After more than a year of sailing, the Advance has finally returned to Earth.

Xiang Qian's departure this time adds up to less than four years, so the upgrading and transformation of the Earth's outer space defense circle has not yet been completed. Everywhere in the galaxy, you can see large transport ships and multi-purpose industrial machines in space, these unmanned mechanical equipment that are completely controlled by computers, never stop working.

Compared to when he left, now within 5o thousand kilometers of the earth's outer space, it has been occupied by various space factories, and countless satellite fortresses reflect the light of the stars under the sunlight.

When the Star landed at the small spaceship berth in the Earth Federation Government Building, the entire Earth Federation came out to greet them.

Xiang Gan's parents stood at the front, and when they saw Xiang Gan appear, they greeted him as soon as possible.

In the past few years since Xiang Qian left the earth, although there was also contact, but in the vast universe, no one dared to say whether they would encounter any danger, so they looked forward to Xiang Gan's early return every day in the past few years. But they also understood the responsibility on Xiang Qian's shoulders, even if they were worried and missed, they didn't reveal anything in every call, they just told Xiang Qian that they were okay together, don't worry.

"Mom, make something delicious in the evening, I'll go home and eat."

"Okay, let's go back and prepare now, and make your favorite food."

After casually talking to his parents, Xiang Qian asked Condensation to take his parents home, and he also had to go to a meeting with the high-level officials of the Earth Federation to learn in detail about the development of human beings in the past four years.

In the past few years that Xiang Qian has been away from the earth, most of the information he has learned about the starry sky is whether the earth has encountered danger and has not caused major problems. As for some details, he didn't ask about them.

"Xiao Qian, are you encountering any difficulties outside? Is there something big about it? Captain One asked in a low voice on his way to the conference room.

"No, it's just that this harvest is enough. There's no need to go on. Next is the beginning of the great construction of the earth, as long as the data I brought back this time is consumed, there will be no problem for human beings to break through the fourth-level civilization. Xiang Qian said with a smile.

"That's good, otherwise it's going to be a war after just a few years of stability, which is not good for Zhan."

"Well, now is not the time for war."

After arriving at the conference room, Xingkong began to report to Xiang Qian on the exhibition of human beings in the past four years.

Among them, the first line of defense of the stellar defense circle has been fully arranged, and all the manufacturing materials of the satellite fortress are level 4 technology materials. At the same time, the previously produced satellite fortresses were not wasted, and all of them were replenished to the third line of defense.

The construction of the second line of defense is intensifying. It is expected to be completed in its entirety within three years, and even if dozens of pioneer civilizations attack the earth, it will be much better than breaking the second line of defense of millions of satellite fortresses, not including the defenses on the five rocky planets.

It can be said that when this line of defense is completed, there will be no need to worry about the safety of humanity in the Big Magellanic system.

Except for the construction of the defense line, all the other resources of mankind are inclined to the field of scientific research, and now a random person is pulled out of the earth, basically at the level of the previous graduate students of human beings. And young people under the age of 5o, each of them has the level of a previous doctoral student. That's the minimum standard.

The total human population on the earth is now 11.7 billion, and this is because the mortality rate of human beings has been reduced to the level of 1 in 10,000, with the spread of cell division drugs, except for the people who die accidentally. There are no examples of natural deaths. In addition, most of the human population has become evolutionaries, even ordinary evolutionaries with no special abilities, on the basis of genetic level improvement. Life has also reached 5ooo years.

In this way, the genetic hierarchy of the newborn does not become an evolutionary, whether in terms of learning ability or other aspects. Also over the previous humans. Coupled with a good education, the proportion of human scientists is increasing year by year.

In the absence of internal consumption, waste of resources. The exhibition of humanity has passed through the imagination of the past. Now all scientific research materials can be found on the Internet, and everyone can participate in research and provide opinions.

It can be said that every topic of human research is a collection of the wisdom of human beings as a whole to study and tackle key problems. In the case of sufficient materials, scientists are not afraid of waste, and every feasible opinion will be tested, such scientific research efficiency is simply terrifying, and at the same time, the hidden genius of the people can be revealed.

As for the battleship, it wasn't made at all. According to Xiang Qian's instructions before he got up, he only studied and did not build. All the ships that have been researched are put to the test in the endless starry sky, and players can also give their opinions.

With the current defense force of the earth, it is useless to have so many warships, all the factories are producing transport ships every day, how can there be time to produce warships. Moreover, these warships will basically be eliminated in a few years after they are produced, which is a complete waste of time and resources, and has no practical significance and use.

The current earth is not ready to attack other civilizations, and if you protect yourself, the existing defense system and the previous warships are enough, and there is no need for so many warships at all.

Therefore, in the past few years since Xiang Gan left, not a single battleship was produced, all the ships produced by the factory every day were transport ships and industrial aircraft, and a lot of scientific exploration spacecraft were produced. However, as long as humans want to produce warships, and all factories are open at the same time, there is no need for equipment manufacturers to participate, and humans can produce 1ooo warships in a day.

It took a full two hours for Xiang Qian to figure out the situation of the human race during his absence.

"Well, let's do it first, everything is going well at the moment, and there is no need to change much. However, I will personally manage the problems of scientific research today, and the rest will be implemented according to the goals set before, and at the same time, everyone has worked hard all these years, so I will come here today if I have nothing to do, and the meeting will be dismissed. Xiang Qian said.

Before leaving the conference room, Xiang Qian had a chill with a few acquaintances for a while, and then hurriedly returned home.

In the evening, after Xiang Qian finished eating at home, chatted with his parents for a while, and then returned to the room and asked Xingkong to sort out the information of those who had been engaged in small actions in the past few years since he left.

In fact, in the process of returning home, Xiang Qian deliberately did not have contact with the earth for a period of time, not even with his parents. At the same time, after losing contact, he also deliberately said that he was going to a dangerous place next.

In this way, Xiang Qian has not been in contact with the earth for a whole year, and has been letting the stars monitor the entire human race, the purpose is to find out which people have thoughts about the Earth Federation.

As a result, there are quite a lot of people who have no ideas and ideas, but all the armies of the Earth Federation are under the control of Xiang Qian, and the mastermind of the Federation is also the starry sky, and those who have any ideas have nothing to do at all. Some of them also hope that other civilized races will attack the earth, so that they will have a chance in a state of war.

But unfortunately, in the past few years, no civilization has attacked the earth, and their ideas have been frustrated.

"Starry Sky, let the biochemical warriors do it, and arrest all of these people." After reading all the information, Xiang Qian said with a sneer.

"Okay, boss."

A storm broke out on the night of Xiang Gan's return, and many people sneered after learning about this situation. Many people know what those people think, but before Xiang Qian comes back, no one cares about them, but as long as the brain is not faint, they will not come into contact with them.

Now that Xiang Qian came back, those people were really unlucky, and they didn't want to think about what the current situation was on the earth. For people who can't see the form clearly, even those who have something in their hearts, they won't contact their pig teammates, because it's all about looking for death.

Xiang Qian didn't care about the next thing, and in front of the information provided by the starry sky, any quibbling was useless. According to the laws of the Earth Federation, no one can escape how to be sentenced.

Early the next morning, Xiang Qian and Condensation finished breakfast and came to the scientific research building, where they would discuss with all scientists the direction of the future scientific and technological system of mankind for a period of time in the future. (To be continued!)
