According to the uncertainty principle of quantum physics, the existence of the quantum state itself is in a fuzzy state. Just like the wave-particle duality of light, state collapse will occur in reality only when there is an observer.

, return to a deterministic state.

The famous quantum physicist Schrödinger once proposed a hypothesis about cats, that is, assuming that there is a cat in a box containing a small amount of radium element and highly toxic cyanide, and there is a probability of the decay of radium element.

If the radium decays, it will trigger the mechanism to break the bottle containing cyanide and poison the cat to death. If the radium does not decay, the cat can continue to live.

According to the theory of quantum mechanics, since radioactive radium is in a superposition of two states: decay and non-decay, the cat should be in a superposition of dead and alive. In other words, the cat is both dead and alive.

When an observer opens the box and observes the cat's living state, the cat's quantum superposition state will immediately collapse into a state of death or survival.

When the observer does not exist, the cat is a "ghost" that is both dead and alive.

Liu Cixin, a famous Chinese writer, once put forward a conjecture in his novel, that is, by using quantum weapons to destroy armies with extremely strong willpower, you can get a group of ghost-like quantum armies.

When the observer does not exist, this unit can pass through any obstacle without being harmed by anything, and can even directly enter the heart of the enemy and deliver a fatal blow.

Shen Feng had previously studied the feasibility of quantum weapons with Jingwei, but because he really didn't have much time to engage in specialized research, he stopped at a superficial level.

Everything happening in front of them now is completely the existence of the hypothetical quantum ghost!

According to the description in the epic, Bloody Kraken had already been annihilated in a certain battle and disappeared completely. To be able to appear here and disturb the surrounding sea water, and then suddenly disappear after meeting Shen Feng and others, is obviously

It is in a quantum state.

Based on the information he had previously obtained, Shen Feng originally thought that before the world was flooded, it would be great for humankind's technological level to achieve controllable nuclear fusion, but he did not expect that even quantum weapons would be developed.

But even with quantum weapons, human civilization has still failed. How powerful are those world beasts? Where do they come from?

With doubts in mind, the sail battleship Hope broke through the layers of sea fog and arrived at the place where the bloody Kraken and the world beast appeared just now.

At this time, there was nothing else here except the violent waves that were gradually receding.

The sailing battleship Hope turned around a few times and found nothing. Not to mention the super giant war armor, not even a fish was seen.

Just when Shen Feng was feeling disappointed, a melodious whistle suddenly sounded in the distant sea fog, and even a roar came from the sky, which seemed to be the sound of a fighter jet passing through the sky.

Shen Feng immediately ordered to chase in the direction of the sound.

Soon, everyone faintly saw the outline and shadow of a battleship flashing through the thick fog in the distance, and there were also vague fighter planes flying through the fog in the sky.

But then these battleships and fighter planes became indistinct and disappeared completely, never to appear again.

Shen Feng frowned and understood that if his inference was correct, this battleship and this fighter plane also belonged to the quantum state.

It was difficult to find anything here. The sailing battleship started again and continued sailing in the fog area under Cherry's guidance.

After experiencing the scene of the bloody Kraken fighting the World Beast, Cherry, who had been deeply hypnotized, became even more excited at this time. He muttered something about "everything will be purified" and began to carefully search for a path to the Purification Church.

The signal device in his hand flashed more frequently at this time, and the red light on it seemed to be an eye, shining in the thick fog.

The further you go, the more "ghosts" and "ghosts" appear.

Broken aircraft carriers, fighter planes falling from the sky, World Beast tentacles floating on the sea, and so on, there are even phantoms of islands, and the voices of humans struggling and crying in the sea.

But without exception, when these things are observed, they quickly disappear without a trace, as if they had never existed.

Shen Feng's brows furrowed as he basically understood what this place was.

This sea area is an ancient battlefield where extremely brutal battles took place.

Moreover, it should be that a certain party used quantum weapons, which affected a wide range of sea areas, causing the current situation.

The reason why I say "a certain party" is because Shen Feng is now a little unsure about what is going on with this quantum weapon.

After all, the quantum state existences that appeared in front of us included human weapons and warriors, as well as the remains of some World Beasts.

Seeing that the captain was very calm and did not react much, the crew could only put their hearts in their stomachs for the time being and follow the captain forward.

After all, although those ghosts looked scary, they did not harm them.

Moreover, everyone believed that those ghosts were the spirits of ancient heroes and would naturally not harm them, who were also humans.

On the other hand, Wu Ta tried to find out what "quantum ghost" was from Shen Feng several times, but after listening to Shen Feng's explanation several times, he still couldn't get the point and could only give up temporarily.

Shen Feng also understood this.

Although quantum physics can barely be explained in basic terms in popular language, this is also based on the premise that the audience has a higher education foundation.

Although the knowledge Wuta possesses is considered top-notch in the apocalyptic world of water, its value may not be as high as that of a high school student.

Trying to understand quantum physics in this way is just like a castle in the air, and it is basically impossible.

On the other hand, Cherry's expression became more and more excited at this time. He tightly grasped the signal detector in his hand and leaned out half of his body to look at the thick fog ahead, excited.

The light on the signal detector flashes faster and faster, almost becoming continuously bright!

"Level 1 combat readiness, all weapon systems are turned on and ready to fire at any time." Shen Feng quietly ordered.

The various artillery, machine guns, etc. on the entire sailing battleship immediately entered combat mode. After several days of hasty training, a group of sailors were sitting on the gun emplacements in an uneasy mood. They did not understand why the captain issued this order. Order.

At this moment, the signal detector in Cherry's hand flashed suddenly, and then the red light turned bright for a long time and stopped flashing.

The next moment, the sail battleship crashed through the thick fog in front of it and appeared on the open sea.

Colorful colors came oncoming, and all kinds of gorgeous lights were instantly reflected on the entire ship. In front of everyone, a small island like a fairyland suddenly appeared. On it, the glow shimmered, and gorgeous buildings rose into the sky.
