Speaking of the Mirror Domain, we must first start with a notorious atlas from the Ancient Era.

It is rumored that a set of atlases called "Atlas of Mountains and Seas" circulated in the ancient era of the source domain, but it is a pity... Those who were lucky enough to see the atlas ended up being unlucky.

Insert a perfect replica of the old version of the book-chasing artifact that can change the source of the APP--source change artifact.

Unfortunately, it is not because of life and fatigue that he became ill, but that the martial arts powerhouses who had seen the atlas ended up in a state of sometimes sober and sometimes insane.

If you dream of the picture in the "Atlas of Mountains and Seas" in the middle of the night, foaming at the mouth can be regarded as the favor of the sky, and the guy who can't bear the impact of the atlas closes his eyes sideways, or jumps off a cliff to commit suicide, or hangs a beam and there are many others.

Because..."The picture depicted in the Atlas of Mountains and Seas is a completely different scenery compared with the mountains, rivers, seas, and lakes in the source region.

According to the depiction in the atlas, the humans in the atlas are not much different from the normal humans in the Reality Source Domain, they also have a nose and a mouth, two eyes and two legs, but those guys are all dressed up to the waist, and there is no difference between men and women.

Of course, it is not difficult to understand this kind of thing in the source domain, it is said that once a son of heaven and a courtier, if any guy in charge of real power is playful, it is not impossible to advocate this kind of cloaking style.

But aside, those guys' eyes are a single color, whether they are white or pupils. There are more dazzling reds, but there are also obsidian colors like jewels and azure blues like ice.

This is true for everyone.

Seeing this, the martial arts scholar who saw the long hair and felt that it was due to interest had already muttered in his heart, these guys said that they were human beings, but no matter how you look at it, they are more like a deeply hidden race.

It's not uncommon to see one, but if there are thousands of the same, it's chilling.

And these humans are just one of them.

Looking at the picture album again, the world that those guys live in is a completely monotonous world of color.

The mountains are lush and uncluttered, like the green prints in the city's dye mills, the water is bloody, and the beasts that run in that world are strange creatures that have never appeared in the source domain.

The white tiger fluttered its wings and soared into the sky, but its tail was a clearly visible golden python tail. The sand cats ran in the gold-grained desert, but before they had run more than halfway along a strand of sand, the desert behind them was covered with the teeth of these saber-toothed tigers

There's not much left for the sand cat to devour. It seems that pointing to a piece of the sky, these kittens who are only the length of a human arm can gnaw on them.

If this kind of cat that devours gold and silver is thrown into the battlefield before the war starts, I am afraid that in a wave, these little things can eat the opponent into a square of bones.

However, whether it is a single long-haired human being, or a beast with different forms but full of destructive power, a tangible disaster is coming, in the final analysis, there is a corresponding defense, but if the thoughts that are suppressed in the heart are not dredged and resolved in time, it will naturally be depressed and make people go crazy in the long run.

After the appearance of the "Atlas of Mountains and Seas", all the martial arts powerhouses who have watched the atlas are all suspicious, these things... What kind of creatures are there?

Unknown things are strange and terrifying after all, and the martial arts powers in those source domains are no exception, so the appearance and disappearance of the "Atlas of Mountains and Seas" is a mystery, and they can only pray for a little solace in seeking knowledge elsewhere.

Flipping through thousands of ancient books, the power of source domain martial arts finally found a vague statement... Mirror Domain.

It is not known who proposed the word 'mirror domain', but it is appropriate to use it to set off this "Atlas of Mountains and Seas".

What is the mirror domain? The ingenuity lies in the word 'mirror'.

There are two interpretations.

One is that it is both true and false, simply put, the person who looks in the mirror is real, and everything in the mirror is only what is presented in front of the mirror.

The source world is real, and everything in the "Atlas of Mountains and Seas" is a kind of mutated reverie in the mind of the painter of the real world, and the atlas flows in the world, but the evil means of that guy.

Second... The mirror domain is another 'source domain' that corresponds to the source domain of reality.

After all, many people are happy to see good things, even the powerhouses of the level of the Immortal Ice King and the Southern Desolation Python Lord don't want to see that they don't even understand, and even extremely panicked. But "Atlas of Mountains and Seas" brought them the most real ideas, but it couldn't deceive them.

They all have an impression of the "Atlas of Mountains and Seas", which seems to appear inexplicably, and even the colors are a little monotonous, but every picture in the album seems to be carefully depicted.

Not only meticulous, but also extremely delicate, as if... Draw yourself yourself?

If it weren't for the flowers and plants in the atlas, everyone and everything would be familiar to the extreme, there would be something in the world

Who can paint such a detailed scene?

Moreover, since the primeval chaos differentiation tens of millions of years ago, there have been few strange people and strange places in the vast source domain? It's just that they used to be alone, and in the eyes of outsiders, they were just a mutated body to look at refreshingly.

In fact, as far as the matter of the Mirror Domain is concerned, after the Holy Gu retreated to the Dao Soul Realm to recuperate ten thousand years ago, when the Lord of the Flame Heaven came forward to leave the Ten Thousand Beast Land, a martial arts master inquired about this matter.

It was really not for nothing that the martial arts master was able to talk about this one thing, after the Holy Gu attacked the Central Domain, they withdrew all their families in the defeat and retreat of the two realms of the Righteous and Demon, and only then did they know that they were once a branch family of the prestigious auction family in the Source Domain.

And the most bizarre and bizarre thing recorded in the classics of the ancient auction family is that he once took over the auction of the "Atlas of Mountains and Seas" in the ancient era, but unfortunately the "Atlas of Mountains and Seas" has not been auctioned off, and the album that cannot be torn apart by a strong man who has crossed the peak of the beginningless heavenly product with half a foot is strangely incinerated in public.

That was the last time the Atlas of Mountains and Seas appeared in the Source Domain.

"Mirror Domain, heh, you are true and false in the mirror, and how can you distinguish the real from the fake outside the mirror?"

Ten thousand years ago, the Lord of the Burning Heavens replied.

In a word, the parties in the source domain have been guessing for 10,000 years, and they still don't know how to understand it to this day.

I don't know the solution, and if I solve it, I don't understand it.

After all, as a rare atlas that suddenly appeared and circulated in the hands of a very small number of martial arts masters, the "Atlas of Mountains and Seas" did not have much far-reaching impact on the vast majority of martial arts scholars and hundreds of millions of ordinary people in the source domain.

Moreover, there have been some rare alienated beasts and alienated human bodies in the Source Domain, but these strange existences that were suddenly exposed to everyone's sight did not harm anyone.

With only these sporadic memories and the inexplicable "Atlas of Mountains and Seas", it is not inappropriate to crown the so-called mirror domain as the most secret of the six secrets, but it is inevitably far-fetched.

And even if the Mirror Domain really exists, what can the passage connecting the Mirror Domain and the Reality Source Domain be open to the heavens and the earth? When the sky falls, there is still a high top, not to mention what the ambitious Qinglong Emperor will do, but the Lord of the Burning Sky and the Lord of the Hidden Mansion, the two supreme giants of the two realms, can still allow the creatures of the Mirror Domain to make a big splash and endanger the world?

They don't eat radishes salty and don't worry about it.

This mirror, come and look at it again.
