1. First-level civilization: can only be immigrated and transformed between planetary systems. (such as Mars), which does not yet have the ability to colonize between star systems.

2. Level 2 civilization: It is possible to migrate between neighboring star systems, and its range of activity is about 10 light years.

3. Level 3 civilization: Able to carry out basic navigation in Hanoi.

In the galaxy, as long as you find it, you can do basic navigation. However, due to the long duration of the voyage, there are also communication restrictions. The range of activity is about 100 light years.

4. Fourth-level civilization: It can initially apply natural wormholes to carry out navigation in Hanoi. (It is very important to carry out colonization communication in the universe, but the level of civilization is also very strict, there is no difference between the level 1 level technology and water quality, for a simple example, if the level 3 and level 4 civilization fight, the level 4 civilization will make the level 3 civilization is as simple as crushing the ants all the time).

5. Level 5 civilization: You can make wormholes by yourself, and the speed of the spaceship is close to the speed of light.

6. Level 6 civilization: It can now sail between river systems, and the speed of spaceships can exceed the speed of light. Can build Star Gates. (Large artificial wormhole) 7, 7th level civilization: the highest civilization that all civilizations in the mortal realm can naturally reach.

Able to travel between galaxy clusters, (the distance between galaxy clusters is super far away, there is nothing in the middle, and there may be dark galaxies, which is very dangerous.) Level 7 civilizations also dare not sail at will. Instead of relying on Stargate, the spaceship itself can tear through space to build a temporary wormhole for space navigation). Start exploring other river systems, many of which will leave their mark.

8. Level 8 Civilization: Obtain Immortal Dao Runes when you are at level 7 Civilization, and you can only reach it by cracking some of the previous civilization with paroxysmal hairs, that is, the inheritance left by the Immortal Dao Civilization.

Being able to travel freely between galaxy clusters allows for many dangers to be detected in advance. The distance that a spaceship can travel through space can go from one river system to another.

9. Ninth-level civilization: The highest civilization that can be reached in the mortal realm, it must reach the eighth level civilization with the help of the previous major breakthrough of the Immortal Dao civilization to break through to the ninth level.

It is possible to travel between superclusters. The degree of civilization has been designed into the realm of time and space. The spacecraft itself uses space folding technology. The spaceship is small, but inside it is like another world. The defense is amazing, the time to travel through the wormhole is fast, and the spatial ripples generated are also small. It's like teleporting. The blink disappears, and the blink appears.

10. Tenth-level civilization: All the races have ascended to the fairy world, which is also a legendary immortal-level civilization, which can be found in the universe, can create space, and can discover other parallel spaces.

11. There are only eleven, twelfth, and thirteenth levels of civilization in the fairy world.

12. Fourteenth and above have not yet appeared
