Liu Yucheng ate the two pieces of jerky handed by Xue Lang, drank some more water, and seemed to have rested, looked at the egg-sized hole, took a deep breath, spit it out and said: "The secret of hundreds of years is at this moment, I hope the mechanism will not rot!" ”

As he spoke, he shook the dragon tooth in his hand, and at the moment when the dragon tooth showed its spikes, he was about to poke into the round hole.

Xue Lang's heart moved, and Liu Luocheng's words of hoping that the organ would not be corrupted made him stop Liu Luocheng and said: "The opening is imminent, it's not bad for this time, I'll take a look first." ”

Liu Chengcheng paused, didn't force his action, and let go of the way by half a step.

Xue Lang quickly took out his notebook, connected the device in a few clicks, and carefully stretched a Vientiane probe into the round hole.

As the probe continued to go deeper, Xue Lang saw the situation inside and understood the location of the mechanism.

Inside, after about a foot in, nine grooves appeared, very small, the front end was a dead end, and at the outer root of the trench, an object as thick as a pencil passed through the trench.

After reading it, Xue Lang understood that this was the function of the nine teeth, and he didn't know why it was designed, but it was obvious that it was to use the nine-tooth blade to cut off these objects.

It is not difficult to see from the picture that if the dragon tooth is opened, it can't reach in at all, and it is not a small martial artist who cultivates Taoist or Buddhist exercises, and it is not a master of some metaphysics, and it is impossible to close the dragon tooth and open the mechanism when he unlocks the lock spell.

It seems that the restriction is here, and it must be related to the Taoist people. However, for modern means, this is not an unsolvable problem, but it is not known what those objects are, and whether the ordinary blade can be cut.

Seeing that he understood, Xue Lang put away the equipment and got out of the way.

Since the mechanisms are all there, it is entirely possible to open them.

Liu Yucheng also saw the picture, and saw that the distance was the tip of the dragon's tooth to the end, and then opened the nine teeth, and dragged it back to cut off those things that linked the mechanism.

So, at the moment when Xue Lang got out of the way, he took a deep breath again, slowly inserted the dragon tooth into the hole, and at the distance of only his hand, the moment he felt the end, he opened the nine teeth, slowly pulled back, and at the moment he touched the object, he stared still, and then pulled back hard.

Boom!

A sound similar to the breaking of a taut rope reached the ears of the two of them, and at the same time as Liu Yucheng retracted his nine teeth and pulled out the dragon's teeth, they both heard a clatter of iron chains coming from the mountain.

The two of them quickly took two steps back, standing in the sunlight, their ears carefully catching the sound.

In the midst of the loud sound, a slight vibration came from the mountain, followed by a larger tremor that continued endlessly, followed by three or four violent vibrations from under the feet, as if something had fallen.

Before the tremors disappeared, Xue Lang and Liu Chengcheng's ears suddenly heard an extremely subtle strange sound, if it weren't for the hearing of the two of them, they really wouldn't have heard it.

The sound was like the flow of water, much like the sound of a stream flowing.

The waterway is opened......

The two looked at each other, and the expectation in their hearts was even greater.

But the sound of the water gradually disappeared, and it seemed to stop flowing, and the two of them couldn't hear it no matter how they listened intently.

The trap was destroyed......

The two looked at each other again.

According to the understanding, since the waterway is opened, the mechanism should be opened.

But at this moment, an extremely slight vibration reached the ear drums of the two of them.

The two of them looked in the direction from which the voice came and couldn't help but be stunned.

It was in the direction of the waterfall, and a black, crushed mist-like object gushed out and rolled into the air.

What is that?

Xue Lang's eyes were empty, and he took out his binoculars and looked over.

At this glance, he was stunned.

Those foggy things turned out to be bats.

During the day, bats are inactive, and this will be a surprise to see bats of all sizes flying all over the sky.

I don't know what happened there, Xue Lang hurriedly asked in the headset, "What happened in the direction of ten o'clock?" ”

As soon as he finished speaking, the voice of the team member came: "Report to the captain, there are countless bats flying from the top of the waterfall here, and there are some who are not very good at flying, climbing down, most of them fall under the waterfall, do you need to go over and check?" ”

View......

Before Xue Lang's thoughts were finished, Liu Yucheng suddenly said: "The waterway is open, Wolong is about to spit water, let the team evacuate around the waterfall!" ”

Xue Lang was also suspicious of this, and when he heard this, he hurriedly ordered the team members who were hiding there at the commanding heights to leave to avoid danger.

There were really two team members there, one hiding near the current and the other hiding at a higher place, monitoring the situation on this side, and quickly left there when they heard the order.

Within a minute of their walk, muddy mud suddenly emerged from those cracks, rushing out with countless young bats and debris, rolling down the stone wall of the slope, and in just a few seconds, they fell to the ground 100 meters below.

It's really Wolong spitting water!

The moment the roar came, Xue Lang was overjoyed.

If there is water in the waterfall, then there will be one more tourist attraction here, and the bald mountain will soon turn green.

Xue Lang would really want to go over and see the scene of the waterfall flowing, and see if it was okay to use it as a scenic spot.

I can imagine that there must be a foggy place, like a fairyland.

But he didn't know where the water was muddy and smelly.

I don't know how many years the bats have been making nests there, and I don't know how much feces and dead young corpses have been deposited in the waterways.

When his mind turned, Liu Yucheng pulled him, followed the gallop to the right direction, ran out of a hundred meters, stood in a position sunken inward, squatted down, and at the moment when Xue Lang ran, he clasped the cracked sand under a boulder protruding from the rock wall with his hand.

Xue Lang looked at it, hurriedly pulled out the sapper shovel, and began to swing it, cleaning up the sand under the boulder.

As he cleared, the sand loosened and the roots slowly bulged.

He understood what was going on, he moved faster, and he dug quickly wherever he was raised, and in just a few breaths, he cleared the sand thirty or forty centimeters, revealing the rocks below.

Then, he saw the doorway, after the sand was thoroughly cleaned, the boulder came from a slight vibration, slowly moving, actually sinking into the mountain on one side, and leaving the mountain on the other, just like a door more than three meters wide and two or three meters high.

It's opened!

Xue Lang stopped what he was doing, staring nervously and excitedly at the boulder in the dust.

It's the same with Liu Defeated City, if you don't pay attention to your surroundings, I'm afraid it's really troublesome.

As the boulder moved slowly, he let out a long breath of turbid breath and said, "It's dangerous! If you find it early, it will be destroyed if you don't have it. ”

Xue Lang certainly agreed with him.

The boulder is covered by the sand below, just like the snow outside the door in the northeast winter, if it is not cleared, it is difficult to push it away with great force, and the key is that it will damage the transmission system. Hundreds of years later, who knows how much of the system is left?

The boulder did not move quickly, and in the distance, the bats flew and dispersed, and in the steaming water, the boulder moved more than a meter of gap, revealing the smooth side of the back cut.

Liu Yucheng looked at the hole that had been exposed and said, "Xiaoying, let the two of you watch here." ”

"Okay."

Xue Lang did not hesitate. He doesn't understand this, but he understands it, in case there is a mistake in the entrance, and someone outside knows about it, right?

The two team members rushed to the order, and after Xue Lang took the backpack they brought over, they used camouflage cloth to hide their figures in the rocks.

Xue Lang took out the ice cicada beads and tried the entrance of the cave, and found that there was no abnormality, and there was no feeling of air flow, and he was just about to say that he would go in and take a look, when the moving boulder suddenly stopped, and shook a few times with the sound of loud vibration, and there was no movement.

It's like a mechanical gear encountering a load overload and skipping teeth.

At this time, Liu Yucheng moved, stepped forward and pulled the rough side of the boulder, and closed it hard.

As he pushed, the boulder actually closed very easily, and when there was still a gap of a foot wide, Liu Yucheng pushed it out again, and although it looked like it weighed several tons, it effortlessly pushed the stone gate back into its original position.

After tinkering, Liu Yucheng said: "Okay, the mechanism is a one-time, the center of this stone gate is a shaft, there is no mechanism to control it, it can be opened at any time, it can not be exploded." ”

Although Xue Lang couldn't see the mechanism and transmission system, he could imagine what the principle was, for hundreds of years ago, he was really amazed to have such an ingenious design ability.

And the power, if it is not bad, should be the flow of the waterfall, which is blocked by the transmission system designed after the diversion, and then opens the waterway, uses the power of the water flow to push the transmission system, and opens the stone door.

Great wisdom!

Xue Lang sighed in his heart.

Don't say anything about the Five Elements Lock Dragon Array, just the mechanism controls, it is nearly a hundred meters here, if it is not for the mechanism to open, it is really difficult to find the portal.

Before the boulder was opened, Xue Lang did not find any artificial traces from the appearance, and the whole protruding boulder was completely natural with the cliff, and it was difficult to find it.

Admired, carefully thought about the items prepared in the bag, and was just about to bring it in again to see, when he suddenly remembered something, and was busy in the headset and ordered: "Send a kilometer phone line!" ”

"Yes!"

Lisuo, a security guard at the docks, took the order.

Entering the cave, Xue Lang didn't dare to be completely assured, he didn't know what was dangerous inside, and the necessary protection must be in place, after all, it was a few hundred years ago, who knew what would happen? Without wired communications, they can't get in touch with the outside world.

After waiting for more than ten minutes, two security guards each ran with two spools on their backs, one was 250 meters long, and the other was exactly 1,000 meters.

Xue Lang fixed the three spools on both sides of the backpack, and then carried one and asked, "Go in now?" ”

Liu Chengcheng was not in a hurry, but was very calm, and seeing that Xue Lang was ready, he nodded and said, "Let's go!" ”

Xue Lang handed the line to the two security guards, asked them to answer the phone in a hidden position, put the line, turned on the exploration light overhead, and followed Liu Yucheng into the cave.
