Chapter 231: Crisis (1)

The development of scientific and technological civilization, with the improvement of the level of science and technology, the energy problem has become more and more a bottleneck restricting the progress of civilization, many civilizations are unable to solve the problem of higher energy, and finally the development of civilization has encountered the coolest, and finally there are advanced scientific and technological theories but can not be supported by advanced energy sources, and finally have to hate.

The energy used during the civilization period from level 4 to level 7 is all energy crystals. The fourth-level civilization uses C-grade energy crystals, which are energy crystals formed by the intense energy of the supernova explosion through the extreme environmental compression of the supernova explosion at the moment of the supernova explosion. For the electromagnetic technology that a fourth-level civilization has access to, this level of energy level is completely sufficient.

However, after the civilization has developed to the fifth level, the demand for high-level energy has skyrocketed, because the technology of the fifth-level civilization has affected the scope of space. Both the Jump Engine and the Subspace Communicator need to have an effect on space, and during this period, the energy intensity contained in the C-class energy hedron is not enough. It's as if it only takes five volts to light a light bulb, but to start an electromagnetic turret, the voltage required can be hundreds of thousands. And the spar deposits produced by the supernova explosion simply do not meet the requirements. Therefore, it is only possible to use compression to forcibly increase the energy level of the energy crystal.

Starting from the fifth-level civilization, with the improvement of the level of science and technology, the influence on the space is increasing, and the energy level of the energy spar is also getting higher and higher. From A to S, then to SS until you go up to SSS energy crystals. But this is already the limit of the use of energy crystals.

From the A-grade energy crystal compressed from the C-grade energy crystal, the exchange ratio is 1,000 to 1, and the energy recovery rate is about 170%. From grade A to grade S, the exchange ratio was 100,000 to 1, and the recovery rate suddenly dropped to 135/100, and when it came to the SSS-grade energy crystal, the recovery rate actually dropped to single digits.

If it is compressed again, it will not be able to receive a higher grade energy spar at all, and the excessively high energy will cause the spar space to be unstable, and eventually it will collapse directly. Therefore, the development of energy spars to SSS level is already the limit.

When the civilization has developed to the eighth-level civilization stage, the energy required can no longer be obtained through the energy crystal. During this period, advanced civilizations obtained energy by extracting energy directly from giant stars. At that time, the size of the star was too large, and the energy produced per unit of time was also stable, and it was simply impossible to meet the requirements of use. So new ways of extracting energy were discovered.

Energy is obtained through material annihilation, or it is directly broken to extract the milder secondary energy in the space storm to meet the energy demand, or even more, it is directly extracted by extracting a small cosmic space decay energy to obtain a huge amount of energy. The scientific and technological means behind it are already the creation power of god-level civilizations, and ordinary eighth-level or even ninth-level civilizations can't reach that level at all. The vast majority of Rank 8 civilizations are still empowered by powerful annihilation reactions. This requires a higher density of objects as a fuel source, and the most dense stars in the universe are undoubtedly neutron stars and black holes.

To measure the level of development of an eighth-level civilization, you can guess one or two by looking at their fuel sources. In the early civilization of the eighth level, the annihilation reactor is not up to par, and only the relatively safe white dwarf star can be used, and the more mature the technology, the denser the star will be.

Chen Peilin obtained those one-time dimensional weapons from the ancient human race, and just to activate them, they needed to annihilate a neutron star or a small black hole to provide energy support. There are also warships from the Pan civilization, just to maintain a minimum level of operation, it is necessary to consume the mass of the neutron star at all times to extract a huge amount of energy, if you want to carry out high-intensity operations, you must fill a massive black hole in the energy core of the battleship.

At the extreme edge of the universe, many galaxies have evolved to their limits, and their central black holes are so massive that many advanced civilizations will go there to find black holes to store and use as energy sources. As for why black holes in galaxies like the Milky Way are not bothered, this involves an agreement between advanced civilizations.

Destroying the balance of a stable river system is not allowed by groups of advanced civilizations, because each civilization has its own home galaxy, and no one wants the river system from which their civilization was born to be destroyed by others, which is not much different from digging up people's ancestral graves. In addition, the mass of the black holes in the evolving river system is generally relatively small, and a large amount of material is scattered throughout the river system, which is not very useful.

Therefore, generally speaking, no one wants to touch other people's scales to do such a thing, who knows if there has been a special NB antique-level civilization in the galaxy they want to destroy, usually inconspicuous and watertight, when the time comes, they will come out and chase themselves fiercely, and find someone to cry to. This kind of thing has happened many times in the long history of cosmic civilization, and a few times it has caused a sensation in the entire high-level civilization circle.

As for the energy consumption of an artifact like the Starry Sky mothership, it is even more terrifying, and its energy center is directly extracted from the entire small universe to supply energy. The small universe that Chen Peilin discovered at the beginning was just the "fuel" of the Starry Sky in the final analysis, and since Chen Peilin now regarded it as the ultimate shelter for human beings, of course it could not be wasted at will. Therefore, the day of starting the Starry Sky is far away, unless it is a life-and-death escape for life, otherwise, a little shrinkage of the small universe will make Chen Peilin's heart bleed. Moreover, who knows if the small universe will collapse in the process of extracting energy? Chen Peilin must not take this risk.

Wilson stood in the command seat with a frown, looking at the defensive situation map in front of him. On the holographic projection, dozens of small green dots flicker on and off, and it won't be long before one green dot disappears. Each speck represents a sixth-level integrated fleet. There were more than 300 green dots in the original, but now there are only a few dozen left in front of them, and the remaining fleet has already been exhausted by the flagships of the defensive campaign for a few days, and has become a wreckage and ruins scattered in the starry sky.

On the other hand, directly opposite the dozens of green dots, hundreds of scarlet points of light are constantly flashing, and this number is still increasing every moment, and it seems that the entire projection is about to be covered. Each of these red highlights represents the assembled fleet of a glorious empire. As for those dozens of particularly bright spots at the enemy's front, each one was a formidable seventh-tier fleet. The reason why the defending fleet retreated so quickly was largely due to them.

"The enemy has fully established itself, there is no need to defend it, let's retreat to the next stargate," Wilson ordered calmly.

"But General, the next stargate is the last line of defense, and if it is lost, even if the enemy does not pass through the stargate, a few jumps can directly advance to the Peach Blossom Spring. And we've only been defending for less than twenty hours, isn't it too fast? The confidential secretary said with a bitter face.

"There's no need to defend here, just a waste of what little precious fleet we have left. Wear my orders, retreat to the next stargate," Wilson said in a firm tone.

"Yes!"

"Dut...... Honk...... Honk...... Loud sirens echoed throughout the fleet............
