Cataclysmic Era: I can unlock the tech tree

Hope's utterly terrified voice made Hansent freeze in place.

The water in the water is rising?

Are you kidding me?

Although City One is built along the water, it is still hundreds of kilometers away from the nearest body of water.

In addition, with some hills of varying heights along the way blocking the view, how could the camera possibly capture the scene on the other side of the water?

Filled with doubt, Hansent subconsciously turned his head to look at the small holographic projection in front of Hope.

That was a small holographic image from Hope Watch; in terms of image quality and visual experience, it naturally couldn't compare to the giant holographic image in the square.

In addition, the strong winds and heavy rain made the small holographic image appear very blurry.

Even so, Hansent immediately recognized the location in the image.

"This is...Area A3?"

He frowned and asked in a low voice.

Hope quickly nodded: "Yes, this is the camera footage from area A3."

"……hiss!!!"

Upon receiving confirmation, Hansent gasped sharply!

What happened to Area A3?!

"Isn't that a hilly area over there?" Hansent stared at the screen, speechless, muttering to himself, "How did it turn into... a lake?!"

The A3 region of Dawn Star, adjacent to the A1 and A2 plains, is a hilly area, close to water bodies, and relatively low in elevation.

But now, the scene in the holographic image is a turbulent lake dotted with islands!

No, perhaps it shouldn't be called a lake.

If we include the waters further out, what lies before them should be the first ocean on Dawn Star.

Under the blows of the unique storms of Dawn Star, towering waves surged one after another on the ocean!

These giant waves, driven by the gale-force winds, crashed violently against the islands that emerged from the water.

Visibly, the islands, mostly composed of weathered rock, are rapidly shrinking in size under the impact of the giant waves.

Clearly, Hansent was having some difficulty accepting this ultra-accelerated version of the dramatic evolution before him.

"Are you... sure this is area A3?"

"You didn't pull up the camera footage for the A4 area, did you?"

Area A4, adjacent to Area A3, is the area closest to the water, with a lower elevation and a typical coastal landscape.

Hansent was more inclined to believe that this was footage from the camera in area A4.

Faced with Hansent's questioning, Hope remained silent for a moment, then raised her finger and pointed to several metallic-looking rocks.

"See that?"

Under the constant pounding of the waves, the fragile weathered rock on the surface of the reef has almost completely disappeared, exposing the metal veins within.

"This is the highest peak in the Andrews Mountains."

"If I remember correctly, there are quite a few copper mines in this area, and the mineral prospector is Andrew from Hong Fan's team."

Hansent's lips twitched slightly.

After this reminder, he could vaguely make out the shape of the reef.

"As for area A4..." Hope reached out and manipulated her wristwatch, switching to the holographic image.

"We're now in the underwater world."

The holographic projection flickered for a moment, then projected a "peaceful and tranquil" scene.

Hansent: "...The camera quality is really good."

He sighed weakly.

Hope shrugged and switched the holographic image back to area A3.

In just a few minutes, the distance between the sea surface and the camera shrank again.

"Based on the current rainfall, it is estimated that the A3 area will be completely flooded soon."

A hint of worry flashed in Hope's eyes: "Then, it'll be City One's turn."

"I wonder if the dam can hold..."

……

Headquarters of the Chinese Academy of Sciences, Command Center.

"Warning! Yellow flood warning!"

"The water level is expected to rise to the guaranteed level."

As the electronic synthesized sound of "Zero" rang out, dozens of areas marked in red appeared on the giant holographic projection directly in front of them.

Fang Xu looked at the holographic projection with concern: "Yongchang, the situation is a bit beyond expectations."

"The water level is rising too rapidly, our dikes..."

Fang Xu didn't continue.

But everyone in the command center was aware of the consequences of this.

Once the water level rises above the dam, City One will become the first underwater city in human history.

Although City One is well-sealed and its design is sufficient to withstand this not-so-strong water pressure.

but!

City ports are all built near the ground!

Once it becomes an underwater city, the port will definitely be unable to be opened.

They may have to expend considerable effort to move all the supplies.

Lü Yongchang was naturally aware of this.

He frowned as he looked at the constantly changing numbers in the holographic projection.

"It shouldn't be a big problem."

"In zero-scale simulations, the amount of water brought by Nero is insufficient to submerge our dams."

"Just wait patiently."

Despite saying that, a hint of anxiety couldn't be hidden on his face.

……

One day later.

The torrential rain that swept across the entire planet gradually subsided.

The melting of the icy comet absorbed a large amount of heat, and the surface temperature of Dawn also dropped significantly.

Looking at the slowly rising average atmospheric temperature curve, Lü Yongchang breathed a slight sigh of relief.

Fortunately, thanks to the combined efforts of Gliese 555 and the planetary climate control satellites, the surface temperature of Dawn has not yet dropped below freezing.

Of course, the main contributor is the Gliese 555.

Compared to the light and heat from the stars, the energy provided by humankind is but a drop in the ocean.

Therefore, all climate control satellites can do is provide guidance based on the existing foundation.

If Dawn doesn't experience periodic global storms, even if human climate control satellites were to increase their power several times over, they probably wouldn't be able to have much impact on Dawn's climate.

Lu Yongchang glanced at the sensor data in the holographic projection and a long-lost relaxed smile appeared on his face.

The results are basically the same as the calculated results.

The dam successfully held back the floodwaters.

only……

Humanity's six surface cities now resemble six isolated islands in a vast ocean.

Looking at the footage transmitted from the camera, Lü Yongchang shook his head helplessly.

"Yongchang, what's next?" Looking at the vast, shimmering sea surrounding City One, Fang Xu's lips twitched, and he asked in a low voice, "Build a new enclosed city?"

Lu Yongchang pondered for a moment, then slowly shook his head.

"No."

"This time, we'll build an open city."

"Once the city is completed, the environmental transformation of Dawn Star will probably be basically finished as well."

"At that time, humans who awaken from hibernation can live directly on the terraformed Dawn Star."

At this point, Lü Yongchang paused slightly.

He turned his head to look at the camera next to him.

"Zero, prepare to dispatch a swarm of drones for high-altitude reconnaissance of the surface of Dawn Star!"

"The captured footage is synchronized to all holographic terminals."

Just as described in the Bible,

To test whether the floodwaters outside had receded, Noah released doves.

now,

In order to observe the effects of the massive flood caused by Comet Nero, Lü Yongchang ordered the release of a swarm of drones.
