It's reasonable for me to have a two-way foil for a second-level civilization, right?

Under everyone's watchful eyes, the port gate slowly closed.

"The "Noah's Ark" project is officially launched."

The first step of the Dawn Star surface environment transformation plan, "Noah's Ark".

Similar to Noah's Ark in the Bible, humans at this time hid in six surface cities in order to avoid the next global heavy rain.

When the rain ends, the flood subsides, and the human beings who walk out of the surface city will get a brand new home!

Chapter 450 Detonation

Earth calendar, July 2384, 7.

23:30:00

Time passed little by little.

Inside the six surface cities.

Hundreds of millions of human beings either stayed at home or gathered in squares and streets.

Not any loud noises.

Everyone held their breath and quietly looked at the holographic projections in front of them, large or small.

In the picture, the red countdown is beating extremely firmly.

The last three 10 minute countdowns.

Outside the city, the atmosphere on Dawn Star was as dry as ever.

Under the control of the circumplanetary climate control satellite, the high-risk area numbered X once again blew a super storm.

The A1 plain is breezy, and the light from Gliese 555 evenly spreads on the yellow-brown soil, bringing some warmth to this super-Earth.

Quiet and peaceful.

But if you look up at the blue-purple sky, you will see a horrifying scene!

A huge black sphere is slowly moving across the sky.

That's comet Nero wrapped in a carbon nanotube black cloth!

Not far from the black sphere, there are more than a hundred small dots shining with light.

That is the light from the Hall thruster at the tail of the [Glutton] material transport ship!

A few hours ago, with the gravitational force of Dawn Star and the joint efforts of the [Glutton] material transport ship, the comet Nero had already entered the predetermined orbit.

Currently, the [Glutton] material transport ship is doing its final deceleration work.

As the flight speed decreases, Nero's orbital altitude will continue to decrease.

until it falls into the atmosphere.

The black cloth on its surface will also be "untied" just before falling into the atmosphere.

……

"Nero has reached the predetermined speed!"

"Get ready to untie the 'net bag'!"

Lu Yongchang's steady voice sounded in the command hall of the headquarters of the Academy of Sciences.

In the huge holographic projection directly in front of him, Nero's flight speed kept decreasing, and the scheduled flight trajectory became a parabola.

"Warning!" Zero's electronically synthesized voice came from the speaker, "Nero will touch the atmosphere of Dawn Star in 15 minutes!"

A gleam flashed in Lu Yongchang's eyes, and he gave the order without hesitation.

"Untie the 'net bag'!"

almost the same moment.

"Boom! Boom! Boom!"

On the surface of Nero outside the atmosphere, several explosions occurred!

The power of these explosions is so small that they can only break the black "net bag" made of carbon nanotube material.

After the net bag was untied, the [Glutton] material storage ships each dragged their own fragments and left quickly.

Of course, accidental damage was unavoidable during the explosion - part of the ice on the surface of Nero was blasted into space by the explosives.

These finely divided ice crystals form a large white "cloud" above the atmosphere.

Nero, who had just escaped from the net bag, disappeared into the "cloud" that shone brightly in the sun in an instant.

The scene that happened outside the atmosphere was clearly recorded by ultra-high-definition cameras and displayed in all holographic projections in real time.

……

The moment the black net bag was untied, Hope subconsciously held his breath.

Not only him, but everyone around him reacted the same way.

00:14:30

The bright red countdown numbers were still beating unhurriedly.

But the picture sent back by the high-definition camera showed no movement at all.

"It won't be stuck..."

"Are you kidding, this thing can also be stuck?"

At such a critical juncture, waiting for a full 30 seconds caused a little commotion in the originally quiet crowd.

"Out!"

A high-pitched voice sounded from a certain corner of the square!

All eyes are on the huge holographic projection ahead!

really!

Nero, rushed out of the white clouds with unrivaled momentum!

At this moment, in front of hundreds of millions of human beings, it revealed its long-hidden true face.

A huge, dirty white puck.

Although the appearance is not very good-looking, there is no look of disgust on anyone's face.

This is the cornerstone of building a super earth!

"God……"

Hope stared straight at the holographic projection in front of him, and muttered to himself: "Hancent, tell me, if this comet directly hits the surface of Dawn Star..."

"Are we extinct like the dinosaurs?"

Hansen rolled his eyes angrily.

"What are you kidding?"

"Where do you eat when the People's Federation Fleet is there?"

Even though he said that, there was still a little panic in Hansent's eyes.

……

00:00:30

The last 30 seconds.

At the headquarters of the People's Federation of Sciences in City No. [-], a piercing siren sounded in the command hall!

"warn!"

"The target will touch the atmosphere of Dawn Star in 30 seconds!"

Lu Yongchang looked serious, and reached out to operate the small holographic projection in front of him.

"Attention all units."

"Prepare for the detonation of a high-yield hydrogen bomb!"

As soon as the words fell, Nero cut into the atmosphere of Dawn Star with a graceful cutting angle.

Then, bright flames appeared in front of the white Nero.

That is the phenomenon caused by Nero's intense friction with the dense atmosphere of Dawn Star after entering the atmosphere!

The heat generated by the friction quickly melted the giant icy comet.

But with a diameter of 600 kilometers, it is doomed that it cannot be completely melted in such a short period of time!

At least, it can't melt naturally before it hits the ground.

then……

When Nero's height dropped to a certain level, Lu Yongchang reached out and pressed the virtual button on the holographic projection in front of him.

"Detonation!"

……

The countdown has already reached zero.

Seeing the scene where the huge Nero hit the ground with a monstrous momentum, everyone's face showed instinctive fear.

No matter who it was, even Hope and Hansent, the devastating scene of the meteorite hitting the ground flashed through their minds.

But next second.

Mutation!

boom! ! !

Under everyone's gaze, an extremely strong shock gushed out from Nero!

In an instant, this giant ice comet with a diameter of 600 kilometers turned into several large fragments.

These fragments swirled in the air, flying in all directions like a goddess scattering flowers!

In the blue-purple sky of Dawn Star, a picture like a meteor shower suddenly appeared.

The crowd suddenly fell silent.

In the next second, deafening cheers came from all directions!

"It's a super-yield hydrogen bomb!" Hope whispered.

While speaking, he clenched his fists tightly, his face full of excitement.

Even if it is a giant comet with a diameter of 600 kilometers, under human weapons, it can only end up in pieces!

Like Hope, everyone in the city has more or less excitement and pride in their eyes.

This is today's human civilization!

This is the power in the hands of humans today!

Human beings are no longer afraid of any natural disasters on the planet, on the contrary, human beings can use these natural disasters to transform the planet!

Chapter 451

Different from the cheers in the six surface cities, the headquarters of the People's Federation of Sciences is filled with tension.

Every scientific researcher pays close attention to the holographic interface in front of him, for fear of missing any data.

the reason is simple.

After the super-yield nuclear bomb detonated, Nero produced super-large-scale debris.

Smaller pieces don't require much attention.

In the process of falling, they will naturally melt.

What needs attention is those fragments that are too large.

Although after rigorous calculations, the Academy of Sciences has chosen the relatively safest blasting method.

However, the first explosion still produced thousands of medium and large comet fragments that could threaten the surface of Dawn Star.

Among them are five super-large fragments with a diameter of more than [-] kilometers!
