There is a blue planet in the direction of Cygnus and Lyra, called Kepler-22B, which is about 3 times the size of the Earth, and the gravity and atmospheric pressure are about 0.8 times that of the Earth, and the year here is equivalent to 290 days of the Earth due to the difference between the stars around it and the Earth's Sun. From a distance in space, the planet looks very similar to Earth, but the two planets are 600 light-years apart.

In 2412, the earth was no longer suitable for human habitation due to various environmental changes. Seven Arks set off from the earth, as pioneers, carrying part of the earth's human beings, a large amount of nuclear energy, high-tech and other related resources, after ups and downs to Kepler-22B to move, since then this renamed - New Blue Star, expressing nostalgia for the former earth.

Before leaving, these humans made an oath and promise that once they developed well in New Bluestar, they would return to Earth and lead the rest of the humans to move in, but this made the humans on Earth wait for nearly a thousand years!

After these people came to New Blue Star, they found that this is a planet with highly evolved plants, native plants contain strong corrosive sap, and in such an extreme environment, there are even parasitic bacteria that can swallow metals, so that many water sources are undrinkable, and the soil is very different from the earth, which is not suitable for planting, so the early development of human beings who have migrated here is very slow, and there are still quite a lot of human beings who rely on nutrient solutions to ensure physiological operation.

Based on the seven arks, it took hundreds of years to build seven city-states in several relatively inhospitable places. Creatures, especially humans, once they develop to a certain extent, will compare and compete with each other, and many of the humans in New Blue Star have forgotten their original oath for various reasons. The area where the Ark of the Seven City-States is located is an important area, which is strictly guarded, and it is the birthplace of various scientific and technological techniques, and a large number of scientific and technological talents are busy in it.

"I am a small farmer with strong planting ability, and I want to take care of my small field very beautifully; I'm a small farmer, and I planted radishes and flowers! ”

On September 17, 3413, Xia Long tended his farm in a large warehouse in City-State No. 1, humming a tune from thousands of years ago, and gnawing a radish clean, and the soil of the countryside was all preserved from the earth thousands of years ago.

This warehouse is also Xia Long's residence, not far from Ark 1, Xia Long's mission is to grow agricultural products, and he is accompanied by a humanoid intelligent robot named Tulip, who looks like a beautiful little girl of 16 years old, who was made 3 years ago. When the produce matures naturally, the tulips exploit a large amount of the fruits of Charlon's labor and give them to a mysterious employer to eat.

Seeing Xia Long stealing food, Tulip came over and said coldly: "Xia Long, if you want to steal the master's food again, I will let the master, that is, your employer, exempt you from all your benefits for this month!" "Xia Long admires this employer very much, such a large warehouse, except for his own land, everything else is used for planting, can one person eat? This warehouse is not very peaceful, since a few years ago when I moved here, Xia Long can always hear some strange noises in his sleep, and wake himself up.

Xia Long's ancestral home is from the east of the earth, a young man with yellow skin, black eyes and black hair, 20 years old, most of his relatives left suddenly in his thirties because of the unsuitable environment in New Zealand, without any premonition, only a dying grandfather remains, so Xia Long is a thousand-year-old single biography!

With the current science and technology, Xia Long's relatives would not have left so suddenly, but after moving to New Blue Star, humans did not adapt to this strange environment. Although it can survive, there are differences between the air pressure, atmospheric composition, and gravity of the earth, and it is easy for human beings who have been breeding on the earth for generations to have sudden potential genetic mutations (hereinafter referred to as abnormal diseases) and then die.

This situation has only been improved in recent years, led by the No. 1 city-state, united with other city-states, using science and technology, consuming a lot of energy, forming a kind of barrier outside the city-state, so that the internal gravity, air pressure and many other factors reach the same level as the earth, and the barrier also has a certain defensive effect.

A small stereoscopic screen in the warehouse played the news, and Xia Long listened to it with relish. The upper echelons of the seven city-states formed two factions, one was the Regressionists, who advocated returning to Earth as soon as possible; One is the renunciation faction, which advocates abandoning the earth, and from the current trend, the return faction is very difficult.

It took a thousand years to build a city-state, and the barrier construction technique was used to create an environment similar to that of the earth, so you can imagine how difficult it was for humans to move to New Blue Star at that time. Don't simply think that the returnees are vowed thousands of years ago, but more about getting a long and healthier life. A temperature difference of one degree can make some creatures unable to produce or even survive, and when they first came to New Zealand, human beings were directly exposed to the uncomfortable environment to barely survive, and under this premise, some genetic techniques were used to make human beings survive better, which is also quite resource-intensive.

Thousands of years of abnormal evolution have put the humans of New Blue Star in a very embarrassing state, and the sudden departure of Xia Long's relatives at a young age is an example. The returnees hope to extract the genes of the earthlings after returning to the earth, or simply raise them in captivity to treat themselves for various diseases caused by potential genetic mutations, and if they can't do it, they will use the organs of the earthlings as backups. If this situation cannot be effectively solved as soon as possible, I am afraid that in a few years, the humans of New Blue Star will be a new species, and they cannot be regarded as human beings in the traditional sense.

It's just that the earth is not something you can go back to, you need energy, and the immigrants from the earth took away a large number of nuclear energy reserves, which is enough to solve the nuclear contradictions on the earth.

If you want to go back now, in addition to energy, there are still two things missing: one is the progenitor particle, the first high-energy particle produced during the Big Bang, which is the expansion of this particle, forming space, which can be found in the core of some planets, but the energy is lost a lot; The second is element 147, which is produced by element synthesis.

The artificially discovered progenitor particles bombarded element 147 after the acceleration of the strong magnetic cyclone, and the new substance, Progenitor 147, was formed, which also had the effect of "expansion" and affected space. Although the energy is not as large as the Big Bang, as long as it is enough energy to reduce the distance between the Earth and New Zealand Star from 600 light-years to a normal time of several years, or millions of years if it were a normal interstellar journey. This is also the difficult reason for the returnees, the conditions are too harsh, and the progenitor particles have not been captured for thousands of years.

From Xia Long's name, it can be seen that his relatives belong to the regressionists, and the orientals of the earth have always had a complex of returning to their roots. The humans who first came to New Zealand were either Monopoly or people with special talents, such as scientists, senior maintenance workers, doctors, and so on.

At that time, Xia Long's ancestors came to many people, and they had always been a family of traditional Chinese medicine, and the ancestors who emigrated were either traditional Chinese medicine, horticultural experts, or botanists, anyway, they all dealt with flowers and plants.

It's just that these advantages are not enough for Xia Long's ancestors to live a good life in New Blue Star, if Xia Long's relatives have enough wealth, they can use scientific and technological means to continue to live, such as ideology, similar to hibernation to stay in a mecha, what you see and hear is transmitted to the user's brain in the form of a dream, and the reaction is completed by the mecha. It is said that there are some elders who have survived since they moved to New Blue Star and can be called monsters for thousands of years.

Xia Long, who has been passed down for thousands of years, is very pitiful, Xia Long was very young when his relatives left, and he couldn't learn a lot of family knowledge through them, so he could only be an interstellar farmer here, but fortunately, with the completion of the barrier techniques of various city-states, Xia Long had a chance to turn over.

The city-states were built in inhospitable areas, which were not suitable for cultivation, and the previous conditions did not allow it, even if they used the soil of the earth, and solution cultivation was not good, because the weight, the atmosphere and the earth were different, and it turned out that the agricultural products grown in this way were easy to produce abnormalities, and then affect the humans who had eaten them.

But now it's different, the barrier technique can properly resist all kinds of radiation, has a good strategic defense effect, and makes the internal environment similar to the earth, so that the agricultural products grown by Xia Long have no side effects. In New Blue Star, which is not rich in resources, it is the luxury of many people to be able to eat a bite of green pure natural agricultural products from their hometown earth, and the era of the gold price of cabbage has come!

It was a very miserable time, although the technology was highly developed, some basic resources were extremely scarce, such as food and water, even the high-ranking people of the city-state had to inject artificial nutrient solutions to maintain their lives, and the water source had to be filtered, which consumed the energy of the major city-states.

The convenience of work allows Xia Long to always find an opportunity to deduct some cabbage radishes that should belong to his employer. Looking at some rotten and moldy vegetables, Xia Long felt a little distressed, they were all raised by himself with a hoe and a handful of sweat, can't they ripen for a few days?

Xia Long had a calculation in his heart, and was going to secretly take out some agricultural products to sell them on the black market on the outskirts of the No. 1 city-state in a few days, and then buy some technological products to let his grandfather live for a while longer, as for the ideology-driven mecha, Xia Long didn't dare to imagine it, unless he fired his employer and took all the agricultural products in a warehouse to auction!

At this moment, the screen of the warehouse suddenly changed the picture, and in space, a small spaceship emitted a dazzling light behind it, waving its solar panel wings, adjusting its speed and direction, and heading towards New Blue Star.

The narrator said with some excitement: "Now the news from the top of the New Blue has just been inserted, the 'Search' spacecraft has lasted 14 years, and it will not be long before it will return to the arms of the New Blue Star, I personally suggest that you guess, will this spacecraft find the Ancestral Particle?" ”

This is heavy news, especially for returnees, the "Search" set off from the planet Kepler-22E (later collectively referred to as Star E) to search for the presence of Archaeopteryx. It is a huge gaseous planet, large enough to hold thousands of New Blue Stars, somewhat similar to Jupiter in the solar system, acting as a vacuum cleaner, absorbing some meteorites and avoiding hitting New Blue Stars.

Assuming that the "Search Number" finds and carries back the Progenitor Particles on Star E, it will definitely make the 7 city-states compete with each other, and the best result is to use it back to Earth to solve the problem of foreign diseases; The worse ones were used to unify the 7 city-states; After the worst result, after unifying the 7 major city-states, he is still not satisfied, and he still wants to unify the earth!

For Xia Long, this news is just a gimmick to hype himself, just to sell his smuggled agricultural products at a good price, and maybe he can have a little spare money to transform his "Red Rabbit" spaceship. In a planet like New Bluestar, which is highly technologically advanced and worships speed, there is an unwritten rule that all residents must build a spaceship with their own hands before they reach adulthood, otherwise they will be despised.

Xia Long's "Red Rabbit" was also secretly smuggled the employer's agricultural products after the city-state had a barrier in the past few years, and it was completed with some expired materials in the black market and thrift market, barely reaching the standard of flying!
