In the midst of everyone's discussions and quarrels, time passed day by day. The Ministry of Security did not find any anomalies in the surveillance, and no extraterrestrial life came out of it to trigger a nuclear bomb to wash the ground......

All these circumstances gave a sigh of relief to all the cautious people.

After two weeks, humanity finally couldn't take it anymore, and it didn't seem like there was any point in waiting, and the first exploration operation officially began!

On this day, many people gathered in the captain's room, staring nervously at the surveillance screen.

An unmanned car is on its way to an alien flying saucer, with a dozen modified spider robots inside.

They were originally murder weapons in the army, the size of a basketball, eight metal legs, and agile movement, but at this time, the barrel in their mouths and the ammunition in the abdominal cavity were removed, and they were replaced by larger lithium batteries, signal receivers, high-definition cameras and other detection devices. With this modification, it was a good fit to be in charge of this exploration activity.

Scientists have high hopes for the dozen or so spider robots, hoping that they will complete the initial exploration of flying saucers and rule out some dangerous things.

“…… This kind of robot is not as good as humans, it is too small, and when it encounters something sudden, it can't be solved at all! ”

Professor Ding Yidong, who was sitting on the side, said dissatisfiedly that although he didn't make this robot, he still criticized it unceremoniously.

Several scientists in the surrounding area are also whispering, discussing the shortcomings of the robot and the success rate of this expedition......

Half an hour later, the car finally came to the flying saucer.

Yu Yifeng looked at all the scientists and soldiers, and said in a deep voice: "Okay, everyone knows, the early exploration work was completed by these spider robots. The entire exploration mission is divided into the following parts. ”

"First, obtain some metal alloy fragments of different sizes and bring them back to the Noah for technical analysis."

The robot had searched the outer environment of the flying saucer, but had not found any metal fragments. According to the analysis of experts in materials science, these metal materials may be like bulletproof glass, which will still stick together after shattering, so there are not many fragments that burst out...... Therefore, people plan to look for this alloy in the flying saucer.

When the scientists heard Yu Yifeng's words, their expressions began to get excited, as long as they found some metal fragments, they were likely to bring new inspiration to materials science!

Human material science is still weak, and the benefits of new materials to human beings are obvious, whether it is a spaceship, a variety of weapons, or a spacesuit, all need the support of new materials.

"Second, confirm whether the defense mechanisms inside the flying saucer are effective. Whether it's kinetic weapons, laser weapons, Gauss cannons, etc., try to draw out any attacks it may have......"

"Third, collect first-hand information from the spacecraft to find out if extraterrestrial life still exists......"

Yu Yifeng thought about it and found that there was nothing to add, and finally gave the order: "The operation begins!" ”

One by one, spider robots crawled out of the car and moved quickly in the direction of the alien flying saucer. This kind of exploration is more complicated and cannot be done by intelligent programs, so it is still controlled remotely by some engineers, and people can get a first-hand view of the robot at the Noah base

This may be the first time that humanity has officially come into contact with an extraterrestrial civilization, and the engineers in charge of the operation are generally nervous. However, their hands were still steady, and the robot found a small hole under remote control and squeezed into it.

One, two, three...... There are a total of twelve spider bots, each with their own duties.

Inside, there was a silvery-white metal corridor, full of potholes and warped metal, which looked badly broken and covered in a lot of dust. Similar to what materials scientists have speculated, many of the metals are broken but still stuck together, and small fragments are barely visible.

Because the dust in the spaceship was stirred up by the spider robot, and it flew all over the sky.

"The impact of the flying saucer when it crashed was too great, which led to the tattered appearance it is now." One scientist explained: "But it's good, at least you can see a rough outline." If our plane falls from a high altitude, in a few million years, we will not even have scum left......"

"These alloys are very hard!" A mechanical engineer controls a spider robot and scrapes the ground with his metal legs a few times, making a "creaking" sound, but leaving no scratches.

"Will this work?" Xu Yunjin asked on the side, "So you can trigger the flying saucer's defense mechanism?" ”

Yu Yifeng shook his head, picked up the cup and took a sip of water: "At the beginning of the exploration, we couldn't directly take people on adventures, so we assigned these spider robots. ”

"The key problem is that we don't know the technological level of this alien flying saucer, maybe only a few hundred years ahead of us, or tens of thousands of years ahead of us. No one knows if there are any defenses inside, they may have been disabled with the crash of the flying saucer, but some of them may still be effective......"

"Whether it's a laser or a Gauss cannon, once it hits a person, it will hang up immediately, and we can't take this risk. So the robot must check first. ”

"For example, this kind of test is a bit like fishing now...... We don't know if there are any fish in the pond, if there are deep-sea giant sharks, so we can only test them with all the bait. ”

Looking at the thoughtful looks of many people, Yu Yifeng pointed to the screen and said: "There are so many spider robots, don't look similar, they are actually different kinds." The devices inside each robot are different. ”

"Some can produce thick smoke and emit high temperatures of several hundred degrees, some can breathe fire, some have a certain amount of radiation, and some can generate strong currents...... If there were aliens inside, you wouldn't have guessed that we would suddenly wreak havoc! ”

"Let me ask you, what do you think would happen if a flame suddenly appeared in the Noah's living quarters?"

Xu Yunjin paused and said directly: "Our safety feedback mechanism will be activated immediately, the alarm will sound, and the automatic fire extinguishing device will be turned on...... And the water will squirt out! ”

"Yes, the same thing." Yu Yifeng took another sip of water and swallowed it. "We all have feedback mechanisms like this on our spacecraft, and alien flying saucers theoretically have them as well. Unless their technology is not at all afraid of unexpected disasters such as fire and electricity leakage, but this should be very unlikely......"

Xu Yunjin nodded, and even many parliamentarians behind him nodded in agreement.

"What's more, it's hard to turn off this feedback mechanism." Yu Yifeng continued: "Like our spaceship, the fire alarm is on all year round. It consumes very little power, and there is no need to turn it off at all. ”

"If you really want to turn off the fire alarm, it is very troublesome, and it requires the approval of a large number of authorities such as the security department and the power department. It is impossible for just an ordinary person to turn off the alarm. ”

Xu Yunjin was stunned for a moment, it was indeed like this, their fire alarm, even he couldn't turn it off.

"According to this reasoning, the flying saucer should have a similar safety feedback mechanism inside, and it is more difficult to turn it off...... In other words, as long as there is no such security feedback mechanism in it, the probability of the emergence of weapon systems is relatively low, because weapon systems tend to be more complex and require more energy! ”
