The appearance of a city immediately aroused everyone's interest.

But as far as the eye can see, the city is so dilapidated and desolate......

It had been submerged by the sea, with only a few taller skyscrapers showing their heads.

The tallest building, with what resembles a giant sample of tertiary syphilis, covered in red, orange, blue, and purple algae......

In contrast to the ocean full of life, this lifeless city brings an inexplicable sense of heaviness.

The drone is whistling and flying by, transmitting back a large amount of images, and it is difficult for the human eye to get a lot of information from a large number of cameras, but a very fast computer can!

At this moment, the amount of computation on Titan Z and the supercomputer on the Deep Space began to soar. The image recognition function is fully turned on, and as long as an unusual life is photographed in it, it will definitely be able to find out!

"How? Are there any traces of intelligent life found? Xu Yunjin asked anxiously.

A staff member manipulated for a while and shook his head: "It's a pity that after calculation and analysis, the drone has not captured suspicious pictures for the time being." ”

"According to our estimates, this area has been abandoned for decades...... For about twenty years, it's all ordinary marine life. ”

Xu Yunjin frowned, an abandoned city flooded by the sea......

What does it mean?

Many scientists are also analyzing the reasons for the city's abandonment.

Next, the drones naturally divided into several teams, and some of them continued to explore the inland areas. Another team circles the sky above the city, trying to find some useful clues.

They dropped a hexapod on a skyscraper, clinging to the wall and crawling in through the window.

Among them, Yu Yifeng did not issue any orders, but let them go. Overall, he was fairly satisfied with the captains' actions......

"Surprisingly, although the city was submerged by the ocean, it looked fairly intact and showed no signs of attack. There is a bit of nuclear radiation, and it should be radioactive fallout from other places. ”

"You see, the rooms are generally clean, and valuable things have been taken, and it doesn't look like a hasty evacuation. So I think that these natives should retreat in an orderly manner...... They are already anticipating a significant rise in sea levels that will inundate cities...... It's not like an emergency! ”

A scientist studied the images, scrutinizing them carefully.

"It's a pity...... Over the years, many things have been corroded by seawater, and these sea creatures have a high corrosive ability. Not submerged, only a few. ”

From this city, people do not get very effective clues.

In particular, mankind has not even found traces of war...... That's a little weird.

Of course, even if the evacuation site was clean, people still found a lot of discarded garbage.

Among them is e-waste, but also some discarded furniture, books, electrical appliances, and so on. Robots habitually collect them.

In particular, the things in the books are quite useful, and you can find the corresponding words and pictures from them......

"Let's try the translation robot that has been researched in recent years......

"Huh...... What is it? Click on the machine, you can try to fix it, it's a good thing! "Some experts in informatics have already begun to work in advance, and deciphering the texts of indigenous civilizations has become the first major task.

Over the years, the progress of human technology has been all-encompassing, and of course the ability to translate has also been greatly improved. If there is enough information, translating the language of a text should not be too much of a problem.

Looking at the picture on the screen, Yu Yifeng pondered.

A well-submerged, well-submerged...... Could it be that the civilization's rampant use of fossil fuels triggered the greenhouse effect, which then led to a rise in sea levels?

Most likely...... The cities are all submerged, and of course they can't be inhabited.

Also, what exactly are the points of light that were observed in previous years?

Is it really a nuclear bomb?

"More than 10 years have passed since the few points of light observed by the astronomical telescope."

One scientist speculated: "It would take 6.8 years for the light here to reach the metal planet GB131." And we spent another two years digging on the metal planet, and three years of curvature sailing...... In total, it adds up to a little over eleven years. ”

"So...... If there really was a nuclear war, it would have been more than 10 years ago! ”

"It's been more than ten years since the end of the war!"

Hearing this inference, Yu Yifeng nodded silently.

He wanted to give some instructions to the front, but he forcibly endured it. Since they were given enough permissions, they shouldn't be bothered.

He just secretly reminded Xu Yunjin in Titan Z to be more vigilant, because this planet is a little weird.

In fact, the captain of these frigates was more careful than he thought. They didn't give out more drones, nor did they put the robots into fully automatic working mode, still patiently and manually controlled.

Well, even if it's a little slower, everyone can wait......

The first vanguard flew at a fast pace, skimming over the flooded city and heading inland.

Shooting all the way at low altitude, I found some roads flooded with weeds, half-collapsed houses, and messy construction debris......

There are also various iron towers that fall to the ground crookedly, which should be used to pull wires. All of these metals show a lot of rust in their tracks.

It's exactly a ...... Wasteland!

After so many years, the radiation dose still exceeds the normal standard. If you live in such a place for a long time, you will not die immediately, and you are likely to develop certain chronic diseases. This made many people shout in a low voice, this kind of wasteland planet, just to control the radiation pollution, it takes a lot of energy.

After half an hour, the drone finally found traces of the war.

A huge nuclear crater!

A large number of houses in the surrounding area have collapsed, but the various plants in the crater have grown lush green.

Life is always tenacious, and even with radiation, there is still life that can survive tenaciously here.

They have been here for generations, and although their lifespans may have been shortened, they are still alive......

"In terms of yield and nuclear radiation, it should be a hydrogen bomb or a neutron bomb...... The amount of radiation is not large! ”

"It's a pity...... Still no intelligent life has been discovered! ”

Until now, it has been more than three hours of drone exploration, and there are indeed many traces of intelligent civilization, but there are still no living intelligent creatures.

That's a bit of a weirdness......

Yu Yifeng made up from his mind, if he razed Joniu or Jingdong on the earth to the ground, it would seem like this......

In more than ten years, intelligent civilization has inexplicably disappeared, the whole planet has returned to the wilderness, animals have returned to wildness, plants have grown wantonly, and everything seems to have been abandoned for a long time.

What about intelligent life? It's gone. Not only the human eye, but also the computer did not find the slightest discovery!

Are they extinct?

Faced with this scene, Yu Yifeng suddenly had a sudden pain in his temples, and his heart beat faster, an inexplicable discomfort was produced at this moment!

His sixth sense showed that the planet was not in great danger beyond human capabilities, but he always had a strange sense of unease.

And as time passed, this sense of unease began to magnify.

There are many ordinary creatures, and they run happily on the ground, enjoying the return to wild nature. However, according to the analysis of the images, the probability that they have true intelligence is extremely low...... Certainly not the true master of the planet.

Everyone felt a little inexplicable, yes, inexplicable. People searched cautiously for a long time, but did not find the existence of intelligent life, as if these creatures had suddenly evaporated from the planet en masse.

Taken by aliens?

Still is...... The war is dead?

"It doesn't have to be a nuclear war, maybe there's a biological war, like a zombie virus, a T-virus ......," one scientist whispered......
