[If you're willing to wait until seven o 'clock, I'll go.] (? ∠) _]
Professor Krugman opened his phone and looked at the email again. Even though he didn't quite understand what the emojis meant, he could still understand the first line of text.
"Five minutes, seven o 'clock." Professor Angus looked at his watch and said, "Are you sure he said seven o' clock at night?"
Professor Krugman had a bitter smile on his face. He shook his head.
"To be honest, I'm not sure, I'm not even sure if he meant today or tomorrow."
"You should ask!"
Professor Angus sighed and stood up. He continued to speak.
"I'll go get something to eat … I can't wait forever. I suggest you go get something to eat too, dinner is in an hour, and it's not healthy to eat before going to bed. "
Just as Professor Angus picked up his plate and was about to go get his food, a figure suddenly walked over from the direction of the door.
The moment Professor Krugman saw the face that left a deep impression on him, his eyes lit up … He stood up with his hands on the table and enthusiastically reached out his right hand to greet Lu Zhou.
"Haha, welcome! Professor Lu Zhou, nice to meet you! "
When Professor Angus saw Lu Zhou in the cafeteria, he put down his plate with a smile and walked up to Lu Zhou.
"You're finally here!"
"I'm not late, right?" Lu Zhou looked at the silver watch on his left hand and muttered to himself, "That was close, one minute away from being late."
Professor Krugman patted Lu Zhou on the shoulder and said, "Don't worry about that one minute, we're willing to wait for you. Let's talk while we eat, I'm starving."
Lu Zhou said, "You guys haven't eaten yet?"
Professor Angus said matter-of-factly, "Aren't we waiting for you?"
Lu Zhou's expression was slightly embarrassed as he coughed lightly.
"… Actually, you can eat while you wait. I don't really mind."
Professor Krugman and Professor Angus fell into silence. They looked at each other in silence.
His expression seemed to be saying …
MMP！
Why didn't you say so earlier?!
…
The three of them came back with their meals and sat at a table for four by the window.
Professor Krugman looked at the empty seat next to Lu Zhou and suddenly remembered something. He took out his phone from his pocket.
"Let me make a phone call first."
Lu Zhou nodded. He was already starving, so he didn't bother being polite with the two people sitting opposite him. He reached for his knife and fork and began to cut up the Boston lobster on his plate.
After a while, Professor Krugman, who was on the phone, came back.
Coming with him was Lu Zhou's sister, Xiao Tong, who flew to Princeton a few days ago …
"Hey … Bro."
Xiao Tong waved his hand awkwardly and sat next to Lu Zhou.
Lu Zhou wasn't surprised to see his sister sitting next to him. He just smiled and spoke.
He smiled and said, "How are you? Are you adapting to the new environment? "
"Pretty good …" Scratching the back of his head in embarrassment, Xiao Tong whispered, "Aren't you surprised? I'm in Shanghai. "
When Lu Zhou heard Xiao Tong's question, he smirked.
"Professor Krugman is here, so I guessed he would bring you here. Let me guess, when the plane landed here, did he ask you to call me? Did he ask you to call me? "
When Xiao Tong heard Lu Zhou's perfect description of what happened the day before yesterday, she blinked in surprise.
"Huh? You guessed it? "
"Wait a second, you didn't call her?!" Krugman looked at Xiao Tong, then at Lu Zhou. He awkwardly coughed and said, "Let me make it clear, I didn't ask her to call you, I just wanted her to call her family to let them know you're safe."
Lu Zhou: "What's the difference?"
"Okay then." Krugman shrugged and leaned back in his chair. He said helplessly, "I apologize, I was a little smart, but I swear I didn't mean any harm."
Professor Angus, who was sitting next to Professor Krugman, said, "Krugman was just being nice. He wanted you to see his research results shine in this field, so he wanted you to come here … Actually, I'm sure you've seen it, the Lu Bewley model is one of the most popular fields in economics. I wouldn't be surprised if the Nobel Prize Committee gave you an award.
"It's too early to say this, they still owe me a physics prize for the theory of the strong electric interaction. They should at least give me that thing first."
Lu Zhou smiled nonchalantly. He turned his gaze to Xiao Tong, who was a little nervous, and spoke.
"You're already in Shanghai, why didn't you call me?"
Xiao Tong pursed his lips and sighed in the end.
"Okay then, I'll be honest … I was afraid you'd laugh at me."
"If you really told me the truth, you wouldn't have said such things to fool me."
Lu Zhou looked at Xiao Tong and spoke.
"Actually, you don't have to worry about me at all."
The moment she heard this, Xiao Tong's eyes widened slightly.
"Why … are you talking about this?"
That surprised voice carried a trace of astonishment and astonishment from being seen through. His eyes flickered with surprise, as if he had not expected this at all.
It was like he had done something bad behind the back of his parents, only to be seen through as soon as he got home.
"Because that's what you're thinking about, right?"
Lu Zhou smiled and shook his head. He sighed and spoke.
"Actually, it's quite troublesome for me to be asked by others. There are a lot of things that I can't refuse because of my responsibility. Including coming to Shanghai and participating in the ILHCRC unveiling ceremony, these are all quite troublesome for me … "
Actually, he had always been able to feel the contradiction in Xiao Tong's heart.
On the one hand, she wanted to rely on him, but on the other hand, she longed to get rid of her dependence on him. She longed to change from the little girl who was bullied at school to a strong, independent, and even powerful mature person like her brother …
After living together for so many years, he knew her too well.
After all, this little girl had been following him ever since she started wearing diapers. Their personalities were almost carved from the same mold …
Lu Zhou paused for a moment. He looked into Xiao Tong's eyes and spoke.
"… But you're my sister, you're not someone else. No matter how many times you ask me, I've never considered your matters a problem. "
Her eyes widened slightly, and a layer of mist gradually appeared on them.
"… Brother."
Lu Zhou smiled at Xiao Tong. He reached out and rubbed the little girl's head hard.
"Don't hide anything from me in the future! Do you still remember what I said to you during the New Year when you first started your undergraduate studies? "
Xiao Tong wiped the corner of her eyes with her sleeves and sniffled. Her voice was choked with emotion.
"… Which one? You talk so much, how can I remember? "
"I'll help you show off and fly." Lu Zhou smiled and joked, "I'll also win a Nobel Prize in Mathematics."
The first half of the conversation was in Mandarin, but the last half was in English.
Professor Angus was confused. When he heard this, he suddenly complained, "There's no Nobel Prize in Mathematics, it's an Economics Prize!"
"That's right! I agree with Professor Angus, "said Professor Krugman, who was sitting next to him. He nodded seriously and said," Of course, even though there's no Nobel Prize in Mathematics, that doesn't prevent mathematicians from winning … If you continue to research the Lu Bewley model, you'll win sooner or later. "
"Haha, don't get too excited, you guys are right, there's no Nobel Prize in Mathematics. That's an honor for economists … I'm just kidding."
Lu Zhou smiled and looked at Xiao Tong. He had a serious look on his face as he spoke.
"Regarding the report in the afternoon, I thought about it for a long time after I left the lecture hall.
"Even an outstanding scholar like Joseph, who is good at using mathematical tools, would have such a major misunderstanding. Perhaps there is something wrong with me."
"This time, I was a little more serious. I made some simple improvements to the Lu Bewley model." Lu Zhou took out a stack of A4 papers from his pocket and looked at it. He then handed it to Xiao Tong and said, "The things on these draft papers are the improved Lu Bewley model.
"Even though I'm not sure if it's as effective as you guys described, at least in a mathematical sense, it's more rigorous and more operable than the previous model."
After that, he squinted his eyebrows and looked at Xiao Tong, who was holding a stack of A4 papers in her hand, in front of Professor Krugman and Professor Angus.
"This time, I didn't just use an hour."
