Time flies by in a hurry, and never cares about people's calls... In the blink of an eye, it flows by year after year, leaving no trace. In the blink of an eye, the empire has arrived for 107 years.

Ten years passed by. In these ten years, the most exciting thing is that ultra-long-distance communication technology has finally made breakthrough progress. Input signals from one end, the other end can receive signals within an hour; the farthest communication distance, that is, the theoretical distance is 100 light years, and the current communication distance is 40 light years - within 40 light years, the communication time is enough. That is, the energy consumption is a bit large, and a lead physical battery of 100 million cubic meters can be fully connected in one signal - a call requires 1 billion degrees of electricity to be consumed! Moreover, each signal can only transmit ten seconds, no more than one megabyte of information.

Today, electricity is still the most common energy technology; as for other forms of energy such as magnetic energy, it can only be used in cutting-edge fields in a small amount. Because compared with power technology, these energy technologies have characteristics such as unimaginable and incapable of storage.

However, there has been no change in the people over the past ten years. The technological development of human society in the solar system has reached a temporary peak. With the public sale of the 100,000-ton engine of Gentian 1, space technology has made rapid progress in terms of empire or republic. In ten years, interstellar travel between Venus, Earth and Mars has become commonplace. Dozens of interstellar travel companies of all sizes have provided humans with cheap interstellar travel services: 5 yuan per 10,000 kilometers! Each space travel service fee is 1,000 yuan. If calculated based on the current orbits of Earth and Venus, the shortest distance is 25 million kilometers; even if it is added to food, drink and other travel expenses, 30,000 yuan can take a round trip! - This is the idea of ​​a passenger!

What? Why did I spend 50,000 yuan on the round trip just for air tickets? The customer angrily questioned the waiter!

Waiter: The planet also needs to move. The shortest distance is 25 million kilometers, but the actual flight distance of the spacecraft is 38 million kilometers; and the return distance is as high as 58 million kilometers. Speaking of this, the waiter looked helpless: We can't let the planet stop and not move!

Customer: I no longer believe in advertising...

Waiter: It's not an advertisement error. We have already made it clear that the distance between Venus and Earth is closest at this time; but the spacecraft must chase the moving Earth during flight, and when returning, they must chase the moving Venus, so the actual distance must be much larger. Besides, your price calculation is calculated based on your calculation method inside the planet, not according to interstellar standards, and of course there is a deviation.

With the development of technology, star tourism has become commonplace. And such things continue to happen. Many people still have not changed their minds - it is because technology is developing too fast, and it is a bit too fast! People have not yet had time to adapt to the relationship between relatively static ground and permanently moving space. Many computing units are still calculating according to the rules of the ground.

But this year, society has begun to be much calmer, to be precise, there is a kind of depression!

Because today is the time when the signal return of the whale sign signal in the calculation - the specific time cannot be accurately estimated. After all, the starry sky is also constantly moving. And there are too many mystery in the starry sky. The distance of 12 light-years. The signal transmission difference is quite normal. The more humans study the starry sky, the more they can feel the mystery of the starry sky. For example, under a high-power telescope, the stars in the starry sky do not exist continuously. Some stars will disappear out of thin air for a while and reappear after a period of time.

It is because there is a kind of black hole partition effect in the starry sky: maybe there is a black hole in the middle between a certain planet and the earth, so we can't see the star; or some non-luminous nebula in the starry sky, etc. In fact, after modern scientific measurement and calculation, the mass of the luminous object in the universe is only 2~3% of the mass of the entire universe! And the light that human eyes can see is only 4% of all light waves! Therefore, the task of studying the universe is really a long way to go!

At the beginning of this year, the War spacecraft undertaken by the Empire was finally completed. This spacecraft was built by more than a dozen large groups of the Empire to expedition Greze, a life planet 20 light years away. For this goal, the group companies of the Empire have also gone crazy over the years! Under the surveillance of the Empire, they "attracted" 1,000 Jindan stage masters and several ordinary practitioners in the Void Dan stage; at the same time, they are also cultivating some practitioners. In addition, each mecha costs 30,000 to 20 million yuan to purchase 30,000 military war mechas from the Empire. These mechas range from ten meters to 100 meters in size, and there are 200,000 fighter jets!

In addition, the Empire was entrusted to train 500,000 real soldiers and ten thousand non-commissioned officers of all sizes on their behalf.

For their own dreams, these group companies have thrown out 80% of the wealth accumulated over nearly a hundred years! It can no longer be described as crazy. Moreover, in order to save costs, the spacecraft is built using the technology of the Imperial Hope spacecraft - mature technology!

The Empire did not simply copy spacecraft, but built and studied at the same time, so it cost a lot and took a long time! But these merchants were not like this. They directly adopted the mature second-generation spacecraft technology, so they did not need to invest a lot of money in research or spend a lot of time on public relations - just copy it simply.

This will directly reduce the cost of the spacecraft by 40%, and the construction time will be directly reduced to within ten years!

However, not all new technologies have not been adopted, and some low-priced new technologies are still needed; especially the energy protection layer technology of the Monster Group, which has achieved initially good results in ten years of research and development, and can achieve the effect of defending against sniper rifles and bullets.

In addition, the war weapons in the spacecraft cannot be reduced, which is also a huge expense. Many of them have adopted new technologies, and some attack weapons are terrifying.

The final spacecraft built is 180 kilometers long, with a diameter of 55 kilometers and a diameter of 300 kilometers. It uses 10 million Gentian No. 2 engines and 10 million Dragon Wing No. 1 engines, with a maximum acceleration capacity of 5 meters/sec^2 and a maximum deceleration of 4.3 meters/sec^2 - mainly the function of the solar sail.

Now the War spacecraft is ready to go, and will arrange to set off immediately after receiving the signal from the whale sign.

In addition, after ten years of continuous discussion, exploration, technical research, etc. on the earth, the determination to go to Barnard planet has been further determined; in addition, the Guangming spacecraft has been improved a lot, and two 10-kilometer-length sub-cabins have been added. The sub-cabins store electrolytic hydrogen and oxygen, which is a cheap, environmentally friendly, and efficient energy storage and combustion method. It is also a very traditional and very mature spacecraft driving technology. With the sub-cabin, the power of the Guangming spacecraft actually exceeds the power of the war!

Of course, power cannot be regarded as the only standard of spacecraft. Survival ability, armed forces, internal environmental construction, etc. are all big problems! The imperial spacecraft are all the kind that can survive in the universe for hundreds of years - at least in theory. The nuclear energy inside is exhausted. The solar sails can also be used to capture solar energy, so that the ecology inside the spacecraft can barely maintain.

But similarly, the Earth's Light spacecraft is also waiting for information from the whale constellation. The information of an outer star system is conducive to humans' objective judgment and evaluation of the outer star system. To be honest, according to observations, people were surprised to find that the solar system is too rich! There are countless celestial bodies around to provide resources for humans! In contrast, some stellar systems only have one lonely star and a few fragments! Such stellar systems do not even have the value of transformation - basic rocks are not enough.

However, another major event is about to happen this year: After rigorous exploration and calculation, the Empire actually prepared to build 6 life planets in the asteroid belt!

It turns out that the asteroid belt is very empty, with a distance of 550 million kilometers between Mars and Jupiter, almost 3.7 times the distance between the Earth and the Sun. Even the former asteroid belt is as wide as 220 million kilometers and is divided into two layers.

Therefore, after strict calculations, the empire can arrange six planets within the asteroid belt! These six planets are combined in pairs, making them satellites and hovering each other; the distance between each pair of planets can be controlled at a distance of 420,000 kilometers.

Of course, in view of the natural light difference here in the asteroid belt, the Empire is preparing to learn from Mars' transformation technology to build a large number of reflectors in the orbit of Venus to provide sufficient light to these planets. Anyway, these reflector construction techniques are much simpler - compared to those reflectors that can be used to push spacecraft forward, it is simple like building blocks.

However, this plan has not yet begun to be implemented. We have to wait until the Empire's War spacecraft and the Republic's Light spacecraft leave. After all, building a planet out of thin air is not only a challenge to the Empire's technology, but also an impact on the gravitational balance of the solar system. If it has an impact during the advancement of the spacecraft, the consequences may be catastrophic. Even if this impact can be theoretically negligible!

Therefore, the Empire will only start to build such a planet after the spacecraft has completely left.

Everything is waiting for a signal from 12 light years away to return!

From the 107th year of entering the Imperial calendar, that is, at the end of 2162 AD, people began to look forward to the information of the first batch of human heroes.

Although, people are full of confidence!

Although, people are full of passion!

Although the earth's technology is developed!

But... everything cannot escape a "in case"!

The imperial citizens who had relatives on an expedition even refreshed the imperial official website every day.

It's really broken fingers...f5 is rotten...

The entire human society seemed to be stuck, just waiting for the Warriors' signal to come back!

Living up to everyone's expectations, the first wave of signals came out! That was the clear images of whale constellations taken by the spacecraft, and even the space probe launched by the civilization here!

The alien civilization's universe probe? This made many people feel worried... It seems that this alien civilization does not have no ability to resist at all!
Chapter completed!
