"It's okay, it doesn't matter if it's a little injury!"

Ouyang waved his hand, facing a master like Kong Liwen, any carelessness would lead to a fiasco......

So, even if you are injured, you must grit your teeth and persevere!

Ouyang shook his spirits and continued to calculate.

The bull and bear also came to Ouyang's side!

"Ouyang, such a strong opponent, you deal with it alone, isn't it too indifferent to your brothers? I'm going to fight with you too! ”

"Hey, hey, hey...... Bull and bear, I never meant to leave you alone! Ouyang smiled.

Duan Ling'er and Ji Fusheng also immediately expressed their position!

"Ouyang, although I am very weak, I will not watch my friends fight alone!"

"And me, I'm sure I can help everyone!"

Ouyang nodded: "Since that's the case, let's deal with him together!" ”

Although Duan Ling'er and Ji Fusheng had just crossed the threshold of enrollment and had just begun to calculate the equation, Ouyang knew that these two would definitely be able to play a role in the battle.

"It's up to you?"

Kong Liwen sneered, and the marbles in his hands burst out, hitting Ouyang and the others like bullets.

"Surface!"

Su Qingqing shouted, relying on differential geometric equations to create a spatial surface, so that the marbles deviated from the trajectory, so that the marbles would not attack Ouyang and the others.

However, it is a pity that Su Qingqing's calculation ability is insufficient, and he must be distracted to record Kong Liwen's algorithm rules, so the surface cannot change the trajectory of all marbles at all.

There are still a few marbles heading straight for Ouyang, Niu Xiong, Ji Fusheng, and Duan Ling'er!

"I'm not afraid of you!"

The bull and bear are tall and stand in front of everyone.

Although the power of several marbles is huge, the bull and bear still grit their teeth and calculate the gravity equation.

However, the gravity equation is not a gravitational equation after all, and it can only slightly reduce the mass of a few marbles, and the energy contained in the marbles cannot be weakened.

"Boom!" "Boom! "Knock! ”……

With a few muffled sounds, the bull and bear forcibly blocked all the marbles.

If it weren't for the strong body of the bull and bear, I am afraid that I would have worn it a long time ago......

After eating a few marbles, the corners of the bull bear's mouth spilled blood, but he was still smiling.

"Is this the strength of the teachers of Yuzhou University? That's it! ”

"You ......"

Kong Liwen was so angry with the bull and bear that he attacked again.

Ouyang immediately said: "Ling'er, lock his hands and feet!" ”

"Yes!"

Duan Ling'er understood and began to calculate.

Equilateral trigonometry equation C=3a!

After becoming a scholar, most people will choose physical and chemical equations, because the attack of physical and chemical equations is more intuitive, and the power of calculus can be immediately reflected.

However, because she saw Ouyang use the circumference equation to fight against people, Duan Ling'er also gave up the mathematical equation, but calculated the equilateral trigonometric equation, which has achieved initial results.

The reason why Ouyang's circumference equation can cause a whirlwind is because it substitutes the parameters of the surrounding gases, but this calculation method is too complicated, and it is difficult for Ouyang to succeed if it were not for the guidance of Mr. Meng Jiang.

Duan Ling'er herself, naturally, can't substitute the gas parameters into the equilateral trigonometric equation, what she can substitute is only the space itself, so the effect after the calculation is not enough for attack, but the defense is more than enough!

Under Duan Ling'er's calculations, the triangular shackles immediately locked Kong Liwen's hands and feet, making it impossible for him to move his hands and feet freely.

Since the triangle has the strongest stability of all the figures, even if it is as strong as Kong Liwen, it cannot immediately get rid of the constraints.

"Humph! Insect carving skills! ”

Restrained by Duan Ling'er, Kong Liwen didn't panic, a marble shot out, and accurately attacked Duan Ling'er's front door.

"Surface!"

Seeing this, Su Qingqing immediately built a curved surface in front of Duan Ling'er's eyes, but the trajectory of the marble suddenly changed from a straight line to a parabola, bypassing the curved surface impartially, and continuing to walk towards Duan Ling'er.

Ouyang immediately calculated the spiral equation, and a ferocious tornado headed towards the marbles that were attacking Duan Ling'er!

"Boom!"

With a loud bang, the marbles collided with the tornado and turned into powder.

Duan Ling'er escaped, but her calculations were stalled due to interference, and the triangular shackles that bound Kong Liwen's hands and feet were gone.

"I'm sorry." Duan Ling'er lowered her head.

"It's okay, that guy is too cunning, but he's already at the end of his crossbow!" Ouyang comforted.

Su Qingqing, who was standing behind Ouyang and Duan Ling'er, immediately said, "Everyone, I have already seen through his attack line, but I can't defeat him with my own strength alone!" Only the 'Cartesian array' has a chance! ”

"Good! Position! ”

Ouyang said loudly, and gathered beside Su Qingqing along with Niu Xiong, Ji Fusheng, and Duan Ling'er.

The so-called "Cartesian array" is a formation used by several scholars when fighting together, attacking the enemy in a joint force, and it is powerful.

In wars, the use of "Cartesian arrays" is quite extensive, but in recent years, the relationship between the three major powers has stabilized, and there has been no war for decades, and scholars have always been arrogant and do not like to cooperate with others, so "Cartesian arrays" are used less and less.

Ouyang and other students of Yuzhou University can only learn the basic concept of "Cartesian array" in books, but they have never used it in practice, and there are some risks in using it when facing a strong enemy like Kong Liwen.

"'Cartesian array', such an outdated thing, trying to beat me? You're naïve, aren't you? ”

Kong Liwen sneered, and attacked Ouyang and the others with sharp marbles, and at this time, Ouyang and the others all gathered together, like live targets.

When the marbles hit, Su Qingqing's eyes were quick, and he said loudly: "Ouyang, coordinates (15,20,0)!" Ling'er, coordinates (11,28,0)! Bull and bear, coordinates (41, 45, 0)! Ji Fusheng, coordinates (58,111,0)! ”

Under Su Qingqing's instructions, everyone went to their own coordinates, just avoiding Kong Liwen's marble attack.

However, Su Qingqing didn't move a minute, several marbles rushed to his face, and Su Qingqing immediately calculated the differential geometric equation!

"Cylinder!"

A pillar of air and several marbles collided together, the pillar of air and marbles disappeared at the same time, and Su Qingqing took Kong Liwen's attack.

"Huh?"

Looking at the scene in front of him, Kong Liwen was slightly stunned, the current students' understanding of the "Cartesian Array" generally only stays in the textbook, and cannot be used in actual battles at all.

But these students were able to use it freely, as if they had been rigorously trained, which made Kong Liwen sigh, what was going on?
