I run a food city in the last days

In the end, of course, the decision was made to open it, but the top management of the flower grower made sufficient preparations and used the underground safe house that had been secretly built to prepare for nuclear war as the location to unpack the packages. Then a group of skilled workers worked overtime to install machinery in the safe house. Arms and various cameras ensure that the entire process of unpacking the package is under the full observation of the bosses without requiring them to get even half a step closer.

When everything was ready, the all-terrain autonomous transport robot delivered the package to the safe house and placed it in the middle of the floor of the square room.

Then the robot pushed away, and the safe house automatically closed and locked, activating the highest level of security protection.

It is no exaggeration to say that as long as the earth does not disintegrate, the house will remain unscathed, and any changes inside and outside will not affect the other side.

However, everyone is still a little worried. This comes from a higher-level civilization that is inaccessible to the high-level alliances in the universe. If it is really lethal, it may not be able to stop it with the existing methods on earth.

But the earth is just a seedling that has just revealed its sharp corners. Is there really a high-level alien civilization that would spend so much effort just to destroy them?

The robotic arm is activated, and the robotic arm, which is no different from human hands, flexibly uses the thumb and index finger of both hands to lightly open the outer layer of the package.

Inside is something that no one has seen but is obviously used to prevent shocks, indicating that the items in the package are afraid of vibrations.

Either it is more fragile, or the vibrations would be dangerous.

The robotic arm began to dismantle the shock-proof items outside. The bosses who observed the situation from a distance through the 360-degree high-definition camera with no blind spots couldn't help but feel a little excited.

Finally, the shockproof layer was removed, revealing what was inside.

?

Everyone looked at each other, so what were those two pieces lying quietly in the earthquake-proof layer?

Rectangular, it looks very thin when viewed from the side. When viewed from the top, it’s hard not to think... But it’s impossible. How could it be that thing that was sent all the way across two levels of civilization?

No one spoke, and no one wanted to tell his guess first. The main reason was that it was too impossible. There must be something profound that he hadn't discovered yet. It would be too frivolous to say the answer casually now.

So the cosmic express was finally dismantled, but the expressions of the big guys outside the camera became more serious. Their sharp eyes kept moving in the pictures provided by different lenses, trying to find any clues to confirm what it was.

Time passed by, everyone remained silent, and the atmosphere became more and more dull.

Seeing that the whole day was about to pass, everyone finally felt that continuing like this was not an option. Someone whispered, "It's better to bring the things over and check them."

Others nodded. At least after almost a whole day of observation, those two things didn't look dangerous.

However, for the sake of safety, everyone decided to use an unmanned research institute to conduct preliminary research.

The robot took the two pieces out of the safe house. Since it was tightly wrapped with anti-shock materials before, this time the bosses chose to use the highest-level delivery robot, which can ensure smooth and safe delivery even in the hail of bullets. Fragile goods.

The two items were safely delivered to the unmanned research institute. The so-called unmanned research institute is actually a research location that combines automation and remoteness. Both of these can ensure that researchers do not have to risk their lives in high-risk or contaminated experiments.

Of course, some experiments require high precision, so researchers still have to do it in person, but reducing the number of contacts also protects their health in disguise, so the existence of unmanned research institutes is still necessary.

This is also the case now. Everyone has begun to remotely control the machinery of the institute and cooperate with automated robots to study these two things.

However, the more I studied, the more the "unbelievable" answer became noisy in my mind.

It's really - too similar.

Finally, an older researcher said in a deep voice: "Everyone, I have to say, I really can't come up with a second answer after seeing this thing." He glanced at the people around him, "These are just two tablets. , it’s still the same style as it was decades ago!”

That’s right, since seeing these two things, the answer “tablet” has popped into everyone’s mind.

But unlike the tablets they use now, this was a tablet from 20 to 30 years ago that needed to be charged and had a certain weight in the hand.

"...So a high-level civilization, traveling thousands of miles away, sent us two outdated tablets?" Someone answered with difficulty, feeling that every word he spat out was violating his professional ethics and was completely illogical. Sex is so unconstrained that it makes him ashamed.

"Look here," the older researcher manipulated the robot hand to point the side of one of the "tablets" at the camera, "power button, volume button."

Scroll through again: "Audio, speakers, charging port..."

Someone has already recreated the style of tablets from thirty years ago. It has to be said that these two things really look alike. Except that there are no brand logos on the back of these two tablets from the universe, no one can unscrupulously say that they look similar. It doesn't look like it.

Silence enveloped everyone again, and after a while someone finally spoke tentatively: "I remember that tablets in the past were powered on by long-pressing the power button, right?"

...Okay, no matter how hard you try, you can't get the answer "tablet" out of your mind, so you might as well treat it as a real tablet.

The older researcher operated the robotic arm and extended his index finger to the power button. He also made a cold joke: "This thing is out of power. I don't know if I can still find such an old model charging cable."

However, it turns out that it is a cosmic tablet with an extraordinary origin after all. Its standby time is the longest among all the others. Three seconds after the power button is pressed, the tablet lights up.

No one showed any expressions of surprise. After all, their brains had already accepted the conclusion that "this is just a tablet." It was surprising that it didn't light up.

Next came a boot animation, and everyone even heard an ancient boot ringtone.

Okay, now they feel more and more confused. Are they really studying something taken out of a cosmic package, rather than conducting some antique research?

After about five seconds, the startup screen disappeared, and everyone looked at the "desktop" of the tablet.

Finally something different appeared. There was nothing fancy on the desktop. The background was a deep starry sky. There was only a small, round icon in the upper left corner that looked familiar.

The older researcher looked at it for a long time and said, "This seems to be a sign of a camera, right?"
