Global Freeze: I built a doomsday safe house

The application of stellar energy is merely a theoretical concept for the sixth generation of humanity.

For example, a Dyson sphere is made by encasing the entire sun in a special material, which allows it to absorb all the energy emitted by the sun.

This is clearly unrealistic, because it's impossible to do with all the material from the other planets in the entire solar system combined.

However, for six generations with limited imagination, this was the only method they could think of.

However, today, Zhang Yi and his team witnessed a completely new method—the attraction and plunder of solar radiation!

It was able to distort sunlight, or rather, guide radiant energy, and concentrate it on the purple pyramid.

Even Lu Keran was astonished when she saw such advanced technology.

She calculated the energy harvesting efficiency of the purple pyramid and found that the solar radiation energy collected every second was equivalent to 1.2 tons of coal!

"It's...terrifying!"

Lu Keran clicked her tongue in amazement and murmured, "We always think about mining minerals, but we forget that the energy source of most fossil fuels is the sun."

Pointing to the enormous purple pyramid, she said to Zhang Yi, "This stellar-level energy harvesting device is equivalent to more than 3000 large-scale solar power plants!"

Yang Xinxin glanced at it, and even someone as calm as her couldn't help but take a deep breath.

"Although both utilize solar energy, the principles are completely different. The utilization of solar energy on Earth is simply like boiling water. But this pyramid directly absorbs the energy from solar radiation, with a conversion rate as high as 95%, and almost no waste."

Some have joked that no matter how advanced technology becomes, human history has progressed for so many years, and we still can't live without boiling water and throwing stones.

After all, almost all engines in this era were based on the principle of steam engines.

It wasn't until the advent of the era of superpowers that, due to the birth of superhumans and the emergence of ancient civilizations, progress began at a snail's pace toward a more advanced civilization.

"Brother, we're rich now!"

Lu Keran examined the pyramid and murmured, "It's unimaginable if ten thousand of these stellar energy harvesters were built on a single planet, all facing the sun!"

Zhang Yi quickly realized this problem as well.

The territory of Huaxu Kingdom is now very large, about five times the size it used to be.

Moreover, because the population is concentrated in cities, 90% of the area is uninhabited.

If we can install a large number of these stellar-level energy harvesters, then the future energy shortage problem can be completely solved!

"This thing... is the biggest thing I've gained from coming to Mars?"

Zhang Yi scratched his head, feeling that it was all a bit unreal.

Indeed, technology is the primary productive force. This may seem absurd, but it is undeniably true.

It's like having a desktop computer that's more efficient than ten thousand accountants using an abacus.

A stellar-level civilization dealing with a planetary-level civilization is truly a case of dimensional reduction.

Yang Xinxin said, "The important thing is to master the technology of this energy harvesting!"

"It can collect not only solar energy, but also geothermal energy."

"If the technology is applied to spacecraft, long-term space travel can be sustained without worrying about energy shortages."

As Zhang Yi listened to their conversation, his gaze toward the purple pyramid grew increasingly bright.

"In other words, this is priceless, right?"

"Of course!"

Lu Keran answered affirmatively.

Ling's expression remained indifferent; she wasn't particularly interested in this level of technology.

She glanced at the metal tower once more, as if checking its material, before looking away.

"The level of civilization here is no longer what you call Martian natives."

"This is a civilization that has mastered efficient energy conversion, a planet-level self-sustaining system, and the ability to transform all knowledge into structures."

"It's at least a level that won't appear until after the Third Age."

Zhang Yi asked, "You mean, back then, there was also a group of beings on Mars... like the Ehen race, who escaped Earth and migrated to Mars?"

Ling shook her head: "The technology of the Yihen tribe is not that backward. Don't joke around."

"But in subsequent civilizations, there will always be those who want to become the Ehen race."

"They saw their destiny as being shrouded by the Creator, so they tried to establish a sustainable system inside a planet outside Earth to escape the next purge."

"The results of it?"

"You've seen the results."

"The planet died, and they couldn't escape either."

Zhang Yi touched his nose, but didn't feel particularly sad.

A civilization can exist for hundreds of millions of years. If we let it live that long, it would probably have lived long enough by then.

Perhaps Martian civilization also chose to end itself and return to the ether.

Zhang Yi thought to himself with a touch of wicked humor.

"Alright, forget about all that crap! Anyway—"

His eyes shone brightly. "Excavating ruins is a good thing! Let's keep up the good work. Now, in addition to mining veins, we also need to search for valuable technological artifacts left behind by the Martians!"

With a wave of his hand, Zhang Yi spread the news, and the entire construction team's morale immediately soared!

The mechanical legion on the surface continued digging.

Over the next day, several more similar ruins were unearthed at different coordinates.

Some are semi-circular energy chambers, some are rows of metal columns that look like some kind of integrated computing device, and there is also a very obvious "dormant chamber cluster".

Those dormant chambers have all weathered away, with no biological residue inside, only a layer of dried paper-like traces.

When these things are put together, they illustrate one fact—there really was a highly advanced civilization on Mars, and it wasn't a scattered phenomenon, but a systematic one.

“The problem is,” Yang Xinxin frowned, “how could such a high-level civilization have absolutely no records?”

"Didn't you see it in Earth's historical records?"

"Have you seen this in the Lunarians' records?"

Zhang Yi thought for a moment and shook his head: "No."

"Unless they were deliberately erased."

"Or perhaps, their existence was the kind that shouldn't be remembered at all."

Just as they were discussing these things, another team working on the other side of the canyon sent back a message with a completely different atmosphere.

"We have discovered human remains."

The voice on the communicator was usually calm, but this time it was noticeably more subdued.

"The number is small; it should be part of the Mars exploration team from back then."

"Please take a look, Your Excellency."

The video feed came back.

It was a slope half-buried by wind and sand.

Five or six corpses dressed in old-fashioned spacesuits lay there in strange positions.

Some were trying to climb back, some were looking back in terror, and one even covered his head, as if to protect himself from something falling from above.
