Tesla, with a mustache, appears in virtual reality, braving the pouring rain into the lab, activating the generator and checking his equipment one by one. Tesla's expression was thoughtful, and finally he walked to the front of the console, pressed one hand to the button, and after a moment's pause, Tesla pressed the button.

The perspective in virtual reality is very strange, and different scenes are mixed together, as if time and space are intertwined. Just outside Tesla's lab, the elliptical antenna atop Wordencliffe Tower suddenly lit up, and lightning flashed in the middle of it, illuminating the sky of Long Island with a glow that almost illuminated the entire Long Island sky. A bolt of lightning rose from the middle of the antenna, splitting the dome of Long Island in half, and in an instant, the lightning disappeared again, and at the moment when the sky had just returned to darkness, lightning bolts spread out from Wordencliffe Tower, and combined with the lightning that fell from the zenith clouds, tearing the sky into pieces.

A figure scurried through the darkness, his face blurred by the heavy rain, and he seemed to be familiar with Tesla's laboratory, and soon found the main entrance and broke in.

"Clifford, how are you?" Tesla seemed to be very familiar with the footsteps of the comer, and he couldn't keep his head up, and he was still desperately pressing the control switch of Worden Creverta.

The man named Clifford took off his rain-soaked hat, took off his raincoat, revealed the shiny logo on his uniform, and said to Tesla while stomping the rain on his boots, "Mr. Tesla, the board of directors has asked me to inform you that you no longer have the right to use the equipment here, and please stop the experiment at Worden Clifford Tower immediately!" ”

"What! Even Westinghouse is going to abandon me! Tesla slapped the switch button fiercely, turned his head and said angrily to Clifford.

Virtual reality now places Clifford's visitor in the center of the image. Liu Weiping's search process was running for a while, and he compared this Clifford with the Clifford face he saw in Los Angeles, and although it was determined that it was not the same person, the similarity was almost 80%.

Park Zhengyu seemed to understand Liu Weiping's thoughts, "Professor, you don't have to guess, he is the grandfather of the boss of Zephyr Animation, Old Clifford." ”

Liu Weiping was shocked, and he even suspected that his atomic memory was still in a state of invasion. Just as he kept scanning for anomalous programs, a scene surprised them in the virtual reality image on the other side of the glass.

An unnamed machine next to Tesla began to flash its tubes, and a mechanical device manipulated a slender needle to vibrate up and down on a piece of smoked glass, recording an irregular waveform.

"Mr. Tesla, your radio receiver is working!" Old Clifford also saw the abnormality around Tesla and shouted excitedly.

"My radio patents can bring a lot of money to the company, but why are you doing this to me!" Tesla was clearly still in a state of emotion, but he immediately put down the transmit button of Wodenclifforta, ran to the radio receiver, and he bent down and carefully looked at the treasure that had brought him great fame, his eyes staring at the smoked glass for a long time, and his brow furrowed.

"That's a signal from the Tunguska ship!" Liu Weiping outside the glass exclaimed, he couldn't be more familiar with this waveform, he received this residual signal at the bottom of Lake Baikal and went to Komsomolsk to successfully decipher the information that it was the Markov equation chain, and since then he has stored the various signal expressions of the Markov equation chain in his atomic memory, and saw that Tesla in virtual reality also received the same signal, Liu Weiping couldn't help it, "It turns out that Markov is not the only one who has obtained the secret of the Tunguska spacecraft!" ”

"The professor's data storage is really large enough, yes, Tesla received the signal from the Tunguska spacecraft." Park Jung-woo said on the side, "It's a pity that all his energy at this time is in Woden Creverta." The virtual reality stopped as Park Jung-woo's voice stopped, and the nebula image of the spiral arm structure was restored on the glass side.

Han Bingbin seemed to forget that he was in a dangerous situation, and asked Park Zhengyu, "What happened later?" ”

"Even if Tesla studied it carefully, he would not have deciphered this wave, because this is the alpha waveform of the human brain, which will not be recognized by Nazi scientists until nearly thirty years later, and Markov's brain happened to be thinking about the same statistical problems in the signal back then, and his brain resonated with this alpha wave." Park Jung-woo replied, "But the record on the smoked glass fell into the hands of Westinghouse Electric and was shelved. ”

"That's it, what does it have to do with you finding the Tunguska ship?" Han Bingbin asked.

"Of course it's not over! After the second stop, the Allies captured a group of German brainwave scientists, they came to the United States and began to receive funding to continue to study brainwaves, but because there was no progress, it was disbanded within two years, one of them went to Westinghouse Electric to work, by chance, he met the grandson of the old Clifford, that is, Professor Liu, the Clifford you know, from him saw the signal on the smoked glass, the German scientist recognized at a glance that this was the alpha waveform of the human brain, this astonishing discovery was immediately listed as top secret, Soon the Ministry of Defense restarted the research program, and a large number of people were formed to study the source of the signal, and finally based on the time of the signal reception, some people boldly asserted that it was closely related to the Tunguska explosion in Russia, and naturally, this signal was understood as a greeting from a visitor from outside the world, and soon Puerto Rico began to build the Arecibo Observatory. Park Zhengyu gushed endlessly, as if he knew everything, although it sounded difficult to distinguish between the real and the fake, but outside he did get the mysterious alloy on the spaceship, which made Liu Weiping and Han Bingbin have to believe him.

"But why didn't Assange know about this origin, his father and himself were both directors of the radio department of the Arecibo Observatory." Liu Weiping was still puzzled.

Of course, he didn't know that the project was kept strictly secret, everyone only knew a certain part of the project, and even the senior officials at Roosevelt Roads Naval Base didn't know the whole thing. During the Great Matsushiro Earthquake, Arecibo had a brief moment of excitement, but soon discovered that it was not the outer space signal they were looking for. So when the elder Assange couldn't make progress, the U.S. Department of Defense decided to send Westinghouse's Clifford to help, but because of the accident, he became deaf, and the line was completely broken. Park Jung-woo talked for a long time before he got to the point, "When Germany surrendered, the low-level engineers of brainwave research were captured by the Soviet Union, and they also built huge antennas in the Far East, trying to carry out the same research, of course, there was no progress, and the weak brainwave signals could only be transmitted through conditions such as earthquakes and aurora or long-distance power transmission with Tesla." However, during the Vietnam War, the Soviets learned about the use of American brainwave weapons from the battlefield in Vietnam, and they learned the true origin of the Arecibo project through various channels, and obtained the information on the smoked glass. This convinced the Soviets that the wreckage of the Extraterrestrial Spacecraft was buried in the Tunguska region, and they began large-scale excavations, but nothing else came of it after the discovery of the mouth of the Selen River. ”
