Achievement system: I am cultivating immortals in the world of martial arts

He wanted to explore this world, but he was worried that the powerful people in this world would be hostile to him, so it was better to be cautious.

At this moment, he was just like the one he was when he first traveled to the martial arts world.

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

"System, what kind of world is this? Is it a different universe?"

[This is the main universe, not a different universe. 】

"Main universe? I traveled through time again? How could it be the main universe? Are we in another big universe? Is it the world of Emperor Xi and Wa?"

[No, this is the negative plane, the negative plane of the nine realms. 】

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

[Received, everything in the world has two sides, Yin and Yang. Where there is Yin, there is Yang, where there is Yang, there is Yin, and where there is a positive plane, there is a negative plane.

For example, the world that Xihuang and Wahuang are in is the positive plane they are in. This is how they call their universe.

Their positive plane includes the endless universe, the origin plane, the high spiritual plane, the middle spiritual plane, etc., while the plane opposite them is called the negative plane.

The races in the negative plane are completely different from the positive plane. The special race there is called the demon race, also called the negative plane demon race! 】

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

[Yes, those demons come from the negative plane of Xihuang Universe.

And where we are now is the negative plane of the Nine Realms, which is on the opposite side of different time and space from the Nine Realms.

This is different from the Nine Realms. The Nine Realms are the continental world, and this is the Galaxy World. There are various civilizations in this world. Their cultivation systems are completely different from those of the main plane. The host needs to see the specific situation in person.

There are also local demons in this world, but unlike the demons that invaded the Wuling Realm, the demons there are demons from the Xihuang Plane, not the Nine Realms Negative Plane, 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 practice. Now I just want to know, how should I go back?"

[The system does not know because the system cannot sense the orientation of the Nine Realms and does not know where the Nine Realms are. The system only has information on the positive and negative planes of the Xihuang Universe.

Over there, the positive and negative planes are separated by the sea of ​​suffering, which is the end point of all abandoned universes.

However, the rules of the Nine Realms and this galaxy universe are completely different from those in Xihuang's world, and there is no sea of ​​suffering. Therefore, the system does not have any information about this galaxy universe, and the system needs to continue learning and trying calculations to know.

What is certain is that this is not a different universe. The different universe relies on the Nine Realms. You only need to find the 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, he needs to find a passage through 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 calculation.

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

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

[In addition, the human race in this world seems to be very weak. I hope the host can help the human race. If a saint can appear in the human race, he can be invited to do the calculation together.

Try not to invite saints from other races. This world is very dangerous and very hostile. 】

"Is it dangerous?"

Han Yun murmured to himself.

This is the first time that the system has said that a certain world is dangerous. It seems that we really need to be careful here.

However, to explore this universe, you need to see more.

After all, if he wants to become a saint, it is impossible for him to sit cross-legged and meditate and then achieve a breakthrough.

A breakthrough saint must rely on the rules of the universe to understand the breakthrough. If you don't even know the rules of this world, how can you make a breakthrough?

But if you want to explore the world, you must first restore your strength.

You have to have some ability to protect yourself, right?

Han Yun returned to the cave. At some point, Qinglian had changed her clothes. She had changed all her underwear, middle and outer clothes. She was neatly dressed, graceful and luxurious, with the aura of "I am the Lord of the Wa Palace" all over her body. , completely different from the charming and lazy appearance before.

"How's it going? Did you find anything?"

Qinglian stood up and asked.

"I went up to the sky and took a look. This world is different from ours. This is the galaxy universe, which is different from our round sky, earth, and continent universe."

"What? What galaxy universe?"

"It's the planet, do you understand the planet?"

"don't know."

"Where are the stars?"

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

Qinglian's pretty face was full of surprise.

"Um...what should I tell you?"

Han Yun scratched his scalp and said,

"You know what a ball is, right?"

"I know, the round ones are balls."

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

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

"Because of the existence of gravity."

"What is gravity again?"

Looking at Qinglian's curious baby look, Han Yun felt dizzy.

Are you going to ask a hundred thousand whys?

"There are countless planets in this universe, just like the one under our feet. There are many, many. Every shining star you see outside is a star, and around each star, there are There are many planets like this one beneath our feet..."

"Okay, stop talking, I don't understand, just tell me directly, how should we go back?"

"We...may not be able to go back for a while."

Han Yun said hesitantly.

"Can't go back? Is there nothing you can do?"

Qinglian said in surprise.

Han Yun took out a mirror and explained the theory of the mirror world to Qinglian, which made Qinglian stunned.

"Now, there is only such a mirror between the world we live in and the Nine Realms. 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."

"Then can you do it?"

"Not yet. Maybe, when I become a saint, there will be."
