Reborn as Jon Snow with God System

Jon Snow stood on the threshold of the Training Dimension of the Gods, the culmination of a decade of rigorous training and profound growth. At just seventeen, he was ready to return to the world he had left behind as a seven-year-old boy. The dimension had been his crucible, a place where he had transformed from a child into a warrior of extraordinary prowess.

His dragon, Ghidorah, was a testament to the dimension's power. Born three years prior, Ghidorah had grown to a size comparable to the dragons of Westeros, his scales gleaming with a potent mix of chakra and magic. The dragon was now an awe-inspiring force, capable of unleashing fire from all three of his heads, emitting gravity beams, and summoning storms and lightning with the mere movement of his wings. His regenerative abilities were unmatched, making him a nearly indomitable force.

Jon's bond with Ghidorah was profound. Through his Warg abilities, he could experience the world through the dragon's eyes, sensing and understanding the environment as if it were his own. This deep connection had forged a unique synergy between them, allowing them to act in perfect unison.

Over the past ten years, Jon had achieved unparalleled mastery in several disciplines. He had perfected the Wood Release to the extent that he wielded 100 percent of Hashirama Senju's power. His command over nature's elements was flawless, and he had mastered all techniques from the Naruto world, including the Flying Thunder God, Particle Style, and various elemental releases. His repertoire of jutsus was vast, encompassing thousands of techniques.

In addition to his skills from the Naruto universe, Jon had also mastered the magic of the Game of Thrones world. He could perform complex rituals and wield magical energies with ease. His proficiency extended to the breathing techniques of the Demon Slayer world, integrating them with his chakra to create a formidable style of swordsmanship. His mastery of the Arthur Dayne template had further refined his two-sword style, making him a fearsome combatant.

Jon knew the world was not ready to witness Ghidorah's full potential. The dragon's size and strength would cause chaos if introduced to the outside world. For this reason, Jon had decided to leave Ghidorah in the Training Dimension, setting its time flow to match the world of Game of Thrones[1 day outside is 1 day inside]. This way, time would pass much slower for Ghidorah, ensuring that the dragon would continue to grow and thrive in a safe environment. the training dimension was heavens to anyone, you can get anything to eat, you just have to say it the dimension and it will provide it. the dragon would not have to worry about food.

Jon approached Ghidorah, who lay curled in the center of their training grounds. The dragon's three heads turned toward him, and Jon could sense the mix of confusion and displeasure in their shared bond. He explained his decision to leave Ghidorah behind, emphasizing that the world was not yet ready for such a formidable presence.

Ghidorah's response was a resonant screech, a sound that echoed through the dimension. The dragon's frustration was clear, but Jon reassured him that the dimension's time flow would allow him to continue growing without interruption. Ghidorah's desire for comfort and rest made the decision easier for him to accept. With a final, mournful roar, Ghidorah settled back into his place, his displeasure tempered by his love for the tranquility of the dimension.

Jon activated the departure sequence, a swirling vortex of energy opening before him. He took one last look around the dimension, a place that had been both his sanctuary and his crucible. Stepping into the vortex, he felt a surge of anticipation as he prepared to re-enter the world he had left behind.

Emerging from the vortex, Jon found himself back in his old room. The chamber was unchanged, a stark reminder of how little time had passed in the real world compared to the decade he had experienced in the dimension. The room, frozen in time, bore witness to Jon's transformation. He was no longer the seven-year-old boy who had entered the dimension but a seventeen-year-old warrior of immense power.
