Reborn as Jon Snow with God System

Jon Snow led the giants and mammoths steadily across the frozen wastelands of the lands beyond the Wall. The sheer size of the giants and their powerful strides allowed them to cover vast distances quickly, though they were still far behind the main group of 100,000 wildlings under his protection. Jon's mind, however, was preoccupied with a larger dilemma.

The land he had discovered was vast and barren, cursed by unyielding winters and relentless icy winds. Though his abilities as the heir to Hashirama Senju's power allowed him to manipulate the earth and convert the frozen terrain into fertile land, the greater challenge loomed overhead—the weather. The brutal cold and lack of sunlight made survival nearly impossible, even if the soil itself became fertile.

Jon racked his mind for solutions. He could use his techniques to manipulate the weather temporarily, but the scale required was far beyond his capabilities. He needed a permanent change, something that would bring warmth and life to a region spanning hundreds of kilometers.

He thought of his dragon, King Ghidorah. The mighty three-headed dragon, a being of unparalleled power and a natural calamity, had the ability to command the weather. Ghidorah's storms could ravage entire continents, and Jon was certain that, once fully grown, the dragon could reshape the climate to his will. However, Ghidorah was still maturing.

"It's been one and a half years since I left him in the training dimension," Jon muttered to himself. "Perhaps it's time I checked on him."

Leaving a wood clone behind to guide the giants and mammoths to the main group, Jon quickly entered into the training dimension of god—a realm of infinite space and untamed energy.

The air buzzed with magic and chakra, a potent combination that Jon had spent years mastering. He closed his eyes, reaching out with his senses to locate Ghidorah. The dragon's presence was overwhelming, a beacon of raw power that shook the very fabric of the dimension.

Jon followed the pull of energy and soon found Ghidorah, resting in a massive clearing. The dragon was colossal, its three heads resting against the ground as it slumbered. Its golden scales shimmered even in the dim light of the dimension, exuding an aura of invincibility.

Jon's jaw dropped as he took in the sight. Ghidorah had grown significantly since he had last seen him. The dragon's size had nearly doubled, its wings now vast enough to blot out the sky. The sheer power radiating from Ghidorah was staggering.

"How is this possible?" Jon whispered to himself. "He's grown so much… and he's been sleeping the entire time."

Curious, Jon reached out to the system embedded within him, the mysterious tool that had guided him ever since he was reborn into this world.

"System," Jon called. "How has Ghidorah grown so much while sleeping?"

A soft chime echoed in his mind. Ding! "Host, King Ghidorah absorbs magic and chakra from his surroundings even while at rest. His body naturally evolves by drawing in energy, allowing him to grow stronger over time."

Jon nodded, his suspicions confirmed. It seemed Ghidorah was more than just a creature of destruction—he was a being that thrived in an environment of pure energy, feeding on the dimension's magic to enhance his power.

"System," Jon continued. "How long will it take for Ghidorah to reach his fully mature state?"

Ding! "Host, King Ghidorah requires 20 more years to reach his prime form and achieve his full strength."

Jon frowned. "Twenty years? That's… much longer than I expected. The dragons of this world mature in less than a decade. Why does Ghidorah take so long?"

Ding! "Host, King Ghidorah is not an ordinary dragon. He is a being of unparalleled might, designed as a natural calamity. His development is slower but far surpasses that of any dragon from this world. Once fully grown, he will be unmatched in power."

Jon sighed, running a hand through his hair. It made sense. Ghidorah was no ordinary creature; he was the King of the Skies, a destroyer of worlds, and a harbinger of storms. Patience was necessary, but it was a resource he could scarcely afford.

"One more thing, system," Jon asked. "What is Ghidorah's lifespan?"

Ding! "Host, King Ghidorah can live for millions of years. If he continues to absorb magic and chakra, he has the potential to become truly immortal."

Jon exhaled, impressed yet unsurprised. Ghidorah's nature as a near-divine being aligned with these revelations. A dragon capable of reshaping entire ecosystems and living indefinitely—Ghidorah truly was one of a kind.

Jon stepped closer to the slumbering dragon, feeling the immense heat radiating from its body. He placed a hand on one of its massive golden scales.

"It's time to wake up," he said softly.

For a moment, nothing happened. Then, the air around Ghidorah began to crackle with electricity. The dragon's three heads stirred, their glowing eyes opening slowly. The central head lifted first, gazing down at Jon with a mix of recognition and curiosity. The other two heads followed, their movements graceful yet intimidating.

"Good to see you again," Jon said, smiling despite the imposing sight.

Ghidorah let out a low growl, the sound reverberating through the dimension like thunder. The dragon stretched its wings, shaking off the remnants of its slumber.

"I need your help," Jon continued. "The land we're heading to is harsh and unforgiving. The weather itself is our greatest enemy. I need you to help me change it, to bring warmth and life to the people who follow me."

Ghidorah's central head tilted, as if considering Jon's words. The dragon's other two heads exchanged glances, their golden scales shimmering with latent power.

"I know you're still growing," Jon admitted. "But your strength is already far beyond anything this world has ever seen. Together, we can reshape the future."

The dragon responded with a deep roar, its three heads rising high into the air. Lightning crackled around its body, illuminating the dimension with flashes of golden light. It was a declaration of power, a promise to aid Jon in his quest.

Jon nodded, his determination renewed. "Let's get to work, then. We have a kingdom to build."

As Ghidorah spread its massive wings, Jon couldn't help but feel a surge of hope. With the mighty three-headed dragon at his side, even the unforgiving land beyond the Wall could be tamed. The journey ahead would be long and arduous, but Jon Snow, the would-be king, was ready to face it. Together with Ghidorah, he would create a new world—one where giants, wildlings, and men could live without fear of the cold or the dead.

The storm was coming, but this time, it would be theirs to command.
