Time is the most important thing for each of us, but in the eyes of scientists: time is just a virtual concept, in order to confirm this, they have made a lot of experiments, and they have also come to a lot of conclusions, and the final conclusion is that in the universe, time may no longer exist.

The essence of time is to measure the change of the surrounding things, although it is impossible to accurately sense his existence, but in human cognition: everything in the world is constantly changing over time, and some people even want to stop time with the help of advanced technology.

This is simply 'unattainable'!

Obviously, time is more inclined to the subjective consciousness of human beings, and it is the best condition for us to explore the external process, because it does not exist in itself, starting from the most primitive knotted rope records, human consciousness of time has begun to slowly become clear, and the greatest significance of its existence is to help us better record and discover.

It is this subjective consciousness that limits our human thinking.

As Newton once said, time is virtual, and its existence is similar to mathematical formulas, and it is also for better measuring and calculating the information of the universe.

The four-dimensional space we understand is actually to add an additional dimension of time on the basis of three-dimensional, but in fact, we cannot intuitively see the existence of dimensions, and time is at best the axis in the calculation process.

To put it simply: time is actually created by humans!

If there are other civilizations in the universe as we know them, do they also have the concept of time in their concepts?

As we all know: when a line is formed, a one-dimensional world is formed; Lines move into planes, which is a two-dimensional world; The surface moves into a body, and it becomes the three-dimensional world in which we live; The body moves into multiple bodies, which is the trajectory of our three-dimensional world, which is the four-dimensional world.

If we want to understand the world of thought, we should not be in a hurry to explore the universe; In fact, human beings themselves are a small universe, as long as you can penetrate your body, why not understand the universe?

This is the ultimate meaning of 'looking inward'!

The universe is so big that human beings cannot imagine. Human civilization has developed for nearly 200,000 years, and the four ancient civilizations better reflect the continuous development of human beings in the social stage.

So, is the universe also its own civilization?

As early as 1964, a Soviet writer named Kardashov envisioned a cosmic civilization. So how exactly is the universe divided into hierarchical civilizations?

To understand the hierarchy of civilizations in the universe, we must first understand a term: the 'Kardashov index'.

The Kardashov Index, which is the level of development of extraterrestrial or human civilization that cosmologists classify as may occur. It was first proposed in 1964 by the Soviet astronomer Nikolai Kardashov: there are three designated classifications: high, medium and elementary.

And this criterion is based on the energy available to civilization, as well as a certain degree of space activity.

Elementary civilization: home star civilization (there is no so-called satellite system, this level of civilization takes the home star as the core, let's call it the home star civilization); Medium-sized civilization: planetary system civilization (the solar system is a planetary system, and a planetary system refers to a collection of various celestial bodies orbiting a star, including planets, moons, asteroids, meteoroids, comets, and cosmic dust); High-type civilization - stellar civilization (the Milky Way is a star system, and the star system or galaxy is a collection of countless celestial bodies (and stars) that can emit light and heat themselves)

Then, using this as a reference, the known universe was divided into twelve levels of civilization.

And our earth civilization, if the standard is in order, can only be rated as: zero-level civilization; Because, with the current capacity of the earth, it can only be equivalent to 0.75 first-level civilizations: there are space station technology, space technology, and the primary stage of various physical theories (the primary stage of human socialism + the primary stage of capitalism).

Tier 1 Civilization: Can migrate between planetary systems. Remodel. (e.g. Earth, Mars), but does not have the ability to colonize between galaxies.

Level 2 Civilization: Able to migrate between adjacent star systems, within a range of approximately 10 light-years.

Level 3 Civilization: Able to perform 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.

Level 4 Civilization: Able to preliminarily apply natural wormholes for navigation in Hanoi. (It is very important to colonize communication in the universe, but the level of civilization is also very strict, and each level of technology is very different, to give a simple example: if a third-level civilization and a fourth-level civilization go to war, the fourth-level civilization will treat the third-level civilization as simple as a human crushing an ant).

Level 5 civilization: You can make your own wormholes, and the speed of the spaceship is close to the beam.

Level 6 Civilization: It can now sail between river systems, and spaceships can travel faster than the speed of light. Can build Star Gates. (Large artificial wormhole) (The primary stage of communism + the ultimate completion of the ultimate stage of capitalism)

Level 7 Civilization: Able to sail between galaxy clusters (the distance between galaxy clusters is super far away, there is nothing in the middle, and there may also be dark galaxies, which is very dangerous.) Level 7 civilizations also dare not sail at will. No longer relying on stargates, the spaceship itself can tear through space to build a makeshift wormhole for space navigation). Start exploring other river systems, many of which will leave their mark.

Level 8 Civilization: Able to navigate between galaxy clusters very freely, basically many dangers can be discovered in advance. The distance that a spaceship can travel through space can go from one river system to another.

Level 9 Civilization: Can sail between superclusters. The degree of civilization has already involved the realm of time and space; The spacecraft itself uses space folding technology; The spaceship is small, but inside it is like another world; Amazing defense...... The time to travel through the wormhole is also very fast, and the spatial ripples generated are also very small, just like teleportation, disappearing in the blink of an eye and appearing in the blink of an eye. (The ultimate stage of communism, capitalism degenerated into a colonial theocratic royal feudal society)

Level 10 Civilization: It is also a legendary god-level civilization, which can be found in the universe, can create space, and can discover other parallel spaces. (Communism has degenerated into the ultimate perfection of authoritarianism, and god-level civilization no longer needs the existence of communism).

Level 11 Level 12: (Superstring Civilization / Chen Trace Civilization) Able to create complete life, some people may think that humans can still create life now, such as: cloning. But you have to understand that this is not called the creation of life. When human beings can create souls, let's talk about creating life. The legendary civilization can sail between parallel universes and constantly create and sow life.

Seeing that Li Ming was indifferent to his pleading, Huang Xiaoxian could only close his eyes, and when he was about to face death calmly, he heard Fan Ziming, who was roaring, let out a terrible scream.

"I don't believe you're going to make a move!" Huang Xiaoxian closed her eyes and said with a smile on the corner of her mouth as if she had succeeded in her treacherous scheme. However, he pretended to be shocked and opened his eyes and said, "Thank you......"

But when he opened his eyes, he found that it was Li Ming's girlfriend Xu Manman who defeated Fan Ziming. She was dressed in a traditional light green practice uniform, wore square-mouth cloth shoes, and held a sword about two feet four inches long, with two gossip patterns engraved on both sides of the sword grid, and the outside of the gossip pattern was inlaid with eight different gemstones, and the two fish eyes were two pairs of jade, one black and one white.

Because Huang Xiaoxian had his eyes closed just now, he didn't see how Xu Manman defeated Fan Ziming; I just saw broken black shadows scattered everywhere.

The shattered black shadow wandered around, and it was not until it fled far away that it reunited into its human form again, "Ji Ji Ji~", and let out a terrible laugh: "Here comes another dessert." ”

"Edict!"

One blow hit, Xu Manman, who was originally ecstatic, never expected that Fan Ziming, who was shattered by himself, would reunite again, so he pinched the mantra with his left hand, recited the incantation, and pointed his right hand at Fan Ziming, who had just gathered into a human form, and an edict in his mouth: The jewel on the sword grid on the nine-pole sword lit up, and an invisible and substantiated sword qi shot out, and Fan Ziming, who had just reunited in human form, was in the middle.

"Ah~" Fan Ziming screamed again and was shattered.

Eat a trench and grow a wisdom, this time Xu Manman is ready, and when Fan Ziming has just gathered into a human form, it will be another yin sword qi.

So again and again, Fan Ziming was not given any chance at all. It wasn't until the tenth time later, when Xu Manman was about to use his Yin Force Sword Qi to defeat Fan Ziming again, that Li Ming suddenly said: Listen first! I have something to say. Xu Manman stopped.

After Fan Ziming reunited with his human form, the black shadow had faded a lot, and he no longer laughed as unruly as before.

"How about it? Fan Ziming, do you want to die or live?" Li Ming said with a smile from a distance.

"Want to kill me?" hehe...... Fan Ziming said unruly, but he hadn't laughed twice at the spirit body with great loss of yin power, so he coughed a few times: "Ahem~" coughed a few times.

"Sharp teeth!" Li Ming said coldly: "Man Man continues!"

"Whoosh~" A yin sword qi passed, and Fan Ziming was smashed again.

After doing this a few more times, Li Ming stopped again and asked, "How is it? Can we talk?"

"Talk about your mother's ass!" Fan Ziming, who gathered in human form, roared angrily: "You want to kill me! Dream! cough~"

Li Ming said quietly: "With Manman's strength, it is true that he can't kill you, but he can drag you down." As long as you survive a few hours, as soon as the sun comes out, it is up to you and me to decide whether you will die or not!"

"You, you, what do you want?" Fan Ziming finally wilted.

"I know you hate this injustice! But is it useful for you to be so cynical? So, Li Ming began to persuade bitterly.

At this moment, Fan Ziming also guessed that Li Ming didn't want to kill him, so he asked in a low voice, "What do you want me to do?"
