Twenty minutes later!

Wang Bo and the other three came to the place where the sun's rays had previously been reflected.

They found that there were actually some smooth blue-gray stones.

This made Wang Bo a little confused.

Because almost all the stones on Mars are brown stones, and there are very few stones of other colors.

"There are so many blue stones here, and the surface is so smooth?" one team member said.

Wang Bo and the other three stepped forward and began to study.

Such a strange stone appears here, maybe there is some unknown secret.

Maybe it contains the californium substance they are looking for.

Although the probability of this is very small, Wang Bo and the others still hope that a miracle will happen.

After half an hour of research, they discovered that there was nothing special about these stones.

They used tools to break open the stone and found that it was composed of ordinary calcium carbonate and silica.

There is no difference from the ordinary stones on Blue Star.

"Captain, it stands to reason that these stones will definitely oxidize on Mars and turn into brownish red."

"Do you remember the big storm last month? It was in this exact location."

When the two of them heard what Wang Bo said, they immediately understood.

These stones were originally underground stones, but the huge storm at that time blew away the stones above them.

If you analyze it this way, there is really nothing curious about it.

"It seems we made a fuss. Haha..."

"Yeah, it's getting late, let's go back!"

Just when Wang Bo and the others were about to go back, a gust of wind blew from behind them.

One of the team members turned around and was immediately startled.

"Captain, Feng... storm!"

Wang Bo turned around hurriedly and was immediately startled.

Sure enough, dozens of kilometers away, yellow sand covered the sky and blocked the sun, blocking their way back.

But the other three directions were all hills and ravines, making it impossible to pass.

"Captain, our way back is blocked, what should we do?"

Wang Bo looked around and saw that there was no other way.

It is very dangerous to encounter a storm on Mars.

The power of these storms is very powerful, equivalent to Blue Star level 18-20 storms.

A stone weighing hundreds of kilograms can be easily rolled up into the sky.

Let’s talk about Wang Bo and the other three in particular.

As long as you are caught in the storm, you will definitely die.

Although they were prepared to die in four days, no one wanted to die in the storm.

"Get in the car."

Wang Bo said to his two teammates.

Subsequently, Wang Bo drove the Mars rover to the right.

Through observation, he found that the storm on the right was relatively weaker, and decided to run in that direction.

Maybe there is still hope of escaping.

But Wang Bo still underestimated the storm on Mars. As the storm advanced, the wind continued to expand outward and traveled very fast.

The speed of the rover cannot be compared with the speed of the storm.

Seeing the storm approaching, Wang Bo was heartbroken.

It seems that they are in doom today.

At this moment, a teammate said to Wang Bo.

"Captain, there is a hole there."

Wang Bo looked in the direction of his finger, and sure enough he found a cave not far away.

The entrance of this cave is very round, and it looks like someone built it deliberately.

The key is that there are only three of them on Mars, Wang Bo, and no one else?

But at this time, Wang Bo and the others couldn't allow them to think too much.

The storm was very close to them.

Wang Bo was right and drove the Mars rover towards the cave.

Fortunately, the cave was not far from them, and they quickly reached the entrance.

"get off!"

"Enter the hole!"

Wang Bo and the others dropped the rover and ran into the cave.

"There are rocks here. Let's block the entrance to prevent gravel from coming in."

With the cooperation of Wang Bo and the others, they had just blocked the entrance of the cave when the storm came as promised.

"call……"

"Woooo..."

"Bang..."

The sound of the storm outside was very terrifying, like the howling of terrifying demons and monsters.

Wang Bo and the other three finally breathed a sigh of relief.

At this time, they began to look into the cave. Since the entrance to the cave was blocked, they found that they could not see anything.

Wang Bo turned on the flashlight.

Only then did the cave become brighter.

Wang Bo stood up and touched the cave wall and found that it was very smooth.

"Huh?"

Wang Bo's curious voice made both teammates look at him.

"Captain, what's wrong?"

"This cave doesn't look like it was formed naturally at all."

"Isn't it naturally formed?"

The two teammates were a little confused, but when they saw the smooth cave wall, they immediately started touching it out of curiosity.

"Why are the cave walls so smooth?"

"It seems to have been polished."

"Did life really exist on Mars before?"

One of them said.

Before they landed on Mars, Blue Star scientists had been arguing over whether there was life on Mars.

Many scientists believe that there is life on Mars.

They believe that there are "tough" organic molecules in the 3 billion-year-old sedimentary rocks near the surface of Mars.

As well as seasonal changes in the amount of methane in the atmosphere, organic molecules contain carbon and hydrogen and may also contain oxygen, nitrogen and other elements.

Although the imagined Mars is very harsh and life cannot survive, these "tough" organic molecules are all signs of life.

Wang Bo and the others survived on Mars for 176 days and discovered many incredible places.

There are many indications that the possibility of life existing on Mars is very high.

And today they discovered this smooth cave, which further confirms the possibility of life on Mars.

"Come on, let's go take a look, maybe we'll find something."

Wang Bo said to the two team members.

The storm of foreign names will not disappear for a while, so they took advantage of the time to explore the cave.

Wang Bo looked inside with a flashlight and found that the passage not far away turned a corner.
