The route was much longer than one might think, and by the time Liu Fei gave the order, the spacecraft had been on the road for seventy-two hours, and it was flying at full speed.

During the seventy-two hours of the flight, the improvised scientific team was constantly analyzing the engine ejection material and calculating the time of the most recent voyage.

Liu Fei did not pay attention to the research topic of the temporary scientific research team, he was only interested in Xiao Qiangguang Brain, these 72 hours, Liu Fei took a tour of the massive information provided by Xiao Qiangguang Brain, and he found that except for the star map marked with the year 2009 A.D., there is no information related to time.

Could it be that Xiao Qiangguang Brain deliberately leaked this secret?

Vaguely, Liu Fei seemed to feel that something was unusual, with the powerful computing power of the chip matrix of the small strong light brain, it was impossible to miss this important information confidentiality work.

Undoubtedly, Xiao Qiangguang Brain has already predicted Liu Fei's current route, and also expected that Liu Fei will access the star map in the database for comparison, so it is certain that Xiao Qiangguang Brain seems to want to rely on this star map to predict something to Liu Fei......

……

What are the intentions of the little strong light brain?

Why didn't Xiao Qiangguang Brain tell him directly?

"Mr. Liu, have made a new discovery?" Burleigh interrupted Liu Fei's thoughts.

"Huh?" Liu Fei got up when he heard the sound and walked to the side of the main control platform.

"Look here."

Burleigh pointed to the virtual star map on the hologram with a solemn expression, there was a band of light in the middle of the virtual star map, and the band of light extended to the depths of the vast star map.

After seeing Liu Fei coming, Burleigh began to operate the main console, and the virtual star map changed, like an animation, and the eye-catching light band began to move forward dynamically, as if it was simulating the flight of a spaceship.

Just when Liu Fei was about to ask what the light band was, the light band suddenly disappeared into the star map, disappearing very suddenly, as if the road was suddenly cut off when he was driving a vehicle running on a wide road.

"What happened?" Looking at the band of light that stopped abruptly, Liu Fei asked.

"This band of light is a simulated route."

"Route?!" Liu Fei was stunned.

"Yes, this is the once thriving route we found, but it was interrupted in this place, and it was very sudden!"

"What else did you find?" Liu Fei knew very well that Burleigh was a person who was inclined to evidence, and if he didn't find it, he wouldn't report it to him.

"Yes, when we found out that the route suddenly disappeared, we immediately detected it through the optical mode and found that at the end of the route disappeared, there was a huge black hole."

"Black hole, are you sure?"

Liu Fei's heart was shocked, he knew very well the meaning of the word "black hole", black hole, symbolizing death and mystery.

Obviously, the appearance of black holes at the end of a shipping route is not in line with human interstellar navigation habits, whether it is when human beings explored star fields in the early days or now, the interstellar routes opened up by human beings can never have black holes.

A black hole is a celestial body with such a strong gravitational pull that even light cannot escape. When the Schwarzschild radius of a star is so small that even the light emitted from the vertical surface cannot escape. At this point, the star becomes a black hole. When we say "black", we mean that it is like a bottomless pit in the universe, and once any matter falls into it, it "seems" that it can no longer escape. Since the light in a black hole cannot escape, we cannot observe a black hole directly. However, its existence can be observed or inferred indirectly by measuring its effects and effects on surrounding celestial bodies. By extension, a black hole is a condition from which there is no escape.

For human beings, the most terrifying thing about black holes is not their irreversible destruction, but the breaking of the concept of human time.

When people developed the warp engine, human beings have been able to control the jump of the spaceship to a time singularity, which is a very great discovery, because when the engine breaks through the speed of light, time will cause confusion to human thinking, and even time and space disorder, and the determination of the time singularity allows human beings to ensure that every jump of the spaceship will conform to the human concept of time, and there will never be a time rewind, or go to the future.

In the universe, there are many mysterious forces that affect spaceship navigation, and the black hole is one of the countless forces, which not only devour spaceships, but also make the warp engine lose its limitation on the time singularity, resulting in space-time chaos.

There was a terrifying case in the history of human interstellar travel, when a spaceship broke into the space of a black hole due to a meteorite turbulence.

This voyage, which should have been an accident, has affected humanity for hundreds of years, and continues to this day.

This spaceship appeared in another star field a few years later, and when it appeared, a large number of unknown creatures poured out of the spaceship, these creatures are not predatory, but the damage they cause to humans is more terrifying than the aliens who have been fighting with humans for more than a hundred years, because they can open up the four-dimensional space in the three-dimensional space inhabited by humans......

This time the disaster is far beyond the alien, because, the human dream is to the four-dimensional space, human scientists also believe that human beings will eventually evolve to the four-dimensional space, and even multi-dimensional space, when the mysterious four-dimensional space and the three-dimensional space appeared after the passage, tens of thousands of human scientists flocked to the four-dimensional space like moths to the fire, unfortunately, all the aviation tools of human beings were torn into pieces at the mouth of the four-dimensional space, turned into nothingness, three-dimensional space of human beings, In other words, the scientific and technological power of three-dimensional space simply cannot possess the four-dimensional space of the timeline through the channel.

Fortunately, the creatures in the four-dimensional space are obviously unable to adapt to life in the three-dimensional space, so after a short period of time, the unknown creatures in the four-dimensional space disappeared, and the opened four-dimensional space channel was also closed, however, this short time has caused the heaviest blow to mankind in human history, and a large number of top scientists of mankind died in the exploration of the four-dimensional space, which brought a fatal blow to the development of human science and technology.

Since this incident, the development of human space navigation technology has been stagnant, and from beginning to end, human engine technology has stayed on the warp engine.

It is worth mentioning here that, in fact, the warp engine is not the full name of the space jump engine, but the full name is the singularity limit warp engine.

At the beginning, when mankind developed the singularity warp engine, scientists asserted that mankind had taken a crucial step towards the four-dimensional space, but unfortunately, after that disaster, the scientists who studied the singularity limit warp engine were martyred, and the pace of mankind to the four-dimensional space also stagnated.

Could this be the place where those scientists were martyred?

Liu Fei and Burleigh subconsciously glanced at each other and had the same idea, but the difference between the two was that Liu Fei was still calm, while Burleigh's eyes were full of fanaticism.

Burleigh was not a scientist, but his yearning for the four-dimensional space was no less attractive to him than the fanatical scientists who died hundreds of years ago.

Because there were so many scientists who were martyred that time, it has affected the future of mankind, so the Human Alliance has set the place where the four-dimensional space was discovered as a top secret, and even after hundreds of years, these secrets have not been declassified.

In fact, for hundreds of years, scientists in the seven star fields have been calling on the government to declassify the relevant materials of the four-dimensional space, but there is not much progress, and some scientists suspect that the government may have completely destroyed the relevant materials of the four-dimensional space hundreds of years ago.

Liu Fei didn't have the spirit of Burleigh's martyrdom, he was just thinking, why did Xiao Qiangguang let him discover this place?

"Mr. Liu, shall we pass?"

Burleigh's eyes turned red, and a pair of eyes were fixed on the strip of light on the holographic screen, where the passage to the mysterious world was located......
