The door of the courtyard house has been welded dead

"Principal Cong?"

Jiang Defu's scalp went numb for a moment, his expression was startled, and he glanced back at his lost friend. As a result, Lao Ding shook the dog's tail grass in his mouth, and it was not a big deal to watch the fun.

The person who came to inform him left after informing him, but he hesitated and didn't understand what Principal Cong wanted to do with him.

"Even if you fall behind in your homework, you can't blame the principal~~!"

The Naval Artillery School is also a school. Like normal colleges and universities, it also has a corresponding system, and grades are managed by either the counselor or the department head.

Moreover, this time was not the worst test he had ever taken since he came in. A rustic boy who came from the countryside was an alien in himself when he entered the high-ranking Navy. He expected to learn a lot and become the best in the school.

Don't dream, the progress is completely different. He, Jiang Defu, must work harder than ordinary people to understand as much as possible the content of the teacher's teachings.

"Go quickly, if you dare to let the principal wait, I will peel off your skin~!"

What the bad friend said was just a joke, just to urge Jiang Defu to hurry up.

Principal Cong of the artillery school is a very nice person, and the couple are very good friends. Jiang Defu's current lover, An Jie, came together through the two of them.

One is a naive, poor and distracted naval officer, and the other is the eldest daughter of the Z family who is pampered and has a petty bourgeois sentiment.

If it hadn't been for that dance, the two of them might never be able to fight each other in this life.

"Oh~!"

With a greeting, Jiang Defu reacted, straightened his appearance, and then walked quickly towards the school's office building with a solemn expression.

On the road, soldiers cleaning the house kept saluting him, and occasionally there were school professors and other leaders passing by, so he had to salute too.

The 21-cent epaulettes here can only be said to be at the student level. Any teacher or professor has more stars on his shoulders than him.

"Principal Cong~!"

Jiang Defu opened the office door and saluted seriously.

Principal Cong was a very nice person, a very easy-going senior military officer, but because of his easy-going nature, Jiang Defu respected him from the bottom of his heart. Everyone has a scale in his heart, who is kind to him, he came from the countryside and knew very well.

Although the life of the couple was full of ups and downs, they never had the desire to lead Panfu. Regarding meeting this benefactor again, Jiang Defu showed the spirit that a student should have.

"Sit~!"

Principal Cong, who had just finished smoking, put out the cigarette butt. When he saw Jiang Defu this time, his face was less smiling and more troubled.

"Oh, you and your wife have been married for such a long time, and we, the famous people, have never asked you. Thinking of it this way, you have become a third-party husband~!"

Hearing this, Jiang Defu, who was sitting upright with his butt only touching a third of the stool, hesitated a little and made a big blush~!

"I, I...~!"

I was speechless for a moment, but I didn't expect that Principal Cong would actually say this. Jiang Defu couldn't answer, and he complained to Lao Ding in his heart.

I just told him, but I didn't expect that it would now reach the principal's ears, making it a big joke.

"A manly man, who is upright outside and at home, is transformed into a third-party husband by his lover. You are just like this bear~!"

The more he talked, the lower Jiang Defu's head became, almost drooping. What could he do? If Anjie insisted on doing this, not washing his feet, and not even getting on the bed, he just couldn't help but complain like an old man. .

"I see that your academic performance has dropped recently. It's no longer what it was when you first entered school. What's the matter? You've forgotten all your bold words~!"

One was the person he loved, the daughter-in-law he chose with his own hands, and the other was the person he respected the most. When he heard him questioning himself, Jiang Defu stood up quickly and said in a thick voice.

"No, I didn't forget, Principal Cong...!"

No one knows better than Jiang Defu himself what he was like when he was in his hometown and what he is like now. He cherishes the time now and the knowledge in school. However, his lover did give birth to a child at home that day. It took energy away. "Sit down, I can't bear to say a few words to you. Just listen when Anjie talks to you. That's all you're good for~!"

Principal Cong's expression remained calm, and he waved his hand, signaling Jiang Defu to sit down. He stood up, walked to the window, and put his hands behind his back.

"Back then, when we were on the ship, wherever we had such conditions, fresh water was reserved for people to drink. Let alone half a month, it was normal not to wash it for a month~!"

"However, the conditions now are a little better, just a little bit~!"

Speaking of what happened back then, Principal Cong seemed to have changed into a different person. He was no longer the principal of the school, but an officer looking down at the ocean from the steel giant.

When the principal spoke, Jiang Defu listened. He also knew the living conditions on the warship. After all, he had stayed there for a long time before coming to the school, from an ordinary sailor to the current major.

"Have you missed your homework?"

"No, I'm not left behind, this is my guy to eat~!"

Hearing the principal's question, Jiang Defu stood up again and said decisively.

"Okay, I'm going to take a test on you and see your academic achievements in the past two years. Let's start with something simple~!"

What Principal Cong wants is Jiang Defu's current momentum, not to compete with steamed buns for breath.

"Let's talk about submarines~!"

"Submarine~!"

Jiang Defu's head was running like a CPU, and the whole process was like a computer. Open my computer, search for "submarine" in the search bar, OK, the folder appears, double-click the document inside.

"Submarines, commonly known as submarines, are ships that can operate underwater. They can be traced back to the 16th century... and continued to develop rapidly until the th century...!"

"In the First World War, this naval ship was used in actual combat. In the Second World War, this naval vessel was used in more fields and created huge results~!"

Just kidding, have you never seen pork or pigs running? As a mid-level officer in the Navy, I have studied in military school for several years. If I can’t even learn the basics of submarines, let alone failing the exam, the school can do it. Kick him back with your feet.

"What are the countermeasures?"

I don’t know why Principal Cong specifically tested himself today, but Jiang Defu doesn’t know anything else, so rote memorization is still fine.

"Send destroyers and frigates to deploy mines to block the lanes, send observers to observe the submarine ventilation ducts, launch torpedoes after discovery, and replenish depth charges until oil stains appear on the water surface, then the results of the battle can be confirmed~!"

"Of course, the best way is to use submarines to deal with submarines~!"

Jiang Defu was very afraid of the beasts hiding deep under the water that devoured warships and even cargo ships transporting people. The artillery school fired naval guns. However, the enemy couldn't see them, so how could they aim.

The best way is to use your own to find theirs. If both of them are under the water, then it depends on their own abilities.

"Okay, my basic skills are pretty solid. It seems that I have learned everything beyond the subjects. I am good material to be a weapons commander. However, I want to hear your opinion on how submarines should deal with submarines~!"

"Listen~!"

"Listen~?"

Principal Cong returned to his seat and clasped his hands together, looking at Jiang Defu and telling him to continue talking.

"When fishing in rural areas, there will occasionally be motorized boats passing by. The sound of the propeller driven by the engine is relatively loud, so fish catchers will avoid the boats above them. Submarines cannot move underwater without their engines. and propellers, there will definitely be noise.”

I don’t know why today, Principal Cong asked him about this aspect of the school exam, but Jiang Defu still has life experience.

"Jiang Defu, if the organization needs you to leave Anjie one day, what choice will you make?"

Principal Cong nodded slightly, then nodded and looked at Jiang Defu, his eyes like thunder and lightning, reaching straight into his heart~! (End of chapter)
