The contact with Hao Yun made Shen Yunhong deeply reflective.

After two world wars, the earth is currently in a precious period of peace, although peace is relative. Far away in the Middle East, Africa and some parts of Latin America, the flames of war are still burning, but they are far from threatening the survival of humanity as a whole.

However, the terrible aliens are coming, and if they don't find effective means of confrontation in these short decades, the earthlings can only sit and wait for death, and they can't even find the rear where they can take refuge, is the situation really so bad?

That night on the wasteland, the content of sitting under the starry sky and thinking broke into Shen Yunhong's mind again, this time not only lingering, but also seemed to be mixed with a body of blood, and it has been flowing into his heart.

Without feasible technology, his idea is indeed a fairy tale, but if he really obtains that kind of technology, the fairy tale can become a reality. And the technology actually exists, in the hands of the enemy, he is like a hungry man who has found a harvest field, and wants to go over to pluck the golden and full ears of wheat, but he cannot cross a wide river separated in the middle.

However, one day, Powell smirked at him as if he had gone insane and said: We succeeded!

"Success? What kind of success do you mean? Shen Yunhong asked as if he was staring at a boat crossing a river.

Powell didn't answer, jumped up from the ground with a glass flask, hit his head on the corner of the table, and the pain was so painful that he couldn't care about his cracked teeth, and dragged Shen Yunhong to a bulky but mobile computer and said: This portable computer is highly encrypted, and no matter how powerful a hacker is, don't want to break into the database on the hard disk. It uses the most advanced MS-DOS 1.0 V system available, and I now grant you permission to operate on it as you please. ”

"What about you? What are you going to do? This trouble made Shen Yunhong even more confused.

Powell looked almost frantic with extreme excitement, pointed to a corner of the laboratory and said, "There's a minimal version of a desktop computer over there, which is basically obsolete and useless, and I'll just sit there and read what you're doing here." You keep in mind that the power supply between these two computers is independent, there is no data cable connection, and at the moment, there is no medium that can communicate with each other, which you can understand without my introduction! (Author's note: Bluetooth or digital communication technology did not exist in the 80s.) They are connected by a vacuum hose with a diameter of one centimeter that can be disconnected from the middle. The hose is an absolute vacuum, put a mosquito in for a few seconds and it will kick its legs. Then I put the trillions of special electrons in this bottle into the vacuum tube! ”

Shen Yunhong's mind calmed down, and gradually, he began to understand the meaning behind Powell's crazy move. Suddenly he was excited, as if he was walking in a lifeless ice and snow, and suddenly saw a flower blooming, and the surprise made him tremble, and he had never looked forward to such a moment in his life.

On the black screen of the laptop, the cursor blinks like a curious little eye. Those DOS languages composed of numbers, like white tadpoles born from the darkness, fell into Shen Yunhong's eyes full of life. Maybe they are really the hope of mankind, and can lead the earthlings to defeat the aliens?

After successfully entering the system, Shen Yunhong trembled his hands and wrote a sentence with an unfamiliar Wubi input method: Xiaoyun, Xiaoyin, are you okay?

Powell walked over to the dusty, gray-covered desktop with even the monitor, and let out a long breath. At this time, not only did he lose his signature smile, but his pious expression was closer to the *** of the pilgrimage in Mecca.

Shen Yunhong only wrote one sentence, and after writing it, he raised his head and watched Powell's every move intently. Only then did he realize that what the man was holding in his arms was not an ordinary flask, but a glass tube that was thin at the top and thick at the bottom, and the thinnest part was as thick as a wrist. Each end of the glass tube is sealed with a "wood" piston. The metal cap is not used, presumably to prevent the particles in the tube from reacting with the metal.

Powell picked up the vacuum hose for connection, disconnected it from the front, and plugged the two broken ends towards the ends of the glass tube. He did it so carefully and meticulously that it was like an explosives disposal expert defusing a bomb.

However, the operation process he designed is also very safe, the plug that seals the vacuum hose looks like wood, but in fact it is made of what material, and after pushing the glass tube, it melts like ice. In this way, the glass tube and the hose become one, forming a closed vacuum electronic circuit.

The other two ends of the hose were filled with crystal heads, one end plugged into the port of the desktop host and the other end plugged into the port of the laptop, and in this way, Powell built a vacuum electronic channel between the two computers.

Nervous to nervous, Shen Yunhong felt that the game in front of him was as funny as playing guess with his two daughters at home, the only difference was that if the daughters guessed wrong, they could start again, and Powell guessed wrong, and he could only return disappointed tonight.

Powell clasped his arms to his chest and stared at the monitor without saying a word. His demeanor was highly focused, and the dust on his computer was very disturbing, but it didn't seem to obstruct his vision at all.

I don't know how long I need to wait, and I don't dare to easily disturb the other party's train of thought, Shen Yunhong's heart is up and down, and his mind is rarely blank. The cave laboratory was so quiet that you could hear the sound of dripping water in the cracks in the rocks outside, and the sound of the water was eerie, like a ghost crying.

Time passed minute by minute, and the two of them were patient, and they suffered for more than two hours.

Suddenly, the light in Powell's tired eyes flowed, the corners of his mouth rose slightly, and he read it out in standard Chinese with a trembling Adam's apple: "Xiaoyun, Xiaoyin, are you okay?" Then he added in a very unfamiliar tone: "'Door' is a typo, missing a single side." ”

Shen Yunhong sat on the stone bench, and his whole person seemed to be petrified. Everything in the laboratory began to fly before his eyes, forming a huge vortex to swallow him, and he seemed to stand at the beginning of the world, all about the emergence of the earth, the separation of the sea and the land, the birth of single-celled organisms, the domination of dinosaurs on the continent, the evolution of apes into humans, etc., etc., these fragments of the development of the earth popped up one by one like movie films, and disappeared after falling into the chaotic cyclone. But there is no Pangu to open the world, Nuwa's feat of creating man, all materialistic and idealistic ideas have been erased from the history of the earth, starting from scratch, is happening in the vacuum electronic circuit created by Powell, to Shen Yunhong after tonight, mankind is destined to embark on a completely different path of development from the past.
