In the year 4000 AD, the earth entered the Age of Discovery, 1500 years ago.

4,000 years ago, the earth was still in the age of cold weapons. More than 2,000 years ago, thermal weapons appeared on Earth. In the early days of thermal weapons, two global world wars broke out on Earth. Around 2000 AD, the earth was in a period of post-war peace. Up to now, human beings have gone out of the solar system, and earthlings have appeared all over the galaxy, mainly on the earth, Mars, and the moon.

In the history of human development, there will always be some amazing cross-generational scientists who have pushed the whole earth forward.

Newton's classical mechanics, Faraday and Maxwell's electromagnetism, Einstein's theory of relativity, quantum theory, weak electricity theory, chromodynamics, Big Bang model, borderless assumptions, supergravity, superstrings.

Of course, the most famous is Albert more than 2,000 years ago. Einstein.

Einstein's theory of relativity played a crucial role in the exploration of the universe of the solar system, and his ideas and theories went beyond the science of the time so much that some later generations jokingly said that Einstein traveled from the future to the time.

Another scientist who was called the twin star of the solar system along with Albert Einstein was Mark.

This scientist, who is no less scientific than Albert Einstein, proposed the theory of subspace around 2200 AD. He pointed out that when the speed reaches a critical value close to the speed of light, it will break through the real universe and enter subspace. In subspace, gravity is extremely strong, and no life forms exist.

However, subspace is closely connected to the real cosmic space. To be in subspace, you have to be faster than the speed of light, but once you enter subspace, all the restraints are loosened, and the speed can increase at the geometric speed of light.

Ten years later, Mark further refined the theory of subspace by proposing that subspace is the "interior" of real cosmic space. Taking advantage of this, humans can experiment with subspace curvature flight.

Two years later, mankind truly broke through the shackles of space and achieved a preliminary subspace curvature flight. It's not perfect, and there are still a lot of risks, but time makes up for it.

In 2300 AD, a space explorer discovered a new energy source on an uninhabited planet. After bringing it back to Earth, scientists have found that the efficiency of this energy source can reach almost 100%. Its small size, light weight, and large energy quality make scientists immediately fall into a state of obsession. If this new energy can be broken down and utilized, it will cause a new energy revolution. And spacecraft no longer have to worry about running out of space energy and other problems such as the heavy nuclear fuel.

In 2380 A.D., this new energy source, named Jingneng was widely used in large public factories and spaceships.

In 2400 AD, World War I broke out. More than 400 years of peace have been broken, and the root cause of this is crystal energy.

In times of war, the fastest growing industry is naturally the military industry. The strongest individual weapon mecha came into being. With the fierce war, various types of mecha were born accordingly. And the performance of the mecha is also improving from generation to generation.

In 2430 A.D., the war that lasted for thirty years came to an end. The defeated coalition fled to Mars and fell to the roots. However, the unequal distribution of profits among the victorious countries led to the collapse of the alliance, and the war almost broke out again. Eventually, the weaker side is forced to settle on the moon, which has been developed and transformed.

Since then, the Earth, the Moon, and Mars have formed a three-legged situation in the solar system, restricting each other.

In the year 2480, the Earth Space Expedition encountered a mysterious spaceship in space. After the two sides meet, they realize that they have encountered aliens. Seeing that the enemy was outnumbered, the mysterious spaceship opened fire first, trying to take advantage of the chaos to escape. The Earth Expedition fought back desperately, and in the end, both sides were killed.

In 2482 AD, an alien fleet headed for the solar system.

In 2485 AD, Earth detected an alien fleet that would arrive in the solar system in March. When I think of the image that an expedition sent back to Earth three years ago, I know that the comer is not good. In order to jointly defend against foreign enemies, the Earth, the Moon, and Mars concluded an alliance called the Federation of the Solar System.

In 2486 AD, the fleet arrived in the solar system, and the two sides negotiated unsuccessfully, and officially went to war.

In the early days of the war, the Solar System Federation forces were repeatedly defeated, and the ratio of losses on both sides was as high as twenty to one.

I have to say that the alien technology military force is indeed much stronger than the solar system federation at that time. But there is a saying on Earth that the master is killed by fists, and the alien fleet, which faces thousands of times more enemies than itself, finally pays a terrible price for underestimating the opponent. The Solar System Federation stuck to its homeland, taking advantage of the time and place, and the alien fleet could not keep up with the supply, which contributed to the victory of the Solar System Federation. The alien fleet is all buried in a foreign land.

On the battlefield, it is not only the quality that determines the victory, as long as it is not the advantage of overwhelming momentum, the quantity is also the key to victory.

This was an important reason for Germany's defeat to the Soviet Union in World War II. The Germans are rigorous in their bones, and the same is true of the tanks they make, which have advantages in all aspects. The Soviet tanks were very rudimentary, but Germany made one tank and the Soviet Union was able to build ten, and quantitative changes caused qualitative changes.

The war ended, but it didn't end there. Seven years later, the defeated alien fleet returned, bringing with it half the military strength of the home planet, intending to take the solar system in one fell swoop.

As soon as the two sides fought, the alien fleet felt deeply uncomfortable. The strength of the solar system in front of us has made a qualitative leap. A lot of technology seems familiar, but it's really vague.

This reason, of course, is inseparable from the most essential talent of the solar system, learning. To put it bluntly, it is an amazing imitation, and of course it can also be said to be plagiarism. As long as something new appears, with a sample, it can be decomposed, digested, improved, reorganized, and finally become something unique to itself in a short period of time.

When the aliens realized this, they realized what a terrible enemy they had provoked. This race, as long as it is not exterminated, has a chance to develop again.

In the past seven years, mankind has deeply studied extraterrestrial technology and integrated itself with extraterrestrial technology. Therefore, there is enough strength to contend with the alien fleet.

In 2497 AD, the Supreme Commander of the Alien Planet signed a truce with the Federation of the Solar System. And signed an alliance contract to declare common development.

As for the loss and compensation of both parties, there is no mention of it. For the solar system, it is not clear how many hole cards the opponent has, and a truce is the best decision. What's more, the solar system is just starting out in space, and such an ally is needed. For aliens, even if the overall strength of the Solar System Federation is inferior to itself, it is not a soft persimmon, and you can pinch it if you want. And such a terrifying ability to steal from the solar system can enable such a race that has just entered the galaxy to develop as soon as possible, with unlimited potential.

After really understanding the history of the solar system, it turned out that it was also a warlike race. In this planet called Earth, which is the origin of human beings in the solar system, it has almost grown up in civil wars, even if it is peaceful on the surface, the secret fighting between countries is continuous, and there are more than 200 countries on the small planet. Such a race is terrifying to think about.

After the alliance between the two sides, the solar system truly entered the Age of Discovery. Later, he came into contact with various different planets, empires, federations, and solar systems, as the Yaks who invaded the solar system at that time said, and their status and strength developed rapidly.

By 4000 AD, the solar system had become one of the ten governing stars of the Milky Way. Although it is ranked ninth, its speed of development does terrify other planets. At that time, the Diko people, who had no voice in the galaxy, also rose in status because of their attachment to the solar system.

Everything seems to be so good, steadily developing, superior status. But the truth is not as simple as it seems. The galaxy is ruled by humans, and if there are people, there will be strife, and there will be **. A new crisis has quietly come, under the starry sky, the undercurrent is surging, how many heroes are hateful, and how many heroes are proud of the sky, crisscrossing the galaxy.
