The cave is full of water, the water is not visible, but surprisingly clear, no smell.

From time to time.

There are small fish that are not afraid of people swimming under their feet.

Now you don't need Yun you's advice. Lin Dong can feel where the mechanism is. On a stone wall in the southeast, there is a huge array hidden inside. Its upper part is several meters higher than Lin Dong's height, and its lower part is half submerged. When Lin Dong came to the waterline, a mark left by his predecessors was engraved on it.

"Is there any way?" What Yun youyou said is that it's not easy to push the mechanism underwater. If Lin Dong is not used to it, she can start it.

"This is the door to open?" Lin Dong thinks it's not too easy to open this.

"No Yunyou shakes his head, indicating that this is just the beginning.

"All right!" Lin Dong is very confident now. What he imagined was that if all the organs were of this level, it would be no more difficult. Different from the opening method of Yunyou's cognition, Lin Dong did not use his power at all, or even push this mechanism. In fact, the truth is the same. Wu Xiu uses his own energy to push the mechanism, trigger the guard array, meet the requirements, and then pass. Like Lin Dong, he gathers the energy of heaven and earth and injects it into the array map behind the stone wall. As long as the minimum requirements are met, the mechanism will automatically turn on no matter what method is used.

Buzz, buzz

With Lin Dong's energy injection, the array inside the stone wall gives out a burst of tremor.

The guard Dharma array left by predecessors wakes up from deep sleep. It has no spiritual consciousness, and it can't distinguish between good and evil. No matter who the initiator is, there are basic rules of guard. The trigger must meet the standard, otherwise it can't be opened.

Stone wall, gradually showing light, faint array.

Arrange in five lines.

The five arrays of gold, wood, water, fire and earth were gradually connected and finally joined together. With the help of the energy of heaven and earth injected by Lin Dong, they were officially revived.

When the brightness reaches its peak, the stone wall where the five element array is located rotates clockwise according to the circle of mutual generation. The huge kinetic energy drives the internal mechanism. In the roaring sound, the stone wall can move like a fish to both sides, exposing a huge round cave with a diameter of more than 10 meters. At the moment of opening, a spirit wind comes, turns into energy and floats around. It permeates the whole cave space. It is more integrated into the water before the stone wall of the five elements. The small fish living in the cave immediately rush in and rush to swallow them.

The light of the five elements array gradually disappeared, and only a small light that should be used to record time was still shining.

Two and a half hours.

After Lin Dong's careful induction, he came to the conclusion that the time limit should be about five hours.

If it can't get out at that time, the stone wall will reset automatically, and the entrants will be trapped inside.

"Ah, you open so fast?" When Yunyou was a child, he was so shocked that he was dazzled. He had forgotten the time it took for his master to open it. He could not make an accurate comparison with Lin Dong now. However, even if the opening time was almost the same, she felt as if the master had to work harder. It was not as easy as Lin Dong. He didn't work hard at all. He looked so easy that he opened the stone wall.

"That's slow, isn't it?" Lin Dong estimated that it would not take ten seconds to open the mechanism of the five elements array before the return.

"Don't you need any force to open the mechanism?" Yun youyou suddenly has a little curiosity about Lin Dong's cultivation.

"Force..." for a curious sister Wu Xiu, Lin Dong had to patiently explain: "I use another force, the energy of heaven and earth, which is the same as you push it hard, and it's not easier than you. Don't you see that I'm tired to death? It looks OK on the surface, but in fact it's not that easy! "

"It doesn't look like it!" Yun youyou didn't see it at all, and he didn't sweat a drop. Can he make a dog tired?

"Ah, with a few more such stone gates, I will become a man. Can you understand this explanation?" Lin Dong takes an example to illustrate that it's a pity that Yun youyou still shakes her head.

Or, she already understood.

I just can't see the boy's appearance. He deliberately pretends to be silly and teases him, so that he won't be too proud.

Shibi cave * * has a passage, about 20 meters forward. There are artificial carved stone steps extending up, about 50 meters, and then turning down. So up and down, winding around the mountain, about several kilometers forward, walking in front of Lin Dong with a flashlight, he found a platform in front of him. It's full of stone tables and benches. It seems that someone has lived here.

It's a pity that the items inside have been emptied by predecessors, and even the words engraved by the original owner have been scraped away with a sharp blade.

Lin Dong looked back and went to see Yun youyou: "did you pick up the black jade gourd here?"

Yun youyou shakes his head.

Yu pointed to the dark place in front of him: "far away, there are two doors in front of him, and there is a sword platform in the distance, which is the real" door "to open!"

Sword stage? Lin Dong felt a slight shock in his heart when he heard the words. Was it the sword platform sealed by the Dragon chopping Taoist? If it is, then it will be developed!

They cross the platform and move on.

About two kilometers into, and see the huge stone wall blocking the road.

"Let me open it this time!" Yun youyou volunteered. She was afraid that Lin Dong would run out of energy and become a man. When she arrived at the second organ, Shibi, she decided to do it herself and share the task.

"No!" Lin Dong's eyebrow lightly jumps, a kind of not very good premonition floats to the bottom of my heart.

He felt that there might be mountain guarding beasts behind the stone wall, which would not be as smooth as before.

In Xiuzhen cave, it's necessary to have a fierce beast to guard. Otherwise, when you go out and let the thief empty your house, can you still have Xiuzhen's face? Whether it's a panacea, a magic trick, or a treasure, these things are not for outsiders to touch. Some of them are of great cultivation ability. They can expand the whole cave into a Fairy Island of Lingshan mountain. They are comparable to a continent. There are not only guardian animals, but also disciples and their vassals. Thousands of people live in it, which is like a country beyond heaven.

Generally speaking, practitioners with the level of leader can be at ease. They don't need to worry about the cave being invaded. Unless they destroy the cave, their cave will be safe.

It's located in the sect it founded, with special personnel guarding the mountain gate.

There are also those who are independent monks and have no disciples to guard them.

Then they put some monsters around the cave.

Replace the guard.

First, to avoid the interference of outsiders; Second, you can get it when you need it, so you don't have to go far to kill it.

There are also some special kind-hearted monks who will live together with some immortal creatures to avoid the world, and they can exchange what they need with each other.

"There's a cold smell behind the door!" Lin Dong looked at Yun you strangely and told her to be careful: "it may be some monsters, or it may be the variant offspring of the mountain gate guard beast. Be careful, because these things can't be imprisoned, the whole life and cognition are distorted, often bloodthirsty, only killing instinct, without a trace of kindness. "

"I've been inside, and I know something about it. You're right. There are many big snakes, and many ugly strange insects..." Yunyou takes a big eye and looks at Lin Dong. He suddenly smiles and says, "these things are very bullying. As long as your strength is far beyond, they won't provoke you. However, thank you very much for your reminding, hee hee

"I'll open the door. You can keep your strength first. If you can't fight, we'll run." Lin Dong always thinks about the consequences before he does anything, instead of fighting a battle that is uncertain.

It's not impossible for Yunyou to open it.

If you're not afraid of ten thousand, just in case.

If you happen to meet an ancient monster who just wakes up from his deep sleep... Lin Dong has never met this kind of thing before. The whole team, a large group of 25 friars, except Lin Dong and a companion who is extremely good at hiding under Yueying, all the other 23 people are killed. At that time, Lin Dong's strength in the team was not in the top ten, and he was able to escape from Shengtian completely because of the premonition of the battlefield and caution. To this day, Lin Dong still feels chilly in retrospect.

In the process of exploration, any mistake or carelessness at any time may lead to death.

Lin Dong is tired.

You can also recover from the spirit stone, which has little effect.

As a martial arts practitioner, if you are tired, it will directly affect your combat effectiveness!

Inside the second stone wall is the inverse five elements array. The opening process is more dangerous than the first. Fortunately, Lin Dong is familiar with the five elements array, which belongs to the general array in the world of cultivation. It's not too hard to solve it, and he doesn't consume a lot of energy.

The walls of the stone rumbled open.

There is a kind of Yin Qi, like a poisonous fog, which diffuses in. If it is the will of ordinary people, it will definitely be affected by it, or fanaticism, or fear, or anxiety. In a word, all kinds of negative emotions will come to mind. Lin Dong kept his mind and walked slowly through the passage. Looking left and right, he found that the second heavy stone wall was directly in the middle of the cliff. Below it was an underground river formed after the mountain broke.

Lin Dong along the slippery steps slowly down, less than 200 stone steps, a dark river, appeared in front of him.

"It's blocked on the right. Let's go left." Yun youyou is about to lead the way. Suddenly, she finds a treasure map in Lin Dong's hand. When she looks at it under the flashlight, she finds that it's the same as the underground river, and there are some secret places she doesn't know. She immediately sweats for it. Where do they come from? How could he have such a thing?

"Are you really cute?" Lin Dong found that the girl was braver than the sky.

Barehanded, in a sportswear.

I don't have half a treasure to protect my body, so I dare to explore and find treasure... Hey, can you be a little more female? Laura of Tomb Raider, at least she has a pistol!

Yunyou gave him a white look.

It means that if you know that you don't have it, please don't say it. It makes you feel very sad!

In the dark river, several python, more than 20 meters in length, are lying lazily in the river. Some of them are hanging between the river stones and pretending to be dead. Some of them are simply hanging on their companions and twisted together in a mess. They turn a blind eye to the arrival of Yunyou and Lindong, and have no abnormal reaction at all. Yunyou walks on them calmly, constantly jumping forward with the help of river stones or body beside them.

Lin Dong looked.

Full of rain pear sweat!

Because she wore that jade pendant, although she didn't know how to use it, the creatures in the dark river instinctively felt a sense of awe.

Yunyou didn't hurt them. They didn't dare to resist and let her trample her body forward.

Lin Dong is not.

As he passed by them, the python looked on guard one after another and looked up at him until he felt that his breath was more powerful than his own. He quickly gave up the idea of having a good meal and returned to his original lazy appearance of pretending to be dead.

There are huge boa constrictors in the dark river, and strange looking lizards are crawling all over the bank or cliff. Each one is five or six meters long and is bigger than a crocodile.

When they were observing themselves in Lindong, they were also looking at this strange human.

Some of them followed him for some distance.

Lin Dong goes a little further.

From time to time, some strange insects, which look like centipedes and lobsters, emerge from the underground river. They are huge, about two or three meters long, and they are very ugly. One of them, who didn't open his eyes, thought that Lin Dong was delicious food, and tried to stab him with his claws with sharp barbs.

"To die!" Lin Dong jumped up.

Blow up the whole head of the bug.

The blue blood, as well as countless limb fragments, flew into the sky. The body of the head exploding monster was still alive. It struggled for a long time in the dark river, until its companion took advantage of the opportunity to separate it and eat it, and the life was really over. Yun youyou stood on a river stone, stopped and looked back to laugh at him: "I came here when I was nine years old, and there was no insect bite me. You must have bad character!"

Lin Dong wanted to tell her that if you take off the jade pendant, it's strange that the insects don't announce the meal!

Words rushed to the mouth, and finally did not say it.

It's just for the sake of Moyu gourd.

Yunyou's sixth sense is very strong. As soon as he feels a little uncomfortable, he can understand his meaning. He can't help apologizing: "Lin Dong, it's my fault to put you in danger. If it's really dangerous, let's go back. I can't let you take risks just because I want to fulfill master's wish."

"Forget it, I've already come here. Don't say it's nothing. It's just that there's a sea of fire ahead. I have to make a breakthrough." Lin Dong quickly comforted her.

I've just finished.

In the distance, in the dark river two kilometers away, a huge head suddenly rises, which is extremely ferocious
