The next moment, Ling Yan slashed down with a sword!

Wherever the giant sword went, the surrounding space began to rapidly collapse.

Obviously, this sword has exceeded the endurance limit of this secret realm.

"puff!!!!"

The next moment, without any obstruction, the long sword swept across the Ice and Fire Demon Lord in an instant!

At this moment, the body of the Ice and Fire Demon Lord instantly turned into gas.

-10 Jing (fatal blow)

A huge black damage value rushed into the sky at this moment.

The huge damage value directly covered the entire sky and earth.

Overall, this sword is certainly not as terrifying as the previous one, but it is more than enough to kill the Ice and Fire Demon Lord who has not been strengthened in seconds.

[Ding... Congratulations to the player for successfully killing the Saint King-level BOSS: Ice and Fire Demon Supreme!

You get experience points: 10 million Jing, you get star source: 10 million (locked)]

[Ding... Congratulations! You've killed the ultimate boss in the secret realm with one strike. You've obtained Level 3 permissions for this dungeon!]

Soon two prompt sounds were heard.

The prompt sound immediately made Ling Yan raise his eyebrows. Level three authority? Yes, you can get level three authority if you kill the ultimate BOSS alone and instantly!

The third-level authority of this secret realm is the same as the third-level authority of the previous copy. It can increase the explosion rate, reduce the explosion rate, and also improve the strength of those who come in.

This is almost equivalent to reducing the difficulty of the strategy for this copy a lot.

However, Ling Yan estimated that even if it was lowered so much, no one in the Milky Way would be able to conquer this copy.

After all, this Saint King-level BOSS is really too terrifying.

"Apocalypse, continue, start the next copy!"

Thinking of this, Ling Yan continued to speak to the void without hesitation.

[Ding... Accepting the command! ]

………………

In the next two days, Ling Yan was madly brushing the Ice and Fire Demon dungeon.

Every time you refresh, Ling Yan's passive level will increase!

At the same time, you can also obtain a large amount of red equipment and materials.

………………

………………

However, when Ling Yan was having a great time, something in the universe was in turmoil.

Tianyan Star Region! An advanced star region civilization! The Milky Way is within the domain of this Tianyan Star Region.

The civilization levels in the universe are strictly divided!

The lowest level is those civilizations that have not flown out of their own planet. This kind of civilization is called primitive civilization.

Once this kind of civilization is discovered, its fate is almost certain to be exterminated.

Of course, if you are lucky and find that their advanced civilization is the same as this primitive civilization, you will be pulled into the advanced civilization.

However, there are also many civilizations that were discovered by civilizations of the same race and were still colonized and massacred!

And above the primitive civilization is the galactic civilization!

Galaxy civilization, the lowest level of low-level galactic civilization needs to develop all the planets in its star system before it can be called a low-level galactic civilization.

Some powerful low-level galactic civilizations even own thousands of star systems as their territories, and the number of planets they rule over reaches tens of thousands.

Above the low-level galactic civilization is the intermediate-level galactic civilization.

An intermediate galactic civilization needs to rule over at least 100,000 life-bearing planets, and the number of star systems must reach 10,000.

Advanced galactic civilizations above this level need to have more than 1 billion life-bearing planets.

At the same time, it rules over an independent galaxy, such as the Milky Way.

Only this kind of civilization can be called an advanced galactic civilization.

Now all civilizations within the Milky Way can only be regarded as intermediate galactic civilizations!

Because although each of their top civilizations has hundreds of millions or even billions of planets with life, no civilization has yet completely ruled the Milky Way.

Only by completely destroying other civilizations can one advance to an advanced galactic civilization.

Above the advanced galactic civilization is the top galactic civilization.

This kind of civilization is actually similar to advanced galactic civilization, except that the number of life-bearing planets it needs to rule needs to reach more than 100 trillion!

As for independent galaxies, it depends on the size of the galaxy. Some super galaxies have tens of trillions of life-bearing planets.

That is the number of dozens of Beijings!

Therefore, one only needs to rule such a super galaxy to be called a top galactic civilization.

If there were no such large galaxies, we would need to rule over multiple galaxies, and eventually the number of planets with life would reach at least 100 trillion!

And above the top galaxy civilization is the legendary star field civilization!

The star field is above the galaxy.

To become a low-level star field civilization, it is necessary to have at least 1 million high-level galaxies and hundreds of top-level galaxies within its territory!

Therefore, in the weakest star field civilization, the number of planets with life has reached at least 1,000 planets!

Some powerful low-level star fields even reach hundreds of thousands of Jing!

Only when the number of planets reaches more than 1 million can it be called an intermediate star field!

As for the advanced star field, it needs to be ten thousand times the size of the intermediate star field and have a total of 10 billion life planets.

The Tianyan advanced star field is considered to be upper-middle class among all star fields!

Therefore, the number of planets with life has reached a terrifying 30 trillion.

Unfortunately, the size of a top-level star field needs to reach a full 100 trillion, or 100 billion, of life-bearing planets to become one!

Therefore, the Tianyan star field still has a lot to go wrong.

But it is undeniable that the Tianyan star field is huge and terrifying, which is unimaginable to almost any civilization in the Milky Way.

Precisely because it is so huge, there are a large number of galaxies in the Tianyan star field. Because their location is too remote, they have not been developed to this day!

Of course, these civilizations are naturally under the surveillance of the Tianyan Star Region, such as the Milky Way.

It’s just that the technology, observation perspective, and everything else in the Milky Way have been blocked. Therefore, for countless years, the civilization in the Milky Way has no idea whether there are other civilizations outside the Milky Way!

Because the civilizations in the Milky Way cannot sense the existence of any other civilizations in the outside world through telescopes or other monitoring equipment, all the monitored planets are like dead stars.

This is the technological blockade that higher-level civilizations often use against lower-level civilizations.

After all, no one would want some low-level civilization to peek in every day.

However, surveillance is surveillance, and no one cares about a small galaxy that is still in the midst of a civil war.

Of course, as a powerful civilization in an advanced star field, the Tianyan star field has a very large number of races within its civilization.

These races and civilizations were all brought under the rule of the Tianyan Star Region.

Although they are all under the rule of the Tianyan Star Domain, they can have their own civilization servers and civilization leaders.

Just like other countries under the United Nations.

Of course, the Tianyan Star Region is not like the United Nations that can only talk big. The Tianyan Star Region has the most terrifying combat power and the most vast starry sky.

If a real war breaks out, he can single-handedly challenge all civilizations in the territory.
