A long iron rope was pulled up by the Golden Treasure Ti.

"What is this?"

When everyone saw it, they were stunned.

"I don't know. ”

The golden treasure is also a little difficult to pull up. The muscles in his arms bulged, his teeth were clenched, and he gasped: "It's stuck, I can't pull it up......"

It's not that it can't be pulled up, but it can't be pulled out.

Everyone looked at it and found that one of the iron cables drawn by the golden treasure seemed to take root in the ground.

No matter how hard he tried, the iron was so tight that he couldn't pull it out.

“…… Perhaps. ”

Xiao Jingxing rolled his eyes, "Could this be a mechanism or something? Not only a mechanism, but also other fasteners, which need to be coordinated together before starting or opening something." ”

When the others heard this, their hearts moved, and they immediately lowered their heads to look for it.

Zhang Chu took two steps, shone the flashlight carefully, and then said happily: "There really is...... Over here. ”

Click.

As soon as he stepped on it, a small plank was broken, and a pit appeared.

To be exact, this is a groove in which there is also a chain buckle.

He reached out and twitched.

"It's ......"

Casually, others have also made discoveries. In the adjacent area, there are at least eight loops, connected to the iron cables. I don't know what the purpose of these iron cable buckles is.

Due to their age, these iron cable loops inevitably have an extra layer of rust powder on the surface. However, after everyone checked, the texture of these iron chain buckles is still relatively hard, and it is obvious that the rust powder has not completely corroded the inside.

So an individual pulled hard, but the iron rope was still pulled out.

Whoa......

In the sound of rubbing, iron cables rose from the ground.

And then......

The crowd looked at each other and waited.

"Boom!"

Caught off guard, a dull sound came into everyone's ears.

"Sure enough......"

The golden treasure is colorful: "It's really a mechanism." ”

Everyone was a little excited, but also a little apprehensive. Mainly, the rumbling sound is not only like thunder, but also a little shaking on the ground and rock walls of the entire cave.

Dust fell like frost and snow.

For a while, everyone was also a little worried about whether this cave would collapse.

Click, click.

Under the watchful eye of everyone, the ground shook violently, and a wall was about to collapse......

Hey, that doesn't seem right.

Everyone hurriedly looked back, only to see the rock wall that was cut like a well, belonged to the window, and reflected the sunlight, slowly leaning outward. Outside the thick rock wall, there are many vines hanging down.

At this time, under the crush of the heavy rock wall, these vines broke and collapsed.

Dull dust and fresh air mix with each other.

One by one, the air masses circled, the fallen leaves and flower petals flew, and everyone was dumbfounded.

What's going on?

The crowd was puzzled, but what should have happened was not diverted by their wishes. The huge rock wall eventually slopes down, just like a suspension bridge in an ancient city, slowly changing from a vertical state to a tiled state.

The dust dissipated, and the sunlight in the abyss was no longer blocked at all, and all flowed in.

The dark and dim cave suddenly became warm and bright.

But the key is ......

It's tall and thick, and everyone has always thought that it was the existence of a wall, but it has become a ...... A door?

Or rather, a bridge?

Everyone was a little dumbfounded, and after a long time, Wang Feng came back to his senses first and walked over lightly.

He soaked up the sun and walked to the "bridge".

It's a hollowed-out bridge. When the bridge was erected, it was a huge rock wall. When you put it down, it is a bridge that almost fills the bottom of the abyss and covers the lake.

It's just that Wang Feng can't figure it out, what is the purpose of building this bridge?

He looked up and noticed. On both sides of the bridge, there are huge iron cables, which pull the bridge so that the heavy bridge will not fall directly.

Perhaps the hollowing out and cutting "window" is not only to make the bridge stand up and act as a wall, but also to reduce the weight of the rock wall.

Otherwise, it would not have been possible for the iron cable to involve such a heavy rock wall.

“…… Intriguing. ”

At the same time, Huang Jinbao and others also walked out cautiously. They stood on the bridge, looked at the lake below, and then looked up at the sky, and their minds were in a trance.

At this moment, they were at least twenty or thirty meters away from the lake below. Further up, there is the top of the abyss fifty or sixty meters high. Now they are in the middle.

I can't go up to the sky, I can't go down to the ground, the cold wind is cold, and there is an indescribable state of mind.

"Why?"

After watching it for a long time, everyone calmed down, and naturally such questions arose.

This "door", or rather, this "bridge". It is impossible to say how practical it is. If it were just, purely decorative, it would be even more ridiculous.

A rock wall nearly 100 meters high has created a thing that integrates the bridge and the door.

This is definitely not a small project.

And between the rise and fall of the bridge gate, it must require the cooperation of many people to pull and lock.

The manpower and material resources consumed are not a few.

Why do such a thankless job?

There must be a key factor in this.

Wang Feng groaned, and others were also speculating. But for a while, they didn't have a clue.

"No, it's easy to get in, right?"

Zhang Chu said softly: "It doesn't make sense." ”

"Tuk, tuk. ”

Huang Jinbao squatted down, took a small hammer, and knocked on the bridge door.

After only a few knocks, his body suddenly stiffened, and then exclaimed excitedly: "Ahhhh

"What?"

A few people next to him were stunned and looked around.

At first glance, they were also stunned, and were surprised to find that the stone bridge seemed to be painted with a layer of concrete.

It's just that just now, everyone noticed that they were attracted by the tilt of the bridge, and the rock wall itself, which was covered with a layer of dust and dirty, so naturally no one cared.

But now, the golden treasure itched his hand, and pieces of dust and mud collapsed.

"Whew!"

He blew away the dust and wiped it with his hand.

A glimmer of light came into everyone's eyes.

"Ahh ”

At the right time, everyone realized that the so-called rock walls and bridge gates may not be stones.

Everyone looked at each other, their eyes burning.

"Ata. ”

Huang Jinbao did not hesitate, directly picked up the hammer, turned into a hammer madman, and slammed it. In an instant, thick pieces exploded on the gate bridge. Dense spider patterns began to spread.

Others are also helping to peel off the spider cracks.

Soon after, everyone didn't know whether to be surprised or happy.

Anyway, everyone fell into a deep shock. I saw that under the sunlight, the entire abyss was full of light, and a colorful rainbow light rose directly into the sky, piercing the sky......
