At seven o'clock in the morning of the second day, he prepared some food and water, and then walked up to the lifting platform, where he set up a water drop aircraft and sat in the driver's seat.

"Didi...... The sun hasn't come out yet, and the butt can't bloom in the sun......"

The AI sang strange lyrics, completely unable to understand what it was doing, Chen Shi frowned, and after it finally finished singing the inexplicable song, the water droplet began to start and slowly rose into the air.

"Remember your mission? Well, didn't answer? You gotta say you know sir...... Really, you don't have a bit of a humorous cell, I'm starting to miss my designer, that's really a man with a strong humor cell, his bad jokes have not been surpassed so far, or I'll tell you a bad joke about him? ”

Without waiting for Chen Shi to object, the AI said to himself, "One day, the toothpick found that its shoelaces had fallen off, so it bent down to tie the shoelaces, and then its waist broke. ”

"Haha, human, isn't that funny?" AI mimics human laughter.

What the hell is this?

Chen Shi was stunned for a long time, and wondered: "The toothpick is bare, where will there be shoelaces?" Can it still wear shoes? ”

The AI's laughter stopped abruptly, and after a while, "Are you really, do you understand this as a joke?" ”

"Aren't bad jokes logical? If it's a joke without logic, it's not funny. ”

Chen Shi said indifferently: "Then I'll tell you a few jokes too, right?" ”

The water droplet automatically controlled the take-off, rose to the top of the cliff, looked in the direction of the east, and began to slowly accelerate and fly away. The whole land, except for the desolate stones, is bare snow-capped mountains.

The acceleration of the aircraft did not affect the speed at which Chen Shi spoke jokes.

"AI is asked by the designer to move the blocks on the table to a specific place, and the solution of AI is...... Move the table. ”

"The designer asked the AI to identify and classify the photos of poisonous mushrooms and non-poisonous mushrooms, but the AI found that the pictures of poisonous mushrooms and non-poisonous mushrooms appeared alternately, so it directly classified them according to this, without learning anything from them."

"The designers asked the AI to run against another AI, so they grew extraordinarily long legs and fell forward and crossed the finish line."

"The designers made sensors for the AI robot to make it accelerate its motion, but it was not allowed to hit something to trigger the sensor, so the AI learned to move backwards because there were no sensors behind the robot."

"Ah, are you mocking me?"

The AI suddenly became angry, "I heard it, don't think I didn't hear it, I'm not comparable to those stupid AIs, but fortunately, I won't be angry, I will forgive you for your offense, after all, the lifespan of human beings is only a hundred years, I will wait for you to die and then come back to revenge you, such as scattering your ashes in the sewer." ”

Chen Shi sneered, casually scolding this AI, the two confronted each other, and they both felt that they were not left behind.

Four hours later.

Near eleven o'clock in the morning.

The water drop drone had already carried him forward for more than 2,000 kilometers and was approaching his destination.

Breaking through the gloomy clouds, the aircraft began to descend to about two thousand meters. At this altitude, the droplet is large enough to bring the entire land into scouting range, and zoom to the point where it can read the handwriting on newspapers.

As long as there are signs of human activity, there is no escape from the detection of the droplet.

Chen Shi was silent.

Ten years ago, he was just walking around that city, but it wasn't enough to be sure if the end of the world was real, and the scope of a city was too small to show that the whole world had become like this.

But at this time, after a journey of more than 2,000 kilometers, he overlooked the land and saw countless desolate cities and vast saline-alkali land...... Of course, not to mention that all of them are surrounded by saline land, there are also many temperate meadows.

The temperature is kept around -10° to 11°, and humans can still adapt, but after there are no animals, there is no environment for planting, and where can there be any food output from this desolate land?

To be honest, Chen Shi really doesn't understand, how should those humans who pop up survive?

Maybe they will blame themselves?

After all, it was their own fault that brought them out of their dormant state, so that they could pop off the ground and have to face such a nightmare.

But it can go on like this, and sleep endlessly...... Until one day in the future, even the machine can not be loaded, and it will not pop up again if it fails?

Ahead and late, they must face such a fate, and they can't always run away from it.

Chen Shi didn't feel much guilty, and it was impossible for him to give up taking out the cube because of this.

He's going home...... The fate of eight billion human beings is still in his hands.

Time does not wait for him.

But...... Is it true that the celestial AI is saying?

It was hard for Chen Shi to believe that there would still be human beings alive when the material conditions were so scarce. You can't let people eat grass, right?

Then there is only one possibility.

They may have scavenged for food from desolate cities......

Chen Shi looked up in the distance, at the end of the skyline, there happened to be a city.

This is also the place where the AI found the traces of the human remnants, which is in line with Chen Shi's speculation that the remnants should live not far from the city.

Think back to last night.

Chen Shi asked a crucial question, how did the end of the world happen? Where does the reason come from?

Celestial AI did not keep silent this time, but projected all the video materials to Chen Shi.

The so-called end of the world, mankind has long guessed many ways.

In general, there are two types.

One is the human factor, such as nuclear war, biochemical warfare, global epidemics, and so on.

The second is natural factors, such as meteorite impacts on the earth, reversal of the magnetic field at the north and south poles, disappearance of the magnetic field, internal changes in the sun, orbital deviation of the solar system, gamma-ray bursts in the center of the earth, etc......

If the former can be avoided, then the natural disasters of the latter are powerless for human beings.

Sometimes, with bad luck, a single meteorite can wipe out human civilization completely.

So natural disasters are very common in the universe, and it is not incomprehensible for a strong solar storm of instability on the stars to make civilization retreat.

But the world ...... The end of the world is not one of the above speculations.

It wasn't a nuclear war, not even a war, and most cities weren't affected by the war. It's not an epidemic either.

It has nothing to do with human internal factors.

But it's not caused by some known natural disaster, eh...... The desolate land of the earth today is actually formed by human beings themselves absorbing natural resources too much, and has nothing to do with the end of the world.
