All in one go, without any pauses in between.

Since the topic was too simple, Cheng Nuo solved it easily.

Then, Cheng Nuo handed over the straw paper with the complete problem-solving steps written on it to Chali, who was still dazed, turned around, and left the place with He Youjun.

After a few seconds, Chali's dull eyes gradually recovered.

Chali looked at Cheng Nuo, who only left him with a back that was fading away, and murmured, "Who is he?"

…………

At noon, He Youjun took Cheng Nuo to have lunch in the school cafeteria.

Although foreign university restaurants are more upscale than domestic ones, Cheng Nuo is really not used to such taste.

Cheng Nuo suggested to He Youjun that we should eat three meals a day at home.

He Youjun nodded and said yes!

After a few seconds of silence, Cheng Nuo asked, "By the way, can you cook?"

He Youjun looked up.

The two looked at each other silently, and consciously gave up discussing this topic.

Well, let’s eat in the school cafeteria in the future!
In the afternoon, after bidding farewell to He Youjun, Cheng Nuo came to a school building alone.

This is a laboratory just built by the school in recent years, which is currently used by professors and students of the Faculty of Science.

Professor Fresnel and several of his assistants stayed in this laboratory to work.

The third floor of the laboratory is an area for mathematics majors.Since there is no need to use large-scale professional equipment like physics and chemistry majors, it is built like a large office like a teaching building.

The scheduled meeting time is two o'clock in the afternoon.

Cheng Nuo came to the third floor of the laboratory 10 minutes early.

Professor Fresnel's office was at the entrance on the third floor. When he opened the door and walked in, Cheng Nuo saw the scene inside.

The room area is very large, at least more than 200 square meters. The structure of the entire room, at first glance, looks like a small-scale company structure.

First of all, there are more than a dozen desks, and half of the seats are occupied by people, either facing the computer, or lowering their heads, busy with something.

And in the back of the desk, which occupies about one-third of the room, is divided into two compartments, one large and one small.

Except that there is no reception at the front desk, it is no different from a small company.

There was a sound of pushing the door, and many people looked up subconsciously.

At the desk closest to the door, sat a tall white boy.

He raised his head subconsciously, and saw Cheng Nuo standing in front of him.

"Hello?" He raised his hand.

"Hello!" Cheng Nuo smiled back.

"I want to see Professor Fresnel." Cheng Nuo explained his purpose in English.

The white boy stood up and smiled slightly, "Just in time, the professor is here today, come with me!"

The white boy led Cheng Nuo, walked past the dozens of desks, received the scrutiny from five or six foreign friends, and came to the door of the large cubicle.

Boom boom boom!
The white boy knocked lightly on the door, "Teacher, someone wants to see you."

"I just thought of a good idea, but I was interrupted by you again!" There were a few muttering voices inside, and then a voice that seemed unhappy, "Okay, come in!"

The white boy shrugged, as if he was used to this, he led Cheng Nuo to the door and walked in.

It was also the first time for Cheng Nuo to see Professor Fresnel, who was famous in the world of mathematics, in real life.

Just like in the photo, he has a thin body, a dry complexion, a thick beard and long hair, and messy hair that looks like it hasn't been taken care of in months.

The clothes are still neatly worn, otherwise they would really be considered beggars if they were thrown on the street.

But his eyes were not as muddy as his age, but extremely bright, as if there was a faint flash of light.

The white boy walked up to Professor Fresnel, "Professor, this classmate wants to see you."

Professor Fresnel looked Cheng Nuo up and down.

Cheng Nuo took out a letter from his pocket and handed it to Professor Fresnel, "Professor, this is my letter of introduction."

Fresnel opened the envelope, looked down for a minute or two, then raised his head and looked at Cheng Nuo with a smile, "So it's a student sent by Huaguo."

Cheng Nuo nodded, "Yes, my name is Cheng Nuo."

Fresnel half leaned back in the chair and said in a calm tone, "I know this."

"Since you are a student sent by Huaguo, this assistant position will definitely be given to you."

"But!" Fresnel chuckled, "But you also know my temper."

He pointed to the outside of the office.

Through the single-sided perspective glass wall, you can see the five or six busy figures sitting at the desk outside.

"The few outside, as well as He Qi standing in front of you, are all my assistants. And they all came here after a series of selections."

"So, compared to them, your assistant position is too easy to get."

After hearing this, Cheng Nuo's expression didn't change at all, because these were expected long before he came.

He shrugged and smiled slightly, "So, professor, do I want to accept one of your tests to prove my strength?"

Professor Fresnel gave Cheng Nuo a sensible look, "Yes, only if you pass my test will you be qualified to sit in the office outside like them. If you fail, I will not resign from your position as assistant. Only However, I will not assign you any projects during your tenure."

Well!In this case, there is only one empty title left for my assistant position!
Apart from taking it out to pretend to be coercive, there is no use for eggs!

Cheng Nuo was very dissatisfied with Professor Fresnel's approach.But there is no way, Professor Fresnel is a super boss, and he has just barely stepped out of the new stage of Xiaomeng.

What's more, compared to Heqi's assistants who have fought through layers of fighting, he really came in through the back door.

Cheng Nuo was silent for a few seconds, then grinned, "Professor, I accept your test!"

Professor Fresnel clapped his hands, "My test is very simple, just one question."

"Please answer, are all real numbers the roots of algebraic equations?"

"Huh?" Cheng Nuo was taken aback, suspecting that Professor Fresnel was teasing him.

Does this still need proof?Simply pointless, since all real numbers r are obviously roots of the algebraic equation x - r = 0.

Cheng Nuo was puzzled.

Fortunately, Professor Fresnel then added, "Of course, there is a limitation for this question. That is, the coefficients of each term (including the constant term) can only be rational numbers."

In this way, the algebraic equations with this restriction should be called "algebraic equations over the field of rational numbers" precisely.

This is also a question that Fresnel was thinking when he was interrupted by the knock on the door just now.

Sitting in an office chair with divergent thinking, he thought of this interesting argument.In his mind, there is already a way to prove this problem.

"Professor, give me some time." Cheng Nuo said.

"Yes." Fresnel nodded, then leisurely picked up the thermos in front of him, ready to take a sip of wolfberry tea.

Suddenly, I heard a voice from the side, "Professor, I have thought about it!"

Professor Fresnel, who was hanging in mid-air with a thermos cup: "..."

Give me some time, what the hell is five seconds!
This Chinese student seems to be poisonous!
