Li Sinian heard these words when he left the bathroom.

He paused for a moment, but did not look back.

Fu Huajing walked out of the bathroom, looked around, and finally landed on Fang Chuxin, and said, "I want to see it."

Fang Chuxin pursed her lower lip, ran up to him, tilted her head, and said innocently, "Brother, your face... seems inappropriate to appear at the same time as missing my brother. If you are discovered, I'm afraid it won't happen." Easy to do."

Fu Huajing is also worried about this.

He lowered his head in despair. Fang Chuxin seemed to have thought of something, and her eyes suddenly lit up. She patted Fu Huajing on the shoulder, "Brother, wait for me. I have a way to let you in."

As he spoke, Fang Chuxin ran away.

A few minutes later, Fu Huajing saw a fox mask in her hand, which looked like one used in artistic performances. Fang Chuxin put it directly on his face and said with a smile, "This way no one will know it's you, brother."

Fu Huajing gave her a thumbs up, "Sister, you still have more evil ideas."

Fang Chuxin pursed her lips, "Brother, can you speak?"

Fu Huajing hurriedly coaxed him a few words.

By the time they arrived at the door of the classroom, Li Siannian's loud voice could be heard clearly inside the classroom.

"Who was questioning me just now?"

Two unconvinced people stood up.

Li Sinian said directly, "Professor Zhuang, can I borrow the physics question you gave me in college before?"

"The three of us will compete. If I win, then publicly apologize to me."

Everyone sitting here was stunned. Professor Zhuang narrowed his eyes, "Are you sure you want to do that question? Do you know how to do it?"

In fact, Professor Zhuang doesn’t believe it either.

No one has solved that question since it was published, and it still has an unsolvable answer. He can ask the question, but he can't solve it.

He even suspected that his question was wrong.

Lin Xiangyu was unconvinced, "It's just you? Do you still want to solve Professor Zhuang's question? I advise you not to be arrogant. We think you are a child and we are not as knowledgeable as you."

"I'm so bold today, do you dare to challenge me?"

Now that the words have come to this point, whether they agree or not, the two of them are in a dilemma.

How could Lin Xiangyu allow himself to be so provoked and humiliated? He had always been very unconvinced with Li Sichen, but he just had a good family background, started earlier than others, and even just bought the title of prodigy.

Lin Xiangyu said directly, "There is nothing I dare not do."

Since Lin Xiangyu dared, the other person naturally had nothing to fear. The three of them were all on the podium, doing the same question.

This question is really difficult. No one has solved the question asked a year ago.

After Li Siannian saw the title, he frowned slightly, and his expression seemed astonished for a moment.

Lin Xiangyu also looked sad.

It's really not easy to do, and they have been studying it for a long time.

About half an hour later, Li Siannian started to write. Because he was relatively small, he wrote while standing on the bench, so he wrote a little slowly, but every step he took was unexpected.

Professor Zhuang's eyebrows gradually furrowed as he watched. Li Siannian had completely gone off the rails.

However, this method may be feasible.

After more than ten minutes, Li Sinian finished writing all the answers.

He jumped off the chair, glanced at Lin Xiangyu and the other two, and said calmly, "Do you need me to tell you?"

Lin Xiangyu's face looked as ugly as if he had eaten Xiang. He glanced at Li Siannian's problem-solving formula and his pupils were shocked.

Yes, they all study physics, so they naturally know the principles of Li Siannian's method. Although it is a deviant approach, how can they know that it is wrong if they don't give it a try?

Simply put, Li Siannian made the right bet.

No one spoke.

Li Siannian had already started speaking, and Lin Xiangyu and Lin Xiangyu were frozen on the podium, their expressions extremely ugly.

Outside, Fang Chuxin and Fu Huajing were lying by the window looking in. Fu Huajing, wearing a fox mask on his face, was staring in, until Fang Chuxin suddenly asked him.

"Brother, can you do it?"

"I can't, I can't even understand."

Fu Huajing is very honest.

"I miss my brother so much."

Fu Huajing pursed his lips, "Then I'm not great?"

"Brother is also awesome." Fang Chuxin smiled sweetly at him.

They were talking here, and Li Siannian had finished speaking on the other side. After that, he explained the paper and said indifferently, "I don't want to hear any more public opinions about me from your mouths. I just want to have a good life." Engage in academic research.”

"Professor Zhuang, this question is to solve the problem of aircraft carriers, right? In that case, I hope you can show the demeanor that a professor should have and don't let me look down on you."

If only someone had spoken for him just now, things would not have reached this level.

No one expected that they would be taught a lesson by a little boy.

The teacher looked at Li Si Nian in surprise. When he was teaching, he didn't say any nonsense, but now he was willing to say so much in one breath... So he was completely angry just now, right?

Li Sinian glanced out the window. Fu Huajing was giving him a thumbs up. Although he couldn't see his face, it could be seen from his eyes that he was very happy.

Fang Chuxin also smiled sweetly.

Li Siannian instantly didn't want to talk to these old guys.

He put down the chalk and left the classroom.

"When do you two plan to leave?" he asked them proactively.

Fu Huajing lifted the fox mask slightly and asked him, "You really want us to leave?"

Li Sinian pursed his lips and said nothing.

Fang Chuxin knew that he had an awkward temperament, so it was not easy for him to take the initiative to ask this question. She took the initiative to hold his hand and said, "Mom is in the school doctor's office. Do you want to go over and see her?"

A trace of surprise flashed in Li Siannian's eyes.

"What is she doing in the school doctor's office?"

"Mom is a doctor, but a great doctor."

Fang Chuxin pulled him away, and Fu Huajing followed them slowly.

In the school doctor's office, Fang Tong was a little busy. After the three children arrived, she could only put them in the office. The office was quiet and no one came.

Fang Tong gave the patients on hand to other doctors. They were not serious illnesses, and she had already written medical orders.

Returning to the office, the three little guys were sitting in a row. Fu Huajing took off the mask on his face. It was rare for the three of them to be together. Fang Tong just glanced at them, and his eyes became moist.

"Siannian, if my guess is correct, you should be the elder brother, Huajing is the younger brother, and Chuxin is the younger sister."

He is the oldest child.

She asked the doctor who delivered the baby that year. The first one was sick, but they couldn't save it. Finally, someone came and said he could save the baby, so he took the baby away.
