Three more years of absolute isolation passed. The third, fourth, and fifth years slipped away. Nyuro was now exactly five years old. Inside the servants' annex, the space no longer resembled a human dwelling; the wooden floor had splintered under the weight of Nyuro's aura, and the walls were covered with the marks of small fists that had pierced the room's reinforced steel lining.
Nyuro stood in the center of the room, his icy blue hair rising slightly from the pressure of his energy. He had the body of a five-year-old, but his muscles were sculpted with extreme precision, and his golden eyes carried a wisdom and a terror that surpassed his age by centuries.

Super Saiyan: Conquering Space
As Nyuro stood in silence, he closed his eyes and summoned the golden energy latent in his blood. He no longer needed intense rage; he had tamed this transformation through three years of agony.
"Haaaah!"
A searing golden aura exploded from Nyuro's small body. His blue hair turned a brilliant gold, and his eyes shifted to a piercing emerald green. The temperature in the room skyrocketed to the point where the wood began to char into coal within seconds.
[Power Update - Super Saiyan Transformation]
Current Power: 300,000,000 \times 50 = 15,000,000,000 (15 Billion Ki).
System Warning: A five-year-old body can barely withstand this pressure. Safe usage duration: 10 minutes only.
Nyuro looked at his golden hands. "15 billion... this power is enough to erase a planet or even an entire solar system from existence with a single strike. But the System warned me... high-level cultivators possess cosmic laws that transcend physical strength. I must be careful."
Merging Powers and Martial Mastery
Nyuro deactivated Super Saiyan, returning to his base energy (300 million). He then decided to test the fusion of his new powers.
"Kaioken... times two!"
A crimson aura surged over his base energy. He began moving through the room at speeds a human eye could not track, practicing the Martial Arts granted to him by the System—movements that combined Saiyan brutality with cultivator precision. Each strike against the air sent a powerful shockwave through the reinforced room.
[System Notification]
Kaioken successfully merged with Base Power.
Current Power (Kaioken x2): 600,000,000 (600 Million Ki).
Five Years... The Continuous Vow
Mira entered the room to find Nyuro sitting in a meditative posture. She felt a terrifying aura radiating from him—an aura that made the hair on her arms stand up in fear without her knowing why. Nyuro no longer looked at her as a child in need of protection, but as a king waiting to reclaim his throne.
"Mira..." Nyuro spoke in a voice that was eerily calm and steady. "From today... bring only a little food. I will be busy... for a very long time."
Nyuro closed his eyes and began his sixth year of training, where the gravity in his room was now set to 100 times Earth's gravity. 300 million was the foundation, Super Saiyan was the secret weapon, and the next fifteen years would be the forge in which the strongest warrior the cultivation world has ever known would be hammered out—far from his father's sight, and far from the world system that rejected him.
