The cosmic vacuum is cold and dead, for the low-energy universe mentioned by the information bridge, although Cheng Shi can't intuitively feel what kind of miserable world it is.

But after many space flights, he can also vaguely feel the difference in this universe, there is no bright galaxy that is common in the main universe here, and there are not even a few bright stars in the surrounding space, but more light spots that appear from time to time.

And when he saw the extinguished star, the points of light in his mind were the dying sun.

Maybe when he sees the stars in the main universe again in the future, it will give him a new feeling: this is a vibrant universe, civilizations at different stages of development are distributed in various star systems, and some civilizations have just started slash-and-burn farming, and they are struggling to establish a stable residence; And some civilizations are trying to get rid of the gravitational pull of the planet; There are also civilizations that have marched into the sea of stars and are busy fighting for the resources of the universe.

The Kate Eagle landed on the planet where the remains of civilization buildings existed, and after the group put on life jackets, they stepped off the spaceship and began to explore the ruins of this advanced civilization that has been abandoned for an unknown amount of time.

After the five of them stepped off the ship, the Kate Eagle flew into the air and turned on all the lights to act as an artificial sun.

Since sound could not be transmitted in a vacuum, the Bridge also deliberately set up a temporary communication channel that they had only used on the battlefield before.

The spaceship landed in the same place as a large city, surrounded by many towers, some of which even faintly pointed roofs, and other intricate architectural structures, make people imagine that the humans here also had superb construction craftsmanship and a glorious civilization.

Compared to those buildings that look relatively intact, there are more collapsed and cracked houses around. Perhaps time has smoothed out all the edges and corners of these buildings, and everything as far as the eye can see seems to have been poured in one piece, giving it a strange smooth appearance.

Walking among the wreckage of these buildings of unprecedented scale, the cold, dead, and eerie atmosphere around them spreads over them, and a real sense of apocalypse arises.

"Landlord, why are there so many dark crystals here? And these dark crystals, do you look familiar? Yang Yang picked up two black crystals and asked Cheng Shi curiously while colliding with each other and listening to the sound in his ears.

Cheng Shi glanced at the big bird that didn't use his brain: "Don't touch it, you can't hear the sound, the vacuum environment on the surface of this planet is more vacuum than our space over there, don't you know that sound can't be transmitted in a vacuum?" ”

Yang Yang sighed, and threw away the crystal stone in his hand: "But these black crystals look really familiar." ”

Cheng Shi nodded: "Yes, we have seen similar black crystals on the Mermaid Planet and Tanamu Fortress, this is a high-level civilization living on the land of the planet, and their planet may have been reset, so we can study it as a sample." ”

The group came to a hill made of collapsed buildings, where they could vaguely see the city roads leading in all directions, and a small square not far away.

"Little Bridge, check out the era when the city was abandoned." Cheng Shi said in the communication channel.

"Judging from the results of the current inspection of this ship, the nearest man-made object here is about 8,000 years ago, and the sun of this galaxy has been extinguished, this ship has been detecting thousands of meters below the planet, no life has been found, not even organic matter has been found, and its core has been cooled for many years, this ship feels that the owner can treat this planet as a fossil of civilization, and increase the understanding of this cosmic fragment by studying it." The information bridge replied fifteen-ten.

There is no atmosphere, and there is none

With the protection of the magnetic field, more than 8,000 years is enough to make the animals and plants that once existed on this planet not even have bones left, but there are many buildings standing here, which can't help but make Cheng Shi feel a little incredible.

"Let's go inside the tallest building in front of us." Cheng Shi waved at everyone and said.

The group walked along what looked like the main road of the city, and after a few turns, they came to the tall minaret, and soon found a place that looked like a door.

"Yangyang, come here and break the door." Cheng Shi said and waved at the big bird.

"Okay!" Yang Yang first agreed very happily, but in a blink of an eye he began to mutter, "Why do you always let me break doors and smash things?" ”

Oldman saw that Yangyang was unhappy, so he stepped forward: "Why don't you let me come." After saying that, he picked up a fist that was many times bigger than a sandbag and smashed it towards the door.

Everyone looked at the giant's strong posture, although they couldn't hear the sound in the vacuum, but the people around seemed to hear a loud bang, but the door didn't open, and one of the steps under Oldman's feet broke, and the giant stumbled and almost squatted on the ground.

"What a hard door!" Oldman was surprised, "Let me give it another punch." ”

I saw the giant take two steps, as if he had slammed the door again with a punch with all his might, but the door still did not open.

"Landlord, this is not right, my punch, even if it is smashed on a stone, there should be a fist mark that is not big or small, what kind of material is this door made of, I smashed it twice, and there was not even a pit." Oldman leaned over to the door and looked at it.

Yang Yang was already eager to smash the door, but after hearing the giant's words, he took the initiative to give up.

Barbara wanted to try it with electric shock, but was also stopped by Cheng Shi, thinking that if the door thousands of years ago still can't be opened now, it shouldn't be a problem with the mechanism, but a problem with the materials that make up the door.

Cheng Shi glanced up: "Xiaoqiao, why are you still stunned?" Descend to scan and analyze the structure of the substance. ”

"Isn't this ship acting as a flashlight for you?" The information bridge muttered, and then released a fan-shaped blue light from the hull, in fact, this scanning light could not be seen under the super strong searchlight around its hull, but in order to prove that it was working, the information bridge deliberately turned off the two searchlights.

"The main structure of the building is made of materials with strong interacting forces. As far as the ship knows, it is only possible for races with advanced astronautical abilities to create this material. The information bridge was scanned and analyzed.

The so-called strong interaction force refers to the gap between the molecules that make up the substance to zero, and the material made by this technology will no longer vibrate, its surface friction coefficient will be zero, and the temperature can reach absolute zero, which is indestructible.

"But apparently the material they are making is not stable enough, and it is undergoing a qualitative change, but this qualitative change lacks the intervention of other substances in the vacuum, and the speed is relatively slow, otherwise it would not be possible for something else to stick to its surface." The information bridge further explains.

Cheng Shi stretched out his hands: "Then do we have anything to destroy it?" Now that you're here, you have to go in and have a look. ”

"Your watchman can break down the door with a gun, but pay attention to the yield, this is also a building more than 8,000 years ago, and it is easy to collapse if you are not careful."

Cheng Shi immediately asked the Kate Eagle to release his Watchman with gun, and then asked the others to stand on both sides of the building, while he activated the energy shield on his body and prepared to use the Warden gun to break the door.

When he was on the battlefield of Fetrech, Cheng Shi discovered a new way to play with his gun, which was to attack with scissor hands, and the gun would become a gun, so he raised his scissor hand in the direction of the door and tapped it gently

For a moment, he thought that in this way he could control the yield of the artillery.

Although he didn't worry about being stoned to death after the high-rise building collapsed after opening the energy shield, the scene of being dug out of the pile of debris of the building would still be a little embarrassing after all. So when he finished firing the cannon, he slipped and ran to a place two hundred meters away.

The fact is that the situation is similar to what he thought, and shaking the scissor hand slightly can indeed have the effect of controlling the attack yield, which is in line with the simple and practical characteristics of the empire's weapons that the goddess Wang said.

Cheng Shi fired a shot, but there was no explosion, the tower did not collapse, and the door and the surrounding door frame were gone.

Everyone waited for a long time more than two hundred meters away from the tower, and after finding that there was nothing abnormal, they all returned to the place where Cheng Shi had just fired the cannon.

"It seems that the landlord's weapon is still good." Oldman looked at the round hole that seemed to have been cut under the tower, and said in a gruff voice.

The entrance to the tower has been solved, and Cheng Shi asked the Kate Eagle to transform into a ship model to continue to act as a flashlight, and then the five of them officially entered the tower to explore.

"me, what the hell is this?" Cheng Shi was shocked to see the chaotic scene inside the tower.

This is obviously a man-made high-rise building, and its interior seems to be like a cave, and it is also a bit like the crystal pit on the mermaid planet, but this time their perspective is from the bottom up, it looks more bizarre and more eerie, only to see black crystal pillars gushing out from the ground, spiraling upward, as if they are growing, looking through the gap in the upward extension of the crystal pillars, everyone speculates that these crystal pillars should have pierced the floors of all floors inside the tower building. Although more than 8,000 years have passed, it can still be seen that there are many items scattered all over the hall on the first floor.

The structure inside the tower was not made of those high-strength materials, but it is unknown why the staircase inside the tower is still usable after all this time.

At first, Yang Yang jumped on the stairs a few times after seeing them, and after finding that the stairs were still solid, everyone looked for the stairs and walked up.

Everyone came to the second floor, there is no doubt that this place is also a mess, the crystal pillar continues to extend upward, relative to the first floor, some daily necessities can be vaguely seen on the floor of the second floor, Cheng Shi is worried that these things will be broken after picking them up, so he asked the information bridge to scan and analyze it first, and then try to pick it up and study it carefully.

"This should be a magical civilization, and from the analysis of material composition, these things on the ground are some spell-casting materials." Information Bridge reported after analysis.

Cheng Shi was stunned: "Magical civilization? So how can they have such a high level of technology? ”

"This cosmic space is likely to be the product of the explosion of the small universe, and it is normal for some situations that do not conform to the development laws of the main universe civilization, but the magic race is originally good at material science, but most of the materials they make are used for spellcasting. According to our understanding, when the mortal race first began to produce strong interaction materials, it was generally very unstable, and most of them were used for war, but if on the surface of the planet, the war damage caused by weapons made of this material was far less direct and lasting than that brought by nuclear weapons, and the difficulty of manufacturing nuclear weapons was much lower than that of making this material. Therefore, once the mortal race has produced a stable strong interaction material, it will generally be used to build spaceships, or used in space weapons. Even in the face of natural disasters, such as the ecological reset of the planet, they can make this material, and they should build a spaceship to escape from the ground, but they choose to build a house on the planet, which is more incomprehensible. The information bridge carefully analyzed all the current illogical situations.

"What if they can't get off the ground at all?" Yang Yang interjected coldly.
