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

Lu Yongchang looked through the window towards the endless sky.

In the solar system, between the orbits of Mars and Jupiter, there is a huge asteroid belt.

asteroid belt

Among them, about 50 asteroids are bound by the gravity of the sun and Jupiter, obediently orbiting in the area of ​​2.17-3.64 astronomical units from the sun.

Among these 50 asteroids, there are a lot of mineral deposits!

It's just...according to the current technology, mining in the asteroid belt seems to be an unrealistic choice.

Perhaps, after arriving on Mars, asteroid mining technology will be completely put on the research agenda.

Equal to this technology is the research and development of weapons systems.

We can't go to Proxima Centauri at that time, and humans will continue to attack with nuclear bombs, right?

Unlike detonating a nuclear bomb in the atmosphere, because there is no atmosphere in space, after the nuclear bomb explodes, it will not produce the most lethal shock wave, but will only release a small range of high temperature, strong light and electromagnetic radiation.

This is tantamount to reducing the power of nuclear bombs countless times.

So... the weapon system of the starship is estimated to be designed from scratch.

Lu Yongchang slumped on the office chair with a blank stare, countless thoughts flooded his mind.

and many more……

Nuclear bomb?

Nuke! !

Lu Yongchang's eyes lit up, and he quickly straightened up and asked Ling, "Ling, if blasting is used for destructive mining, how long can the minerals on the earth last?"

After a short wait, Zero gave an uplifting reply.

"If the dose of explosives is not considered, the direct use of destructive mining is sufficient to meet the current construction needs."

"It's just that we don't have so many explosives at the moment."

"Who said no?" A crazy smile appeared on the corner of Lu Yongchang's mouth.

……

Office of the Speaker of Parliament.

"Chairman, Professor Lu is here."

With Zero's voice, the door of the chairman's office quietly opened.

"Yongchang?" Seeing Lu Yongchang standing at the door, Mr. Li's eyes flashed with doubt.

"Is there any news from Proxima Centauri?"

Lu Yongchang shook his head and walked into Mr. Li's office.

Then, he quickly closed the door with his hands and feet.

Seeing Lu Yongchang's unusual behavior, Mr. Li's eyes became more and more puzzled.

"Yongchang?"

As if influenced by Lu Yongchang's cautious movements, Councilor Li lowered his voice subconsciously, and asked in a low voice, "What happened?"

After closing the door, Lu Yongchang showed a slightly embarrassed smile: "Chairman, I'm here to borrow something from you."

Mr. Li: "???"

"borrow things?"

"What are you so careful about borrowing something?!"

The old man breathed a sigh of relief, leaned back, and lay on his back on the chair: "Tell me, what do you want to borrow?"

"...Nuclear bomb."

Lu Yongchang added with a strange expression: "The more the better."

"Cough cough cough!!!"

Councilor Li choked on his own saliva. While patting his chest with his hands, he straightened up from his seat, stretched out his index finger and pointed tremblingly at Lu Yongchang.

"No, what are you going to do with the nuclear bomb?!"

"This thing is not a joke!"

"Should we not use the uranium-235 and plutonium-239 in the nuclear bomb now?"

Facing Mr. Li's question, Lu Yongchang said two words lightly.

"mining."

……

The territory of the former Soviet Union.

Robots were evacuated from a mine pit in an orderly manner.

A Xuannv No. [-] slowly landed from the sky.

Inside it is loaded with a giant hydrogen bomb.

After a rough estimate, its explosive power is about 3000 million tons of TNT equivalent.

Although it is not as large as the equivalent of Big Ivan, it is already a relatively large hydrogen bomb made by humans.

After all, in the past, the nuclear fallout caused by an over-yield hydrogen bomb would have had a very serious impact on the environment.

But now, none of this is a problem!

Anyway, the earth is about to disappear. Instead of letting it be melted into a lava ball by the sun, it is better to let it play the last residual heat!

a few days later.

With a loud noise, the first laboratory of the People's Federation on the Qinghai-Tibet Plateau felt an obvious shock.

"Hiss...Zero, are you sure that such a large-yield hydrogen bomb will not affect the continental plate?"

Lu Yongchang's eyes showed a bit of fear.

After all, [Jianmu] is right next to them!

"Professor, please trust my calculations, this won't cause much impact."

Zero's virtual image responded calmly.

ps. There should only be two chapters today.

I will post four, tomorrow will definitely be three chapters.JPG

Chapter 182 The Second Photon Control Experiment

a few days later.

Inside the Renlian main laboratory.

Two huge machines lay quietly in the center of the laboratory.

Those are two single-photon control devices.

The two machines are one large and one small, and the relatively small one is a newly manufactured device.

The two devices are connected by a long and thin conduit.

As for why this happens...

Very simple.

The purpose of this photon control experiment is to verify whether two photons in an entangled state can transmit information through action at a distance.

Unlike the first experiment, this experiment required two photons in an entangled state.

Therefore, the second single-photon control facility directly removes the original single-photon fabrication facility.

At that point, both photons will all be manufactured by the first device.

……

Lu Yongchang stood in front of a machine with a solemn expression.

"Professor Lu, can the experiment start?"

Tang Wenshan's voice came from the side.

Lu Yongchang thought for a moment, and after confirming that there were no mistakes, he nodded slightly.

"Let's start the experiment!"

As he spoke, he stretched out his hand to press the switch of the huge machine in front of him.

A slight tremor came through the floor.

The photon manufacturing instrument in the single photon control device in front of Lu Yongchang began to operate.

As the light turns green, the two entangled photons pass through the conduit into the single-photon control devices on the left and right.

"Zero, first control the number one photon."

Lu Yongchang said in a deep voice.

"Received." The moment Zero's voice sounded, there was a slight buzzing sound from the single-photon control device in front of Lu Yongchang.

As for Tang Wenshan, he was staring at the monitor of another control device, for fear of missing any small changes.

"..."

In the laboratory, everyone held their breath.

I am afraid that my weak breathing will affect the two "fragile" photons in the huge instrument in front of me.

The waiting time of a few seconds seemed like a century to all the researchers present!

In the silent laboratory, only the slight humming from the two single-photon control devices remained.

"……changed!"

Suddenly, Tang Wenshan's eyes showed ecstasy, and he shouted loudly: "The state of No. [-] photon has changed!"

At this moment, even Lu Yongchang could not hold his breath.

Following in the footsteps of a group of researchers, he ran towards the second single-photon control device.

Looking at the rapidly changing numbers and curves on the display, Lu Yongchang blushed slightly, and shouted loudly to the camera on the side: "Zero?!"

"Professor, 100 state change experiments have been carried out so far, and the No. [-] photon has produced corresponding changes."

"Do you want to continue to change the state of No. [-] photon?"

Lu Yongchang's eyes became more joyful: "Continue, follow the target plan."

"Received, a total of 30 experiments, estimated to take [-] minutes."

Lu Yongchang took a deep breath to suppress the ecstasy in his heart.

Not quite a success.

He needs more experimental samples!

……

After half an hour.

"Professor, the No. [-] photon experiment has been completed, a total of [-] state change experiments, and No. [-] photon has observed corresponding changes."

Zero's voice sounded in the quiet laboratory.

In the next second, a burst of warm applause followed!

Every researcher's face is filled with excited smiles.

"Zero, start the experiment on Photon No. [-]!"

In addition to being excited, Lu Yongchang did not forget to issue a second command to Zero.

……

The second photon control experiment was a complete success, and most of the technology accumulation of quantum long-distance communication technology has been completed.

Now, the last difficulty in realizing quantum long-distance communication falls on Tang Wenshan.
