"Are you talking about the aura of heaven and earth?" asked Yinyue, still a little confused, obviously she didn't know what the atmosphere was.

"Ahem, you can also understand it that way, just think of it as the aura of heaven and earth. Li Muyun touched his nose helplessly, and then continued: "The aura of heaven and earth on Qingyu Star is relatively abundant, leaving Qingyu Star and entering the starry sky, the aura of heaven and earth will not be so rich, so it can be said that the atmosphere is the layer of heaven and earth aura that wraps Qingyu Star." ”

"So you mean to say that we will rush out of Qingyu Star directly, fly in the starry sky, and then go to other planets?" Yinyue looked at Li Muyun with an expression of "Did I hear it wrong" and asked him.

"Eh, isn't this way possible? Then how do we leave Qingyuxing? I have never left, how did you leave Qingyuxing before?" Li Muyun was a little embarrassed, but still asked shamelessly.

"It's not that you can't do it, but there are very few cultivators who will fly away from the planet and fly to their destination on their own in the starry sky, unless you have a special flying apparatus or have a powerful means of flying, otherwise, flying to the starry sky with the normal flight on the planet will definitely exhaust you to death. Yinyue explained.

"This is true, the space outside the starry sky is too vast, the planet only occupies a very small area of the entire True Mortal Realm, and the empty starry sky is the largest area, if the starry sky is compared to the stage, then the planet is just a grain of dust on the stage. Li Muyun also admitted that what Yinyue said was very reasonable, and nodded and said.

"So, if a normal cultivator wants to cross the star field, from one planet to another, or from one galaxy to another, they all use a teleportation array. Yinyue said with a slight smile.

"Teleportation Array?" Li Muyun was surprised when he heard this, "Isn't the Teleportation Array only used on one planet, can it still be transmitted from one planet to another?"

"Of course you can, you're so lacking in trying!"

Yinyue couldn't help but sigh: "The teleportation array is also divided into several types, the teleportation array in the planet you said is the most basic and basic teleportation array, this kind of teleportation array is relatively simple, and the spirit stones consumed are also very few, but the teleportation distance is also relatively short, it is just a teleportation within the scope of a planet."

One level higher than the teleportation array in the planet, it is the interstellar teleportation array, that is, the teleportation array that is teleported between planets and galaxies, this teleportation array is undoubtedly very powerful, but the consumption is also relatively high, and it is not as easy to build as the teleportation array in the planet, so it is not as much as the teleportation array in the planet.

The most powerful teleportation array should be the 'Nebula Array', which is a very powerful teleportation array, which can be teleported from one plane to another.

If it is a plane world like the Immortal Buddha and Demon, you can't use the teleportation array to teleport, you can only use the plane channel, and how difficult the plane channel is to open up, I think you also know it, right? Therefore, the cross-space nebula circle is only teleported in the True Mortal Realm and the world where the plane energy level is lower than the True Mortal Realm. ”

"Cross-Space Nebula Array?Plane Energy Level?" Li Muyun was a little confused when he heard these terms that he had never heard before, and he didn't know what Yinyue was talking about at all.

"There are many dimensional worlds where mortals exist, but most of these worlds have very few human beings, only the true mortal realm has the largest number of human beings in this dimensional world, and the rest are like some dimensional worlds with human existence, and some of the entire dimensional worlds only have human beings on a few planets, such a dimensional world will generally become a trial planet controlled by the Immortal Cultivation Sect. ”

Yinyue saw the confused look on Li Muyun's face, and immediately explained, "And the reason why the number of mortals in the plane world of the True Mortal Realm is the largest, and the number of humans in the rest of the plane worlds is relatively small, the most critical reason is the plane energy level. The so-called plane energy level is the level of the entire plane world, which is determined by the strength of the basic performance energy in the entire plane world. ”

"Basic energy? What is that?" Li Muyun was at a loss when he heard this, he found that he hadn't understood a term yet, but another term came to him, which made him feel that his understanding of this Xianxia world was still very superficial, and he couldn't help but sigh that there was really no systematic cultivation from scratch, but he knew more than the cultivators who had systematically cultivated from scratch for hundreds of years.

"You listen to me explain slowly, who knows that you actually know so little about many common sense issues in cultivation, don't you Yunlan Sect teach these? These common senses are not very profound, basically even if it is a casual cultivation like me, you will understand it!" Yin Yue was a little speechless and put her hand on her forehead and said to Li Muyun.

"Alright then, you explain slowly, I'll listen. When Li Muyun heard this, he quickly covered his mouth, saying that he would not interject casually.

"Let's start with basic energy. ”

Silver Moon nodded, and then slowly explained, "Each plane world has its own basic energy, and different plane worlds may be the same basic energy, and worlds with the same basic energy can generally be regarded as the same world.

For example, the basic energy of the true mortal world is the ubiquitous aura of heaven and earth, and the basic energy of the fairy realm is the qi of the fairy spirit, the basic energy of the demon realm is the qi of the demon spirit, the basic energy of the Buddha realm is the qi of the Buddha spirit, and the basic energy of the demon world is the qi of the demon spirit.

It is said that the basic energy of the Divine Realm is called the Qi of the Divine Yuan, but I just heard that unlike the basic energy of the Four Realms of Immortals, Buddhas and Demons, it is almost no secret in the True Mortal Realm, as long as you inquire casually, you can know, because the power of the Four Realms of Immortals, Buddhas and Demons, some of them can be in the lower realm, and they can be supreme elders in the cultivation sects in the true mortal realm, so we can know some information about the upper realm. ”

"Then in this way, the plane energy level you are talking about should be related to the basic energy in the plane world, right? Is it true that the higher the plane energy level, the more powerful the basic energy?" Li Muyun suddenly interjected when he heard this.

"You're smart and you guessed exactly right. ”

Yinyue said approvingly to Li Muyun, "You're right, the strength of the basic performance energy of the plane world determines the level of the plane energy level, for example, compared to the True Mortal Realm and the Immortal Realm, the aura of heaven and earth is obviously inferior to the qi of the immortal spirit, so the plane energy level of the True Mortal Realm is not as good as the immortal realm."

The higher the plane energy level of a plane world, the more stable the plane world is, and the more it can withstand the ravages of stronger forces. It also marks the prosperity of the dimensional world. ”

"Can withstand the ravages of stronger forces? Li Muyun's brows furrowed slightly, and he asked Yinyue for advice.

"Let's take an analogy, in this True Mortal Realm, the strongest power that can withstand is just the strength of Da Luo Jin Xian's full blow, beyond this power, the entire True Mortal Realm may collapse.

Therefore, although there are people in the immortal realm, they are generally immortals in the realm of Da Luo Jin Immortal or below Da Luo Jin Immortal, and there are very few immortals above Da Luo Jin Immortal in the lower realm, just because they are worried that the true mortal realm will not be able to withstand the impact of too strong forces. ”

Yinyue continued to explain, "There are also some dimensional worlds, which are lower than the dimensional energy level of the True Mortal Realm, it is estimated that the cultivators of the God Realm enter such a dimensional world, as long as they strike with all their strength, that dimensional world may be destroyed, this is what the dimensional energy level can represent, what kind of power can withstand the wrath of the rage." ”

"Is there such a fragile world? A cultivator of the God Realm can destroy a world with a single blow with all his might? This is too ...... It's incredible, isn't it?!" Li Muyun was a little stupid when he heard this, and felt that what Yinyue said was a bit subverting his concept.

"The world that a Divine Realm cultivator can collapse with a single blow is actually quite strong, and the most terrifying thing is that there are many dimensional worlds, and some dimensional worlds are so fragile that cultivators in the Qi Realm and Dan Realm can easily destroy them, but it is difficult for cultivators in the Dan Realm and Qi Realm to enter that kind of world by themselves. Yinyue explained.

"That'...... Those fragile worlds, what's the point of their existence, if that world develops civilization and human beings, wouldn't it be on the verge of destruction at any time? This is also terrifying, isn't it?" Li Muyun couldn't help but smack his tongue and said, it was hard for him to believe that a world would actually be destroyed under the full force of a Qi Realm and Dan Realm cultivator.

"Every world has its purpose. ”

Yinyue explained, "Just like us cultivators look at mortals, those mortals have been mediocre all their lives, just a hundred years, their lives are so short, so fragile, birth, old age, sickness and death, if there is a little natural or man-made disaster, it is possible to die. Does it make sense to us cultivators?"

"Well, what you said makes sense, I'm just ...... I'm just a little surprised, there are still such fragile worlds, fortunately, it is difficult for us cultivators to enter those worlds, otherwise, it is estimated that those worlds will be even more fragile. ”

"Actually, it's not difficult to say, the cross-space nebula magic circle can allow cultivators to enter those worlds. ”

Yin Yue said again, "As long as the plane energy level is in the plane world below the True Mortal Realm and the True Mortal Realm, a cross-space nebula magic circle can be established, and as long as there is this kind of teleportation circle at that time, those fragile plane worlds can also be entered by cultivators at will." ”
