"It is strongly recommended that you do not increase the speed of the Silver Star to the speed of light unless necessary."

"We found out by proofreading the time that there was a two-hour time error between us."

"It means that you've only been traveling at the speed of light for about ten seconds, and in fact two hours have passed in cosmic time."

For the huge volume of the star, the penetration of the silver star is not much different from the medical X-ray taken by human beings, as long as it is not frequently operated, it will not have much impact on the structure of the star itself.

It's just that after slowing down, Lu Yu regained contact with Blue Star while experimenting with precise jumps in this star system, and found that it seemed that the impact on Lu Yu was greater in the state of light speed movement.

According to the special theory of relativity, the closer an object is to the speed of light, the slower its time passes.

Lu Yu's original mouth hi set that the Silver Star was only communicating across space, not over space. If the Silver Star is moving at the speed of light, it means that Lu Yu will lose communication with the Blue Star.

In the past, when facing a supernova explosion, the distance of the Silver Star would definitely be affected by strong gravity, and the speed of time should also be changed.

Considering the armor characteristics of the Silver Star, gravity could not affect Lu Yu in the cockpit. But it itself is completely different when it accelerates to the speed of light, and it seems that this cosmic physical rule has re-applied to Lu Yu.

At this glance, it seems that 3000 points have been spent on the lightspeed engine in vain.

But in fact, there is no use and there is no use, there are two different things.

Lu Yu calculated slightly, and confirmed to Professor Mao with some surprise: "Doesn't that mean that if I had accidentally traveled at the speed of light for more than ten hours before, more than 40 years of cosmic time might have passed?" ”

Professor Mao smiled bitterly and nodded: "It may be longer." So try not to use the speed of light as a means of movement, which will make us lose contact with each other. ”

Lu Yu continued to ask thoughtfully: "How did the stellar-level civilization that has mastered the speed of light travel overcome this time difference to maintain the operation of society?" ”

Time is the most difficult chasm to overcome, and after achieving the speed of light, it is possible to use this method to witness the end of the universe.

And normal social activities, traveling at the speed of light, you only feel a few days on the spaceship, and the normal cosmic time may have passed for a hundred years.

With the current structure of human society, it is impossible to cope with this kind of change.

"It should evolve into a state similar to anarcho-X-ism, where civilizations will no longer have large organizations, but will form small groups with thoughts or goals as the core of action, and spread out to the universe with the mother planet as the connection point."

This is the speculation of the experts of the Blue Star on the stellar civilization, as for the real situation, it is determined that it depends on the observation sample, and in the future, with Lu Yu's footsteps all over the universe, there may be an additional discipline of cosmic sociology on the Blue Star.

At this point, the topic of traveling at the speed of light was almost over, and Professor Mao's expression became solemn.

"Next, let's talk about setting up the system."

"According to the first system settings, you need to increase the technology level of the host's group to get points."

"But on the latest S-level mission, after you almost got the Crystal Cube, the Blue Star Human got 80,000 points for the settlement task without any improvement, which seems to break the previous system setting."

"The first speculation is nothing more than the law of settlement that we have not yet figured out."

"And the second speculation is a bit scary........."

Professor Mao seemed to be very resistant to this speculation, hesitated for a long time and said, "The second speculation is ...... The system determines that you no longer belong to the same race as the Blue Star Humans. After obtaining the Crystal Cube, you will most likely become the only cosmic human, and you only need to improve your level of technology to earn points. ”

After Professor Mao finished speaking, his whole face turned pale.

And after Lu Yu heard the second speculation, his surprise flashed in an instant.

He said categorically: "It has nothing to do with me how the system is defined, I am from Blue Star, and I have always been a human being. ”

"That's enough."

Professor Mao seemed to be infected by Lu Yu's firm emotions, and he hurriedly nodded in response: "Yes!" We're all human beings, and that's enough! ”

...................

When communicating with Blue Star, Seven has been watching from afar, and she doesn't seem to want to communicate with the outside world very much when she is just born.

After Lu Yu finished the communication, she walked over in small steps and whispered to Lu Yu about the precise space jump.

The three-dimensional stellar coordinate map established by the probe instrument can reach each point in precise spatial jumps. Combined with the speed of light, the Silver Star will be a sharp weapon.

Lu Yu looked at this result with satisfaction, his era of cosmic survival has come to an end, and the next exploration of the starry sky is no longer in a passive mode.

After completing a series of explorations of the Silver Star's new features, the Silver Star made a precise jump to the asteroid belt, and the Crystal Cube floated out of the cockpit.

It swelled 10,000 times and then got up, and then a corner of the Rubik's Cube opened, and a robot with horned characteristics came out of it and began to transport the material from the asteroid into a space bubble in the Rubik's Cube.

Obviously, there are many black technologies, but they can only use this way to transport matter, which can be regarded as a wonder in the universe.

After carrying trillions of tons of material from the asteroid belt of the star system, the Silver Star jumped away.

Matter is nothing to the Silver Star, if Lu Yu is willing, he can be a miner in this star system with no signs of life for thousands of years.

But he left anyway, and the Silver Star was destined to shuttle among billions of stars.

It's just that there are so many galaxies in the universe that trying to find the Milky Way from them is like looking for a needle in a haystack, and it may take millions of years to sift through them one by one by jumping through space.

So over the next three years, the Silver Star found five planets that had given birth to life, but had not yet given birth to civilization, in frequent space jumps. I saw stellar embryos, I saw black holes devouring stars, but I still didn't find any trace of the Milky Way, and I didn't encounter another civilization.

Three years have left no trace on Lu Yu, and the limit of his lifespan seems to have been stripped from his life attributes.

Lu Yu still has 2,000 points in his hand, which is enough to exchange for black technology that greatly increases his lifespan.

Thinking about it this way, it is actually not unreasonable for the system to separate Lu Yu as a so-called cosmic human being.

On this day, the Silver Star, as usual, began to leap towards the next bar-shaped galaxy.

And this time, they arrived in a special star system.

This is a very different star, about the size of the Sun, but with the mass of 10,000 times the Sun.

In this case, it should have collapsed into a black hole a long time ago!

What's even more bizarre is that under such a terrifying mass, there are actually 24 planets next to this star!

When the Silver Star suddenly appeared in this special star system, one of the gas planets began to form a huge eye shape!
