The murals are very traces of ancient times.

This was expected by Wang Feng, he was used to it and was not surprised.

But the things on the mural, he inevitably had a burst of novelty. All kinds of animals and plants that have died out in the long river of history are painted on the rock wall, with a clear structure and lifelike.

Mammoths, saber-toothed tigers, as well as some exotic birds and beasts, flowers and plants.

The wide stone wall is equivalent to a museum in ancient times, with hundreds of plants and animals collected.

These murals, if experts and scholars see them, they will definitely be crazy with excitement. But for Wang Feng, it seems that there is no great use except for increasing knowledge.

…… Hey, that's not right.

Wang Feng's gaze suddenly froze.

In a mural, he saw something different.

This is......

Wang Feng condensed and immediately beckoned.

An oil lamp, immediately nearby, flew over.

Under the light of the lights, the hard stone wall faintly flickered with different lights.

The dark light is very subtle. If not, his eyesight is far beyond ordinary people, and I am afraid he will not be able to notice the existence of this subtle light.

It's weird.

Wang Feng looked at it for a moment, and suddenly swung his fist and smashed it on the stone wall.

Rumble!

The force field bracelet drove a heavy force and directly smashed a stone wall. When the fragments exploded, a touch of metallic luster suddenly caught Wang Feng's eyes.

Bang, bang, bang.

Wang Feng glanced at it and immediately sped up his movements.

His fist immediately evoked layers of phantoms and smashed into all directions. All of a sudden, the rocks slapped into the air, and a heavy wave of air exploded the entire huge space, and bursts of soot were raised.

At the same time, at his command, the bird regained its form of a giant firebird.

Whew, whew.

The flamingo is empty, rolling.

The flame burns, evaporating everything.

In an instant, the empty cave immediately underwent earth-shaking changes. The vicissitudes of time, the mottled stone walls have been replaced by snow-white and bright metal alloys.

What appeared in front of me was no longer a gloomy cave.

The so-called huge pit is clearly a space made of shiny metal, tightly sealed, and carefully crafted.

Bright metal, streamlined arc, revealing a bright blue light.

Wang Feng stood in the middle of it, and suddenly smashed down with a punch.

Bang.

The hard metal suddenly concave a fist mark.

When it was him, he put away his fist.

The hard metal suddenly transformed, like flowing water, and there were slight ripples.

After a few seconds, the dented fist mark immediately returned to its original state.

Straight and shiny, as if it had never been harmed.

What is this?

Liquid metal?

Memory alloy?

Wang Feng didn't understand, but it didn't prevent him from knowing that he seemed to have found something amazing.

He looked around to the left and right.

The whole space is integrated.

Originally, it was camouflaged with stones and earth.

Even, with the coiling dragon in charge, outsiders come in, I'm afraid all the attention is focused on the dragon.

That Mr. Geography is a good example.

He didn't know, he had discovered the cave for a few years, but for so long, he only focused on studying the dragon.

I don't know anything about the cave itself.

Is this a return to the pearl?

Not necessarily......

After all, most people found a dragon in the cave.

Who cares about the cave itself.

Only his "metamorphosis" that feels different from ordinary people can find some clues.

All in all, he cracked the secrets of the cave.

In addition, it should be noted that at the time of his wanton destruction of the cave. The dragon, which showed no signs of life, also flowed again in mid-air, coiling in the middle of the pit.

At this moment, Wang Feng's gaze fell on the giant dragon again.

Until now, he could be sure.

This dragon, like the guards in the Tibetan Heavenly Palace, probably belongs to another kind of mechanical life.

It's just that, compared to the Heavenly Palace guards.

This dragon seems to have lost a very critical intelligence core.

Not only did they lose their eyes, but perhaps even the crystal nucleus of energy was not installed.

So much so that it is now equivalent to an empty shell of papier-mâché.

Seemingly, it is scary enough to fool some people.

But in his eyes, the value is equivalent to the dilapidated flying machine of the ancient city of Haicheng.

Chicken ribs, chicken ribs.

It's a pity to discard it.

Wang Feng shook his head, stretched out his hand again, and gestured.

The invisible force field directly enveloped the golden dragon in it.

In an instant, the golden dragon floated and flew into the air, revealing the last of the rocks. This rock, with a radius of several tens of meters, is very eye-catching in the space of metal structure.

Rumble!

The firebird next to him, under Wang Feng's command, immediately flew down, like a fire rain meteor, crashing into the rock.

In an instant, the rock turned to powder.

A mysterious passage suddenly appeared in front of Wang Feng's eyes.

Really......

There was a blazing light in his eyes.

He knew that this mysterious metal space must still hide secrets.

The core secret must be greatly protected.

It's a pity that the golden dragon, for unknown reasons, has been reduced to a toothless tiger, like a scarecrow.

It can scare the birds, but it can't scare people.

In the sigh, Wang Feng did not hesitate and floated directly into the passage.

Wide passageway, very straight.

Entering it, Wang Feng suddenly ...... Amazing.

This passage, or rather, this promenade, is two or three kilometers long.

Next to the promenade, it is orderly, similar to the space of the room.

These spaces, with locked doors.

So Wang Feng wasn't sure what was in it. However, it is certain that there are absolutely no living creatures in between.

He floated through the corridor, only to feel a stream of dead air fill the air.

I really want to know what's inside.

Wang Feng's thought only came to mind.

Caught off guard, a blazing brilliance appeared on his chest.

I saw the mysterious necklace crystal nucleus, and a ball of light rose, directly enveloping him like a circle.

The round light spreads suddenly.

Click, click, click.

In an instant, on both sides of the passage, one room after another, suddenly opened.

"Huh?"

Wang Feng was shocked and dumbfounded.

Immediately, he was surprised and picked up the necklace.

Permissions......

He never thought that the crystal nucleus in the necklace actually had the authority to open these access controls.

What an unexpected surprise.

Wang Feng was a little excited, but how many strong winds and waves came, he could still keep calm and immediately looked towards a room.

I saw a spacious room, at least hundreds of square meters.

In the room, there were dozens, something like a coffin.

At first glance, Wang Feng's pupils shrank, condensed like a sharp light. He was a little dazed, but also a little relieved.

He didn't look closely at these "coffins", and he didn't even bother to open them for inspection.

One glance passed by, and it went straight to the end.

The moment he approached, a thick gate also shrank and opened.

Another area appeared in front of his eyes.

This is......
