Nanotechnology

"Perhaps, I should have turned around and left as soon as I discovered the anomaly on this planet," Yue Yuan thought to himself, glancing at Man Yuemei standing to his right.

After the Silver Mist completely obliterated the human landing site, Yue Yuan noticed that even the perpetually icy-faced Man Yuemei changed color.

This was the first time Yue Yuan had ever seen her like this.

"Chief of Staff, where's the satellite?" Yu Nanfeng asked.

"Let's stay here and continue observing the Ross 154-4 Planet. We don't know if that Silver Mist has the ability to fly out of the planet. It's always good to keep an eye on it. If... I hope there are no ifs." Yue Yuan leaned back in his chair, gazing at the dome of the Command Center.

Yue Yuan leans towards the idea that the 'Silver Mist' doesn't have the ability to fly into space; otherwise, they wouldn't have stayed on the planet all this time. If they really had the ability to come out, then humanity would be in real danger.

Just then, a staff member sitting at the control panel in the Command Center suddenly exclaimed, "Look, they're moving again!"

That loud shout almost scared the people inside to death.

Everyone immediately stared wide-eyed at the big screen, fearing that these things might rush into space.

At this moment, the large screen had been switched to several split screens. On the split screens, people saw that the clumps of Silver Mist that had been lying on the metal mountain had slowly floated up again, and then merged into a large clump again in a certain place.

Immediately afterwards, the fog drifted away in a certain direction like locusts.

Seeing this, everyone secretly breathed a sigh of relief.

Thankfully they didn't come up, otherwise humanity really wouldn't know what to do.

"Look, they've stopped."

The screen was magnified again and again, and everyone saw that the Silver Mist, dyed red by the starlight, made a turn in mid-air and fell to the ground like a swarm of locusts, scattering into a red mass and quietly sticking to the ground without moving.

From satellite images, it looks like a patch of seaweed shimmering with a dark red light. The AI quickly calculated that it covered an area of 200,000 square kilometers.

"Such a large area, how come we didn't discover it before?" someone muttered, seemingly complaining about the lack of exploration.

"No, they weren't originally here." A staff member said, pulling up the original satellite image for comparison and showing it to everyone.

As expected, the two pictures are identical except for the ground where the Silver Mist is currently located.

In other words, the Silver Mist wasn't originally here; it appeared out of nowhere after humans landed.

After watching for a while, Yu Nanfeng once again expressed his opinion. He fiddled with the control panel and then turned the swivel chair around. "They should have come out of some cave, but that cave just happens to be outside the coverage area of our satellite. In their current state, I think they are absorbing solar energy. Oh, I mean Stellar Energy."

"Is it possible that some kind of organism is photosynthesizing right now?" a voice asked.

"We cannot rule out this possibility, but judging from the data we have obtained, this possibility is very small. They are most likely creations of some Alien Civilization, which are the mining tools I mentioned earlier."

Yu Nanfeng shook his head and continued, "If I'm not mistaken, they were probably dormant in some cave before. Our landing disturbed them, perhaps through our mechanical signals, Electromagnetic Wave, or even our life signals."

"Life signal?"

"Yes, life signals, such as brainwaves, may sound absurd, but we cannot judge the creations of Cosmic Civilizations based on our current level of technology. Just because we cannot detect them does not mean that other Cosmic Civilizations cannot detect them either."

Seeing that everyone was nodding, seemingly accepting his statement, Yu Nanfeng continued, "If the guess that the Silver Mist is a miner is correct, then they must have some kind of program. It's not hard to see from its behavior that this program must be one that collects and separates minerals."

From this perspective, their creators have indeed left this place long ago, just as we previously suspected. We don't know why they didn't return after leaving. Perhaps that civilization forgot about them, or perhaps for that civilization, the Silver Mist was merely a mining tool that could be discarded at any time. Of course, we cannot rule out the possibility that that civilization encountered some kind of unforeseen event.

"In other words, the 'Silver Mist' mining tool is most likely just operating according to a program pre-programmed by its creators, and it may be mistaking our transport ships and all the alloys for minerals."

"You mean we were crushed by the mining tools of some advanced civilization? And we don't even know what those mining tools are?" a researcher asked incredulously.

"Yes!" Yu Nanfeng's tone was filled with resentment and helplessness. "They are not even weapons, but merely mining tools."

A single mining tool has rendered humanity helpless, leaving them without even the courage to launch another Unmanned Ground Probe.

Yu Nanfeng stood up and continued his analysis while pacing back and forth, "However, it also means that we have no idea what they are exactly. Based on the data we have observed and the various characteristics and functions of the 'Silver Mist,' I think that the so-called 'Silver Mist' should be a kind of Nanobots."

"Nanobots?" everyone exclaimed.

The term Nanobots is not unfamiliar to humankind. As early as the 21st century, cutting-edge medical fields began research in this area and have already developed them.

Scientists created tiny Nanobots mimicking the shape of E. coli, then injected them into specific areas via a 2-millimeter catheter. Afterward, they used an externally generated magnetic field to guide these microrobots, enabling them to move within the body to the lesion site for testing.

These Nanobots move in the same way as E. coli, using a spiral 'flagellate' to propel themselves.

There is still much research to be done in this field.

For example, in 2022, a lipid nanoparticle composed of G0-C14, PLGA and Lipid PEG was developed and modified with CTCE-9908, a specific targeting peptide for CXCR4 that is highly expressed in liver cancer cells, thereby achieving specific targeting of liver cancer cells.

Using this novel lipid nanoparticle delivery carrier, p53 mRNA was specifically delivered to liver cancer cells. When combined with Anti-PD-1 Monoclonal Antibody, it effectively induced global reprogramming of the Tumor Microenvironment (TME), thereby achieving better anti-tumor effects.

In addition, scientists have developed miniature swimming devices or miniature robots for precise in vivo drug delivery, as well as research on artificially manufactured protein nanocages and the use of chiral gold nanoparticles to enhance immune responses, among other things.
