Chapter 389 364: Ancient Battlefield, Paradise Island
According to the uncertainty principle of quantum physics, a quantum state exists in an indeterminate state. Similar to the wave-particle duality of light, it only collapses into a definite state in reality when an observer is present.
The famous quantum physicist Schrodinger once proposed a thought experiment involving a cat. A cat is placed in a box containing a small amount of radium and deadly cyanide. The decay of the radium element is governed by probability.
If the radium decays, it triggers a mechanism that shatters the vial of cyanide, killing the cat. If the radium does not decay, the cat lives on.
According to the theory of quantum mechanics, since the radioactive radium exists in a superposition of both decayed and non-decayed states, the cat should logically also exist in a superposition of being dead and alive. In other words, the cat is simultaneously dead and alive.
When an observer opens the box to check on the cat, its quantum superposition immediately collapses into a single definite state: either dead or alive.
As long as there is no observer, the cat is a "Ghost" that is both dead and alive.
The renowned author from Hua Country, Liu Cixin, once proposed a conjecture in one of his novels: if you use a quantum weapon to annihilate an army possessing immense willpower, you could create a quantum army of ghost-like soldiers.
When unobserved, this force can pass through any obstacle, cannot be harmed by anything, and can even penetrate directly into the heart of the enemy to deliver a fatal blow.
Shen Feng had previously explored the feasibility of quantum weapons with Jingwei. However, they lacked the time for dedicated research, so they had only scratched the surface.
Everything unfolding before their eyes now was a perfect example of the hypothetical Quantum Ghost!
According to the epics, the Bloody Kraken had been annihilated in a battle long ago and had vanished completely. The fact that it could appear here, disturb the surrounding seawater, and then suddenly disappear after encountering Shen Feng's group clearly indicated it was in a quantum state.
Based on the information he had gathered, Shen Feng had thought it was remarkable enough that humanity had achieved controlled nuclear fusion before the world was submerged. He never expected they had also developed something like quantum weapons.
Yet, even with quantum weapons, human civilization had still fallen. 'Just how powerful are those World Beasts? Where on earth did they come from?'
With these questions lingering in his mind, the Hope-class Wind Sail Battleship broke through the dense sea fog, arriving at the spot where the Bloody Kraken and the World Beast had appeared.
Now, there was nothing here but the gradually subsiding, turbulent waves.
The Hope-class Wind Sail Battleship circled the area a few times but found nothing. They didn't see a Super Giant War Armor, or even a single fish.
Just as Shen Feng was feeling disappointed, a long, drawn-out whistle suddenly echoed from the distant sea fog. A roar even sounded from the sky, like a fighter jet tearing through the air.
Shen Feng immediately gave the order to head in the direction of the sounds.
Soon, the crew faintly saw the silhouette of a warship flash in the distant fog. In the sky above, they could also vaguely make out a fighter jet streaking through the mist.
Moments later, however, the warship and fighter jet grew faint and then vanished completely, not to be seen again.
Shen Feng's brow furrowed. 'If my deduction is correct,' he thought, 'that warship and fighter jet must also exist in a quantum state.'
With little to be found here, the Sail Warship started up again, continuing its voyage through the fog under Cherry's guidance.
After witnessing the Bloody Kraken battle the World Beast, the deeply hypnotized Cherry grew even more agitated. He began muttering, "Everything will be purified," as he carefully searched for the route to the Purification Church.
In his hand, the Signal Device blinked more frequently, its red light like a glowing eye in the dense fog.
The farther they advanced, the more "Ghosts" and phantoms appeared.
Wrecked aircraft carriers, fighter jets falling from the sky, World Beast tentacles floating on the surface, phantom islands, and even the sounds of people struggling and crying in the sea.
But without exception, the moment they were observed, they would vanish without a trace, as if they had never existed at all.
Shen Feng's brow was knit in concentration; he was beginning to understand what this place was.
This stretch of ocean was an ancient battlefield, the site of an incredibly fierce battle.
Furthermore, one side must have used a quantum weapon, affecting a vast area of the sea and creating the current phenomenon.
He specified "one side" because he was no longer certain about the circumstances of the quantum weapon's use.
After all, the quantum apparitions included human weapons and soldiers, but also the remains of World Beasts.
Seeing that their captain was perfectly calm and showing little reaction, the crew could only swallow their fears and follow him forward.
After all, while the Ghosts looked frightening, they hadn't caused any harm.
Besides, the crew all believed these Ghosts were the spirits of ancient heroes and would naturally not harm fellow humans.
Witch Tower, on the other hand, repeatedly tried to get Shen Feng to explain what a "Quantum Ghost" was. But even after several explanations, they still couldn't grasp the concept and had to give up for the time being.
Shen Feng understood why.
While it was possible to give a basic explanation of quantum physics in layman's terms, that still required the listener to have a foundation in higher education.
The knowledge Witch Tower possessed might be considered top-tier in the Water World Apocalypse, but in terms of depth, it was probably less than that of a high school student from before the cataclysm.
Trying to understand quantum physics with that background was like building a castle in the air—fundamentally impossible.
Cherry, however, grew increasingly frenzied. He clutched the Signal Device tightly, leaning halfway over the side to stare into the thick fog ahead, beside himself with excitement.
The light on the Signal Device was flashing faster and faster, nearly becoming a solid, continuous glow!
"Battle stations. All weapon systems online. Be ready to open fire on my command," Shen Feng ordered quietly.
All the cannons and machine guns aboard the Sail Warship immediately went into combat readiness. The sailors, who had only received a few days of hasty training, sat anxiously at their gunnery stations, not understanding why their captain had given the order.
Just then, the Signal Device in Cherry's hand flashed brightly, and the red light became a solid, unwavering glow.
The next instant, the Sail Warship burst through the last veil of fog and emerged onto an open expanse of sea.
A dazzling kaleidoscope of colors rushed to meet them. Brilliant light instantly washed over the entire ship. Before them, an island that looked like a fairyland had appeared. It shimmered with iridescent light, magnificent buildings soared toward the sky, and a soft golden radiance bathed everything, as if it were Heaven itself!
