“How long has it been?”

The scientist with the flashlight asked.

He’s still trying to send light signals.

However, it can be seen that his arm is twisting unconsciously.

The expression on the face is also not very good-looking.

Others look at the time.

“It’s almost half an hour.”

In the past half hour, Sun Shangwei continued to transmit those two words through a flashlight.

Hello…… Hello…… Hello….

The hand that pressed the flashlight was sore.

My arm ached even more.

It looks like the light signal is useless either.

Everyone had disappointed expressions.

As normal.

If the aliens really saw the light signals they were sending.

Even half an hour is not enough for them to decipher the content of the signal.

At least it’s okay to write them back.

There are even extreme thoughts in their minds.

“If I were to say, it would be better to just use plan one, drag the water droplet out of the air, disassemble it, at least a few techniques we can figure out.”

In the conference room, people began to discuss in whispers.

This extreme thinking is not new.

From the beginning, there were individuals who agreed with this approach.

It’s just that most people disagree.

The second approach was eventually taken.

Communication is now blocked.

Those extreme scientists again proposed method one.

Who knows if there are aliens in the droplets, and there is no learning at all.

“What technology do you think we can get by dismantling the water droplet?” Someone asked rhetorically.

“There are at least two, one is absolute zero cryogenic technology, and the other is anti-gravity technology suspended in the air.

I believe that the principle of these two technologies is inside the water droplet.

Just take it apart.

Glance. ”

The person did not say anything about the technology that reflects electromagnetic waves one hundred percent.

As a scientist, he knew that water droplets reflected 100% of electromagnetic waves.

Most of it has to do with the material on its surface.

Materials are not something that can be made by giving you some samples.

Like the B2 stealth bomber of the Eagle Country.

Even if someone brings the coating material above to you.

No one dares to say that it will definitely be replicated.

The study of materials is very complex.

There are many variables that determine the final properties of a material.

The type of elements added, the proportion, temperature, time, and even humidity, vibration can become decisive variables.

“You don’t talk about the stealth ability of water drops, do you think that even if we get this material, it will be difficult to copy it in a short time?”

So do you think we can replicate the technology inside the water droplet?

Have you ever thought about how much material is used inside the water droplets that we cannot understand? ”

“This…”

Radical scientists fell silent.

The other party is right.

It was he who thought the problem too simply.

The material on the surface of the water droplet that reflects 100% of electromagnetic waves is obvious.

Anyone can see it.

It has anti-gravity ability, as well as the ability to maintain absolute zero.

The technology needed is definitely hidden inside.

This is also what everyone can think of.

It’s just that he missed one point.

Anti-gravity technology, as well as special materials required for absolute zero.

I’m afraid it’s much more than a material that reflects 100% electromagnetic waves.

Violent dismantling will definitely bring certain inspiration to human science and technology.

It can point in at least one direction.

The internal physical structure will be exposed to everyone after dismantling.

But the cost of doing so is too great.

If this angers an alien civilization, it will be a devastating disaster for the entire human race.

When the current situation is unclear, there must be no such thinking.

A foreigner’s statement is actually true.

We Dragon Kingdom people are not qualified to make decisions for the life and death of all mankind.

“Can’t disassemble, what now?”

The discussion in the conference room was louder.

A few people spontaneously became a group.

They are all talking about how to deal with water droplets.

All three communication methods in nature have been tried.

None of them worked.

Now they lack a direction.

No one knows if there are really aliens in the droplets.

Is it the wrong direction to get in touch with aliens?

Air.

“I don’t think the water drops should answer, forget it.”

Someone has already given up.

If the drops could answer, they would have answered long ago.

“Put it down.”

Sun Shangwei sighed and finally lowered his arm.

My right arm ached.

His efforts for half an hour are not at all useless.

At least it proves that aliens do not respond to light signals.

“What’s next?” Zhang Hongbo asked.

When they came up, they laid down the order of the experiments.

Since contacting the aliens failed.

It’s time to move on to the next experimental project.

“The next experiment is the study of surface materials of water droplets.”

By this time, someone had already moved a huge machine out of the plane.

This machine is the biggest machine they brought this time.

A million-fold electron tunneling microscope.

Study the material composition of water droplets through physical means.

Just when everyone set up the microscope.

“There is light, you see the light on the droplets!”

Sun Shangwei suddenly saw that light appeared on the mirror surface of the water droplet.

Everyone looked beyond the droplets.

It’s not enough to set up a microscope.

“The water drop answered, quickly write it down, quickly!”

Zhang Hongbo shouted.

His heart was pounding.

Rub

and rub….

Live broadcast in the conference room.

Countless scientists stood up.

Eyes stared dead at the screen.

You can clearly see that the water droplets are flashing!

This flickering of light is not cluttered.

Instead, it flickers in a rhythm that everyone is familiar with.

That’s right!

It’s Morse coding.

This shows that the water drop really answered!

Zhang Heng also stood up.

Even if he was firm in his heart, he was a little excited at this time.

Did the aliens really answer?

The first call between humans and aliens!

He didn’t know if it was good or bad for humans.

There has been a huge turning point in human history.

He is a witness.

At the same time, he also knows that the answer of the water drop will make the pressure of the above face other countries even greater.

Whether it was a coincidence that the water droplets appeared in the Dragon Kingdom no one knew.

But the counterpart to the alien civilization is the entire human race, not just the dragon countrymen.

This is obvious.

Zhang Heng could only hope that the top was on top for a while.

Give us scientists more time.

……

The live broadcast rooms of major anchors also boiled at this moment.

“Lying groove, do you see it, the water droplets are flashing!”

“What does this mean, it answers!!!”

“Did anyone who understands Morse code, what is the water drop saying?”

“This is the first communication between humans and alien civilizations.”

“What is it talking about?”

The whole country was shocked.

I thought it was impossible for the water drop to give an answer.

Unexpectedly, when everyone was desperate.

He really gave an answer.

“Bright, bright, bright, bright, long, bright, long, bright, dark, bright, bright, long, bright, bright, bright, dark…”

The recorder’s hands were shaking.

He quickly jot down all the reply codes in his notebook.

The scientists around them all put down their work.

One moment look at the flashing droplets.

After a while, I looked at the notebook in the recorder’s hand.

It’s like a child who is about to get a toy he has wanted for a long time.

No one can remain calm.

There are half a minute before and after.

The drops returned to calm.

“What does it say?”

The scientists immediately moved forward, wondering what the aliens had said to everyone.

“He said, ‘Hello.'”

The codebreakers could see the meaning of this Morse code almost at a glance.
