Mu Xiaoyun continued, when the ability of a few human powerhouses reaches a certain level, they can achieve starry sky flight by themselves, and they can fly freely from one continent to another, whether it is to break through the space barrier or avoid various dangers in the starry sky, there is no problem.

But that's the real powerhouse!

In addition, there are two ways, one is the high-level Warcraft Flying Bird or Starry Sky Giant Bird, their volume is very large, the body reaches tens of meters, hundreds of meters or even thousands of meters, and the larger the body, the stronger the ability, first taming is a difficulty.

This kind of super existence, it is impossible to sign a master-servant contract with humans, they are the powerhouses of the starry sky, and humans will only help humans do things if they provide them with what they need.

Mu Xiaoyun and the people of their Spirit Pupil Gate took a hundred-meter-long giant bird to break through the space barrier of the Wuluo Realm, and the giant bird did not need to breathe in the starry sky for a short time, while Mu Xiaoyun and they only had to set up a space magic circle composed of yuan force on the giant bird's body, or a space cover, an independent small space.

In a small space, you also need some potted flowers and plants to provide breathing. During the whole flight process, the space cover is subject to various impacts and damage all the time, which requires special personnel to maintain it to avoid the space cover being destroyed.

Jiang Feng noticed that the source power of the magic circle required for the space cover mentioned by Mu Xiaoyun came from the Yuan Stone, because there was a large amount of Yuan Force stored in the Yuan Stone, which was even purer than the Yuan Power of the martial artist.

"Sister Yun, what is Yuanshi" Jiang Feng asked.

Mu Xiaoyun smiled indifferently, "Do you know that the spirit stone of the Dou Spirit Realm, the Yuan Stone and the Spirit Stone are the same, they are both the power of the Origin." ”

Jiang Feng shook his head, and he didn't know about the spirit stone.

However, regardless of whether it is a spirit stone or a yuan stone, Mu Xiaoyun is not willing to elaborate on this topic, so he will bring it over. What this woman said below is the point, the source power of the composition of the space circle is the Yuan Stone, and there is also an indispensable and important material, that is, the soul crystal!

There is also indescribable energy stored in the soul crystal, but the most important point is that the attributes of the soul crystal are special, and the space circle with the addition of the soul crystal, flying in the starry sky, can not only avoid some dark matter, but also release a certain breath, so that some creatures in the starry sky can smell the smell of the soul crystal and have a sense of fear.

There are several kinds of soul crystals, and what Jiang Feng displayed at the trade fair was a soul crystal with dark attributes, but the effect was the best one, which was bought by the old man of the Hua family at a high price of 600,000 gold baht, which fully reflected the value of the soul crystal.

And the reason why Mu Xiaoyun wanted to buy Jiang Feng's multiple soul crystals at one time was that in fact, when casting the space array, it was often attacked or destroyed, and the soul crystals needed to supplement and maintain the normal operation of the space array, just like the Yuan Stone.

It can be seen from this that the soul crystal plays an irreplaceable role in the starry sky flight, especially the soul crystal itself is formed by the soul core or crystal nucleus, which is hard to find, so it is basically a situation where there is no market for a price.

Mu Xiaoyun later said that in fact, the starry sky flight they had a few years ago was not intended to fly to the Dou Ling Realm, but due to the unimaginable trouble they encountered in the starry sky, they were forced to change their flight route in order to avoid the chaotic stone flow in the starry sky, and finally came to the vicinity of the Dou Ling Realm by mistake, because there were not many soul crystals left to maintain the space array, so they had to break through the space barrier of the Dou Ling Realm and fly to the Dou Ling Realm.

But since then, they have been looking for soul crystals and yuan stones to find ways to leave the Dou Spirit Realm, and in the past few years, they have found many spirit stones similar to Yuan Shi, but the soul crystals have no clue.

This time it was a coincidence, Jiang Feng had a soul crystal, and Mu Xiaoyun was of course overjoyed.

"Sister Yun, how many soul crystals do you need for a starry sky flight? Jiang Feng asked.

Mu Xiaoyun shook his head and said: "This is not true, because the starry sky cannot predict all kinds of troubles, if it goes well, one soul crystal for 180,000 li will do, but when trouble comes, a soul crystal will be needed for a thousand miles, otherwise, the space cover will be destroyed at any time." ”

Jiang Feng sighed lightly, he couldn't imagine that the thing he had happened to get at the beginning had now become a fragrant dumpling, a piece of 500,000 gold baht, which is really enough.

"Sister Yun, how many miles away is the Wuluo Realm from the Dou Ling Realm," Jiang Feng asked again.

"Almost 80,000 miles!"

Jiang Feng didn't continue to ask, is there at least one soul crystal at such a distance, and at most eighty If it is really as Mu Xiaoyun said, then the soul crystal is a good thing, and he is really a little reluctant to give Mu Xiaoyun so much.

Mu Xiaoyun seemed to see what Jiang Feng meant, smiled and said, "Good brother, are you a little embarrassed, let's throw away all kinds of unknown factors, in fact, there are five to ten soul crystals." Don't you want to tell me how many you have?"

It turned out to be ten pieces, so it didn't feel much pressure.

Jiang Feng grinned his teeth, "Hehe, Sister Yun, it would be fine if you said no, it would be fine if you said no, it is indeed difficult to have more, but ten or eight can still be made." ”

"That's really, that's great. Mu Xiaoyun's eyes lit up, and she almost had the urge to rush forward and kiss Jiang Feng fiercely, the little brother she just met was so cute!

Jiang Feng said: "Sister Yun, don't worry, I don't have so many on me, but I can guarantee that I can get ten soul crystals within three days!"

Although he recognized his sister and brother with Mu Xiaoyun, there were some things that could not be said, and Jiang Feng deliberately postponed it for three days for the sake of safety.

"Okay, as long as you can get ten coins, good brother, you have done a great deed, and our Spirit Pupil Gate will never treat you badly!" Mu Xiaoyun said excitedly: "I don't have so much money with me right now, I'll go to the Medicine Fragrance Pavilion to give it to you another day." ”

A big deal was negotiated.

In order to show sincerity, Mu Xiaoyun flipped his hand, and there was an extra pale cyan jade plaque in his hand, the size of his palm, and the surface was smooth and round, which looked like a high-grade jade.

Mu Xiaoyun handed the jade plate to Jiang Feng and said, "Good brother, I'll treat you first, this is one of the secrets of our Spirit Pupil Sect, you must cultivate hard, it will definitely be good for you." ”

Cheats Jiang Feng was stunned when he took the jade card in his hand, and he didn't know what to do with the jade card.

Mu Xiaoyun smiled indifferently, "Good brother, you don't know how to use this spirit jade, right, this spirit jade has memory attributes, you can copy words and images in it, you just need to put your forehead on the jade plate, calm down, and you can see the words inside!"

Lingyu, memory Shi Jiangfeng According to what Mu Xiaoyun said, he gently pasted the jade plate on his forehead, eliminating all selfish distractions, and sure enough, when the jade plate touched Jiang Feng's forehead, streams of information poured into his sea of consciousness.

It's so wonderful that the transmission of this memory stone can be directly imprinted into the sea of consciousness, eliminating many links.
