July 13, 2045 at 14:50. "In the tens of billions of years of history of the universe, life on various planets is engaged in a long race with different starting lines. Some lives run to the front, and one by one they will knock out the lives behind them. We ......"

A female professor of thirty-five or sixteen years old was speaking in an impassioned tone from the podium. She was dressed in a formal suit and wore a pair of old-fashioned glasses. She likes to have one hand on her waist and the other pointing at the screen to lecture.

The audience was full of people, not only students, but also many young people who could see their careers at a glance, and even some old people who had turned white.

Xuanyuan Cheng didn't go to see Li Xing today, because she had to follow her tutor to teach all day today. In fact, she and Li Xing were in the same class when they were in elementary school, but then every few years, Li Xing was one level higher than herself, and now she is still studying, but Li Xing has been working for several years.

Her supervisor, Nangong Bai, is a professor of history at Majiazhen University, with a focus on modern interstellar history. Today's class is not an ordinary teaching class, but an open class for the whole city that has been prepared for a long time.

She attaches great importance to her class, and a few days ago there was an accident on the 10th of the stars, and she proposed to organize a public class to let more people understand interstellar history and realize the crisis from the universe.

Xuanyuan Orange tapped on the computer keyboard, and a picture was displayed on the huge screen in front of the people.

Below the photograph is a vast rice field with several people next to it, two of whom are facing each other as if they were exchanging something.

A third man was pointing to the sky with one hand and patting the shoulder of the person in front of him with the other, motioning for the two of them to look up at the sky.

The fourth and fifth men both lowered their hands stiffly, their mouths widened, and they looked up at the sky with surprised expressions.

Directly above the rice paddies, a huge luminous figure is floating in the sky. It's brighter than the sun that appears in the corner of the photo at the moment.

The shape of this luminous object is a very standard octahedron, and if it were to fall to the ground, it would crush the entire rice field.

"On October 9, 2025, the family was preparing to harvest their rice fields when they noticed a huge luminous object in the sky, and one of them took a picture with his mobile phone."

After this, a gap slowly opened in the lower part of the luminous body, and two alien beings in small vehicles came out of it. This alien life looks like a floating ball of transparent glass, and a small black solid ball in the glass ball is constantly moving, like their sensory system. They call themselves Disers. ”

"The Dyesians claim that they have extremely advanced technology, which can create starships like this luminous body, which are far faster than the speed of light, and translation devices that can sense the minds of other species and convert their own language into the language of other species."

"Their planet is rich in resources for them to live, but the nature of their species is to explore. This nature drove them to build super-powerful starships and sail them in all directions of the universe. ”

"Because they were attacked by the Terres during their voyage, they deviated from their original orbit and traveled to the solar system. I accidentally discovered that there is still life on this blue planet. ”

"They only came here to take some earth-specific material as a memento of their interstellar exploration. In fact, anything can be done, because they don't care about any resources, they only care about the process of exploration. ”

A few farmers stared at the strange-looking Disers, and the human language emitted through the translation device sounded quite strange. But everything in front of me is obviously real, not a dream. ”

"'What shall we bring back with us?' A Diser asked the farmers. The farmers were stunned and speechless. ”

"The two disers turned their black balls closer together, and then kept vibrating as if they were communicating something."

After communicating for a while, one of the disers turned the black ball in his body in a different direction, facing the huge luminous body, and vibrated a few more times. I saw that the light that had been scattered around the luminous body slowly gathered and threw itself into the rice field directly below. ”

Immediately, people felt a strong hurricane rise around them, and they all retreated. As if greatly attracted, the rice was pulled out of the dirt and flew towards the luminous body. The moment they approached the luminous body, they all vanished. ”

"'We don't care about matter itself,' one of the Disers emphasized, 'In exchange, I'll give this to you.'" As he spoke, he threw an object at the farmer below. ”

"The thing didn't do what it was supposed to be in free fall, but slowly floated into the hands of a farmer. When the farmer picked it up, it looked like a miniature version of the Diss, a palm-sized transparent sphere with a small black ball scurrying around inside. ”

"'Okay, it's time for us to get back on track with ourselves, we've discovered one more planet than the Centerline Exploration Group, and we can't wait to show them off.'" 'If you go back to normal orbit, you still have to watch out for the Terres, they ......' the Disers turned off the translation device, and the farmers could only see the small black balls vibrating inside them, and they could no longer know what they were saying. ”

The two disers exchanged for a short while, and then piloted the craft back to the giant luminous body. After they enter the luminary, the notch of the luminaire closes. The glow slowly diminishes until it is completely dimmed. Then, suddenly, a wide range of dazzling light emanated into the surroundings. ”

"A few farmers couldn't open their eyes at all, but only for a moment. The light that made the sun dim was gone immediately, and after a while, the farmers opened their eyes and found that there was nothing left in the sky. They were surrounded by ripe rice for a few minutes, and now all that was left was turned black soil. ”

"Everyone is a little confused, and they don't know what to do. One of the farmers was still holding the 'gift' given to him by the dishman. ”

"The farmers made their plight public, and showed up the photographs they took, the vanished rice fields, and the 'gifts' of the diss in exchange. But the voices in society are half believing and half denying. Many anti-counterfeiters pointed out that the photo was computer-generated, that the rice fields were destroyed by themselves, and that the 'gift' was the handiwork of a primary school student. ”

"The debate over whether or not aliens have ever been there has been going on for a month, until November 3, 2025 to be exact, when no one says that this is an alien arrival on Earth is fake."

"Because, the Terry is here......"
