Behind the walls is a very narrow passage, all four walls are made of cold concrete, and even the top is reinforced with steel inlays.

Chen Cong climbed over the wall and entered, but he also had to bend down and move forward slowly.

But unexpectedly, after just a few steps, the passage came to an end, Chen Cong was stunned for a moment, and patted the wall at the end, but there was a sudden shock under his feet, and the sound of machinery running.

"Boom!"

With a muffled sound, the soles of Chen Cong's feet slipped, and the ground of the entire passage fell directly.

"This ......"

He was shocked to see that this small passage was an ancient elevator.

The elevator was nowhere near as fast as today's elevators, and the descent was a little slow, but after a while, it stopped.

Chen Cong was stunned again, and secretly said that it should be that the power was not enough, and he stopped halfway through, right?

He swung his fist and tried to smash the elevator open and escape, anyway, there was spider silk, and he was not afraid of falling to death.

"Bang!"

"Hiss......"

However, when this punch fell, Chen Cong's arm was instantly shocked and numb, and he gasped.

He couldn't even smash it!

"How is that possible?" Chen Cong was shocked instantly, the elevator was not made of concrete, he was wrong, it was all metal, and the density was amazingly thick, he fell with a punch, and he couldn't even smash out a little groove.

However, after he smashed down with this punch, the elevator actually recovered, and slowly sank again.

Chen Cong was a little shocked in his heart, groping for the cold metal wall, vaguely feeling a sense of familiarity, as if he had seen it somewhere.

"Boom!"

At this time, the elevator stopped again, but this time it was really to the end, and with a "click", the metal wall in front of it opened.

Chen Cong did not hesitate and climbed out directly.

It was pitch black all around, but he had night vision, and he was not affected in the slightest, and he could see his surroundings clearly at a glance, and his face suddenly became strange.

As he had guessed before, it was a small narrow room, with a table and chair in the corner, a lot of old-fashioned instruments on the table, one of the old computers was also full of dust, it was estimated that it could not be operated, and there were many large and small test tube glass bottles all around, and the whole looked like the old real room in the sixties and seventies.

And the most striking thing is that in the other corner of the table, there are dozens of pieces of silver metal like bricks, which at first glance look like ordinary silver ingots.

The "silver ingot" has an old label with English letters written on it, and although the handwriting is very light, it is still legible.

When Chen Cong's eyes swept to those label notes, his eyelids suddenly jumped, and his face changed drastically.

What kind of silver ingot is this, this is vibranium!

If you have watched the Marvel movies, you will know that this vibranium is the main material for making Captain America's shield, and it is also a specialty of the superhero Black Panther's hometown of Wakanda, a rare metal extracted from meteorites.

The Black Panther also made this vibranium into a battle suit, and its combat effectiveness was simply amazing.

This vibranium also has a name, called sound-absorbing steel, which is one of the hardest materials in the Marvel setting, and it is extremely rare. It can absorb the oscillating energy and subsequently release a specific frequency of the concussive wave.

But how can this kind of thing exist in the world?

Chen Cong was a little shocked all of a sudden, but after thinking about it, he could save zài as Spider-Man, and it was actually normal for vibranium to appear again.

It's just that he is a little unbelievable, after all, vibranium is too rare in the Marvel setting, and the power is extremely amazing, such as the shield of the American team, even small missiles can block and shock out, such an awesome metal, it is simply a plug-in to appear in this world.

"Isn't it a prank...... Or is it just metal with the same name? Chen Cong calmed down, and always felt that the kind of metal in Marvel could not exist in this world.

But turning his head to look at the elevator, he couldn't hold back his excitement.

Because the material used for the elevator was exactly the same as the vibranium on the table, and he couldn't smash the elevator with a punch just now, but his arm was numb from the shock.

Suffice it to say that these metals are not pranks and are unusually strong.

But it can't be said that this is the kind of vibranium in the Marvel world, maybe the effect is the same, but it may not be as awesome as in the Marvel setting.

But even that's exciting.

After all, this is the hardest metal Chen Cong has ever seen, and if it is used as a material to make steel suits, it will be invincible, countless times more powerful than the rare alloy that Evelyn and Soho are using now.

What a bonus!

Chen Cong couldn't help but smile on his face, this was a big surprise.

He didn't hesitate, and hurriedly wanted to go up to the bag to remove the vibranium, and the elevator, in his opinion, the person who made the elevator out of vibranium was a brainless loser.

Therefore, this elevator cannot be wasted, and must be moved out and melted.

Chen Cong was ecstatic and climbed into the elevator to leave, but he suddenly found a huge problem.

Where's the switch?

He remembered knocking on the wall when he came down, and the elevator came down on its own.

But then the wall was opened, and it became a door, and when it was closed, no matter how much he knocked or where he knocked, the elevator did not move at all.

What's worse is that the top of the elevator is tightly embedded with the passage, and it is impossible to smash it open with brute force, and this place is still an independent secret room, whether it is underground or on all sides, it is full of real dirt, and it is impossible to dig it out casually.

Then the question is strict......

Where is the exit?

The smile on Chen Cong's face froze suddenly, if he couldn't find the switch of the elevator, he would probably be trapped here, unless Li Choufeng and the others found that they had disappeared and then found a way to dig it down from it.

That's right, dig!

Chen Cong raised his head suddenly, if he guessed correctly, the top of his head should be the corridor of the basement, although it is covered with reinforced concrete, it does not mean that he can't dig out.

But it will take a little time, it took more than half an hour to smash the wall on it just now, and the ceiling above the head is probably only thicker than the wall, and it is estimated that it will take more than an hour to smash through, but the Netherworld and the people of the other killer organizations seem to be coming soon......

"It's a big problem!"

Chen Cong's face sank, after all, he didn't expect that he would be trapped one day, and it was such a critical time.

He hurriedly picked up a piece of vibranium from the table, shook it, jumped to the ceiling, and smashed it with a wave of his hand.

"Bang!"

With a muffled sound, gray stone spilled down.

Seeing that he could smash it, Chen Cong no longer hesitated, raced against time, and continued to smash it hard, he had to get out before the other killers came, otherwise Li Choufeng and they would be in danger.
