Beneath Deep Space

Yu Yifeng suddenly felt happy, and he also heard people giving each other high-fives in surprise.

But he didn't dare to neglect, and quickly praised the ocean a few times. Suddenly, the little ball started spinning happily, forgetting the unhappiness just now...

"Okay, now maneuver the unmanned submarine closer to the door...slower, must be slower."

An operator nervously controlled the submarine and swam toward the target area.

A few minutes later, it passed the entrance smoothly and unusually, and slowly explored inside. Because of being soaked in sea water all year round, you can clearly see from the screen that there are a large number of coral reefs attached to the walls, and some places are very narrow.

In fact, the moment they passed the entrance, most of the people's hair stood on end, their concentration was extremely high, and all kinds of weapons were ready to be activated, for fear that some strange enemies would emerge from inside.

That kind of hope and worry... are mixed together, and the emotions are difficult to really distinguish.

Even Yu Yifeng was sweating... Such a complete base might still be sending signals to the outside world! This is not comparable to a Martian flying saucer that has been broken for millions of years!

A civilization with a higher technological level than humans always has certain dangers...

Even if the other party just left something casually, the civilization level is one level higher, which is equivalent to a huge theoretical gap, equivalent to the unknown... The unknown is always scary.

But after seeing the dilapidated scene inside, everyone felt a little relieved.

"I thought about it, it's the greenhouse effect!"

"... This was originally a small hidden island. Due to the global greenhouse effect, it was completely submerged by the sea... I guess no matter how smart the aliens 30,000 years ago were, they would never have thought of this."

Dr. Rimbaud had an idea and analyzed the specific reason: "Look, there are traces of rotten wood outside. It may be the trees that originally grew on the island."

Everyone was relieved. This was very possible, because the greenhouse effect had only occurred in the past few decades, and the rise in sea levels had directly flooded the island...

Some people also speculated optimistically: "Maybe... the facilities inside were damaged by sea water?"

But the good times didn't last long. During the exploration process, the submarine suddenly saw a thick gate blocking the way forward.

There's also a glowing red light next to the gate!

There is no coral left in this area, and it is extremely clean, as if something has just cleaned it. People's mood was slightly tense, and many pairs of eyes stared at the submarine as it moved forward slowly.

When the submarine approached the gate, suddenly, the surveillance screen representing the submarine dimmed...

In less than half a second, it went dark without any warning!

"ah!"

Several extremely focused soldiers were startled and almost pressed the weapon button in their hands. Yu Yifeng reacted the fastest and immediately shouted: "Don't panic! Nothing is coming out. Send a few more submarines over, one after the other a few meters apart, to see what happened!"

The operator quickly entered data on the platform, and soon, five more submarines swam in slowly, maintaining a certain safe distance from each other.

…A submarine begins to approach the gate.

In an instant, the screen representing the submarine went black again.

But in the eyes of the submarines at the back, the submarine in front just... disappeared inexplicably.

Disappeared?

Yes, gone.

"try again!"

Another submarine began to approach the gate. This time, at the moment it disappeared, people finally saw clearly: when it was very close to the gate, the entire submarine turned into a pile of powder-like things in a few tenths of a second, and then quickly disappear into the sea.

The whole process... takes less than 0.5 seconds!

Without slow-motion playback, it would be really difficult to distinguish based on the resolution speed of the human eye.

Everyone at the scene said nothing, and everyone looked unhappy.

In fact, this situation was expected in advance. How could a normal alien scientific research base have some defense facilities...

After all, there are indigenous people or other creatures on this planet, and defense facilities are still necessary.

"I just didn't expect it to be so weird."

There was no need for Yu Yifeng to give orders. Several experts immediately took action. They tried to zoom in on the entire captured image to figure out why the entire submarine was broken down into powder.

But it's a pity.

There was nothing in the image... the submarine seemed to be inexplicably disintegrated at that moment.

"Is there some decomposition light? Is it chemical decomposition? I think it is more like physical decomposition..."

Everyone present was thinking hard, and finally Yu Yifeng said decisively: "If it doesn't work, send a few more submarines to test and test the differences in the composition of the seawater in the area...

"If that doesn't work, we will use nuclear bombs. Everyone, please act quickly! We don't have much time!"

In fact, he didn't need to say anything, everyone took action quickly.

But people don't like to use nuclear bombs unless it's absolutely necessary. If everything inside is blown to pieces, people's efforts will be in vain and this precious clue will be wasted.

And Yu Yifeng jumped into the kayak again, trying to communicate with "Ling", and suddenly the little green ball kept beating happily...

In the next half hour, the scientists tried several more times, and each time the submarine was quickly broken down into tiny particles that were difficult to detect with video equipment.

"It's strange that the surrounding seawater lacks certain elements, especially metal elements such as iron and magnesium..."

"The approximate safe range is here... about two meters away from the gate! It will be very dangerous if it gets any closer!"

"There must be something hidden in the sea water, but we can't see it..."

In this situation of constant trying without success, many researchers feel a little tired and their palms and backs are sweaty.

This kind of fatigue was actually caused by a sudden psychological shock, but they were still trying to persevere.

The soldiers are also on high alert, with all kinds of weapons on standby and even the spacecraft in a semi-activated state. If there is any huge risk, they will immediately launch a counterattack.

After a few minutes, the scientists finally discussed several conjectures...

"A nanorobot with the ability to self-replicate is restrained at a distance of about two meters from the gate... Is that so? Is this your guess?" Yu Yifeng looked at Dr. Lan Bo and asked directly: "It has the ability to attack Sexual nanobots...is there any way to crack them?"

Dr. Rimbaud frowned and shook his head slightly: "The defense mechanism of this kind of nanorobot... To be honest, we don't have such dangerous technology. We may need some kind of special signal to avoid their attack."

"I suspect that the signal light that emits red light...or something inside the gate is the control device of the nanorobot! It may take a long time to decipher these signals...and we don't have enough cracking equipment!

"The industry on this planet is too poor and needs enough time..."

"How about blowing up the signal light or the gate?" Yu Yifeng asked.

Lan Bo shook his head in disbelief: "No, it's too dangerous, Captain... This kind of self-replicating nanorobot is a very, very dangerous thing, an absolute 'black shell' level technology!"

"Maybe after blowing up this signal light, they will lose their program constraints. Not only will they not fail, but they will start to replicate endlessly..."

"You know, if the exponential growth continues, after a period of time, there will be more and more nanorobots on this planet, until a certain element is used up... Once it spreads, even us will be very vulnerable. It’s hard to stop this disastrous outcome.”

"...If the signal light blows up, it could be a crisis of annihilation!"

Hearing this, Yu Yifeng frowned.

They had discussed this weapon.

Nanorobots are only at the nanometer level, and their biggest feature is that they can replicate themselves like cells.

But they are much smaller than cells. If there are enough raw materials and energy, nanorobots will grow exponentially with endless replication.

One nanorobot can reach 1024 with 10 divisions and replications, and one million with 20 divisions and replications... Along the way, with endless replications, they will kill almost all living things and decompose everything. Because biological cells also contain elements such as iron and magnesium.

These elements will be forcibly extracted as copy materials.

Without necessary elements, cells will of course die immediately, and the entire organism will look like it has been inexplicably disintegrated.

Nanorobots, world-destroying technology, are 10,000 times more dangerous than nuclear bombs!

Just thinking about it, Yu Yifeng's heartbeat accelerated a few times, and a cold sweat broke out on his back...

Damn, this kind of high-risk weapon is left at the doorstep... Is there something wrong with these damn aliens? !

"Or... find another location to dig in? Do not go through the door, destroy the surrounding walls and enter the laboratory..."

Dr. Rimbaud immediately shook his head: "No! These walls are made of high-strength metal. I don't know how thick they are... Only by bombing with nuclear bombs or high-explosive bombs can they be broken open quickly... It is estimated that a large cutting machine will take a day or two."

"Is there anything Ling can do about this metal that is too hard?"

(The following content is for theft prevention...)

Yu Yifeng shook his head. It would be difficult for "Ling" to use brute force to destroy these walls, because these things are too hard...

The ability of biological cells is powerful, but it is also limited. When facing strong metals, they cannot be swept away with a "bara" like corals. Instead, they have to be dug slowly like mining, corroding and decomposing bit by bit.

But this biological mining speed is not fast...
