Professor Gu Liang's home is on the edge of the Aviation College on Xueyuan Road, and the three-story red building looks taller than the four-story building. Gu Guoqiang touched the pocket of the suit, and the floppy disk he took from Fei Meng's house quietly poured into the inner pocket, he pulled Chen Fangyu's hand, and the sweat in his palm made Chen Fangyu's hand shrink back involuntarily.

"Why are you so nervous?" Fang Yu grabbed his arm and said.

"Can you not be nervous, if you are big, this is called theft of state secrets, and if you are small, this is called embezzlement of public property, do you think I can not be nervous", Gu Guoqiang muttered in a low voice, clamped Chen Fangyu's hand, and said, "You haven't been here, you must call Professor Gu Liang when you meet for a while, don't call Professor Gu, Gu Liang is a compound surname, and the professor's full name is Gu Liangfeng, I was wrong the first time, and that kid of Fermont deliberately didn't tell me, causing me to lose face."

The one who opened the door was Aunt Li of Professor Gu Liang's family, it is said that she is a distant relative of the professor's wife, Aunt Li is almost sixty years old, and there is no gray hair on her head, which always makes Gu Guoqiang very envious, because his father is about the same age, but his hair is gray.

As soon as he sat in the living room on the first floor, Gu Guoqiang began to lie restlessly, "Aunt Li, is the master at home?" ”

"Not at home".

"Aunt Li, can I use the bathroom on the second floor, Fangyu wants to use the first floor, can anyone use it on the second floor?"

"It works, no one uses it now," Aunt Li's words came faintly from the kitchen next door.

Gu Guoqiang walked up the stairs quickly to the second floor, here is the professor's entertainment and rest place, the bar, billiards, fitness equipment, home theater everything, the bedroom and the studio on the third floor are not allowed to go up, it is estimated that the professor is on the third floor, about to come down. Gu Guoqiang went straight to a small table next to the bar with light hands and feet, listened to the stairs on the third floor with his ears pricked up, quickly found the small wooden door that Fei Meng said, opened the wooden door, and took out a laptop from inside.

At that time, laptops were a rarity at all, and they were all black and white LCD screens, and Gu Guoqiang had only seen them from the Taiwanese in their advertising agency, although this thing was not too light at that time, but it still made him envious for a while.

Gu Guoqiang returned to the living room, and Professor Gu Liang came down from the third floor after a while.

To say that Gu Guoqiang is also a well-informed person, but every time I see Professor Gu Liang, he is very restrained, the professor is actually very easy-going, it is that temperament that makes Gu Guoqiang always like a child bathed in the long-lost sun, in addition to the awe of the sun, is the sense of longing for the sun in winter. Chen Fangyu next to her was also standing there woodenly, she had never seen such a spirited old man, his eyes were shining, and he was dressed in neat and elegant casual clothes, with an extraordinary charm.

Gu Guoqiang hurriedly introduced to Chen Fangyu and said: "This is Fei Meng's mentor, Professor Gu Liang."

"This is my lover, Chen Fangyu."

After a few words of greeting, Professor Gu Liang asked about Fei Meng's situation again: "Fei Meng still has no news, is there any clue from the Public Security Bureau?" ”。

Gu Guoqiang answered the professor's question while thinking about how to ask for those books, in fact, Feimeng had taught him how to say it before he came, but he didn't know if the professor would believe it, and he was also worried about whether the disk was working.

"Professor, that's the case, you know, Fei Meng's popularity is good, he is also very happy to make friends, classmates are closer, two days ago I went to his house, to visit his parents, his mother said that Fei Meng has a classmate named Shen Qinghua in the United States is very anxious to find him, now the domestic network, e-mail is not developed, write a letter and did not see a response, so I called, said that I was in a hurry to find some information, a few books, Fei Meng's mother told Shen Qinghua Fei Meng, Shen Qinghua said to think of another way, But Feimeng's mother was afraid that Feimeng would complain that she would not help his friend when he came back, so she agreed to help him find it, and entrusted this matter to me, you see, I am not studying physics, and I didn't find these books in the bookstore, can you help? ”

Professor Gu Liang said: "Oh, Shen Qinghua, I know this name, he used to go to my lectures often, went to the United States? What are the books? ”

Gu Guoqiang hurriedly handed over the list he had copied and printed, and handed it over with both hands.

The professor looked at the list: "This, this Shen Qinghua I remember that the main focus is astrophysics, how can I ask for a book on quantum physics, and they are all high-level research papers, these are not easy to find in the United States, although they are not classified documents, but can they be useful to him?" ”

Gu Guoqiang hurriedly moved out a set of words that Feimeng taught him: "Yes, I read the letter he wrote to Feimeng, and he said this: He said that macrophysics and microphysics have always been in almost two different research fields, macroscopic physics mainly starts from the study of gravity, and microphysics mainly studies motion, and his mentor in the United States is trying to carry out theoretical research that is common to the two, so he wants to increase some knowledge of quantum physics." I'm a layman, that's probably what it means, you see......"

"Oh, that's the case, I know about this, but I didn't expect Shen Qinghua to also study on this", the professor relaxed his puzzled brows, "You wait, I'll look for it and see if I have any bookshelf." ”

When the professor went upstairs to look for the book, Gu Guoqiang saw that the time was enough, Fei Meng said that it only took about 10 minutes, and his self-compiled program should be able to find the information he wanted and download it completely, while the professor went to the third floor, Chen Fangyu went to the kitchen to accompany Aunt Li to "chat", Gu Guoqiang quickly went to the "bathroom" on the second floor, pulled out the floppy disk, hid it in his pocket, closed the laptop and put it back in place, and quickly returned downstairs.

After a while, the professor came down from the upper floor again, and with a few books in his hand, he said, "These materials are very valuable, and I can only lend them to him for three months, and you must send them back to me in January of next year." ”

"No problem", Gu Guoqiang took the book, and said a few words of comfort to the professor that he believed that Fei Meng would return safely soon, and said goodbye to Professor Gu Liang.

Walking to the side of the wide road, Gu Guoqiang let go of the hand holding Fang Yu, lifted the collar of his shirt vigorously, let the sweat on his body breathe, and muttered: "Alas, the task has been completed, and I am so nervous." Chen Fangyu beckoned to stop a taxi, and the two got into the car and went home.
