He wants to explore this world, but he is worried that the strong people in this world will be hostile to him, so it is better to be cautious.

At this moment, he is like a group of people who have just crossed over to the martial spirit realm.

Han Yun returned to the top of the mountain, sat down again, and asked,

"System, what kind of world is this? Isn't it another universe?"

[This is the main universe, not the other universe.] 】

"The main universe? Am I crossing again? How could it be the main universe? We're in another big universe? Isn't it the world of Emperor Xiwa?"

[No, this is the negative plane, the negative plane of the Nine Realms. 】

"I don't understand, explain it in detail."

[Received, everything in the world has two sides, yin and yang, there is yang, there is yang, there is a positive plane, there is a negative plane.

For example, the world in which Emperor Xi and Emperor Wa are located is the positive plane in which they are located, and that's how they call them the universe.

Their positive plane has an endless universe, the origin plane, the high spirit plane, the middle spirit plane, and so on, and the plane opposite to them is called the negative plane.

The race of the negative plane is completely different from that of the positive plane, and the race that is special to it is called the demon race, also called the negative plane demon race! 】

"Demons? Is it the demon clan that once invaded the martial spirit world? Those demon corpses?"

[Yes, those demons are from the negative plane of the Xihuang universe.

And the place we are in now is the negative plane of the Nine Realms, which is the opposite of the Nine Realms in different time and space.

This is different from the Nine Realms, the Nine Realms is the continent world, and this is the Galaxy World, there are various civilizations in this world, their cultivation systems are completely different from the positive plane, and the specific situation needs to be seen by the host himself.

There are also native demons in this world, but unlike the demons who invaded the martial spirit realm, the demons there are demons from the Xihuang plane, not the demons from the negative plane of the Nine Realms, so the cultivation system will be different. 】

"Okay, okay, I don't care what kind of world this is, and I don't want to know how the people here and other civilizations cultivate, I just want to know now, how do I go back?"

[The system doesn't know, because the system can't perceive the direction of the Nine Realms, and doesn't know where the Nine Realms are, and the system only has the information of the positive and negative planes of the Xihuang universe.

Over there, the positive and negative planes are separated by the Sea of Bitterness, the terminus of all abandoned universes.

However, the rules of the Nine Realms and this galaxy universe are completely different from those of the Xihuang World, and there is no bitter sea, so the system does not have any information about this galaxy universe, and the system also needs to continue to learn and try calculations to know.

What is certain is that this is not a different universe, the other universe is based on the Nine Realms, and you only need to find an exit to return to the Nine Realms.

This world is completely different from the Nine Realms, it is the opposite of the Nine Realms, just like a mirror, one is inside the mirror and the other is outside the mirror.

If the host wants to return to the Nine Realms, it needs to find a passage that can open this mirror. 】

"How can I get through?"

[The system doesn't know, the system is calculating, but it will take a long, long time to complete.]

The Heavenly Dao here is not compatible with the system, and even very unfriendly, the information that the system can obtain is very limited, and the host needs to explore and learn in person, or to be able to find a more powerful computing system, which can speed up the calculation of finding the exit channel.

Or, after the host breaks through the holy level and its own calculation ability is enhanced, it can calculate with the system. 】.

[In addition, the Terrans in this world seem to be very weak, and I hope that the host can help the Terrans, and if there is a Sage in the Terrans, you can invite him to do the calculations together.

Try not to invite Sages of other races, this world is dangerous and hostile. 】

"Isn't it dangerous?"

Han Yun muttered to himself.

This is the first time that the system has said that a certain world is dangerous, and it seems that you really need to be cautious here.

It's just that if you want to explore this universe, you need to see more.

After all, if he wanted to become a saint, it was impossible for him to meditate and cultivate on his knees, and then he would be able to break through.

Breaking through the sage has to rely on the rules of the universe to comprehend the breakthrough, if you don't even know the rules of this world, how can you break through?

It's just that if you want to explore the world, you have to restore your strength first.

It's a bit of self-preservation, isn't it?

Han Yun returned to the cave, and at some point, Qinglian had already changed her clothes, her underwear, her inner clothes and outer clothes, all dressed neatly, graceful and luxurious, and her whole body was full of the momentum of "I am the palace master of Wa Palace", which was not at all different from her previous charming and lazy appearance.

"How? Did you find anything?"

Qinglian stood up and asked.

"I came to the sky above to take a look, this world is different from ours, this is the galaxy universe, and it is different from our continent universe."

"What? What galaxy universe?"

"It's a planet, you know a planet?"

"I don't understand."

"Where's the stars?"

"I don't know, we don't have this word over there, a new word you invented?"

Qing Lianqiao's face was full of surprise.

"Uh...... How shall I tell you?"

Han Yun scratched his scalp and said,

"You always know what a ball is, right?"

"You know, the round ones are balls."

"Well, that's right, the earth under our feet is a ball, a ball floating in the universe, a planet, revolving around the sun, the sun is a star, understand?"

"I don't understand, how can the earth be a ball? Besides, how can such a big ball not fall down? How do you float in the air?"

"Because of gravity."

"What is gravity?"

Looking at Qinglian's curious baby's appearance, Han Yun was a big head.

Are you going to ask 100,000 why?

"This universe has countless planets, just like this one under our feet, many, many, many, every shining star you see outside is a star, and around each star, there are many planets like this planet under our feet......

"Okay, don't say it, I don't understand, you just say, how do we go back?"

"We...... I probably won't be able to go back for a while."

Han Yun said hesitantly.

"Can't go back? Can't even you do it?"

Qinglian was surprised.

Han Yun took out a mirror and explained the theory of mirroring the world to Qinglian, and Qinglian was stunned for a moment.

"Now, the world we live in is separated from the Nine Realms by such a mirror, and what we have to do is to explore the rules of the universe and find a way to pass through this invisible mirror and return to our world."

"Do you have a solution?"

"Not yet, maybe, when I am sanctified, there will be."
