At this time, Lu Xingchen's speed was already several nines above the speed of light, and his time had also expanded to the limit.

Looking at the mysterious celestial body frozen in a fixed position, Lu Xingchen finally accepted the reality.

"This is incredible! Even if this mysterious celestial body is also moving at a speed approaching the speed of light, it can't possibly reach this level!"

Lu Xingchen stopped and turned around to head back.

On the way, Lu Xingchen finally thought of something that was terrifying when he thought about it carefully.

He still remembers his childhood, that is, before he traveled through time.

At that time, Lu Xingchen lived in a small mountain village in a valley.

I still remember that at that time, there was no light pollution in the mountain village, and the starry sky was in full view.

As a child, Lu Xingchen could open his eyes to look at the sun and see everything clearly. He could even easily see the faint Milky Way!

At that time, Lu Xingchen was strolling along the mountain path, asking his cousin who had returned home for the holiday with childlike innocence.

"Cousin, why do the moon and stars always follow us when we walk?"

The cousin touched Lu Xingchen's head lovingly and explained the principle to Lu Xingchen in the simplest and most understandable way.

"Wow, is it just because they're so far away? Are all stars like this?"

The cousin gave an affirmative answer, and Lu Xingchen nodded as if he understood, but his attention was always attracted by a shining celestial body.

Lu Xingchen didn't specify the direction, but casually asked what the brightest star in the night sky was called.

The cousin hesitated for a moment and told Lu Xingchen that it was the North Star.

Lu Xingchen was a little puzzled, because the shining celestial body he saw was clearly in the west...

From then on, this shining celestial body naturally implanted a trigger for Lu Xingchen.

Later, Lu Xingchen grew up slowly and studied hard, hoping that one day he could go into space to see this celestial body.

But fate is cruel. No matter how hard Lu Xingchen tries, going into space has become an unattainable dream.

Later, Lu Xingchen unexpectedly traveled through time and space, and gradually mastered extremely powerful black technology, even becoming the current master of the galaxy.

But this mysterious celestial body is still out of reach for Lu Xingchen.

"Back when I was on Blue Planet, the moon followed me wherever I went because of the distance."

"Distance is no longer a problem for me now, but this celestial body is still out of reach. Could it be because it has exceeded the scope of distance?"

Lu Xingchen thought carefully. If his reasoning was correct, then the cause of this might be the dimension!

"This shouldn't be possible, right? But there's no other reasonable explanation right now..."

Before he knew it, Lu Xingchen had arrived at a strange location.

At this time, next to Lu Xingchen was a rocky planet - Gliese 581g.

Lu Xingchen just wanted to find a quiet environment to think, so he moved towards the planet.

While moving, Lu Xingchen checked the position of the planet.

"It's not bad. It's quite close, only about twenty light years away from Blue Star. I'll take a short break before returning to Blue Star. This will give them some time to develop."

Thinking of this, Lu Xingchen sped up and arrived at the boundary between day and night at Gliese 581g in the next second...

"My goodness, this planet is tidally locked! This isn't a very suitable environment for the birth of life!"

After Lu Xingchen finished speaking, he passed through the atmosphere and landed on the surface of Gliese 581g.

Lu Xingchen's destination at this time was somewhat beyond his expectations.

Because there are sparse plants at the boundary between day and night!

These plants have strange shapes, a bit like the deformed cactus columns on the blue planet.

Lu Xingchen walked around and didn't find any animals, so he decided to create a space for himself.

"Good! Now I'm going to build a quiet shelter a hundred meters underground!"

Lu Xingchen's words came true, and soon abnormal gravitational fluctuations appeared in the sky above Gliese 581g.

A strange force gathered and began to decompose and reorganize the elements to build a shelter for Lu Xingchen.

The force was very fast. Lu Xingchen smiled slightly and stepped directly into the elevator in front of him.

The next moment, Lu Xingchen arrived at the shelter.

"Not bad, not bad, it's actually built according to my favorite aesthetic!"

After settling everything, Lu Xingchen sent a short message to Aqiang.

"Aqiang, due to some special reasons, I will be back to Blue Star in a year. You guys should keep up the good work during this time! I'm busy right now and can't reply to messages. If anything happens, just leave a message."

After sending the message, Lu Xingchen put down all his burdens, turned off all communication devices and began to meditate quietly.

"An extra dimension? Or is that mysterious object a product of four-dimensional space, and what I see is just its projection in three-dimensional space?"

"Fourth dimension has an additional dimension of time compared to three. In four-dimensional space, time is not irreversible like in three-dimensional space. Instead, it becomes a mountain peak. I can go up or down, I can go back to the past, or travel into the future..."

Lu Xingchen thought and looked for logical flaws.

"But if that's really the case, then what's the point of a four-dimensional civilization doing anything?"

"If you could travel back and forth between the past and the future, wouldn't everything be changeable to the point of losing its meaning?"

The more Lu Xingchen thought about it, the more he felt something was wrong, and soon he smiled helplessly.
