Your white moonlight is so beautiful

On the stage, Mr. Luo put down the lesson plan, straightened out the non-existing folds on the suit, and said solemnly: "I feel the students' desire to fast-forward to the underwater world."

The audience roared with laughter, and the class officially began.

Then they discovered that the teacher actually put down the lecture notes and started to talk about the underwater environment.

Some of the classmates took the lead in booing, and there was a burst of applause, and the teacher couldn't help laughing.

Sure enough, everyone was very attentive in this class.

Interest is the best motivation for learning. It is hard for people not to be curious about his living environment when a genuine mermaid came to the class.

However, the combat environment is not the same as the animal world. Humans often say that they have conquered the vast universe. In fact, from the ancient earth period to the current interstellar empire era, technology has indeed brought earth-shaking changes to life, but human beings still Small--

The teacher turned on the stereoscopic astrograph, and the huge interstellar spiral arms centered on the first galaxy, forming a spectacular silver swirl belt, and the outer ring is a wider unknown and dark.

In this way, the interstellar territory of the empire was presented in front of the students.

"Since the three major technologies of 'artificial magnetic field', 'artificial natural satellite' and 'meteorological environment control system' have matured, humans have developed a large number of new habitable stars, and the colonies have broken through the Milky Way, and once expanded several extragalactic galaxies, but followed What is new is the new predicament—in the new universe, we have encountered new space species, and the bug swarm is one of them.”

"It was the darkest period, and that disaster caused the total population to drop by 90.00%[-]."

"In desperation, human beings once again broke through the limit of evolution, and began to use a magnetic force called "spiritual power" to resist the bug swarm, and finally defeated the bug swarm..."

The teacher spoke in a deep and slow voice, and the students were all attracted by this tragic history.

"The disaster brought about by the bug swarm is not only that human beings are reduced to become their food, but at the same time, they have also destroyed many civilizations and technologies."

"The remaining two percent of the population have made great sacrifices for the continuation and development of the entire human race."

"Humanity began to implement militarized management of the whole people, and there were rigid indicators from birth to education. It was a period of despair, because the number of insect swarms was hundreds of billions of times the population. Do you know what a concept of hundreds of billions is?"

The students were silent, as if they followed the footsteps of human history and came to that kind of despair and helplessness.

"Afterwards, the academic circles have been arguing - what is the most important reason for human beings to win the final victory and regain a bright future?"

"Many scholars believe that the receding of the insect swarm is not because humans once again defeated the unknown universe, but because they reproduced too much and eventually starved to death."

This time, the audience did not laugh because of the teacher's cold humor.

After spending such a high price, the insect swarm was not defeated by them in the end.

It sounds so hopeless.

If one day the swarm of insects invades again, can human civilization, which has developed for thousands of years, compete with this interstellar creature that has no intelligence and only knows how to eat and lay eggs?

Seeing that the atmosphere was too depressing, the teacher walked down the podium slowly and said, "So there was a saying that was widely circulated later. I don't know if the students have heard of it—'Human beings can never reach a reconciliation with the rustling.'"

The audience finally burst into laughter.

This is a popular video on the Xingwang platform. The five-year-old little girl killed a cockroach. She couldn't help being irritable when she saw the bug, but also felt very guilty, so she cried and asked her parents to comfort her.

The parents held back a smile and asked her if she regretted it.

The chubby little loli was crying with snot and tears, hiccupping and saying: "I will never... woo burp... can't... burp... and rustling things, woo burp, You can't reconcile with Shushushu! You can't!!"

After speaking, he shook his head heavily.

A large number of netizens were so cute that their hearts melted.

An excellent lecturer is very good at adjusting the atmosphere, and the content of the class is fascinating. Nan Ruoyu was also attracted by his content after listening to the class for the first time.

——It is indeed more interesting than searching and reading texts on the Internet by himself.

He began to understand why human beings vigorously develop education, life is so short and fragile, and human beings have too many things to pass on.When a disaster strikes, the experience left by the predecessors may have an important impact on the destiny of the entire human race.

After being in awe of nature, it's time to explore nature.The underwater world is the main direction of this class. To enter the seabed, various detectors and underwater operation mechs are involved.

Theoretical knowledge is not as magnificent as human history, and many things have to be memorized by rote. This section has become relatively boring. The teacher will intersperse some interesting little knowledge points from time to time to keep the students' concentration.

Nan Ruoyu heard the girl next door chatting:

"I heard that all the Zerg have been repatriated to the habitable planet."

Ren Qiuhan asked in surprise: "Really? When did it happen?"

"Haven't you been on Xingwang these two days?" Another girl was more surprised than her: "It's a trending search, and there are still people arguing about why they can't be treated equally..."

"Hush!" Ren Qiuhan quickly stopped her, and glanced at Nan Ruoyu by the way.

The girl stuck out her tongue and stopped talking.

After 2 minutes, they chatted about a new topic: "...Why have you been there these two days? You don't even know that 'Fire Spider' escaped from prison, so you go to anonymous forums every day?"

Ren Qiuhan answered casually absent-mindedly.

The sky light came in from the window, and Nan Ruoyu's whole figure was glowing, as if all the light would actively gather around the shark.

Nan Ruoyu listened carefully, her snow-white eyelashes fluttered like two small fans.

Such a person, whether on land or in the deep sea, no one can ignore his existence even if he hides in a corner.

Ren Qiuhan couldn't understand the special words such as underwater sonar, water pressure resistance, and new energy condensation reaction, and the girl next door to her just wanted to attract Nan Ruoyu's attention, and she glanced over from time to time.

Sharks are really cold...

Nan Ruoyu's facial features are aggressive and gorgeous, and his expression is usually so cold that people dare not approach at will - as long as Shihan is not around, Nan Ruoyu seems to seldom change his expression.

When he showed the expression of "stay away from strangers", he looked more like the dead Marquis.

Ren Qiuhan saw that the girl kept glancing at her, so he deliberately turned his face to talk to Nan Ruoyu: "You really don't remember me?" She reminded in a low voice: "Senior Liang talked to you that day..."

Shi Han took care of the admission procedures for him, and Shi Han also called "school doctor teacher" when he was seeing a doctor for allergies.So Nan Ruoyu really didn't know who Senior Liang was, let alone the one in front of him.

As soon as Ren Qiuhan finished speaking, Teacher Luo called on the stage and said, "Qiuhan, answer this question."

Ren Qiuhan's expression froze, she was so distracted and chatting, she didn't even know what the teacher was talking about.

Teacher Luo was just casually pointing out. Seeing the girl's embarrassment, she thoughtfully repeated the question: "What are the advantages of the shaftless pump jet propeller?"

Ren Qiuhan faltered for a long time, then suddenly had an idea and said, "Teacher, I just don't quite understand this question, so I asked the classmate next to me for advice."

The student in the back row who was also disturbed by the chatter let out a "chih".

Ren Qiuhan heard someone whispering: "No way, no way, the students of the Department of Marine Exploration don't know about shaftless pumps..."

Seeing Mr. Luo's expectant eyes, Ren Qiuhan panicked even more, and stood there embarrassed and at a loss.She was thinking that sooner or later she would switch majors and go to medical school. She hadn't listened to the courses of the Department of Oceanographic Exploration since the beginning of the semester.

But she didn't know, could Nan Ruoyu know?

According to her and her little sisters, the merman who has never been to school is a fish that slipped through the net of nine-year compulsory education. He may not even be able to write the four words shaftless pump spray!

Teacher Luo didn't think too much about it. After hearing what she said, she turned to Nan Ruoyu and said with a smile, "Student, this seems to be the first time I've seen you. I wonder if you can answer this question."

Nan Ruoyu was listening to the class attentively, but was interrupted one after another by the chatter next to him. As soon as he stopped, he thought of Shihan again.

Xiaolongren doesn't go to class recently. He is doing special training for the public competition in a month. He leaves early and returns late every day, and he doesn't reply to text messages.

When the teacher asked him, Nan Ruoyu had just recovered.

Ren Qiuhan showed a smile of watching a play.

He seemed to have a focus effect, and the eyes of the entire classroom were focused on him.

Nan Ruoyu was stunned for a moment, and said: "Pump jet propulsion was first used in the configuration of submarine weapons. It drives the impeller to do work on water, and relies on the reaction force to generate propulsion. [1]"

"The front guide wheel of the pump jet propeller can reduce vibration and noise, and the rear guide wheel can not only improve the efficiency of the propeller, improve the propulsion wake, but also eliminate the dumping moment."

"But the biggest problem with the shaft push is the noise from the mechanical vibration and the improvement of the anti-cavitation performance," Nan Ruoyu said here, endured it, trying to save some face for human beings, and finally couldn't hold back, said: "Say To be honest, it's really noisy."

The complaints from the residents of the deep sea caused joyous laughter from the audience.

Nan Ruoyu was just narrating a fact: "It is said that the shaftless pump jet propulsion has improved this shortcoming, um... I can only say that I feel your sincerity in improving it, but the effect is not as good as expected."

The students laughed even more happily.

Nan Ruoyu really thought they were noisy, the mermaids were already sensitive to hearing, and every time a detector went into the sea, there would be no peace for more than ten nautical miles.

It's not that he hasn't beaten the submarine probe.

What annoys the fish the most is that every time he finishes hammering, the people on the shore will send more machines to fish the wreckage back to study, so it becomes even more noisy. Not only that, the salvage machines tend to stir up the sediment on the bottom of the sea, which is huge. The moving power of the animal will also merge with the undercurrent of the seabed to form a vortex, and all kinds of marine life will scurry around, which is really disturbing.

There are some sea areas inhabited by grumpy mermen, such as a delta called Bermuda in Blue Star. When a ship comes to the bottom of the sea, the merman beats a hammer until no ship or probe dares to go there.

Nan Ruoyu is not so irritable. He lives under the sea just to avoid being chased and killed, and he doesn't really like fighting with detectors.

After Nan Ruoyu started surfing the Internet, she checked all the things that offended him in the sea immediately, and then wrote it down in her little black notebook, hating it every day.

But recently, the little black book is full of Shihan, but Nan Ruoyu found that after closing the little black book, he still likes him very much. (o^^o)

The teacher couldn't help laughing and said: "It seems that we still have a lot to improve." He said to Ren Qiuhan: "These are basic knowledge, and it doesn't matter if you don't know it. You can ask him, this classmate can teach you a lot.”

Ren Qiuhan said in a low voice: "I have never been exposed to theoretical knowledge before..."

Teacher Luo said with a smile: "I believe Nan Ruoyu should not have access to the theory, but he proved to us all that practice brings true knowledge. A submarine detector is quite expensive. I hope that next time I meet you, you will be able to learn more about it." Wan be merciful."

Nan Ruoyu saw that he had a good attitude and the class was well taught. After thinking about it, she nodded seriously and said, "I will try my best."

The class laughed again.

Many people looked at the sharks with different eyes from before.

As the overlord of the sea, Merman has a cold and arrogant temperament, but when he speaks solemnly, he seems to run wildly at the cuteness of the students.

Some students even had an absurd idea: Mom, I also want to be beaten by a shark...

Ren Qiuhan was told to sit down by the teacher.

She was sitting on pins and needles, until the end of get out of class, Ren Qiuhan felt that the eyes of the students around her were full of ridicule, and they almost passed the second half of the class absent-mindedly.

But the students have long forgotten this, and they took out their communicators after class to share their complaints from the bottom of the sea.

"Universal Basic Environment" is a big class with four consecutive lessons, and there is a break of 10 minutes between the first two and the last two.

Many daring students gathered around, trying to strike up a conversation with the shark.

Because they were more curious about Nan Ruoyu, fewer people surrounded Ren Qiuhan.

This is a treatment courtesans have never had in the past.

Ren Qiuhan has always felt that she is likable in every way. She has learned to deal with all kinds of elders, teachers, and classmates since a long time ago, and thus gained a lot of convenience.

But Nan Ruoyu doesn't have to do anything, there are many people who want to get to know him.

Ren Qiuhan is the class representative and assistant of this class. She is mainly responsible for registering attendance, class points for answering questions in class, and urging assignments. If there is a class adjustment from the teacher, she will also convey it.

Due to the excellent attendance rate of the military cadets, the job content of the classroom teacher assistant has become very simple and can earn 0.5 credits.

Ren Qiuhan served as the class representative of three courses, and he was regarded as a celebrity in front of the teacher.

Surrounded by a group of people, Nan Ruoyu is actually not used to living in a compact group, but when he thinks of being able to live with Shi Han, he thinks it's nothing.

Isn't it just answering the question?

He still creates problems.

After class, the classmates gathered around Nan Ruoyu, and Ren Qiuhan had no one to care about. In order to ease the embarrassment, she took out the assistant optical brain to fill in the attendance score.

Fill in 10 points for punctual attendance, 5 points for late arrivals and early departures, 0 points for absentees, and the teacher will summarize the scores at the end of the semester.

Each teacher teaches several classes at the same time, and will not remember the specific situation of each class, and just take the formula and run the result at the end of the term.

When Ren Qiuhan filled in Nan Ruoyu, he paused with his fingers, and then gave him a score of 0.

After a while when she checked again, she found that the number had changed to "10".

Ren Qiuhan glanced at the crowd next to him with a guilty conscience. Everyone was chatting enthusiastically, and no one noticed this side.

Ren Qiuhan came to the teacher, blushing and embarrassed: "Teacher, I'm sorry, I'm a girl, and I used to study liberal arts. The theoretical foundation is indeed too weak."

Teacher Luo belongs to the kind of class with high mood and very concentrated attention-this kind of concentration is used on all students.

Because he can arouse the curiosity of the students in class impromptu, he can always mobilize the atmosphere very well.

But at the same time, this kind of class consumes a lot of energy, often after four classes, it seems to have completed a triathlon, and sometimes I have to drink some glucose to recover when I return to the office.

Teacher Luo opened the lid of the thermos cup, rubbed the center of his brows, and said: "The first grade has a lot of basic theories, and these nouns are common words. If you can't keep up, take the time to preview it. If you recruit people who learn well in the end, it won’t affect you.”

The teacher really thought she was worried about not learning well.

However, Ren Qiuhan wanted to take the opportunity to ask the teacher to make up lessons for her, so as to establish the image of a stupid bird flying first.

Because I was too focused in class, I could not pay attention to some other problems. Now I am relaxed, and some subtle feelings arise from the bottom of my heart.

Teacher Luo said: "You read it first, and then ask me if you don't understand anything."

Ren Qiuhan was a little disappointed.

She felt that the teacher did not pay as much attention to her as before.

Teacher Luo put the lid on the vacuum flask, and looked at that special student curiously.

Ren Qiuhan noticed the teacher's gaze, and became even more certain that it was all because of the shark.

It was almost time for class, and she returned to her seat sullenly, and suddenly let out a soft "ah".

No one paid attention to her at first, until Ren Qiuhan said, "Where is my communication terminal?"

At this moment, Nan Ruoyu's classmates who were crowded with people had almost dispersed.

Ren Qiuhan's eyes fell on Nan Ruoyu immediately, she stared at him and asked word by word: "Have you seen my communication terminal?"

Nan Ruoyu said lightly that she didn't know.

Ren Qiuhan said anxiously: "I went to ask a question, and when I came back, the communication terminal was gone!"

"What's wrong?" The dispute in the first row quickly attracted the teacher's attention.

Nan Ruoyu said: "Your communication terminal is missing, why are you asking me?"

Ren Qiuhan's eyes were reddened, and he looked like he was about to cry, and said, "I didn't say you took it, I just asked if you saw it, why are you so fierce?"

Nan Ruoyu: "..."

At this time, a nearby classmate came forward to smooth things over and said, "Qiuhan, Ruoyu has been talking to us just now, no one touched your things."

Ren Qiuhan: "Then how could the good ones disappear!"

The students were blocked and had nothing to say.

The atmosphere in the classroom was very awkward. The eyes of the students flicked between Ren Qiuhan and Nan Ruoyu, and they didn't know what to say for a while.

Some students also remembered that the orcs had no financial means, and everything was subsidized by the Sri Lankan government, including tuition fees.

Combined with the recent bad news about the orcs, these people began to feel that maybe... In the eyes of the orcs, taking something away is not a big deal. After all, the detectors that humans put in the sea can also be destroyed randomly.

Once I had this thought, my tone was different from that of Si Ni: "Student Ruoyu, why don't you see if there is any in your cabinet?"

Nan Ruoyu remained motionless.

He glanced at the teacher's surveillance camera, and said coldly, "Why don't you adjust the surveillance?"

Ren Qiuhan sat down with red eyes, and said, "Go to the security room to transfer after class, don't delay the class."

However, Nan Ruoyu quickly figured it out: After class, other students should eat and go back to the dormitory. Within half an hour, the whole school probably knew that he had "stolen" something.

Brainwashing kits are usually created in this way, a bit of speculative information, plus no channels to prove their innocence.

Even if someone later came to Ren Qiuhan to ask for proof, she only had to say: "Forget it, I don't care about it." Nan Ruoyu had to sit firmly on the blame.

Nan Ruoyu pulled back the long hair on the left ear, lightly touched the optical brain switch, and a virtual screen popped up in front of him: "It's okay, I can help you locate it now."

Ren Qiuhan didn't expect that the mermaid had this ability, and said immediately: "But my ID and password were set up by my family members for me, and I don't remember them now."

Nan Ruoyu said, "No need."

Before Ren Qiuhan could react, the safety alarm of the communicator suddenly sounded in the silent classroom.

[Di-di-di-di-di-! 】

Everyone followed the sound and saw a girl sitting in the middle of the back row of the large classroom, her face was flushed, her hand was holding her schoolbag tightly, as if she wanted to drown out the sound.

Her name is Lin Qianqian, and she is Ren Qiuhan's roommate.

Just now during the class break, she received a message from Ren Qiuhan asking herself to help keep the communication terminal.

Lin Qianqian didn't know what to do at first, but just followed suit, but when she heard Ren Qiuhan looking for the communicator in class, she quickly understood what was going on, and was ready to watch the shark's show.

Who knew that Nan Ruoyu would keep such a move!

Some students whispered: "As expected of Professor Han's last disciple."

"The major of combat information management has always been mysterious. I heard that it specializes in espionage."

"Oh, is it so cool? I would have applied for that major if I knew it!"

"Damn, you are stupid! The whole world knows that this profession produces spies, how can you find a job?"

"Yes..."

……

The students' attention was still focused on Nan Ruoyu's black technology. Lin Qianqian had an idea and said, "I was just joking with her. I didn't expect to scare her." After speaking, she stuck out her tongue and sold a cute.

Lin Qianqian is Ren Qiuhan's best friend. The two live in the same dormitory, so they are always inseparable.On the other hand, the relationship between the two of them has always been actively maintained by Ren Qiuhan - because Lin Qianqian's uncle is the director of Duluth Medical College, Ren Qiuhan has to entrust him with the matter of changing majors.

It's not a serious matter when the girlfriends are joking around, and if they accidentally make a joke, it's not serious.

Ren Qiuhan glanced at her gratefully, and then said: "Didn't I just say that you can look for it after class is over, because Ruoyu's reaction was too intense."

Actually beat back again.

Nan Ruoyu raised her eyebrows, but didn't say a word.

Teacher Luo cleared his throat and said, "Okay, it's time for class, if there are any problems, we will deal with them after class."

He turned on the projector, and what appeared on the screen was not the handout, but the attendance sheet—in the rows of full attendance lists, Nan Ruoyu's row of "0 points" was particularly eye-catching.

The students in the front row could tell at a glance: "Huh? Why are they all zero points? Didn't Ruoyu ask for leave because of allergies?"

Ren Qiuhan came back to his senses in a jerk, and denied it flatly: "Nothing, how is it possible!" When she saw the projection on the screen, she suddenly turned her head and said, "Why do you even black out my work tablet!"

However, Nan Ruoyu had already put away the optical brain, and spread his hands together: "The school system was developed and maintained by my mentor."

Professor Han once had the title of "Shield of the Empire" when he was young. His achievements in military system construction and information firewall construction are second to none in the entire Noah Empire. subject.

Apparently none of the students thought that the mermaids had the ability to break through the system built by the "Shield of the Empire", and they were already talking about it:

"It's all right, front, back, left, and right, but Nan Ruoyu is alone."

"I saw her registering attendance after class!"

"It's throwing things and changing attendance. Could it be targeting new citizens?"

"Check if she has sent Lin Qianqian a message, why do I think this joke is so coincidental!"

"Treatly treat others as fools."

……

Ren Qiuhan panicked suddenly, his face turned pale, and he began to falter in his rebuttal: "Don't talk nonsense... I didn't..."

Ren Qiuhan relied on himself as a social butterfly in the school, and some people would not be used to it if he liked it.

She looked at Nan Ruoyu as if begging for help, hoping that Yuren could help her with a word for her pity.

But Nan Ruoyu is not a character who loves fragrance and cherishes jade at all. His eyes are light gold, and when he has no expression, he looks very indifferent. He is not indifferent like a creature on a habitable planet, and his voice gives people a completely different feeling from Shihan.

The boy's voice is like the green grass with dew in the sun, and the shark's voice is like the spring water in the ethereal valley.

He said, "Do you know what sharks usually like to do at the bottom of the sea?"

The topic changed too far, and Ren Qiuhan didn't realize it all at once: "What, what?"

"Tear the lotus with your hands."

Ren Qiuhan was taken aback for a moment, but when he realized it, he said angrily, "What are you proud of? Don't you just have a face, thinking how great you are, taking advantage of the heat of the dead, and dominating the land of the living! I So what if you don't like it!"

There was a sudden silence in the classroom.

Ren Qiuhan was overwhelmed by the backlog of panic and anger just now, and her hands were still trembling after she finished speaking: it was only then that she remembered that the teacher and classmates were still there.

These words are too harsh, and it is impossible to imagine it coming from a well-behaved and polite girl.

Teacher Luo raised his eyebrows in surprise, and finally found the source of that subtlety.

It's jealousy.

The teacher said slowly: "Qiu Han, I heard that you are working in the school hospital and concurrently serving as a class representative for three courses. You may indeed be too busy, and it is understandable that you have made some mistakes in doing things."

When Ren Qiuhan heard the teacher help her speak, his eyes turned red with grievance.

However, the teacher's next sentence was:

"In order not to delay your studies, my assistant for this course should be done by another classmate."
