He is a big shot again.

Ling An rarely attracted attention.

Huaji is a kid with his family. His father and his father are friends who have been together since childhood. The two families are also familiar with each other, and the relationship between Huaji and the three brothers and sisters of the Ling family is similar to that of their own brothers.

But later Huaji's father joined the army...

He was a few months younger than Ling An. Because Ling An was the second child at home, Hua Ji was used to calling him his second brother.

"Huaji!"

Hua Ji felt the sound in the classroom suddenly quiet, and his heart trembled. He looked up and saw Teacher Chen, who was giving a lecture, staring at him with a frown.

This kid, please be blessed. Ling An shook his head secretly.

"Huaji, what did you just say below?"

Teacher Chen was a little unhappy. What she said now is the focus.

This little fat man is still very clear about it. He is smart and loves to be absent-minded. This is not the first time. Teacher Chen decided to teach him a lesson.

"Forehead……"

Hua Ji touched his head and was about to make up a reason, but he saw that Teacher Chen's face changed.

What's wrong?

Hua Ji was a little confused and subconsciously looked at Ling An beside him, but found that his second brother looked back with a little surprised expression.

Could it be...

Ling An had an ominous premonition in his heart.

Anyway, everyone has looked back, and it’s okay to look back by themselves.

This time, Hua Ji almost fainted from scare.

Ling An was also very surprised.

Because there was a little movement in the back door just now, Ling An, who didn't care about it, also became curious because of the change in Teacher Chen's expression, turned around and looked over.

The back door is open and the principal who always likes to stand in position C is now accompanied by a middle-aged man with a smile on his face and a gentle expression. From the outside, he looks like a middle-aged man in his fifties.

The middle-aged man dressed simply, but someone had already exclaimed in the classroom.

Earth Federation, Asia's Chief of Defense, Zhou Yang.

The legendary S-class warrior fought bloody battles on the Martian battlefield for more than 30 years and made many extraordinary achievements. It was not until the last two years that he had returned to Earth from the front line and became the Chief of Defense of Asia because of his age and the new S-class warrior.

Such a legendary figure actually appears here!

By the way, President Zhou Yang’s high school alma mater is Yuanyang No. 1 Middle School! No wonder he appears here.

This is indeed a big shot, but Huaji is...

Looking at Hua Ji, he was already pale at this moment.

No, why do I have such a little memorization? I was caught being abandoned when General Zhou Yang came to inspect... At this moment, Hua Ji's expression seemed to have eaten Coptis chinensis. He seemed to have seen that the principal would call him to the office alone after class, and then...

Hiss! Can't do this!

This kid Huaji is indeed smart. When he turned his eyes, he came up with his idea.

At this moment, everyone was still in the excitement and surprise brought by General Zhou Yang. Hua Ji suddenly said calmly:

"Teacher Chen, I was just thinking about the connection between the discovery of g matter and the entry of humans into the fortress era. I couldn't help but ask Ling An if I didn't understand something."

"I'm so sorry that I'll write a review." After saying that, Hua Ji bowed to the teacher, making Teacher Chen stunned.

Ling An didn't expect that Hua Ji would use a trick to induce trouble! Seeing Hua Ji blinking at him as he hooked his body, Ling An's mouth twitched a little.

Based on his understanding of Teacher Chen...

"It's okay, the teacher forgives you." Teacher Chen also recovered from the arrival of President Zhou Yang. Seeing the principal secretly giving him a gesture of continuing to teach, and then heard the fat man Huaji say this, and nodded slightly to express his forgiveness.

"Just," Teacher Chen changed his tone. "This test point is indeed important. Ling An, why not get up and answer it. Huaji, you can sit down."

Sure enough... Ling An sighed in his heart.

I felt that the students' eyes were all on him, and Ling An could not see behind him, but President Zhou Yang and the principal must have also been watching him.

However, Ling An was not too nervous. History is his specialty, and he reviewed this piece of knowledge last night.

After organizing the language, Ling An said calmly:

"The discovery and application of g matter is of great significance to the opening of the Fortress Age. First of all, from the time node..."

While Ling An narrated, he subconsciously reviewed this history in his mind:

In 2050, Chinese scientist Feng Zixuan discovered g substance.

This is an extremely mysterious substance. It accounts for a huge proportion in the universe. It not only exists in space, but also in living organisms, and contains huge energy. The scientific community speculates that this is a type of dark matter. After intense discussion, it was finally named g matter.

Using G matter, humans have successively solved energy problems, material problems, and even made major breakthroughs in the field of biology.

At the same time, in the investigation of the cult organization: the Fallen Gods Society, the relevant departments intercepted the information that "within fifty years, the abyss will arrive on Mars, and God's servants will cross the galaxy and come to the earth to help the Fallen God reborn and turn the earth into a new paradise."

The official secretly dispatched personnel to set up a special organization. In the confrontation with the Fallen Gods, he contacted three alien races as pioneers for the first time.

In the end, after paying a heavy price, three alien races were wiped out and the strength of the Fallen Gods Association was greatly weakened. Unfortunately, the Fallen Gods Association was unable to complete the settlement, and it still existed until today in 2183.

At this time, humans had the ability to navigate in the solar system with the help of the technological revolution brought by G matter, so they organized personnel to arrive at Mars for exploration. Sure enough, they discovered that there was a huge abnormal space fluctuation in the location near the North Pole of Mars.

The oracles of the Fallen Gods Society were not fabricated out of thin air. In addition, the three alien pioneers I encountered before, after studying their corpses, they found that they were not the same species as humans. Combined with the information obtained from the Fallen Gods Society, senior officials of various countries believed that foreign races were about to appear on Mars and that the invasion of the earth was likely to be true.

Next, with the strong support of the country led by China, the fortress plan was launched.

All countries on the earth united, and the United Nations was upgraded to the Earth Federation. While maintaining independence, each member state was committed to resisting foreign aggression. The unified federal currency was issued, the technical barriers between countries were actively broken, and mankind began to develop rapidly.

All of this is inseparable from the application of g substances, which solves the differences caused by energy issues among countries.

The highlight of the fortress plan is to build a huge launch tower on Mars, which can generate an internal shield that uses g matter and Mars magnetic field to maintain it and cover the entire Mars. This launch tower is called the "Zhoutian Tower" for the initial sacrifice and defeating the organization of the Fallen Gods Association.

In order to protect this launch tower, humans also need to build a huge fortress and need a large amount of defensive forces to guard it.

So, in the next 30 years, humans united and first established a January route from Earth to Mars, and then built the largest miracle city in history: the fortress of humanity, near the South Pole of Mars.

With the help of G matter, humans have successively completed the construction of the Celestial Shield Tower and made breakthroughs in biotechnology, allowing soldiers who have received special enhancement to adapt to the Martian environment.

Later, the invention of using g matter to further strengthen the "engine" of human warriors has doubled its confidence in resisting aggression. Three batches of armed soldiers, a total of 900,000 people, carried the engines and received relevant training, became the first guards of the human fortress, and they were the first members of the Glorious Army.

It was 2095, and the abyss in the prophecy was still not opened, and some countries had complaints, but the Earth Federation still decided to strengthen its defenses. In addition to continuing to manufacture systems and increase the scale of the Glorious Army, it also built a large number of war resource production facilities, increased a large number of machine troops, established missile systems, air strike systems on Mars, and established defense lines outside human fortresses.

Just as the New Year is about to usher in the late 2099, some countries began to question whether there were real aliens. The Earth Federation was in dispute, and even caused the human fortress to be affected and became chaotic.

The abyss is opened.

As alien races descended, these creatures had powerful and strange powers that humans could not imagine. Their wisdom was not lower than that of humans, but they did not develop technology comparable to humans. Instead, they relied on their own powerful strength and quantity to almost destroy all defense lines on Mars except human fortresses in a short period of time.

Fortunately, the passage does not seem to be fully opened, and the speed of the arrival of aliens gives humans a chance.

With the help of the previously established G material nuclear weapons strike system, after making huge sacrifices, humans successfully destroyed those pioneers and won a precious opportunity to breathe.

It was also this time that the large-scale use of G material nuclear weapons to attack, which made humans even more terrified to discover that even the most advanced and most lethal G material nuclear weapons cannot kill many existences in the alien race.

But no matter what, this nuclear attack also caused the alien races, which had not yet been assembled, to give up on continuing large-scale attacks. The alien races did not occupy the defense line outside the human fortress, but retreated back to the abyss, which is the passageway entrance to the North Pole of Mars.

The Earth Federation quickly used the war resources it had accumulated over the years to fill the gap in defense of human fortresses. Perhaps the strength of the alien race gave all humans a sense of crisis. The Federation almost recovered its previous defensive power at the expense of overdrawing the entire Federation's economy, but also expanded the scale of the Honorable Army to 3 million.

In the following time, they continued to resist the invasion of alien races. It was not until recent years that they had gained an advantage.

The Fortress era began, marking the war against alien aggression from 2099 to 2100.

And everything in it, whether it is the January channel, the construction of the Zhoutian Tower, the solution to energy problems, or the invention of the "engine", is inseparable from g matter.

It can be said that without the discovery and application of g substances, there would be no human beings today.

Therefore, Dr. Feng Zixuan, who discovered g substance, was also listed as one of the ten most influential people since the steam era.

"...g. What I know about the relationship between matter and the fortress era is roughly these points."

Of course, Ling An would not finish everything. He just explained it as the part of the test point.

The classmates around him all looked at him with admiration. Ling An summarized it very well, and there were many things that were not mentioned in the book.

Even President Zhou Yang and Principal Zhou Yang and the principal who were listening to the class behind him smiled and nodded constantly.

"Student Ling An, you answered very well, please sit down. But everyone should pay attention to it. When writing it on the answer sheet, you don't need to summarize those points in such detail. Just summarize them briefly." Teacher Chen was also very satisfied with a smile in his eyes.

As soon as Ling An sat down, Hua Ji next to him looked at him with admiration, but at this moment, General Zhou Yang and Principal were still behind, and he didn't dare to speak.

"Okay, let's continue to look at this test point..."

After class, the class monitor Su Man went out and jogged back. She came to Ling An's table and said to him with a slightly red face:

"Student Ling An, Teacher Chen asked you to go to her office."

Ling An was stunned, looked at Hua Ji, who was also a little confused, and put down the mock test paper in his hand.

"I understand, thank you, squad leader."

Looking at Ling An's departure back, the squad leader Su Man swallowed. All this was seen by the little fat man Hua Ji and kept smirking in his heart.

"Report!"

As soon as he entered the office, Ling An saw the figure sitting opposite Teacher Chen and was shocked.

President Zhou Yang?!
Chapter completed!
