After returning from his meeting with Lucian, Lucifer wasted no time delving into his rigorous training regimen. He focused on refining his mana control and balancing the flow of magic within his body, pushing his limits to achieve greater power and precision. Each day began with meditation, where he concentrated on the ebb and flow of mana within him, visualizing it as a river coursing through his veins. This practice helped him enhance his control over his magical energies, ensuring that he could channel them efficiently in battle.
