Let you fight monsters, and you wake up Gatanjie?.

As the excavator started, the grab bucket dug into the lunar soil under the operation of the driver.

The process went very smoothly, and each scoop yielded a large spoonful.

The excavator put the excavated soil aside, and other astronauts walked over lightly and collected the soil into the storage bracelet.

Then the excavator started working again and did not stop until the bracelet of the astronaut was full.

The driver got off the excavator, aimed the storage bracelet at the position of the excavator, and pressed a button.

I saw a ray of light shining out and putting the excavator into the bracelet.

After completing the mission on the moon, the group took a group photo on the moon and then returned to the spacecraft.

"Oh, if we could have landed on the moon before, who knows how many missions we would have to carry out on the moon!"

As the spacecraft slowly took off, Zhang Kong looked at the gradually receding moon and said with emotion.

"Yes, but we have other tasks. You can take a rest first. We will have to collect more later."

Yang Yuanfei smiled and said to everyone.

There is a lot of space inside the spacecraft, and there is also a place for people to rest.

There's even a gravity simulation system that allows people to stand steadily on the floor of the spacecraft.

As for the respiratory system, it is even more advanced. You don’t even need to wear a space suit inside the spacecraft. There is no burden or impact at all.

The spacecraft flew at an extremely fast speed, and soon arrived at its next target - Venus.

As one of the planets that humans on Earth most want to explore, Venus has an atmospheric pressure ninety times that of the Earth and a surface temperature of 470 degrees.

However, all of this is not a problem for Daxia's current aerospace technology.

When the astronauts landed on Venus, they came out directly.

Even the excavators were released, not afraid of the high temperature at all, and started digging the soil of Venus directly.

At this time, everyone began to observe Venus with the naked eye.

As an terrestrial planet, Venus is very likely to have life.

Of course, this life could be a microorganism, not an animal.

When everyone looked at the surface of Venus from a higher place, they couldn't help but sigh.

Although Venus is a barren planet, but the terrain, mountains, and rivers that have dried up into sand beds... one can imagine that it was definitely full of vitality in the past.

Venus is now covered with yellow sand and stones. At first glance, it looks entirely golden.

“I think Venus is a bit like a wasteland version of Earth.”

After a moment of silence, Zhang Kong spoke to everyone.

"With the naked eye, we can see that this planet should have been full of life like Earth in the past."

"Venus is so close to the sun, and in such a harsh environment, it is impossible for life to exist."

An astronaut said.

"What if... Venus wasn't so close to the sun before?" Zhang Kong was stunned for a moment, then asked, "What if it was in that position in the Earth's orbit before?"

When these words were spoken, everyone was shocked.

Everyone in the Aerospace Department who was watching the live broadcast was also stunned.

Yes, if Venus was in the same position as the Earth's orbit before, then did these places, which are now full of loess and sand, also grow dense forests?

Have there ever been gurgling water and endless oceans?

Soon, everyone followed Zhang Kong's guess and continued to speculate.

If Venus was previously in Earth’s current orbit, then Venus’ current orbit should belong to Mercury!

The Earth is in the position of Mars...

And so on, all the planets move one orbit back.

"If the planets in the past all moved back one orbit, then what planet is moving to where Mercury is now?"

Some people can't help but feel a little scared when they think about this.

Could it be that the reason why this planet no longer exists is because it has entered the sun and become a part of this burning fireball...

terror!

Perhaps trillions of years later, Mercury will also merge into the Sun, Venus will enter Mercury's orbit, and the Earth will enter Venus' orbit...

Mars, the planet that is very likely to become the second home of mankind, will come into the orbit of the Earth, at the most suitable distance from the sun, and begin to develop life on the planet.

"In the long river of time, we humans are really insignificant."

Suddenly, someone from the aerospace department said with emotion.

Indeed, it is still unknown whether humans will become extinct in billions of years.

After all, human history has not even lasted tens of millions of years since its development.

After collecting the soil from Venus, Zhang Kong and his companions adjusted their mindsets and returned to the spacecraft.

Our next target will not be Mercury, as it is too close to the sun and the environment there is even more severe.

So the spacecraft flew towards Mars.

After passing through the Earth's orbit, the spacecraft soon arrived beyond Mars.

There is no wrong version in the 6 book forum!

Looking at this red planet, everyone's eyes were full of anticipation.

Human exploration of Mars has never stopped because it is the planet most likely to become humanity's new home.

After everyone passed through the Martian atmosphere and arrived inside Mars, they slowly landed on the ground.

However, Yang Yuanfei felt something was wrong. He seemed to have seen a building in the sky just now?

Am I dazzled?

"How can there be buildings on Mars? I must be hallucinating because I was so excited."

Doubtful, Yang Yuanfei shook his head.

If there is something on Mars, the explorers will naturally detect it later.

You don't need to worry about this matter.

When the hatch slowly opened, a group of explorers also landed on the surface of Mars.

However, Zhang Kong suddenly froze, his eyes looking towards the ground not far ahead, where there were several shoe prints.

This footprint looks... a bit like the pattern on the sole of a sneaker?

"Look, are those footprints???"

Puzzled, Zhang Kong couldn't help but speak out.

Everyone was stunned, and then looked in the direction Zhang Kong pointed.

Indeed, there were several footprints on the ground not far ahead!

An automatic unmanned probe used for live broadcast also flew over, with its camera pointed at the ground.

This scene stunned everyone in the aerospace department.

No, who the hell landed on Mars ahead of time?

No one said a word?

Is it Eagle Sauce? Or Big Bear?

"Wait, there seems to be a label on this shoe print?"

"Fuck, it's true!"

"What the hell! Pull back the power?!"

Everyone was stunned when they saw the shoe print label clearly displayed on the screen after it was enlarged.

The Chinese characters on the label indicate that the shoes are made in China...

In other words, some Daxia humans landed on Mars in advance, but it is not known what method they used.

"Report!!!!"

At this moment, Zhang Kong's voice suddenly shouted out excitedly.

"There seems to be a tree in front! A big green tree!!!"
