Ren Yu's progress through the Core Formation Realm was marked by significant milestones. Each stage demanded more profound insights and a deeper understanding of the world's Qi. As he reached Core Formation Stage 1, he began forming his internal core, carefully solidifying the energy within him. The process was intricate and required a delicate balance, but Ren Yu's prior experiences and rigorous training prepared him well for this challenge.
As he advanced to Core Formation Stage 4, Ren Yu felt his core stabilizing. He worked on refining his techniques, focusing on enhancing his core's potency. This stage required intense concentration and meticulous effort, but it also brought him closer to understanding the limits imposed by Blue Star. He knew that his progress was a delicate dance, balancing his cultivation with the world's natural resistance.
One day, while practicing in the seclusion of his chosen retreat, Ren Yu felt the world's energy shift subtly. It was a reminder that he was approaching a critical point in his cultivation journey. As he reached Core Formation Stage 7, the energy he controlled became more refined and potent. He spent countless hours meditating, absorbing the world's Qi, and integrating it seamlessly into his core.
Ren Yu knew that the final stages of Core Formation would be the most challenging. By the time he reached Core Formation Stage 9, his core was robust, and his control over Qi was masterful. He had achieved the highest level of power permitted by Blue Star. However, he also understood that pushing beyond this realm would invite the world's rejection, a force too powerful to contend with in his current realm.
Ren Yu stood on a cliff, overlooking the valley below, feeling the immense energy of the world coursing through him. The dawn broke, casting a golden glow over the landscape. He closed his eyes, taking a deep breath, and focused his mind. The spiritual rejuvenation was upon him, and he was ready.
"The world has its limits," Ren Yu thought, his resolve solidifying. "I must navigate these boundaries wisely. For now, I will focus on perfecting my cultivation and preparing for whatever lies beyond."
With renewed determination, Ren Yu continued his cultivation, steadily advancing through the final stages of Core Formation. He meticulously refined his techniques, ensuring his core was as powerful and stable as possible. His understanding of the world's balance grew deeper, and he prepared himself for the day he might challenge these limits.
Ren Yu's journey was far from over, but he was ready to face the challenges and seize the opportunities that lay ahead. His ultimate goal was clear: to master the Core Formation Realm fully, establish his strength, and understand the world's intricate balance and why the upper limit is only at the Core Formation before considering any further ascension. He knew that his path would require caution, wisdom, and unyielding determination. And he was prepared to give it all.
