xiao Ming scratched his head, his eyes still full of doubt. What Chen Lao said clearly, but he didn't understand it very well. After all, Xiao Ming hasn't mastered the division yet, and when he listens to these things, he naturally doesn't understand them very well.

"Well, I'll put it simply, if you want to type these numbers with rules, you must first understand the laws in these numbers, and master the laws proficiently, and then you can use them. After learning mathematics, it is to see who has more laws and rules, who is more powerful. If you have mastered the rules, even if you casually type a number 1 or a number 2, you can destroy a hill and fill a pond of water, which is not difficult. ”

"Of course, if you reach a higher level, you will be exposed to theorems and axioms that are more powerful than the laws, and only when you understand these theorems and axioms can you be regarded as a beginner in mathematics. The Pythagorean theorem and so on that I mentioned earlier can only be understood by high-level junior high school or high school students. Let's work hard!" Old Chen couldn't help but pat Xiao Ming, who looked a little dull.

"This ......" Xiao Ming has already stayed, just old Chen, and has already guided him on the way forward in mathematics. Xiao Ming thought that the ninety-nine multiplication table he mastered, the Gaussian Maga mystery was powerful enough, but he didn't expect that he still had such a long way to go, what numerical laws, Pythagorean theorem, axioms, etc...... I've never heard of any of this.

Of course, Xiao Ming has now seen the huge power of the law of numbers, and the law of prime numbers and composite numbers used by Shi Yan and Lu Yi made him initially realize the power of the law of numbers. But it is precisely because he has seen the power of the law of numbers that Xiao Ming is even more difficult to imagine how powerful the Pythagorean theorem, axioms and so on will be if he masters those in the future.

The battle between Shi Yan and Lu Yi continued, and some more esoteric spells appeared one after another. But Xiao Ming has no intention of watching. What Chen Lao told him just now was too great for Xiao Ming.

"Trick! Attack with primes within a hundred! Go!"

Just when Xiao Ming was a little sluggish, he suddenly heard Lu Yi in the middle of the battle, and at this moment, he burst out with a shocking roar.

Then, as soon as Xiao Ming raised his head, he saw Lu Yi's whole body figure fluttering, floating up and down in the space of three zhang around Shi Yan, and with the fluttering of his figure, a series of numbers, 2, 3, 5, 7, 11, 13, 17, 19, 21, 23, 27, 29,...... and so on, attacking Shi Yan standing in the center of the battle from all directions.

"What, a prime number attack within a hundred!"

Seeing Lu Yi's move, not only Xiao Ming opened his eyes wide, but the others also widened their eyes and opened their mouths. Even Xiao Ming inadvertently swept over, and saw a rare hint of surprise in Nangong Hong's eyes, and even Duan Tiansheng's eyes showed solemnity.

Compared with Duan Tiansheng's side, Yang but they saw that Lu Yi had the advantage, so they hugged their arms one by one and looked at Longhua's side with a smile of steady victory. Yang Dan's slightly upturned mouth let out a cold snort softly, as if he had seen their victory.

And at this moment, in the face of the prime attack from the uproar attack, Shi Yan, who was standing in the center of the battle, also had a solemn face, and his hands clenched the bloated fountain pen. He also didn't expect that Lu Yi's trick would be a prime number attack within a hundred. Prime number attack within 100, he only mastered the prime number attack within 80, and even if he could attack so many prime numbers in a row, the ancient poems in his body would not be able to support this kind of consumption.

He couldn't have imagined that Lu Yi, who had just been tied with him, could still have such a deep foundation in ancient poetry, and he could still support the release of so many prime numbers containing laws.

However, at this moment, he is no longer allowed to think about it, and the prime numbers are already about to attack in front of him.

"Defense! Decimal multiplication defense!1.1 times 0.1 times 0.1 times 0.1......" In an instant, Shi Yan's periphery went up and down, and immediately formed a spherical decimal multiplication defense, which is Shi Yan's absolute defense, using the law of decimal multiplication, multiplying one by one point by zero point one, and then using the resulting result, continue to multiply by zero point one, and then to the final result, one point will become one point zero...... With a dozen or twenty zeros, 1.00000...... 1。 As a result of such an equation, it is completely possible to form a huge circle and form a decimal defense.

"Boom Boom Boom Boom ......"

When Shi Yan had just formed a defense, Lu Yi's prime attack had already attacked him with a bang.

Suddenly, one by one, with a sufficient amount of spiritual energy, burst out with strong energy, attacking the defense in front of Shi Yan.

In the center of the battle, a colorful attack light flashed all at once.

"This stone rock's decimal defense is a bit tricky...... If it were me, I'd rather switch to the multiplication defense of fractions......" Old Chen's voice sounded again.

"What do you mean?" Chen Lao ...... "Now Xiao Ming's eyes are wide open, looking at the scene in the center of the battle, he is reluctant to look away, it is too exciting, the prime number attacks, coupled with Shi Yan's defense of the round ball, are simply too exciting." But hearing Chen Lao's words, Xiao Ming couldn't help but be curious.

"I mean, although this Shi Yan has a good understanding and a very thin heart, his round decimal defense is not very good, and in his defense, there are too many digits after the decimal point. Multiplication of decimal numbers is not the more digits the better, if these decimals are converted into fractions, the defensiveness will be greatly improved. What is rare is that after so many rounds of conversion, Shi Yan did not make a decimal point wrong. Chen Lao said.

"Uh......" Xiao Ming naturally didn't understand.

"Then, Old Chen, do you think Shi Yan can win?" Although Xiao Ming didn't understand, but listening to what Old Chen meant, Shi Yan didn't seem to have much chance of winning, and Xiao Ming couldn't help but hurry up to consult Old Chen.

"Hey...... In my opinion, if you replace the decimal multiplication defense with the fractional multiplication defense, you may win, but now, ......" Chen Lao did not finish.

"Ah......" Xiao Ming's heart was shocked, and he just wanted to ask Chen Lao how he failed.

But before he could say anything, he heard an exclamation from here:

"Shi Yan, be careful!"

"What's wrong?" Xiao Ming immediately looked at the battlefield.

At this glance, he saw that Shi Yan's circular decimal defense had already become a little elliptical under Lu Yi's prime attack, but in this case, when Lu Yi's prime attack was not finished, he used a composite number attack again. Suddenly, the composite attack and the prime attack were like the last straw that overwhelmed the camel, and Shi Yan's decimal defense was shattered in an instant.

Then a series of prime numbers were instantly imprinted on Shi Yan's fat body.

Before Shi Yan could make any defenses, the whole person had already flown upside down.
