In the vast universe, apart from celestial bodies such as stars, planets and comets, it is not an absolute vacuum.
There are large amounts of interstellar dust floating in many places.
Their compositions are not essentially different from those that make up planets.
They are all particles of rock and metal.
Under the constraints of appropriate gravity and spiritual magnetic fields, they condense into cloud-like celestial bodies, so they are also called "nebulae". ".
The relics of the Pangu civilization "Kunlun" are hidden in a Crab Nebula, and now there is another "Black Spot Nebula".
Perhaps the Pangu civilization mastered some secret method that can control the nebula, which is unknown.
Li Yao knew that depending on the composition of the metal particles in the nebula and the changes in the spiritual magnetic force field that condensed them, the nebula could show various incredible characteristics, such as sending and shielding special radiation, absorbing and releasing spiritual energy, and so on. .
"That's all we know right now."
Professor Mo Xuan said, "Although we found the other party's location, it was shrouded by a large 'Black Spot Nebula'.
With our current technical level, it is impossible to directly observe the other party in the three realms of Tianyuan, Feixing and Blood Demon, and spy on its location."
False and true!”
"However, from the scale of the universe, the distance between the other party and us is not very far.
Such a mysterious and unknown world suddenly appeared from around us and took the initiative to say hello to us.
I really can't tell whether it is a blessing or a curse. ” "How can we allow others to snore and sleep on the side of the bed, especially such a person whom we know nothing about!"
"The most important thing is, come on, come and take a look.
This is the simulated trajectory map we formed by merging the Panguwen star map and the "Heavenly Tribulation Observation Map" in Cixingzhai.
Have you found the problem?"
Professor Mo Xuan pointed at the top of the screen and said, "Yes, this mysterious world is not very far from the route of the Imperial Expeditionary Force of the Real Humanity.
A hundred years later, when the Imperial Expeditionary Force passes by them, it is certain that this world will be discovered.
Just like Su Changfa and other immortal cultivators who discovered Kunlun five years ago."
Li Yao breathed a sigh of relief.
Just think about letting Su Changfa and other immortal cultivators monopolize Kunlun, and you can imagine the seriousness of this matter.
"Kunlun" is just an "arsenal" built by Pangu civilization using the spiritual energy emitted by pulsars.
Since this mysterious world is regarded as an escape destination by countless Pangu people, it is obviously an important stronghold for them.
Regional military centers and the like.
If such a world is inextricably linked to the Imperial Expeditionary Force, it will definitely not be a good thing for the Federation, which is preparing to prepare.
After all, after hundreds of thousands of years of vicissitudes, does this extremely mysterious world still exist?
And what race and civilization are they living in this world now?
This area is far away from the prosperous area in the center of the Star Sea, so it is unlikely to be people from the Empire and the Holy Alliance.
Who is it?
Is it a demon clan or a demon cultivator, or even a descendant of the Pangu clan or the Nuwa clan?
Or is it something even more bizarre?
Also, why do they "greet" the two worlds of Tianyuan and Feixing?
Are they in good faith or malicious, do they really want to communicate, or are they harboring evil intentions and setting a trap?
"I see!"
Li Yao narrowed his eyes and said, "Now that we have discovered the other party, we must not sit idly by and ignore it.
We can only use the stupidest method to send an expedition team as soon as possible to jump into this mysterious world to spy on the local reality and figure out the other party. position, level of civilization, whether it poses a threat to us, whether it will be used or even conquered by the Imperial Expeditionary Force, and so on!"
"Otherwise, if we have been working hard for a hundred years and thought we were invulnerable and sure of victory, but in the end, in addition to the Imperial Expeditionary Force, there was also a powerful enemy from another mysterious world who came to kill us, that would be funny!"
"What the teacher calls 'special tasks' is this, right?
What else is there?
I'll go and do it.
This is the right professional counterpart!"
Professor Mo Xuan and Sikoolie looked at each other.
The professor coughed dryly and said, "Li Yao, don't be impatient.

Just listen to what I have to say."
"This mysterious world hidden deep in the Black Spot Nebula is very different from the other star fields that the 'Pilgrim Project' will explore."
"First of all, it is extremely far away.
As you can see, it is almost at the edge of the Pangu Star Map.
It is extremely difficult to jump directly over!"
"Secondly, there are dozens of star systems near this mysterious world, all shrouded in fog.
We have no idea what's going on inside!"
"Trying to search for a world that was hidden hundreds of thousands of years ago in such a dark nebula that blocks the sky is tantamount to finding a needle in a haystack.
It is dozens of times or even more difficult than searching for other worlds. hundred times!"
"Therefore, the starship that carries out this expedition must be able to withstand hundreds or even thousands of star sea jumps, must have a very strong conventional sailing speed, and preferably have the ability to receive signals released by the Pangu civilization, and Fully equipped hibernation system.”
"Looking at the Three Realms, our starship refining level is not enough to directly refine such an expedition ship.
Including the multi-functional expedition ship 'Spark' from the Star Sea Empire era, we do not have this capability."
"Only this 'Mars', which was transformed from the Pangu Civilization's single-person escape capsule and is one level smaller than the Spark, has this ability!"
"Fellow Daoist Sikou also said just now that the 'Mars' was transformed from the Pangu Civilization's single-person escape cabin, and directly used a large number of Pangu Civilization's magic units.
This means that it is unique.
We have developed it in a few decades.
It’s impossible to refine a second one!”
Li Yao finally understood and took a breath and said: "The teacher is saying that with our current technical level, we can only launch the 'Mars' and carry an explorer into the dark nebula to find the strange things that happened long ago.
The mysterious world that disappeared?"
"Yes."
Professor Mo Xuan nodded and said, "This is purely a hammer deal.
If this explorer is trapped deep in the Dark Nebula, we don't even have the ability to organize a rescue team.
We can only give up this mission completely and wait for one day.
Came to your door!
” "And this is not the most special part of this mission."
"Well?"
Li Yao was dumbfounded, "It's all so exaggerated.
It's not the most special thing.
What's the problem?"
"The problem is that the speed of Mars is too fast.
Not only is it first in the three worlds, but it is also several times ahead of the second place, reaching true sub-light speed!"
Si Kolie took over the words and said: "It can accelerate to the 'sub-light speed' state immediately after completing the star sea jump.
This is the biggest reason why we chose it to explore the dark nebula."
"Isn't that great?"
Li Yao didn't understand, "Since the 'Mars' can repeatedly jump across the star sea many times, has the ability to sail at sub-light speed, and is itself a modified escape capsule of the Pangu tribe, it has a high probability of receiving the other party's signal.
It's simply It’s tailor-made for this exploration mission, and it’s fast, so what’s wrong with it?”
“Have you ever heard of the ‘clock slows down’ effect?”
Skoulie smiled bitterly and said, "To put it simply, when an object gradually approaches the speed of light, the time around it will rapidly slow down and the space will shrink rapidly.
The closer it is to the speed of light, the thinner the meaning of time and space.
Once it reaches the speed of light, , time will stop, space will collapse into a point, and enter the state of 'zero space-time'!"
"Reaching or even exceeding the speed of light is something that is completely unimaginable at our technological level, so the 'zero space-time' state is just our guess."
"But when approaching the speed of light, time slows down relatively, which is an observable and confirmed fact."
"In our past interstellar voyages, most of the time we relied on star sea jumps to bypass the 'speed of light' barrier.
During regular voyages, our starships could rarely maintain sub-light speeds, and they could only rush up for a few seconds at most.
It’s just a clock!”

"So, even if the phenomenon of 'clock slowing down' really exists, its impact on us would be minimal and can be ignored."
"This mission is different."
"First of all, the 'Mars' that carried out this mission is the fastest starship in the three worlds.
It can easily break through the sub-light speed and maintain it for a long time.
Secondly, it is destined to fly at the sub-light speed for a long time before it can find the hidden space.
A mysterious world deep in the dark nebula!"
"These two factors taken together mean that for the explorer driving the Mars, his perception of the passage of time is different from that of the people who stayed in the three realms of Tianyuan, Feixing and Blood Demon!"
"Perhaps in his opinion, it was only a year and a half of exploration, while in the Three Realms, decades passed in a hurry."
"Do you understand, Li Yao?"
Professor Mo Xuan sighed and said, "If we really want to explore this mysterious world, we can only send out one explorer.
Even if it is smooth sailing for him, he completes the exploration, mapping and positioning, and returns to By the time we reach Tianyuan Realm, it is very likely that decades or even hundreds of years will have passed!"
"This is the most special and complicated exploration mission in the Pilgrim Project."
"In other worlds, the waterways are relatively clear and the positions are relatively clear.
There is not much interference.
It is best to find it.
If you can't find it, you will immediately jump to a new star field to find the next one.
There is really no gain.
Three or five You can return to the Federation within 20 years, or at most ten years, to reunite with your family and advance other projects.”
"Only for this task, the uncertainty is too great, and the time is too long!"
Li Yao and Ding Lingdang were silent at the same time.
The clock slowing effect?
The closer we get to the speed of light, the slower the passage of relative time?
It would take at least several decades to carry out such an exploratory mission?
This was something the two of them never thought of before coming together.
"No matter how difficult the task is, how long it takes, or how costly it is, we have to carry it out, right?"
Li Yao spoke seriously and said seriously, "Because there is no way we can just watch a mysterious world emerge from around us and greet us carelessly, but ignore it or have no reaction at all, right?"
