I became the King of Ryukyu

Just as the functional debugging entered a critical stage, the dark water flow behind them suddenly changed.

A two-and-a-half-meter-long blue-ringed sea serpent silently crept in, its scarlet tongue flicking in and out, locking onto the snow-white, unfamiliar-looking little white dragon.

Electric eels are not found in East Asian waters. This native sea snake had never seen one before and mistook it for an exceptionally plump ordinary eel. It prepared to inject venom into the eel with its fangs and then feast on it.

However, its hunting behavior was revealed the moment it started.

Those who use poison are no match for those who use electricity.

The low-pressure magnetic field within a ten-meter radius of the White Dragon had already completely covered the surrounding waters, allowing the opponent's trajectory, speed, and location to be accurately captured.

Before the sea serpent could get close enough to attack, the little white dragon suddenly reversed its body, and the muscles in its tail instantly tensed and burst forth.

laugh--!

A thin, pale blue arc of electricity suddenly exploded in the murky seawater, sweeping outwards with a sharp, numbing current.

The attacking blue-ringed sea serpent instantly stiffened, its body violently contracted, and it sank straight to the bottom of the water.

The little white dragon stepped forward and swallowed it whole.

The system notification sounded in Zheng Yi's mind right on time:

[Defeat the Blue-ringed Sea Serpent to gain a small amount of experience points]

[General Xiaobailong's level has been increased! Current level: Lv3]

The moment it broke through to the next level, warm energy instantly washed over the little white dragon's bones and muscles, causing its body to visibly swell. At the same time, a strong sense of hunger swept over its body.

Zheng Yi shared the five senses with the general and clearly perceived the throbbing of this transformation. He immediately controlled the little white dragon to completely digest the sea snake's flesh and blood, while precisely outputting electric current to continuously stimulate the hypothalamus, kidneys, gills and other core organs, guiding the physical transformation brought about by the level breakthrough and maximizing the enhancement of the body's adaptability.

Time passed slowly until evening.

After several hours of refinement and transformation, the white dragon's kidney salt excretion efficiency has increased dramatically, and its gill ion cells have completely switched functions, completely breaking free from the limitations of freshwater organisms and perfectly adapting to the marine environment.

An overwhelming sense of power filled Zheng Yi's body. He felt this wild power and controlled the three-meter-long snow-white electric eel, swimming freely in the estuary and unleashing its powerful physique after its metamorphosis.

At three meters long, it already surpasses the biological limits of all wild electric eels. In this estuary area, it is undoubtedly the dominant species.

After fully adapting to the salinity, Zheng Yi stopped and steered the little white dragon to plunge into the vast open sea.

The seabed near the estuary presents a completely different scene. Sunlight filters through the shallow water, refracting into shimmering waves. Underwater coral reefs are scattered among them, with colorful tropical fish swimming among them. Various shellfish and seaweed grow on the rocks, creating a tranquil yet vibrant atmosphere. The deeper one ventures into the sea, the dimmer the light becomes, the water temperature slowly decreases, and the surrounding atmosphere of the ocean becomes deep and oppressive.

The waters off Okinawa have complex topography and extremely extreme depth variations.

After traveling only a few hundred meters, the originally gentle shallow seabed suddenly broke and collapsed, and the water depth plummeted from a shallow beach of more than ten meters to a deep sea of ​​more than two hundred meters. A dark and deep giant trench stretched across the seabed, with steep cliffs and heavy black mist, like the gaping maw of the sea, exuding a heart-palpitating sense of oppression.

The moment you descend into the trench, the terrifying pressure of the deep sea suddenly engulfs you.

The extreme pressure from the water depth of over two hundred meters was squeezing the little white dragon's body. Zheng Yi, who shared all five senses, clearly felt his chest being crushed by a tremendous force, his bones continuously emitting a faint creaking sound under the pressure, his blood and qi stagnating throughout his body, and even his consciousness was suppressed, making him feel slightly suffocated, and his head was dizzy in waves.

A strong sense of suffocation and oppression from the deep sea washes over you.

Knowing that his current physical condition could not support a long stay in the deep sea, Zheng Yi was preparing to control the little white dragon to retreat to the shallow sea to rest. His gaze swept over the dark shadows of the trench, but suddenly froze.

In the deep, dark shadows of the seabed, a massive black silhouette lies silently, half-hidden by thick seaweed and seabed silt. Its imposing shape is clearly not a natural reef.

He immediately steered the little white dragon to approach slowly, and with the faint light of the deep sea, he could see the whole picture—it was an ancient shipwreck covered with seaweed, shells and parasites, its hull decayed and broken, quietly sleeping in the deep sea trench.

Thank goodness, Zheng Yi really had no intention of searching for treasure underwater.

Although many stories depict the search for shipwrecks and salvage of treasures at the bottom of the sea, such as the old single-player game "Romance of the Three Kingdoms" that he played in his previous life, salvaging shipwrecks was an important means of getting rich.

Zheng Yi thought that this should be discussed after he had his own ocean-going vessels.

Located at the heart of East Asian maritime trade, the Ryukyu Islands have seen a constant flow of merchant ships from China, Southeast Asia, and Japan for centuries, with countless vessels capsizing and sinking due to typhoons, reefs, and other maritime disasters.

According to official statistics, there are thousands of shipwrecks in this coastal area that have not yet been explored or salvaged.

It's quite unexpected that this shipwreck, so close to the river mouth, remained undiscovered.

Zheng Yi estimates that the unique topography of this seabed, which suddenly breaks off and forms a trench 200 meters deep, perfectly evaded the detection of conventional underwater sonar, allowing it to remain hidden until now.

It's also possible that it was already discovered, but salvage was too difficult due to its location in the trench, or the cost of salvage was not commensurate with the value of the cargo on board. Therefore, the salvage plan was shelved.

Zheng Yi had no intention of salvaging the entire ship; he only planned to take some valuables.

Given that Xiaobailong's current physical strength was insufficient to withstand long-term deep-sea operations, Zheng Yi silently noted down the approximate location of the sunken ship, then decisively changed course and retreated at full speed to the mouth of the Anlichuan River.

Next comes the moment of leveling up and transforming without holding back.

The estuary area is rich in fish and marine mammals, making it a natural training ground.

Zheng Yi activated the ultimate leveling mode, controlling the little white dragon to roam the waters. The magnetic field was activated throughout, and any fish, shrimp, or small marine predators that entered the range were instantly paralyzed by the high-voltage current.

Corona, devour, absorb, strengthen, in a continuous cycle.

He specifically utilized the upgraded energy to repeatedly temper the hypothalamus growth center, raise the upper limit of kidney salt excretion, and continuously activate the activity of gill ion cells. Each time he upgraded his diet, the little white dragon's marine survival ability and physical strength underwent a qualitative change.

It's like an immersive gamer grinding levels, steadily building up absolute strength.

During the time I was leveling up in the river mouth, a funny little incident happened.

The wealthy straw-hat-wearing uncle that Zheng Yi would bump into every morning during his run was an avid sea fisherman, but he was either always empty-handed or on his way to being empty-handed.

Today, he decided to head to the mouth of the Anlichuan River, which is rumored to be teeming with fish. As soon as he set up his expensive fishing gear, he began to chat with his fellow anglers.

"Everyone says there are lots of fish in this estuary, but I don't think you need any special skills. Just throw in a straight hook, and you're guaranteed to catch some!"

The man in the straw hat spoke with such confidence that it drew sidelong glances from the anglers around him.
