"Ding-dong-" Another email prompt sounded, and this was the sixth email since yesterday evening.

Dr. Brian opened his eyes, a few strands of silver hair on his wrinkled forehead, and under the brown tortoiseshell frames, the deep blue eyes that had not slept all night were bloodshot. He sighed, straightened up from the wide armchair behind the Mahogany desk, and clicked on the mail, and sure enough, there were still several well-made crop circles and survey reports. Looking at it, the doctor no longer had the surprise and excitement he had when he first saw it, he took off his glasses, pressed the center of his locked eyebrows, and thought deeply. Yesterday evening at about six o'clock he read the first such email, which was from Hampshire, England. Without having to click on it, the Doctor knew it was a report email about the discovery of a new crop circle. His castle now has three satellites that are used to monitor the Earth's magnetic field and detect abnormal electromagnetic waves. Sanjay, who manages the satellite, is a typical crop circle fan, and whenever there is a report that the crop circle is a natural phenomenon or a human prank, Sanjay will open his big, round eyes, and a simple, dark, childish face will swell red, and he will shake his head in protest in the way that no one can understand.

"You know: the largest span of the wheat circle is more than 180 meters, larger than a football field, the complex wheat field circle has a total of more than 400 circles, there are no traces of people, animals or machinery nearby, no one has witnessed the circle pattern production process, even the animals are far away from the scene. Who can produce such a monumental work in the middle of the night without being discovered, Doctor, do you say that with your abilities you can? ”

Brian will most likely say at this time: he can't, but maybe someone can, because nothing in this world is impossible, after all, their own existence is impossible for ordinary people.

The 21-year-old Indian boy then tells the history and phenomenon of crop circles in his characteristic Indian English: they are more than 350 years old and first appeared in England in 1647. Since then, this mysterious phenomenon has continued to appear, and crop circles have been frequently found in the United States, Australia, Europe, South America, Asia and other places, most of which are still in the United Kingdom. Circles mostly form at night, usually between midnight and 4 a.m., and form at an alarming rate. Figures are drawn with absolute precision calculations, often with very complex geometry or gold separations. The crops in the crop circle are dumped in a certain direction, in regular spirals or straight lines, sometimes woven in layers, up to five layers, but each crop is still in an orderly order. The soil in the crop circle contains many small magnetic grains, which can only be seen under a microscope, and contains trace amounts of radiation of non-natural radioactive isotopes, which are three times higher than normal. The infrared light inside and outside the pattern is enhanced, and the structure of the carbon molecule at the bending position of the wheat straw is abnormal due to the electromagnetic field, but it can continue to grow normally. Grows faster than wheat that is not overwhelmed. Most of this phenomenon occurs in the energy belt of the Earth's magnetic field, when the surrounding electromagnetic field weakens, and the compass, telephone, battery, camera, car and even power station are abnormal.

"This is definitely not something that humans can do, at least not earthlings!" Sanjay shook his head like a rattle.

In the UK, Hampshire and West, where crop circles are frequent, Sanjay used his power to set up satellite monitoring points and observation stations. Crop circles, orthodox physics research institutes are dismissive. As a former quantum physicist at Yale University, Ph.D. also learned that science is based on credible experimental evidence—any theory that cannot be proven to exist can be dismissed as nonsense. Brian was deeply influenced by the worldview of traditional science, although neither he nor the entire existence of Klesterburg could be explained by existing scientific theories. Of course, the Doctor is not a rigid and stubborn person, and although he does not believe that this is the work of aliens, he does not deny the mystery of this phenomenon. At the same time, anomalies in the low-band electromagnetic waves of the Earth's magnetic field rarely occur, and satellites are idle, so the doctor acquiesced to Sanjay's research.

When he clicked on the first email, the doctor was still a little surprised: the crop circle spanned more than 400 meters, more than three times the size of the famous giant crop circle in Oxfordshire and Kingston Canyon, and the circle pattern was so beautiful that it was as beautiful as any masterpiece of art. Before the doctor could finish reading the report, the second email beep sounded again. The doctor clicked on the second email, and a picture of the same crop circle appeared in front of him. Brian smiled and shook his head: the staff at the monitoring station were so confused, the same report was sent twice. Soon, a third email arrived, and the doctor clicked on it: except for the angle and height, all of them were identical crop circle photos.

"What's going on, is it their prank?" Brian glanced at the bottom right corner of the computer screen: March 2nd, April Fool's Day, April 1st.

Then there was a fifth, a sixth, almost identical content, and Brian took a closer look at where the email had been sent. He was shocked by this: the emails came from Wiltshire in the UK, Texas in the US, Yogyakarta in Indonesia, and Togliatti in Russia!

He picked up the phone, and a few minutes later, a sleepy-eyed Sanjay pushed open the old and beautiful French double doors of the study and walked in, opening his mouth to speak with a strong smell of curry, apparently the big Indian boy who was busy with games had forgotten to brush his teeth before going to bed. As the Doctor had expected, Sanjay's expression was exaggerated when he saw the mail, as if he had seen a prehistoric beast, and he howled indiscriminately, while Brian sat gracefully and patiently on the couch waiting for him to calm down. Sanjay frantically called to confirm the information, but the strange thing was that the calls were all busy signals, the EMAIL of the monitoring station, and the Facebook of the staff could not be contacted.

"Dare to cut off my net?" Sanjay howled, as if a hungry kitten had smelled fish.

He jumped up and rolled up his sleeves and sat unceremoniously in Brian's armchair, having to pad his ass on one leg to reach the computer because he wasn't tall enough. He was busy on the computer with his teeth and claws, his short dark and shiny hair, and with the slight vibration of the air around him, like a hedgehog's mane, pointing straight at the computer. At the same time, a crackling beep mixed with static electricity echoed in Brian's study, accompanied by a mysterious incantation from Sanjay. Brian paced steadily, his cheeks flat, his gaze calm, his thin lips pursed tightly, and his expression like that of an ascetic. More than a decade later, this feeling is coming again. He walked over to the window and pushed open the tall, heavy floor-to-ceiling windows. Outside the window, the night was deep, and a mountain breeze with a cool and sweet smell was blowing in his face, Brian took a deep breath and slowly spit it out. The cold wind curled the curtains, the wood in the fireplace crackled, and the flames were disturbed by the cold wind, leaving a ghostly light and shadow on the surrounding walls.

He doesn't know what this means today, but if it were to be reported in the media tomorrow, he can imagine what kind of uproar it would cause. And that's not what worries him most: What does it mean to lose contact? What forces are threatening his monitoring station? The network and communication of the castle and the detection station are all based on their own satellites as relay stations, and the encryption technology of the microwave frequency band is original to Sanjay, and the beam can jump instantaneously, and it is almost impossible to intercept or interfere with their system. Unless they are from within, the staff at the monitoring station are from his castle, the people he trusts, and the people he has always protected and cared for.

Is it really as Sanjay said: all this is the work of intelligent life beyond the earth? Brian couldn't be sure, but vaguely, he sensed that a great change affecting everyone on Earth was coming!

"Bo, Doctor! Come here! Sanjay stammered, and Brian hurried to the computer.

On the screen, a satellite receiving tower towers under the starry night sky, and the red light flashes at the spire, and everything seems to be very normal. Suddenly, after a scream that pierced the air, only white noise remained on the screen.

"This is outdoor surveillance video from a surveillance site in Texas, USA, and I've checked other videos and communications, and they were all cut off at the same time, and everything was fine until then, only this," Sanjay said, sliding his arm like a Chinese qigong master.

The buzzing sound mixed with static electricity intensified, and a magical scene appeared: the light in the study dimmed, and the outdoor surveillance video of the Texas monitoring point in the United States was displayed in 3D in front of them. "Beau, Doctor, look!" Sanjay flicked his hands, and the scene grew larger, and next to the satellite receiving tower was a T-shaped steel building. The buildings stand in the middle of nowhere, but the glass curtain walls are brightly lit, and the Sanjay turns his gaze to the sky, the Milky Way hangs like a bridge in the night sky, and the cries of animals such as foxes, owls and jackals echo everywhere, and they can even feel the cold and humidity of the North American night. Everything was so quiet and beautiful, a sudden black ball smashed, and everything disappeared. All that was left in the study was the roar of the computer and the grinding of Sanjay's gums.

"Are they all dead?" Sanjay's voice was low and trembling.

"Judging from the landing point of the black ball, it is aimed at the satellite receiving tower. The station's alloy frame is a space structure that can withstand the Nine Poles Earthquake, and its glass is high-strength bulletproof glass, so as long as it is not directly hit, it should be safe. Brian replied thoughtfully.

"W-then, what's that black ball, is it an alien spaceship?" Sanjay stammered even more, a face contorted with the undissipated traits of adolescence, unable to tell whether it was excitement or fear.

Except for the crackling of the charcoal fire in the fireplace, there was silence in the study for a long time before Brian looked back at Sanjay's bewildered eyes.

"I'm afraid I'll disappoint you, kid. This is probably the masterpiece of our earthlings themselves. Brian's voice was surprisingly calm, and it was clear that he had the answer in mind.

"No, it's impossible, it's absolutely impossible to intercept and block my signal! I can perceive electromagnetic waves, touch electromagnetic waves, I am the 'electromagnetic king'! But... Could it be that there really is someone beyond my power? Sanjay muttered quickly.

"No, it doesn't take any high-tech or superpowers." Brian comforted Sanjay, looking mocking and helpless, he sighed secretly: Isn't it always the way we earthlings deal with problems when they encounter problems that cannot be solved, resorting to force?

"Kid, no matter how perfect your design is, it's no match for a bomb!"

"Wouldn't it? I didn't see any sparks, and I didn't have a ballistic trajectory in the sky. ”

"There is a kind of cannonball that fires silently and without fire..."

"Electromagnetic bomb?!" Sanjay interrupted Brian's explanation: "But this is the territory of the United States, who would dare?" Who can? In broad daylight? ”

Brian didn't go any further, looking somewhat similar to that of a disappointed Sanjay, but for different reasons. He stretched out a slender and withered hand, and a spherical walkie-talkie on the other side of the desk, elegantly drew an arc in the air, and obediently fell into his hand.

"Avery!"

"Yes, Doctor, I'm here." A revered and loyal bass voice came from the other end of the intercom.

"Call a few children at home, don't alarm Madame, come to the study and wait for me, I'm afraid we'll have to go out for a ride."
