Wei Feng also felt the same way about the words Chu Hai said. If human civilization was at its peak in the previous stage, it is indeed on a downward trend now.

Human civilization has already experienced a peak period, and that peak period was hundreds of years ago, when fossil fuels supported the prosperity of human civilization. But the good times were short-lived, and as the population grew and fossil fuels were depleted, the peak passed. It was not until the mastery of controlled nuclear fusion technology that human civilization once again ushered in a new peak. But now the population has once again begun to explode......

Wei Feng believes that there are two indicators to measure whether human civilization is at its peak, one is the total amount of resources that can be controlled, and the other is the total number of people. If the total population is fixed, the more resources there are, the more abundant the material per capita. If the total amount of resources is fixed, the lower the total population, the more abundant the material per capita.

So now there is a key question, is the ratio between the number of human civilization's population and the total amount of resources at its disposal really out of balance?

If from a macro point of view, the energy in the solar system can actually be regarded as infinite, because Jupiter, Saturn, Uranus, Neptune these four planets contain almost endless hydrogen energy, according to common sense, since human civilization has mastered the technology of controlled nuclear fusion, then human civilization should no longer be bothered by energy. But don't forget that there is also a cost to the extraction of energy, and the scale of the extraction of energy cannot be expanded indefinitely, it always has an upper limit, after reaching this upper limit. It will be difficult for human civilization to increase its energy output again.

Meanwhile. There are other constraints as well. For example, the limitation of food production. For example, the restriction of living space and so on. It is precisely because of these many constraints that the total number of people that can be carried by the entire solar system is limited, and after the population reaches a certain level, if we want to maintain the per capita material needs without decreasing, then there is only one way out - colonizing aliens.

But if you want to colonize aliens, you will encounter the problem of "dead knots". How to break this dead knot? Wei Feng didn't know.

Just like Chu Hai said, the time traveler has a unique advantage in the matter of watching the trend of human civilization. Through Chu Hai's description, Wei Feng also faintly felt a little bit of a crisis brewing. Wei Feng knew that these things that appeared in human civilization now were just the beginning. It will inevitably continue to develop and get worse. If there has been no technological breakthrough, then ...... Human civilization could return to chaos or even war.

This is due to the trend of human development, which is not subject to the power of the individual. Even if there is a genius head in human civilization, as long as he cannot bring about a technological breakthrough, then he will not be able to reverse this trend.

Wei Feng let out a long sigh and gave up his contemplation. Wei Feng felt that there was already a noose around the neck of human civilization at this moment, and it was quietly tightening as time slowly slipped away. If only human civilization could find a way to open the noose before it hangs itself. Then human civilization can be reborn, if it can't be found. It can only be like the many extraterrestrial civilizations that may exist in speculation and have perished before leaving the home galaxy, quietly disappearing into this dark and cold universe, and cannot send out a cry of its own to the universe until death.

Wei Feng's heart suddenly moved. Because at this time, Wei Feng thought of the fragment of an unknown civilization that he had discovered.

"It is very likely that this unknown civilization has opened the knot and found a way to travel at high speeds, even faster than the speed of light. If only more relics could be obtained...... Maybe we can find enough technology to save our civilization. If this is the case, human civilization will not have to be bothered by this dead knot. ”

Wei Feng knew that all these ideas about the future fate of human civilization were just speculation, and no one could verify the authenticity of these ideas except time. Even, except for Wei Feng Chuhai and others, people living in the solar system normally would not have such thoughts. However, the sensitivity of being a time traveler made Wei Feng agree with these speculations from the bottom of his heart.

"Because we are time travelers, we can detect these trends. You're not, so you don't perceive it. ”

"Now that we have detected this trend in advance, we have an obligation to do something as a member of human civilization." Wei Feng thought silently, "Do my best to search for the relics of alien civilizations, search for the technological inheritance that they may leave here, so as to help human civilization open this dead knot as easily as possible, this is what I can do." ”

"Leaf fall." Wei Feng called out. Ye Luo's unique neutral voice immediately appeared in Wei Feng's ears: "Captain, what do you command?" ”

Wei Feng said: "From now on, I will grant you additional permission to fine-tune the route. In addition to the amount of fuel required to ensure the necessary acceleration and deceleration of the outbound and return journeys, you are free to allocate the rest of the fuel. These fuels are used ...... If you spot a suspicious target in the distance, you can adjust your course to get a closer look at the target. ”

"At the same time, four probes are selected and modified, and then they are launched to the left and right of the spacecraft, up and down, so that they maintain a relatively stationary motion with the spacecraft, so as to expand the detection field of the spacecraft."

There are probes in reserve in the Xinghai spacecraft, and these probes were originally intended to wait for Wei Feng to arrive in the South Gate II galaxy before activating them, but now Wei Feng has decided to activate them in advance.

"Okay Captain, may I ask, do these things need to be reported to the Earth? You have autonomy over these things, so you can decide for yourself if you want to report to Earth. ”

Wei Feng hesitated slightly, and then replied, "Don't report to the Earth side. It's my personal behavior. ”

Wei Feng can be sure that the earth side must not agree with his speculation, so he will definitely not agree with these things he has done. In that case, it's better not to tell the Earth side at all, anyway, they don't know what they did here.

"Okay, you need to complete the transformation of the detector, and I don't have the ability." Ye Luo said.

"No problem." Wei Feng immediately agreed.

In the course of more than 20 years of training, Wei Feng has mastered these skills. Something like retrofitting a detector is still up to the task. As a result, in addition to the daily recovery training, replacing broken parts, and eliminating the bugs accumulated in the process of leaf fall, Weifeng has another job.

The modification of the probes was completed a month and a half later, and they were launched by Weifeng. Compared to the Xinghai spacecraft, their relative speed is very slow, only about ten kilometers per second. It would take about a year and a half to fly to the designated position at this speed, which may seem like a long time, but it is nothing for Weifeng. Wei Feng has nothing else, but there is plenty of time.

Once they reach their designated position, they slow down and remain relatively stationary with the Star Ocean spacecraft. The Xinghai spacecraft is moving at a speed of 3,000 kilometers per second, and they are maintaining a relative stationary position with the spacecraft, that is, they are also moving at a speed of 3,000 kilometers per second. This is inertial navigation, which does not require additional fuel, but the detection instruments equipped on them can expand the field of vision of the Xinghai spacecraft several times. In this way, the possibility of discovering the remains of alien civilizations is naturally greatly increased.

"Captain, I'll fix the location of the probe in the future, and now, it's time for you to hibernate." One day two months later, Ye Luo once again calmly issued a hibernation notice to Wei Feng.

"Okay." Wei Feng nodded, and after some preparations, he once again lay down in the hibernation pod.

The same process was still the same, and the Star Ocean spacecraft was once again back in cold darkness. What is different from the previous one is that in the four directions of the spacecraft, left and right, up and down, there are four more small but powerful probes accompanying the Xinghai spacecraft.

Time passed slowly like this, until one day after that, the life support system was opened, the functional systems were opened, and then the hibernation cabin was opened, and Wei Feng opened his eyes again.

Every hibernation was like dying and coming back to life, and every time Wei Feng woke up, he felt as if he had been asleep for 10,000 years. But this time it felt a little different. I don't know why, Wei Feng felt that the time he had been asleep this time seemed to be a bit short.

"Ye Luo, has ten years passed?" After regaining his ability to think, Wei Feng asked Ye Luo this question.

"No, Captain, it's only been six years since you last slumbered." Ye Luo replied, "The reason why I woke you up in advance is because I encountered an unexpected situation, and according to your settings, I don't have the authority to deal with this incident on my own. ”

"Emergency?" Wei Feng immediately asked, "What happened to you?" ”

"At a distance of 700 million kilometers in a straight line from the spacecraft and a vertical distance of 400 million kilometers from the channel, I received an unknown signal of unknown meaning." Ye Luo calmly replied, "If we maintain our current course, we will be 400 million kilometers away from the signal source in about two days and four hours. How do you plan to respond to this incident? (To be continued......)
