The appearance of the ancient *little stupid bear* Daisy's teeth and claws amused Lu Linxi, and she rarely quipped: "Your mind is too easy to guess, wear it well, I will be angry if you can't see it." ”

Gu Daisy snorted proudly, saying that she was disgusted, but she still obediently hung the jade ornament around her neck.

The jade ornament is the appearance of a cute little bear, and it can barely be counted in her eyes.

"Hmph."

"Goodbye, I wish you more and more wisdom."

How can anyone wish people to get smarter and smarter?!

Lu Linxi is bullying her!

Boom......

“…… Bah! Scumbag! ”

Dropping this sentence, Gu Daisy ran away like a gust of wind.

As soon as she ran into her yard, Gu Daisy felt that the necklace on her chest was heating up, different from the scorching iron at the beginning, this heat was more mild, making people feel comfortable all over, I must say, it was like being in her mother's belly.

It was so comfortable that she wanted to moan, moan and sigh!

Immediately afterward, a terrifying heat burst from the back of her neck, extremely sharp and violent.

After the shock, it was as if something had left her!

This Duxi's sudden withdrawal made Gu Daisy suddenly trance, and almost fell down the stairs, but she had to stabilize her body in time, otherwise she would have broken her head and bleed.

When the dizziness passed, the world in front of me seemed to be clear in an instant!

The sky is getting higher and farther, the field of vision is getting wider and wider, her thinking is becoming more and more active, and countless thoughts and thoughts are crazily stuffed into her mind, scene by scene, one by one, piece by piece...... Almost crushed her soul!

She gritted her teeth to bear it, not letting herself let out a little cry of pain, and held the necklace that Lu Linxi gave her with one hand.

It seems to be able to bring infinite power to yourself!

Bear with me!

Bear with me......

……

When Gu Daisy woke up from the earth-shaking and reborn dizziness, she was startled when she found Lu Linxi next to her: "You...... What are you doing?! ”

"Awake?"

"Huh? Well. ”

Lu Linxi decisively took out his little magic weapon: "I did this." ”

Gu Daisy looked suspicious and almost fainted on the spot.

The magic weapon of fart!

This is a terrifying sword that kills people invisibly!!

Lu Linxi actually gave her a number! Learn! Ask! Answer! Title!

And it is not an ordinary question and answer, but a mathematical question and answer related to matrix operations!!

In the problem, the nth-order square matrix is given, and n row vectors are extracted from it, and the problem defines two operations, one is the product of the common corresponding elements, and the other is suspected to be the vector product. With such a difficult question, she will be a ball! （1）

Gu Daisy's brain suddenly hurt, and she gritted her teeth and said, "Are you going to humiliate me?" ”

Lu Linxi smiled: "Don't give it a try? I chose it for you. ”

Gu Daisy: "...... "Then I really thank you!" "How could I!"

Lu Linxi pushed the topic forward: "Give it a try, what if?" ”

Her eyes are very calm and peaceful, like a pool of clear lake water, surrounded by Gu Daisy, who was really comforted and began to solve the problem without taking any effort!!

Time passed slowly, and when Gu Daisy sat up, the bones all over her body "rattled", like rotten wood.

But her soul was sublimated!!

Thorough sublimation!!

She, Gu Daisy, known as the little waste wood of research, the first stupid person in the Gu family, actually solved this perverted matrix operation problem!!

Bahahahaha!!
