Cataclysmic Era: I can unlock the tech tree

"This is an extremely large and highly difficult project."

"Through various calculations, and with the help of carbide and star gold-carbide composite materials, theoretically, we can build such a megastructure."

"Note that this is only in theory." Lü Yongchang sighed, shook his head, and said again, "It will consume a lot of time and a huge amount of resources."

"In addition, it needs to withstand impacts from various small and micro celestial bodies, and use its propulsion system to constantly adjust its trajectory to ensure that it does not fall into the interior of the star..."

"possible……"

At this point, Lü Yongchang pondered for a moment: "There aren't enough resources in the Gliese 555 star system to build such a megastructure."

These words immediately sparked a murmur of discussion in the meeting room.

"That……"

"Perhaps we can reduce its coverage area."

He Bilin's voice rang out in the conference room.

Under everyone's watchful eyes, he reached out and manipulated the holographic projection.

As he moved, the area of ​​the black spherical shell that enveloped the entire red dwarf star in the 3D simulation image continued to shrink, eventually becoming a series of ring-shaped structures rotating around the red dwarf star.

"Dyson hood." He Bilin looked at the brand-new model and nodded in satisfaction.

"By increasing or decreasing the number of Dyson rings, we can adjust the energy utilization of the host star at any time."

"At the same time, it can also reduce the possibility of being hit by small celestial bodies."

Lu Yongchang looked at the slowly rotating concentric ring model in front of him and nodded thoughtfully.

"That is indeed a good solution."

"only……"

"The construction period is still too long."

As he spoke, Lü Yongchang waved his hand, revealing a brand new projection.

"I have an idea."

As he spoke, he quickly sketched a few lines on the newly opened holographic projection.

With the rendering of Zero, a brand-new simulation appeared before everyone.

At the very center of the projection is a reddish dwarf star—Gliese 555.

Around this red dwarf star, there are clusters of cloud-like devices.

"A distributed Dyson sphere, or perhaps a Dyson cloud," Lü Yongchang shrugged. "This should be the simplest of the three architectures."

"Ten Phoenix One antimatter generation devices can be integrated on each cloud."

"We can even increase the number of 'clouds' at any time to control the production efficiency of antimatter."

"There are many advantages, but there are also disadvantages."

"Its energy absorption efficiency for Gliese 555 is not very high, at least not as high as that of a real Dyson sphere."

Lu Yongchang turned his gaze to the Dyson Circular Ring beside him, his eyes gleaming: "Perhaps... we can combine the Dyson Cloud with the Dyson Circular Ring."

"Let's start with the less difficult Dyson Cloud project."

"We will consider implementing the Dyson Belt project after the antimatter engine is successfully developed."

"As for the Dyson sphere project in its true sense..."

"It's not too late to consider this after human technology has advanced to a higher level."

Lü Yongchang's plan immediately gained the support of many people.

Compared to the enormous Dyson sphere and Dyson ring, the distributed structure of the Dyson cloud is undoubtedly more suitable for current human productivity.

……

After the plan was finalized, the Academy of Sciences, under the leadership of Lü Yongchang, immediately began working overtime.

A month later, the design drawings for the first phase of the Dyson Sphere project—the Dyson Cloud—were officially released.

After several simulations and verifications, engineering ships and the [Taotie] supply ships left Dawn Star and headed towards the center of the Gliese 555 system.

While the Dyson Sphere Phase I project was underway, the research and development of the antimatter engine was also gradually progressing.

As an entry-level technology for a Level 4 civilization, the difficulty of its research and development is self-evident.

……

Thirty years later, in the year 2500 of the Earth calendar.

The Dawn Star environmental renovation project has finally come to a close.

Lu Yongchang looked at the various data displayed in the holographic projection, his eyes gleaming with excitement.

The outside atmospheric pressure has dropped to 2.5 standard atmospheres.

The oxygen content is slightly lower than in Earth's time.

However, at 2.5 standard atmospheres, this difference will not have any impact on humans.

Nitrogen, carbon dioxide...

The Atmosphere Changer, which covered all the oceans, has also died of natural causes and sunk to the bottom of the sea.

After a hundred years of transformation, Dawn Star finally became the second Earth in Lü Yongchang's mind!

"Zero, tell Councilor Hong." Lu Yongchang took a deep breath, suppressing his surging emotions, "Open all ports in one month!"

"We need to get out here!"

……

A month later.

A corner of City One.

Hope was awakened by a jarring alarm clock.

After a very brief moment of confusion, he sprang out of bed with a somersault.

After hurriedly finishing his washing up, he quickly walked out of the house.

He was enjoying his vacation after returning from Ice Giant, and he never imagined that he would be able to witness this historic moment!

He raised his wrist and glanced at his watch.

There is less than an hour left.

"That old bastard Hansent..." Hope clicked her tongue softly, her brow furrowed, and said, "He must have overslept again."

While talking to himself, he changed direction without hesitation and walked towards the residential area not far away.

Thinking about what was about to happen, he twitched his nostrils and took deep breaths, trying to suppress the agitation in his heart.

But to no avail.

Now, even the air is filled with a restless atmosphere, constantly stimulating people's fragile nerves!

Along the way, you could hear people talking with great anticipation everywhere.

The port is opening!

They can leave the gated city now!

Hope shook his head, then took a step forward and, fueled by his pounding heart and burning passion, began to run.

"Bang bang bang!"

The dull knocking continued.

A few minutes later, the door opened, and Hansent, who had just gotten dressed, appeared before Hope looking dejected.

"Let's go, let's go!" Hope exhaled a breath of hot air and pulled Hansent outside.

"The port is about to open."

"We should go out there!"

……

An hour later.

Under the intense gaze of the crowd, the city port gates slowly opened.

Hope instinctively held her breath.

The next moment, he tentatively took a breath.

The breath of freedom, accompanied by a slight dampness, rushed straight into his mouth and nose.

"I can breathe... I can breathe!!" His eyes were slightly red, and his trembling lips kept repeating this sentence.

Like Hope, the citizens of the People's Union who received the first batch of slots to leave the city all had the same expression.

Anxiety, surprise, disbelief...

Complex emotions constantly assaulted everyone's senses!

At this moment, both the public and private sectors were filled with a strong impulse!

go out!

Go out and see the world!

Led by the robot, everyone lined up in an orderly fashion and walked towards the port gate.

Blue sky.

White clouds.

Clear seawater, a damp sea breeze, and the soft sound of waves.

And the land at the edge of the horizon.
