Downstairs of the masonry city, an Audi a8 ran smoothly along the asphalt road into the green and lush campus.

On the solid marble monument, there are six large characters in the National Defense University of Science and Technology.

As the first key construction institution of the "2110 Project" of the Chinese army, the university is under the dual leadership of the Ministry of National Defense and the Ministry of Education. It is also a deputy military-level level. It sends thousands of troops to the military and defense units every year. Talent.

Looking at the stone monument outside the window, Lu Hao’s expression on his face was quite emotional.

Here is his alma mater.

In his image, he has not returned here for a long time.

The car was parked at the gate of a faculty and staff district. From the perspective of the wall that has been lacquered and the five-storey building, the community has been in business for some years. Pushing the door down, Lu Hao looked at the man with sunglasses behind him and sighed.

"Do you still need to follow me here?"

The man with sunglasses shook his head.

"This is an instruction from a superior. You should be fine if I don't exist."

Lu Hao frowned, but did not say anything, turned and walked in the direction of the community guard room.

For more than twenty years, there has been no change here.

He still vaguely remembers that when he first went to college, he joined the astronomy society of the school with interest, and ran to the community every three minutes.

The astronomical society at that time was as unpopular as the astronomy profession.

Not only are the members poor, but even a decent event room can't apply.

For such a society that is likely to be dissolved at any time, the school will naturally not allocate too much money. After the three-minute heat faded, most of the members who had filled out the application for the hot group were gradually no longer participating in the activities. Even the minister himself was busy with other things.

There is only one exception.

Even today, Lu Hao still remembers the name of his old man.

Professor of the Astronomical Society, Professor Nie Changhai. The research direction is branching in the branch of astronomy, from the unpopular to the topic of stellar defense theory. Although it is in line with the characteristics of the National Defense University, but not to mention the professor, many students are scornful of this inexplicable subject.

No matter how people at that time viewed him and his subject, Lu Hao knew very well that his old man never took the view of others, but wholeheartedly made his subject a lifelong career.

If you have to choose an authoritative representative for the defense of extraterrestrial civilization, perhaps only he has that qualification.

Thinking about it, I walked to the guard room at the entrance of the community. Lu Hao tapped the window glass and woke up the guard who was dozing off.

"Is Professor Nie Changhai still teaching?"

"Hey, I don't call to ask the church..." I wiped the horn of the mouth, and the thick-eyed guard just wanted to blink. However, when the line of sight and Lu Hao were on the line, the momentum was suddenly pressed back, even the mouth. The swearing of Bentham also disappeared.

After being a guard for so many years, he did not practice other skills, but he only managed to understand his skills.

Broken, I am afraid that it is a leader who comes above...

The heart screamed bad things, and the guard lost a smile.

However, Lu Hao did not have a general knowledge of him, but he repeated it patiently.

"Professor Nie Changhai is still teaching?"

The doorman squatted and quickly passed the name of each professor in his mind. However, he did not remember the name Nie Changhai. I thought I was wrong, so he whispered a sentence.

"Which?"

"Professor Nie," Lu said.

The guard smiled and shook his head.

"Sorry, I have been working for more than three years. I have never heard of a professor named Nie. Or, I will call you to ask about the teaching affairs?"

"This way..." Lu Yan sighed. "No."

I want to come, too. It has been more than 20 years. Even if he is still alive, it should be a rare year.

Just as he was about to turn and leave, there was a slightly cold female voice behind him.

"You look for Professor Nie?"

Slightly squatting, Lu Hao turned and looked at the young woman behind her.

She is not old enough, and she is not an undergraduate student from the temperament. She wants to be a graduate student or a doctoral degree at the National University of Science and Technology. From her face, Lu Hao saw a few gods, but there was no mention of who the gods belonged to.

"Yes, may I ask you?"

"I am his granddaughter, Nie Han. Are you looking for Professor Nie?" said Nie Han.

"You are the granddaughter of Professor Nie?" Lu Hao's face showed a touch of joy, said with a smile, "I hope you can help me to tell the elderly, and that the student Lu Hao has something to ask for advice."

"Luo Lun?" Hearing this name, Nie Han’s voice brought a bit of warmth, no longer as indifferent as before. "The old man always mentioned your name during his lifetime and praised you for being taught in his life. The most proud student."

Lu Hao lived and looked at her incredulously.

"Before you live?"

Nie Han nodded, did not speak, but only slightly lowered his eyebrows.

The branches of the birch tree swayed gently and rustled in the wind.

Lu Hao’s throat was slightly moving, and a lot of words were flowing in the throat. Only because he could not find someone to tell, he only made a long sigh.

"is it?"

Looking at the expression on Lu's face, Nie Han was slightly intolerable, so he whispered, "Professor Nie is no longer there, but the relics in front of him are still in his study. No one has ever been moved. If you are interested I can take you to a trip."

"That will trouble you." Lu Hao nodded.

"Where, you are the hero of China." After a pause, Nie Han’s face burst into a smile, and then said, "What's more, if you can learn what you used to be, you must be under the Jiuquan. I am very pleased."

Behind Nie Han, Lu Hao took the bodyguard behind him and walked deep into the faculty community.

Passing through the tree-lined road and stepping on the cement-grey stairs, Nie Han took out the key, pushed open the security door, and walked inside the house.

"It's here. Since the old man left, this house has been empty. There is his study. The old man doesn't like other people to confuse him, so we keep the room as it is, only in each At the end of the month, it will be cleaned once.” When it comes to this, Nie Han’s face is apologetic. “I was prepared to clean it today. The result is not yet available. Now the ash inside may be a bit big, or you Sit in the living room for a while..."

"How is this very interesting!" Lu Hao quickly waved his hand and took the broom from Nie Han's hand. He said indiscriminately, "Speaking of it, Professor Nie has passed away for so long. I learned this as a student until today. The news didn't even sweep the tomb for him. This cleaning, let me come."

"How is this going, you are a guest..."

"What guest! I am his student!"

In the end, Nie Han did not live with Lu Hao’s insistence and had to agree to his request.

I saw Lu Hao holding the broom and the bodyguard behind him was busy, "I will help you."

"You are waiting at the door."

However, Lu Hao did not appreciate it. After leaving this sentence, he took the cleaning thing into the house.

With a sincere heart, it took half an hour, and Lu Hao swept the last trace of dust in the study.

When I saw a new study, the row of old people on the shelves saved up with the sacred treasures. He seemed to return to the summer of more than 20 years ago, only to feel that the eyes were slightly moist.

Wiping the lower corner of the eye, Lu Hao walked over to the desk and sat in the position where the teacher had been sitting.

In his impression, Professor Nie will record his thoughts on paper whenever he thinks of something, and regularly put it on a notebook he carries with him. The notebook he had seen before, but because the content is too sci-fi, so that he once regarded it as a novel without a plot.

Did not live up to his expectations, that note is still placed in the drawer on the left hand side.

Gently wiped off the dust on the cover page, and Lu Hao flipped the note directly to the last page.

"...only the universe, I can't give you any standard answers. The only thing I can do is to give you an idea and guide you to inspiration."

Whispering the familiar words, Lu Hao closed the page.

The finger gently licked the yellow cover, and he whispered to the old desk.

"Thank you."
