That son is 22 years old this year, stays in the Tang family's company, doesn't work well, and knows how to do things all day long.

The attitude towards Su's mother is also extremely poor.

Thinking of that second ancestor stepbrother, Xia Ling's brows twisted.

He put the card back in his pajamas.

*

Downstairs, Xia Ling knocked on the door and entered Tang Mohan's study.

Tang Mohan sat in front of the computer, his slender fingers flying on the keyboard, sometimes twisting his eyebrows and thinking.

Very seriously.

Xia Ling walked around and saw that on his screen, it was a black hole game of mathematical puzzles.

She seems to have heard of this kind of game, which launches a virus program on her computer and opens up one math problem after another.

If you can't solve all the problems within the specified time, the computer will be infected with a virus and completely scrapped.

And Tang Mohan probably entered the study and opened the program, and now 63 of the 100 math problems have been solved.

Knowing that he couldn't be distracted by this kind of question, Xia Ling stood aside.

watched quietly, and waited for Tang Mohan to clear the game.

She didn't make a sound, but Tang Mohan's eyebrows gradually twisted.

The girl stood next to him, and the faint fragrance of bath whey on her body, as if she was conscious, kept drilling into Tang Mohan's nose.

They all used the same shower gel, and when Tang Mohan didn't think this brand of shower gel was so fragrant and smelled so tempting......

"Su Xia, can you stay away from me." Tang Mohan quickly typed the answer in his hand, a little impetuous.

Most of these problems are high-math calculus, which requires a lot of calculations, and he cleared this game by relying on the whole process of mental arithmetic.

A slight distraction will affect the speed of answering questions.

Xia Ling didn't move: "Why?" Isn't it just a math game? It's still a secret, can't I even take a look? ”

"It's not that it can't be, it's-"

Tang Mohan raised his eyes, he wanted to tell the girl the situation straightforwardly.

However, he just raised his eyes.

The girl was wearing a gray wide T-shirt, her forehead hair was trimmed, and her beautiful face was cleanly exposed in the air.

The peach blossom eyes looked at him with doubts.

It also reflects his gaffe.

Suddenly, the girl's beautiful peach blossom eyes rolled her eyes at him.

"Tang Mohan, what are you doing? If you keep grinding it any longer, your computer will be scrapped! ”

“…… What the? Tang Mohan came back to his senses.

In front of her, the girl squeezed over, and her white hand quickly typed a number on the keyboard, and then hit the car back.

The screen flashed to show "Correct Answer".

Watching her move, Tang Mohan was completely sober.

The bottom of the boy's clear eyes gradually became deep.

Is one answer a coincidence, two answers, or a coincidence......

The third, the fourth......

The last 30 questions, quickly solved under the girl's hands, look at the speed of this mental arithmetic, the girl solves the problem, the mental arithmetic ability is a little stronger than him?

Among other things, these questions, involving calculus, are already the difficulty of advanced mathematics in college.

When Tang Mohan is usually a little annoyed, he likes to use these topics to exercise his thinking and calm his emotions.

But he never expected that the hiding of the girl in front of him would be deeper than him!

To be so proficient in advanced mathematics, such mental arithmetic ability.

How did she do it, in the opening exam, she only scored more than 30 points in mathematics?
