Biological civilizations were different from technological civilizations.
The advancement of technological civilizations relied on technological development, while biological civilizations relied on individual evolution.
However, individual evolution required the evolution of the energy in the body. Simply put, it was to change from one form of energy to another.
The individuals of technological civilizations also had two individual evolutions.
The first was to convert biological energy into dark energy, which was the so-called dark energy user.
The second was to convert dark energy into energy closer to the origin, which was the source of life that Lin Aotian mentioned. The Alfate Civilization evolved into a pure source of life energy through this conversion.
In fact, this kind of evolution was also something that technological civilizations had to go through. It was not like what Lin Aotian said, that they could not become a god-level civilization because they evolved into energy.
The reason why the Alfate Civilization could not become a god-level civilization had nothing to do with this kind of evolution. It was purely because they took the wrong technological path when they were a level-9 technological civilization.
Of course, this was not impossible to solve. As long as they overturned all the technological theories and started over, they still had a chance to become a god-level civilization.
However, this was like breaking down and starting from scratch. Most civilizations would not be able to accept this.
Another reason was that the Alfate Civilization had never known that this was the problem, so they naturally would not do this.
The situation of biological civilizations was somewhat different. After an individual reached level-10, which was a half-dark energy half-black cavity state, if they wanted to go further, they would have to completely convert into black cavity energy.
As long as this step was completed, the universe's creatures would completely become black cavity creatures. Even if they left the universe, they would still be able to survive in the black cavity.
However, it was not easy to do this step. The most important problem was that to completely convert, they would have to have a large number of dark energy crystals. After all, within the universe, dark energy crystals were the only way to obtain black cavity particles.
The amount of black cavity particles that could be obtained through the dark energy spring was very small, and there was also the control of the five Universal Civilizations.
Therefore, Garen did not have the opportunity to obtain too much to support his complete evolution.
This was also why Garen had been stuck at the peak of level-10 for tens of thousands of years and could not advance.
However, all of this was because of the special ability that Ipnos had obtained after advancing to level-10 …
It had changed!
Perhaps Ipnos himself did not know that this ability he had obtained after advancing had directly opened a path to heaven for all biological civilizations in the entire universe.
What was a dark energy crystal?
In the black cavity, the particles flowed into the universe through the dark energy spring and were enveloped by the instinctive energy of the universe, thus forming a crystalline state.
To be honest, the efficiency of the dark crystal was very low.
After all, ninety-nine percent of its components were dark energy matter, and less than one percent were black cavity particles.
Then, in the black cavity space, was there a purer black cavity matter?
There was an answer!
In the Black Cavity, there was a special space that countless god-level civilizations called the interlayer. These spaces all had a similar characteristic, which was that they would constantly absorb the particles in the Black Cavity, and after a long period of time, they would be nurtured into a special crystal.
Other than the outermost layer, the interior of the crystal was completely composed of black cavity particles.
Therefore, this interlayer space was like an oil field, a strategic resource. Countless god-level civilizations even …
They fought over the development rights of certain mezzanine spaces.
It was easy to imagine how important it was!
In fact, every individual of a biological civilization would evolve a new organ after becoming a Rank-10 creature.
Take Garen for example, the organ he evolved was like the black cavity mechanism created by technological civilizations. It could be used to directly open the black cavity channel, just like how Garen sent Haig from Nerkeia directly to Wills.
However, Garen was still in the form of half black cavity and half dark energy after all. The black cavity energy in his body was not enough to support this operation. This was also why Garen was weak for a period of time after opening the black cavity channel and sending Haig over.
After Ipnos evolved to Level Ten, a new organ was also born in his body. Relying on this organ, he could directly open a channel, a channel that connected to the black cavity interlayer space outside the universe.
At the same time, the interlayer space that Ipnos was connected to happened to be close to the Azure Dragon Universe and had not been developed by other civilizations for the time being.
As for the diamond-like polyhedron that Ipnos fished out, it was called the black cavity crystal by the god-level civilizations.
After discovering the nature of this strange crystal, Garen immediately asked Ipnos to get more of it, so …
After spending a few days, Ipnos directly got hundreds of black cavity crystals from the interlayer space.
With the help of these black cavity crystals, Garen quickly broke through the last barrier that hindered his evolution and began the final evolution!
However, this evolution did not seem to be easy, so much so that Garen had been sleeping for a few months and had not shown any signs of waking up.
While Ipnos was happy for Garen, he also had a lot of worries.
-----
Just as Garen was sleeping, in the known universe, the interstellar version of the "express delivery" service launched by the Federation was also in full swing.
In a short span of three months, almost all civilizations above Level 7 were assigned at least one Milta device.
Just as Lin Zhen suggested, the first thing these civilizations did was to protect their own capitals. If there were more installations, they would also protect several other important areas. Then, they would prioritize moving the elites of the entire civilization to the safe zone.
Moreover, during this process, they had verified the effectiveness of the Milta device countless times.
After all, Faern was looking for food every day. In these three months, he had also attacked many civilizations.
Although many civilizations still lost almost ninety-nine percent of their population due to Faern's attacks, due to the appearance of the Milta device, the population in the safe zone had escaped the disaster, protecting the most elite of the civilization.
As long as this elite group was still around, the civilization would be able to recover very quickly in the future.
As for Fain, he naturally noticed this as well.
Although in the beginning, he thought that the appearance of this civilization was an accident, after attacking many civilizations, he understood …
It should be a civilization that had developed a device that could resist him.
To Faern, this was …
Not a good thing!
