Are you the devil?

Give a fantasy world, which is equivalent to the ancients to do quadratic functions.

This operation, Sao, too Sao.

Also, it's obviously the host's own scum, but she says as if she is bullying people when she does it with others.

It's so blind that its eyes are not red and its heart is not beating, and it is still justified, it is clumsy.

Wear!

Jiusha and the others didn't know, thinking that it really meant this.

After all, the opponent's weapon is not ordinary, and if you can have such a weapon, your own strength will be low?

No way.

And obviously has this strength, but is not arrogant, and is so kind, it is too rare.

So, by mistake, I gained a lot of goodwill at the beginning.

It's just that.

Looking at the black letters on the white paper in front of me, no, it's numbers and I don't know... symbol, Jiusha's expressionless face became even more blank.

What is a parabola? Why is 2 on the top right of an object, and what are the symbols?

Qu Fuhua was also curious about the question he said at the beginning, and when he saw that Jiusha's face was wrong, he leaned over to take a look.

？？？

"What is this?"

I don't think I've ever seen it before.

"This is a quadratic function in junior high school, which is very simple, which is to find the vertices of Y. Although she didn't either, she smiled at first.

Qu Fuhua learned with some difficulty: "Crooked?"

What is crooked?

"Yes, in my case, smart elementary school students do. ”

At the beginning, he said with a sincere face, as if he was very unimpressed, and the two people who were originally tense looked at each other and were confused.

Although they didn't understand it, they probably understood.

This thing should be a child in her place.

In other words, people of such a big age still can't understand it.

“...”

At the beginning, he knocked on the paper with the finch feather, and encouraged him: "Handsome guy, come, do it, it's really simple." ”

Jiusha: "..."

Qu Fuhua looked at the silent opponent, and suddenly, he felt a little sympathetic to the other party.

Although he suffered an internal injury, it would still hurt, but in comparison, the other party was even worse.

The people under the ring were also very curious to see their reactions, and poked their heads into the stands.

I want to know what it is, why the senior brother and the reckless man of the Ling Xiao faction are like that.

Unfortunately, the neck is almost stretched out of the giraffe, and I can't see anything.

Then they turned to the head of the house standing in the middle.

It's going to stop, it looks like it's not going to fight, it's time to withdraw the barrier, let them go up and have a look.

The head didn't pay attention to the eyes of the disciples, grabbed the sides of his clothes with both hands, and looked at the stage with a serious face.

Think about how to keep this man.

Not to mention anything that oppresses people with power, they Tianji Sect can't do it, and even if they do, the other party's strength is unpredictable, and they are afraid that they can't suppress it at all.

And her character... It feels equally unpredictable, but you can't accidentally mess with her.

Be careful.

The head frowned, and at first he had already stretched out the demon's claws.

"Now, since you can't do this question, you will lose our agreement, go down, go down. ”

Quickly push people down the ring, without giving people a chance to react.

Jiusha was stunned and took the paper and stepped off the ring.

Chu Shi clapped his hands, "The first question is solved." ”

'System, fast, points to come. ’

The system that watched the whole time: '... Host, is it okay to have an ancient man do a quadratic function?'

At first: 'Okay. ’

Not only did she think it was okay, but she also had deep thoughts in her heart (* ̄) ̄)

‘... Doesn't conscience hurt?'

At first, the eyebrows and eyes are raised.
