This level of attack immediately moved Qian Qingyu and Principal Long, their Adam's apple couldn't help but move, and they swallowed their saliva with difficulty, and then the two glanced at each other, and they both saw the solemnity in their eyes. Retreat, now the strength of the two, although the speed of lightning is fast, but the two are still barely able to retreat, but after retreating, behind them is the county seat of Longhua County, they can avoid this attack, but this attack, if it hits the ground directly, the casualties on the ground will be a pain they can't bear.

Therefore, Qian Qingxuan and Principal Long only had time to glance at each other, and then both of them saw a hint of determination from the solemnity of each other's eyes.

After a moment of eye contact, the two turned back almost at the same time, looking at the lightning-like approaching powerful attack, and a red certificate appeared in their hands almost at the same time.

"Second Prize Certificate of the National Mathematics Competition!"

"First Prize Certificate of Xincheng Cup New Concept Essay Competition!"

The two unfolded the award certificate in their hands at the same time, accompanied by the red light in the hands of the two, almost instantly, the certificate in their hands just left their hands, and it was instantly opened, and then under the urging of the powerful spiritual power of the two, the two certificates of honor were like the strongest shields, blocking in front of the two, exuding a strong aura of honor, as soon as this breath came out, others immediately felt a supreme honor.

This is the breath of honor, this certificate contains supreme honor, Liu Gang attacked with honor, and Principal Long and Qian Qingfu fought back with honor at the same time.

At this moment, Qian Qingfu and Principal Long exchanged eyes, then took out the certificate and opened the certificate, but in a short breath, I saw that the certificates of the two had just opened, and Liu Gang's lightning attack was just right to impact, and then in the face of the attack that dared to block in front of it, the lightning dragon let out a loud roar again, and crashed directly into the two certificates of honor in front of it.

"Whoa!"

Like lightning, as soon as this attack hit the two certificates, it hit the most dazzling lightning light, and this moment of light made everyone unconsciously close their eyes.

"Boom, boom!"

Then, a thunderous rumble sounded, and the two certificates, at this moment, were like the strongest shields in the world, allowing Liu Gang's attack to release a powerful energy offensive, even if he didn't take a step back, he successfully blocked this attack.

This kind of certificate can resist the certificate of the high school entrance examination and the catastrophe thunder, although Liu Gang's attack agrees to have honor and lightning power, but although it is powerful, but the two certificates are real certificates, and the catastrophe and thunder can be resisted, how can it not accept this level of attack. After a series of violent impacts, the shield formed by the two certificates did not move at all, and did not let it go at all.

In the end, Liu Gang's attack could only die down and return to calm.

When everything returned to calm, the two certificates shrank again and returned to the hands of the two, but Qian Qingfu and Principal Long saw that although the certificate carried out their mission and blocked the attack, the certificate in the certificate was destroyed, and the scorched yellow traces showed that the certificate had lost the power of honor and no longer had the power to resist the thunderstorm.

A trace of pity flashed in the eyes of the two almost at the same time, this certificate was almost exchanged for a lifetime, and now under a blow, it has lost its effectiveness. However, seeing that the city behind him was still safe and sound, Qian Qingyao's eyes returned to calm in an instant, although the certificate is rare, life is even more rare.

"Dad, this Liu Gang is really hateful, can you help Ling Yun and let him break Liu Gang's defenses and let them go outside to fight. A powerful attack returned to calm, and when Liu Gang and Qian Qingyu had not yet come to their senses, Xiao Feng on the ground saw that Ling Yun had been used by Liu Gang to use the hopscotch formation, and for a moment he thought of the treatment Xiao Yan received a few days ago, and he immediately suggested Xiao Yuanshan.

Hearing Xiao Feng's suggestion, Xiao Yuanshan immediately raised his head and saw Ling Yun struggling under the scorching of various elements of the periodic table at this moment. The potion that Liu Gang had just blessed was really lacking in virtue, originally Ling Yun was seriously injured under Liu Gang's attack, but now under the restrictions of the periodic table, Ling Yun not only had to enjoy the treatment of sitting on the ground as a prison, but also suffered from the scorching flames of various elements in the cell, this kind of torment has made Ling Yun's breath extremely disordered, and he is about to die.

Of course, even after receiving such treatment, Xiao Yuanshan still saw the perseverance and unyielding revealed in Ling Yun's eyes, which was still like a spring, and the more he resisted, the more fierce he became, he could not give in, and he would never bow his head. Such a Lingyun made Xiao Yuanshan's eyes appear with a trace of appreciation.

"Well, okay, I'll help him, this battlefield doesn't seem to be able to let go of his hands and feet, I'll help Ling Yun and let him go outside and fight. Xiao Yuanshan nodded immediately, his fingers moved slightly, and an invisible energy shot directly towards Ling Yun, instantly submerging into the formation of the periodic table that imprisoned Ling Yun, and in an instant, the various elements that were still breathing fire strongly just now, as if they had been cut off from the energy supply, slowly decreased.

As the person with the highest cultivation here now, Xiao Yuanshan has an insight into the mental state of almost everyone who is fighting, even if it is Ling Yun's mind that is hidden under the appearance and wants to fight outside, Xiao Yuanshan has an insight. Xiao Yuanshan even felt that this Ling Yun had some hidden tricks to deal with Liu Gang, but now because of the reason of the venue, Ling Yun was temporarily hidden, they had a common enemy, and now Xiao Yuanshan helped Ling Yun, that is, to help himself, so he was naturally willing to take action.

"Ah, great, thank you, Dad!" Hearing Xiao Yuanshan's words and seeing Xiao Yuanshan's actions, Xiao Feng was immediately overjoyed.

"Yo, I can't imagine that in this kind of countryside, there are still people with certificates, and they are actually the second prize in the national mathematics competition. At this moment, Xiao Feng's words had just fallen, and he hadn't had time to look at Ling Yun yet, Liu Gang in the sky looked at the certificate that Principal Long had put away, and couldn't help but cry out in surprise.

Indeed, there is nothing wrong with Liu Gang's surprise, the immortal cultivators who can participate in the national mathematics competition, and also get the ranking in the national immortal cultivators, this kind of person does not talk about his talent, just saying that he has cultivated to this point, the consumption of pills, and various course auxiliary materials, are not affordable by ordinary people, and Longhua County is a poor and remote place, there is no decent bookstore, Liu Gang can actually see Principal Long, a character who won the second prize of the National Mathematics Competition, this kind of character, very fierce, although Liu Gang is still sarcastic in speaking, but the vigilance in his heart has increased a few points。 The people who can get the ranking in the competition are all from tens of thousands of junior high school students, and this kind of person, it is common for them to kill individuals by skipping the level.

Hearing Liu Gang's sarcastic words, Principal Long's face did not change at all, and he didn't pay attention to Liu Gang, and directly put away his certificate. At the same time, when the certificate was put away, an inky black and deep fountain pen appeared in Principal Long's hand, and when Principal Long took out the fountain pen, a long-lost strong aura slowly woke up from him.

"This ......"

Liu Gang, on the other hand, his face finally changed, and feeling the breath of Principal Long, he felt like a male lion that was waking up. And this male lion is not bad in strength, and even Liu Gang feels a hint of threat.

"Principal Dragon!"

Qian Qingworm, who was next to him, felt the awakening breath of Principal Long more accurately, Principal Long was about to move, looking at the city below him, Qian Qingworm's face couldn't help but be full of worry. The reason why the two were pressed and beaten by Liu Gang was naturally because above the city, the two had scruples, and Liu Gang had no scruples. And now, Principal Long's performance is undoubtedly to throw away the scruples in his heart.

However, Qian Qingworm misunderstood, seeing Qian Qingworm's worry, Principal Long strengthened his momentum while also giving Qian Qingworm a reassuring look.

Seeing this reassuring look, Qian Qingyi's worry was immediately suppressed. Only then did he realize that Principal Long was naturally not that impulsive person.

"Liu Gang, if you do too much injustice, you will kill yourself!" The next moment, Principal Long suddenly raised his head, and his eyes burst out with a trace of ruthlessness. "Pick me up, planar Cartesian coordinates!"

Principal Long's hand suddenly raised, and a pale yellow ray shot directly from the pen in Principal Long's hand, the ray was like a golden hoop stick that could be retracted freely, suddenly appeared in the air, and then instantly became longer and shot towards Liu Gang's throat in the sky.

"Hmph, carving insect skills!" Liu Gang then snorted coldly, and easily dodged it, with this level of attack, he thought that Principal Long had something to do.

"Woohoo!"

But it didn't end at all, Principal Long's figure appeared on the other side again, and another ray shot towards Liu Gang again.

"Hmph!" Liu Gang moved when he heard the sound, and he didn't turn around at all, and directly dodged the attack of this ray.

"Is that all you ......?"

"The coordinate system is formed, the inverse proportional function, give me a map!" Liu Gang was about to say that Principal Long was so capable, but before he finished speaking, Principal Long's voice sounded again.

"What, inverse proportional function!?" At this moment, hearing Principal Long's words, Liu Gang was immediately surprised to see that Principal Long actually typed a curved function image at the other end, which was the image of the inverse proportional function, and when Liu Gang was still confused, Liu Gang suddenly felt that many lines appeared on his body at once, and he was restrained at once, and then, Liu Gang was about to break free, and a powerful pulling force actually came.

"What is this?"

The next moment, Liu Gang only felt that the sky was spinning, and when he came back to his senses again, he found that he was already outside the city, and when he looked up, in the coordinate system formed by the intersection of two rays, one horizontal and one vertical, Principal Long was putting away the function image.

With just one glance, Liu Gang directly understood that he had been tricked.

Just now, Principal Long's plane coordinate system was not a real attack at all, but a prelude to an attack, and his real attack was actually an inverse proportional function. Principal Long actually drew an inverse proportional function in the first quadrant, and then took advantage of the symmetrical nature of the inverse proportional function image and the positive proportional function image, and suddenly mapped Liu Gang's whole person directly to the third quadrant, which is now outside the city.

"Fractional equations!

However, Liu Gang didn't have time to be surprised at all, because at this moment, he was already outside the city, and Principal Long could completely let go of his scruples to attack him. At this moment, Liu Gang's ears suddenly sounded the voice of Principal Long, and when Liu Gang looked up, he already saw Principal Long, who was attacking in front of him with an incomparably mysterious fractional equation in his hand, and the attacks in Principal Long's hands had already reached his head.

"Magnetic field deflection!"

But Liu Gang is a master after all, even in the face of such a critical attack, he still reacted at the first time, and then in an instant he took a step back, and a hoof-shaped magnet immediately appeared in his hand. As soon as the magnet came out, an invisible magnetic field was immediately emitted, and Principal Long's originally straight attack was also deflected in an instant.

"Grass!

However, Liu Gang didn't have time to be happy, and at this moment, he suddenly heard a familiar and unexpected voice behind him.
