Doomsday: spore invasion, my system has no upper limit

This is a wandering planet that has separated from its host star, drifting in the dark and cold deep space of the universe.

After scanning, it was found that the planet still has an atmosphere, but most of the atmosphere on the surface has become solid, and the entire planet is wrapped in solid ice.

The composition of the ice closest to the surface is water, and above that is 78% nitrogen and 21% oxygen, with 0.9% argon and 0.1% other gases.

On the surface of the ice there is only a thin layer of liquid gas less than ten centimeters, and free gas less than one millimeter.

The composition of this atmosphere really shocked everyone, it was exactly the same as Blue Star.

If there are intelligent creatures hidden underground, then 99% of them are humans.

On the surface of the planet under the ice layer, there are many huge city ruins and tens of thousands of huge planetary engines, which seem to be the main star that those planetary engines pushed the planet away from.

The size of the planet is almost the same as that of the blue star, and it still maintains a slow rotation, which proves that the inner core has not been extinguished, and the geomagnetism still exists.

Then it must be warm underground.

Sure enough, after scanning, there are signs of a large number of biological activities 1000 meters underground.

This underground city is as big as the first-tier cities on the blue star, and millions of individual lives live there.

Zheng Chen smiled and said, "Okay, Yuzhi, you can scan the whole city again."

Nima!It turned out that the robot was interrogating!Zheng Chen wanted to take the four of them away directly, but then he thought, why not see if the robot here is what it said it wanted to ask for help.

The appearance is similar to that of a human being, and it should be a robot made by intelligent creatures here.

Li Yuzhi immediately scanned the entire city with a tricorder, and found that there are more than 300 million residents in the city, and there are many small animals.

But then the window closed and there was no movement.

If it wasn't for the underground of the wandering planet 3.2 million light years away, Zheng Chen would have directly regarded him as a blue star human.

But regardless of the residents or the small animals, they all stayed in the room, as if they were imprisoned as the distress signal said.

As soon as the words fell, a window opened on the wall, and a mechanical arm sent in four listings from inside, and gave them to Zheng Chen and the others respectively.

Suddenly, the tricorder shows five residents running, followed by a robot chasing them.

The strange thing is that they walked all the way to the city, and they didn't find a humanoid creature on the road.

Immediately afterwards, the voice of interrogation appeared in the room, "Why is there no information about you in the city's system, and which district were you four born in?"

Then Zheng Chen was directly teleported to the biggest underground city.

After scanning with a tricorder, Li Yuzhi found that this fungus was not as terrifying as the ancient spores, but instead contained a lot of sugar, protein and vitamins. Obviously, this is the food of local organisms.

Zheng Chen and the others felt a little happy when they heard it. It seems that their appearance is similar to the intelligent creatures here.

Instead of restraining their conversation, the robot led them all the way into a sturdy room.

There are 10,000+ or ​​even millions of life forms in each city, and there are still a lot of thermonuclear fusion mechanical energy moving.

Then without saying anything, he followed the robot and walked towards the center of the city.

The voice of the interrogation paused, and suddenly became very stiff and said: "Error, system error, immediately repair the system and re-enter the information of the four people."

Seeing this, Zheng Chen quickly located the three injured residents, and teleported them into an empty subspace.

Then lock the door.

Zheng Chen said: "No, even at night, there are people who work at night, it is impossible to all sleep in the house, it is indeed a bit weird here."

Xue Wen said: "Maybe it's their night now, everyone is resting."

Afterwards, Zheng Chen and the others entered the secondary space to take a look, and found that they were three local residents who looked very human.

The ground and tens of thousands of stone pillars are also covered with self-illuminating fungi everywhere, illuminating the entire underground city very brightly.

They were avoiding the pursuit of robots, and suddenly came to this sunny subspace, thinking that after being killed by robots, they entered the afterlife.

All three are around 16 years old, and all are girls. There is little surprise about their appearance, but they are all beautiful.

Xue Wen said with a smile: "[-]% is to give us a dormitory."

There are dozens of huge underground cities 2000 meters underground, and the temperature inside reaches 23 degrees Celsius.

Zheng Chen thought that the other party was the administrator of the city, so he said in their language: "The four of us were born in the fungus field. It's your fault that we don't have any information about us. How would we know?"

The four of them looked around and saw that this was a huge artificial cave, and the roof of the cave tens of meters above their heads was covered with self-luminous fungi.

"Liu Huatong, send a message to Blue Star, saying that we have encountered a distress signal, and it will be delayed for a few days, so that they can contact you at any time in case of emergency."

Zheng Chen laughed in his heart, "Take the handle first, and see what happens."

Li Yuzhi quietly scanned the nearby buildings with the tricorder, and said, "People here should all be sleeping in their rooms, and the vital signs that were scanned are all quietly staying in the room."

They were in a large field of glowing fungi, far from the main city.

Han Lingxue smiled and said, "I'm picking a breeding partner for you!"

In the blink of an eye, two residents were killed by robots, and the vital signs of the other three were also weakened.

And that message was sent from the largest underground city.

After a while, the voice sounded again, "You have been renumbered. The male is Fungi Field No. [-], and the three women are Fungus Field No. [-], No. [-], and No. [-]. We will reassign your residences to match your breeding partners."

He came to the four of them and issued a warning, asking: "Which district are you four residents from? Why did you come to the field without permission? Follow me immediately for investigation!"

When Zheng Chen entered the underground city, he was immediately stunned by the scene in front of him. Han Lingxue, Xue Wen, and Li Yuzhi also hurried out from the secondary space.

An angry Xue Wen snorted, "Sister, you will bully me!"

Just when the four of them were about to leave and walked towards the main city, mechanical equipment suddenly came running from a distance.

Covering his eyes and not daring to look at the dazzling sunlight outside, Zheng Chen knew that they could no longer adapt to the sunlight because they lived underground all year round, so he quickly dimmed the light in the secondary space.

It turned into a cloudy dusk, and the soft and dim light made the three girls put down their hands covering their eyes, and looked at Zheng Chen and the others in horror.

A girl asked: "Excuse me, are you our ancestors? Are you waiting to pick us up in the afterlife?"

Another girl asked, "Where are numbers 6 and 2?"

Zheng Chen said: "Don't be afraid, this is not the world after death, we came from outside."
