The "Cartesian array" is not suitable for beginners.

During the war years, an army of scholars had to undergo hard training before they could kill the enemy with a "Cartesian array".

The reason for this is that the commander of the "Cartesian array" will be hard to find!

The commander of the "Cartesian Array" is the eye of the whole array, and he has a heavy responsibility, and his words and deeds determine the life and death of countless scholars in the array, so only scholars who are quite familiar with the "Cartesian coordinate system" can serve as the commander.

In the entire Chinese Federation, the scholars of the Su family who are most familiar with the "Cartesian coordinate system" are undoubtedly the scholars of the Su family, who are the best at differential geometric equations, so in the past wars, the scholars of the Su family have repeatedly served as the commanders of the "Cartesian number array".

As a descendant of the Su family, Su Qingqing's ability to calculate is still insufficient, but she has been exposed to it since she was a child, so she is as familiar with the "Cartesian coordinate system" as her own hands and feet, so this time, she served as the commander of the "Cartesian array", so that her companions can successfully avoid Kong Liwen's attack.

In the array, each scholar is a point, moving under the guidance of Su Qingqing, Su Qingqing is the eye of the formation, sitting at the origin of the "Cartesian coordinate system", so she can't move, even if Kong Liwen attacks her with more powerful force, she can only carry it!

"I see!"

Kong Liwen said to himself, as a teacher at Yuzhou University, he had also taught students the basic knowledge of "Cartesian Array", and naturally knew that Su Qingqing at this time was the eye of the whole array, as long as Su Qingqing was restrained, the number of arrays would naturally be self-defeating.

Several marbles paddled all kinds of trajectories, heading towards Su Qingqing, the marbles crossed the air, and even burst out sparks, which were much stronger than the power of bullets!

"Qingqing!"

Duan Ling'er screamed in worry, but Ouyang gritted her teeth.

"Don't move, Qingqing can handle it."

In fact, Ouyang cared more about Su Qingqing than everyone else, but he couldn't be distracted.

All of them are in the "Cartesian Array", and their every move is related to the outcome of the battle, including Su Qingqing.

Su Qingqing herself knew this very well, and could only remain motionless......

Kong Liwen's attack this time seemed to put him to death, and before the marbles arrived, Su Qingqing's cheeks ached.

Su Qingqing stubbornly calculated!

"Surface! Cylinder! ”

Around Su Qingqing, several curved surfaces were constructed, and behind the several curved surfaces, there were several air columns!

This is the strongest defense that Su Qingqing can show, and the marbles shot by Kong Liwen all hit Su Qingqing's defense!

"Boom ......"

A violent explosion rang out, and the smoke from the explosion obscured the eyes, and the crowd had no way of knowing what was happening.

It took a long time for the smoke to dissipate.

Su Qingqing was still standing in place, motionless, but her skirt was already stained with blood and had been injured by the explosion.

However, even so, Su Qingqing still gritted her teeth and raised her lips slightly......

"Ouyang, coordinates (31,18,0)! Ling'er, coordinates (22,55,0)! Bull and bear, coordinates (41, 49, 0)! Ji Fusheng, coordinates (68,131,0)! ”

This is an instruction issued by Su Qingqing enduringly, and everyone naturally understands it, and moves according to Su Qingqing's requirements, approaching Kong Liwen step by step!

"Don't underestimate me!"

Kong Liwen shouted, how can a dignified teacher be defeated by a group of students?

From Kong Liwen's hands, the sharp marbles attacked Ouyang and the others, and the momentum was violent, but Ouyang and the others had Su Qingqing's guidance, so they naturally would not be afraid of Kong Liwen's attack!

"Ouyang, (37,27,0)! Ling'er, (33,66,0)! Bull and bear, coordinates (45, 55, 0)! Ji Fusheng, coordinates (75,151,0)! ”

Su Qingqing said again, and everyone immediately moved according to Su Qingqing's order, perfectly avoiding Kong Liwen's marble's attack.

"How is that possible!?"

Kong Liwen watched this group of students move in disbelief, the equations he calculated were the most cautious, but Ouyang and the others were constantly approaching, making him gradually fall into a desperate situation!

Ouyang was the closest to Kong Liwen, and immediately cast the Archimedes spiral equation, and a fierce tornado headed towards Kong Liwen!

Due to the proximity, Kong Liwen didn't have time to dodge at all, and could only use marbles and tornadoes to hit hard!

However, as soon as the marbles were shot, the trajectory of the tornado changed, bypassing the marbles and coming straight to Kong Liwen.

This is exactly the cooperation between Ouyang and Su Qingqing, Su Qingqing used the "curved surface" to change the tornado's moving route, which made Kong Liwen unable to prevent it.

The tornado swept Kong Liwen up fiercely, tearing Kong Liwen's body like a beast, and after a few seconds, Kong Liwen's body fell heavily, and he was already covered in scaly wounds.

As a teacher at Yuzhou University, with a master's degree, Kong Liwen was so embarrassed by his students, he was naturally furious!

"Bastard! Bastard! I'm going to kill you! Kill you! ”

Kong Liwen roared angrily, he took out all the marbles, and under Kong Liwen's calculations, the marbles were like having eyes, and they went towards Ouyang, Niu Xiong, Ji Fusheng, Duan Ling'er, and Su Qingqing.

Fortunately, although Kong Liwen used all his strength to calculate, the equation he calculated did not change, so the trajectory of the marble's movement had already been expected by Su Qingqing.

“（17，15，0）！ （13，26，0）！ （25，33，0）！ （72，111，0）！ ”

When Su Qingqing was commanding, he didn't need to read his name, everyone understood and retreated to a safe area.

But there is one exception!

That's Ji Fusheng!

The place where Ji Fusheng retreated was right on the line of Kong Liwen's marble attack!

"Hey...... Kill one first! ”

Kong Liwen sneered, although he killed the most insignificant of the several people, but it was better to have one fly less than to keep buzzing in his ears.

Just when Kong Liwen thought that Ji Fusheng would definitely die, Ji Fusheng gritted his teeth and began to calculate!

Subsequently, the marbles that hit Ji Fusheng rebounded as if they had hit the mirror, and they went straight to Kong Liwen.

"What!?"

Kong Liwen was taken aback, unable to avoid it, and was shot through the stomach by his own marbles.

Ouyang saw that Kong Liwen was injured, so he naturally would not miss this opportunity, and immediately caught up with him, came to Kong Liwen's side, and then calculated the circumference equation, and a violent whirlwind swept Kong Liwen into it.

Kong Liwen has just been injured, how can he withstand such an attack?

In the whirlwind, Kong Liwen fainted and fell unconscious......
