"Are you sure you can open it?"

Standing in front of the huge stone door several feet high again, Lin Ming looked up at the stone door that had no gaps at all, and he was still a little worried in his heart.

The greater the expectations, the greater the disappointment.

It was not easy to find an opportunity, if it didn't work this time, Lin Ming was not too sure that he would be able to find other space doors.

"Don't worry, although I haven't been to this place for more than ten years, the way to open it is only in my hands, if I can't open it, then I'm afraid we can really die in this world."

Turning his head and smiling at Lin Ming, the expression on Mengyue's face looked very confident, which somewhat relieved Lin Ming.

Old death here?

That's impossible.

Reaching out and feeling something with an extremely strange shape, something similar to a lock, Mengyue took a deep breath, and then squatted down to brush the gravel on the ground.

Lin Ming stared intently at Mengyue's movements, and soon found that a groove had appeared on the ground.

It turned out to be here!

No wonder he couldn't find it before!

He had almost touched the top and bottom of the stone gate before, but he had not searched the ground.

"This door has been around for an unknown number of years before I came, and if it hadn't been for the fact that it hadn't appeared directly inside the door, I'm afraid I wouldn't have known how to open it.

You stand away, the stone door hasn't been opened for a long time, and I can't predict what will happen inside. ”

Lin Ming jumped away as he said, staring cautiously at the side of the stone gate.

I saw Mengyue align the lock with the groove and press it suddenly, and then I heard the sound of mechanical gears turning.

There was a muffled pop.

Hearing this voice, Lin Ming couldn't help but secretly rejoice.

Very familiar sound.

The sound of the door opening at the foot of Lingyin Mountain was the same, and it seemed that his previous guess was indeed not wrong.

The same people were supposed to have built the door, or the same technology was used.

soon

Under Lin Ming's gaze, the stone gate slowly opened.

As the stone gate activated, Lin Ming soon noticed that the transistors under the corner of the passage wall that he had buried at any time seemed to have a light flowing slowly.

"You don't have to look at it, the things behind the stone door also need energy to be maintained, although this planet is not barren, and the mineral deposits containing energy are also very rich, but there is no equipment and it can't do anything, and it can't refine the energy needed at all, if I'm not mistaken, those transistors should be transmission devices that absorb energy from the outside."

Seeing the somewhat surprised expression on Lin Ming's face, Mengyue slowly spoke.

Took a deep breath.

The strength of his hand increased a few points again, and the stone door was finally fully opened as the lock was completely submerged in the groove.

A rumbling sound came from under his feet.

Lin Ming couldn't hide his excitement in his heart, and his eyes were staring at the direction of Shimen.

"And where does all this energy come from?"

Since he couldn't refine the energy needed, Lin Ming was indeed curious about where the energy needed to maintain the equipment behind the stone gate came from.

The problem of energy has always been a major factor that has plagued the earth's technological progress, and if this problem can be solved, Lin Ming can guess what kind of changes will occur without even thinking about it.

"The sun, and the moon!"

"You mean it's solar? No, could it be that the light of the moon can also produce energy? ”

Although Lin Ming is not a space expert, he also knows that the moon cannot shine on its own, and the moonlight seen under normal circumstances is actually just a reflection of the moon's sunlight.

Although this light comes from a star, the energy contained in the light is almost negligible.

"Who told you it was a moon?"

however

Mengyue's words suddenly made Lin Ming stunned.

Not the moon?

What is that?

Lin Ming remembered very well that on the top of the White Bird Star, in addition to a sun similar to the earth, there was also a "moon" that was much larger than the moon on the earth, and even at night, the light emitted was much stronger than the one on the earth.

"Lonely and unheard, if it weren't for your ability to teleport into outer space, I would have wondered if the place you came from was a primordial life star like here."

Touching the tip of his nose, Lin Ming felt a little embarrassed.

"That...... In fact...... What you said isn't entirely wrong, either. ”

Although Lin Ming didn't know what the characteristics of the so-called primordial life planet in Mengyue's mouth were, to a certain extent, the earth was indeed not a very advanced civilization in the universe.

Out of space?

It is indeed possible to achieve it with the accumulation of technology by humans on Earth for more than 100 years, but it is actually impossible to carry out long-distance cosmic teleportation.

If it weren't for the space gate left behind by the aliens, he really wouldn't have been able to cross such a long distance in space.

"What do you mean?" Mengyue was a little puzzled.

She was not very old when she came to White Bird Star, strictly speaking, she was still an underage girl, she had not received systematic transmission of civilization knowledge, and she did not know much about space civilization.

Most of the introduction to space civilization in her mind was also obtained from the wisdom brain on the spaceship that brought her to Shiratori in the first place.

"I can't tell you about the specific problem, but that's the case, although the place I came from has also entered the era of science and technology, but the technology is still limited, far from the point you said.

This question will be known when you go back with me, you tell me first, if not the moon, what is it? ”

Compared with exposing his own shortcomings, Lin Ming is more interested in this issue.

As for what kind of civilization the earth has reached, Lin Ming thinks it is better to wait for Mengyue to discover it by herself.

Especially since it's unclear exactly what the identity of this guy is.

"It's very simple, since the light it emits can be used, it means that it can emit light itself, if I'm not mistaken, that planet is also a star, but it has existed for too long, it is currently in a state of decline, and now it is gradually dying."

I see!

Lin Ming couldn't help but gasp when he heard this.

A star in the midst of death is indeed rare.

Unlike human deaths, which occur almost instantaneously, the death process of a star is extremely long, which can take hundreds or even thousands of years, and eventually becomes a super-large red giant.

"Okay, it's already open, you come with me."

Without explaining more, the stone gate opened, and Mengyue immediately took Lin Ming into the stone gate.

As soon as Lin Ming stepped in, he immediately found that the situation seemed to be a little different from what he expected, and the air did not have any peculiar smell.

"This grotto has an air circulation system, and as long as the energy is supplied properly, everything inside will function normally.

For advanced interstellar civilizations, these things will be used for a very long time, you won't know this, right? ”

Glancing at Lin Ming with some disdain, Mengyue seemed a little incredulous that this guy didn't even know this.

"Hehe, you know, I'm not too excited to remember!"

In fact

Lin Ming was already so shocked in his heart that he couldn't speak.

it!

That's amazing!

Such an awesome technology!

Get rich! Get rich!

It's a complete set of energy-using techniques, if you can bring these things back...... That......

The idea of entering Baoshan immediately popped into Lin Ming's mind.
