The advantage is that the cultivation of Yun Rougang's Qi Realm is almost invincible in the ground, and it can indeed protect Yun Tian. But the downside is that if you meet a super powerful demon powerhouse, maybe the two of them won't even be able to escape.

Although this kind of super demon powerhouse is difficult to meet underground, there is also this possibility, so behind every benefit, there is a disadvantage.

"Rou'er, the underground is very dangerous, you still don't want to go, just practice hard in Yunyang Peak, wait for me to come back, next time I go out to practice, I must take you with me, how about it." Before Liu Yun could speak, Yun Tian spoke, he had been underground before, and he naturally knew how dangerous it was.

"No, big brother, I can't live without you!" Yun Rou pouted and said reluctantly, although she knew that Yun Tian was for her own good, she still wanted to accompany Yun Tian.

Yun Tian shrugged his shoulders helplessly, looking at Liu Yun, whether to go or not was ultimately up to Liu Yun to decide, after all, Liu Yun had more experience than him.

"In this way, although Rou'er is a cultivator at the peak of the Gang Qi Realm, she also lacks actual combat experience, so let her go this time. Liu Yun said, not to mention how happy Yun Rou was, "However, you are not allowed to go deep underground, lest you encounter accidents." ”

Seeing that Liu Yun promised to go underground, Yun Rou smiled and quickly nodded in agreement, for fear that Liu Yun would suddenly change his mind.

"It's okay, remember my mother's teachings, I won't go deep underground!" Yun Tian nodded.

"Mmmm, I won't go, I won't go, so when are we leaving?" Yun Rou was obviously very excited, and hurriedly asked.

After pondering for a moment, Yun Tian said: "We will leave early tomorrow morning, go early and return early, so as not to delay on the road." ”

"Good!"

...........

Before dawn the next day, Yun Rou ran to Yun Tian's room, but found that Yun Tian was not in the room, and she was puzzled for a while, and when she walked out of the Tianyun Palace, she saw a scene that made her even more confused.

On the square of the Tianyun Palace, there stood a crane two or three people tall, with wide wings like a giant door panel, rich and handsome, and the crane top of this crane was red like a jumping flame.

The crane roared a long way, earth-shattering, a flap of its wings, enough to blow people away, such a big crane is not an ordinary crane, but a kind of alien species, a fly down, even leopards, rhinoceros, tigers and other beasts, can be caught alive.

There is only a super faction like the Four Great Immortal Sects that has this kind of crane.

Suddenly, Yun Tian appeared next to Yun Rou, looked at the huge crane and said, "I have to go to the crack of the underground world to pass through a dynasty, countless large provinces, I found a crane in the crane courtyard, so that I can quickly reach the underground world, although we have a treasure, but the goal is too big, far from being as easy to use as the crane." ”

After Yun Tianyi's explanation, Yun Rou understood that although the treasure weapon is good, it will definitely arouse the ideas of others when flying, if you encounter a murder and treasure grabbing, the gain will outweigh the loss, and the crane will not have so many scruples, who dares to rob the crane of the Immortal Dao sect?

In the True Yuan Sect, the True Sect disciple was given a mountain peak, and he was able to raise spirit beasts, which can be said to be a small sect within the sect.

A true disciple is a disciple who can start a sect and establish a sect, and can cultivate talents by himself, and his strength in the sect is unimaginably great.

Only when you become a true disciple of the True Inheritance can you be a true disciple of the True Yuan Sect and be able to participate in the decisions of the upper echelons.

And Liu Yun is a true disciple, so naturally he also raised some immortal cranes in captivity, which usually have no effect, and now they are just used to replace the foot journey.

"Big brother, shall we leave now?" Seeing that everything was ready, Yun Rou asked, both of them had the space container space treasure bag given by Liu Yun, and the things they needed for daily use were all in the space treasure bag, and now they were traveling lightly, which was countless times easier than other disciples.

The space treasure bag is refined with a material called the Void Crystal Celestial Stone, and there is a certain space in it, which can be regarded as a magic weapon that has become a void by itself, and has no other function, it can only be used to store items.

With such a thing as a space treasure bag, I am not afraid of the trouble of carrying items when I go outside to collect medicine or practice, and I save a lot of things. However, the space treasure bag is also very rare, and even some of the inner disciples of the Gang Qi Realm of the True Yuan Sect do not have them, let alone other disciples.

It can be seen how precious and rare the space treasure bag is.

"Well, let's go!" Yun Tian nodded, as soon as his body moved, he turned on the crane's back, Yun Rou smiled, and sat in front of Yun Tian, and then the crane instigated its huge wings and slowly flew towards the sky.

Yun Tian only felt a shock all over his body, and only saw the mountains and forests below, the peaks, dotted around, and the palace was only the size of a fist.

Yuntian and the two didn't dare to be careless, buried their heads, the whole person didn't enter the crane feathers, as if wearing a huge crane feather, the air flow glided over the feathers, and the whole person suddenly relaxed a lot.

When Yun Tian and the others just left, Liu Yun appeared in the square, looked at the direction of Yun Tian and the others left, smiled slightly, and then disappeared.

The crane flies very fast in the sky, and the mountains are left behind, but every five or six hours, the cloud sky will descend and rest for a while, after all, the crane is also flesh and blood, and it is very difficult to fly for a long time, and it needs to rest and drink water to replenish its strength.

Half an hour later, Yun Tian and the others flew to a dynasty that did not completely belong to the jurisdiction of the True Yuan Gate, the Taishang Dynasty.

Because in addition to the Zhenyuan Sect recruiting disciples in the Taishang Dynasty, there are also some other immortal sects that also recruit disciples in the Taishang Dynasty, such as the Tianxing Sect.

"Although I have gone to many ancient extinctions, I have not traveled to the Taishang Dynasty, and I can't imagine that the world is so magnificent and beautiful?"

Above the sky, a white crane flies below the clouds, the mountains and rivers below are picturesque, the cities are vast, the crowd is like ants, the cities, the roads, the traffic, the prosperity of the world, and the red dust are all in the eyes.

Admired from high in the sky, Yuntian was full of emotion.

However, Yuntian also knew that the Taishang Dynasty was not the most prosperous country, and there were several major dynasties to the east, especially the Pure Light Empire under the command of the Huashen Palace, with a population of more than 10 billion, covering an area of 84,000 states.

In comparison, the Taishang Dynasty is nothing at all, but Yun Tian doesn't care, he came here to practice, not to investigate Feng Shui human feelings.

After the crane flew in the sky for a day and a night, the two of them finally arrived at the border of the Taishang Dynasty, and at this moment, a huge abyssal crack suddenly appeared on the endless plain.

The crack in the abyss seemed to split the whole earth, and the crack was dark inside, I don't know how deep, and occasionally the shadow of a bat flew in it, adding a touch of mystery.

"I have gone down to this crack, and in the depths of the crack, there are many mineral veins, among which there are heavenly law yuan stones containing mana, as well as all kinds of medicinal materials, etc., which are heavily guarded and mined by the army of demons underground. Yun Tian pointed to the huge crack in the ground in front of him and said to Yun Rou.

Tianfa Yuan Stone is a very mysterious spirit stone, because it contains the Yuan Power of the Law! It is very rare, it is rumored that it is a kind of spirit stone formed by the combination of residual spiritual energy and jade in the primeval era, the Great War of Immortals and Demons, the Ancient Demon God, and the immortals turned the world upside down with huge mana.

Mana is generally only available to the masters of Jindan, but this kind of stone has it, which can refine all kinds of magic weapons, and even assist people's spiritual cultivation, and can also improve the quality of the pill.
