Li Ruonan looked at the question on the paper, his brows furrowed.

looked at Chu Yun and opened his mouth as if he wanted to say something.

The woman bit her lower lip, her cheeks crimson.

The boy reacted quickly and handed over the pen with a smile.

After thinking about it, he pulled out a few pieces of calculation paper from his school bag.

"Teacher, you can check it, I continue to sell goods. ”

After that, Chu Yun walked to the stall.

Examine...

Li Ruonan smiled bitterly and sighed faintly.

This is someone who takes care of their own face.

It's a check, but it's just to make yourself wrong.

I sat down in my chair and tightened my mind and began to calculate.

The slender fingers move quickly, and the calculation process in the brain is also on the paper.

As the head teacher of the experimental class of the city's first high school, Li Ruonan's teaching ability is not strong.

In addition to the training that teachers should have, more comes from women's years of competition experience.

But after counting it twice, I didn't find anything wrong!

"Huh..."

Li Ruonan's two willow eyebrows seemed to be entwined together, and the pink fingertips became whiter and whiter.

What's going on?!

If you go through the process in your head, it should be about the same.

Li Ruonan knows the difficulty of the test points and the traps of digging pits.

But why haven't you found out?!

The woman's fair forehead already had a layer of fine sweat.

Count it again! This time it's more careful!

Li Ruonan gritted his teeth and began to calculate.

Although he was still unconvinced, he no longer asked Chu Yun to calculate.

This guy is not a normal person.

You can't learn it yourself!

Soon, the calculus paper was already densely packed.

A few minutes passed, and Li Ruonan's face was still covered with dark clouds.

She hasn't found out yet!

This piece of paper is already full of writing.

Damn it...

Li Ruonan clutched the pen tightly, and his eyelashes flickered.

Subconsciously looked up and looked at Chu Yun.

Unexpectedly, it turned out to be four eyes facing each other!

The boy is also looking at himself!

"Teacher, this question is very interesting. ”

Chu Yun stamped over with a warm smile on his face.

I picked up the calculation paper and looked at it briefly.

"We're the same! I'm almost having a problem here!"

As he spoke, the boy circled the equation with his pen.

Li Ruonan looked at it in response and put the embarrassment aside.

Huh...

Over here...

The woman's mouth opened slightly, and her pretty eyebrows furrowed.

The more I look at it, the more I feel that something is wrong!

Normally, this is just an ordinary step.

It's very easy to get in!

You don't even have to do the math!

But Chu Yun is so special to come out, now it seems...

Li Ruonan seemed to think of something, and his pupils contracted suddenly.

Copied the pen in Chu Yun's hand and began to calculate on the scroll!

Write fast!

In less than a minute, the woman's action stops!

This time I really feel hearty!

It turned out to be the wrong one just now!

Although the same answer can be drawn, this is only because the old team leader changed it well!
