Road to science and technology

Natural Selection's massless fusion thruster emitted blue tail flames and flew past the Mantis, which was about to catch water droplets.

"It's going to be a long time before we say goodbye!"

Ding Yi, who had gray hair, was wearing a space suit, standing still and watching the tail flames streaking through the starry sky fade away, slowly turning into a point of light, and a sentence that only he could hear rang from his heart.

He is a physicist, he was two centuries ago, and he still teaches cutting-edge physics in universities. Now that he is the first person to touch the water droplet, he is indeed expected by everyone.

Ding Yi actually knew it very well, but he didn't say it.

There are no songs or praises, only the accelerating light spots shouting, look...this is the hope of mankind.

Natural Selection will accelerate to 15% of the speed of light soon, and by then, the crew of Natural Selection will wake up from the deep-sea accelerating fluid.

The sleep in the deep-sea accelerating fluid was so wonderful that Chu Yan, who was as steady as an old dog, also led all members of the Blue Space to immerse themselves in it.

Ding Yi did not continue to sigh, because the entire space fleet was ready. A total of 2,015 warships were lined up in a neat queue. The sunlight five astronomical units away reflected the light of technology on their surfaces. This was the entire space fleet. Humanity has devoted its utmost resources to create space power over two centuries. Their powerful ships and cannons are quietly waiting for the arrival of water droplets.

The neat fleet array all illustrates the achievements of mankind in the past two centuries. In this way, mankind solemnly tells the Trisolarans: the era of intimidation has passed, and from now on, the offensive and defensive momentum has changed!

This sentence was originally said by Liu Che, Emperor Wu of the Han Dynasty, but the only thing missing is "If the enemy can go, I can go too!"

The fusion engines of the entire combined fleet sprayed fireworks to adjust their attitude. Soon after, a thousand kilometers away from the target, the combined fleet was synchronized with the speed of the water droplets.

Then most of the battleships shut down their fusion engines and floated quietly above the abyss of space. The 1.2 million people in the fleet held their breath and watched the short voyage of the "Mantis".

"Like a drop of Virgin Mary's tears." A voice of praise rang out on the channel!

The Mantis has adjusted its speed to synchronize with the water droplet, and then the mechanical arm slowly stretched out, and then firmly clamped the water droplet.

"Be careful, don't get scratched!" A voice sounded in the communication channel, telling the robotic arm operator.

But the scratching finally didn't happen, and the robotic arm began to retract.

Although the water droplet has an absolutely smooth surface, its surface is still curved. The Mantis's mechanical claws just happened to grab the two sides of the convex part in the middle, so this grasp caught the absolutely smooth water droplet. .

The water drop was as motionless as a cicada, and then the mantis, the Mantis, pulled it back to the main cabin.

The self-destruction of water droplets analyzed by military experts did not happen. So the current situation has confirmed people's speculation: if it is really a military detector, it will definitely self-destruct after falling into the enemy's hands. Now it can be determined that it is a gift from Trisolaran to mankind. It is difficult for this civilization to A peaceful signal sent by expressions that make human beings understandable.

The world is rejoicing, and people are rejoicing with enthusiasm and forgetfulness, because judging from the current performance of the Trisolaran detector, mankind has succeeded.

The appearance of the United Fleet in space gave the public an image of the power of mankind. Now, Earth's civilization has gained the confidence to face all kinds of enemies calmly.

"First do a material composition analysis!"

"Switch to electron microscopy mode..."

After using the electron tunneling microscopy mode to magnify 10 million times and unable to see the uneven surface of the water droplets, Ding Yi thought that the magnification equipment was wrong. However, after I tried to magnify the cuffs of my clothes, he confirmed that the amplifier was not working properly. Something went wrong.

Because this was a historic moment, every move Ding Yi made was broadcast live.

That's when he realized something was wrong.

"Geological hammer!"

"Give!"

Ding Yi took the geological hammer, raised his arm and hit it hard. The impact of the hammer almost made him lose his hand.

Then he took the amplifier that had been adjusted to the maximum power and pressed it on the place where he hit it.

The amplifier under the electron tunneling microscope is still the same, smooth and without any undulations or pits.

The researcher who was witnessing history next to him also saw Ding Yi's actions. At this time, he noticed that Ding Yi's face was solemn, so he asked: "What is the material of water droplets?"

"I can only guess." Ding Yi raised his head and said, "The molecules of this thing are closely arranged together and then firmly fixed, and there is no molecular vibration at all!"

"What force can do this?" asked the expedition team members who were accompanying him.

"Strong interaction!" Ding Yi said, with cold sweat on his forehead.

"Then...what does it do?"

"What does destroying you have to do with you?" Ding Yi said.

This sentence brought a moment of deathly silence. Just as the other three members of the expedition team and the millions of people in the combined fleet were chewing on its meaning, Ding Yi suddenly said: "Run quickly." These two words were whispered. , but then, he raised his hands and shouted at the top of his lungs: "Silly children, run quickly!"

Before Ding Yi shouted, the water drop remained motionless and quietly let him inspect it, allowing him to recognize its material and its technological content. From this point of view, the Trisolarans have learned the strategy and they want the water droplets to destroy human beings' belief in resistance.

Presumably at this moment, the Trisolarans watching all this through Sophon real-time communication must have laughed out loud. If they had that much emotion.

The moment Ding Yi shouted, the water droplet moved, and a blue halo appeared at the tip of the tail of the water droplet. The halo was small at first, but very bright, covering everything around it in blue light, and it expanded rapidly. , the color changes from blue to yellow and finally to red, as if the halo is not produced by water droplets, but just emerged from the ring.

As the halo expanded, its luminosity also weakened. When it expanded to about twice the maximum diameter of the water droplet, it disappeared. As it disappeared, a second small blue halo appeared at the tip, expanding just like the first one. , discoloration, reduced luminosity, and quickly disappeared. The halo continues to appear and expand from the tail of the water droplet, with a frequency of two or three times per second. Driven by the halo, the water droplet begins to move and accelerates sharply.

Ding Yi's voice could not be heard in the end because the strong interference caused by the water droplets disrupted the signal. The Mantis also melted in the halo of water droplets.

When the water droplet flew three hundred kilometers, it had exceeded 16.7 kilometers per second, and the acceleration continued.

When it passes through space battleships, the positions it passes through are all fuel chambers as if calculated, so when the nuclear fuel is passed through, the ultra-high temperature that propels the halo triggers a nuclear fusion reaction, and the fireball of the thermonuclear explosion is being After the impact point appeared, it expanded rapidly, and the entire fleet was illuminated by strong light.

The water drop attack continued, penetrating one Space Force warship after another with an interval of less than a second. There are explosions of light and shadow everywhere, and ship hulls that have been completely melted by ultra-high temperatures are everywhere. The melted metal turns into red liquid, and under the action of the explosion, it flies away in space without any resistance. Countless Tang Sect ships are everywhere. The disciple is using Rainstorm Pear Blossom Needle and Peacock Feather!

More than a minute later, all one hundred warships in the second queue were destroyed. Then the water droplet made another sharp turn. Three minutes later, the third queue also turned into fireworks. No, it was more like the rainstorm pear blossom needles of Tang Sect. .

Then came the battleships of the fourth and fifth queues that were no longer in formation...

At this time, water droplets continued to attack the warships that began to evacuate, and the speed of destruction slowed down. However, warships were destroyed in nuclear explosions every moment. If a certain person saw this scene, he might exclaim, "Explosion is art." !

"Water droplets! The attacking object is water droplets!" As time went by, people finally knew that it was water droplets that attacked them.

"Strawberry M's water droplets! Yeah...die!" shouted a Zaun gunner on the remaining battleship.

"Death to the garbage Trisolarans!"

The gamma-ray laser fired by the Zaun gunner's ship-borne laser weapon only refracted perfectly on the surface of the water droplet, leaving the water droplet unscathed.

The gunner who called the Trisolarans rubbish fired a precise kinetic energy weapon. The electromagnetic kinetic energy weapon, that is, the metal bullet fired by the electromagnetic gun, has huge destructive power. However, the huge kinetic energy brought by its high speed can only slightly slow down the speed of the water droplets.
