She's a blind typing in the truest sense of the word.

It's impossible for even the best programmer not to look at the keyboard, but she hasn't looked at it once, or even missed it, in her observation time.

Sun Tong felt incredible.

A light leaked out as her eyes moved slightly.

I didn't expect Li Yan to have this hand......

So what is she doing?

Sun Tong leaned over, his neck stretched out, like a giraffe.

It didn't last a few times before her eyes hurt and her neck was sore.

She didn't know how to wronged herself, so she simply dragged a chair and sat over.

Li Yanmu does not squint.

Her side face is against the sky, her jawline is very exquisite, and when she does things seriously, she can show the charm of this appearance and temperament to the fullest.

Sun Tong shook his head slightly.

In fact, just by looking at his face, Li Yan's capital is enough to stand by the master's side.

But they don't just look at their faces.

Not to mention that Li Yan's positioning is above the hostess.

Where is the hostess so good?

If she was just a little lover, they wouldn't be so opposed and excited.

But she wasn't.

Since she is not, then she has to show the strength that a hostess should have, otherwise why should she serve the public??

If you want to wear a crown, you must bear its weight!!

Sun Tong's eyes fell on the computer screen, and he finally saw what Li Yan was writing.

She unconsciously read it out as she watched it, "P=NP complete problem solution proof?!" The more she thought about it, the more surprised she became, and she suddenly looked at the face of the person who was focused, and was stunned.

Is this pretend, really fake?

Sun Tong looked down, at first she could still understand, but soon she was in a cold sweat, and in the next step, she was no different from reading a book from heaven, obscure and strenuous to the extreme.

This...... What is it......

Her heart was suddenly withdrawn, Sun Tong didn't dare to look at it anymore, she exhaled a rough mouthful of it urgentlyTurbid gas.

Looking at Li Yan's eyes again, his eyes changed a little more.

This guy ......

The thick black eyeliner lined Sun Tong's eyes deeper and deeper, and she hooked the corners of her mouth, and her heart was interesting......

……

The commotion coming out of Sun Tong's side is really not small.

The sound of the chairs was short but harsh, especially in the classroom, which was already quieter.

Of course, the concentration of Shenghanban is still very strong for this kind of thing.

But when Sun Tong mentioned the millennium question, it was as if he had opened the trigger, and everyone looked at it.

The back row suddenly became the focus.

"Sun Tong!!" Cai Lijun's voice was majestic and sharp, faintly suppressing anger.

"What are you doing?!"

Cai Lijun walked over quickly.

Sun Tong shook his sleeves and was not in a hurry, "I didn't bring textbooks or notebooks, I plan to share them with classmate Li, and classmate Li is on the red list and knows the bottom of hell, a ready-made textbook with full scores, I want to learn from classmate Li!" ”

It's a good excuse, and I can't fault it.

But when Cai Lijun found out that Li Yan was really solving the P=NP problem and had solved a lot, Sun Tong's eyes changed slightly.

One carried the person back to where he should be.

said mercilessly: "Don't go with me for this and that, ask for advice after class, people don't say anything doesn't mean they don't bother you, you can look at the blackboard if you don't have a textbook notebook!" ”

Cai Lijun stood between Li Yan and Sun Tong.

When she looked at Li Yan again, her eyes under the frames of her glasses were faintly hot, and she put her hand on Li Yan's shoulder, her fingertips trembling.

His facial expressions are still stern and solemn, and he doesn't look approachable.

"Okay, let's move on to the next one—"
