The main energy source of the first-level civilization is thermal energy, or combustion energy, there are many technologies of this level of scientific and technological civilization, machinery that uses combustion energy, explosives that use combustion power, and some preliminary use of electrical energy and nuclear energy, but it is a rocket engine that can represent the pinnacle of creation, Ariel has a sense of déjà vu, and the first-level scientific and technological civilization has too much in common with the technology of the earth.

Then there is the secondary scientific and technological civilization, making a breakthrough in nuclear energy, the core is small nuclear energy cold fusion technology, the reform of energy derives a lot of machinery using nuclear energy engines, this is a leap in science and technology, the pinnacle of creation is the Gaussian engine,

The spaceship powered by it has almost unlimited endurance within the star system, and its endurance can support it to sail out of the star system, but in fact, the second-level technological civilization cannot break out of the star system.

Cold fusion has many advantages, it is safe and easy to control, and the energy supply is continuous and stable, but these advantages are also disadvantages, and the speed of the spacecraft driven by the Gaussian engine powered by cold fusion energy cannot reach the third cosmic speed at all, so no matter how good the endurance of the spacecraft powered by this is, it will not be able to fly out of the star system!!

So the successful civilization called "Touching People" then invented plasma technology, they stored electrical energy in the form of plasma, and after accumulating full energy, they could propel spaceships to break through the third cosmic speed in one fell swoop, rush out of the star system, and become a third-level technological civilization.

After successfully becoming a third-level cosmic civilization, the touching civilization fell silent, this silence is thousands of years; it is too difficult for a low-level material civilization to break through into an intermediate energy civilization, if the breakthrough of a first-level to third-level, fourth-to-sixth, and seventh-ninth level civilization is a small bottleneck, which is equivalent to the breakthrough of the Great Sword Master from the early stage to the late stage, and there is not much of an obstacle, but if you want to break through to become a sword master, it is equivalent to the difficulty of breaking through from the primary material civilization to the intermediate energy civilization.

This millennium is defined as the Dark Ages in the history of the Touching Civilization, and although their spacecraft can break out of the star system, they cannot reach the second solar system, and the long space voyage can grind the longest-lived Touching people! Having a dormant system is not the best use, maybe the astronauts can reach the predetermined star system after a thousand years of sleep, and for the astronauts, they are successful.

But this voyage is doomed to failure for the Touches in the star system, because the Touches in the star system will not survive to the moment when the spacecraft returns in 2,000 years.

During this period, the scientific research of touching civilization did not stop, scientific research achievements bloomed everywhere, the science and technology of material civilization was used to the extreme, various technologies were transferred from aerospace to civilian and then to military, and different voices appeared in the unified touch, and the imperial alliance attacked each other.

Space battleships, space fighters, electromagnetic cannons, Gauss cannons, high-energy rays, lightning cannons, machine Qì human troops, biochemical troops, space mecha and other weapons have been on the space station one after another.

The first spaceships with crushing spaceships were the first to be phased out, dominating space for only a decade!!

Its fatal flaw is that it is too large in size and too slow in dodging, which is simply a target for the airborne weapons of space fighters, and no matter how thick the armor is, it cannot withstand the saturation attack of electromagnetic guns, Gauss cannons and other weapons.

After eliminating space battleships with flexibility and high offensive capabilities, space fighters dominated space for 300 years before being eliminated by new technology, and smaller machine units appeared on the stage of war, equipped with biochemical warriors, and charged without fear of death, like locusts, which is simply a nightmare for all space warriors.

But the good times didn't last long, when the two warring sides basically eliminated the space fighters, the machine Qì and the cyborg soldiers had a large-scale mutiny, they took away the home planet of the empire and the alliance, although not fatal, but it hurt the vitality of the empire and the alliance, so the two forces entrenched in the planet for hundreds of years.

For hundreds of years, the empire and the alliance were divided and merged, and the machine qì people were inextricably fought, until the advent of the humanoid space mecha that evolved from space fighters countless times, and the touch civilization really grasped the advantage, and after a protracted counteroffensive, it finally recaptured the home planet and laid the foundation for becoming an intermediate energy civilization.

At that time, a thousand years have passed, after this lesson, after thousands of years of scientific and technological accumulation, the touching civilization that has survived the crisis invented quantum acquisition technology, which is an energy revolution, quantum is ubiquitous, and it has the characteristics of affecting space stability, touching people civilization found the right direction, developed curvature navigation technology, and realized spacecraft and other speed of light flight, making space exploration possible.

The touching civilization has officially become a fourth-level scientific and technological civilization, and has entered the stage of steady development of science and technology.

After the breakthrough progress of energy technology, after hundreds of years of exploration and knowledge accumulation, they discovered the electron acquisition technology on the quantum basis, officially replaced the cold fusion energy supply system that was slightly backward for curvature navigation, and directly extracted electrons from nature as energy to drive the curvature engine.

Subsequently, nearly a thousand years later, a series of revolutionary technologies such as photon acquisition technology were invented, and the touching energy civilization developed to the peak of the sixth level.

In fact, the theory of space jump was put forward by scientists as early as the fourth-level civilization, but it has never been possible, and at that time, the touching civilization could not provide the huge energy required for space jump.

After the civilization has developed to level six, the space leap technology does not have much technical difficulty for the touching civilization.

After the development of energy civilization reached its peak and the space leap technology was applied to spaceships, the touching civilization entered the era of river colonization, and the development of science and technology once again entered a long period of accumulation.

According to the history of the Touching Civilization, during this period, the Empire and the Confederation of the Touching Civilization were fully aware of the danger of civil strife, and developed peacefully with each other, completing a crucial transition.

In fact, the reason why the sky did not fall apart again is very simple, the river system is very large, the wild planets that can be colonized are constantly discovered, the rich resources have alleviated the tension and conflict again and again, and the lessons of the dark age of the third-level civilization period have indeed played some warning roles.

This time the accumulation of knowledge is very long, so long that there is an illusion that science and technology have developed to the peak of the touching civilization at that time, and it is difficult to break through vertically, and the technology of touching the civilization has developed horizontally, and various technologies have been invented and applied to all walks of life.

The advanced technology used in spaceships has gradually transitioned to military and civilian use, and the Savage Survival Device is the product of that time, but the Wild Survival Device of Red Cloud is not an old antique produced at that time, but a breakthrough in the Touching Civilization to become a seventh-level spiritual civilization and then added to the seventh-level civilization technology manufacturing.

During this period, the exploration and cleanup of the barbarian planet was the main direction of the use of force by the human civilization, and the primary humanoid mecha manufactured during the period of the third-level material civilization was redesigned and redesigned, and in the end, the humanoid mecha only maintained its prototype in two aspects;

By the time the Touching Civilization found the opportunity to advance to a high-level spiritual civilization, the design of a series of mechas, which were later named Intermediate Humanoid Mechas, had been fully matured and could handle the combat requirements of any Savage Planet.

As a result, the Touchman Civilization was invincible in the river system, until one year when their exploration reached a wild planet at the edge of the river system, which was later named Auritus, the invincible mid-level humanoid mecha finally suffered a setback, and the pilot of the mecha suffered a devastating blow to be precise.

Civilization has developed to the sixth level, and the strengthening of the body by the touching civilization has reached the extreme, not only has the national enhancement been realized, but the strengthening and longevity factors have also been written into the genes, and the lifespan has been extended to more than five hundred years, and the pilots of the intermediate mecha are the best among them, and they have almost reached the realm of being able to survive in space for a short time after the second strengthening.

Such a powerful warrior, sitting in a nine-meter-high mecha, has a double layer of physical armor and energy shield, not to mention foolproof, it is difficult for them to get injured before the mecha is destroyed.

It is under this cognition that the all-round mecha that entered the exploration of Qishenxing has gone and returned, and the incident gradually escalated, until it rose to the strategic level, and the touching civilization found that there was still the existence of spiritual civilization above the material civilization and energy civilization, and even based on some information found by Qishenxing, a conclusion that shocked the entire river system was inferred, and there was a god-level civilization above the advanced spiritual civilization.

This is a great impact on the touching civilization that has been stagnant in science and technology for 10,000 years, and there is no need to elaborate on the turbulence, but in the end, the touching civilization successfully completed the transformation from the sixth-level civilization to the seventh-level civilization, the seventh-level civilization is a spiritual civilization, and the Qishenxing was the actual field of the ninth-level civilization that tried to march to the god-level civilization, and all kinds of signs show that they failed!!

And the price they pay is to touch the root of the turmoil of civilization, that ninth-level civilization has mysteriously disappeared!! seventh-level cosmic technology civilization can already dominate a river system, what power can make a ninth-level civilization stronger than the seventh-level civilization perish????

There is no doubt that the god level is a kind of taboo existence!!
