In the scorching summer, the subtropical oceanic monsoon climate blows slowly, relieving the heat wave of the 'Beihai', a seaport city located at the southwestern tip and on the northeast shore of the Beibu Gulf.

There is no severe cold in winter, no scorching heat in summer, there are abundant marine resources, and many subtropical fruit plants are abundant, and the more famous is the silver beach composed of white and delicate 'quartz sand', it has the reputation of 'the world's first beach', many tourists from all over the world come from afar, and some people call it 'Oriental Hawaii'.

Southwest University of Aerospace Science and Technology is located in this coastal city, which is also a well-known university in China.

The scorching sun illuminates the branches and leaves of the campus in a dappled blur, the midsummer is like poetry, the youth is quiet, and the students who have gathered here are tirelessly immersed in the ocean of knowledge.

No one dared to break the peaceful and quiet atmosphere loudly, and in the largest classroom on the first floor of the teaching building, Professor Li, who was in his fifties, was giving a lecture with a pair of reading glasses.

All the students were listening attentively to his lecture and taking notes, and Professor Li's lecture was funny, humorous, and meticulous and rigorous, so that the two or three hundred students present listened quietly and attentively, without any distractions.

The topic of today's lecture is an analysis of the origin of cosmic dust.

"According to statistics, cosmic dust is the fourth largest source of dust on Earth, and these dust have a significant impact on the Earth's environment and climate. About a ton of cosmic dust enters the Earth every hour, and just one cloud of dust revolving around the Sun at a speed of 100,000 kilometers per hour brings 30 million kilograms of dust to the Earth every year, according to my personal analysis......

Just as Professor Li was cutting to the main topic, the silent class was interrupted.

"Boom! Boom! ”

There was a knock on the door outside the classroom.

"I'm sorry."

Someone spoke.

Professor Li followed the prestige, and all the students in the classroom also looked at the door, where stood two young male officers in military uniforms, at most in their early twenties, looking masculine and handsome, and majestic, which immediately made many female students in the classroom look at it and talk about it.

They looked at the professor on the podium and apologized.

"Excuse me...... Is it Professor Lee Ming-tae? ”

One of the officers was holding a folder, flipped through some of the documents inside, looked down, and then looked at the professor standing on the podium looking at them, apparently comparing the information to make sure it was correct.

Professor Li closed the book, walked to the door, and asked rhetorically, a little dazed.

"Hello, is there anything you are looking for me?"

Li Mingtai looked behind the two officers, and there were guards with loaded guns standing in the corridors outside!

One of the officers with the rank of captain saluted Professor Li with the others, and then introduced himself: "Hello, we are captains of the 41st Army, please come with us." ”

Professor Li was still confused, and asked puzzledly, "You ...... What is this for? ”

"Please come with us, we'll explain to you later on the road." The other captain pleaded mercilessly, obviously, no matter how Professor Li refused, it is estimated that they will find a way to take him away, but somehow?

Professor Li thought about it, he didn't seem to have made any mistakes, why would the army find him, besides, even if he made a mistake, it should be the police, how could it be the army?

"Professor Li, please come with us, the time is urgent, we will explain the details to you on the way." At first, the captain who was the first to speak said.

It sounded like there was really something urgent to find him, Professor Li thought about it, nodded and agreed, "Okay, you wait, I'll go with you." ”

With that, he turned back to the podium to pack up his things, and then glanced at all the students in the classroom who were looking at him with puzzled and curious expressions.

"Let's get out of class, classmates." With that, he turned and followed the two officers out of the classroom.

The students in the back classroom were instantly fried, and all kinds of discussions and rumors spread privately, some people said that Professor Li's misbehavior was reported by others, or that Professor Li was a science maniac who was discovered by the military, etc., but in fact, no one really knew why Professor Li was taken away by the military.

Professor Li was taken into a jeep military vehicle, followed by two military trucks, and these soldiers with real guns and ammunition jumped neatly on the truck, and the convoy drove out of the campus.

After the convoy left the campus, it has been driving along the winding highway by the sea, Professor Li in the car was sandwiched between the two officers on the left and the right, looking more like a fugitive arrest, which made him uncomfortable, but what shocked him even more was that he was still behind, the convoy was unimpeded all the way after getting on the highway, except for their lonely convoy, there was not even a companion vehicle around!

Obviously, the entire highway is blocked, why? The more Professor Li thought about it, the more confused and uneasy he became, and he didn't seem to have done anything illegal or disciplined.

"Please let me get out of the car." Professor Li pleaded.

"I'm sorry, Doctor, we can't let you get out of the car, the highway is blocked at the moment." A captain next to him declined without the slightest room for negotiation.

"This ......" Professor Li didn't know what to do for a while, and he couldn't beat him, let alone jump out of the car and escape.

Suppressing the irritability in his heart, he had no choice but to accept his fate in uneasiness, and the convoy continued to speed forward, and an hour later, the convoy entered a heavily guarded military airfield.

After getting off the bus, Professor Li was immediately "invited" by the two young lieutenants, one left and one right, as if they were clamped onto the military helicopter that had been waiting on the tarmac for a long time, and with the roar of the propellers, Professor Li was taken away from the port city where he had lived for nearly ten years by the climbing helicopter.

It was nearly two or three hours of turbulence in the air, and it was late at night when the helicopter landed, and Professor Li was handed over by the two captains to a calm officer who was nearly 30 years old as soon as he got off the plane, and Professor Li also deliberately looked at his military rank, which was a major.

He saluted Professor Li with a standard military salute, and then said politely: "Dr. Li has worked hard all the way, please come with me." ”

Only then did Li Mingtai notice the surrounding environment, except for the strict guard of soldiers, this place looked like a military base, except for the outline of the continuous peaks, the terrain environment was basically not clear, but it could be judged that this was a specially built mountain bunker base.

He was escorted by the major and the soldiers into the largest mountain bunker base in front, the structure of the base was beyond Li Mingtai's expectations, he did not expect to be able to create such a huge mountain bunker base in China, and the facilities and supporting facilities in it were quite perfect.

Inside, the huge base structure is brightly lit, and there are all kinds of planes that are constantly taking off and landing, as well as various military trucks, tanks, and even ballistic missile vehicles coming in and out!

It's like a well-equipped military base!

But what is it? Why did they bring themselves here? Professor Li's mind was full of questions.
