In the following days, Song Jiancheng and his family were happily playing in space, while observing the space farm in the space city, after all, this is the main purpose of his visit.

The family stayed in Space City for more than a week, and Song Jiancheng also had a certain understanding of space agriculture, but now was not the time to make a decision directly.

Although after this period of investigation, he has great confidence in investing in space agriculture, after all, as human beings enter the interstellar age, people's life expectancy is getting longer and higher, and the demand for various foods will be higher and higher in the future, especially the demand for high-energy food.

But with the rapid expansion of the human population, the land on the earth is limited, if there is no new source of food, the Ming Empire will definitely introduce a population restriction policy, after all, when the population swells to a certain extent, it can not be increased and increased will lead to the collapse of the empire, which must be what the Ming Empire does not want to see.

But in addition to the introduction of population restriction policies, there is also a way to obtain additional land to increase the source of food, and this source of the Ming Empire set its sights on the vast space, after all, compared with the vast space, both the earth and the moon are too small, only by looking down on the vast space can human beings achieve greater development.

In the future, no matter how much the population swells, the empire will not collapse because of food problems.

Although there are certain dangers in investing in space agriculture, after this period of investigation, he found that this is not the case, and the main source of threats to space agriculture is space meteorites and solar wind.

What's more, human science and technology have developed to the present, especially in the past ten years, the early warning means of various threats in space have become more and more advanced, so now human beings have a complete early warning means for the solar wind and meteorites, not to mention that in fact, the space farm itself also has a certain defensive ability and attack ability, although the power of these offensive weapons is not too great, and there is not much threat to large meteorites, but the power of those small meteorites is enough.

What's more, those space farms themselves can also be moved, when the threat comes, these space farms can rely on their own power systems to avoid dangerous areas, not to mention that those large meteorites will be destroyed by the military immediately after entering the space city for a thousand kilometers, so in fact, the threat of large meteorites to the farm is not as big as imagined.

Therefore, through the investigation in the past few days, it has been found that it is actually a very cost-effective thing to invest in space agriculture.

What's more, the second space city of mankind has begun to be built, and the scale is twice as large as his current project, such a huge space city, in the future, the number of people who work, live and research in it will definitely exceed one space city, so the consumption of food will definitely exceed several times that of the first space city, so you can imagine how much food all the people in the first space city and the second space city will consume every day, and if all these foods are provided by the earth, Then not to mention the cost of transportation alone is an astronomical amount, in addition to various costs.

So he has a lot of confidence in space agriculture, and after he discussed it with his wife in the industry, his wife also agreed with his idea very much, and also encouraged him to invest in space agriculture, after all, the land resources on the earth are very limited, and the number of human beings such as the population will only increase, and now the big ass has limited their right to buy land for these big landowners, so he will only have less and less land on the earth in the future.

So after they finished investigating space agriculture, he and his family embarked on a spacecraft to the moon together, after all, they want to investigate not only the space city, but also the moon, after all, the environment of the moon is much better than the space city, although it cannot be compared with the earth, but this is already very good.

And now the number of people on the moon is also very large, and the food consumed every day is also a lot, and compared to the space farm, the investment in the moon farm is much smaller, and the benefits are also very large, although he is now a famous big landowner in the Ming Empire, and there is no shortage of money in his hands, but he can save a little less, after all, such a huge amount of investment makes her have to be careful just in case.

So their family set foot on the spaceship to the moon, although the space city to the moon also has an interstellar train sailing, but compared to the spaceship, the safety of the interstellar train is not too high, after all, navigating in the universe and on the earth's orbit are completely different things, there are too many threats to face in the interstellar navigation, just relying on the weak armor on the train, it is really not enough, not to mention that when encountering danger, the flexibility of the interstellar train is not high, this is not a design problem, It's that a shape like an interstellar train is really not suitable for navigating through space.

So compared to the interstellar train, the spaceship is much safer, after all, although many spaceships are not good-looking in appearance, but his defense is much stronger than the weak train, even if it is the smallest spaceship, its defense is several times more than the train, and some can even exceed more than ten times, and the spaceship is very flexible in the universe, and most of the spaceships are attacking, so that the spaceship can avoid a lot of dangers in the universe, Especially large spaceships.

Therefore, if it is not necessary in space, everyone is still willing to take a spaceship.

Song Jiancheng and his family soon boarded the spaceship closest to their place, this is a medium-sized passenger spaceship, about 150 meters long, looking at the heavy armor of the spaceship, and the hideous artillery installed on the bow of the spacecraft, he felt a sense of security coming to him, after all, the interstellar train does not have such equipment, although the comfort of the interstellar train is much higher than that of the spaceship, but for a rich man like him, safety is still the most important.

But in fact, the comfort of the spaceship is also very good, and it is very luxurious, and even during the flight of the spaceship, the staff on the ship also allow them to move around at will, but during the take-off and landing of the spacecraft, it is true that those who cannot move around at will must sit on the seat and fasten their seat belts, after all, during the take-off and landing of the spacecraft, the spacecraft will bring a very large load during acceleration and deceleration, although compared to the combat spaceship, the acceleration of the spacecraft operated by the passenger is much lighter, but if the personnel on the ship do not pay attention to the safety situation, it is still very easy to get into trouble.
