Ye Feng really didn't believe that there would be no road in this secret passage, otherwise, what was the point of building this secret passage?

Isn't it fun!

Spending so much time and energy just to build this useless secret passage?

Don't say Ye Feng, even if you are anyone, you won't believe it.

But now.

He had been in for more than twenty minutes, but he still hadn't seen any room, much more, just a dark, narrow, corridor-like passageway.

It's incredible.

Three more corners.

Ye Feng's tissues had run out, however, the bats behind him not only did not decrease, but became more and more, and the sound continued to come, making Ye Feng's face a little pale. However, Ye Feng is not a master who gives up easily, he believes that there is definitely another way in this passage.

Suddenly.

Everything around seemed to be quiet, as if in an endless dead silence, and the voice from behind unconsciously disappeared.

As the sound faded, the red light that filled the void gradually disappeared in the darkness, and not a single bat was nowhere to be seen.

What's going on?

How did they disappear?

Ignorance.

Now he doesn't have time to think about it so much, it's better not to chase him, he also has time to breathe a sigh of relief.

"Whew!"

After running for a while, after confirming that the bats behind him had indeed disappeared, Ye Feng breathed a sigh of relief, the whole person felt like a deflated balloon, leaning against the wall, panting, after a while, calmed down, his face improved slightly, and then continued to move forward. Suddenly, not long after walking, Ye Feng stopped again, because he noticed that there seemed to be something in front of him!

Thereupon.

Ye Feng quickened his pace, and soon, a door appeared in front of him.

That's right, it's a door, and it's still a cyan iron door, the iron door seems to have gone through a long time, extremely old, and it looks a little dilapidated, the paint on it has begun to fade, obviously this iron door is at least a few decades old.

He said, well, how could this secret passage be so simple.

From the outside, this door is no different from ordinary iron doors, the only difference is that this door does not have a keyhole, not only that, but the entire iron door is bare, and it seems that it cannot be opened by ordinary methods.

Is it another organ?

Since entering this secret passage, Ye Feng obviously felt that everything here was full of weirdness and weirdness, and with the large group of bats that suddenly appeared just now, Ye Feng had to suspect that this iron gate might really be a mechanism gate.

I thought it was a door.

Ye Feng glanced around, and the surrounding area was the floor except for the wall, if it was really as expected, then this mechanism was either on the wall or under the floor.

With that in mind.

Ye Feng tried the method in the TV series, came to the wall on the left, and knocked on it, according to some reasoning dramas, if it is hollow, it means that this stone brick can be removed.

But Ye Feng tried all the walls on the left and right, and none of them were hollow.

Since the switch isn't on the wall, it should be on the ground, right?

Then, Ye Feng didn't hesitate, he squatted down, put his ear close to the ground, and then tapped the floor with his hand.

In just such a while, Ye Feng tried more than a dozen floors in a row, and tried them all within two meters around, but unfortunately, he still didn't find the location of the switch.

Strange, how can this be?

According to his guess, the agency should be around here?

Or is he not finished?

As soon as this thought came to mind, Ye Feng shook his head, the position within two meters is probably the most suitable, the position of the switch cannot be too far, theoretically speaking, his guess is right.

But why didn't you find it?

Or.... Is he pretending to be smart?

This iron gate is not a trap door?

Ye Feng, who didn't believe in evil, checked the iron gate again, but there really wasn't any place where he needed a key?

It's weird, it's so weird.

Ye Feng touched his chin, squinted his eyes, looked at the rusty iron door in front of him, and thought about the places where the switch could be hidden, but he still didn't know where the switch was hidden.

A moment later.

Ye Feng suddenly raised his head and looked at the ceiling, just now he had been looking for the wall and the ground, but only the ceiling was missing.

The ceiling doesn't look very high, just over two meters, which is unusual in any construction project, and it is very wrong.

Ye Feng tried to knock on the ceiling above, to his disappointment, he didn't find the original hollow switch after knocking a few times, but he was not discouraged and tried all the surrounding two meters.

Instantly.

Ye Feng's expression was shocked, his eyes stared at the sky, when he knocked it just now, it was actually hollow, could it be ......

Without thinking much about it, Ye Feng raised the light on his mobile phone to shine on the ceiling, observed carefully, and continued to knock on the ceiling, and immediately, he suddenly found that there was a long gap on the edge of the hollow position, if he didn't look carefully, he couldn't see it at all, and sure enough, the switch was here.

But the next moment, he was helpless.

The gap is too small to be removed.

If you have the tools here, it's fine, but the point is that there is nothing here, how do you take them out? Could it be that you really want to forcibly break your arm?

Forget it.

Ye Feng thought that his physical body had not yet reached the point where his golden body was not bad.

There's one thing, though.

He wondered, if it was a switch, how did they turn it on? Also with tools? No, it shouldn't be.

Suddenly.

Ye Feng's heart moved, since this is a trap door, will this switch not be opened by ordinary methods!

Come to think of this.

Ye Feng immediately groped on it, as if he was looking for something, and then pushed his hand suddenly, and something strange happened.

Seeing this scene, Ye Feng looked happy, and sure enough, as he thought, this position did not need to be taken out from below, as long as it was pushed to the left or right, just like an automatic door.

I have to admit that the designer of this passage is really amazing! Even such an ingenious design can be imagined, judging from the degree of concealment of this mechanism, the contents of the iron door are probably beyond their imagination.

I don't know why.

Ye Feng began to look forward to it.

Without any delay, after pushing it open, there was really a switch inside, and Ye Feng pressed the switch without hesitation.

Thundered.

In an instant, the sound of shaking the earth and shaking suddenly sounded, and the earth trembled violently. Immediately after, Ye Feng saw that the iron gate slowly opened, just like the gate of hell opening to the world, and like the ancient stone gate reappearing in the world, it was extremely shocking.

As the iron door opened, a burst of thick dust came to his face, making Ye Feng can't help but cover his nose, and hurriedly retreated, and at the same time, he also used his hands to scatter the dust in front of him.

After a while.

The dust gradually dissipated

Ye Feng exhaled, at this moment, his steps were a little heavy and a little nervous, he closed his eyes, took several deep breaths in a row, and then, when he opened his eyes, a trace of resoluteness and dignity flashed, and he raised his feet and stepped in.

As soon as he entered, a faint smell came, which made Ye Feng frown, and a pair of eyes swept away the environment in front of him.

It was a hugely empty and desolate place that didn't look like a room.

There wasn't much inside, just a few strange things, and various characters and patterns were carved on the surrounding walls.

Correct.

What made Ye Feng pay attention was not those words and patterns, but the surrounding stone platforms, which were all made of bluestone, and there was a layer of transparent glass windows on the stone platform, which looked strange and revealed.

I don't know if it's Ye Feng's illusion, these stone platforms make him feel a little chilly, and his back bones feel cold and cold.

Ye Feng came to one of the stone platforms, his eyes were extremely heavy, and he was surprised, he found that this stone platform was just suitable for the human body, just like an ice bed.

Ye Feng, who was sent by the ghost, actually reached out and touched this stone platform, to his surprise, the feeling after the tentacle was extremely silky, like snow-white skin, which was very strange.

"It's a strange thing."

Ye Feng said as if talking to himself, he withdrew his hand, and was about to walk away when a strange hoarse voice appeared out of thin air.

"It's a green bed, and it's an important tool for conducting human experiments."
