At the teleportation point, Lu Yanning used the teleportation array to teleport directly to the door of Wu Fei's hotel room.

In fact, before that, Lu Yanning had guessed that the fact that the cave world could be teleported to any place within the range of Wudang Mountain should not only be a specific reason for the cave world itself, but should contain some strategic reasons. For example, if a foreign enemy invades, then you can teleport from the cave world to any place in the outside world, which is very advantageous whether it is offensive or defensive.

Moreover, Lu Yanning also suspected that if it was really in wartime, he was afraid that there would be many more teleportation points in the Cave Entrance Heavenly World, and he did not need to enter and exit from the fixed teleportation point that he was entering and exiting now. It's just that his current level is not enough, so he can't know these secrets yet.

Of course, it's just speculation.

Entering the room, Wu Fei poured Lu Yanning a cup of tea, and asked some questions about what he learned yesterday, and Lu Yanning answered them one by one, he had already cultivated this part of the content, so it was naturally easy to solve.

Lu Yanning planned to finish the cultivation content of the Jade Appreciation Technique to Wu Fei within a few days, and then let her go back first. He still has to cultivate himself, it has been less than a month since he went to the Tianshan Mountains to explore the small secret realm, although it is impossible for him to break through to the Tongxuan realm in such a short period of time, but there are other cultivation contents, such as iron wire vine.

Grinding guns in battle, not fast and light!

In the next few days, Lu Yanning came out in the morning to instruct Wu Fei to cultivate, and in the afternoon, he went back to the Cave Heaven World to cultivate by himself.

As for why he didn't practice with Wu Fei on the mountain, it was naturally because the aura of the outside world was not as rich as the Cave Heaven World, and in the Cave Heaven World, his practice room still had a Spirit Gathering Array to use.

"Okay, I've pretty much talked about what I should tell you these days, and it's not a good idea for you to stay in the hotel all the time, so let's go back to school. Lu Yanning said to Wu Fei.

Wu Fei was stunned, "But I haven't been to the Cave Heaven World yet, and I haven't gone to meet my ancestor yet!"

Lu Yanning shook his head, "I can't help this, anyway, I can't bring people in, I have to rely on you to cultivate the jade jian yourself, and then use the method I taught you before to get in." As for your ancestor, let's wait until you can enter the cave world, and your ancestor is not here now, he has gone to Tianshan. ”

"Tianshan, isn't Sister Ling in Tianshan? And I remember Master, you said that you are going too, take me with you, anyway, I have nothing to do when I go back to school, and the class is over." Wu Fei shook Lu Yanning's arm, with a "please" expression on her face, not to mention that it was really a little cute.

However, Lu Yanning will not be deceived by this expression, this cheap apprentice of his own family is really not so cute, it is pretended!

"What are you going to do, I just went because I had something to do, the Tianshan Mountains are so far away, and it's still cold!" Lu Yanning pouted, "It's not fun over there, so you better go back to school." “

Without waiting for Wu Fei to say anything, Lu Yanning directly teleported back to the Cave Heaven World and went straight to the Tongwei Palace.

Originally, it was said that it would be possible to solve the secrets in "Empty Hands" in two or three days, but in fact, it took five days to get it done, and today is the sixth day, so Lu Yanning plans to take a look.

"Little junior brother, you came just in time, I was about to ask someone to find you. Zhao Xuanji smiled and said, "Your second senior brother and I have completely unlocked the secret of the inheritance of the empty gate. ”

Lu Yanning was also very happy, "Congratulations, senior brother!"

The second senior brother on the side, Ou Xuanxi, yawned and said, "I've been tired these days, I'll sleep first, don't pay attention to me." After saying that, he ran directly to the side and lay down to sleep.

Zhao Xuanji said to Lu Yanning, "Your second senior brother and I have been sleepless for the past few days, and we have finally solved the secret. ”

Lu Yanning poured a cup of tea and served it, "Senior brother, why don't you go and rest, just go back and tell me about it." ”

Zhao Xuanji took the tea, took a sip, and said, "It's okay." Aren't you going to the Tianshan Mountains, as long as you get started with this inheritance, it will be of great help to you on this trip. ”

After speaking, he handed over a booklet, "This is the complete content that your second senior brother and I have sorted out, you can take a look." I'll meditate and recover first, and then ask me any questions. ”

"Okay, senior brother, go and meditate. Lu Yanning took the booklet, walked to the side and read it by himself.

The content in the booklet, the beginning part is okay, relatively straightforward, I think it was translated directly by the two senior brothers. And the part that involves the principles and techniques of the exercises is particularly obscure, obviously I know every word in a sentence, but what to say together is completely confusing.

Lu Yanning wondered if he had taken it wrong.

However, it is clear that this cannot be a mistake.

Turning his head to look at the second senior brother sleeping on the side and the senior brother who was meditating, Lu Yanning didn't bother the two senior brothers. He ignored the last part of the booklet for a moment, and carefully began to read the first part word by word.

Through the "Preface" or "Preface" part in front of this, Lu Yanning figured out that the original cultivation of the Empty Gate was an energy called "Empty Power", which was referred to as "Empty Power". This air power, which is different from true qi and spiritual power, is a very mysterious energy that involves the cultivation and use of space.

Lu Yanning secretly exclaimed, the person who passed down the Empty Gate Inheritance was definitely a bull, a real boss! The most common technique involving space used in the cultivation world was storage equipment, and even bigger, it was the Cave Heaven World and the Secret Realm and the like.

Storage equipment, in fact, involves the use of space is really not too much, more of the use of the principle and method of the formation.

However, the cultivation of this kind of empty power inherited from the Empty Gate is directly cultivated on the cultivator's body, so that he can use the many characteristics of space to do many things.

From the level of the realm, it has already involved things at the level of the law.

The cultivation of the power of emptiness, the sign of entry is that you can open a void space around you, or form a special space, this space moves with the movement of the cultivator himself, a bit like storage equipment, but it does not need a carrier. This space cannot be seen or touched by others, let alone opened, and only the cultivator himself can see, open, and use this space.

Well, it's an invisible mobile safe!

And with the improvement of cultivation, it is even possible to hide itself in the void, which is difficult to explain clearly. In other words, it is clear that the person is there, but others cannot see or touch his existence or sense his existence, as if he is in a different time and space. Of course, only space is involved, not time.

However, it is almost impossible to cultivate this kind of air power on your own. This requires a considerable comprehension and understanding of the laws of space, and for ordinary cultivators, the laws of space are out of reach!
