Could it be that this is actually a busy research room with people coming and going, but I can't see it with my own eyes?

I have seen a lot of strange things in the past year, and Lu Ran's imagination has been enriched. Pen, fun, pavilion www. biquge。 info

"Professor, I didn't see anything. Lu Ran reluctantly turned his head to Professor Xu and said.

The professor was still smiling, pointed in another direction, and said to Lu Ran, "See what it is?"

Lu Ran looked forward, and on the wall in front of him, there was a place where the material looked different from the red brick next to it, and the size and shape were like a door.

Lu Ran stepped forward and took a closer look, the door was painted with red paint, and it was indistinguishable at first glance.

But when you touch it with your hands, you will see that it is a wooden plank.

"Why is there a board here? It's a wall, and it's against a hill behind it, and if it's a door, it can't be opened from here.

Who nailed a board here?"

Lu Ran wanted to tap the board again with his hand, but Professor Xu asked him not to move forward.

Lu Ran then took a step back.

Professor Xu took out a silver pen from his briefcase.

said it was a pen, but Lu Ran wasn't sure if it was a pen.

The shape of the thing looked a little shorter than a normal pen, thick in the middle, small at the ends, and oval-shaped.

The most important thing is that its material looks very unusual, and from the outside, it is very different from the material used in ordinary pen barrels, unlike plastic, plexiglass, or ordinary metal.

It looks heavier, finer, with a silvery sheen.

It is a more precise material. This was Lu Ran's judgment at first sight.

Sure enough, after Professor Xu took out the "pen", he didn't pick it up and write, but gently pressed it on it with his thumb, and then something strange happened.

I saw that the red lacquered wooden door nailed to the brick wall actually moved.

And it was very smoothly retracted into the wall on the left. It is no different from the automatic doors in modern buildings.

Lu Ran didn't expect it to be so dilapidated on the outside, but it had such a sophisticated device inside.

After the door opened, what appeared in front of Lu Ran was not the dirt on the mountain, but a space for people to enter.

"This is, an elevator?"

Lu Ran could hardly believe what he was seeing.

"Well, it's an elevator. This is the key that controls the elevator. ”

Professor Xu picked up the "pen" in his hand and showed it in front of Lu Ran.

Then he walked in.

Lu Ran followed behind him.

The elevator is no longer made of wood as simple as this door, but is made of the same material as the pen in Professor Xu's hand, which is very modern and in stark contrast to the door.

"It's amazing. Behind this wall, there is actually such an elevator. ”

"It's just the beginning, the magic thing, and it's still to come. ”

Xu Jianfeng said to Lu Ran with a smile.

The elevator is going down, two minutes have passed, but it has not stopped, it can be seen that the place that is about to be reached is underground, and the depth is not shallow.

When Lu Ran looked this way from the road just now, there were no other buildings except for a row of brick houses on the hillside.

Therefore, this elevator should be embedded in the mountain.

That is, the place they are going to get to now, inside this mountain!

Finally, after a few minutes, the elevator stopped.

The moment the door opened, Lu Ran almost thought that he had come to a sunny outdoors.

But the reasoning just now made him quickly react, this can't be sunshine.

Such a bright white light, it must be a lamp.

Lu Ran looked up, and sure enough, there was a row of incandescent lamps embedded in the ceiling nearly five meters high.

Lu Ran didn't count how many lights there were in total, but he was lamenting that the ceiling area was really large, except for the first few rows of lights that were on, and the places where the light was dimmed in the back were not in his line of sight.

When he moved his gaze down to the angle of looking straight ahead, he was immediately shocked.

The space in front of me looked so wide, there was a hall in front of it, the size of a football field.

But the edge of this "football field" is not a wall, but a connected door.

In other words, on the periphery of this hall, there may be an unknown amount of space to extend, and I don't know how big the underground space is.

"It's huge. ”

The whole hall is large, but it is not empty. Instead, there are some strange items scattered throughout the hall.

In front of Lu Ran, there was such a thing that he couldn't understand.

There was a small pool in front of the hall, Lu Ran thought that there was a small fountain on the pool, but when he looked closer, he found that in the center of the pool, there was a column of water with a diameter of half a meter.

On top of this water column is the shape of a huge faucet, but this faucet is not connected to any water pipes, so it stands in the air out of thin air.

And the water continues to flow out of its outlet and into the pool, forming a droplet.

"Hanging faucet?"

Lu Ran looked at this interesting thing curiously.

"How's that, isn't it amazing?"

Xu Jianfeng asked with a smile.

Lu Ran looked at it for a while, then turned to look at Professor Xu and said, "Professor, this design is indeed very creative and realistic. But don't forget, I also studied psychology. This still doesn't bother me.

In the final analysis, this is nothing more than using the optical illusion of the human eye to make people look like they are hanging in the air.

With such a thick column of water, it must be easy to install a glass support inside, right?"

"Haha. As a student of my blue ocean, it seems that this exhibit is just a pediatrics for you.

Of course, it was originally placed here for ornamentation, not an important exhibit. ”

Lu Ran noticed that Xu Jianfeng called these items placed in the hall exhibits, were these things placed here for display?

Lu Ran was full of curiosity about these exhibits, and he walked behind the hanging dragon head again.

He saw a whiteboard.

It is now used in schools to teach students whiteboards, on which you can write with a special whiteboard marker, which is equivalent to a blackboard and chalk.

"There's nothing special about this thing......"

"Can you read what is written?"

A nude figure of a human body is drawn on the whiteboard, not in the same detail and specificity as a sketch, but more like a rough outline used to explain to students in biology class.

Along his limbs, body, and internal organs, many lines were drawn with pen and ink.

The lines are carefully marked with directions, and there are some English letters.

These words seem to be technical words.

Lu Ran couldn't fully understand it.

"I don't understand. ”

This diagram is a demonstration of the principle of qigong. ”
