The shadow underwater was detected by radar upon entering the waters near the island country.

The warships of the island country launched an attack, but after two nuclear torpedoes were fired, they disappeared without causing any waves.

The shadow underwater continued steadily towards the mainland of the island country, showing no signs of stopping.

The island country dispatched six submarines for reconnaissance, but the underwater shadow was too deep.

After the six submarines reached a depth of four kilometers underwater, they completely lost their propulsion.

The ocean had undergone changes, with countless mutated fish relentlessly attacking the submarines.

These mutated fish were several times larger than their original size, and some anglerfish even developed the ability to become invisible.

One of the submarines approached a bright light, emitted by a lantern-shaped flesh ball.

By the time the personnel in the submarine reacted, the enormous anglerfish hidden in the darkness had already launched an attack.

Its massive mouth swallowed half of the submarine, and its steel-like teeth pierced through the submarine's hull.

At that moment, the people of the world realized that the ocean had become an extremely terrifying place.

The once docile seafood, easily caught and consumed by humans, had transformed into monstrous creatures capable of killing at any time.

After devouring the entire submarine, the enormous anglerfish disappeared into the vast darkness as if it had never appeared.

Meanwhile, the Ocean Fortress No. 055 discovered numerous octopuses without claws.

They were smaller than before, without claws, but their bodies were abnormally swollen.

Once they touched something, they would explode like a bomb, releasing a thick sulfuric acid.

This concentrated sulfuric acid could corrode ordinary metals and burn a large area of human skin upon contact.

What frightened us the most was their reproductive ability.

According to relevant research, these creatures could give birth to ten million offspring within twenty-four hours.

In the following forty-eight hours, they would complete their development, forming a vast swarm.

If a ship crossed this swarm of exploding octopuses, the entire vessel would be completely dissolved.

However, these explosive octopuses only detonated when faced with danger and would not explode under normal circumstances.

Nevertheless, in the mainland of the island country, the seafood had already undergone unpredictable changes.

Their prized salmon and tuna had mutated into even more terrifying creatures.

During the preparation of tuna in sushi restaurants, the bluefin tuna successfully counterattacked the chef.

The enormous bluefin tuna had learned the skill of playing dead. When the chef moved to cut it, its sharp fin severed his throat.

As a result, the island country's culinary association issued a notice requiring confirmation of the true death of a tuna before consumption.

In an uncertain state, the tuna must be securely fastened to the cutting board with metal equipment, maintaining a safe distance.

A few days later, a mass poisoning incident occurred in a sushi restaurant, resulting in the death of all customers.

After an investigation, the island country's culinary association issued a notice stating that salmon should no longer be consumed.

They had developed a special toxin in their bodies, which, when mixed with the flesh of the tuna, would be lethal if consumed.

Currently, there is no known antidote for this toxin.

Prior to the arrival of the enormous shadow at the mainland of the island country, large-scale poisoning incidents had already occurred due to seafood.

Some even began to proclaim: The end is near...
