There is a small bridge in front of two stone peaks.

The bridge is natural. In fact, it is a huge stone, but it is slightly flat on the top and there is a cave with a diameter of more than two meters below, through which water passes.

On the other side of the bridge, there is no way to find.

Mohist children wave knives and cut a path that only one person can pass.

Further ahead, there are towering mountains.

Most of the mountains here are made of stones. The soil between the rocks feeds these trees and weeds.

Mo Lao took the compass and carefully identified the aspects.

Maybe no one has come in for many years, and it's not as easy to find the entrance as many people think.

Mr. Mo has been watching for a long time, his brows are tight, and he doesn't speak for a long time.

The crowd followed, waiting for Mo Lao to speak.

Mo Lao was silent for a long time. He pointed to a weed on the right and said, "you split it here."

Several Mohist children quickly removed the weeds and removed the turf and soil.

"Mo Lao, I didn't find it."

"No! It should be this position. "

Mr. Mo said to himself, carrying a compass.

Are you wrong?

He pondered for a while, "dig a little more to the side."

Several Mohist children continued to dig. After a while, someone yelled, "Mr. Mo, I found a dent the size of a palm."

Old Mo was overjoyed, "that's right!"

"Clean it up."

Mo Lao handed the compass to Mo Zifei and took the command.

After several Mohists cleaned up the place, a palm sized dent appeared in front of everyone.

The shape is almost the same as the order of Mohism.

Mo Lao used to clean up all the dust carefully, and a handwriting gradually appeared in the dent.

The ink character of seal style.

Old general Mo closed the talisman gently and pressed it hard.

The rune is deeply dented and flush with the surface.

Click - click -

the sound of the mechanism came from the mountain.

People even step back, in front of the weeds, dust falling.

With the sound of the mechanism getting louder and louder, it seems that something is running in the mountain.

The mountain kept shaking, and the sound lasted nearly two minutes.

These two minutes have made everyone feel that they have been waiting for a long century.

Kaka -

on the stone wall of the mountain, there is an irregular crack, which is very consistent with the trend of the whole stone.

If there is no mechanism to open, absolutely no one will think that it is a door to enter the treasure.

Moreover, over the years, the tiny cracks have been filled with dust and weeds. Even Mo Lao just couldn't see the clue.

The Mountain Gate gradually opened, and the sound of the mechanism stopped suddenly.

A dark cave appeared in front of my eyes.

In the cave, a cool wind came.

Qin Mu instinctively pulled them behind to ensure their safety.

When Mo Lao saw the door open, he asked someone to light the torch.

Then the group of people went into the cave.

This time, we were well prepared and brought all the necessary equipment.

In order to avoid ironware, many things are specially processed.

Inside and outside the cave, it's really different.

Because of the long-term closure, the cave is dark and humid.

If you wear less clothes, it's a little cold.

Qin Mu to Lu Yaqing two humanitarian, "you follow me closely, don't go too far."

In addition to the spare torch, there is a flashlight in the backpack of Mohist children.

It's just that the torch can detect whether the oxygen in the hole is sufficient, so as to ensure everyone's safety.

More than ten meters into the cave, there is a spacious open space, flat incomparable.

Qin Mu looked at it carefully, and there was no trace of carving. It should have been accumulated over many years.

This space can hold about 100 people.

On the top of his head, however, there are a lot of stalagmites, which are all in a great variety.

I don't know how many there are.

Mo Laodao said, "the place you are standing now seems very safe, but in fact, the top of your head is full of hidden arrows. If you don't use the command to open it, but destroy the mechanism to break in, these hidden arrows will come out of the stalagmites and pierce the hearts of the intruders. "

Everyone was shocked. It turned out that the stalagmite on the top of his head had a hidden murder.

If all the arrows are fired at the same time, I'm afraid most people will not be able to escape.

Seeing this, I can only sigh about the subtlety of the Mohist's mechanism. It's just wonderful.

There is a huge stone in front of it, with a very smooth surface.

There is no trace on it. Next to the boulder is an open nine curve road.This bend is very strange. It should have been trimmed by hand.

Mo Laodao said, "this huge stone is actually a warning sign, called jiebingyan."

"It means that those who enter here must lay down their weapons. Now you will throw down all the iron objects on your body and enter the underground palace formally. "

They all threw down their ironware and prepared with their backpacks.

Qin Mu tightly holds Lu Yaqing's hand and follows Mo Lao and his party through the nine curves.

As he walked, Qin Mu felt a slight shock. He already felt that his feet were empty.

The road of Jiuqu is indeed man-made.

Mo Laodao said, "don't underestimate this Jiuqu road. If you didn't use the Jiebing blade when you passed through jiebingyan just now and still carried iron weapons through, this Jiuqu road will be closed and people will be killed here."

The crowd was in an uproar and astonished.

Sure enough, as Qin Mu expected, this road was set up artificially.

No wonder it's so zigzag. The original purpose is to prevent someone's martial arts from being too high and pass through here quickly.

With these nine twists and turns, no matter how good your martial arts are, you can't escape death as long as the mechanism is touched.

The organs of Mohism are really extraordinary and unique in the world.

Through the road of Jiuqu, there is a big black hole in front.

Inside the cave, there are grotesque rocks and stalactites everywhere.

There are piles of stalagmites.

No one knows how deep the cave is. According to Mo Lao, the cave stretches for more than 30 kilometers and has no end.

It's hovering under the whole mountain, running through the whole range.

Mohist ancestors once thought that it had gone out of the national boundary, but they did not expect that it had reached the edge of the national boundary and turned back.

Moreover, there are numerous caves, large and small, which is a kind of natural labyrinth.

without a map, you can't go out at all.

Qin Mu feels that Lu Yaqing's palm is sweating. He turns around and finds that Da meiniu is nervous.

Cheng Xueyi is much more relaxed.

"Are you all right?"

Qin Mu asked.

Lu Yaqing pursed her mouth and shook her head with a smile.

Through at least 200 meters away, seven turns eight turns.

"This chaotic stone formation is arranged according to the five elements. As long as one step is wrong, ordinary people can't go out at all."

Mo Lao introduced.

"There are gates of life and death in those intricate caves. Those who enter the gate by mistake will have serious consequences."

Qin Mu asked, "how long will it take us to get to the underground palace?"

Old Mo said, "just open the second door!"

The second door is about 100 meters underground.

People were surprised to see strange ditches crisscross the ground.

These gullies have almost no regularity. They surround the whole underground palace.

Every ditch is four or five meters deep, Qin Mu carefully looked at all this, "what's the role of these ditches?"

Mo Laodao said, "young master, these ditches are powerful. If you touch the mechanism, it will lead to the fire and submerge the whole underground palace."

"So we should be very careful not to move, otherwise the gods can't save you."

They were a little frightened. Under the leadership of Mo Lao, they came to a magnificent palace.

The entrance to the palace is locked by two natural huge stone gates.

There is a great momentum that one man is in charge of the pass and ten thousand people are not allowed to open it.
