It was an amazing trip. The temperature can be felt in the soil, and apart from those annoying consciousnesses, it should not have awakened yet, and it is not known what creatures were born during the ice age of prehistoric civilizations.

More than 100 meters of soil were quickly penetrated, followed by several meters of inorganic protection. The precipitation instrument that you carry with you can easily analyze the composition of this inorganic substance, which is an element that has not been seen in modern times, but it was prevalent in prehistoric civilizations. It's fragile.

Zhou Kun couldn't help but sigh.

It took a little time to walk through this inorganic substance relative to the soil layer, and then it seemed to ...... Zhou Kun, who had just broken away from the inorganic layer, felt that his body had fallen directly, which was an inorganic protective cover similar to the transparent metal cover of a modern city.

Remains of a prehistoric civilization!

In the process of falling, Zhou Kun adjusted his posture and suddenly found that there was a large city below. These are the remnants of a legendary prehistoric civilization!

Zhou Kun shouted wildly in the channel, and the situation on the scene was directly transmitted to the channel sharing.

There is no sunlight, but there is very little light.

It's an exaggeration, but these buildings are clearly different from modern ones, both in terms of materials and styles. After using the jet a few times, Zhou Kun slowly landed on the top of the tallest building in this prehistoric city.

The moment they landed, the entire city sounded in unison with a uniform siren, "Intruder found, intruder found." ”

Zhou Kun was dizzy for a while, could it be that there are still people in the city? How can it be? In order to confirm, Zhou Kun almost laid two life detectors on the roof of the building at the fastest speed, and then left in a hurry without looking back.

Just a dozen minutes later, several figures appeared on the roof of the building.

However, the three-dimensional watch in Zhou Kun's hand did not have any hints.

Zhou Kun is hiding in the corner of the city, damn it, how can there be people in the city? The exoskeleton suits show that the air pressure and atmospheric oxygen content of cities are almost the same as those of modern cities, only slightly lower.

Where there's water, there's air, there's life? Zhou Kun was a little skeptical about life, how long had it been, or was there still someone left behind when he was evacuated?

Moving from one corner to another, Zhou Kun gradually became familiar with the environment of the city, and the best way to understand the truth, I am afraid that there is no best way now. Although there are not many of them, the whole city seems to be hunting itself.

Is it to explain? Zhou Kun instantly rejected the idea, explaining that it might not be useful, he didn't want to take such a senseless risk. These people are clearly divided, obviously professionally trained, and should be soldiers, at least inspectors.

The destination must be determined as soon as possible, and then detached. Soon, through the locator, Zhou Kun confirmed the library and administrative center. The library can collect a lot of important information, and the administrative center can confirm whether the city is being effectively managed.

These buildings have been somewhat weathered, although they look special, but the color is too simple, Zhou Kun thinks it is strange, why not use metal?

One mystery after another lingered in Zhou Kun's mind. Zhou Kun regretted a little, could it be that the life forms detected in the basin refer to these? Truly incredible.

The library is in the east of the city, next to the administrative center, and there are large parks in front and behind, and Zhou Kun didn't see anyone else along the way except for those who chased him. In a dodge, Zhou Kun suddenly hit a big tree, and the big tree actually fell, what the hell is this? Zhou Kun was startled, and after making sure that there was no one around, Zhou Kun leaned over to look at it, which ...... It's not a tree at all, isn't it a tree all over the city?

I grabbed a handful of tree trunks, this, the material of this tree.

A flash of fear flashed through my heart. Gotta get out of here.

After several turns, Zhou Kun took refuge in a campus that was still 2 kilometers away from the library. Zhou Kun took out the remnants of the tree trunk that he was grasping in his hand, this is a strange material, it can be determined that it is a non-living object, but he can feel the extremely sensitive meridians that exist in this object, what is this? Zhou Kun thought about everything he could come up with, and he couldn't describe this thing.

The sirens sounded louder nearby, and they seemed to stop where they had just been. Zhou Kun felt that his breathing was a little short, and he tried to calm himself down. What's going on with these people? Could it be aliens?

This is impossible, how can the Martian colony, the lunar base, the space station, and so many surveillance systems be missed. These people look like they're human, but why doesn't the instrument show life forms?

The sirens faded away. Zhou Kun got up after taking a short break, and walked through this school, which should not be far from the library. Zhou Kun leaned against the wall to move forward, the school was empty, and occasionally you could see the textbooks scattered on the ground, Zhou Kun wanted to take a copy back to study it, but he didn't expect that as soon as he touched the textbook with his hand, the textbook turned into powder.

The textbook should be fine, Zhou Kun said in his heart.

------------------

At the other end of the channel sharing, Yu Bujing, Zuo Lan, Xu Suyu, and Liu Shujuan saw every scene that happened, and each pinched a cold sweat for Zhou Kun.

"Are there terrestrial people underneath this earth?" Xu Suyu, who has a little research on prehistoric civilization, asked.

Zuo Lan shook his head, "Unlikely." What's more, Zhou Kun himself did not confirm it. ”

I really couldn't explain it, I didn't speak, I turned my head to look at Liu Shujuan, "I can only be in a hurry, I can't save it, what should I do?" ”

"Don't worry. The captain's equipment was quite good, and we went only to drag. Not to mention that you can't go. The best thing to do is to return to Galileo right away, ready to move. I guess the captain will definitely find a way to get rid of these people and come back. Liu Shujuan's judgment sounded like there was no problem, and she could only slowly retreat to the Galileo.

"Can you reconfirm how many lifeforms there are in the city?" Zuo Lan asked.

"You can give it a try."

Soon, the vital tester showed that there was no living life in the city.

Several people looked at each other, and the uneasiness and nervousness could be seen in each other's eyes.

"Could it be something chasing the captain?"

"Not a human ......"

-------------------------

Finally, Zhou Kun hid in the library, and his physical exertion at the moment was unusually large. Fortunately, the pursuers lost his trace for the time being.

Zhou Kun straightened his clothes and regained his strength with the help of exoskeleton protective clothing. After that, Zhou Kun set up life testers in the four corners of the library, and the results showed that there were no life forms around.

On the top floor of the library, a human dressed as a woman is looking up something.
