Age of Cataclysm: I can light up the technology tree

As the captain of the team, Hong Fan is responsible for the lives of all the team members on his shoulders.

Even if the possibility of encountering danger is only 0.01%, he must choose the most stable approach.

Under Hong Fan's order, several team members ran towards the planetary landing vehicle not far away with nervous expressions.

As for Hong Fan, he slowly followed the back of the team, holding the engineer shovel that had just been thrown on the ground, and vigilantly observed the surrounding rock walls and sand.

After all the team members entered the hatch of the planetary landing vehicle, he controlled the mechanical exoskeleton and ran quickly towards the open hatch.

During this period, he held the engineer shovel in his hand tightly, fearing that there would be any unexpected situation.

After all, this is how it is played in movies or TV series!

When the captain returns to the safe zone, some accidents often occur.

Then... it is the classic scene of Calabash Brothers saving his grandfather.

He doesn't want to encounter such a scene!

Hong Fan looked at the surrounding environment vigilantly, while thinking wildly in his heart.

Fortunately.

The road was smooth, except for the yellow sand all over the sky, there was nothing unusual.

He kicked his right leg hard, and with the help of the exoskeleton armor, Hong Fan directly crossed the last three meters and entered the planetary landing vehicle.

"Close the hatch!"

The moment the voice fell, the same hatch as the starship slowly fell down, making a dull sound.

The heavy hatch gave everyone a sense of security.

In the communication device, only a series of slightly rapid breathing sounds remained.

[The pressure has stabilized. ]

A gentle female voice sounded in the helmet.

Hong Fan took a long breath, chuckled and said: "Let's go to the disinfection room."

"Next, wait for the news from the Earth."

...

Above the Dawn Star.

[Earth], command center.

Fang Xu frowned, looking at the huge holographic projection in front of him, which was already full of red warnings.

"Hematite..."

He muttered to himself: "How could there be hematite on the Dawn Star?!"

Yes, it's not just Hong Fan's team.

Almost every team responsible for resource exploration has sent similar reports.

There is a large amount of hematite underground on Dawn Star!

This is totally inconsistent with human cognition!

Could it be that...

Did oxygen really exist on Dawn Star before?

Even, has life appeared on this desolate planet?

For a moment, Fang Xu was in a state of confusion.

Before there was a definite answer, the infrastructure work that had just begun on the surface of Dawn Star had been completely stopped.

And those exploration teams scattered in various areas also returned to the relatively safe planetary landing vehicle, waiting for instructions from [Earth].

After thinking for a while and not coming to a conclusion, Fang Xu turned his head and asked the scientific researcher beside him: "Is Feng Yuanliang here?"

"Here!"

A hurried male voice came from the gate of the command center.

The middle-aged man panted and ran to Fang Xu in a hurry: "Academician Fang, are you looking for me?"

Fang Xu nodded gently and signaled the holographic projection in front of him with his eyes: "You are studying cosmic mineral resources. Let's see what's going on."

The middle-aged man didn't have time to catch his breath and quickly looked forward.

Just one glance.

He widened his squinting eyes.

"Hematite?!"

"How is it possible?!"

Looking at Feng Yuanliang who had the same reaction as him, Fang Xu shook his head helplessly: "Academician Feng, is it possible for hematite to appear on the current Dawn Star?"

"Impossible! Absolutely impossible!"

Without any hesitation, Feng Yuanliang denied it directly.

"Then... what about before?"

Hearing this, Feng Yuanliang suddenly hesitated: "Hiss..."

"You mean, there was oxygen on the Dawn Star in the past?"

"Based on the current data, this possibility is not great."

"Unlike Mars and Guangwei-1, the gravity of Dawn Star is enough to retain the atmosphere."

"What's more, we have not found any traces of oxygen at present." Feng Yuanliang paused, "Except for these hematites."

"This is strange..." Fang Xu stretched out his hand and rubbed his eyebrows, muttering to himself, "It can't be that these hematites floated from outer space."

The speaker is unintentional, but the listener is attentive.

Feng Yuanliang's confused eyes brightened a little instantly!

He clapped his hands suddenly, his expression was extremely excited: "Academician Fang! You are right!"

Fang Xu: "???"

"I, what did I say?"

"It floated from outer space! The source of these hematites is probably that Guangwei-1!"

...

After some explanation.

Fang Xu nodded thoughtfully.

"You mean, when the atmosphere of Guangwei-1 was relatively intact, the violent storm inside it raised countless hematite powders."

"And these powders crossed more than 100,000 kilometers and fell into the atmosphere of Dawn?"

Feng Yuanliang nodded repeatedly: "Yes, that's the process."

"Academician Fang, look." He stretched out his hand and dragged across a holographic projection, "We assume that Guangwei-1 had a relatively complete atmosphere in the past."

"Under the strong gravitational force of Dawn, its atmosphere is enough to produce extremely powerful storms!"

"Similar phenomena have been discovered in human history."

"Back then, humans discovered hematite on the surface of the moon."

"It's incredible, isn't it?" Feng Yuanliang sighed, "How can hematite appear on the surface of the moon without any atmosphere?"

"The reason behind it is actually very simple."

"The strong solar wind blows the oxygen on the surface of the earth to the moon, thus forming hematite."

Fang Xu was slightly moved and quickly said: "Zero, simulate it and see if such a situation is possible on Dawn."

A few minutes later.

The scene described by Feng Yuanliang appeared in the holographic projection.

"Then...how to prove the correctness of this speculation?" Fang Xu asked softly.

In the absence of conclusive evidence, speculation can only be speculation.

"Simple."

Feng Yuanliang pondered for a moment, and a gleam of light flashed in his eyes.

"Let these exploration teams conduct deep drilling work."

"If nothing unexpected happens, these hematites will only be evenly distributed at a certain depth."

Fang Xu thought for a moment and suddenly realized.

It is indeed the case.

Under the influence of the powerful storm on Dawn, the hematite powder will inevitably be evenly distributed all over the world.

The so-called specific depth depends on the integrity of the atmosphere of the first moon.

When the atmosphere of the first moon is loose to a certain extent and cannot stir up a strong enough storm, these hematite powders will eventually be buried under the yellow sand, just like water without a source.

Only a small amount of hematite powder will be lifted up by the strong storm and dispersed in the atmosphere!
