Golden Forbidden Land: I am at the highest level, exploring the secrets of immortality

In theory, ordinary iron gates are not several meters high, and the iron gate in front of us can't even be called a door, but a city wall. It's several meters high, and you can't even touch the top. The iron wall is rusty, and the largest lock weighs dozens of kilograms and is completely corroded.

There is no gap at the bottom of the door closest to us.

Strictly speaking, this is completely like a secret military base.

No fly or mosquito can fly in.

And this huge iron door should be divided into several parts and combined together, so there are still big traces at the joints. Even so, the traces of welding, plus the rust, have been perfectly fitted.

"It seems that this door is completely sealed."

Facing this door, although we tried our best to find this entrance, we couldn't get in at all.

"But how did those devils get in back then?"

Mu Shi and Mu Na were a little puzzled.

This project is obviously not low, and it is impossible for ordinary people to complete it in a short time. It is completely equivalent to the structure of an ancient royal tomb. But it took at least hundreds of people to build it, and it took half a year to build it. However, all the craftsmen were buried alive because of the location and structure of the mausoleum.

"No, this is the last time they sealed this door."

I thought.

I think the devils knew that they had been defeated and were ready to escape, but they couldn't take away some of the things under the project, and they couldn't bear to destroy it, hoping that they would see the light of day again one day, so they sealed this door.

In other words, when they left, they almost poured copper liquid on the exit and the only entrance.

"Then there should be a lot of good things looted by the devils in the underground?"

Mu Shi said.

"Of course, there are also some supplies and armaments of the devils during the war. If I'm not mistaken, they should all be inside this door."

I stared at the door.

"But now we can only look at it."

Muna sighed.

"Yes, if we can't get it, it's all in vain." Mu Shi stared at the surroundings, and there was absolutely no other entrance or passage.

"Do you think we have any other options?"

We didn't seem to give up, and finally came here after escaping death.

"Do you think there is really only gold and silver treasures behind this?"

Mu Shi said.

"That's not necessarily true."

Muna pondered.

"What?"

"Maybe there is some secret behind this, at least the mysterious people who control us may know." I said. I thought to myself that this could definitely be a conspiracy, but I don't know their true intentions yet.

Maybe the truth will be revealed if we push open this door.

But now we are completely indifferent and can't open this door at all.

"What should we do?"

Everyone was a little depressed for a while.

"Maybe!"

Mu Shi walked over at this time and knocked on the door carefully. A heavy sound came from behind the door. Obviously, this is a solid iron door. According to the echo, the thickness of this door is at least thirty centimeters.

That is equivalent to a highly protected armored vehicle.

Even if we have a cannon in our hands now, it is absolutely impossible to penetrate it.

"Hey, do you think there will be a mechanism here?"

I suddenly thought.

"Yeah, why didn't I think of that."

Mushi slapped his head and said seriously.

"Look for it."

I ordered.

So, the three of us tried to move all the stone slabs on the ground, as well as the strange marks on the wall.

"Look for it quickly."

We almost didn't stop.

Everyone was in a hurry. The stones on the ground were arranged strictly in a certain order. I even suspected that these stones were exactly the same, even the carved patterns were exactly the same. However, it was really not easy to find different ones with so many stone slabs.

And we couldn't understand the words recorded in the notebook.

"Look!"

Suddenly, Mushi stared at a very strange stone slab in front of him. Sure enough, after wiping the dust off this stone slab, it was a little different from the other stone slabs, and there were obvious differences in the patterns and designs.

"I'll try it."

Mushi said at this time.

He went over and pressed the stone slab directly. Sure enough, as soon as the stone slab was under external pressure, the whole stone slab sank.

"Bang!"

Suddenly, I felt that the door was obviously shaking.

The three of us looked at each other, and we couldn't help but feel secretly happy.

It seems that this is the mechanism.

Soon, a piece of welding plate on the lower right corner of the huge door seemed to fall off, and then fell directly to the ground, raising a huge cloud of dust.

"Okay."

Now we were relieved.

"Finally opened..."

As soon as the voice fell, we knew that we had completely miscalculated, because after the iron plate fell, it was not an entrance to the underground project, but some green gas came out of the door panel.

It rose into the air instantly.

Like burning garbage...
