The message left by Führer Keller let Wei Feng know a lot of things, but at the same time, it also left Wei Feng with some doubts. One of the most obvious is, who is the so-called wise old man? Why did he have the ability to sail the South Gate II galaxy hundreds of years before the implementation of the Lonely Island Project? Did he take the same hibernation voyage as he did? If not, how can his lifespan be explained? Or, the simplest question, all the doubts that exist in him can be summed up by this one doubt, that is, is he an earthling?

It seems that if you think of him as an alien with super technology, all the doubts that exist in him will be solved, but if so, there will also be some new doubts spread, that is, why does an alien with high technology have a connection with human civilization? What kind of attitude does he have towards human civilization? What is the purpose?

From Keller's narration, Wei Feng can probably be sure of one thing, that is, this so-called wise old man is quite kind to the human civilization on the earth, which can be seen from the fact that he reminded the human government about the dead knot in advance, and at the same time, Wei Feng has reason to believe that the mysterious flash he observed from the two galaxies of the South Gate was made by this so-called wise old man, and the purpose was to transmit some information to the earth, and this undoubtedly proved his good intentions.

With "goodwill" as a premise, many things become much clearer. The words "you can come here" seem to mean that he has some agreement with the government of human civilization on Earth before leaving, but there is one thing that needs to be noted. That is, Keller did not mention this in the information he had set aside. on this. Wei Feng has reason to think. This is in the passage of hundreds of years, in the constant change of heads, and the information about this agreement may be lost.

Führer Keller thinks that the wise old man is also gone because of the dead knot, because the Martian civilization may have left behind the key scientific data of the South Gate Two Galaxy, and Wei Feng also thinks the same. So, under this premise, what do the seven words "you can come" represent?

The first possibility. There may be some kind of danger in the South Gate Two Galaxy, and the wise old man has predicted it in advance, so he arrived at the South Gate Two Galaxy to solve this danger, and then the human civilization government can send forces to the South Gate Two Galaxy to retrieve those key scientific data that may exist.

The second possibility is that retrieving key scientific data requires certain preparations, and these preparations can only be solved by wise old men, so the preparations are made. After making it possible to "retrieve key scientific data", he sent back a message to the government of human civilization. You can send someone.

There are some other possibilities, but the probability is much lower, such as the wise old man needs to do something in the South Gate Two Galaxy, and he doesn't want these things to be noticed by the human civilization government. But Wei Feng was keenly aware of one thing, that is, no matter which possibility it was, it seemed to imply one thing, that is, the wise old man had no plans to return to the solar system and return to the earth in the future.

This inference casts a mysterious aura over this so-called wise old man, and at the same time adds a little credibility to the fact that "the wise old man is not an earthly life, but a member of an alien super technological civilization". Because it is obvious that if the wise old man is not an earthling, he will naturally not return to earth.

It is precisely because of this that the wise old man will ask the earth side to send someone to retrieve those things, instead of sending them back himself.

But there are contradictions in this inference. Because this inference is somewhat inconsistent with the scientific and technological strength mastered by the wise old man. There are two arguments for this contradiction, the first is that although the earthlings do not have the strength to communicate directly to the earth from the South Gate Two Galaxy, for example, according to the original plan, after Wei Feng arrives in the South Gate Two Galaxy, Wei Feng will completely lose the ability to send information to the solar system, because the distance is too far, but there is no way for the wise old man who has mastered super technology? If he had a way, why not send a signal directly to Earth to send that scientific data back? Why is it that even a simple message as "you can come here" should be conveyed through a gamma-ray flash that is extremely backward and extremely complex in comparison?

The second argument is that Keller said that the wise old man had set off hundreds of years ago, and the time when Wei Feng received the abnormal flash in the two galaxies of the South Gate was about three hundred years after he left the earth, and the sum of these two times was five or six hundred years, and Wei Feng had reason to believe that the wise old man had spent at least three or four hundred years on sailing in these five or six hundred years, so if this is calculated, the speed of the spaceship that the wise old man was riding should be not much different from that of the Xinghai spaceship. But in this case...... Doesn't this also mean that the wise old man has not mastered super technology far beyond human civilization?

Wei Feng thought about it, and there was no way to solve these contradictions. As a last resort, Wei Feng had no choice but to put these things in the back of his mind for the time being. Wei Feng thought that as long as this so-called wise old man was well-intentioned, he would not pose any threat to himself. After all, his main task is to bring back the super technology left behind by the Martian civilization, rather than to investigate the origin and origin of the wise old man.

But in this way, another serious problem is placed in front of Wei Feng. That's ...... The fuel left on the Star Ocean spacecraft is only enough for a deceleration and a period of survival. After Wei Feng arrived at the South Gate II Galaxy and slowed down, there was no fuel left to leave the South Gate II Galaxy and return to the Solar System.

Weifeng also does not have a radio communication instrument with sufficient power to send messages directly to Earth from the South Gate Two Galaxy. So...... Even if Weifeng eventually succeeds in obtaining key scientific data, how will Weifeng bring them back to Earth? What's the use of getting those things if you can't bring them back to Earth?

This question made Wei Feng fall into deep worry.

The means of transmitting information by means of gamma ray flashes is not applicable in this case. Because it can only convey some extremely simple information, and the key scientific data that the Martian civilization may have left behind must be extremely large, how can it be possible to transmit so much data back in this way? Besides, at this moment, the solar system has fallen into war, even if Wei Feng has the ability to take this method, how can anyone on the earth side specifically look at the south gate to receive information?

It seems to be another dead knot, a dead knot that cannot be broken.

Wei Feng fell into a long thought. Wei Feng knows that his life or death is actually irrelevant, and the most important thing is that he must send these scientific data back to Earth. Because without these things, human civilization would be in the midst of extinction. These scientific data are the only elixir to save human civilization.

The control room had been silent, and after the message left by Führer Keller had been played, no one in the control room had spoken again. Although it was time to hibernate at this moment, perhaps because he saw that Wei Feng had been thinking, Ye Luo did not say anything to remind Wei Feng.

Wei Feng has been silent like this for several hours. A few hours later, Wei Feng's frowning brow suddenly relaxed. Wei Feng got up from his seat, and then stretched lazily: "Ye Luo, before hibernation, can I drink a little water?" ”

Ye Luo replied: "It's not okay to eat before hibernation, but it's okay to drink water, as long as you don't drink too much, it's okay." ”

"Okay, bring me a glass of water." Wei Feng said.

The cartridge robot sent a glass of water to Wei Feng, Wei Feng picked up the water cup, took a sip gently, and then said, "Ye Luo, I have a way." ”

Ye Luo immediately said: "Is it about the method of sending the scientific data that may exist back to Earth?" ”

Wei Feng nodded: "Yes, I have figured out a way to send this data back." ”

Ye Luo immediately said again, "This is impossible, unless you can think of a way to get enough fusion fuel from the South Gate Two Galaxy. And based on the data we have so far, this is basically impossible. There are no gas planets in the South Gate system, and even if there are gas planets, we don't have the tools to collect fusion fuel. ”

Wei Feng smiled faintly and shook his head: "No, we don't need to get any help from the outside world. The option I came up with didn't require any additional supplies. ”

"It can't be." This is the third time that Ye Luo has uttered the word impossible, "We have little fuel left, and it is impossible for this fuel to support us to return to the solar system." ”

"But the truth is, I really thought of a solution, and I'm 100 percent sure that it will work." Wei Feng said with a smile, then picked up the water cup and drank it down, then turned around and walked towards the hibernation room: "Yes, the way to return to the solar system without obtaining supplies from the outside world...... I've got it...... Ye Luo, you don't need to wonder what my solution is now. When the time comes, I'll tell you about it. Right now...... I'm going to hibernate myself. ”

Ye Luo was silent for a moment, and did not continue to ask Wei Feng what this method was, but said, "Okay captain, the hibernation equipment has been prepared for you. ”

Wei Feng lay quietly in the hibernation pod, and then closed his eyes again. (To be continued......)
