Qian Qian sighed lightly: "I originally thought that I still had some talent, but as soon as I entered the rivers and lakes, I encountered all demons, and I didn't know if it was luck or misfortune." ”

After that, he rarely stopped talking.

Yan Yue was also silent for a long time.

In mid-air, the majestic and wanton true qi around Xinghao began to gradually subside, and Xinghao's figure stretched slightly, landing in front of everyone, nodding slightly.

is also a true Yuan realm, Xiao Yin felt that Xing Hao's body was not weaker than his own breath, and he was also secretly amazed.

Xiao Yin knew that his Qi Mansion was transformed by the remnant soul of the powerful secluded gauntlet of the ancient heavenly and human realms, and the true yuan that was born here was by no means ordinary, coupled with his own unremitting cultivation of the Heaven Killing Sword Technique day and night, the purity of his own true yuan far surpassed that of his peers, and the reason why he dared to cross the border to challenge Xu Fengyan today was naturally forced by the situation, on the other hand, Xiao Yin also wanted to use the high realm cultivators to try the results of his recent cultivation. Although it is naturally impossible to defeat the opponent, Xiao Yin is already very satisfied with being able to retreat with his whole body, and he also has a clearer understanding of the general level of his cultivation.

But now facing the star haze who had just entered the realm of True Yuan, Xiao Yin felt a trace of coercion. This was only when facing the True Crystal Realm master, Xiao Yin would have a similar feeling. Thinking of the experience when he first met Xinghao, he found that Xinghao could defeat the opponent of the True Yuan Realm with the strength of the True Qi Realm, Xiao Yin couldn't help but be secretly frightened. Xiao Yin was even thinking that if he encountered Xu Fengyan again at this moment, he and Xing Hao might join forces, and maybe there would be another result.

In Xiao Yin's eyes, the star haze in front of him was like a sharp sword that could be forged, although it had been retracted into the sheath, it could not hide the shocking edge.

The sword mound walks in the world, and it is amazing.

The sword mound behind it is only more mysterious......

I don't know if there will be a chance to have this sword mound in the future......

However, as soon as he thought of his situation, Xiao Yin didn't continue to think about it.

Xiao Yin said: "The stargazing girl entered the country tonight, and her strength has increased greatly, which is a good thing for everyone, and she has more self-protection power to go to the ghost domain." Alright, let's go rest again. ”

And they departed as they were told, and rested to their own men.

The next day, under the leadership of Youlan, the people did not enter the city, but walked along a deserted path on the outskirts of the city for half a day, and then passed through several misty hidden valleys and several dangerous places, and finally came to the end of a deep canyon.

An ancient bronze gate about three feet high is embedded in the mountain wall at the end of the canyon.

This bronze ancient door is divided into two left and right doors, which are closed at the moment, and the two ancient doors are carved with symmetrical mysterious lines, surprisingly, there are wisps of strange red gas flowing back and forth according to a certain law on the lines, adding a trace of mystery to the entire bronze ancient door.

Qian Qian stared at the red gas, stared for a moment, and suddenly lost his voice: "Could it be that this is the legendary leyline aura?"

Youlan nodded, "Not bad." This is the legendary aura that can open up the earth's lungs and form the earth's lung channel. ”

Qian Qian shook his head and marveled for a moment, then looked at the rest of the people: "The so-called leyline aura, I heard that it is a special gas born from the core of the earth's lungs thousands of miles underground. This gas has a miraculous effect, that is, you can drill through any hard core boulder, thus opening up a unique channel of the earth's lungs. And once this kind of earth-lung channel is formed, it can break through the spatial barrier and achieve a miracle effect similar to space shuttle!"

"Space shuttle?!"

Everyone's eyes widened.

Qianqian nodded and said, "Yes." I heard that in ancient times, there were sages and sages in the realm of heaven and man who could teleport thousands of miles in an instant. However, this kind of speed is by no means achievable by human beings, and even if it touches the supreme power of the realm of heaven and man, it cannot violate the natural laws of the world. Therefore, some people speculate that it may be this sage who has used this kind of earth-lung passage to move space. ”

"There is such a thing in the world?!It can't be a rumor, right?!"

Qin Mei's eyes widened on the spot.

Qianqian said: "I also saw it from an ancient anecdote in Tianji Pavilion, whether it is true or not, I don't know." However, from the outside, the red gas on the ancient gate in front of us is very similar to what is described in the book. ”

Xiao Yin, who had been silent, suddenly spoke: "It's true." ”

Everyone was stunned.

Xiao Yin said: "I have read a classic written by an ancient sage, and it mentions the leyline aura, which is roughly the same as what Qian Qian said. Moreover, space shuttle is also real, but in an instant, teleportation is exaggerated. In most cases, a space shuttle can reach a distance of 100 miles. Because outside the earth's lung channel, there is an endless earth's core lung vein, during which there are often all kinds of earth-lung poisonous fire, miasma, poisonous smoke, and even abyssal strange insects and other strange and treacherous things, ordinary people can not stay in the channel for a long time, otherwise it is very easy to suffer from these poisons. Moreover, the space shuttle in the underground will form an extremely terrifying space pressure, even if the cultivation is profound, it cannot be deep in it for a long time, otherwise even if the body can resist this space pressure, the internal organs in the body will not be able to withstand this huge pressure and suffer heavy damage. ”

Qianqian's eyes lit up and he said, "Which book did you see it in?"

Xiao Yin blinked and said, "I won't tell you." ”

Humility: "......"

Xiao Yin ignored Qianqian, but looked at Youlan and asked, "No wonder this ghost domain is so mysterious and unpredictable, it turns out that the entrance is a leyline channel formed by the leyline aura. Moreover, if I guessed correctly, there should be more than one entrance to the ghost domain, there should be many?"

Youlan praised in surprise: "Childe is really extraordinary! Not bad at all, this entrance is only one of the many ghost domain entrances, it is the special entrance of my Tianqi Guard, and the rest of the forces don't know about it." Of course, the entrance to the ghost domain of the rest of the forces, Tianqiwei did not know. After all, this kind of critical place is top secret for any force. I think the reason why I knew about the ghost domain in the first place was also by chance, because I had to complete a special task, so I was brought here by the Gongsun Commander. When I first saw this door, I was just like everyone else, I was shocked, even after the Gongsun Commander explained it to me, I couldn't believe it, until I stepped through this door, I really believed that there was really space to shuttle in this world!"

Xiao Yin said: "Therefore, through this door, it is the leyline channel, and only through the leyline channel can you reach the ghost domain by shuttling through the space." ”

Youlan nodded, "Yes." ”

When everyone heard this, they couldn't help but show a trace of nervousness, but they were extremely excited.

Space Shuttle!

This thing, which only existed in the rumored myths, suddenly appeared in front of them at this time!

"Sister, can we really go through? How far is it? How long will it take? Will I get dizzy?"

Like a little sparrow, Qin Mei immediately chirped a series of questions.

Youlan said: "I don't know how far it is, because in the leyline channel, people's eyesight can't keep up with the speed of space shuttle, and it is impossible to estimate the distance at all." At that time, I only had a rough estimate of the time in private, and from the beginning to the end, it should only be the time for a stick of incense. The whole process will not cause any discomfort to the human body, but the five senses of the human body will temporarily fail, which everyone should pay attention to and do not panic. ”

Xiao Yin said: "It's not been long, so it seems that this entrance should be very close to the Ghost Domain." I don't know, where does this lead to the ghost realm?"

Youlan said: "Tianqiwei top-secret town, Qingyun Academy." ”
