"Since people welcome us openly", Mo Yuan said indifferently, "We should not and cannot avoid it out of politeness." ”

"Indeed," Xiaolan echoed, "besides, there is no way to avoid it. ”

"Let's go, I'll go", Mo Yuan glanced at Xiaolan, his eyes were filled with composure and excitement, and said softly, "Red ears." ”

"Huh. ”

"Professor" Mo Yuan walked forward with a seemingly heavy suitcase with his right hand, and "Student" Xiaolan followed with a small suitcase with his left hand to the left side of "Professor", and the two walked towards the waiting area where the man was.

Although the waiting area at the exit of the airport is brightly lit, the night can be clearly seen through the ceiling composed of a huge glass ceiling. Perhaps, the light surging under the horizon in the distance is being clung to the ground by the crowded buildings of the city.

In the entire waiting area, there are only a few sleepy-eyed people waiting for their lovers or best friends, and they don't need to hold up any signs. Only the neatly dressed man, holding a huge sign, looked a little abrupt. He didn't look around, for fear of missing the people waiting, but held a sign in his right hand and a paper A6-sized book in his left hand, and was reading intently with his head down.

When Mo Yuan and his party were about five meters away from the man, the man with his head down, as if he felt that someone was walking towards him, closed the book, stuffed it into the left pocket of his pants, raised his head, and saw that Mo Yuan was walking towards him, and said overjoyedly: "Is it Professor Xun?"

Mo Yuan smiled and nodded, walked up to the man and stopped, Xiaolan also stood on the side, smiling politely at the man.

"Ah, I'm really sorry, my name is Yu Deshui, I'm a big fan of yours, I've read several of your papers on machine learning many times, and I've learned a lot from my tutor that you're going to come to our school to give a talk on machine learning, I'm very excited, and I'm very presumptuous to come to the airport without your consent, and I really want to see you at the first time." The man was very excited and spoke very quickly, but his unusually low and hoarse voice made Mo Yuan and Xiaolan sound a little reluctant.

"Ah", the man remembered something, "I stayed up late last night to write a paper, and when I woke up this morning, my throat was hoarse, cough cough." ”

"Papers are not driven out, and the body is equally important. Mo Yuan said with concern.

Xiaolan was on the side, smiling and impassive, her left hand always resting on the mast of the suitcase.

"You're saying that you look exactly like you look in the photo, and you look younger. The man looked at Mo Yuan, and occasionally a little strange attention flashed in his eyes.

"Well, I'm already young", Mo Yuan was very calm, "35 years old." ”

"Yes, yes", the man nodded, "Oh, by the way, you look at me, I was so excited to see my idol that I ignored the beautiful girl next to me." ”

"Professor Xun's student, who also works as a teaching assistant, is fortunate to be with Professor Xun this time......"

"That's really lucky, it looks more like Professor Xun's assistant, it's really enviable. ”

Just as the three of them were greeting each other without saying a word, two airport staff members carried a holographic projection device and passed by them, and one of them slipped his hand, "bang", and the holographic projection device fell to the ground.

The two panicked and erected the equipment, and one of them accused: "Look at your clumsiness, take a look, see if there are obvious fall marks on the outside." ”

"Yes, yes", the other person hurriedly observed, looking and touching the surface of the device.

Suddenly, perhaps the staff touched the switch by mistake, and a beam of projection light burst out of the equipment, and in an instant, a slim flight attendant appeared in front of the three of them, "What can I do for you?"

"Professor Xun," the man said in a low and hoarse voice, looking at the hologram in front of him, "It really looks like a real person." ”

"Oh, it's a lot like a real person. ”
