章 259: Chapter 259: Life in Stellar Cavities and the Bomb
After the spaceship arrived within the star system, the Kunlun, which Yan Xia was on, was about to leave.
However, before they could even exit the star system's radius, a message was sent back from within the system.
The star system lacked heavy elements, and through mass calculations, the battleship's main system discovered a cavity inside the star.
This news instantly pulled Yan Xia's genes back over forty thousand years to the cavity of the South Gate, the cavity of SC-8 on the Cosmic Silk Road. This was the third time Yan Xia had heard about stellar cavities.
As they had not been discovered before, Yan Xia had almost forgotten about the existence of stellar cavities. Now that they were discovered again, it proved that the civilization did not create these stellar cavities solely for energy collection.
"If it was for energy, there's no need to place them at such a distance, and they wouldn't need to specifically look for dwarf stars."
"Ella, analyze their distance relationship."
The three stellar cavities didn't seem to have any particular pattern in their positions, but Ella had a guess.
She simulated the entire Milky Way and then studied their orbits, reversing time.
In the end, she determined that these three stars were in a straight line tens of thousands of years ago. Through this calculation, Ella drew a diagonal line on the simulated Milky Way, connecting some stars, and asked Yan Xia, "I want to send a spaceship to this star to see if there's a cavity inside."
This was a blue dwarf star, and Ella excluded the red dwarfs on the line.
"No problem."
Yan Xia also wanted to take a look.
If this was the case, then tens of thousands of years ago, a Gate-level civilization had left these cavities in the sky, and these cavities might have been created casually by them.
Is that so?
At least at this stage, Yan Xia thought so, because he couldn't see any other purpose for these devices; they were just simple energy storage devices.
"Let's stop and send a spaceship to take a look."
Yan Xia relaunched the spaceship. The current spaceship within the star system didn't have the capability to enter the interior of the star. After all, they were biological battleships, and the drawbacks of biological organisms became apparent; they couldn't withstand extremely high temperatures.
Biological battleships could withstand temperatures below 2000 degrees Celsius, but not above. Above 2000 degrees, the biological battleships would turn into meat patties. This was the limit of the Federation's biology; it was almost impossible to make life forms withstand temperatures of tens of thousands of degrees.
As an expert in biology, Yan Xia knew that the Federation's biology could create some high-temperature-resistant white rats, and every 1-degree increase in temperature was a significant advancement.
Unlike regular material science, progress in biological materials science could be described as painstakingly slow.
The new spaceship arrived at the star's surface a few years later and crashed into it. Soon, the cavity's location was confirmed.
After waiting for a few months, Yan Xia received new information from the spaceship, which had already left the star and sent back some photos and videos. Yan Xia was astonished when he saw the photos.
This stellar cavity was different because there was a star city inside.
Yan Xia had just named this star FS-17, with a diameter of 1.48 million kilometers. The diameter of the cavity inside was 2973 kilometers, and within the entire cavity was a star city with a diameter of 178 kilometers. There were mountains, water, and even living organisms, making it seem like a small world.
These organisms were all low-level, and they were definitely not latecomers but were placed inside along with the creation of the cavity.
"Could it be that the civilization was trying to make life reside inside the star?"
Yan Xia didn't know if there was any purpose to this; the cost far outweighed the benefits. However, that civilization was indeed doing it.
The sky dome of the star city actually had some anti-light and anti-particle functions, allowing the star city to maintain a livable ecological temperature even within the star.
The environment inside resembled a rainforest, but it was filled with a type of mushroom tree. These mushroom trees had branches like fungi, and their leaves were like regular tree leaves but thicker and slightly translucent, like jelly.
These mushroom trees grew densely, intertwining and competing for the sunlight from above.
The organisms were somewhat bizarre. Some were similar to tadpoles but moved on land like snakes, with short antennae on their foreheads. At the ends of these antennae were eyes, which looked like they could drive someone insane.
There were other types of organisms, but they were similar, resembling amphibians.
"It might not be a biological experiment site."
"After all, it doesn't seem like a place where intelligent life has lived."
Yan Xia planned to send the spaceship inside to study the interior in detail, and for this, he could wait for decades. Something left behind by a civilization in so many stars shouldn't be so simple.
To create such cavities in these stars would require the consumption of a significant amount of resources for the current Federation. If it were meaningless, that would be truly unacceptable.
...
Decades of research passed in the blink of an eye.
As expected, Ella discovered something.
Previously, it was thought that the stellar cavities were energy storage devices, but after decades of repeated observations, Ella finally confirmed that these were not energy storage devices but bombs.
In fact, it would be more reasonable to consider them bombs, as energy storage devices wouldn't have much energy if they were just heavy elements.
Moreover, heavy elements generate energy through nuclear fission, which is far less efficient than the nuclear fusion of light elements. Higher civilizations don't need these heavy elements as an energy source.
There's no need for that, either, because how many heavy elements can a yellow dwarf star have? It would be more convenient to go directly to the Orion Nebula or some dying supergiants to find them.
But...
If they were bombs, what was the civilization that created them trying to blow up?
The explosion of these heavy elements within the star would undoubtedly destroy the star. What benefit would this destruction of the star bring to that civilization?
Unknown!
However, it can be confirmed that this civilization is currently one of the top civilizations in the Milky Way.
They might be in a game.
Yan Xia had previously destroyed a node, and he didn't know if the civilization would hold a grudge against him.
"Let's stay away from these cavity stars for now."
Yan Xia decided not to set up a transit station here or continue investigating the life forms within the cavity. The issue with the Olive Branch civilization hadn't been resolved yet, and they couldn't afford to provoke another powerful civilization.
The fleet started again and completely withdrew from the star system. During this 8000-year journey, the situation with the Olive Branch civilization seemed to have reached a stalemate, and neither the planet nor the Star City nor the Federation had made any moves. This had been going on for several years, leaving people perplexed.
In the universe, various civilizations blossomed, and their diverse methods made them hard to predict.
Indeed, this was a vast forest where one had to tread carefully.
After reaching Sirius, Yan Xia's grand plan also began to be implemented...
