Moreover, the Demon God Civilization has unified this star cluster, and the civilizations in this star cluster all respect the Demon God Civilization. The Demon God Civilization has no reason to destroy these civilizations ruled by it. This will only bring harm to the Demon God Civilization.
No benefit.
Lin Yun couldn't help but think of the "truth" spoken by the Ancient Heavenly Lord.
Is all this related to the "truth" mentioned by the Ancient Heavenly Lord?
Putting these thoughts aside for the time being, Lin Yun continued to explore the star cluster.
Soon, Lin Yun discovered a huge ring-shaped structure a few light years away.
This ring-shaped structure is like a huge ring, enclosing a star in the middle, making it look out of place among the stars.
"Is this the "stellar energy ring" they mentioned?"
Lin Yun had seen records about "stellar energy rings" in the information of previous civilizations.
"Stellar Energy Ring" is an artificial celestial body used to collect stellar energy. It can absorb most of the energy of stars and solve energy needs for the development of civilization.
The "stellar energy ring" is an important symbol for a civilization to enter a saint-level civilization.
According to the civilization level planning of the Demon God Star Cluster, civilization can be divided into four levels according to the degree of energy development of its civilization, namely: god-level civilization, saint-level civilization, heaven-level civilization, and human-level civilization.
Human-level civilization: The civilization has limited energy mining on the planet and can only mine some ores. The technology is backward and civilized individuals cannot leave the planet.
Heaven-level civilization: A civilization that can exploit all the energy of the planet and has relatively advanced technology. Individuals can leave the planet through cultivation or rely on technological shipping methods.
Saint-level civilization: The civilization can use the "stellar energy ring" to mine all the energy of the star. The technology is very advanced. Individuals can navigate the interstellar space and even survive for a long time in the interstellar space. They have the ability to colonize other civilizations.
God-level civilization: A civilization that can exploit all the energy in the galaxy, is highly technologically advanced, and can do anything individually.
According to this standard.
Tianwu Continent belongs to the lowest human-level civilization.
And today's divine and demonic realms have only barely reached heaven-level civilization.
As for the Demon Realm and the Divine Realm 100,000 years ago, they were between the heaven-level civilization and the holy-level civilization. The strongest combat power in their civilization had reached the standards of the holy-level civilization. However, the technology lagged far behind that of the holy-level civilization.
Civilization is still at the stage of heaven-level civilization.
The Saiyan civilization has completely reached the holy level. There are also many powerful true gods in its civilization.
There is only one god-level civilization, and that is the supreme demon civilization!
Although Lin Yun was well-informed, this was his first time seeing a stellar energy ring, so he couldn't help but take a few more glances.
The diameter of this stellar energy ring reaches an astonishing 100 million miles, completely wrapping a sun and being surrounded by endless void energy.
The stellar energy ring presents a perfect spherical shape, a deep and magnificent scene.
The whole thing is constructed of black special material, making the entire stellar energy ring emit soft light, like a sun shining with dazzling light.
Lin Yun probed into it with his spiritual consciousness and was even more amazed.
Because inside the stellar energy ring, there is actually a vast and boundless ecological environment.
A huge forest!
The vast grassland!
Lakes and rivers crisscross each other, forming a perfect natural landscape. To this day, dense vegetation continues to grow.
It is no less magnificent than the magnificent buildings of previous civilizations, and is spread throughout the interior of the star's energy.
There are all kinds of high-rise buildings, and there are even sets of energy conversion machines that are so complicated that even Lin Yun can't distinguish them.
Even after so many years, there is still a constant supply within the entire stellar energy ring.
This is a completely self-sufficient ecological environment!
The spiritual energy content in it is far superior to that of the Three Realms. It is not an exaggeration to call it the "Immortal Cave".
If ordinary people could live in it for a period of time, with extremely powerful technology and strong fairy energy, their growth would be unimaginable.
However!
Just like before, Lin Yun never sensed any life breath even inside this stellar energy ring.
"The more powerful these civilizations are, the weirder things become..." Lin Yun sighed in his heart.
At least from the current point of view, the 18,000 civilizations in the "Devil Star Cluster" are all extremely powerful.
But even these powerful civilizations mysteriously disappeared 300 million years ago, and all living things disappeared completely. This is indeed too weird, and it seems impossible to do it by human power.
"Where is the so-called demon civilization?"
Lin Yun began to search for the demon civilization throughout the star cluster.
The entire "Demon Star Cluster" is simply too huge.
Even though Lin Yun's spiritual consciousness had reached the peak of the sixth realm, he had been searching for many days but could not find the demon civilization.
It wasn't until half a month later that Lin Yun discovered a unique sun in the center of the Demon Star Cluster.
This sun emits blue light and its surface temperature is extremely high. It is the largest and dazzling among the "Demon Star Cluster". Its diameter is more than a hundred times that of the sun in the Three Realms, and its volume is smaller than that of the Sun in the Three Realms.
At least a million times bigger!
When Lin Yun set foot on this star, he couldn't help but gasp, unable to conceal his surprise.
"Can a civilization be established on a star?"
Lin Yun looked around and saw that there were densely packed buildings on the surface of the extremely hot star.
It is different from other metal buildings seen before.
Nowadays, all the buildings on this star are made of plasma flames that have been solidified and cast.
Every building is extremely huge, and the gate alone is a hundred meters high.
Not only that!
On the surface of this sun, there are countless high-tech products.
Laser weapons, plasma weapons, ball lightning, space curvature engine spacecraft, and various high-tech weapons that Lin Yun had never seen before opened Lin Yun's eyes.
There were even a large number of smooth objects that resembled water droplets, allowing Lin Yun to see the gap between technologies.
Even if Lin Yun carefully observed this drop-shaped object, he could not see any flaws at all. Even if it was magnified millions of times, to the level of elementary particles, its surface would be extremely smooth.
The hardness of this water droplet also shocked Lin Yun. Even with Lin Yun's current strength, he could not destroy this water droplet without using the power of space.
In addition, there are also some huge metal hulls that are even larger than before, displayed one after another on the surface of the sun, forming the largest super fleet in history.
The special metal that contains huge energy is piled up like a mountain, everywhere.
This has completely exceeded Lin Yun's imagination.
