After the fake daughter was abandoned, the villain brothers competed for favor

Liu Xing's face twitched violently, anger appeared in his eyes, then he thought of something and smiled again.

"Whatever you say. Jiang Shixing, since you wasted three years just to recruit your little sister who is a study waste, you will never be able to compare with me."

"Ruan Qing is now my student. With her talent, it won't be long before she can help me break through the current bottleneck and go further in research."

Jiang Shixing didn't even raise his eyelids a little bit: "So, you are showing off to me, you have to rely on a freshman to break through your own bottleneck now?"

The corner of Liu Xing's mouth twitched fiercely again!

tmd!

When he breaks through the bottleneck and becomes No. 1 in the country's mathematics field, he must ridicule this damn Jiang Shixing so much that he can't hold his head up!

Jiang Shixing watched Liu Xing leave coldly, and after a while, he sighed wearily.

Although he despises Liu Xing's actions, in fact, he is currently facing the same predicament as Liu Xing.

In fact, this is a common problem faced by all top researchers...

My own research has reached the peak of the current level. If I can't find a new breakthrough or idea, I will only be stuck here in this life, and it will be difficult to move forward!

The thesis that Jiang Shixing is currently preparing was originally prepared for publication in the top journal "sua" in the mathematics world. In the end, he prepared for three years, but he couldn't write any more because he couldn't find a new idea...

Thinking of this, Jiang Shixing couldn't help but sigh wistfully: "I don't know if I will be lucky enough to meet someone who gives me new ideas..."

"Second Brother!" A sweet and clear voice sounded at the door.

Jiang Shixing withdrew his thoughts, turned his head to look, and saw a sweet-looking girl standing at the door, smiling and waving at him: "I'm Ruan Yao, I'm here to find you~"

This is his sister who was just recognized?

Jiang Shixing had a flash of surprise in his heart.

Before, he heard from his elder brother that this younger sister grew up in a small household, didn't study well, and her academic performance was a mess, so she actually had a bad impression of her in his heart.

Although out of family friendship...and to prevent the Jiang family from being ashamed of having a junior college diploma, he exchanged an admission notice for the younger sister on the condition that he would pay the principal three years of free labor for three years, but he didn't feel sorry for her in his heart. A little bit of anticipation and love.

But now looking at Ruan Yao, who is graceful, clean and bright, Jiang Shixing felt a faint liking in his heart.

He pressed his worries to the bottom of his heart and said to her, "Come in."

Ruan Yao pushed open the door and walked in.

The first thing she saw were various calculation formulas plastered on the entire wall...

So strong!

The second brother must be immersed in the ocean of mathematics for 24 hours... Ruan Yao thought admiringly, taking a panoramic view of the entire office.

The not-so-big office was organized by the second brother in an orderly manner. On the large desk, there were no extra things except rulers, pencils, computers and other tools.

There was a pot of green plants by the window, but the leaves were already a little weary, obviously it hadn't been taken care of for a long time.

"Second brother!" Ruan Yao obediently walked to the man with a cold and arrogant expression, reached out to take out the bag, and handed over the gift she had prepared urgently with both hands.

"This is a gift I specially prepared for my second brother. It contains various mathematical formulas and ideas I have learned. I hope my second brother will like it."

Jiang Shixing's eyes fell on the blue book in Ruan Yao's hand.

It's a very ordinary notepad that costs one yuan a copy.

"You have a heart." Jiang Shixing didn't think that Ruan Yao could learn anything useful to him, and after taking it, he wanted to put it on the table.

As a result, in the next second, Ruan Yao stared at his hand with burning eyes, and her eyes almost overflowed with anticipation.

Jiang Shixing's hand stopped: ...

Although it was of no use to him, it took a lot of painstaking effort and effort for my sister, a college scum, to be able to collect these.

In order not to disappoint his sister, Jiang Shixing suppressed the boredom in his heart and turned to the first page——

Np complete problem.

Um?what is this?

Jiang Shixing's eyes froze, and a cluster of flames suddenly ignited in the cold and alienated eyes.

He didn't even care about Ruan Yao who was still waiting, he got up quickly, picked up the pen on the table, and was immersed in his own thoughts in an instant.

Seeing that Jiang Shixing liked it so much, Ruan Yao breathed a sigh of relief.

In this way, the second brother should not care too much about me being an ordinary person... Seeing Jiang Shixing frowning and thinking for a long time, then turned to the second page, Ruan Yao simply moved a chair and sat down to wait for him.

After waiting for more than an hour, Jiang Shixing finished reading everything written by Ruan Yao before he let out a long breath.

He stood up from the desk, and when he turned his head to look at Ruan Yao, the coldness in his eyes was gone.

Jiang Shixing asked Ruan Yao excitedly: "Little sister, how do you know these difficult problems?"

NP complete problem, Hodge's conjecture, Poincaré's conjecture... Each of them is a mathematical problem that Jiang Shixing has never seen before, and he can't think of it at all!

Although he couldn't find a way to solve the problem at all, these problems brought new vitality to his rigid thinking and brought a breakthrough to the bottleneck that had been bothering him!

Jiang Shixing can guarantee that if any of these difficult problems are leaked out, it will be enough to cause a national...no, a global sensation!

My mother forced me to memorize it in my previous life... Ruan Yao appropriately showed the confusion and bewilderment of a scumbag, and said with some panic: "Just, I just wanted to find a special symbol in mathematics some time ago as a gift for my second brother. ..."

"Then when I was searching the Internet, I clicked on a lot of messy websites... Some of the questions in the websites made me feel very strange, so I copied them down."

Jiang Shixing took a deep look at Ruan Yao.

Of course he didn't believe her nonsense, but the younger sister gave him such a precious treasure, so there was no need for him to explore the secrets she wanted to hide.

Immediately afterwards, Jiang Shixing thought of something, and suddenly said: "The mathematical symbol problem you asked the elder brother before, is it for me?"

How did the second brother know this?

Jiang Shihan must have a big mouth, right?

Ruan Yao complained in her heart, but nodded calmly on the surface: "Yes!"

Jiang Shixing's hand holding the notebook tightened, a warm current surged in his heart, and he felt a deep apology to Ruan Yao.

No wonder the little girl didn't ask me, it turned out that she was trying to surprise me... But I deliberately ignored her because I misunderstood that she didn't trust me...

I'm really going too far... My little sister worked so hard to prepare a meeting ceremony for me, but I only care about everything...

Thinking of this, Jiang Shixing looked at Ruan Yao with more gentle eyes: "What symbol do you want to give me?"

Just because of my little sister's will, no matter what she comes up with later, I must praise her fiercely and be responsive to her requests!

Then, he saw Ruan Yao draw an ugly equilateral triangle on the notebook, and then looked at him expectantly: "Second brother, can you write a paper on every page of the thesis you are writing?" Are you inserting this symbol?"

Jiang Shixing's expression froze.
