Chapter 67: Humans, have you really contacted me?

It is clearly early spring, the season with birds singing and flowers blooming, but it seems like we have returned to the cold winter.

This might be the so-called late spring cold snap. Lu Yuan always felt cold all over. He just wanted to go home quickly and warm himself around the fire.

He discovered something was wrong with himself and sneered, "Comfort and laziness are indeed the enemies of civilization. It took less than a year for the strongest civilization of mankind, the 18th Civilization, to degenerate from a terrifying upright ape that could kill a salamander alone to a stray dog ​​that trembles at the sight of a monster."

"Everyone laughs at the Meda civilization, but everyone is the Meda civilization."

Lu Yuan was a little scared, but also slightly excited, and his heart was beating strongly.

He was frightened when he was stared at by the monster.

This made his adrenaline surge wildly.

Not knowing what was in his mind, Lu Yuan laughed softly. He himself didn't know why he laughed, and couldn't describe his mindset.

The old wolf following behind sniffed and found that his master had undergone inexplicable changes.

This mental state was a bit similar to when the owner was hunting salamanders, making it feel inexplicably fearful.

The old wolf shook his fur and nibbled the spring grass. He was always carefree.

Lu Yuan smiled as he played with the outstanding dagger. The stones under his feet made a clattering sound.

While I was thinking about this, we finally arrived at the shelter.

He piled the firewood he picked up in the utility room.

Even though he encountered some risks, he still subconsciously picked up a lot of trash.

There's nothing I can do about it. I'm used to it. Going home empty-handed is not my style.

"Buzz——" Just as he turned around and was about to leave, the big iron ball actually vibrated! !

"Hey, are you sick again?"

In fact, after so long, Lu Yuan gradually lost interest in this big metal ball and only used it as a clock.

He still needs to know what time it is.

Just when I was about to turn it off, the big iron ball made a very strange alarm sound: "Déng~!~!"

Lu Yuan was stunned for a moment.

This sound is weird...

It's really weird! It's like the sound of the little man jumping in the Super Mario game.

Because the sound was too strange, Lu Yuan's hand, which was halfway to turn off the phone, suddenly froze in place.

He frowned and waited for a long time.

The hope that had been lost long ago slowly emerged from my heart.

"What's going on?"

After about ten minutes, the big metal ball made a "ding-ding-ding" sound again.

It's a bit crisp, a bit like a telephone ringtone, but not quite standard.

He waited for a long time again, looking left and right at the metal ball.

About half an hour.

The metal ball made a "beeping" sound, which was very similar to the sound of eating coins in the Super Mario game! If it happened once, it would be a coincidence; twice, it might also be a coincidence; but three times, it was inevitable.

Lu Yuan's pupils dilated, and he thought of a possibility, and his body began to heat up: "What's going on?"

"Human, have you really contacted me?"

…

…

"He finally understood what we wanted to say!"

"He's not closed!"

Seeing that Lu Yuan did not close the big iron ball, everyone in the institute cheered in surprise!

The essence of sound is actually waves.

The waveforms that can be emitted by the alarm vibration channel are limited, only triangle waves and square waves, and the sounds that can be fitted are also limited.

The frequency of vibration is also limited, and can only send 1 to 2 syllables, so it is not realistic to send music or something like that.

Scientists conducted hundreds and thousands of attempts before they were able to use these two sound waves to create the sound of a "Super Mario" jumping.

After all, that sound is so classic. With a "déng~~" sound, the little man jumped up on the TV with his butt raised.

It's very visual! It's something that every young person in the 21st century has heard.

Moreover, it is definitely a man-made sound made by humans! It hardly exists in nature.

What's more, the staff of Yunhai City even conducted a special investigation and found out that Lu Yuan had a game console at home, which contained Mario games. It was absolutely guaranteed that Lu Yuan had heard of it!

The message conveyed by this sound is: it is a signal from humans, so don't turn off your phone! Using just one sound, so much information is conveyed. In addition, the hardware of alien civilizations is different from that of humans, so it really took a lot of effort to make this sound.

Next, the sound of a telephone ringing and the sound of eating gold coins were transmitted, further reinforcing the message of "signals sent by humans."

There is no mistake in the poem, post, content, and read the book on 6, 9, and bar!

In this way, Lu Yuan can know that he has established contact with humans.

…

"Why do humans also have these metal spheres? How is it possible..."

"Why is there this sound? Is it really contacting me?"

Lu Yuan was suspicious and kept touching the metal ball.

His heart was burning with enthusiasm, but now he was somewhat anxious and worried - because he had experienced too many difficulties, and it was not a bad thing to lower his expectations, but if expectations were too high, it would be easy to be disappointed.

At this moment, Lu Yuan suddenly had an idea and thought of a document he had read before: 8 years ago (8 years before the Meda civilization came to Pangu Continent), a meteorite fell from the sky, and the Meda civilization ushered in a supernatural era...

There are similar news reports on Earth, but 10 years ago, a meteorite fell from the sky, ushering in a supernatural era, and all kinds of super-powered people appeared like mushrooms after rain.

At first, Lu Yuan didn’t think too much about it and thought that “meteorite falling from the sky” was an inevitable phenomenon before the opening of Pangu Continent.

Now, in a flash, all these clues were connected together in my mind.

What kind of meteorite is this? ! It’s actually this big metal ball that fell from the sky!!

It’s just that the government concealed the news and conducted research secretly... After all, which country would announce the existence of aliens?

Even if there are some comments on the Internet, they are just treated as rumors.

No one believes it.

So, humans actually have this kind of metal sphere too, and they are actually trying to contact me! !

"That's right."

Thinking of this possibility, Lu Yuan jumped up from the ground in shock, his heart beating wildly.

The hairs on his body were trembling, and he stood in front of a crystal screen with a fiery heart, shouting: "Humans, can you see it?"

"Hurry up and contact human civilization. The number is...what is the number...7812HSKKJ-1 to 7812HSKKJ-17!!"

"If you can hear it, please make that sound like a gold coin again!"

Take a deep breath. Take a deep breath.

The waiting time is anxious. Time passes slowly on the human side, so we have to wait.

The ups and downs of mood are more likely to cause people to become anxious.

Lu Yuan felt that his mood at the moment was just like the second before the college entrance examination results were released. He always wanted to perform exceptionally well, but the actual results... Lu's college entrance examination results were not ideal.

"Even if we can't get in touch, I can accept that."

"Please don't contact me. It's just a piece of junk that can only tell time! All other functions are useless. It must be a scam."

A Yuan kept feeding himself poisonous milk.
