A great man once said: In the human body, there is a very adventurous spirit of blood.

It is also the spirit of adventure that has allowed human beings to evolve from undersea creatures to human beings, and in this long evolutionary process, the spirit of adventure and exploration has almost become the mainstream of human evolution, including the discovery of optoelectronics, the invention of TNT explosives, and the development of nuclear weapons, which are the fruits of adventure and exploration for human beings, and it is these seemingly extremely accidental adventure results that have promoted the progress of human society and the vigorous development of science and technology.

Even in the space age, the increasingly powerful human beings are still full of infinite yearning for the unknown world, which shows that exploration and adventure have been integrated into the human soul and become an indispensable spirit.

Human exploration of the three-dimensional space has existed hundreds of years ago, the only difference is that at that time, human beings could not find the passage outside the three-dimensional space, and could only theoretically reason about the space outside the three-dimensional space, such as the four-dimensional space, the five-dimensional space, and even the multi-dimensional space

There is a very complete system for theoretical knowledge outside of three-dimensional space in the human world, but how to break through the shackles of three-dimensional space has always been a difficult problem for human scientific research.

As early as when mankind developed the warp engine, human beings were full of confidence in breaking through the three-dimensional space, but the warp engine did not bring exciting news to scientists, but was a disaster one after another: all the warp engine spaceships disappeared forever in the universe outside the three-dimensional space, and they did not know whether they were alive or dead.

Human scientists have summed up a variety of possibilities, among which there are three most prevalent possibilities, first, even if the human aircraft reaches the speed of light, but the scientific and technological power is still unable to break through the three-dimensional space, and all the spaceships that have been explored have been killed.

Secondly, those who have entered the four-dimensional space or the multi-dimensional space no longer want to return to the three-dimensional space, and even forget their mission.

The last possibility is that outside of the three-dimensional dimension, there are powerful races, and those races are extremely aggressive, and they are hostile to life outside of their own space.

In order to avoid catastrophic consequences, human scientists have developed the Singularity-Limiting Warp Engine, which allows even warp engines that reach the speed of light to appear only at time nodes in three-dimensional space, without causing space-time turbulence.

In fact, the singularity limits the emergence of warp engines, maintaining human and spatial stability.

……

There are all kinds of possibilities, and the last one is very probable, but it is the least convincing, because, according to the theory of biological evolution, the more intelligent the creatures, the more inclusive and civilized they will be, and those creatures that emerge from the four-dimensional space have proved this, although they are powerful enough to open the passage between the three-dimensional space and the four-dimensional space, they are very friendly, and there is no scene of killing people for fun and destroying the balance of space.

Regardless of what kind of possibility, it can be said that every human being is full of indescribable curiosity about the space outside the three-dimensional space, and it is precisely because of this curiosity that human scientists in the entire universe are rushing to join the exploration of the four-dimensional space in person, even if the interstellar federal government strictly prohibits scientists from exploring the four-dimensional space, those scientists will not be able to sneak the spacecraft to the sacred place of their dreams. Of course, in the end, there was no result, and this kind of martyrdom-like exploration was not curbed until the government blocked all information related to the four-dimensional space, and the suicidal exploration of human scientists like moths to the flames......

Burleigh is not a scientist, but he still has the adventurous spirit of scientists, but unfortunately, Liu Fei is not.

Liu Fei cherishes his life quite much, and if he is not absolutely sure, Liu Fei will definitely not take risks, unless, in the absence of a choice.

The spacecraft has been hovering around the black hole for a whole week, and if it goes a little further, it will be in the realm of the black hole's terrifying suction.

Around the black hole is a barren, cold, dark void with almost no matter, and even cosmic dust is negligible.

Clearly, the black hole devours the surrounding matter.

In this week, Liu Fei was not idle, he consulted a large amount of information, and he personally participated in the definition of the age of the engine eruption.

Liu Fei came to a conclusion: this route is not the route where scientists were martyred!

The reason is very simple, because there is a small time difference between the time when this route appeared and the time when scientists were martyred, in order to determine this time difference, Liu Fei repeatedly argued many times to determine that this time difference exists.

After coming to the conclusion of the time difference, this route seems more and more mysterious, after all, in the historical records of the migration of the human universe, there is no such route at all, which is really unimaginable, you know, this route has passed through a total of thousands of spaceships.

The fact that a route that once had thousands of general types of spacecraft was forgotten is incredibly alluring......

……

Boehly and they were all anxiously waiting, waiting for Liu Fei's decision.

In fact, there are only two options now, first, to deviate from course, or to go back the way you came, because in front of you is a huge black hole capable of devouring stars; Second, they are convinced that the black hole was formed earlier than the time of the course formation, which means that the black hole already existed when thousands of general spacecraft passed here, which can only show that the black hole is likely to be an unknown safe passage.

Whether it is the four-dimensional space passage where scientists were martyred or the unknown safe passage, this has an extremely strong temptation for Burleigh.

Of course, the main reason for Burleigh's adventure is the current environment, now the new Kodo Space City is equivalent to an island, and the New Kodo Space City itself does not have the ability to develop a warp engine, if they do not take the risk, it will mean that they will spend years, decades, or even a lifetime in this vast and ethereal universe to find traces of human beings.

No one wants to stay in the cold universe for the rest of their lives on that endless and boring voyage, and neither does Burleigh and his men, they just want to be the first to connect with the human world.

In fact, Liu Fei is also aware of this.

"Ready to pass."

After hovering in front of the black hole for eight days, Liu Fei finally made a decision, and his trust in Xiao Qiangguang's brain finally prevailed over reason.

Since Xiao Qiangguang Brain deliberately left clues to discover this route, then, this route should be safe.

Up to now, Liu Fei still trusts Xiao Qiangguang Brain very much, even Xiao Qiangguang Brain often inadvertently reveals his treacherous and obscene side.

"Main Engine Acceleration!"

Burleigh shouted excitedly, and immediately, the spaceship began to accelerate, charging towards the black hole in a gesture without hesitation, people's eyes were fixed on the holographic screen, and a feeling of blood boiling inexplicably rose......
