On the desolate desert.

Two distant Rovers converged.

Push open the door and jump out. Look at Sun Wenzhe who is coming to him. Han Kangyu, wearing a spacesuit, walks forward with a big step. He asks with an anxious expression on his face.

"Have you found anyone?"

His eyes were full of dignified looks, and sun Wenzhe shook his head.

"No. I've looked for the generation nearby, let alone the human figure. I didn't even see the crack he fell down Where are you? Is there any clue? "

Hearing the bad news, Han Kangyu could not help looking ugly.

"I don't have one."

He searched almost every corner he could find, and even ventured a short distance towards the interior of the Hellgate mountains. However, as his teammate sun Wenzhe said, not to mention the human figure, he didn't even see a slightly deeper crack.

Pessimism gradually emerged from his heart, and now he doubts more and more whether fan Tong is still alive.

"It's not easy..."

After wiping the sand stuck on the mask of the spacesuit, sun Wenzhe looked at the mountains next to them with a little headache. "It's unrealistic for us to turn this over What's the situation at headquarters? Didn't the captain apply for support? "

"No support," Han said with a heavy voice, shaking his head. "The ground command center asked us to use all the resources available at the scene to search and rescue the missing people. In addition, they have no better way to support us than to say they will use the equipment already deployed on Mars. "

"That is to say, there is no support?" Sun Wenzhe sighed, "but it's also The two-week voyage, even if it is arrived, most of the people are gone. "

Equipment already deployed on Mars

In addition to several probes dropped a long time ago, the available equipment deployed on Mars seems to be only themselves.

Looking at the time on the wrist computer, Han Kangyu could not help but look a little worried.

Almost five hours have passed.

Every minute, the hope of survival is less.

However, when the two discussed how to carry out the next rescue work, there was a very unnatural black spot behind the rolling red sand.

Gradually, the black spot came close and showed its outline in their eyes.

When they saw the outline, the two men, who were still discussing the rescue work, suddenly lost their eyes.

Only to let them worry about finding the culprit for more than five hours, is riding a self driving automatic survey vehicle, staggering from their side.

"Thank you."

Lightly patted the roof of the survey car, and the whole body was dirty like the coal mine, jumping off the roof.

As if to hear this thanks, the camera on the top of the automatic survey car was humanized, and then came a 180 degree turn, continued his previous task, and went to the deep desert.

Seeing the unmanned reconnaissance vehicle probably belonging to Jinling Institute of higher learning go away, fan Tong then looked at his two stunned teammates, and gradually a little ashamed expression appeared on his face and lowered his head.

"Sorry to worry you."

"Do you know what I want to do now?" He said, Han Kangyu's eyes fixed on him, "I want to give you a punch now."

"I know. I want to give myself a blow But now it's not the time to say that, "fan continued with a deep breath and a wry smile as the ashamed expression on his face became more complicated." I have important findings to report. "

……

Mars research station.

Fan Tong, who was treated as a temporary meeting room and put on casual clothes, sat at the meeting table with his four teammates and told all his experiences in the underground world in a flat and straightforward way.

After listening to his story, everyone, including captain Liang Youcheng, was stunned.

Mars civilization?

Relics?

It sounds like they're actually living in a science fiction movie

"You mean Did you see aliens underground? " Holding his brow and heart, Liang Youcheng sorted out the confused thoughts and continued, "then in fact, it's not with the Martian. It's from a third civilization outside the solar system. He has lived for hundreds of millions of years and told you that there are civilizations in the industrial era here?"

Sun Wenzhe, who had been silent all of a sudden, said.

"People are said to have hallucinations in extreme environments."

"I swear it's not an illusion," fan Tong continued in a serious tone as he looked at his teammate who was obviously disbelieving. "We reported to each other. He called himself a" relic "and mentioned the civilization that once existed on this planet That's Martian. In fact, I did find evidence of the existence of Martian civilization underground. On the way to that place, I passed a corridor with coffins on both sides. So there's nothing wrong with it claiming to be a relic. In my opinion, it's quite like a funerary object. "A key message was captured in his monologue and sun Wenzhe immediately asked.

"What about the samples? You've found such amazing things, let alone you didn't sample them. "

"It's in the sample library, but if you want to extract DNA from that thing, I think you should give up the idea. In addition to being able to barely recognize the traces of artificial carving on the row of coffins, most of the materials have basically weathered into biomass clastic rock. Although there is no isotopic test, I can infer from experience that the age of biomass debris is only longer than that of trilobite fossil. "

Sun Wenzhe: "you have to try everything to know."

"Whatever you like, it's your major anyway."

Looking at fan Tong leaning back on the chair, Liang Youcheng frowned.

"Let's not talk about Mars civilization first Are you sure you're down there and see another living civilization? "

"No, not exactly. It was a very strange situation. I could feel him nearby, but maybe he was hiding. I couldn't find him. He directly connected to my communication channel, and even spoke a standard Mandarin to communicate with me. By the way, I met an invisible wall there. In short, there are many things about evil gate Don't look at me that way. I can swear by my academic reputation. It's not an illusion! "

"Forget it. I'll show you the evidence."

With that, fan Tong took the wrist computer off his arm and threw it on the conference table.

Looking at the wrist computer, Han asked with a frown.

"This is?"

"As I said before, after the friendly question mark, we asked each other a question in good faith. I asked who he was, and he threw a math problem in front of me That's it. "

With that, fan Tong has opened the information panel of the wrist computer and read the text message.

The five people sitting at the meeting table came close to each other.

After staring at the math problem for a while, Xiao Hong, an electrical engineer who had not spoken, continued strangely, "it looks like a high math problem."

Hearing this, sun Wenzhe standing beside him gave a wry smile.

“…… This is not a high number problem. "

Liang Youjian looks at him.

"You can do it?"

Just then, Han Kangyu suddenly chimed in.

"If I remember correctly, it should be ABC guess?"

"Yes, it's ABC's guess." looking at the four teammates with different expressions in the conference room, sun Wenzhe looked complicated and nodded, "let alone some of our amateurs."

"Back to earth I'm afraid we can't find one who can solve the problem. "
