Three days later, a block away, behind a makeshift defensive line, a cyclist, carrying a black package, approached at a rapid pace and stopped ten meters before the fence.

He parked his bike to the side and stood there with his hands outstretched.

Not far away, there was a scan, the light swept from left to right, from top to bottom, and the sign at the gate that prohibited traffic turned green.

At this time, he slowly walked out of the quarantine area.

There was already a group of officers waiting inside, and when he returned, a high-ranking official wearing a police uniform and carrying a flower on his shoulder asked loudly: "How is it, have you taken a sample?" ”

"Yes sir, this time it went well!"

Everyone was overjoyed, and hurriedly took the black package he handed over and quickly sent it to the temporary laboratory.

In the laboratory, there were already a few scientists waiting there, and when they received the black package, they drove everyone out as soon as they could open it.

Then a signal isolation device is added to the outside to close the laboratory.

Officials were invited to another tent, where they could see the inside of the lab on a large screen.

In the monitor, the scientists looked a little excited, and while carefully opening the black package and taking out the special cylindrical container inside, they casually explained: "After the third improvement, it can be basically determined that the mechanical spider has a relatively low degree of eating quartz, and has slowed down the pace of self-replication in the isolated signal state of the black box." It is preliminarily determined that the next step of the experiment can be carried out......"

The senior police officer slapped his palms excitedly and said loudly: "Sure enough, it worked!" For the first time, I drove a military vehicle to get a sample, and the whole army was wiped out, and only a few slick soldiers escaped. The second time, an inorganic colloidal protective suit was specially made, but it was still broken down by the mechanical spider, and the culture flask of the sample was not spared.

This time, we used clothes and materials made of pure bamboo charcoal fiber, and we used a simple bait-catching automatic recycling device, and we succeeded once! Tell me to immediately form a squad and follow this method to obtain as many mechanical spider samples as possible. ”

"Yes, sir!" At the sound of the order, someone behind him immediately took the order and left.

None of them looked back, their eyes still glued to the monitor.

The current situation is very troublesome, and the sudden influx of liquid metal, and the mechanical spiders that have changed in the later stages and can eat metal and other substances to replicate themselves, are completely unknown.

In the area covered by the mechanical spider, the signal is completely disordered, and the remote scan seems to be non-out-of-order signal interference, and it is completely ineffective. And singing too closely, it will cause the mechanical spider to spontaneously counterattack, and a wave will rush over, directly and instantly stripped off.

Such a public and shameful move is really unacceptable to ordinary people.

Fortunately, in any case, the mechanical spider has not hurt anyone, which is already rare good news.

The scientists carefully took out the inner tank, only to see that there was still a thin lead film under the glass shell, and opened the plug with bamboo tweezers, and carefully took out a mechanical spider.

A mechanical spider the size of a grain of rice jumped twice in the petri dish, and suddenly melted into a puddle of metallic liquid, sticking to the petri dish like soup dropped from a meal.

The scientist's eyes widened and he said with some excitement: "There is still the ability to change the state, and the third route is selected for the 12th experiment." ”

As he spoke, he picked up the petri dish, slowly poured the liquid metal into another petri dish, made a simple thin slice with a straw, and quickly stuffed it into the experimental equipment.

The computer was speeding up, and the assistant next to him reported: "Otherwise, the quartz that is not easy to gas is compared to 1/3 of the corroded, according to the personal video provided by the police in front, it is roughly estimated that the volume of liquid metal should be doubled." ”

This is another assistant, holding the Petri dish he had just used, and said: "The bottom of the Petri dish is in a state of corrosion, the oxide layer is corroded, and the glass is corroded by 1/10. ”

The scientist nodded, but did not speak.

Everyone's eyes were fixed on the display of the instrument, including the high-ranking officials standing in another tent.

Soon a picture appeared on the monitor, the scan line from top to bottom, from left to right, the picture gradually became clear, the subtle light points automatically zoomed in, and a small octopus-like object appeared.

Its head is slightly pointed, and the whole is in a 16-sided diamond-shaped state, with eight tentacles in the lower half.

This is not terrifying, what is terrifying is that its eight tentacles are forming entities at a speed visible to the naked eye, as if liquid is poured, and soon another tip of the 16-sided diamond-shaped state is formed.

After that, the whole particle begins to elongate and gradually splits into two.

The scientist exclaimed, "Self-replication, nano-replication, oh my God, this is incredible!" ”

Another scientist's lips trembled: "Nanotechnology with a very high degree of integrity, which represents a great leap in the level of human science, aerospace materials will explode, if the energy system keeps up, we will touch the edge of space in just 20 years." Oh my God, this is a generational invention! ”

"Not only that, if you can master this technology, you can completely achieve immortality in another state, and this kind of nano-level small robot with its own program can form another invincible immune system in the body......"

Several scientists were so excited that they explained for a long time, and the officials had already been impatient to listen to it, and hurriedly shouted through the microphone: "Gentlemen, calm down, this is not an academic discussion, but a battle against time on the battlefield." Unknown liquid metals are eating away at our land, they are so fast that they can devour almost anything, and our existing armed systems are completely powerless against this unknown object, if you can't find an effective way. The government may issue an evacuation order to destroy the neighborhood within 24 hours. ”

Several scientists were stunned and asked, "You want to use a nuclear bomb?" ”

"I don't want to admit it, but I'm afraid it is. Arms experts have preliminarily confirmed that the small explosion is completely incapable of causing damage to these mechanical spiders. We tried to project small missiles, only to be rewarded with an explosion of mechanical spiders, and military experts suspect that these strange liquid metals can absorb the energy generated by the explosion to some extent and use it to replicate itself.

And the only way is to increase the power of the explosion, so, hurry up, gentlemen, you have less than two hours now, or New Greenwich will be in a state of evacuation......"

A scientist retorted: "These mechanical spiders obviously don't hurt people, why don't you send people into the burrow to explore and know its source......"

Before he could finish speaking, he was interrupted.

The senior police officer said unceremoniously: "Five squads have been dispatched, a total of 60 people, and it has been more than ten hours now, and there is still no news, and we have reason to suspect that they have been killed......

He didn't finish his sentence, but everyone understood what he meant.

The scientists looked at each other, understood in their hearts, and did not say anything more, focusing on the experiment.

They also want to find a way to explore the unknown and wonderful phenomena as soon as possible.

Rather than officials anxious to solve the problem, they want to solve the secrets of nanomachinery as soon as possible, which is an unknown science.

For scientists, there is nothing more appealing than this!
