After Qing Xuan and the other two arrived on the ground, they flew out of the atmosphere before Xiaoyu turned into a big roc again. Qing Xuan, Xuan Wu and Xiao Ai stood on the back of the big roc when they saw this. Under the gaze of a group of intelligent robots on the ground, they all disappeared in a flash.

"Intruders evacuate...release the highest alert...activate the backup energy core..."

After Qing Xuan and others left, the sound of the war master's brain came from the metal tower, and then all the intelligent robots walked out of the safe houses of each building again. At the same time, the sun in the sky burst out with an energy fluctuation, and then disappeared again.

Of course, Qing Xuan and others didn't know everything in this cave, and what they didn't know was that there was actually an energy core hidden in the artificial sun. Now several people were driving the escape light and rushing to the battleship that was staying in space.

"Xiao Ai, how about it? There is useful information in this harvest, and tell me what level of their technological level is."

On the battleship, Qingxuan sat on the sofa and asked Xiao Ai. He was suddenly interested in how these technological civilizations divided the levels and how they were different from those who cultivators.

"My fellow Taoist, the main brain of the war we encountered should be the product of the third-level technological civilization. Our interstellar civilization divides technology into six development stages. Do you want to listen to it?"

After Xiao Ai returned to the main control room, she set the route according to the coordinates of the ring-yang system given by Qingxuan, flew to the sofa to answer Qingxuan's questions, and then asked.

"Well, you're talking about it. Starting from the first-level civilization, I'm not in a hurry. Just talk slowly. By the way, it's better to get some images for us to see."

When Qingxuan saw Xiao Ai's inquiry, he knew that it was probably a bit long, so he half lay on the sofa, snapped his fingers, and after a glass of spiritual juice appeared in his hand, he opened his mouth and said to Xiao Ai.

"My deity, the so-called first-level civilization is to use various energy sources on your planet. For example, there is no wind in nature, but we can artificially create wind, and other natural elements, and we must have a certain self-protection ability to be considered a first-level civilization..."

While Xiao Ai talked, he played out a series of projections, which were filled with simple technologies, mostly physical attack weapons, and did not even have the ability to fly out of space. The resource utilization rate of his own planet is less than 50%.

"The second-level civilization is to escape from gravity and enter outer space. And there is also an obvious sign that it has begun to master the basic nuclear energy application and can make bulky and uncompressed nuclear weapons..."

As Xiao Ai preached here, Qingxuan couldn't help but think of his previous life. In this way, they should be a second-level civilization. At that time, countries had long developed nuclear weapons and were working hard to detect space.

"The third-level civilization is the civilization I call the main brain of war. They have developed low-level intelligent brains, have planetary computing power, and the ability to colonize other planets. The most obvious sign is that they have the basis for mastering antimatter energy, which is the core energy technology, which can use it to capture antimatter and utilize it..."

Regarding the third-level civilization, Qing Xuan nodded clearly. This kind of civilization can rely on the intelligent brain to easily complete the data processing of a planet to launch interstellar colonization. He has mastered some abilities that are more than that of the planet, such as controlling the sun and flare bombing.

"The fourth-level civilization has perfectly controlled antimatter energy, has an intermediate intelligent brain, has a stellar level of computing power, and has begun to learn space application technology. At this time, it is easy for them to destroy a planet and have completely entered the interstellar era. Space jumping technology is the highest technology of this civilization."

After Xiao Ai explained this, the battleship was projected on the screen. This is the product of the fourth-level civilization. It has the ability to use basic space and can open wormholes to shuttle and jump.

Moreover, although this battleship was not equipped with antimatter energy cannons due to Xiao Ai's problem, it had the same quantum reaction cannon, which could fully support the highest civilization crystal of the fourth-level civilization.

"The level five civilization is that it can perfectly use the energy of space. In our interstellar civilization, it is called the power of latitude. The most representative of it is that it can easily reduce the dimensions of a star system and then restart that galaxy.

The interstellar civilization I am in is this level. The most powerful thing about our civilization is the complete void engine. It is a galaxy-level intelligent brain that can instantly destroy a galaxy without mastering space capabilities and destroy it into the turbulent flow of time and space."

When Xiao Ai talked about the fifth-level civilization, he projected a piece of starry sky that was swallowed by space. Huge stars did not even have a slight resistance, and instantly turned into powder. Until all the creatures in that space completely disappeared, the entire space was twisted again, and the planets began to rebirth, and the creatures began to appear again, but this time the creatures had become people of the interstellar civilization.

"Xiao Ai, you are sure that it is not your heavenly way of nature that has this ability, but a super intelligent brain. Have you heard of anyone who can control it? Or it has its own consciousness and is fast for you."

Qingxuan looked at the picture projected by Xiao Ai. It was obvious that the Heavenly Dao was expanding its own domain. The one who was destroyed was a relatively weak galaxy. After being destroyed, it was not the ability of the Heavenly Dao to see the ghost.

"My fellow Taoist, I have seen it. Isn't my Void Engine just copied it? But before I finished copying it, the Dream Lord took me away in an urgent matter."

Xiao Ai said helplessly that although some of the principles were copied, the usage method was not copied at all. Just the wormhole shuttle technology has been researching for more than 20 years and has figured out some things by itself.

"Okay, okay, didn't you say there were six levels? What's the other civilization like?"

Qingxuan saw that Xiao Ai had seen it, and also used a projection to project an illusory sphere of light that could not be seen. If it was reduced, it would indeed look a bit similar to Xiao Ai, so he was not worried about it.

"I divided the sixth level civilization myself, which is the kind of civilization that can perfectly utilize the power of the rules of the universe, use it to defend our galaxies, and also use it to bury the enemy. Our current civilization does not have the power of resisting foreign enemies. This is a civilization level that I only divided after seeing the Dream Lord."
