Professor Joseph’s pupils expanded, he looked like he just saw a ghost.

It took him several years of intense research to complete the Dixit-Stiglitz Mode with his collaborator, Dixit. He proposed the model in his thesis “Monopolistic Competition and Optimum Product Diversity”. This thesis shocked the entire economics community. This indirectly gave birth to the “New trade theory” and won him a Nobel Prize in Economics in 2001!

No one knew about mathematical economics more than him!

Joseph was well aware of how difficult it was to develop a mathematical model that could be used to analyze economic models…

However, Lu Zhou was now telling him that the Lu Bewley model only took him an hour?!

This is ridiculous!

Even if he used the Bewley model as a foundation, it is nearly impossible to improve this sophisticated model in an hour!

In one hour…

It would take most people days just to understand the Bewley Model.

“You have to be kidding…” Professor Joseph said as he stared at the whiteboard.

He was obviously speaking to Lu Zhou.

However, his words didn’t reach Lu Zhou’s ears.

Because his words were masked by the audience’s exclaims.

And the man who was writing equations on stage…

He was long gone.

…

Outside of the lecture hall.

Lu Zhou closed the door behind him and heard a commotion behind him.

The commotion was quite loud, and he could hear it through the walls.

“Is it really so surprising?”

I’m not lying, it really only took one hour.

Lu Zhou realized that he didn’t want to stay here for any longer. He tried to walk away from the lecture hall.

However, a young lady with short black hair and who was carrying a notebook in her hand chased after him.

“God Lu! Can you be my mentor?!” the girl excitedly said while using her body to block Lu Zhou’s path.

Lu Zhou looked at the girl and spoke with a headache.

“You’re studying economics, right? I don’t know a lot about economics, you should find someone else—”

The young lady stepped forward and spoke.

“I was deeply moved by your performance on stage! You’ve opened my eyes! I-I want to study mathematics with you!”

Lu Zhou: “…?!”

What is this chick talking about…

Lu Zhou knew that more people were going to chase after him, so this was his chance to escape. He took a deep breath and spoke.

“I’m sorry, you seem like a good person.”

Lady: “???”

Lu Zhou quickly walked past her, toward the direction of the elevator.

He went for an hour run every morning, so he could easily outrun some wannabe economics student.

“Wait a second, God Lu, don’t leave!”

Lu Zhou closed the elevator door and smirked.

“Too slow.”

The elevator door closed.

The elevator began to go up.

The people in the elevator looked at each other.

What is going on?

…

Even though Lu Zhou didn’t check in at the hotel, he could access the hotel elevator using his conference invitation card.

Lu Zhou went to the executive lounge and showed the front desk his invitation card. He took a seat by the window, behind a bookshelf.

“Do you want to drink something?”

“A cup of coffee… and some paper.”

“Is A4 paper fine?”

“Sure.”

“Okay.”

The waitress turned around and walked away.

Lu Zhou took out his phone and looked at the time.

It was two o’clock in the afternoon. It would be a while before the hotel buffet would be ready.

Lu Zhou looked at his phone and muttered to himself, “Should be enough, right?”

The waitress came back with a stack of papers.

“Here’s the A4 paper you wanted, but the coffee will take a while.”

Lu Zhou nodded and said, “That’s fine, I’m not in a rush.”

He now had some paper and a pen.

Lu Zhou took out his souvenir pen from his pocket. He pondered for a while and began writing.

He actually didn’t understand the report in total just then.

Even though he had never done any research in economics, combining the information provided by Xiao Tong, as well as the content explained by Professor Joseph, he was able to obtain a rough understanding of the economics side of the Lu Bewley model.

After learning about the economics side of the Lu Bewley model, he realized that Professor Joseph wasn’t entirely incorrect.

One could make the case that Joseph was half-correct.

This type of situation was very common in applied mathematics research.

Some things were obvious for Lu Zhou, but for scholars outside of mathematics research, these things were not obvious at all.

“… Professor Krugman’s hypothesis is true, there is room for improvement on the Lu Bewley model, both in the mathematical side and the economics side.”

Lu Zhou recalled the information he heard in the report. He treated this as a mathematical modeling problem and began to write on the paper.

Soon after, a fully written A4 paper was in front of him.

Lu Zhou looked at the paper and gathered his thoughts. He gradually smiled.

“It’s not anything interesting, but since I’m already here, I might as well finish…”

…

When someone entered a state of concentration, time often passed by quickly.

Without Lu Zhou realizing, the sky began to gradually turn dark.

Lu Zhou’s phone on the table vibrated.

Xiao Ai: [Master, you have mail (๑•̀ᄇ•́) و✧]

Lu Zhou put down his pen and looked at the sky outside the window. “Is it from Professor Krugman?”

Xiao Ai: [Master, you’re correct! Good guess! (・∀・ *)]

Lu Zhou: “What did he say in the email?”

Xiao Ai: [He asked if you have time to get dinner together. ⊙▽⊙]

Lu Zhou tidied up the dozen or so A4 papers in his hand. He looked at the half-completed page, contemplated for a second, and spoke.

“Write a reply to him.

“Tell him I can do dinner at seven o’clock.”
