On a desert of desert smoke.

The two far-flung Mars cars meet together.

Pushing the car door out, Sun Wenchel looked at himself and walked up to Han Kangyu in his costume. He asked with an anxious expression on his face.

“Did you find someone? ”

His eyes were filled with a heavy divine color, and Sun Wenchel shook his head.

“No. I've looked everywhere for the nearby generation, don't tell me who it is, I haven't even seen the crack he fell through... what about you? Any leads? ”

When I heard this bad news, Han Kangyu's face was a little ugly.

“Neither do I. ”

He searched almost every corner he could find and even ventured a short distance towards the inside of the Hell's Gate Mountains, but as his teammate Sun Wenchel said, let alone a figure, he didn't even see a slightly deeper crack.

Pessimism grew from his heart, and he was now increasingly wondering whether the same extent of disappearance was still alive.

“It's hard to do...”

With the sand glued to the mask of the costume, Sun Wenchel looked headachedly at the mountains next to the two people, “Whether we want to turn this place over or it's too impractical... what's going on over there at headquarters? Didn't the captain apply for backup? ”

“Without support," shook his head, and Han Kangyu said in a heavy tone, "the Ground Command Center asked us to use all the resources available at the scene to carry out a search and rescue of the missing persons. Beyond that, there is no better way for them to support us than by indicating that they will use the equipment already deployed on Mars. ”

“So there's no backup?” Sun Wenchel sighed, "but speaking of which... a two-week voyage, even if it arrived, most people were gone. ”

Equipment already deployed on Mars…

With the exception of a few probes that were dropped a long time ago, the only useful equipment deployed on Mars, they suspected, seemed to be themselves.

Han Kangyu's eyebrows floated as he glanced at the time on his wrist.

It's been almost five hours.

Every minute that passes, the hope of survival is diminished.

Yet just as the two of them were discussing how to proceed with the next rescue effort, deep behind the rolling red sand, a very unnatural black spot suddenly appeared.

Gradually, the black dot approached, revealing its contour in the eyes of the two.

As soon as I saw the outline, the two people who were still discussing the rescue work were dazed.

They had been looking for the culprit for more than five hours, riding in an unmanned automated reconnaissance vehicle, wandering from their side.

“Thanks.”

He gently photographed the roof of the survey vehicle and jumped off the roof with his whole body dirty and like a coal mine.

As if to hear this gratitude, the automated survey of the cameras on the top of the car took place at a humanized location, followed by a 180 degree turn, continuing with its previous mission and heading deep into the desert.

Fan Tong then looked at his two staring teammates and gradually appeared with a shameful look on his face and lowered his head.

“Sorry to bother you. ”

“Do you know what I want to do now?” Nagging in his mouth, Han Kangyu's eyes stared at him dead, “I want to give you a fucking punch right now. ”

“I know I want to punch myself... but now is not the time to say this,” The shameful expression on my face gradually wrote a little complicated, Fan Tong took a deep breath and continued with a bitter smile, "I have an important discovery to report. ”

……

Mars Science Examination Station.

In the event room, which was used as a temporary conference room, he changed into plain clothes and sat at the conference table with his four teammates, telling them all about his insights in the underground world in a flat, straightforward manner.

After listening to his story, everyone, including Captain Liang Yucheng, stood there.

Mars civilization?

Holy relics?

It sounds like they're actually living in some big science fiction movie...

“You mean... you saw aliens underground?” Reaching out and squeezing his eyebrows, Leung had organized a confused thought and continued, “And then it wasn't actually with Martians, from a third party civilization outside the solar system, who lived hundreds of millions of years ago and told you that there were civilizations here that were beyond the industrial age? ”

Sun Wenche, who had been silent, suddenly said.

“People are said to be hallucinating in extreme environments. ”

“I swear it's not a hallucination," Fan Tong continued in a serious tone, looking at his pal with an obvious expression of disbelief on his face, "We reported each other's doors, calling ourselves‘ sacred relics’ and mentioning the civilization that once existed on this planet… that is, the Martians. In fact, I did find evidence of the existence of Mars civilization underground, and on the way to that place, I passed a corridor with something like a coffin on either side of that corridor. So it's nothing wrong with claiming to be a sacred relic, and it does look like a funeral to me. ”

A key message was captured from his monologue and Sun Wenzhe immediately asked.

“Where's the sample? You found something so amazing, don't say you didn't sample it. ”

“It's in the sample bank, but if you want to extract the DNA from that thing, I think you should give it up. Apart from being able to barely identify the artificially carved traces of that row of 'coffins', the vast majority of the material has essentially weathered into biomass debris rock. Although not tested for isotopes, experience alone can infer that the age of biomass debris is longer than that of trichlorfon fossils. ”

Sun Wenzhe: “You have to try everything to know. ”

“Whatever. It's your specialty anyway. ”

Looking back at Fan Tong on the chair, the beam frowned.

“Let's not talk about Mars civilization… Are you sure you saw another civilization in the ground? ”

“No, not exactly, the situation was very strange. I can feel him in the neighborhood, but maybe he's hiding, and I can't even find him. He connects directly to my communication channel and even communicates with me with a standard plain call. By the way, I also ran into an invisible wall there. Anyway, there are a lot of things about evil doors... Don't look at me like that, I can swear on my academic reputation, this is definitely not a hallucination! ”

“Forget it, I'll show you the evidence. ”

Fantong took the wrist-mounted computer off his arm and threw it on the conference table.

Looking at the wrist-mounted computer, Han Kangyu frowned and asked.

“What is this?”

“As I said earlier, we asked each other a question in good faith after a friendly question mark. I asked him who he was, and he dumped a math question in front of me... this is it. ”

Fan Tong opened the information panel in the wrist-mounted computer and read the text message.

Five people sitting at the table approached the past.

Staring at the mathematical question for a while, Xiao Xiao, an electrical engineer who had not spoken, continued with a strange expression, “Looks like a high number of questions. ”

Sun Wenche, standing next to him, laughed bitterly.

“… this is not a very high question. ”

Liang had immediately looked at him.

“Will you do it? ”

At this moment, Han Kangyu suddenly intervened.

“If I remember correctly, should this be ABC's guess? ”

“Exactly, it's ABC's guess,” Look at the four different facial expressions in the conference room, Sun Wenche is in a complicated spot, “let alone a few of us outside. ”

“It's back on Earth… I'm afraid we can't find a solution to this problem. ”
