A huge fireball engulfed both the droplets and the bow of the Ark, and the blinding light made even the dome of the dungeon snow-white, making it impossible to see anything.

Countless people are anxious to know what the situation is, but they don't get any news.

Fortunately, they didn't observe all of this directly from the ground, otherwise it would be no different from seeing the consequences of a nuclear explosion with the naked eye.

The firelight suddenly illuminated half the world, making the side that had been night as bright as day at this moment.

Luo Ji, who was on the Ark, was probably the most confused, and at the moment when the water droplets rushed in front of him, he had even replayed his life in his memory, which was commonly known as the marquee.

His life is divided into two distinct parts, one after becoming the wall-facer, and although it spans two centuries, it feels compact and dense like a day yesterday.

He quickly turned this part backwards, because this part did not seem like his own life, including the unforgettable love, it was like a fleeting dream, and he did not dare to think of his lover and children anymore.

Contrary to his expectations, the life before becoming a wall-facing person was also a blank in his memory, and all that could be fished out of the sea of memories were fragments, and the further he went, the rarer the fragments became.

Did you really go to elementary school? Did you really have your first love? Occasionally, a few clear scratches could be found in his fragmented memory, and he knew that something had happened, and the details were vivid, but the feeling was gone.

In the past, it was like a handful of dry sand in your hand, thinking that you were clutching it tightly, but in fact, it had already flowed through your fingers. Memories are a river that has long since dried up, with only scattered gravel left in a lifeless riverbed.

His life is like a bear breaking corn, getting it and discarding it at the same time, and in the end there is not much left.

The raging fire outside the porthole illuminated his face, even though the Ark had super heat insulation and radiation protection functions, it still made Luo Ji feel as if his whole person was about to evaporate.

In the end, he fell heavily to the ground, and at the same time recovered from the marquee, and Luo Ji was surprised to find that nothing had happened.

The flames outside the porthole gradually faded, and the pitch-black cosmic background reappeared in front of him, but there was no trace of the water droplets, and he was not instantly vaporized by the ultra-high temperature propulsion aura of the water droplets as he imagined.

"What's going on? What about water droplets? Luo Ji blurted out.

"It's over."

Qiao Lu's voice came from the side, making Luo Ji understand that this was not a dream.

But he still couldn't understand how it was possible for a kinetic cannonball to penetrate the strong interaction shell of a water droplet.

As if seeing through his doubts, Qiao Lu smiled slightly:

"It's antimatter, and the explosion you see is caused by antimatter."

"You blew up the droplets with antimatter?"

Luo Ji originally wanted to say that this was impossible, indeed antimatter weapons were extremely powerful, and antimatter the size of a rifle bullet was enough to destroy a stellar warship.

However, the strong interaction of the water droplets is also indestructible, and no amount of explosion is enough to destroy it.

But then he reacted and corrected: "You annihilated the droplets with antimatter? ”

"Correct." Qiao Lu smiled and nodded.

It is generally believed that the terrible thing about antimatter weapons lies in their terrifying energy release, one gram of antimatter is equivalent to the energy of a 200,000-ton yield nuclear bomb, that is, the power generated by the explosion of 300 grams of antimatter can exceed 50 million tons of equivalent Tsar Bomba.

But if you only rely on the power of the explosion, the water droplets can resist human civilization at least 350 million tons of stellar hydrogen bombs unharmed, and the explosion caused by replacing them with antimatter will make no difference.

Therefore, what Qiao Lu really uses is the annihilation of antimatter and positive matter in contact, so as to penetrate the indestructible strong interaction force shell of water droplets.

No matter how powerful the water droplet is, it is just a conventional positive matter composed of atoms and molecules, as long as it is a positive matter, it will be annihilated by antimatter, so it doesn't matter how hard the strong interaction force material is, it is just the most basic physical law.

This is the limitation of water droplets, and even hard matter cannot avoid being annihilated by antimatter.

As a result, the droplets were completely wiped out, and the Ark withstood the explosion unscathed.

Luo Ji further asked: "That's not right, according to the data measured by the Praying Mantis, the water droplets weigh at least a dozen tons, where can you get so much antimatter to annihilate it?" ”

One gram of antimatter is annihilated by one gram of positive matter, so if you want to completely annihilate the water droplets, you have to take out the same weight of antimatter.

Nowadays, human civilization cannot even make a kilogram of antimatter, and tons of antimatter can annihilate water droplets.

What's more, if it is such a large amount of antimatter, even if the power of the explosion will not be only this extent, it will definitely affect the entire earth, and it is impossible for the Ark to withstand it.

Qiao Lu shook his head and said, "Not so much, we only use one gram of antimatter." ”

"One gram!?"

Luo Ji was greatly surprised, if it was just a gram of antimatter, then human civilization really couldn't get it.

Antimatter is not something that only exists in theory, as early as 1995, CERN scientists created the world's first antimatter - antihydrogen atoms in the laboratory, and in 1996, the Fermi National Accelerator Laboratory in the United States successfully created 7 antihydrogen atoms.

In the 23rd century, human civilization has been able to produce a few grams of antimatter, but considering that its power is far less than that of the stellar hydrogen bomb, it has not been used as a combat weapon.

Qiao Lu successfully destroyed the water droplet with one gram of antimatter, doesn't that mean that the answer is always in front of him?

"How the hell did you do that?"

"It's very simple, because the strong interaction of the water droplets is only one layer of atom thick."

The reason why we can realize this is because the Wandering Earth has also developed materials with strong interaction forces, and as long as you compare them with water droplets, you can know why.

The shells of the Earth Cannon are not much larger than water droplets in size, but they have the weight of a whole planetary engine, and the molecules of the materials with strong interacting forces are so tight that even the nuclei of the atoms are squeezed together, and the density is of course many times higher than that of natural matter.

However, the mass of the water droplet is normal, at least not to the extent of outrageous, which means that the strong interaction force material only exists in its outer layer, and there are other mechanical parts inside the water droplet.

Finally, according to Ding Yi's calculations, if the entire surface of the water droplet is to be wrapped with a strong interaction force material, and the mass is kept within the normal range, the thickness of one layer of atoms can only be maintained.

Anyway, in the face of conventional weapon attacks, there is no difference between a layer of atom-thick strong interaction force materials and a one-meter-thick strong interaction force material, and they are both the same and cannot be penetrated.

If the content of the material with strong interaction force is further increased, the weight of the water droplet will inevitably be doubled, and the steering ability will be affected by excessive inertia.

The thickness of a layer of atoms is the most mobile and defensive design, and the three-body civilization has also achieved the ultimate in this regard.

But this leaves an Achilles heel for the water droplet, as long as the weapon can break through the strong interaction force material, even just one gram of antimatter, it is enough to disintegrate the water droplet's shell.

When the shell is broken down, the energy released by the annihilation of antimatter pours into the interior, destroying the internal generator of the water droplet, the positively charged nucleus quickly discretes, and the atom returns to normal motion, becoming a metal-like alloy with the same weight as the original water droplet, then it is no different from ordinary matter.

This is the truth about the destruction of the water droplets, and the Ark fired antimatter armor-piercing shells not so much antimatter!

By loading a gram of antimatter inside the shell, at the moment of hitting the water droplet, the antimatter successfully touches the water droplet, and annihilation occurs to disintegrate the indestructible strong interaction force shell, and the rest is left to the energy equivalent to the explosion of a 200,000-ton yield nuclear bomb!
