When he saw the big net appear, Li Nan was immediately attracted to it.

The reason is simple, he was able to understand.

On this invisible energy net, his divine sense swept over it, and soon found that there were many dense runes on it.

Science divides matter into many elements, particles.

But metaphysics summarizes all the rules into runes.

When a set of runes is strung together, it will become a powerful formation, and as long as it is triggered, it can burst out with great power.

In the eyes of metaphysics, everything in the world is composed of various runes, but the runes that humans can use are limited, once they master all the runes and create people out of thin air, they can be realized, and then they will become the creator of the whole world.

The Immortal Immortal Sutra is very powerful, but in other aspects, there are almost no exercises that can be compared.

Alchemy, refining, can be a perfect match.

Even the formation can be learned very quickly.

The formations here are obviously not particularly advanced, and those runes are composed of simple and easy to learn.

Remember http://m for a second.

But if no one teaches them, they won't be able to learn those runes at all. With just one formation, even if it is a lu civet, it can't see what runes are made up of inside.

Li Nan was different, he had cultivated the Immortal Immortal Sutra, and just by looking at it with his divine sense, he could immediately parse out all the runes.

Of course, it will definitely take a while to master all the runes, but he has already figured out the principle of the entire formation.

This is a bloodline forbidden array!

If you want to open it, you must have two people with the same bloodline, and you must combine inside and outside, and input mana at the same time.

If it is broken by force, it will require several grandmasters to work together in the third step and use powerful mana to directly destroy the operation function of the formation.

But it only lasts for a while.

And then ......

There is no more, if you want to come out of it, in addition to using the characteristics of the bloodline forbidden array, it is much more difficult to forcibly break the formation than outside.

But in Li Nan's opinion, his mana should be able to directly break through the formation, whether it is from the inside or from the outside.

There is no need for others to cooperate, as long as he finds the right runes connected inside and outside, and inputs the mana into it, the large array can be automatically opened.

This is the function of the Immortal Immortal Sutra, the mana cultivated can perfectly fit anything, and it can also be converted into the required attributes at any time.

The method of Dragon Guarding Villa, in Li Nan's opinion, did not have much effect at all.

Lu Lifu is also a complete novice in formation, and he doesn't know anything about the formation, so it won't play much role at all.

But a strange scene appeared, as she increased her mana, the formation became more and more fragile.

Li Nan hadn't seen the knowledge of formations either, and there were a lot of them in the Scripture Pavilion, but he didn't have time to read them at all.

He could be sure that his perception was correct, but the formations were ever-changing, and there were always things that he couldn't grasp now.

It takes time to precipitate and experience to understand all the situations.

All he can do now is wait for the results with peace of mind.

Lu Li's appearance interrupted all his plans, and it was no longer suitable to rush out, even if he believed Lu Li, it was impossible for him to hand over his life to her.

Only three people present could see the formation, and it was still a blank space in the eyes of others.

It's just that I can sense a force around me.

Half an hour later, when the mana in Lu Li's body was almost only one percent, she retreated, after all, without mana, her own danger would increase countless times.

But at this moment, the entire formation suddenly disappeared.

Then on top of the stone wall, a door appeared.

The door appeared out of thin air, and everyone was startled by the sudden scene.

And the head of the Dragon Guardian Villa was overjoyed when he saw this.

walked directly over and dripped his blood on the stone door.

Then, he instilled all the few mana in his body into the stone gate.

Generally speaking, it is impossible for an ordinary item like a stone to absorb mana.

But this door is different......

Li Nan finally understood this time, it turned out that this gate was the core of the formation, and the previous formation was just a disguise outside, and it needed to be broken with mana.

His divine sense, directed to the core, did not find the function of camouflage.

This time, Lu Li's hand was not made again, because her mana was not compatible at all.

The head of the Dragon Guardian Villa immediately took out something similar to a conch shell from his body, handed it to Lu Li, and said, "Great Elder, you can enter the mana, just speak directly into it, let the old ancestor make a move, and say that my side is all ready." ”

He had no power in his body.

It is a temporary Grandmaster third step, and all the sources of mana rely on that 10,000-year-old Flesh Lingzhi, which is less than one-tenth of the third step of a normal Grandmaster, and it is used up all at once.

After Lu Li got his hand, he didn't hesitate, and immediately hit it with a mana.

Soon, the entire conch shell lit up directly, and she passed on the words just now.

This is a magic weapon refined using a very rare spirit conch shell, which can communicate directly over a long distance, provided that it has mana.

Before, they could only hear, but they couldn't convey the message.

If Lu Ci hadn't appeared, he would have prepared two heavenly treasures, ready to forcibly restore a little mana to himself, but now he can't use it.

He was very weak, his divine sense was declining violently, and after his mana was exhausted, the true qi in his body was also wiped out, the meridians were forcibly opened, and the middle dantian was also opened, but the realm was not in place, and everything was a floating cloud.

Even in the future, he couldn't cultivate anymore, after all, he couldn't use the lower dantian to gather true qi.

But all this, he was willing.

The conch shell quickly dimmed, and there was no response inside.

But after a few minutes, the stone door slowly opened.

There was a dark hole inside, and it was impossible to see what was going on inside.

At the same time, no one came out of it either.

"Old ancestor, Zhou Zhen, the forty-eighth generation head of the Dragon Guardian Villa, is here to supply the old ancestor out of the mountain!"

The head of the Dragon Guardian Villa said to the entrance of the cave.

"How many people did you bring this time?"

Suddenly, an old voice appeared inside.

Everyone's faces were happy.

It is really the ancestor of Dragon Guardian Villa!

That's right!

Even if the voice is very unfamiliar, the person who can speak like this must not be someone else.

"According to your request, all the grandmasters are here, and the martial artists at the peak of their strength are half male and half female!"

"Well done, all come in!"

"What?"
