Chapter 913 -907: Summoning a New Typhoon

A typhoon is a low-pressure vortex that appears over tropical or subtropical ocean surfaces—a powerful and profound tropical weather system.

When the ocean surface is exposed to sunlight, it generates strong cumulonimbus clouds. The hot air within these cumulonimbus clouds ascends, while cooler surrounding air continuously flows in to replace it, rising again upon heating, forming intense convection—this is a tropical depression.

As the rising hot air carries water vapor to the top of the cloud mass, it evaporates, enlarging the cloud cluster while intensifying this phenomenon.

Eventually, when the expanded cloud mass becomes large enough, it rotates under the influence of the Earth’s magnetic field and axial rotation. Once the intensity reaches a certain threshold, the tropical depression evolves into a typhoon.

Because typhoons rotate, they naturally move along atmospheric circulation, driven by the summer monsoon toward the Asian Continent.

Since tropical depressions originate from cumulonimbus clouds, they are typically laden with abundant water vapor, often accompanied by strong winds and heavy rainfall upon making landfall.

While this can result in severe secondary disasters, it simultaneously provides the Asian Continent with a rich source of water vapor.

Thus, in a sense, typhoons and tropical depressions are indeed indispensable components of atmospheric circulation.

Of course, when the intensity of a tropical depression reaches the typhoon level, it becomes a terrifying disaster. With humanity’s current scientific and technological capabilities, preventing a typhoon’s occurrence would be extremely difficult.

Although humans theoretically possess the ability to stop a typhoon from forming, the cost of doing so is beyond what humanity could endure.

After all, whether it’s using nuclear bombs to strike a typhoon or igniting large-scale oil fires on the ocean surface to heat the air and alter atmospheric circulation, the repercussions of these actions far outweigh the economic losses caused by a landfalling typhoon.

It’s akin to encountering a car accident at an intersection—a car charging toward you, and a nearby tank fires its cannon to destroy the incoming vehicle. Yet, the resulting explosion also blasts you away, leaving your head smashed like a rotten watermelon.

The costs incurred do not at all match the gains obtained.

Except for the Soviet Union’s nuclear-powered reservoir-building endeavors, no one else in the world would be this insane.

But for Transcendents, while they may be incapable of stopping a typhoon entirely, they can certainly weaken or redirect it.

Especially for a Water Elemental Lord—standing atop the sea, she possesses limitless power and a home-field advantage.

Upon receiving Jounouchi Hiromi’s request, Ni Nasu had already arrived at the ocean. Her current position was directly on the typhoon’s projected path, situated between the typhoon and Tokyo.

Although the sea around Ni Nasu remained relatively calm at the moment, she was already able to see the typhoon with her own eyes.

Gazing at the enormous cloud masses that obscured the sky, feeling the transmitted information through the water vapor—the typhoon’s sheer destructive power derived solely from its rotation—Ni Nasu’s eyes lit up.

“This is a typhoon? Just water vapor evaporation and rotation alone can produce such frightening power—it’s truly incredible!” Ni Nasu marveled emotionally in the language of the water element. For a Water Elemental Lord, the potent, water-related natural phenomenon of a typhoon was precisely the kind of force she aspired to command.

As Ni Nasu’s thoughts emerged, the surrounding water vapor began to rotate as well—only in the opposite direction.

Ni Nasu wasn’t particularly knowledgeable about meteorology or typhoons, but she could sense that the typhoon’s immense power stemmed from its rotation. If she could slow its rotation, the typhoon’s strength would naturally diminish.

The simplest method to decelerate a typhoon’s rotation was, of course, to apply an opposing force—to forcibly halt its spin.

This was something Ni Nasu could achieve. Her initial plan was to enter the typhoon itself, controlling the water vapor within to slow its rotation. But upon witnessing the typhoon’s might firsthand, Ni Nasu was tempted to test this power by creating a counter-rotating typhoon to collide with the natural one.

Ni Nasu unleashed her full power, rapidly evaporating massive amounts of water vapor from the surrounding ocean. She spun the vapor, sending it soaring into the sky to form a dense cloud layer.

As Ni Nasu continued to manipulate it, the cloud layer gradually began to rotate autonomously and increasing in speed.

Before long, the vapor no longer needed her relentless exertion to maintain rotation; it had already gained inertia and its own circulation—a new typhoon was born.

However, this typhoon would be impossible in real-world scenarios. Due to the Earth’s rotation and geomagnetic deviations, typhoons and vortices always spin in the same direction within either hemisphere. Opposing typhoons on the same hemisphere simply don’t happen.

Yet, under the influence of a Water Elemental Lord, this impossible phenomenon manifested.

As Ni Nasu continued to control the evaporation and rotation of water vapor over the surrounding sea, the typhoon she had created grew larger.

Hours later, the naturally forming typhoon drew closer to Ni Nasu, and the typhoon she had conjured had reached roughly a third of the size of the natural one.

At this point, Ni Nasu felt she had reached her limit. Although she could continue evaporating water vapor and spinning it to feed her typhoon, she risked losing control of it altogether if she pressed on.

Even now, Ni Nasu’s control over her typhoon was weakening, though she still retained enough dominance to prevent it from moving unpredictably. She could ensure it collided with the natural typhoon, nullifying its strength.

If Ni Nasu lost control of her typhoon, it might fail to hit the natural typhoon at all, rendering her efforts futile—or worse yet, exacerbating the natural typhoon’s strength, resulting in catastrophic consequences.

While Ni Nasu couldn’t completely neutralize the natural typhoon’s force, the typhoon she summoned had reached a strength equivalent to one-third of the natural typhoon, sufficient to significantly weaken its impact and fulfill her promise to Jounouchi Hiromi.

Thus, upon realizing her limits, Ni Nasu directed her summoned typhoon along the natural typhoon’s path, sending it crashing forward!
