Chapter 67 Humans, have you really contacted me?


    It is clearly the environment of early spring, and the season of birds singing and flowers smelling, it seems to be back in the cold winter.


    This may be the so-called late spring cold. Lu Yuan always felt cold all over his body. He just wanted to go home quickly and cook around the fire.


    He discovered something wrong with him and smiled: "Enjoy and laziness are indeed the enemy of civilization. The strongest civilization of our human beings, the 18th civilization, took less than a year to go from a terrifying upright ape who killed the salamander to a stray dog ??who trembled when he saw monsters."


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


    Lu Yuan was a little scared and faintly excited, and his heart was beating vigorously.


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


    This made his adrenaline surge wildly.


    Not knowing what kind of mentality was, Lu Yuan laughed softly. He himself didn''t know why he laughed, and he couldn''t describe this mentality.


    The old wolf following behind him sniffed his nose and found that his master had changed inexplicably.


    This mental state is a bit similar to the owner''s original hunting of the salamander, which makes it feel inexplicably afraid.


    The old wolf shook the hair on his body and gnawed the spring turf. It was always carefree.


    Lu Yuan laughed while playing with the excellence dagger, and the stones under his feet were clattering.


    As I thought about it, the shelter finally arrived.


    Pile the firewood I picked up casually into the utility room.


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


    There is no way, I''m used to it, it''s not my own style to go home empty-handed.


    "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, but was just used as a clock.


    He still needs to know what time it is now.


    Just as I wanted to turn it off, the big iron ball actually emitted a very strange alarm: "déng~!~!"


    Lu Yuan was stunned for a moment.


    This sound is very strange...


    It’s really strange!


    It''s like the sound of a villain jumping in the Super Mario game.


    Because the sound was too strange, Lu Yuan''s hand that was halfway through his attempt to turn off the phone suddenly froze.


    He frowned and waited for a long time.


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


    "What''s going on?"


    After about ten minutes, the big metal ball once again made a "drip ring" sound.


    A little crisp, a bit like a phone ringtone, but not very standard.


    He waited for a long time and looked around at the metal ball.


    About half an hour.


    The metal ball made a "drip ring" sound, which looked like the sound of eating gold coins in the Super Mario game!


    If once is a coincidence; twice may also be a coincidence; but three times is an inevitable.


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


    "Human, have you really contacted me?"


    …


    …


    "He finally knows what we want to express!"


    "He didn''t close!"


    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 triangular 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 unlikely to be realistic to send music or something.


    Scientists made hundreds or thousands of attempts to create a "super Mario" jumping sound using these two sound waves.


    After all, the sound was so classic. With a "déng~~", the little man raised his **** and jumped up on the TV.


    Full of picture!


    It’s a young man in the 21st century who has heard of it.


    Moreover, it is definitely made by humans, artificial sound! It almost does not exist in nature.


    Even the staff of Yunhai City even specifically investigated that Lu Yuan had a game console at home, and there was Mario Game inside. It is absolutely guaranteed that Lu Yuan had heard of it!


    And the message conveyed by this sound is: It is humans sending a signal, don’t turn off the phone!


    Using one sound, it can convey so much information. In addition, the hardware of the alien civilization''s device is different from that of humans. It really took a lot of effort to make this sound.


    Next, the phone ringtone and the sound of eating gold coins were transmitted, which once again strengthened the message "signal from humans".


    In this way, Lu Yuan can know that he has been connected with humans.


    …


    "Why do humans also have this kind of metal ball? How is it possible..."


    "Why is there such a voice? Are you really contacting me?"


    Lu Yuan was suspicious and touched the metal ball.


    His heart is hot, but now things are getting a little worried about gains and losses - because he has experienced too many difficulties, lowering expectations is not a bad thing, and too high expectations are easy to lose.


    At this moment, Lu Yuan suddenly had a flash of inspiration and thought of a document he had read: since 8 years ago (8 years ago when the Meda civilization came to Pangu Continent), a meteorite fell from the sky, and the Meda civilization opened the supernatural era...


    There are similar news reports on the earth, but the earth was 10 years ago. Meteorites fell from the sky, opening up the supernatural era. Various superpowers appeared like mushrooms after a rain.


    Lu Yuan didn''t think too much at the beginning, and he thought that "meteorite falling from the sky" was an inevitable phenomenon before the opening of Pangu Continent.


    Now, these clues are connected in my mind.


    What kind of meteorites fell from the sky? !


    This kind of metal ball is actually falling from the sky!


    It’s just that the government concealed the news and secretly studied it... After all, there is such a thing that aliens have, which country will publicly advertise it?


    Even if there are some remarks on the Internet, they are just taken as rumors.


    No one believed it.


    So, there are actually such metal **** on humans, and humans are actually contacting themselves!


    “That’s right.”


    Thinking of this possibility, Lu Yuan was so shocked that he jumped from the ground, his heart beating wildly.


    His whole body''s hair was trembling, and he stood in front of a crystal screen in a hot mood, and shouted: "Human, can you see it?"


    "Come on human civilization quickly, the number is...what is the number...7812HSKKJ-1 to 7812HSKKJ-17!"


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


    Take a deep breath, take a deep breath.


    The waiting time is anxious. Time passes slowly over humans, so you have to wait.


    The ups and downs of moods are more likely to cause people''s anxiety.


    Lu Yuan felt that his mood was like the second before the college entrance examination scores. He always thought that he could perform well, but his actual results... Ah Lu''s college entrance examination scores were not ideal.


    “Even if you can’t contact us, it’s acceptable.”


    "If you want to do it, don''t contact me. It''s just a garbage product that can only look at time! All other functions have been scrapped, and it must have lie to me."


    A Yuan kept feeding himself poisonous milk.
