Chu Hai's letter to Wei Feng described: "The energy harvesting instruments manufactured by several major mineral resource companies cover almost the entire atmosphere of Jupiter and Saturn, and the long-term exploitation of hydrogen and helium has almost changed the atmosphere structure of these two planets. I can't fill it up anyway. According to the survey report of the Ministry of Scientific Research, the average daily demand for fusion energy on Mercury alone has reached the level of tens of billions of tons, and the average daily demand for fusion energy in the agricultural belt around Venus has exceeded 5 billion tons. ”

"Among the several habitable planets and moons, the Earth is undoubtedly the number one, with air that can be freely breathed without treatment, and countless beautiful views. Therefore, the earth was the first to enter the state of full load. Today, there are more than 50 billion people living on Earth, and more than 20 billion people on Mars. In addition to the two most important habitable planets, the large number of living islands in the inner solar system is home to 10 billion people. ”

"These three places are home to almost all of the elite groups of human civilization, because of the increase in the cost of living and the increasing competition, a large number of civilians and poor people have to migrate to the outer solar system, and the moons of Jupiter, Saturn, Uranus, and Neptune are all developed to support as many people as possible. But the farther away from the sun, the harsher the living conditions. They also do the heaviest labor, but the wealth they create is concentrated in the inner solar system and cannot be used to improve their living conditions. ”

"When the energy output reaches the ceiling. Governments will inevitably demand that priority be given to securing the energy needs of Earth, Mars, and the living circles of space islands. And this. It will further reduce the quality of life of the population of the outer solar system, which accounts for 70% of the total population. Wei Feng, do you know, this has become an irresolvable contradiction, and no matter how hard the government tries, it can only alleviate the contradiction in the end, but cannot eliminate it. This contradiction will one day erupt. ”

"Our solar system has truly become an island in the middle of this boundless sea of stars. The resource output of the island is limited, but the population is increasing all the time. We urgently need to get out of this isolated island and demand a wider continent. We are looking for more planets and energy sources, but our technology has never been able to make breakthroughs. ”

Wei Feng left the laptop and walked to the ship's porthole. Looking at the boundless darkness outside the window, Wei Feng felt a sense of loss in his heart.

This result had long been expected by Wei Feng, but when this result really appeared, Wei Feng was still a little difficult to accept. After all, it is my hometown, and it is the place where I will go back one day.

Standing in front of the porthole for a long time, Wei Feng let out a long sigh, picked up the tools in his hand again, and began to repair the ship.

More than a hundred years have passed. During this time, the Star Ocean spacecraft did not suffer any major failures. The leaf drop is also generally working well. It's just that all kinds of small parts are damaged and bugs appear more and more frequently. This meant that Wei Feng had to devote more time and energy to the maintenance of the spacecraft.

After all, this is an old spaceship that has been working for more than a hundred years...... In the solar system, there must be no instrument that has the opportunity to work continuously for a hundred years.

Since passing by the unknown alien civilization device, Wei Feng has never found any possible alien civilization creation. Not only that, but even the natural objects that exist here have not been encountered. This is the area where the Oort cloud is speculated, but the emptiness here is beyond Wei Feng's imagination.

Although Weifeng did not observe any macroscopic objects here, this does not mean that the existence of the Oort cloud has been overturned. The estimated total mass of the Oort cloud is not comparable to the mass of the Earth, and if these masses are scattered into a disk with a total length of more than six light-years, the thinner material here can be imagined. It's normal to see nothing here.

Wei Feng calmly drove out of the Oort Cloud region and completely left the solar system. This was originally a moment of great historical significance, but Wei Feng did not feel the slightest excitement in his heart, and some were just lonely in the bone marrow.

The two-way communication between here and the Earth has been delayed for up to two years, but because of the existence of several large antennas in the solar system, Weifeng can still maintain contact with the Earth. It's just that this connection is getting weaker and weaker, when they were close at the beginning, Chu Hai and Wei Feng often transmitted some video files, and then they could only transmit sound files, and now, they can only transmit text messages.

I'm afraid that after a little further away, the Star Ocean spacecraft will lose the ability to send information to the Earth. However, according to calculations, the ability of the Xinghai spacecraft to receive information from the Earth will not be lost, and even if it finally reaches the South Gate Two Galaxy, the information sent by the Earth can also be received by the Xinghai spacecraft.

Another decade has passed, and Wei Feng woke up again as promised. As Wei Feng expected, there were still letters from the Earth. Perhaps because the government has forgotten about the Lonely Island Project, the letters sent from Earth have all been written by the Time Traveler team for decades, and the government has not paid any attention to them, neither giving instructions nor responding to some of Weifeng's reports.

Wei Feng thought that the human world had probably forgotten about the existence of the Time Traveler team. Being forgotten is not a good feeling, but Wei Feng's heart did not make waves because of it. Because Wei Feng knew that being forgotten was originally the fate of the Time Traveler team.

"Wei Feng, I'm sorry that this time I told you still bad news." The "dead knot" theory was also confirmed. Before we go out of the solar system, we may not be able to make any further progress in the science and technology of human civilization. ”

"I have heard that the current administration has deliberately responded to the dead knot theory, and that the head of state intends to concentrate its efforts on promoting large-scale exploration of the outer solar system in order to seek scientific and technological progress. But we are not optimistic about the future of this plan. Because the contradictions within human civilization have become very prominent, it is easy to cause social unrest if it expends huge resources to explore the outer solar system. Let's hope that our human civilization is lucky enough to get enough technology before society finally collapses. ”

"Well, by the way, it is likely that many mission orders will be sent here after a while, and the scientific research department may want you to do some preliminary space exploration to pave the way for the subsequent large-scale operations." (To be continued......)

PS: Today's state is really bad, I really can't write it, so that's all...... Rest for the night and should be able to recover tomorrow.
